Silberberg; M.M. Mialon; B. Meunier; I. Veissier;International audience; High-energy diets increase the risk of Sub-Acute Ruminal Acidosis (SARA) inruminants. The behaviour of ruminants is modified under SARA however the impact onbehaviour of a high-energy diet and those of SARA per se are often confounded. Weaimed at distinguishing the effects of the diet and of SARA on cow behaviour. We fed28 Holstein cows a low-starch diet (low starch diet, 10.5% starch) or a high-starch diet(high starch diet, 31.5% starch). Control cows (n = 14) received the low starch diet for60 days, Challenge cows (n = 14) received the same diet except for a 2-week periodduring which they received the high starch diet and the 10 preceding days to ensurethe transition between diets. We monitored ruminal pH and activity of cows thanks tosensors, dry matter intake (DMI), and milk yield of each cow on a daily basis. TheSARA status was defined according to the relative decrease in ruminal pH and to pHvariability. High starch diet induced SARA more often than low starch diet (81% dayswhen cows received high starch diet vs. 8% when they received low starch diet. Highstarch diet also decreased milk yield and made cows spending less time eating buteating more quickly (Challenge vs. Control cows during the challenge period: milkyield, 20.0 vs. 18.2 L/d; % time spent eating, 22.5 vs. 27.6; eating rate, 77.1 vs. 69.6 gDMI/min; P (diet x period) 0.50). In conclusion, an increase ineating rate, especially combined with a decrease in milk yield should alert farmers tothe risk of ruminal acidosis.

Pardalos;International audience; Highlights: • AI in weed management potentials for transforming agricultural ecosystems. • AI influence in economic, social, technological, and environmental dimensions. • AI's role in enhancing food safety by reducing pesticides residues. • Digital literacy as a crucial enabler empowering stakeholders to use AI effectively.Abstract: In the face of increasing agricultural demands and environmental concerns, the effective management of weeds presents a pressing challenge in modern agriculture. Weeds not only compete with crops for resources but also pose threats to food safety and agricultural sustainability through the indiscriminate use of herbicides, which can lead to environmental contamination and herbicide-resistant weed populations. Artificial Intelligence (AI) has ushered in a paradigm shift in agriculture, particularly in the domain of weed management. AI's utilization in this domain extends beyond mere innovation, offering precise and eco-friendly solutions for the identification and control of weeds, thereby addressing critical agricultural challenges. This article aims to examine the application of AI in weed management in the context of weed detection and the increasing impact of deep learning techniques in the agricultural sector. Through an assessment of research articles, this study identifies critical factors influencing the adoption and implementation of AI in weed management. These criteria encompass factors of AI adoption (food safety, increased effectiveness, and eco-friendliness through herbicides reduction), AI implementation factors (capture technology, training datasets, AI models, and outcomes and accuracy), ancillary technologies (IoT, UAV, field robots, and herbicides), and the related impact of AI methods adoption (economic, social, technological, and environmental). Of the 5821 documents found, 99 full-text articles were assessed, and 68 were included in this study. The review highlights AI's role in enhancing food safety by reducing herbicide residues, increasing effectiveness in weed control strategies, and promoting eco-friendliness through judicious herbicide use. It underscores the importance of capture technology, training datasets, AI models, and accuracy metrics in AI implementation, emphasizing their synergy in revolutionizing weed management practices. Ancillary technologies, such as IoT, UAVs, field robots, and AI-enhanced herbicides, complement AI's capabilities, offering holistic and data-driven approaches to weed control. Additionally, the adoption of AI methods influences economic, social, technological, and environmental dimensions of agriculture. Last but not least, digital literacy emerges as a crucial enabler, empowering stakeholders to navigate AI technologies effectively and contribute to the sustainable transformation of weed management practices in agriculture.

