ABSTRACT Aim Wildlife populations are continuing to decrease worldwide. Understanding the ranking and distribution of drivers species declines is crucial enable targeted actions counteract major threats. However, few studies have assessed relative importance geographic threats biodiversity in China, even for high‐profile groups such as birds mammals. Therefore, this study aims rank map threat mammals which could provide novel insight into conservation China. Location Methods A database different 147 threatened bird 176 terrestrial mammal was obtained from China's Red List Biodiversity published 2021. We collated information on categories aiming classify, used Bray–Curtis dissimilarity index examine correlations occurring simultaneously, compared habitat In addition, we conducted analyses between orders traits (body mass clutch/litter sizes). Results The results showed that most common were loss, hunting, human disturbance, agriculture, pollution logging, while disturbance livestock farming or ranching. These patterns, some frequently co‐occur syndromes. Forests primary species, formed by larger with small clutch litter sizes more likely be threatened. Main Conclusions highlight key areas conservation. Furthermore, focusing clusters co‐occurring may effective way aid recovery needed counter ongoing population many groups. should not limited protection regions where at risk multiple significant threats, but also include maintenance restoration native forests strategic planning afforestation through planted forests.

Ambitious biodiversity goals to protect 30% or more of the Earth’s surface by 2030 (30x30) require strategic near-term targets. To define areas that must be protected prevent most likely and imminent extinctions, we propose Conservation Imperatives—16,825 unprotected sites spanning ~164 Mha terrestrial realm harbor rare threatened species. We estimate protecting Imperatives would cost approximately US$169 billion (90% probability: US$146—US$228 billion). Globally, 38% 16,825 are either adjacent within 2.5 km an existing area, potentially reducing land acquisition management costs. These should prioritized for conservation action over next 5 years as part a broader strategy expand global area network. The expansion between 2018 2023 incorporated only 7% harboring range-limited species, highlighting renewed urgency conserve these habitats. Permanently 0.74% found in tropics, where concentrated, could majority predicted extinctions once adequately resourced. this from US$29 US$46 per year years. Multiple approaches will required meet long-term protection goals: providing rights titles Indigenous Peoples Local Communities (IPLCs) conserving traditional lands, government designation new on federal state purchase leasing privately held lands.

Proactively identifying where land conversion might occur is critical to targeted and effective conservation planning. Previous efforts map future habitat loss have largely focused on forested systems been limited in their consideration of drivers loss. We developed a 1-km resolution, global pressure from multiple drivers, referred as the index (CPI). The CPI combines past rates anthropogenic change, measured by temporal human modification maps, with suitability maps for potential expansion large-scale development. thus offers new way measure cumulative gradient opposed categorical cover change. find that nearly 23% across 200 countries relatively high pressure, potentially impacting over 460 million ha intact natural lands. illustrate how this information can be used identify areas proactive avoid ensure national commitments under Kunming-Montreal Global Biodiversity Paris Agreement Climate Frameworks are upheld.

Abstract The Langbian Plateau, a biodiversity hotspot in the southern Annamites of Viet Nam, has undergone extensive hunting pressure. However, limited information on effects overexploitation current status and community composition wildlife hinders effective conservation efforts, including implementation targeted patrols to reduce snaring. In this study, we conducted camera‐trapping survey across consisting broadleaf evergreen coniferous habitat mosaic. We recorded 46 ground‐dwelling mammals birds, several threatened Annamite endemics. Using multi‐species Royle‐Nichols model landscape covariates, found higher richness forest located more remote less rugged areas. then used species responses covariates predict distribution identify high‐priority areas for conservation. Furthermore, constructed diversity profiles that indicated compared forest. Finally, dissimilarity index assess level defaunation, revealing 16% had been lost, with levels defaunation larger‐sized species. Our findings provide insights into status, distribution, occurrence mammal bird communities can help stakeholders design strategies protect existing populations.

ABSTRACT Motivation Population density is a fundamental parameter in ecology and conservation, taxonomic geographic patterns of population have been an important focus macroecological research. However, data are time‐consuming costly to collect, so their availability limited. Leveraging decades research, TetraDENSITY 1.0 was developed as global repository containing over 18,000 estimates for > 2100 terrestrial vertebrate species, aiding researchers investigating density, its intrinsic extrinsic drivers, developing predictive models. Here we present substantially expanded version the database, which now includes marine tetrapods encompasses 54,300 3717 species associated with error geographical coordinates when available, hence enabling meta‐analytical approaches better spatial matching environmental conditions. Main Types Variables Contained errors, time location collection, information, estimation method. Spatial Location Global. Time Period Grain 1925–2024. Major Taxa Level Measurement Amphibia, Reptilia, Aves Mammalia. Estimates reported at level. Software Format .csv.

Approaches that allow capitalizing on local population estimates to derive global with associated uncertainty are urgently needed, especially for naturally rare species of conservation concern. Here we used published density predict large-scale patterns and two large felids, the leopard tiger. We modelled (n=392) tiger (n=547) as a function environmental anthropogenic variables, while controlling differences in sampling method area, time data collection, spatial autocorrelation, subspecies political protection. Bayesian inference generate distribution plausible sizes. Both showed higher densities high productivity areas, being more abundant precipitation, level terrain roughness agricultural areas low croplands roughness. Primary roads negative effect both species. Secondary was but lower Livestock biomass humped relationship tigers' densities. Temporal trends average were tiger, experiencing an decline 34% (IQR: 11% − 53%). In contrast, trend leopards marginal, yet uncertain, increase recent years 21% -5% 57%). predicted estimate 261,636 (IQR = 146,768 461,512) 5,201 tigers 2,596 10,460). Large-scale models rely unstructured can contribute our understanding ecology, produce robust size assessment inform planning. At same time, around these highlights limited knowledge available which should be accounted assessments.
