Assessing and strengthening community‐based coastal governance
Conservation Biology, EarlyView.Abstract Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries

Psychometric framework for coexistence with large carnivores
Conservation Biology, EarlyView.Abstract Human–carnivore coexistence is essential for biodiversity conservation, yet measuring the attitudes and behaviors that support it remains methodologically challenging. We developed psychometric scales to assess willingness to coexist with carnivores and the underlying beliefs of this coexistence through an iterative expert elicitation process ...

野生动物学报, 2007 通过对代表厦门5种不同生境类型的8个样地进行鸟类调查,共记录到鸟类17目49科242种,占全国鸟类总种数的19.5%,占福建省鸟类总种数的44.7%。与全国鸟类组成相比,厦门鸣禽和涉禽的物种多样性相对比较丰富;比较5种代表性的生境鸟类多样性,农田物种多样性最丰富（Shannon-Wiener指数H′=5.549 63）,但是其科属多样性却最低(G-F指数DFG=0.53568);森林生境中科属多样性最高（G-F指数D（FG）=0.872282）,特别是科多样性显著高于其他生境（F指数DF=15.8911）

, 2021 毛茛科是真双子叶植物的基部类群之一,包含多种药用植物,具有较高的保护价值,但关于毛茛科物种多样性和谱系多样性大尺度格局及其影响因子的研究还比较匮乏,特别是以较高分辨率分布数据为基础的物种多样性格局研究尚未见报道。本文旨在:(1)建立欧亚大陆东部毛茛科植物分布数据库,估算不同生活型物种多样性和谱系多样性格局,并探究格局的形成机制。(2)分析毛茛科物种多样性和谱系多样性的相关关系,确定多样性热点地区,为毛茛科保护规划提供依据。根据中国、哈萨克斯坦、吉尔吉斯斯坦、塔吉克斯坦、土库曼斯坦、乌兹别克斯坦 ...

Modeling seed germination data to meet biodiversity conservation needs in the Mediterranean
Conservation Biology, EarlyView.Workflow to assess the availability and quality of germination data and assign species' thermal risk in the Mediterranean. (a) Assessment of data availability, including the phylogenetic distribution of the number of records (i.e. available germination data); (b) data quality assessment; and (c) assignment of climate risk categories for species that ...

Conservation Biology, EarlyView.Abstract Reversing ongoing biodiversity loss requires effectively managing anthropogenic threats. Although conservation actions can mitigate these threats, prioritizing and targeting such actions remain challenging because species respond differently depending on the nature of the threats and their biological traits.

Conservation Biology, EarlyView.Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

Structured decision‐making as a framework to incorporate social equity into conservation decisions
Conservation Biology, EarlyView.Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.
