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 ...

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Elephant barrier behaviors in response to conflict mitigation fences
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Human–wildlife conflict is a major conservation issue, particularly in lower income countries, where it affects marginalized people and leads to the extirpation of threatened species. Managers increasingly use fences to reduce this conflict but lack evidence on the effectiveness of these barriers, especially on whether this reduces the number ...

Taxonomy, distribution and comparative study of thermal tolerance in Nipponacmea limpets along China coast [PDF]
, 2015 作为生物圈最脆弱的系统之一，潮间带生态系统是研究全球变化对群落动态影响的理想系统。全球变化带来的环境变化如温度升高、海水酸化和海平面升高等可影响生物行为、生理以及进化适应，从而改变潮间带生物的种群动态和群落结构。而面对环境变化，物种间由于适应能力的差异，会出现“胜利者”和“失败者”。背尖贝（GenusNipponacmea）是常见潮间带生物，广泛分布于我国沿海中-高潮间带岩石上。本研究利用DNA条形码研究中国沿岸背尖贝的分类、系统发育以及地理分布格局，并测定不同温度下背尖贝属间生理和分子适应的差异 ...
