China is a country with one of the most species-rich reptile faunas in the ***,nearly a quarter of Chinese lizard species assessed by the China Biodiversity Red List are ***,to date,no study has explicitly examined the pattern and processes of extinction and threat in Chinese *** this study,we conducted the first comparative phylogenetic analysis of extinction risk in Chinese *** addressed the following 3 questions:(1)What is the pattern of extinction and threat in Chinese lizards?(2)Which species traits and extrinsic factors are related to their extinction risk?(3)How can we protect Chinese lizards based on our results?We collected data on 10 species traits(body size[BS],clutch size,geographic range size,activity time,reproductive mode,habitat specialization[HS],habitat use,leg development,maximum elevation,and elevation range)and 7 extrinsic factors(mean annual precipitation(MAP),mean annual temperature,mean annual solar insolation,normalized difference vegetation index(NDVI),human footprint,human population density,and human exploitation).After phylogenetic correction,these variables were used separately and in combination to assess their associations with extinction *** found that Chinese lizards with a small geographic range,large BS,high HS,and living in high MAP areas were vulnerable to *** priority should thus be given to species with the above extinction-prone traits so as to effectively protect Chinese *** future habitat destruction should also be a primary focus of management efforts because species with small range size and high HS are particularly vulnerable to habitat loss.

Most bird species remain poorly studied but threated status promotes research effort

Avian Research 2024年第4期15卷 413-421页

To halt biodiversity loss,threatened species are often selected as targets for conservation ***,whether most threatened species receive sufficient research effort remains *** research and public attention of threatened species would hinder the implementation of effective conservation ***,it is urgent to assess both research effort and species extinction risk simultaneously to provide critical information for targeted conservation ***,we evaluated research effort of extant bird species worldwide(n 10,904)by searching the number of all publications and those focused on conservation in Scopus database fo=r each species,and investigated key determinants of research *** found that although the median value of publications of threatened species was significantly higher than that of non-threatened species,47.4%of threatened species had less than 3 publications,and 73.8%had less than 10 publications,indicating low research effort of most threatened *** research effort was positively related to extinction risk,research effort was mainly associated with human-related variables,with birds described earlier and occurred in developed regions receiving higher research *** comparison,extinction risk was mainly associated with biological attributes,with large-sized and narrow-distributed species being more likely to be *** finding suggests that research effort of species can provide complementary information for current conservation strategies designed for threatened species,and we urge that many recently discovered and narrowly distributed species in less developed regions require more research and conservation attention.