Societal Impact Statement Vanilla is one of the most valuable spices in the world. In Madagascar and La Réunion, the world's leading producers, vanilla is of great economic and cultural importance. Like all orchids, vanilla plants associate with mycorrhizal fungi in their roots forming mutualistic associations that allow them to grow and thrive. Understanding the diversity of mycorrhizal fungi adapted to vanilla cultivation, particularly in the Indian Ocean islands where they have never previously been studied, is becoming a necessity for maintaining vanilla crops in these regions in the face of climate change and the emergence of new pathogens. Summary The vanilla orchid (Vanilla spp.) is one of the most valuable cultivated plants worldwide. As with all orchids, vanillas form mycorrhizal associations with fungi in their roots, but their fungal partners have not been investigated outside their native geographic range in Central America. We investigated the whole fungal and mycorrhizal associations in cultivated vanilla (Vanilla planifolia) by sequencing the fungal ITS-2 marker in the terrestrial and aerial roots using a metabarcoding approach. We selected plants cultivated in three conditions (i.e., cultivation under shade house, in openfield, or in the understory) in one locality of La Réunion island (Indian Ocean) and tested for a possible effect of cultivation practices on fungal communities. Cultivated vanillas in La Réunion mainly associate with Tulasnellaceae (75 OTUs) and Ceratobasidiaceae (8 OTUs). Among the seven most abundant Tulasnellaceae, six are similar to fungi detected in the roots of cultivated vanillas in Central America or in the roots of native orchids in La Réunion. Cultivation practices impacted both total fungal and mycorrhizal community compositions with no clear effect on fungal richness. Notably, Tulasnellaceae and Ceratobasidiaceae were scarce in aerial roots, except in the traditional cultivation in the forest understory. These results shed light on the geographical origins of mycorrhizal fungi of cultivated vanillas in La Réunion and show that they form a pool of both locally and globally distributed fungal partners. These mycorrhizal communities vary according to cultivation practices, and their potential roles in plant nutrition and resistance against pathogens await further attention.

This article presents a novel centrality-driven gateway designation framework for the improved real-time performance of low-power wireless sensor networks (WSNs) at system design time. We target time-synchronized channel hopping (TSCH) WSNs with centralized network management and multiple gateways with the objective of enhancing traffic schedulability by design. To this aim, we propose a novel network centrality metric termed minimal-overlap centrality that characterizes the overall number of path overlaps between all the active flows in the network when a given node is selected as gateway. The metric is used as a gateway designation criterion to elect as a gateway the node leading to the minimal number of overlaps. The method is then extended to multiple gateways with the aid of the unsupervised learning method of spectral clustering. Concretely, after a given number of clusters are identified, we use the new metric at each cluster to designate as cluster gateway the node with the least overall number of overlaps. Extensive simulations with random topologies under centralized earliest-deadline-first (EDF) scheduling and shortest-path routing suggest our approach is dominant over traditional centrality metrics from social network analysis, namely, eigenvector, closeness, betweenness, and degree. Notably, our approach reduces by up to 40% the worst-case end-to-end deadline misses achieved by classical centrality-driven gateway designation methods.

