description Publicationkeyboard_double_arrow_right Article 2024 United Kingdom, NetherlandsPublisher:Elsevier BV Aude Duval-Arnould; Luc Bulot; Moussa Masrour; Mike Simmons; Alain Bonnot; Rémi Charton; Jonathan Redfern; Stefan Schröder;International audience; A major global marine transgression occurred during the Callovian to Early Kimmeridgian, which was interrupted locally by a hiatus during the Late Callovian to Early Oxfordian. The transgression may have been a major driver for extensive coral buildup development in the Oxfordian. The depositional hiatus may be related to a combination of eustasy, local tectonic activity and hinterland movements, highlighting the potential influence of tectonism on sedimentary evolution in sedimentary basins. Whilst a regional Late Callovian-Early Oxfordian hiatus has been recorded extensively in the Tethys realm, this study has improved the biostratigraphic and sedimentary record from Morocco, and for the first time documents the Late Callovian-Early Oxfordian depositional hiatus in the Atlantic realm. Detailed sedimentary facies analysis of Callovian to Oxfordian carbonates and siliciclastics (Ouanamane Formation) demonstrates a major transgression from continental and coastal sediments, through oolitic mid-inner ramp deposits, brachiopod-rich middle ramp deposits, and ultimately to outer ramp marls, sharply overlain by Middle Oxfordian coral buildups across the basin. Repeated hard- and firmgrounds and bioturbated bed tops highlight transgressive surfaces traceable basinwide, which suggests low sedimentation rates in the upper Ouanamane Formation. Localized siliciclastic input is evidence for episodes of erosion in the same interval. Collection of new fossil specimens (ammonites, brachiopods, echinoderms, foraminifera) and revision of existing fossil material suggest this interval corresponds to a hiatus or condensed section in the Callovian-Oxfordian transition. The uppermost part of the Ouanamane Formation is of early Middle Oxfordian age and is directly overlain by Middle Oxfordian coral buildups. Onset of buildup construction is considered synchronous based on the new biostratigraphic data. Observations in Moroco compare with the sedimentary evolution around the Tethys, and in particular with the Arabian Plate. The Callovian-Oxfordian depositional hiatus corresponds to eustatic sea level changes, which were possibly driven by global cooling, and was likely overprinted by local tectonics.

Roche; Florence Mazier; Marco Davoli; Jens-Christian Svenning; Dave van Wees; Elena A. Pearce; Ralph Fyfe; Wil Roebroeks; Fulco Scherjon;International audience; This article focuses on hunter-gatherer impact on interglacial vegetation in Europe, using a case study from the Early Holocene (9200-8700 BP). We present a novel agent-based model, hereafter referred to as HUMLAND (HUMan impact on LANDscapes), specifically developed to define key factors in continental-level vegetation changes via assessment of differences between pollen-based reconstruction and dynamic global vegetation model output (climate-based vegetation cover). The identified significant difference between these two datasets can be partially explained by the difference in the models themselves, but also by the fact that climate is not the sole factor responsible for vegetation change. Sensitivity analysis of HUMLAND showed that the intensity of anthropogenic vegetation modification mainly depended on three factors: the number of groups present, their preferences for vegetation openness around campsites, and the size of an area impacted by humans. Overall, both climate and human activities had strong impacts on vegetation openness during the study period. Our modelling results support the hypothesis that European ecosystems were strongly shaped by human activities already in the Mesolithic.

Germanium (Ge) is a critical raw material used in high-technology industry (i.e., optical industry) applications, and it is predominantly concentrated in coals and Zn-rich deposits. Previous studies on Zn-rich deposits have documented a correlation between Ge enrichment and the Cu, Ag, and/or Pb-Mn contents in the sphalerite crystal lattice. In this study, we observed Ge-rich nanoparticles hosted in Cu-poor sphalerite from the Banbianjie Zn-Ge deposit (>800 t graded at ∼100 ppm Ge), located in southwest China. Laser-ablation−inductively coupled plasma−mass spectroscopy (LA-ICP-MS) analyses revealed that sphalerite contains very heterogeneous Ge contents (172−1553 ppm). Germanium contents showed positive correlations with Fe, Mn, and Pb contents and negative correlations with Cd contents. Higher Ge contents were detected in the darker zones, whereas the lighter zones showed systematically low Ge contents and were enriched in Cd. Using transmission electron microscopy (TEM), Zn-Ge-Pb-S nanoparticles were identified in the darker zones of sphalerite. These nanoparticles exhibited Ge/Pb ratios (0.48−1.96) very similar to those measured in sphalerite (0.36−2.04), suggesting that Ge could be essentially hosted within the nanoparticles. We propose that the amounts of Zn-Ge-Pb-S nanoparticles are related to a self-organization model induced by rapid crystal growth. This self-organization processes may control the fluctuations of element concentrations in the boundary layer. This study highlights the importance of studying the nanoscale expression of critical elements to understand their incorporation mechanisms into natural materials.

