Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

云南沾益中度退化天坑草地植物群落水平空间分布特征 [PDF]
, 2018 规模最为宏大的地表负地形——喀斯特天坑不仅是世界罕见的地质奇观,圈闭化地形而形成的独特生境更是探索植物物种多样性及其空间分布特征最为理想的地域。以云南沾益天坑群中的中度退化天坑——\"巴家陷塘\"坑底草地植物群落为研究对象,通过α多样性指数与β相似性系数的应用,对\"巴家陷塘\"中度退化天坑坑底草地植物群落物种多样性的水平空间分布特征展开探讨,并对其近邻退化漏斗和\"大毛寺\"原生天坑坑外草地植物群落的相似性进行对比分析,研究结果发现:(1 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Microeukaryotic community structure and diversity in Xiamen offshore waters and Shenhu Bay, Fujian [PDF]
, 2015 微型真核浮游生物是海洋生态系统的重要组成成分，同时在海洋经典食物链和微食物网中发挥重要作用。该类群个体较小，对环境变化较为敏感，作为生产者、消费者和分解者的微型真核浮游生物在海洋生态系统的生物地球化学过程和生态健康评价等方面有着重要意义。本研究选择厦门岛近海海域和福建省泉州市深沪湾为例，对目标海区进行微型真核浮游生物样品的釆集，运用变性梯度凝胶电泳（DGGE）、克隆测序和高通量测序技术方法对微型真核浮游生物群落组成和多样性进行研究，分析其时空分布和群落结构特征 ...

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...