International audience; Abstract Fallen fruits provide important feeding and breeding substrates for insects such as Drosophilidae and can be a potential trophic reservoir when usual host fruits become scarce. Recently, two invasive fruit fly species, Drosophila suzukii and Chymomyza amoena , have become established in Europe and are expected to alter existing Drosophilidae communities. In this study, carried out between September 2021 and April 2022 in northern France, we aimed to disentangle the relative roles of microclimatic, landscape and local factors driving the diversity of the Drosophilidae community in decaying fruit across seasons. Minimum site temperature during the week preceding sampling and the proportion of rotten fruit tissue had the strongest positive influence on Drosophilidae abundance and species richness. Drosophilidae abundance also increased with urbanisation (portion of building cover) around the sampled trees. Decaying apples were important breeding sites for C. amoena across seasons, but provided a suboptimal substrate for D. suzukii , which was only present in late summer. This study sheds light on the important role of unharvested fallen crop fruit in maintaining the diversity of an insect family that is generally overlooked in field studies. It also emphasises the importance of considering multiple scales and factors when studying the interactions between invasive species, native species and their shared trophic resources. Finally, our data highlight the importance of the Drosophilidae community in recycling agricultural waste.; Resumé Les fruits tombés au sol et en décomposition constituent des ressources alimentaires ou des sites de reproduction pour les insectes, tels que les drosophiles. Ces fruits ‘abandonnés’ peuvent donc devenir des réservoirs trophiques pour certaines espèces lorsque leurs fruits hôtes privilégiés deviennent rares. Récemment, deux espèces de drosophiles invasives, Drosophila suzukii et Chymomyza ameona , se sont établies en Europe et leur présence est susceptible d'impacter les communautés natives de drosophiles. Notre étude a été réalisée entre Septembre 2021 et Avril 2022 dans le nord de la France. L'objectif était de déterminer les influences respectives des facteurs microclimatiques, paysagers et locaux sur les variations de la diversité des communautés de drosophiles présentes dans des pommes en décomposition sur le sol au cours des saisons. L'abondance et la diversité des espèces de Drosophilidae étaient majoritairement et positivement influencées par la température minimale des sites durant la semaine précédant l'échantillonnage mais aussi par la proportion de tissus en décomposition dans le fruit. L'abondance des drosophiles a également augmenté avec l'urbanisation (la densité de bâtiments dans le paysage) autour des arbres échantillonnés. Les pommes en décomposition constituaient des sites de reproduction important pour C. ameona à travers les saisons, mais ces fruits n'étaient qu'un substrat sous‐optimal pour D. suzukii , seulement présente à la fin de l'été. Cette étude met en évidence l'importance des fruits abandonnés au sol après la récolte, qui contribuent ainsi à maintenir la biodiversité des espèces de Drosophilidae, une famille d'insectes souvent négligée dans les études de terrain. Nos résultats témoignent également de l'intérêt de considérer plusieurs échelles et variables pour étudier les interactions entre les espèces invasives et natives, en lien avec les ressources qu'elles partagent. Enfin, cette étude met en lumière le rôle fondamental des communautés de Drosophilidae dans le recyclage des déchets issus de l'agriculture.

With the advent of new and cheap polarimetric sensors, this imaging modality is becoming accessible to a wider public for solving problems such as pose estimation, 3D reconstruction, underwater navigation, and depth estimation. However, we observe several limitations regarding the usage of this sensorial modality, as well as a lack of standards and publicly available tools to analyze polarization images. Furthermore, although polarization camera manufacturers usually provide acquisition tools to interface with their cameras, they rarely include processing algorithms that make use of the polarization information. In this paper, we review recent advances in applications that involve polarization imaging, including a comprehensive survey of recent advances on polarization for vision and robotics perception tasks. We also introduce a complete software toolkit that provides common standards to communicate with and process information from most of the existing micro-grid polarization cameras on the market. The toolkit also implements several image processing algorithms for this modality, and it is publicly available on GitHub: https://github.com/vibot-lab/Pola4all_JEI_2023.

Low-intensity management in these uneven-aged mountain forests therefore has limited effects on soil fungal community composition which is mainly driven by elevation and edaphic properties. Context Past and current human activities are known to affect forest biodiversity. However, the effects of former land use and forest management have been studied much more extensively on higher plants than on fungi. Aims Our objectives were to assess the effects of harvesting intensity, duration since last harvest and former land use on soil fungal communities in uneven-aged mountain high forests. Methods On the basis of historical land-use maps drawn between 1862 and 1864 and on historical forest management archives, we selected 62 sites in the French Alps with contrasting land-use histories (ancient forests, which were already forested on historical maps vs recent forests, which have recovered following abandonment of pastures) and different durations since last harvest (from 1 to over 50 years). We carried out soil sampling and assessed fungal diversity by metabarcoding analysis. We analysed soil fungal molecular operational taxonomic units (MOTU) diversity as a whole and for the main lifestyle groups (such as wood saprotrophic or ectomycorrhizal fungi) using multiple linear regressions on Shannon’s diversity index and fungal taxonomic composition using canonical correlation analysis. Results We found no significant effect of harvesting intensity, time since last harvest or land-use history on total fungal MOTU diversity, fungal lifestyle diversity or taxonomic composition. In contrast, we observed significant effects of elevation, pH, organic carbon and available phosphorus content on the taxonomic and functional composition of soil fungal communities. Conclusions The structure of soil fungal communities (i.e. diversity and species composition) was mainly determined by elevation and edaphic factors, indicating a high-context dependency, as previously found in similar studies. Our study in mountain forests shows that recent forests established on former pastures had no legacy effect on soil conditions and fungal communities, in contrast to previous results in lowland areas, where recent forests were mainly established on former cropland. Uneven-aged forest management had no effect on fungal diversity, in contrast to previous results observed in even-aged high forests.

