野生动物学报, 2005 野生动物保护一般有三种形式:就地保护,迁地保护,离体保存。目前,国内外就地保护的主要形式,就是建立自然保护区。自然保护区就如同一个个保存着物种资源的岛屿,处在人类干扰的汪洋大海中。按照岛屿生物地理学原理,自然保护区的面积当然是越大越好 ...

Exploring gaps, biases, and research priorities in the evidence for reptile conservation actions
Conservation Biology, EarlyView.Abstract With over 21% of reptile species threatened with extinction, there is an urgent need to ensure conservation actions to protect and restore populations are informed by relevant, reliable evidence. We examined the geographic and taxonomic distribution of 707 studies that tested the effects of actions to conserve reptiles synthesized in ...

Guangtongxin yanjiu, 2007 针对弹性分组环（Resilient Packet Ring,RPR）技术中的源路由和环回两种保护倒换机制的不足,文章提出了一种新型保护倒换机制———源节点保护倒换,并对这种保护倒换机制的性能进行了分析。源节点保护倒换克服了源路由保护倒换存在的严重的丢包现象,避免了包失序问题,同时减小了环回保护倒换产生的较大时延和不必要的带宽浪费,充分提高了RPR中保护倒换的性能。

Assessing limits of sustainable seed harvest in wild plant populations
Conservation Biology, EarlyView.Abstract Seed harvesting from wild plant populations is key for ecological restoration, but it may threaten the persistence of the source populations. Consequently, several countries have set guidelines limiting the proportions of harvestable seeds. However, these guidelines are inconsistent and lack a solid empirical basis.

A global indicator of species recovery
Conservation Biology, EarlyView.Abstract Monitoring progress toward meeting global biodiversity goals involves several indicators, including, at the species level, the International Union for Conservation of Nature (IUCN) Red List Index (RLI) and the Living Planet Index (LPI). However, at present, there is no indicator specifically for tracking species recovery, despite this being ...

Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, EarlyView.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

Predictions of southern migration timing in coastal sharks under future ocean warming
Conservation Biology, EarlyView.Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

野生动物学报, 2007 本文论述了铜壁关自然保护区的现状、存在问题及发展对策。铜壁关保护区地理位置特殊,区系复杂,物种丰富,特有种多,对我国生物多样性保护具有十分重要的意义。但保护区至今尚未升为国家级,保护区级别低、缺乏专业技术人员、管理体制不顺等问题困扰着保护区的进一步发展。建议成立保护区管理局,理顺管理体制,扩大保护区面积,尽快升为国家级保护区,进行更为严格的管理。
