How much biotic nativeness matters across human demographic groups
Conservation Biology, EarlyView.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Conservation Biology, EarlyView.Abstract Human development is a driver of global change and a major threat to biodiversity. Protected areas maintain and support biodiversity, but outside stressors, such as climate change and land use change, can negatively influence natural resources within protected areas.

, 2018 结合坡面微地形变化,从土壤微生物群落多样性角度研究典型缓丘区不同坡位上土壤微生物群落特征,了解微地形生境下土壤微生物群落变化趋势.研究结果表明,土壤微生物群落培养的平均颜色变化率(AWCD)增长曲线呈现中坡位>坡顶>下坡位>上坡位>坡底的规律,中坡位土壤微生物群落代谢活性最高,坡底土壤微生物群落对基质的利用能力最低;在土壤微生物多样性指数比较中发现,除McIntosh均一度指数变化不显著外,其余土壤微生物多样性指数在不同坡位上存在显著差异.其中 ...

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Study on the marine protistan diversity in tropical and subtropical waters [PDF]
, 2017 原生生物是海洋浮游生物群落的主要组成部分，在海洋生态系统中占有十分重要的地位：真核藻类是海洋初级生产力的重要来源；原生动物通过摄食将物质和能量通过微食物网向更高营养层传递，原生动物摄食产生的颗粒有机碳通过物理沉降的方式埋藏于深海从而贡献于生物泵；原生动物通过改变浮游植物和细菌的群落组成，从而调节海洋生态系统平衡。因此，原生生物在海洋中扮演着十分重要的角色，是海洋中物质循环、能量流动和信息交流的重要纽带，在维持海洋生态系统平衡中发挥着不可替代的作用。近些年高通量测序技术的发展 ...

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.