Due to climate change, drought-induced forest dieback has become a major concern in temperate forests, including our study area, where oak is a key species. In order to better assess and adapt the actions needed to mitigate these impacts, access to accurate and regularly updated maps of forest health has become essential. In this context, the main objective of the study is to evaluate the interest of multispectral satellite time series for operational monitoring of forest dieback. Thanks to the in-situ data collected from 2017 to 2022 on about 2700 oak plots, a multiyear mapping of the analyzed region was performed using a supervised classification approach with the Random Forest algorithm. The results show that it is possible to detect oak dieback accurately (average overall accuracy = 80% and average balanced accuracy = 79%). More importantly, this study highlights the importance of measuring the temporal stability of the classification model in addition to standard cross-validation metrics. In this respect, the samples used for training are selected using data augmentation and balancing techniques to achieve better generalization over years. The learned model can also be used for predictive mapping of forest dieback in the coming years, for which the balanced accuracy is slightly reduced to about 70%. A feature analysis is also performed and shows that the shortwave infrared (SWIR) part of the spectrum is the most important for mapping forest dieback. In addition, using the red-edge portion of the spectrum can increase the stability of the model over time. We show that using only two vegetation indices based on continuum removal (CR) of the red edge (CRre) and shortwave infrared (CRswir) parts of the Sentinel-2 spectrum is sufficient to efficiently capture forest dieback. Overall, both in situ data and model predictions showed evidence of forest decline in many areas of the study region. Moreover, our results show that large areas of forest can decline over short periods of time, highlighting the interest of satellite data to provide timely and accurate information on forest status at large scales. This encourages the use and improvement of such approaches in the future.

The IEEE 802.11ax amendment extends it to support the 6 GHz band, 160 MHz bandwidth and bit-rates up to 9.6 Gbps. In this article, we evaluate the performance of Wi-Fi 6 compared to Wi-Fi 5 and Wi-Fi 4. We select 9 physical layers (PHYs) representing different Wi-Fi generations and we evaluate their performance in an industrial shipyard in the presence of high radio frequency interference and metallic obstructions. We deploy setup of a robotic station (STA) and a controller STA with three applications running in parallel: a robotic STA is sending a high throughput stream to a controller, a Robotic Operating System (ROS) application is sending time-critical control commands to the robotic STA, Precision Time Protocol (PTP) keeps synchronizing the clocks between both STAs. We evaluate the performance in terms of three Key Performance Indicators (KPIs): streaming throughput, IP-level delay using PTP, and Application-level delay of ROS control packets. The networks are run in: Short range Line of Sight (LoS), Medium range LoS, Long range None-LoS (NLoS), and Long range mixed settings. We note that depending on the PHY configuration, an older Wi-Fi generation may outperform Wi-Fi 6. We further observe trade-offs between the different PHYs: wide channel PHYs (e.g. 160 MHz) had best throughput reaching up to 900 Mbps while PHYs while 80 MHz or 20 MHz bandwidth achieved as low as 9 ms delay. This motivates further research in multi-PHY adaptation for KPIs specific to industrial robotics.