Understanding what controls global leaf type variation in trees is crucial for comprehending their role in terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our understanding of the factors influencing forest leaf types remains incomplete, leaving us uncertain about the global proportions of needle-leaved, broadleaved, evergreen and deciduous trees. To address these gaps, we conducted a global, ground-sourced assessment of forest leaf-type variation by integrating forest inventory data with comprehensive leaf form (broadleaf vs needle-leaf) and habit (evergreen vs deciduous) records. We found that global variation in leaf habit is primarily driven by isothermality and soil characteristics, while leaf form is predominantly driven by temperature. Given these relationships, we estimate that 38% of global tree individuals are needle-leaved evergreen, 29% are broadleaved evergreen, 27% are broadleaved deciduous and 5% are needle-leaved deciduous. The aboveground biomass distribution among these tree types is approximately 21% (126.4 Gt), 54% (335.7 Gt), 22% (136.2 Gt) and 3% (18.7 Gt), respectively. We further project that, depending on future emissions pathways, 17–34% of forested areas will experience climate conditions by the end of the century that currently support a different forest type, highlighting the intensification of climatic stress on existing forests. By quantifying the distribution of tree leaf types and their corresponding biomass, and identifying regions where climate change will exert greatest pressure on current leaf types, our results can help improve predictions of future terrestrial ecosystem functioning and carbon cycling.

Brickman; Jerome Maller; Chantal Meslin; Jie Chen; Danielle Vienneau; Kees de Hoogh; Bénédicte Jacquemin; Claudine Berr; Marion Mortamais;International audience; Background: Growing epidemiological evidence suggests an adverse relationship between exposure to air pollutants and cognitive health, and this could be related to the effect of air pollution on vascular health.Objective: We aim to evaluate the association between air pollution exposure and a magnetic resonance imaging (MRI) marker of cerebral vascular burden, white matter hyperintensities (WMH).Methods: This cross-sectional analysis used data from the French Three-City Montpellier study. Randomly selected participants 65-80 years of age underwent an MRI examination to estimate their total and regional cerebral WMH volumes. Exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), and black carbon (BC) at the participants' residential address during the 5 years before the MRI examination was estimated with land use regression models. Multinomial and binomial logistic regression assessed the associations between exposure to each of the three pollutants and categories of total and lobar WMH volumes.Results: Participants' (n=582) median age at MRI was 70.7 years [interquartile range (IQR): 6.1], and 52% (n=300) were women. Median exposure to air pollution over the 5 years before MRI acquisition was 24.3 (IQR: 1.7) μg/m3 for PM2.5, 48.9 (14.6) μg/m3 for NO2, and 2.66 (0.60) 10−5/m for BC. We found no significant association between exposure to the three air pollutants and total WMH volume. We found that PM2.5 exposure was significantly associated with higher risk of temporal lobe WMH burden [odds ratio (OR) for an IQR increase=1.82(95% confidence interval: 1.41, 2.36) for the second volume tercile, 2.04 (1.59, 2.61) for the third volume tercile, reference: first volume tercile]. Associations for other regional WMH volumes were inconsistent.Conclusion: In this population-based study in older adults, PM2.5 exposure was associated with increased risk of high WMH volume in the temporal lobe, strengthening the evidence on PM2.5 adverse effect on the brain. Further studies looking at different markers of cerebrovascular damage are still needed to document the potential vascular effects of air pollution.

Castelle; D. Buscombe; S. Vitousek;AbstractSatellite remote sensing is becoming a widely used monitoring technique in coastal sciences. Yet, no benchmarking studies exist that compare the performance of popular satellite-derived shoreline mapping algorithms against standardized sets of inputs and validation data. Here we present a new benchmarking framework to evaluate the accuracy of shoreline change observations extracted from publicly available satellite imagery (Landsat and Sentinel-2). Accuracy and precision of five established shoreline mapping algorithms are evaluated at four sandy beaches with varying geologic and oceanographic conditions. Comparisons against long-term in situ beach surveys reveal that all algorithms provide horizontal accuracy on the order of 10 m at microtidal sites. However, accuracy deteriorates as the tidal range increases, to more than 20 m for a high-energy macrotidal beach (Truc Vert, France) with complex foreshore morphology. The goal of this open-source, collaborative benchmarking framework is to identify areas of improvement for present algorithms, while providing a stepping stone for testing future developments, and ensuring reproducibility of methods across various research groups and applications.

