Here, we developed a framework that uses water temperature forecasting as a tool to predict the migrations of Atlantic salmon (<i>Salmo salar</i>) and European eel (<i>Anguilla anguilla</i>) between freshwater and the sea. We used historical observations of lake water temperature and fish migrations from an internationally important long-term monitoring site (the Burrishoole catchment, Ireland) to generate daily probabilistic predictions (0%–100%) of when relatively large numbers of fish migrate. For this, we produced daily lake water temperature forecasts that extended up to 34 days into the future using Forecasting Lake and Reservoir Ecosystems (FLARE), an open-source ensemble-based forecasting system. We used this system to forecast lake water temperature conditions associated with percentile-based fish migrations. Two metrics, P66 and P95, were used to indicate days with migrations in excess of 66% and 95%, respectively, of the historical daily fish counts. The results were first validated against water temperature observations, with an overall root mean squared error (RMSE) of 0.97°C. Our forecasts outperformed two other possible water temperature forecasting approaches, using site climatology (1.36°C) and site persistence (1.19°C). The predictions for fish migrations performed better for the P66 metric than for the more extreme P95 metric based on the continuous ranked probability score (CRPS), and the best results were obtained for the salmon downstream migration. This forecasting approach with quantified uncertainty levels has the potential to assist decision making, especially in the face of increased risks for these species.

Our results suggest fire damage may prevent the critical timing in which peak physiological function overlaps with optimal growing conditions (e.g., moisture and nutrient availability). As a result, we suggest the degree of root and microbial damage should be assessed along with observed aboveground damage to more effectively predict tree recovery potential.

Using environmental DNA metabarcoding, we sampled rocky fish assemblages of the Cap Roux no-take marine reserve and the surrounding fished areas, covering several depth strata ranging from the surface to mesophotic depths. We found that protection, depth, and their interaction had a significant effect on fish diversity and assemblage composition. The vast majority of the 66 fish taxa identified in this study were detected inside the MPA. On the other hand, depth had a negative impact, with mesophotic reefs harboring the lowest diversity. Shallow protected locations were composed of rich fish assemblages, including targeted and threatened species that were rarely detected or even undetected outside the MPA and/or at mesophotic depths.

Regional assessments of the “State of Birds” are a vital means to prioritize data-driven conservation action by informing national and global policy. Such evaluations have traditionally relied on data derived from extensive, long-term, standardized surveys that require significant resources, limiting their feasibility to a few regions in the world. In the absence of such “structured” long-term datasets, “semi-structured” datasets have recently emerged as a promising alternative in other regions around the world. Semi-structured data are generated and uploaded by birdwatchers to citizen science platforms such as eBird. Such data contain inherent biases because birdwatchers are not required to adhere to a fixed protocol. An evaluation of the status of birds from semi-structured data is therefore a difficult task that requires careful curation of data and the use of robust statistical methods to reduce errors and biases. In this article, we present a methodology that was developed for this purpose and was applied to produce the comprehensive State of India's Birds (SoIB) 2023 report. SoIB 2023 assessed the status of 942 bird species in India by evaluating each species based on three metrics: (1) long-term change, (2) current annual trend, and (3) distribution range size. We found evidence that 204 species have declined in the long term and that 142 species are in current decline. Birds that have vertebrate or invertebrate diets have declined most rapidly in the long term, whereas those that feed on fruits and nectar have been stable. Birds that require grasslands have declined more rapidly than those that require other habitats, indicating that grasslands are an important ecosystem to prioritize conservation in India. We classify 178 species as high conservation priority and present and discuss important insights about India's birds that can guide research and conservation action in the region. We hope that the detailed methodology described here can act as a blueprint to produce State of Birds assessments from semi-structured citizen science datasets and springboard conservation action in many other regions where structured data are lacking but strong communities of birdwatchers exist.</p>","PeriodicalId":48930,"journal":{"name":"Ecosphere","volume":"16 7","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecs2.70290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We screened for potential nonlinearities in the spatial relationships between ecosystem indicators and environmental drivers over a 10-year period, and assessed commonalities in identified indicator–driver thresholds. To understand how the ecosystem indicators relate to commonly used metrics in single-species assessments, we also tested whether these relationships were consistent across species, species complexes, and functional groups. Gradient forests and generalized additive mixed models revealed detectable threshold relationships across five environmental drivers and six ecosystem indicators. Several indicators showed considerable overlap in threshold locations with common drivers, especially for rugosity (habitat complexity) and wave forcing. While some indicators comprising nested species, species complexes, and functional groups had comparable thresholds with a common driver, this was not always the case, highlighting the need for careful consideration when selecting indicators for management applications. We demonstrate the use of these thresholds in environmental drivers by evaluating them along a gradient of fish biomass. The use of multi-model inference to incorporate multiple statistical methods to define the relationship between an ecosystem indicator and driver offers a quantitative basis for ecosystem management.