Silberberg; M.M. Mialon; B. Meunier; I. Veissier;International audience; High-energy diets increase the risk of Sub-Acute Ruminal Acidosis (SARA) inruminants. The behaviour of ruminants is modified under SARA however the impact onbehaviour of a high-energy diet and those of SARA per se are often confounded. Weaimed at distinguishing the effects of the diet and of SARA on cow behaviour. We fed28 Holstein cows a low-starch diet (low starch diet, 10.5% starch) or a high-starch diet(high starch diet, 31.5% starch). Control cows (n = 14) received the low starch diet for60 days, Challenge cows (n = 14) received the same diet except for a 2-week periodduring which they received the high starch diet and the 10 preceding days to ensurethe transition between diets. We monitored ruminal pH and activity of cows thanks tosensors, dry matter intake (DMI), and milk yield of each cow on a daily basis. TheSARA status was defined according to the relative decrease in ruminal pH and to pHvariability. High starch diet induced SARA more often than low starch diet (81% dayswhen cows received high starch diet vs. 8% when they received low starch diet. Highstarch diet also decreased milk yield and made cows spending less time eating buteating more quickly (Challenge vs. Control cows during the challenge period: milkyield, 20.0 vs. 18.2 L/d; % time spent eating, 22.5 vs. 27.6; eating rate, 77.1 vs. 69.6 gDMI/min; P (diet x period) 0.50). In conclusion, an increase ineating rate, especially combined with a decrease in milk yield should alert farmers tothe risk of ruminal acidosis.

Pardalos;International audience; Highlights: • AI in weed management potentials for transforming agricultural ecosystems. • AI influence in economic, social, technological, and environmental dimensions. • AI's role in enhancing food safety by reducing pesticides residues. • Digital literacy as a crucial enabler empowering stakeholders to use AI effectively.Abstract: In the face of increasing agricultural demands and environmental concerns, the effective management of weeds presents a pressing challenge in modern agriculture. Weeds not only compete with crops for resources but also pose threats to food safety and agricultural sustainability through the indiscriminate use of herbicides, which can lead to environmental contamination and herbicide-resistant weed populations. Artificial Intelligence (AI) has ushered in a paradigm shift in agriculture, particularly in the domain of weed management. AI's utilization in this domain extends beyond mere innovation, offering precise and eco-friendly solutions for the identification and control of weeds, thereby addressing critical agricultural challenges. This article aims to examine the application of AI in weed management in the context of weed detection and the increasing impact of deep learning techniques in the agricultural sector. Through an assessment of research articles, this study identifies critical factors influencing the adoption and implementation of AI in weed management. These criteria encompass factors of AI adoption (food safety, increased effectiveness, and eco-friendliness through herbicides reduction), AI implementation factors (capture technology, training datasets, AI models, and outcomes and accuracy), ancillary technologies (IoT, UAV, field robots, and herbicides), and the related impact of AI methods adoption (economic, social, technological, and environmental). Of the 5821 documents found, 99 full-text articles were assessed, and 68 were included in this study. The review highlights AI's role in enhancing food safety by reducing herbicide residues, increasing effectiveness in weed control strategies, and promoting eco-friendliness through judicious herbicide use. It underscores the importance of capture technology, training datasets, AI models, and accuracy metrics in AI implementation, emphasizing their synergy in revolutionizing weed management practices. Ancillary technologies, such as IoT, UAVs, field robots, and AI-enhanced herbicides, complement AI's capabilities, offering holistic and data-driven approaches to weed control. Additionally, the adoption of AI methods influences economic, social, technological, and environmental dimensions of agriculture. Last but not least, digital literacy emerges as a crucial enabler, empowering stakeholders to navigate AI technologies effectively and contribute to the sustainable transformation of weed management practices in agriculture.

