We conducted annual breeding season sampling for which we recorded native anuran species presences and abundances across different ponds. Additionally, we documented bullfrog invasion history and abundance and key environmental and climatic variables. We measured pond heterogeneity, which is influenced by variations in livestock grazing intensity and historical human use of native forests. We used generalized linear mixed models to predict richness and abundance of native anurans. We recorded 18 native amphibian species across the ponds, with declines in both richness and abundance as bullfrog invasion intensified. Models showed that ponds could lose up to 40% of amphibian species and 50% of amphibian abundance within 10 years of bullfrog invasion. Although environmental heterogeneity, particularly microhabitat edge diversity, attenuates these impacts, it is insufficient to halt this process. Among the most affected native anuran species were 3 highly aquatic-associated species. Our results highlight stressor effects across a broad spatiotemporal scale through an integrative approach, which we recommend for future research. Our findings underscore the threat of invasions to amphibian conservation.

Consistent approaches to classifying, describing, and assessing ecosystems can improve understanding of ecological processes, threats, and management. We explored how the International Union for Conservation of Nature (IUCN) Global Ecosystem Typology-a global classification framework based on ecosystem function-could support the development of a classification of ecosystems for the Tiwi Islands, Australia, by incorporating scientific information and Indigenous Tiwi knowledge to facilitate environmental management and conservation. We synthesized ecosystem information from previous research, field data, reports, and Tiwi knowledge authorities to develop a classification, descriptions, and a map of 14 terrestrial ecosystem types. These ecosystem types were defined and described based on ecological processes and were broader yet largely congruent with existing vegetation classifications. Including functional properties accounted for variation in the vegetation physiognomy exhibited by dynamic and disturbance-prone ecosystems, such as savannas. Because we considered Tiwi knowledge authorities and the IUCN Global Ecosystem Typology, our inventory included ecosystem types that were typically omitted from previous classifications, which should allow for more comprehensive assessments and management. Relating the new ecosystem typology to the IUCN Global Ecosystem Typology will facilitate comparisons among similar ecosystems, regarding, for example, effective threat abatement options. Describing the biota and processes opens new avenues for monitoring. More collaborative work is needed to explore how Western scientific ecosystem inventories operate alongside and in connection with management of Tiwi murrakupuni enacted by Tiwi people.

Although this rare conservation achievement has been widely celebrated in several recent cases, some other downlisting decisions have met with controversy. A primary role of the IUCN is to assess extinction risk. In this role, it must maintain its independence and not be influenced by the public outcry that may occur when a high-profile species is downlisted, even if well-established conservation programs may be disrupted or abandoned as a result. We explored the potential positive and negative consequences of downlisting for conservation efforts through case studies of the giant panda (Ailuropoda melanoleuca), red-crowned crane (Grus japonensis), saiga antelope (Saiga tatarica), and black-faced spoonbill (Platalea minor), which has recently been proposed for downlisting. Although downlisting can enable more effective use of limited resources, these cases highlight potential risks, including weakened legal backing, diversion of resources away from the species, and declining public and political support. The relatively unquestioned downlisting of the saiga antelope illustrates how early and inclusive engagement of local experts, assessors, donors, and other stakeholders can help ensure that decisions are effectively communicated and implemented without jeopardizing species recovery. The IUCN Green Status of Species assessment is a complementary tool to the IUCN Red List and offers a useful measure of conservation progress, which can help decision makers ensure that downlisting does not undermine long-term conservation efforts.</p>","PeriodicalId":10689,"journal":{"name":"Conservation Biology","volume":" ","pages":"e70103"},"PeriodicalIF":5.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144607734","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}

We conducted a meta-level analysis of equitable governance assessments conducted at 37 PCAs in 19 countries that form part of the new SAGE (Site-level Assessment of Governance and Equity) database.

In particular, evaluations of PCA decision-makers tended to be more positive than those of PCA users.

However, generalizations regarding the impacts of urbanization are still difficult due to the lack of studies encompassing the urban matrix. We examined the seed dispersal networks in natural forests and urban areas in Tenerife Island to explore the effects of urbanization on seed dispersal. For 1 year, we observed frugivory events and identified seeds in animal feces in natural forests and urban areas of the island. We also conducted transect surveys in each area to assess the abundance of fleshy fruits and frugivorous animals. We identified 150 interactions between 83 plant and 18 animal species in the forest and 89 interactions between 41 plant and 9 animal species in urban areas. The urban matrix supported half the species richness of fleshy-fruited plants and frugivorous animals relative to the forest. Urbanization simplified seed dispersal networks, reducing interaction diversity. Novel interactions dominated the urban seed dispersal network, where non-native plants were highly used by native frugivores, accounting for 61% of the interactions (vs. 15% in the forest). Eight frugivore species (42% of the frugivores) likely maintained the functional connectivity between these habitats, potentially facilitating the spread of non-native species from urban areas (where non-native species are more common) into the forests due to their generalist and flexible diets. Six frugivorous species (32%) completely avoided urban areas, which acted as barriers to dispersal, likely hindering the dispersal of many plants across urban landscapes. Our results underscore the importance of promoting the use of native plants as ornamentals, enhancing habitat connectivity between forests and urban areas, and preventing the introduction of non-native fleshy-fruited plants.

Using South American carnivore assemblages and fragmented tropical forests as a case study, we assessed the relative effect of structural connectivity on carnivore persistence in fragmented landscapes after accounting for PAC, and the efficacy of single-species connectivity approaches for protecting the habitat of multiple species. We applied a multiscale Bayesian modeling framework to camera-trapping data from 567 cameras in 23 landscapes in the Tumbesian region of Ecuador and Peru. We tested the landscape-scale effects of habitat amount, connectivity, human density, and protected area status on carnivore richness and mean occupancy and the fine-scale effects of forest cover, distance to roads, and hunting on carnivore site occupancy. In 41,861 camera days of sampling, we obtained 5267 independent detections of 12 carnivores across all landscapes. Connectivity, habitat amount, and PAC had a positive effect on carnivore richness, emphasizing that large and well-connected landscapes of natural habitat with greater PAC sustain more species-rich carnivore communities. Mean site occupancy across the carnivore community was positively associated with forest cover at the fine scale and connectivity at the landscape scale. This last relationship varied by species, with occupancy of forest-dependent mesocarnivores being most positively associated with higher connectivity.