Houghton; Brent Sohngen;Unmanaged land areas are not included in current national reports on greenhouse gas emissions for the Paris Agreement. Here, we argue that carbon dioxide fluxes from all forest land need to be recorded in order to help tracking progress towards global climate targets. Under the Kyoto Protocol, countries agreed that greenhouse emissions and removals from land activities should count towards their climate targets only if arising from direct human-induced effects. However, the Intergovernmental Panel on Climate Change (IPCC) noted that direct human-induced effects on land are deeply intertwined with changing environmental drivers such as increased atmospheric carbon dioxide (CO 2) concentration (indirect effects) and that they cannot be separated through the methods used in national greenhouse gas inventories. Therefore, to facilitate national greenhouse gas inventory reporting, the IPCC Guidelines 1 adopted the concept of 'managed land'-land where countries decide that human interventions and practices have been applied to perform production, ecological or social functions-as a pragmatic proxy for anthropogenic effects. Greenhouse gas fluxes are thus defined as all those occurring on managed land, whether they stem from either direct human-induced effects or from changing environmental drivers. Countries thus only need to estimate and report to the United Nations Framework Convention on Climate Change (UNFCCC) the greenhouse gas fluxes on managed land. While it is good practice to report the area of unmanaged lands in the greenhouse gas inventory, there is no obligation to report greenhouse gas fluxes from these lands. In other words, countries have so far assumed that they have no control over, and are therefore not liable for the greenhouse gas fluxes on unmanaged lands. The current separation, in which only part of the land is reported, makes it impossible to establish a direct link between the fluxes reported to UNFCCC and the observed growth rates of greenhouse gases in the atmosphere. This narrow focus on managed land also contributes to the discrepancy between national greenhouse gas inventories and the estimates for the global net terrestrial carbon flux established by the scientific community (Fig. 1). To a large degree, the mind-boggling range in estimates shown in Fig. 1 results from different ways to define the term 'anthropogenic'. In addition, managed and unmanaged land is delineated in diverse ways, depending whether the delineation is performed by land use researchers, as part of countries' greenhouse gas reporting 2 , through remote sensing approaches or via atmospheric inversion approaches. Furthermore, the definition of managed land as a proxy for anthropogenic emissions and removals is not homogeneous across countries. At present, large areas of unmanaged forest are reported by Brazil, Canada and Russia, while for most developing countries it is often unclear if they consider all forest as managed or not 3. Even less information is available for unmanaged non-forest area, which might include grassland and wetlands.