Societal Impact Statement Vanilla is one of the most valuable spices in the world. In Madagascar and La Réunion, the world's leading producers, vanilla is of great economic and cultural importance. Like all orchids, vanilla plants associate with mycorrhizal fungi in their roots forming mutualistic associations that allow them to grow and thrive. Understanding the diversity of mycorrhizal fungi adapted to vanilla cultivation, particularly in the Indian Ocean islands where they have never previously been studied, is becoming a necessity for maintaining vanilla crops in these regions in the face of climate change and the emergence of new pathogens. Summary The vanilla orchid (Vanilla spp.) is one of the most valuable cultivated plants worldwide. As with all orchids, vanillas form mycorrhizal associations with fungi in their roots, but their fungal partners have not been investigated outside their native geographic range in Central America. We investigated the whole fungal and mycorrhizal associations in cultivated vanilla (Vanilla planifolia) by sequencing the fungal ITS-2 marker in the terrestrial and aerial roots using a metabarcoding approach. We selected plants cultivated in three conditions (i.e., cultivation under shade house, in openfield, or in the understory) in one locality of La Réunion island (Indian Ocean) and tested for a possible effect of cultivation practices on fungal communities. Cultivated vanillas in La Réunion mainly associate with Tulasnellaceae (75 OTUs) and Ceratobasidiaceae (8 OTUs). Among the seven most abundant Tulasnellaceae, six are similar to fungi detected in the roots of cultivated vanillas in Central America or in the roots of native orchids in La Réunion. Cultivation practices impacted both total fungal and mycorrhizal community compositions with no clear effect on fungal richness. Notably, Tulasnellaceae and Ceratobasidiaceae were scarce in aerial roots, except in the traditional cultivation in the forest understory. These results shed light on the geographical origins of mycorrhizal fungi of cultivated vanillas in La Réunion and show that they form a pool of both locally and globally distributed fungal partners. These mycorrhizal communities vary according to cultivation practices, and their potential roles in plant nutrition and resistance against pathogens await further attention.

This article presents a novel centrality-driven gateway designation framework for the improved real-time performance of low-power wireless sensor networks (WSNs) at system design time. We target time-synchronized channel hopping (TSCH) WSNs with centralized network management and multiple gateways with the objective of enhancing traffic schedulability by design. To this aim, we propose a novel network centrality metric termed minimal-overlap centrality that characterizes the overall number of path overlaps between all the active flows in the network when a given node is selected as gateway. The metric is used as a gateway designation criterion to elect as a gateway the node leading to the minimal number of overlaps. The method is then extended to multiple gateways with the aid of the unsupervised learning method of spectral clustering. Concretely, after a given number of clusters are identified, we use the new metric at each cluster to designate as cluster gateway the node with the least overall number of overlaps. Extensive simulations with random topologies under centralized earliest-deadline-first (EDF) scheduling and shortest-path routing suggest our approach is dominant over traditional centrality metrics from social network analysis, namely, eigenvector, closeness, betweenness, and degree. Notably, our approach reduces by up to 40% the worst-case end-to-end deadline misses achieved by classical centrality-driven gateway designation methods.

