Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have d...

Glaciers along the western Antarctic Peninsula are retreating at unprecedented rates, opening up sublittoral rocky substrate for colonization by marine organisms such as macroalgae. When macroalgae are physically detached due to storms or e...
Changes in the relationship between zooplankton and phytoplankton biomasses across a eutrophication gradient [0.03%]

Understanding how gelatinous zooplankton communities are structured by local hydrography and physical forcing has important implications for fisheries and higher trophic predators. Although a large body of research has described how fronts,...
Microbial generation of elemental mercury from dissolved methylmercury in seawater [0.03%]
海水溶解甲基汞的微生物生成元素汞作用

Elemental mercury (Hg0) formation from other mercury species in seawater results from photoreduction and microbial activity, leading to possible evasion from seawater to overlying air. Microbial conversion of monomethylmercury (MeHg) to Hg0...
Intertidal clams exhibit population synchrony across spatial and temporal scales [0.03%]
潮间带.clam.种群同步性具有时空尺度效应

Long-term datasets can be particularly useful for parsing out factors influencing populations, yet few studies have utilized continuous datasets to quantify population dynamics in bivalve molluscs. We used dynamic factor analysis on a clam ...
Insights into the loss factors of phytoplankton blooms: The role of cell mortality in the decline of two inshore Alexandrium blooms [0.03%]
关于引发赤潮的水华藻类损失因子的见解——两种近海亚历山大藻种群衰退期间细胞死亡率的作用

While considerable effort has been devoted to understanding the factors regulating the development of phytoplankton blooms, the mechanisms leading to bloom decline and termination have received less attention. Grazing and sedimentation have...
Feeding strategies for the acquisition of high-quality food sources in stream macroinvertebrates: Collecting, integrating, and mixed feeding [0.03%]
关于溪流大型底栖无脊椎动物获取高质量食物资源的摄食对策：采集、整合和混合对策

Fen Guo et al.
Aquatic macroinvertebrates play an important functional role in energy transfer in food webs, linking basal food sources to upper trophic levels that include fish, birds, and humans. However, the trophic coupling of nutritional quality betw...
Seasonal plasticity in photoprotection modulates UV-induced hsp gene expression in copepods from a clear lake [0.03%]
透明湖泊无节幼虫类甲壳动物季节性光保护塑性调节紫外线诱导的热休克蛋白基因表达

B Tartarotti et al.
Zooplankton from clear alpine lakes is exposed to stressful levels of solar UV radiation (UVR). As these pelagic organisms experience high UVR and large changes in solar radiation conditions between ice-free and ice-cover periods, they have...
A synoptic survey of microbial respiration, organic matter decomposition, and carbon efflux in U.S. streams and rivers [0.03%]
美国河流和溪流中的微生物呼吸作用、有机质分解以及碳释放的综合调查研究