Vallet; L. Vallet; M. Schwartz; P. Ciais; D. van Wees; A. de Truchis; F. Mouillot;The frequency and intensity of summer droughts and heat waves in Western Europe have been increasing, raising concerns about the emergence of fire hazard in less fire-prone areas. This exposure of old-growth forests hosting unadapted tree species may cause disproportionately large biomass losses compared to those observed in frequently burned Mediterranean ecosystems. Therefore, analyzing fire seasons from the perspective of exposed burned areas alone is insufficient; we must also consider impacts on biomass loss. In this study, we focus on the exceptional 2022 summer fire season in France and use very high-resolution (10 m) satellite data to calculate the burned area, tree height at the national level, and subsequent ecological impact based on biomass loss during fires. Our high-resolution semi-automated detection estimated 42 520 ha of burned area, compared to the 66 393 ha estimated by the European automated remote sensing detection system (EFFIS), including 48 330 ha actually occurring in forests. We show that Mediterranean forests had a lower biomass loss than in previous years, whereas there was a drastic increase in burned area and biomass loss over the Atlantic pine forests and temperate forests. High biomass losses in the Atlantic pine forests were driven by the large burned area (28 600 ha in 2022 vs. 494 ha yr−1 in 2006–2021 period) but mitigated by a low exposed tree biomass mostly located on intensive management areas. Conversely, biomass loss in temperate forests was abnormally high due to both a 15-fold increase in burned area compared to previous years (3300 ha in 2022 vs. 216 ha in the 2006–2021 period) and a high tree biomass of the forests which burned. Overall, the biomass loss (i.e., wood biomass dry weight) was 0.25 Mt in Mediterranean forests and shrublands, 1.74 Mt in the Atlantic pine forest, and 0.57 Mt in temperate forests, amounting to a total loss of 2.553 Mt, equivalent to a 17 % increase of the average natural mortality of all French forests, as reported by the national inventory. A comparison of biomass loss between our estimates and global biomass/burned areas data indicates that higher resolution improves the identification of small fire patches, reduces the commission errors with a more accurate delineation of the perimeter of each fire, and increases the biomass affected. This study paves the way for the development of low-latency, high-accuracy assessment of biomass losses and fire patch contours to deliver a more informative impact-based characterization of each fire year.; La fréquence et l'intensité des sécheresses estivales et des vagues de chaleur en Europe occidentale ont augmenté, suscitant des inquiétudes quant à l'émergence d'un risque d'incendie dans des zones moins sujettes aux incendies. L'exposition de forêts anciennes abritant des espèces d'arbres non adaptées peut entraîner des pertes de biomasse disproportionnées par rapport à celles observées dans les écosystèmes méditerranéens fréquemment incendiés. Par conséquent, l'analyse des saisons des incendies du seul point de vue des zones brûlées exposées est insuffisante ; nous devons également prendre en compte les impacts sur la perte de biomasse. Dans cette étude, nous nous concentrons sur la saison exceptionnelle des incendies de l'été 2022 en France et utilisons des données satellitaires à très haute résolution (10 m) pour calculer la surface brûlée, la hauteur des arbres au niveau national et l'impact écologique subséquent basé sur la perte de biomasse pendant les incendies. Notre détection semi-automatique à haute résolution a permis d'estimer 42 520 ha de surface brûlée, contre 66 393 ha estimés par le système européen automatisé de détection par télédétection (EFFIS), dont 48 330 ha se trouvant effectivement dans des forêts. Nous montrons que les forêts méditerranéennes ont subi une perte de biomasse plus faible que les années précédentes, alors qu'il y a eu une augmentation drastique de la surface brûlée et de la perte de biomasse dans les forêts de pins atlantiques et les forêts tempérées. Les pertes élevées de biomasse dans les forêts de pins atlantiques sont dues à l'étendue des zones brûlées (28 600 ha en 2022 contre 494 ha par an au cours de la période 2006-2021), mais elles sont atténuées par une faible biomasse d'arbres exposés, situés pour la plupart dans des zones de gestion intensive. Inversement, la perte de biomasse dans les forêts tempérées a été anormalement élevée en raison à la fois d'une multiplication par 15 de la superficie brûlée par rapport aux années précédentes (3 300 ha en 2022 contre 216 ha au cours de la période 2006-2021) et d'une biomasse arborée élevée dans les forêts qui ont brûlé. Globalement, la perte de biomasse (c'est-à-dire le poids sec de la biomasse du bois) a été de 0,25 Mt dans les forêts et les arbustes méditerranéens, de 1,74 Mt dans la forêt de pins atlantiques et de 0,57 Mt dans les forêts tempérées, soit une perte totale de 2,553 Mt, ce qui équivaut à une augmentation de 17 % de la mortalité naturelle moyenne de toutes les forêts françaises, telle qu'elle est indiquée dans l'inventaire national. Une comparaison de la perte de biomasse entre nos estimations et les données globales de biomasse/surfaces brûlées indique qu'une résolution plus élevée améliore l'identification des petites taches de feu, réduit les erreurs de commission grâce à une délimitation plus précise du périmètre de chaque feu, et augmente la biomasse affectée. Cette étude ouvre la voie au développement d'une évaluation à faible latence et à haute précision des pertes de biomasse et des contours des taches de feu afin de fournir une caractérisation plus informative basée sur l'impact de chaque année d'incendie.

In practical terms, this means increasing the botanical diversity and delaying mowing of the grasslands to favor fauna diversity and associated ecosystem services. However, it is unknown whether these feeding practices alter rumen microbiota and its association with methane (CH 4) emission, a potent greenhouse gas. The objective of this study was to assess CH 4 emission and rumen microbiota of several dairy breeds fed agroecology diets. Three dairy cattle breeds (Holstein Friesian, Groninger Blaarkop and Jersey) (N = 10 for each breed) were fed three grass silage-based diets that included a proportion of a control silage, an experimental silage composed of late mown grass, and an experimental silage composed of diverse botanical species. Cows were fed for 13 weeks with gradual adjustment of the proportion of each silage. Rumen fluid was sampled during the weeks that corresponded to the highest proportion of each silage in the diet. Rumen microbiota was characterized through 16 s rRNA gene amplicon sequencing for its richness and diversity, as well as its compositions according to diet type and breed. Production performances and CH 4 emission were also measured. Methane production (g/d) was similar between the control and the agroecological diets. Cows fed the experimental diets had a different rumen microbiota composition than cows fed control diet. The cows fed the agroecological diets presented reduced relative abundances of Rumminoccocaeae, and higher relative abundances of Chirstensenellaceae and Methanobrevibacter than cows fed the control diet. Besides, the cows fed the agroecological diets presented a richer (P < 0.01) and more diverse (P < 0.01) rumen microbiota. Overall, this study highlights how feeding practices that comply with agroecology principles, and applied under practical conditions, shaped the rumen microbiota of specialized and dual-purpose cattle breeds.

