Natural enemies have inconsistent impacts on the coexistence of competing species
Journal of Animal Ecology, Volume 90, Issue 10, Page 2277-2288, October 2021., 2021 Using a large competition experiment and a modern coexistence theory framework, the authors tested the impact of a generalist parasitoid wasp on competition between Drosophila hosts. They found the generalist natural enemy could alter the fitness differences between Drosophila species, but that the impact on pairwise coexistence was mixed. Abstract The

Journal of Ecology, Volume 107, Issue 6, Page 2697-2712, November 2019., 2019 We integrated multiple components of plant and herbivore diversity to unravel the linkages that drive biodiversity relationships and determine the consequences of biodiversity loss across trophic levels. Our study suggests that lepidopteran phylogenetic diversity is significantly affected by plant species loss when basic splits in the evolutionary ...

Shuitu Baochi Xuebao, 2021 为了研究消落带不同土地利用类型和水淹强度下土壤活性有机碳组分特征及其主要的影响因子，选取不同海拔高程（水淹强度）与不同土地利用类型的消落带土壤为研究对象，定量解析土地利用方式与水淹强度对三峡水库消落带土壤活性有机碳组分的影响，并分析土壤活性有机碳与土壤理化性质之间的关系。结果表明，消落带土壤活性有机碳含量总体上随着水淹强度的增强而减小。土地利用、水淹强度及其交互作用对土壤活性有机碳影响的解释度分别为22.1%，13.7%，9.3%；土壤微生物生物量碳主要受土地利用、土地利用与淹水强度交互作用的影响 ...

Bank collapse-landslide failure mechanism of typical reverse rock bank slope in Three Gorges Reservoir area [PDF]
At present, most of the reverse rock slope toppling instability failure is interpreted as a progressive overall instability failure controlled by dip angle and structural plane. However, the phenomenon of leading edge collapse is common in some reservoir