International audience; Abstract Fallen fruits provide important feeding and breeding substrates for insects such as Drosophilidae and can be a potential trophic reservoir when usual host fruits become scarce. Recently, two invasive fruit fly species, Drosophila suzukii and Chymomyza amoena , have become established in Europe and are expected to alter existing Drosophilidae communities. In this study, carried out between September 2021 and April 2022 in northern France, we aimed to disentangle the relative roles of microclimatic, landscape and local factors driving the diversity of the Drosophilidae community in decaying fruit across seasons. Minimum site temperature during the week preceding sampling and the proportion of rotten fruit tissue had the strongest positive influence on Drosophilidae abundance and species richness. Drosophilidae abundance also increased with urbanisation (portion of building cover) around the sampled trees. Decaying apples were important breeding sites for C. amoena across seasons, but provided a suboptimal substrate for D. suzukii , which was only present in late summer. This study sheds light on the important role of unharvested fallen crop fruit in maintaining the diversity of an insect family that is generally overlooked in field studies. It also emphasises the importance of considering multiple scales and factors when studying the interactions between invasive species, native species and their shared trophic resources. Finally, our data highlight the importance of the Drosophilidae community in recycling agricultural waste.; Resumé Les fruits tombés au sol et en décomposition constituent des ressources alimentaires ou des sites de reproduction pour les insectes, tels que les drosophiles. Ces fruits ‘abandonnés’ peuvent donc devenir des réservoirs trophiques pour certaines espèces lorsque leurs fruits hôtes privilégiés deviennent rares. Récemment, deux espèces de drosophiles invasives, Drosophila suzukii et Chymomyza ameona , se sont établies en Europe et leur présence est susceptible d'impacter les communautés natives de drosophiles. Notre étude a été réalisée entre Septembre 2021 et Avril 2022 dans le nord de la France. L'objectif était de déterminer les influences respectives des facteurs microclimatiques, paysagers et locaux sur les variations de la diversité des communautés de drosophiles présentes dans des pommes en décomposition sur le sol au cours des saisons. L'abondance et la diversité des espèces de Drosophilidae étaient majoritairement et positivement influencées par la température minimale des sites durant la semaine précédant l'échantillonnage mais aussi par la proportion de tissus en décomposition dans le fruit. L'abondance des drosophiles a également augmenté avec l'urbanisation (la densité de bâtiments dans le paysage) autour des arbres échantillonnés. Les pommes en décomposition constituaient des sites de reproduction important pour C. ameona à travers les saisons, mais ces fruits n'étaient qu'un substrat sous‐optimal pour D. suzukii , seulement présente à la fin de l'été. Cette étude met en évidence l'importance des fruits abandonnés au sol après la récolte, qui contribuent ainsi à maintenir la biodiversité des espèces de Drosophilidae, une famille d'insectes souvent négligée dans les études de terrain. Nos résultats témoignent également de l'intérêt de considérer plusieurs échelles et variables pour étudier les interactions entre les espèces invasives et natives, en lien avec les ressources qu'elles partagent. Enfin, cette étude met en lumière le rôle fondamental des communautés de Drosophilidae dans le recyclage des déchets issus de l'agriculture.

With the advent of new and cheap polarimetric sensors, this imaging modality is becoming accessible to a wider public for solving problems such as pose estimation, 3D reconstruction, underwater navigation, and depth estimation. However, we observe several limitations regarding the usage of this sensorial modality, as well as a lack of standards and publicly available tools to analyze polarization images. Furthermore, although polarization camera manufacturers usually provide acquisition tools to interface with their cameras, they rarely include processing algorithms that make use of the polarization information. In this paper, we review recent advances in applications that involve polarization imaging, including a comprehensive survey of recent advances on polarization for vision and robotics perception tasks. We also introduce a complete software toolkit that provides common standards to communicate with and process information from most of the existing micro-grid polarization cameras on the market. The toolkit also implements several image processing algorithms for this modality, and it is publicly available on GitHub: https://github.com/vibot-lab/Pola4all_JEI_2023.

Low-intensity management in these uneven-aged mountain forests therefore has limited effects on soil fungal community composition which is mainly driven by elevation and edaphic properties. Context Past and current human activities are known to affect forest biodiversity. However, the effects of former land use and forest management have been studied much more extensively on higher plants than on fungi. Aims Our objectives were to assess the effects of harvesting intensity, duration since last harvest and former land use on soil fungal communities in uneven-aged mountain high forests. Methods On the basis of historical land-use maps drawn between 1862 and 1864 and on historical forest management archives, we selected 62 sites in the French Alps with contrasting land-use histories (ancient forests, which were already forested on historical maps vs recent forests, which have recovered following abandonment of pastures) and different durations since last harvest (from 1 to over 50 years). We carried out soil sampling and assessed fungal diversity by metabarcoding analysis. We analysed soil fungal molecular operational taxonomic units (MOTU) diversity as a whole and for the main lifestyle groups (such as wood saprotrophic or ectomycorrhizal fungi) using multiple linear regressions on Shannon’s diversity index and fungal taxonomic composition using canonical correlation analysis. Results We found no significant effect of harvesting intensity, time since last harvest or land-use history on total fungal MOTU diversity, fungal lifestyle diversity or taxonomic composition. In contrast, we observed significant effects of elevation, pH, organic carbon and available phosphorus content on the taxonomic and functional composition of soil fungal communities. Conclusions The structure of soil fungal communities (i.e. diversity and species composition) was mainly determined by elevation and edaphic factors, indicating a high-context dependency, as previously found in similar studies. Our study in mountain forests shows that recent forests established on former pastures had no legacy effect on soil conditions and fungal communities, in contrast to previous results in lowland areas, where recent forests were mainly established on former cropland. Uneven-aged forest management had no effect on fungal diversity, in contrast to previous results observed in even-aged high forests.