description Publicationkeyboard_double_arrow_right Article 2024 United Kingdom, NetherlandsPublisher:Elsevier BV Aude Duval-Arnould; Luc Bulot; Moussa Masrour; Mike Simmons; Alain Bonnot; Rémi Charton; Jonathan Redfern; Stefan Schröder;International audience; A major global marine transgression occurred during the Callovian to Early Kimmeridgian, which was interrupted locally by a hiatus during the Late Callovian to Early Oxfordian. The transgression may have been a major driver for extensive coral buildup development in the Oxfordian. The depositional hiatus may be related to a combination of eustasy, local tectonic activity and hinterland movements, highlighting the potential influence of tectonism on sedimentary evolution in sedimentary basins. Whilst a regional Late Callovian-Early Oxfordian hiatus has been recorded extensively in the Tethys realm, this study has improved the biostratigraphic and sedimentary record from Morocco, and for the first time documents the Late Callovian-Early Oxfordian depositional hiatus in the Atlantic realm. Detailed sedimentary facies analysis of Callovian to Oxfordian carbonates and siliciclastics (Ouanamane Formation) demonstrates a major transgression from continental and coastal sediments, through oolitic mid-inner ramp deposits, brachiopod-rich middle ramp deposits, and ultimately to outer ramp marls, sharply overlain by Middle Oxfordian coral buildups across the basin. Repeated hard- and firmgrounds and bioturbated bed tops highlight transgressive surfaces traceable basinwide, which suggests low sedimentation rates in the upper Ouanamane Formation. Localized siliciclastic input is evidence for episodes of erosion in the same interval. Collection of new fossil specimens (ammonites, brachiopods, echinoderms, foraminifera) and revision of existing fossil material suggest this interval corresponds to a hiatus or condensed section in the Callovian-Oxfordian transition. The uppermost part of the Ouanamane Formation is of early Middle Oxfordian age and is directly overlain by Middle Oxfordian coral buildups. Onset of buildup construction is considered synchronous based on the new biostratigraphic data. Observations in Moroco compare with the sedimentary evolution around the Tethys, and in particular with the Arabian Plate. The Callovian-Oxfordian depositional hiatus corresponds to eustatic sea level changes, which were possibly driven by global cooling, and was likely overprinted by local tectonics.

Roche; Florence Mazier; Marco Davoli; Jens-Christian Svenning; Dave van Wees; Elena A. Pearce; Ralph Fyfe; Wil Roebroeks; Fulco Scherjon;International audience; This article focuses on hunter-gatherer impact on interglacial vegetation in Europe, using a case study from the Early Holocene (9200-8700 BP). We present a novel agent-based model, hereafter referred to as HUMLAND (HUMan impact on LANDscapes), specifically developed to define key factors in continental-level vegetation changes via assessment of differences between pollen-based reconstruction and dynamic global vegetation model output (climate-based vegetation cover). The identified significant difference between these two datasets can be partially explained by the difference in the models themselves, but also by the fact that climate is not the sole factor responsible for vegetation change. Sensitivity analysis of HUMLAND showed that the intensity of anthropogenic vegetation modification mainly depended on three factors: the number of groups present, their preferences for vegetation openness around campsites, and the size of an area impacted by humans. Overall, both climate and human activities had strong impacts on vegetation openness during the study period. Our modelling results support the hypothesis that European ecosystems were strongly shaped by human activities already in the Mesolithic.

Germanium (Ge) is a critical raw material used in high-technology industry (i.e., optical industry) applications, and it is predominantly concentrated in coals and Zn-rich deposits. Previous studies on Zn-rich deposits have documented a correlation between Ge enrichment and the Cu, Ag, and/or Pb-Mn contents in the sphalerite crystal lattice. In this study, we observed Ge-rich nanoparticles hosted in Cu-poor sphalerite from the Banbianjie Zn-Ge deposit (>800 t graded at ∼100 ppm Ge), located in southwest China. Laser-ablation−inductively coupled plasma−mass spectroscopy (LA-ICP-MS) analyses revealed that sphalerite contains very heterogeneous Ge contents (172−1553 ppm). Germanium contents showed positive correlations with Fe, Mn, and Pb contents and negative correlations with Cd contents. Higher Ge contents were detected in the darker zones, whereas the lighter zones showed systematically low Ge contents and were enriched in Cd. Using transmission electron microscopy (TEM), Zn-Ge-Pb-S nanoparticles were identified in the darker zones of sphalerite. These nanoparticles exhibited Ge/Pb ratios (0.48−1.96) very similar to those measured in sphalerite (0.36−2.04), suggesting that Ge could be essentially hosted within the nanoparticles. We propose that the amounts of Zn-Ge-Pb-S nanoparticles are related to a self-organization model induced by rapid crystal growth. This self-organization processes may control the fluctuations of element concentrations in the boundary layer. This study highlights the importance of studying the nanoscale expression of critical elements to understand their incorporation mechanisms into natural materials.

