Seasonal variation in phytoplankton biomass imposes strong selection pressures on planktonic herbivores such as Daphnia, with both low and high food availability shaping life-history strategies. While the threshold food level (TFL) has been...
The role of alternative microbial resources in competition between Daphnia species [0.03%]
斑翅叶肢介属物种间竞争中替代微生物资源的作用机制研究

We studied competitive interactions between Daphnia longispina and D. magna competing for a single algal resource of varying quality in treatments with low and enhanced amounts of bacteria. We proposed that the outcome of competition is inf...

In a laboratory experiment conducted in thermally stratified glass tubes, so-called "plankton organs", we tested two alternative hypotheses concerning the role of maternal effects on Daphnia vertical migration behavior induced by the presen...
The effect of environmental variation on stable coexistence of competitors: experimental evidence from zooplankton (Daphnia magna and D. pulex) [0.03%]
环境变异对竞争者稳定共存的影响：大型溞和管状溞的实验证据

Sigurd Einum et al.
Coexistence of competing species may be influenced by environmental variation. Specifically, theory suggests that short-term environmental variability can contribute to long-term coexistence among competitors. Here, we address the role of e...
Effects of fish stocking and removal on plankton communities and trophic status in deep alpine-type lakes of the Five Lakes Valley (Tatra Mountains): Bottom-up and top-down regulation in the ecology of offshore animals. The lifetime passion of Z.Maciej Gliwicz [0.03%]
鱼类放养与清除对五湖谷高山型深湖浮游生物群落和营养状态的影响：Z.Maciej Gliwicz的终生热情——近岸动物生态学中的底控与顶控调节

Mirosław Ślusarczyk et al.
Most alpine-type lakes in the Tatra Mountains were stocked with salmonid fish during the 19th and 20th centuries, triggering profound ecological shifts. In the Five Lakes Valley, trout introductions into Przedni Staw Polski, Czarny Staw Pol...
Seasonal variability of the microzooplankton biomass and community composition on the Northeast US Shelf [0.03%]

Grazing on phytoplankton by microzooplankton is a critical process in making energy available to higher trophic levels, shaping marine food webs, and biogeochemical cycling. Despite its key role, the drivers of grazing remain poorly constra...

Algal biovolume is a standard measurement for limnological and oceanographic studies, which is used to proxy biomass and productivity. Manual and automatic methods can be applied to estimate biovolume from phytoplankton images. We examined ...
Response of the mesozooplankton community in the western Gulf of Maine to changing oceanographic conditions: the 2010 regime shift [0.03%]
2010年海洋环境变化对缅因湾西部仔稚鱼群落的影响：以海洋生态制作为基础

The Gulf of Maine has experienced pronounced changes in recent decades, including rapid warming and changes in circulation. Notably, a shift in water masses entering the Gulf occurred around 2010. Concurrent declines in critically endangere...
Effect of salinity on the feeding behavior of Cordylophora caspia (Pallas, 1771) (Hydrozoa) [0.03%]

Cordylophora caspia, is considered an invasive species in America. We isolated this hydrozoan from the brackish water section of the River Tuxpan (State of Veracruz, Mexico) and cultured it in the laboratory on mixed prey of copepods and ro...
Sedimentary evidence of invasive cladoceran Bosmina (Eubosmina) coregoni presence on the Pacific coast of North America over four decades before first detection [0.03%]
北美太平洋沿岸四十年来入侵溞类舟形袖水蚤的沉积记录早于首次发现

While the invasion of Eurasian cladoceran Bosmina (Eubosmina) coregoni to the Laurentian Great Lakes is well-documented, its spread to the west coast of North America is less understood. We provide evidence that Bosmina (Eubosmina) coregoni...