Due to climate change, drought-induced forest dieback has become a major concern in temperate forests, including our study area, where oak is a key species. In order to better assess and adapt the actions needed to mitigate these impacts, access to accurate and regularly updated maps of forest health has become essential. In this context, the main objective of the study is to evaluate the interest of multispectral satellite time series for operational monitoring of forest dieback. Thanks to the in-situ data collected from 2017 to 2022 on about 2700 oak plots, a multiyear mapping of the analyzed region was performed using a supervised classification approach with the Random Forest algorithm. The results show that it is possible to detect oak dieback accurately (average overall accuracy = 80% and average balanced accuracy = 79%). More importantly, this study highlights the importance of measuring the temporal stability of the classification model in addition to standard cross-validation metrics. In this respect, the samples used for training are selected using data augmentation and balancing techniques to achieve better generalization over years. The learned model can also be used for predictive mapping of forest dieback in the coming years, for which the balanced accuracy is slightly reduced to about 70%. A feature analysis is also performed and shows that the shortwave infrared (SWIR) part of the spectrum is the most important for mapping forest dieback. In addition, using the red-edge portion of the spectrum can increase the stability of the model over time. We show that using only two vegetation indices based on continuum removal (CR) of the red edge (CRre) and shortwave infrared (CRswir) parts of the Sentinel-2 spectrum is sufficient to efficiently capture forest dieback. Overall, both in situ data and model predictions showed evidence of forest decline in many areas of the study region. Moreover, our results show that large areas of forest can decline over short periods of time, highlighting the interest of satellite data to provide timely and accurate information on forest status at large scales. This encourages the use and improvement of such approaches in the future.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2024 FrancePublisher:Elsevier BV Mina Rady; Oana Iova; Hervé Rivano; Angeliki Deligianni; Leonidas Drikos;International audience; Wi-Fi is a standard off-the-shelf solution for industrial robotics. The IEEE 802.11ax amendment extends it to support the 6 GHz band, 160 MHz bandwidth and bit-rates up to 9.6 Gbps. In this article, we evaluate the performance of Wi-Fi 6 compared to Wi-Fi 5 and Wi-Fi 4. We select 9 physical layers (PHYs) representing different Wi-Fi generations and we evaluate their performance in an industrial shipyard in the presence of high radio frequency interference and metallic obstructions. We deploy setup of a robotic station (STA) and a controller STA with three applications running in parallel: a robotic STA is sending a high throughput stream to a controller, a Robotic Operating System (ROS) application is sending time-critical control commands to the robotic STA, Precision Time Protocol (PTP) keeps synchronizing the clocks between both STAs. We evaluate the performance in terms of three Key Performance Indicators (KPIs): streaming throughput, IP-level delay using PTP, and Application-level delay of ROS control packets. The networks are run in: Short range Line of Sight (LoS), Medium range LoS, Long range None-LoS (NLoS), and Long range mixed settings. We note that depending on the PHY configuration, an older Wi-Fi generation may outperform Wi-Fi 6. We further observe trade-offs between the different PHYs: wide channel PHYs (e.g. 160 MHz) had best throughput reaching up to 900 Mbps while PHYs while 80 MHz or 20 MHz bandwidth achieved as low as 9 ms delay. This motivates further research in multi-PHY adaptation for KPIs specific to industrial robotics.