Understanding what controls global leaf type variation in trees is crucial for comprehending their role in terrestrial ecosystems, including carbon, water and nutrient dynamics. Yet our understanding of the factors influencing forest leaf types remains incomplete, leaving us uncertain about the global proportions of needle-leaved, broadleaved, evergreen and deciduous trees. To address these gaps, we conducted a global, ground-sourced assessment of forest leaf-type variation by integrating forest inventory data with comprehensive leaf form (broadleaf vs needle-leaf) and habit (evergreen vs deciduous) records. We found that global variation in leaf habit is primarily driven by isothermality and soil characteristics, while leaf form is predominantly driven by temperature. Given these relationships, we estimate that 38% of global tree individuals are needle-leaved evergreen, 29% are broadleaved evergreen, 27% are broadleaved deciduous and 5% are needle-leaved deciduous. The aboveground biomass distribution among these tree types is approximately 21% (126.4 Gt), 54% (335.7 Gt), 22% (136.2 Gt) and 3% (18.7 Gt), respectively. We further project that, depending on future emissions pathways, 17–34% of forested areas will experience climate conditions by the end of the century that currently support a different forest type, highlighting the intensification of climatic stress on existing forests. By quantifying the distribution of tree leaf types and their corresponding biomass, and identifying regions where climate change will exert greatest pressure on current leaf types, our results can help improve predictions of future terrestrial ecosystem functioning and carbon cycling.

Brickman; Jerome Maller; Chantal Meslin; Jie Chen; Danielle Vienneau; Kees de Hoogh; Bénédicte Jacquemin; Claudine Berr; Marion Mortamais;International audience; Background: Growing epidemiological evidence suggests an adverse relationship between exposure to air pollutants and cognitive health, and this could be related to the effect of air pollution on vascular health.Objective: We aim to evaluate the association between air pollution exposure and a magnetic resonance imaging (MRI) marker of cerebral vascular burden, white matter hyperintensities (WMH).Methods: This cross-sectional analysis used data from the French Three-City Montpellier study. Randomly selected participants 65-80 years of age underwent an MRI examination to estimate their total and regional cerebral WMH volumes. Exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), and black carbon (BC) at the participants' residential address during the 5 years before the MRI examination was estimated with land use regression models. Multinomial and binomial logistic regression assessed the associations between exposure to each of the three pollutants and categories of total and lobar WMH volumes.Results: Participants' (n=582) median age at MRI was 70.7 years [interquartile range (IQR): 6.1], and 52% (n=300) were women. Median exposure to air pollution over the 5 years before MRI acquisition was 24.3 (IQR: 1.7) μg/m3 for PM2.5, 48.9 (14.6) μg/m3 for NO2, and 2.66 (0.60) 10−5/m for BC. We found no significant association between exposure to the three air pollutants and total WMH volume. We found that PM2.5 exposure was significantly associated with higher risk of temporal lobe WMH burden [odds ratio (OR) for an IQR increase=1.82(95% confidence interval: 1.41, 2.36) for the second volume tercile, 2.04 (1.59, 2.61) for the third volume tercile, reference: first volume tercile]. Associations for other regional WMH volumes were inconsistent.Conclusion: In this population-based study in older adults, PM2.5 exposure was associated with increased risk of high WMH volume in the temporal lobe, strengthening the evidence on PM2.5 adverse effect on the brain. Further studies looking at different markers of cerebrovascular damage are still needed to document the potential vascular effects of air pollution.

Castelle; D. Buscombe; S. Vitousek;AbstractSatellite remote sensing is becoming a widely used monitoring technique in coastal sciences. Yet, no benchmarking studies exist that compare the performance of popular satellite-derived shoreline mapping algorithms against standardized sets of inputs and validation data. Here we present a new benchmarking framework to evaluate the accuracy of shoreline change observations extracted from publicly available satellite imagery (Landsat and Sentinel-2). Accuracy and precision of five established shoreline mapping algorithms are evaluated at four sandy beaches with varying geologic and oceanographic conditions. Comparisons against long-term in situ beach surveys reveal that all algorithms provide horizontal accuracy on the order of 10 m at microtidal sites. However, accuracy deteriorates as the tidal range increases, to more than 20 m for a high-energy macrotidal beach (Truc Vert, France) with complex foreshore morphology. The goal of this open-source, collaborative benchmarking framework is to identify areas of improvement for present algorithms, while providing a stepping stone for testing future developments, and ensuring reproducibility of methods across various research groups and applications.

