Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

福建省牛姆林自然保护区常绿针阔叶混交林主要种群空间格局研究 [PDF]
, 2002 基于方差/均值比率法、x~2检验、集聚指数测度与检验、样方方差法等格局研究方法,对福建省牛姆林自然保护区常绿针阔叶混交林马尾松+拉氏栲(Pinus massonnina+Castanopsis lamontii)群落的7个主要乔木种群空间分布格局类型、格局规模与强度等特征研究结果显示,马尾松、拉氏栲、华南桂、木荷4个种群的格局属于随机分布格局;米椎、榄叶石栎和绒毛润楠3个种群的格局属于集聚分布格局,但其集聚强度均不高,依次为米椎>榄叶石栎>绒毛润楠 ...

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.

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 ...

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Water use characteristics of two Sonneratia mangrove species [PDF]
, 2017 红树林生长在热带、亚热带海岸潮间带。虽然海水充沛，但高盐度的海水使得土壤孔隙水水势极低，这在很大程度上限制了红树植物对水分的吸收，造成红树植物生理干旱的现象。红树植物大都采取了相同的水分利用策略，就是在节约用水的同时，最大程度地吸收水分。对红树植物的水分利用特征的研究是认识红树植物适应潮间带高盐及淹水胁迫的关键。本研究利用热扩散式茎流仪和微型气象站，在2015–2016年期间对深圳福田红树林自然保护区(22°31'N，114°0'E)内的两种同龄的海桑属红树植物，无瓣海桑 ...
