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.

, 1984 行为治疗在医疗实践中起着突出作用,并且是行为医学的核心内容。那么,行为治疗的理论基础是什么?它又有哪些方法呢? 首先谈谈什么是行为?行为是人们对其所处环境的反应,或是人们在其所处环境中做什么。一般来说,人有两种行为:(1)反应行为,或称不随意反应或自主反应。例如,见到食物流唾液、听到巨声而惊恐,运动后出汗等。另外,对躯体疾病产生的恐惧和焦虑的情绪反应也能在某种紧张情况下以同样的自主反应形式产生。(2)操作行为,或称有目的反应。这种行为包括一个人在日常生活中产生的各种行为,如走路、讲话、服药、抓搔 ...

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

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.

Risks of concealing environmental degradation
Conservation Biology, EarlyView.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...
