The Effect of Food Concentration on the Juvenile Somatic Growth Rate of Body Length, Fecundity and the Production of Resting Eggs by Moina brachiata (Crustacea: Cladocera) Single Females [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2012
The study addresses the effect of different food concentrations of green alga Chlorella vulgaris on the life cycle parameters (the body length, specific juvenile somatic growth rate of body length, the number of offspring in the first clutch of ...

Copepods vs. cladocerans in the field.

, 2013
Mean (±SE) proportion of copepods (white) and cladocerans (gray) observed in over ten years of field data from Lake Krankesjön and Lake Ringsjön during springs colder and warmer than the overall mean temperature in May (11.48°C) of all years investigated.

Cladocerans versus copepods: the cause of contrasting top-down controls on freshwater and marine phytoplankton.

, 2006
Top–down control of phytoplankton by crustacean mesozooplankton is a cornerstone of freshwater ecology. Apparently, trophic cascades are more frequently reported from freshwater than from marine plankton.

Exposure to toxic Microcystis via intact cell ingestion and cell crude extract differently affects small-bodied cladocerans

, 2022
Cyanobacterial blooms are increasingly common in aquatic environments worldwide. These microorganisms cause concern due to their ability to produce cyanotoxins.

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Winter decrease of zooplankton abundance and biomass in subalpine oligotrophic Lake Atnsjøen (SE Norway)

Journal of Limnology, 2019
Despite the rapidly changing winter conditions in temperate ecosystems, little attention has been devoted to the effects of these changes on lake ecology.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

Restoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Paleoenvironments of the Last Interglacial–Glacial Transition on the East European Plain: Insights into Climate-Driven Ecosystem Dynamics

Quaternary
A multiproxy study of a new Pleistocene locality at Ivantzevo, Moscow Region, was conducted to reconstruct paleoenvironments from the Middle Pleistocene to the Last Pleniglacial.

Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

Restoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...