Houghton; Brent Sohngen;Unmanaged land areas are not included in current national reports on greenhouse gas emissions for the Paris Agreement. Here, we argue that carbon dioxide fluxes from all forest land need to be recorded in order to help tracking progress towards global climate targets. Under the Kyoto Protocol, countries agreed that greenhouse emissions and removals from land activities should count towards their climate targets only if arising from direct human-induced effects. However, the Intergovernmental Panel on Climate Change (IPCC) noted that direct human-induced effects on land are deeply intertwined with changing environmental drivers such as increased atmospheric carbon dioxide (CO 2) concentration (indirect effects) and that they cannot be separated through the methods used in national greenhouse gas inventories. Therefore, to facilitate national greenhouse gas inventory reporting, the IPCC Guidelines 1 adopted the concept of 'managed land'-land where countries decide that human interventions and practices have been applied to perform production, ecological or social functions-as a pragmatic proxy for anthropogenic effects. Greenhouse gas fluxes are thus defined as all those occurring on managed land, whether they stem from either direct human-induced effects or from changing environmental drivers. Countries thus only need to estimate and report to the United Nations Framework Convention on Climate Change (UNFCCC) the greenhouse gas fluxes on managed land. While it is good practice to report the area of unmanaged lands in the greenhouse gas inventory, there is no obligation to report greenhouse gas fluxes from these lands. In other words, countries have so far assumed that they have no control over, and are therefore not liable for the greenhouse gas fluxes on unmanaged lands. The current separation, in which only part of the land is reported, makes it impossible to establish a direct link between the fluxes reported to UNFCCC and the observed growth rates of greenhouse gases in the atmosphere. This narrow focus on managed land also contributes to the discrepancy between national greenhouse gas inventories and the estimates for the global net terrestrial carbon flux established by the scientific community (Fig. 1). To a large degree, the mind-boggling range in estimates shown in Fig. 1 results from different ways to define the term 'anthropogenic'. In addition, managed and unmanaged land is delineated in diverse ways, depending whether the delineation is performed by land use researchers, as part of countries' greenhouse gas reporting 2 , through remote sensing approaches or via atmospheric inversion approaches. Furthermore, the definition of managed land as a proxy for anthropogenic emissions and removals is not homogeneous across countries. At present, large areas of unmanaged forest are reported by Brazil, Canada and Russia, while for most developing countries it is often unclear if they consider all forest as managed or not 3. Even less information is available for unmanaged non-forest area, which might include grassland and wetlands.