In this study, we compared aboveground productivity of six <i>Populus</i> clones from three different taxa grown in monoclonal and mixed-clonal plots. The different mixture treatments were intended to experimentally test aboveground biomass response to contrasting levels of taxonomic diversity and functional diversity based on nitrogen use characteristics of <i>Populus</i> clones. We hypothesize that functional diversity would be more important than taxonomic diversity in increasing aboveground productivity of mixed-clonal plantings compared to monocultures. In addition, a subset of treatments was carried out on additional sites representing a productivity gradient in order to determine if the relationship between biodiversity and productivity in these systems diminished at more productive sites as suggested by the stress-gradient hypothesis. We found that functionally diverse mixtures of clones had greater yield of aboveground biomass than the average of their constituent monocultures, while more taxonomically diverse mixes of clones did not differ from the average of their constituent monocultures. However, when reestablished on sites with extremely high or low productivity, the best performing clone mixture also did not differ from the average of its constituent monocultures. Our results suggest that intimate clone mixtures of <i>Populus</i> have the potential to significantly increase productivity, but results vary by mixture and by site.

As such, it is inherently comprised of close interactions between humans and ecosystems and may provide unique insight into socio-ecological systems. Traditional harvest is generally accompanied by traditional resource management and directly influences ecological community dynamics, species reproduction and distribution, and competitive interactions. Meanwhile, ecological processes, seasonality, and natural disturbances influence human behaviors, decision making, activities, and well-being. As a result of this tight coupling, traditional harvest systems have the potential to serve as important laboratories for the study of ecological community dynamics. Resilience science, in particular, may benefit from greater appreciation of traditional harvest, wherein thresholds and bidirectional feedbacks may be more easily detected and modeled than in more diffuse socio-ecological systems. Additionally, because traditional harvest links to cultural heritage and traditional ecological knowledge, a greater understanding of these systems may facilitate efforts to support marginalized communities and social equity. We here discuss the value of traditional harvest research for science and society, highlighting as a case study the traditional harvest of Emory oak acorns by Western Apache Tribal Nations. We argue that traditional harvest systems carry important heuristic value but are often assumed to be rare or declining and are therefore relatively neglected by researchers, yet their persistence in modern agriculture-dominated systems exemplifies resilience.

This is particularly true in forest ecosystems where demographic patterns are controlled by many biotic and abiotic factors that may only be observed through repeated measures of tree (e.g., height, diameter, status), stand (e.g., tree density, litter depth), and site conditions (e.g., evidence of disturbance). Data from the United States Department of Agriculture Forest Service, Forest Inventory and Analysis Program (FIA), support a variety of research and reporting efforts in forest resources and ecology. Remeasurements of the same plots provide invaluable information about the temporal dynamics of forest ecosystems. However, changes in attributes between remeasurements, such as species identification code (SPCD), can impact a variety of forest measurements such as species richness, species range dynamics, and carbon estimates. Here, we linked over 12 million tree remeasurements from approximately 140,000 FIA plots to explore how SPCD changes can lead to differences in key indicators of forest dynamics. Our workflow identified &gt;114,000 trees with SPCD changes, with the frequency of SPCD changes highest in the southeastern United States. Two SPCD correction methods—adjusting a tree's SPCD based on either the earliest or the most recently recorded SPCD—led to species range centroids that differed by 0.3–24.5 km. Plot-level species richness varied by ±4 species between the two SPCD correction methods, but many plots (58%) had the same richness despite reassignment of individual trees to different SPCDs. Tree-level carbon stock estimates were correlated between the two SPCD correction methods, but some trees were more sensitive to changes when species-specific allometric model form, coefficients, and/or carbon fractions changed. However, population estimates of parameters such as carbon stocks per unit area were robust to SPCD corrections because trees with consistent SPCDs vastly outnumbered trees with SPCD changes. Our results illustrate that decisions on how to handle nuances in remeasurement data can have substantial implications on the biological and ecological conclusions drawn from large-scale, strategic-level inventories such as the national forest inventory in the United States.</p>","PeriodicalId":48930,"journal":{"name":"Ecosphere","volume":"16 7","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ecs2.70340","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
