Study on the Systematic Conservation Planning based conservation pattern of marine biodiversity in Xiamen [PDF]
, 2015 随着经济发展、人口增加和城市化程度的加深，人类活动正在导致其赖以生存和发展的海洋生物多样性的减少甚至丧失。建立海洋保护区是目前保护海洋生物多样性的重要途径。然而传统海洋保护区规划往往仅考虑保护少数物种，而缺乏对海洋生物多样性所依托的海岸生境的保护的考虑；很多保护区范围是人为划定而缺少对保护成本的考虑，导致付出很高的成本却没有达到生物多样性保护的目标，有些地方甚至由于成本过高导致保护区形同虚设。研究平衡生物多样性保护和社会经济发展 ...

Wildlife Letters, EarlyView.Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

An Integrated Research on Marine Biodiversity Conservation at the core of Regional Ocean Governance [PDF]
, 2016 海洋生态系统是人类赖以生存和发展的重要物质和文化基础。随着人类社会经济活动的范围和强度不断拓展和加深，全球海洋生物多样性及其持续向人类提供生态系统服务的功能面临着日益严峻的破坏和威胁。如何加强和完善海洋生态系统养护和管理，实现海洋生物多样性可持续保护和发展，是全球共同面临的重要课题，同时也考验着人类在自然-社会生态系统互动中形成怎样的关系和响应策略问题。海洋生物多样性保护作为人类共同关切事项所具有的公共产品属性要求全球、区域和国家多层面采取集体行动来共同应对。在此背景下 ...

Wildlife Letters, EarlyView.Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Shuitu Baochi Xuebao, 2003 试验采用碳素利用(BIOLOG)及磷酸酯脂肪酸(PLFA)法,研究了8种供试红壤微生物群落的功能多样性和结构多样性。两种方法均表明土地利用方式能显著影响微生物的多样性。采用磷酸酯脂肪酸法无需培养就能鉴别土壤微生物的组成结构,试验表明总PLFA含量与微生物生物量呈显著相关。碳素利用法的研究结果显示,茶叶园土中微生物对各类碳源的利用能力均很低,呈现出非常独特的微生物功能多样性。

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological communities are stressed by rapid and complex anthropogenic changes, threatening the persistence of biotic interactions and ecosystem functioning. Plant–pollinator communities, for instance, undergo structural transformations as a result of land‐use change ...

Distribution Pattern of Taxonomic Diversity of Fish Community in Four Typical Mangrove Areas, China [PDF]
, 2016 红树林区不仅能为许多海生和陆生生物提供栖息地和食物，还是许多鱼类的育幼场和产卵场，因此红树林区生物多样性成为当今生态学研究热点之一。过去对红树林区鱼类群落的研究多采用传统生物多样性指数，然而传统生物多样性指数在实际运用过程具有过多注重物种丰富度、未考虑物种在分类学上的差异等缺陷。分类多样性指数既考虑了群落中物种数量和均匀程度，也考虑了物种分类地位和生态学上的差异，更全面更有说服力。 为全面了解中国红树林区鱼类物种多样性分布格局，本研究选取福建漳江口、广西茅尾海、广西山口、海南东寨港四个典型的红树林区 ...
