Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...

野生动物学报, 2012 近年来,威海一直致力于生态城市的建设。物种多样性是生态城市的重要指标,而在物种多样性中,城市鸟类多样性起着重要的作用。本文调查了冬季威海7个斑块（2个校园和5个典型生活小区）的鸟类多样性,对其物种多样性指数以及均匀度指数进行分析,得出山东大学校园和哈尔滨工业大学校园的鸟类多样性高于5个小区斑块,而且2个校园斑块的均匀度在7个斑块中也处于较高水平。另外,结合实际情况,文章从绿化面积、城市栖息地的空间异质性、生境破碎化程度以及人为干扰4个方面对城市鸟类丰富度与多样性的影响因素做出讨论 ...

Assessing differences among elasmobranch nurseries to aid conservation based on a genomics framework
Conservation Biology, EarlyView.Abstract Elasmobranch nurseries often differ in environmental conditions, demographics, and use patterns. These differences affect the distribution of genetic variation among nurseries. However, conservation and management strategies often fail to account for such differences because they are difficult to characterize.

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）

Emerging applications of large language models in ecology and conservation science
Conservation Biology, EarlyView.Abstract Large language models (LLMs) mark a major development in artificial intelligence, with potentially transformative implications for ecology and conservation science. Built on advanced deep‐learning architectures, these models can support a wide range of tasks. We reviewed emerging applications of LLMs, drawing on the wider scientific literature

Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.
