月湖底泥疏浚后底栖动物群落的恢复及其与环境的关系 [PDF]
, 2012 研究对月湖底泥疏浚后底栖动物群落动态进行逐月的周年调查,并分析了底栖动物密度、生物多样性与环境因子的关系,结果表明:疏浚导致大型底栖动物基本消失,现存量从疏浚前的(4387±885)ind·m-2降低至(80±21)ind·m-2。疏浚后,寡毛类成为受干扰系统恢复过程中的先锋种类,在春季(4月)和秋冬之际(11月)出现2个密度高峰,分别为(1010±230)ind·m-2和(1538±408)ind·m-2,而摇蚊幼虫在疏浚一年后的秋冬季密度达到高峰(2021±612)ind·m-2 ...

Climate Impacts on Lake Food‐Webs Are Mediated by Biological Invasions
Global Change Biology, Volume 31, Issue 3, March 2025.Climate change and invasive species are major threats to biodiversity, but their combined effects are often overlooked. By analyzing fish communities in French lakes, we found that climate warming negatively impacts size and trophic diversities. However, these effects are largely mediated by the warming‐induced increase in exotic species richness ...

Cross‐boundary connections of biodiversity and ecosystem functioning in boreal ecosystems
Ecological Monographs, Volume 95, Issue 1, February 2025.Abstract Relationships between biodiversity and ecosystem functioning (BEF) are typically investigated separately in different ecosystem types, often neglecting connections across ecosystem boundaries. Here, we examined the cross‐boundary relationships between terrestrial and aquatic biodiversity and terrestrial and aquatic ecosystem function (here ...
