Partly to counteract this loss, artificial wetlands have been created. While studies comparing animal communities between artificial and natural wetlands abound, research on their comparative ecological functions is scarce. In particular, vertebrate scavengers in aquatic ecosystems have been little studied despite their critical role in nutrient cycling. This study compared vertebrate scavenger assemblages and their consumption patterns in natural and artificial wetlands in Doñana, Spain, to evaluate the effects of wetland management (natural vs. artificial hydrology) across different seasons. We placed 120 carcasses (carp and chicken) in natural and artificial wetlands. We recorded 22 vertebrate scavenger species efficiently consuming 100 % of carrion in an average of less than two days, highlighting their role in nutrient recycling. Carrion of aquatic-origin was consumed faster and by a greater variety of species than that of terrestrial-origin, facilitating the transport of essential nutrients from water to land. Artificial wetlands exhibited higher efficiency in carrion removal (twice as fast as natural wetlands). However, they hosted less diverse assemblages, dominated by opportunistic and non-native species. This suggests that artificial wetlands are not replacing natural wetlands in terms of biodiversity, despite sustaining water levels and functions. Importantly, ‘kidnapping’ water for irrigation reduces the ability of natural wetlands to maintain ecological functions provided by scavengers. Urgent regulation of water abstraction from aquifers, especially for crop irrigation, is necessary to maintain minimum groundwater levels, preserving the functionality and ecological processes of this critical wetland complex.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"302 ","pages":"Article 110929"},"PeriodicalIF":4.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143145846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Many countries, including Brazil, have committed to restoring degraded landscapes at national and international levels. Brazil aims to restore twelve million hectares of degraded areas by 2030, which requires strategic decision-making to allocate resources effectively and balance biodiversity gains with societal benefits. Our modeling approach uses extensive biodiversity field data to identify priority areas for restoration across Brazil's diverse phytogeographic domains. By focusing on expanding native species habitats and enhancing connectivity, we aim to maximize ecological returns. Precisely, we pinpoint areas within each Brazilian phytogeographic domain with the greatest potential for habitat enhancement, including the Amazon's arc of deforestation, central Cerrado, the limits of Caatinga, Pampa, and Pantanal, and the coastal areas of the Atlantic Forest. Restoring 30 % of these areas—approximately 76 million hectares—could significantly benefit 11,028 species by increasing available habitat by up to 10 % and improving landscape functional connectivity by 60 %. Moreover, this restoration effort would capture up to 9.8 million tons of atmospheric carbon, contributing to global climate goals. As Brazil strives to meet national and international targets, we also advocate for economic incentives to support restoration practices within each phytogeographic domain. Integrating prioritization modeling into decision-making ensures optimal biodiversity and carbon stock outcomes to guide more effective restoration efforts.

Lighting also reduced crossing speed for badgers. We can conclude that, for some medium-sized wild mammals, ALAN triggers an avoidance behaviour that prevents them from crossing lit underpasses during certain seasons. This suggests that ALAN can act as a nightscape fragmentation, which is in line with previous studies on other taxa - as bats, insects, amphibians or eels.

However, anecdotal rapid variability in census size appear to be directly related to climate fluctuations, with long periods of drought in their winter breeding areas leading to large declines in migrating adults. These fluctuations are compounded by basic knowledge gaps regarding their genetic structure and dispersal mechanisms between winter breeding sites and alpine aestivation areas, which hinders conservation efforts and has impacts on threatened animal species that rely upon them. We use thousands of single nucleotide polymorphisms (SNPs) across 349 adult samples collected from 19 locations in southeastern Australia to determine genetic diversity and population structure. We then model wind patterns to determine if prevailing winds can explain measured genetic diversity and how long migrations might take to reach their aestivation sites and return to breeding grounds. We find that the moths have high levels of genetic diversity reflecting a large effective population size and that there is no significant population structuring (e.g., panmixia). The wind modelling indicates that wind patterns could explain random migratory patterns that lead to the observed panmixia, and that adult moths can migrate to, and from, alpine areas in as little as a single night from their winter breeding areas. Taking these data together, we suggest that conservation strategies need to occur range-wide and, in particular, protect breeding sites from land-use change in order to maintain moth migration rates that support the alpine ecosystem each year.</div></div>","PeriodicalId":55375,"journal":{"name":"Biological Conservation","volume":"302 ","pages":"Article 110993"},"PeriodicalIF":4.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143146601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A focus on occupancy can help to resolve some of the current complications arising from population monitoring of bees. We highlight the strengths of occupancy specifically in the context of wild bee monitoring, drawing from achievements of current monitoring programs of other taxa. We provide guidance for incorporating occupancy models into the design of current and future wild bee monitoring efforts and address important sampling biases to consider when monitoring bee populations.

Reconstructing how each factor has contributed to the historical trajectories of change in landscape suitability and connectivity, and which process is prevailing (loss or fragmentation) becomes pivotal to plan conservation and mitigation actions at local scale. By combining habitat suitability modelling and circuit- and graph-theory, we determined the temporal change in habitat suitability, functional connectivity, and spatial ecological network functionality for two Italian endemic amphibian taxa, an urodele, the Italian alpine newt, and an anuran, the Apennine yellow-bellied toad. The temporal trajectories for the alpine newt showed a gradual loss of suitability and functional connectivity, which is predicted to continue in the future, but with a steep drop in the network functionality already occurred in the last thirty-year period. This suggests that restoring connectivity may be the key for conservation actions of this endemism. Differently, in the Apennine yellow bellied toad, we found that the spatial network has already collapsed, while future projections highlighted a huge habitat loss issue. Conservation efforts for this species should therefore be focused on preserving current suitable areas and identifying possible translocation sites where to settle new populations.

Here we perform this validation using GPS tracking data collected from two migratory species during their movement over two count schemes: the globally endangered steppe eagle counted in Eilat, Israel, and the black kite, counted in Batumi, Georgia. We use tracking data to answer two questions: which populations are counted and what affects the probability that a given individual will be counted. Our results illustrate variability in the effectiveness of these two migratory bird counting schemes. Considering the goal of estimating population trends, we show that Eilat does not represent a good location for understanding population trends of steppe eagles, while Batumi appears to provide better information on demographic trends of black kites. We further present differences in annual and individual variability, evidence regarding the breeding area origins of the counted populations and effects of environmental factors on the raptors' routes and, consequently, on the probabilities of being counted. Beyond the direct implications of our results, this study provides an example of using telemetry data to parameterize inference from bird counts.

In particular, we focused on the ecology of and human relationships with a forest-dwelling parrot, the kākā (<em>Nestor meridionalis</em>) in Aotearoa New Zealand (AoNZ). We mapped Māori place names associated with kākā, overlaying these with the current reported distribution for kākā from iNaturalist. Names often occurred in clusters, with some of the largest clusters in areas where kākā are considered regionally extinct. We also examined street names, but most were modern subdivision assignations, and not informative of place-based biocultural relationships. Our searches of historical print archives (newspapers, magazines and journals) from 1842 to 1984 revealed a range of kākā-related material. Early references to kākā in magazines and journals (1861–2017) focused on ecology, reflecting mātauranga, but later references focused on legislation. Taken together, these sources show temporal changes in both geographical distribution and the nature of discussion in historical written sources around kākā and Māori relationships in AoNZ. We argue that partnering with local communities is also critical to understanding these relationships. We recommend that future translocation decision-making should incorporate the relationships and place-based knowledge of Indigenous and other local communities.
