Enhancing and protecting biodiversity is a prerequisite for achieving "harmony between human beings nature". With the disturbance of activities, landscape pattern constantly changing, changing flow species, information, energy within landscape, which in turn has significant impact on biodiversity. Therefore, based InVEST model, this paper obtained spatial distribution maintenance function established Chinese conservation empowerment network through GIS analysis. Based complex theory, dynamic evolution characteristics ecological structure were analyzed, relationship its topological terrestrial was revealed. The results show that: high south, southwest, northeast China low west, corridors also dense east sparse west. Over past 20 years, average grown slowly, community increased, more stable, connectivity stronger. weight degree, betweenness centrality, PageRank, eigenvector centrality significantly correlated with function, indicating that plays huge role maintaining By focusing building correlation sources, constructing to adjust connections, integrity important habitats will be gradually restored, so land can exert greater benefits.

Wet bias of summer precipitation in the northwestern Tibetan Plateau in ERA5 is linked to overestimated lower-level southerly wind over the plateau

Abstract The Tibetan Plateau (TP), also called the Third Pole, is considered to be “the world water tower”. northwestern TP (NWTP), which has an average elevation higher than 4800 m, arid region where summer precipitation largely overestimated by ERA5 global reanalysis product. We hypothesize that this wet bias mainly caused unrealistic lower-level winds trigger strong convection over region; it can reduced using a high-resolution regional climate model with large domain allows realistically representing interactions between Westerlies and Asian monsoons. Here, downscaling Weather Research Forecasting (WRF) driven was conducted (8°‒50° N, 65°‒125° E) at 9 km for period 1979‒2019 (WRF9km). Precipitation values from WRF9km were evaluated against satellite observations; compared ERA5, captured climatological NWTP much-reduced bias. overestimation excessive convective precipitation, likely linked vertical motions induced southerly wind.

Optimizing protected areas to boost the conservation of key protected wildlife in China

•From 1988 to 2021, the number of protected species almost doubled, area areas increased 2.4 times.•Over 92.8% are in areas, but some not effectively protected.•Amphibians and reptiles significant additions protection list, still least protected.•Another 10.0% China's land is needed as achieve target. To meet challenge biodiversity loss reach targets proposed Post-2020 Global Biodiversity Framework, Chinese government updated list national key wildlife 2021 has been continually expanding (PAs). However, status PAs remains unclear. In this study, we conducted a assessment suggested an optimization plan overcome these shortcomings. From by times, covering over species. Nonetheless, have less than 10% their habitat included PAs. Despite addition amphibians latest they fewest covered compared with birds mammals. fix gaps, systematically optimized current network adding another PAs, which resulted 37.6% coverage species' habitats addition, 26 priority were identified. Our research aimed identify gaps conservation policies suggest solutions facilitate planning China. general, updating optimizing PA networks essential applicable other countries facing loss.

Hidden hotspots of amphibian biodiversity in China

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(20)

Опубликована: Апрель 29, 2024

Identifying and protecting hotspots of endemism species richness is crucial for mitigating the global biodiversity crisis. However, our understanding spatial diversity patterns far from complete, which severely limits ability to conserve hotspots. Here, we report a comprehensive analysis amphibian in China, one most species-rich countries on Earth. Our study combines 20 y field surveys with new molecular analyses 521 described also identifies 100 potential cryptic species. We identify 10 each exceptional phylogenetic (based time-calibrated, species-level phylogeny Chinese amphibians). These encompass 59.6% China’s species, 49.0% 55.6% endemic China. Only four these correspond previously recognized The six include Nanling Mountains other mountain ranges South Among 186 hotspots, only 9.7% are well covered by protected areas (88.2%) exposed high human impacts. Five under very pressure urgent need protection. find that significantly related those but not identical.

Three-quarters of species’ ranges have not been covered by protected areas in global borders

Nature Communications, Год журнала: 2025, Номер 16(1)

Опубликована: Март 17, 2025

Borderlands are increasingly recognized as critically important for biodiversity conservation owing to their ecological significance and high political profile. However, the species ranges covered by protected areas influencing factors in transboundary still largely unknown worldwide. Here, based on distributional of 19,039 terrestrial vertebrates, we find that three-quarters species' global borders remain uncovered areas, particularly tropical Southeast Asia West Africa. The average area coverage is lower than non-transboundary after accounting geographical differences sampling efforts. We also observe increases with governance effectiveness, collaboration abilities, protection levels, sizes establishment years topographic complexity, but decreases human population density, development index, cropland expansion. Furthermore, simultaneously face threats ongoing challenges from climate change, land-use modification, alien invasion, proportions borderlands threatened changes higher elsewhere. All these findings demonstrate cross-border cooperation urgently needed achieve ambitious goal 2050. Transboundary critical refuges many species. this study reveals border regions facing greater change.
