“…In agreement with the pattern of vascular plants on the QTP reported by Yan et al [28], and given our investigation sites were located on the northwest to the southeast part of the plateau as well as at high-latitude, we found that the mean of species richness was only approximately ten. Besides, we observed a strong correlation between species richness (SR) and phylogenetic diversity (Faith's PD), which is consistent with previous studies on woody plants in China [48], vascular plants in dry sandy heathlands [49], and shrubs in Mediterranean-type regions [50]. This congruency might be the product of evolution and ecological processes-the highly symmetrical phylogenies, lower species richness and high spatial autocorrelation all result in the strong SR-PD correlation [51].…”

Unravelling the patterns, potential processes and mechanisms underlying biodiversity has always been a crucial issue in community ecology. It is also a necessary first step for any conservation and restoration to better adapt fragile ecosystems to a changing climate. However, little is known regarding the structure and maintenance of plant communities in typical high-altitude wetlands. Here, we made a comprehensive analysis of the diversity and composition of wetland plant communities based on the distribution of plants near the shorelines of 19 lakes across the Qinghai-Tibetan Plateau. The latitude, mean annual temperature (MAT) and mean annual precipitation (MAP), along with the edaphic properties, were the dominant predictors affecting the taxonomic and phylogenetic α-diversity. Besides diversification, ecological drift, mixing with weak dispersal and weak selection shaped the community composition of wetland plants in our study. The latitude and MAP predictors, although modest, showed an impact on the community structure.

“…Therefore, conservation actions for tropical and subtropical floras are urgently needed to halt biodiversity loss under future warming. However, the existing protected areas (PA) in southern China are sporadic and the coverage of these PAs is only about half of the average level in China (Xu et al 2017, Cai et al 2021. Therefore, our study calls for the establishment of more PAs or expansion of the existing PAs in southern China, especially in the Yunnan-Guizhou Plateau and the Nanling Mountains.…”

Towards an understanding of the latitudinal patterns in thermal tolerance and vulnerability of woody plants under climate warming

Predicting spatial patterns in thermal tolerance and vulnerability of species under climate warming remains a challenge. Current knowledge is mainly from experiment‐based thermal physiology of limited numbers of ectotherms, yet large‐scale evaluations on plants remain elusive. Here, using distribution maps with spatial resolutions of 20 × 20 km for 5628 woody species in China, we propose a novel approach, i.e. thermal distribution curves, to describe species' realized thermal niches and then estimate their thermal tolerance and warming risks under projected climate warming in 2050s and 2070s. We find that species' vulnerability and potential local extinction risks within grid cells decrease with latitude and increase with aridity due to narrow thermal tolerance of species located at low latitudes and arid regions. Over 90% of species could still tolerate future warming in most areas, indicating relatively optimistic expectation of potential local extinctions. Our study presents a new framework to quantify climate warming impacts on a large number of species without sufficient physiological information and provides fundamental references for conservation planning under climate change.

“…We suggest that the dynamics of HNIs should be monitored and evaluated regularly. Besides, to achieve a more comprehensive understanding, it is also suitable and needed to evaluate the HNIs from other profiles, such as different taxa and levels of biodiversity or conservation status (Cai et al, 2020; Su et al, 2021).…”

Understanding the global patterns of land sharing-sparing between humans and wildlife is essential for pragmatic conservation implementation, yet analytical foundations and indicator-based assessments are still lacking. By integrating distributions of 30,664 terrestrial vertebrates and human pressures, we provide a series of spatial explicit Human-Nature Indices (HNIs) before classifying the global lands into four categories. We found that the Co-occurring (C) regions, where lands are shared by humans and wildlife, are not insignificant (16.91% of global land). For land-sparing, the Diversity-intact (D) and the Anthropic (A) regions account for 45.64% and 1.41% of the land, respectively. The patterns of HNIs, varying considerably among taxonomic groups, are determined mainly by the expansion of human-dominated land use. Land sharing and sparing could work as complementary strategies to support biodiversity and human development toward ambitious and pragmatic 30 by 30 goals. Our results highlight that those regions should adopt different conservation strategies according to their sharing-sparing patterns and distribution of protected areas.