Vallet; L. Vallet; M. Schwartz; P. Ciais; D. van Wees; A. de Truchis; F. Mouillot;The frequency and intensity of summer droughts and heat waves in Western Europe have been increasing, raising concerns about the emergence of fire hazard in less fire-prone areas. This exposure of old-growth forests hosting unadapted tree species may cause disproportionately large biomass losses compared to those observed in frequently burned Mediterranean ecosystems. Therefore, analyzing fire seasons from the perspective of exposed burned areas alone is insufficient; we must also consider impacts on biomass loss. In this study, we focus on the exceptional 2022 summer fire season in France and use very high-resolution (10 m) satellite data to calculate the burned area, tree height at the national level, and subsequent ecological impact based on biomass loss during fires. Our high-resolution semi-automated detection estimated 42 520 ha of burned area, compared to the 66 393 ha estimated by the European automated remote sensing detection system (EFFIS), including 48 330 ha actually occurring in forests. We show that Mediterranean forests had a lower biomass loss than in previous years, whereas there was a drastic increase in burned area and biomass loss over the Atlantic pine forests and temperate forests. High biomass losses in the Atlantic pine forests were driven by the large burned area (28 600 ha in 2022 vs. 494 ha yr−1 in 2006–2021 period) but mitigated by a low exposed tree biomass mostly located on intensive management areas. Conversely, biomass loss in temperate forests was abnormally high due to both a 15-fold increase in burned area compared to previous years (3300 ha in 2022 vs. 216 ha in the 2006–2021 period) and a high tree biomass of the forests which burned. Overall, the biomass loss (i.e., wood biomass dry weight) was 0.25 Mt in Mediterranean forests and shrublands, 1.74 Mt in the Atlantic pine forest, and 0.57 Mt in temperate forests, amounting to a total loss of 2.553 Mt, equivalent to a 17 % increase of the average natural mortality of all French forests, as reported by the national inventory. A comparison of biomass loss between our estimates and global biomass/burned areas data indicates that higher resolution improves the identification of small fire patches, reduces the commission errors with a more accurate delineation of the perimeter of each fire, and increases the biomass affected. This study paves the way for the development of low-latency, high-accuracy assessment of biomass losses and fire patch contours to deliver a more informative impact-based characterization of each fire year.; La fréquence et l'intensité des sécheresses estivales et des vagues de chaleur en Europe occidentale ont augmenté, suscitant des inquiétudes quant à l'émergence d'un risque d'incendie dans des zones moins sujettes aux incendies. L'exposition de forêts anciennes abritant des espèces d'arbres non adaptées peut entraîner des pertes de biomasse disproportionnées par rapport à celles observées dans les écosystèmes méditerranéens fréquemment incendiés. Par conséquent, l'analyse des saisons des incendies du seul point de vue des zones brûlées exposées est insuffisante ; nous devons également prendre en compte les impacts sur la perte de biomasse. Dans cette étude, nous nous concentrons sur la saison exceptionnelle des incendies de l'été 2022 en France et utilisons des données satellitaires à très haute résolution (10 m) pour calculer la surface brûlée, la hauteur des arbres au niveau national et l'impact écologique subséquent basé sur la perte de biomasse pendant les incendies. Notre détection semi-automatique à haute résolution a permis d'estimer 42 520 ha de surface brûlée, contre 66 393 ha estimés par le système européen automatisé de détection par télédétection (EFFIS), dont 48 330 ha se trouvant effectivement dans des forêts. Nous montrons que les forêts méditerranéennes ont subi une perte de biomasse plus faible que les années précédentes, alors qu'il y a eu une augmentation drastique de la surface brûlée et de la perte de biomasse dans les forêts de pins atlantiques et les forêts tempérées. Les pertes élevées de biomasse dans les forêts de pins atlantiques sont dues à l'étendue des zones brûlées (28 600 ha en 2022 contre 494 ha par an au cours de la période 2006-2021), mais elles sont atténuées par une faible biomasse d'arbres exposés, situés pour la plupart dans des zones de gestion intensive. Inversement, la perte de biomasse dans les forêts tempérées a été anormalement élevée en raison à la fois d'une multiplication par 15 de la superficie brûlée par rapport aux années précédentes (3 300 ha en 2022 contre 216 ha au cours de la période 2006-2021) et d'une biomasse arborée élevée dans les forêts qui ont brûlé. Globalement, la perte de biomasse (c'est-à-dire le poids sec de la biomasse du bois) a été de 0,25 Mt dans les forêts et les arbustes méditerranéens, de 1,74 Mt dans la forêt de pins atlantiques et de 0,57 Mt dans les forêts tempérées, soit une perte totale de 2,553 Mt, ce qui équivaut à une augmentation de 17 % de la mortalité naturelle moyenne de toutes les forêts françaises, telle qu'elle est indiquée dans l'inventaire national. Une comparaison de la perte de biomasse entre nos estimations et les données globales de biomasse/surfaces brûlées indique qu'une résolution plus élevée améliore l'identification des petites taches de feu, réduit les erreurs de commission grâce à une délimitation plus précise du périmètre de chaque feu, et augmente la biomasse affectée. Cette étude ouvre la voie au développement d'une évaluation à faible latence et à haute précision des pertes de biomasse et des contours des taches de feu afin de fournir une caractérisation plus informative basée sur l'impact de chaque année d'incendie.

In practical terms, this means increasing the botanical diversity and delaying mowing of the grasslands to favor fauna diversity and associated ecosystem services. However, it is unknown whether these feeding practices alter rumen microbiota and its association with methane (CH 4) emission, a potent greenhouse gas. The objective of this study was to assess CH 4 emission and rumen microbiota of several dairy breeds fed agroecology diets. Three dairy cattle breeds (Holstein Friesian, Groninger Blaarkop and Jersey) (N = 10 for each breed) were fed three grass silage-based diets that included a proportion of a control silage, an experimental silage composed of late mown grass, and an experimental silage composed of diverse botanical species. Cows were fed for 13 weeks with gradual adjustment of the proportion of each silage. Rumen fluid was sampled during the weeks that corresponded to the highest proportion of each silage in the diet. Rumen microbiota was characterized through 16 s rRNA gene amplicon sequencing for its richness and diversity, as well as its compositions according to diet type and breed. Production performances and CH 4 emission were also measured. Methane production (g/d) was similar between the control and the agroecological diets. Cows fed the experimental diets had a different rumen microbiota composition than cows fed control diet. The cows fed the agroecological diets presented reduced relative abundances of Rumminoccocaeae, and higher relative abundances of Chirstensenellaceae and Methanobrevibacter than cows fed the control diet. Besides, the cows fed the agroecological diets presented a richer (P < 0.01) and more diverse (P < 0.01) rumen microbiota. Overall, this study highlights how feeding practices that comply with agroecology principles, and applied under practical conditions, shaped the rumen microbiota of specialized and dual-purpose cattle breeds.
