Analysis of Microbial Communities in Three Rounds of High-temperature Daqu Using Metagenomic Technology [PDF]
, 2023 Metagenomic sequencing technology was used to analyze the microbial community structures and functional composition in three rounds of Daqu. The results showed that the average assembly length of the 25 samples was 100.5 Mb, a total of 439 000 gene ...

How much biotic nativeness matters across human demographic groups
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Integrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

野生动物学报, 2008 作者分别于1998年、2005年和2007年春季采用样线法调查了胡列也吐湿地水鸟的种数和数量,得出这3 a水鸟群落多样性指数分别为3.66、3.85和3.33。研究了其变化并探讨原因,分析认为,因适当的补水机制导致2005年群落多样性和均匀度最高,湿地鸟类群落变丰富。2007年补水水位过深导致该生境内鸟类群落多样性下降。

Screening and Characteristics of Bacteria and Enzyme for Degradation of Malachite Green from Marine Sediment [PDF]
, 2015 孔雀石绿是一种三苯基甲烷类染料，广泛应用于水产、纺织、造纸等产业，导致水生环境化学需氧量(COD)和生物需氧量(BOD)大幅提高，阻挡光的透射，严重影响水生生物的生长，同时其毒性和致癌性也会通过食物链传递给人类及其他陆生生物。本研究以深海和红树林沉积物中微生物为研究对象，采用富集培养和宏基因组技术对可降解孔雀石绿的微生物及功能基因资源进行挖掘，并对其降解途径及代谢产物进行研究，为近海环境修复提供潜在的、可应用的生物资源 ...

Integrative Conservation, Volume 5, Issue 1, Page 74-85, March 2026.This study investigates distribution patterns of Galliforms in the Indian Himalayas, focusing on factors influencing their occurrence, regions of high diversity and endemism, and their overlap with protected areas. Our study highlights the need for assemblage‐level conservation strategies in high Himalaya which primarily relies on snow leopard‐focused ...

野生动物学报, 2015 近年来,城市化对鸟类的影响受到生态学家的广泛关注。于2014年3～5月对哈尔滨市区7块城市绿地中鸟类的分布和数量进行了调查,同时选取4个城市化指标以确定影响哈尔滨市区鸟类群落的主要城市化因子,并进一步分析哈尔滨城市化与鸟类群落的关系。调查共记录到鸟类121种隶属于14目38科。在7个样地中,鸟类群落多样性指数显示为:H群力湿地公园>H植物园>H太阳岛>H东北林业大学林场>H兆麟公园>H四季上东小区>H儿童公园; 均匀性指数E群力湿地公园>E植物园>E东北林业大学林场>E太阳岛>E四季上东小区>E兆麟公园>

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
