Individual-based models (IBMs) are increasingly used to link the dynamics of individuals to higher levels of biological organization. Still, many IBMs are data hungry, species specific, and time-consuming to develop and analyze. Many of these issues would be resolved by using general theories of individual dynamics as the basis for IBMs. While such theories have frequently been examined at the ...

The pulchella-group of Alona s.l. (Cladocera: Anomopoda: Chydoridae) is transferred to Ovalona Van Damme et Dumont, 2008, and an emended diagnosis is provided. Ovalona meridionalis (Sinev, 2006) is removed from Ovalona due to differences in thoracic limb morphology. At the moment, Ovalona consists of 17 species, and is the largest natural genus of Aloninae. A key for the world fauna and diagnos...

Batrachochytrium dendrobatidis is responsible for amphibian declines worldwide. Decreasing the aquatic density of this chytrid through consumption its infectious zoospores by Cladocera (water fleas) may mitigate impact chytridiomycosis. Understanding predator-prey relationship requires insights in zoospore ingestion rate an average water flea, but such data are almost non-existent. We investiga...

The ecosystem of the Caspian Sea have been strikingly changed by human activities. This area has undergone significant ecological alterations and serious environmental degradation since the beginning of 1990s. The impact of fish cage culture on the zooplankton community was studied in the southwestern Caspian Sea, off Jafrud during January to April 2013. A total of 12 zooplankton belonging to 9...

The studies conducted in spring have shown the main trends changes structure of zooplankton kultuk zone Volga River delta years that differ hydrological and temperature regimes. It was revealed low-water (2012, 2014), with a decrease volume runoff, water level, reduction duration floods, characterized by relatively low species richness, high biomass Copepoda Cladocera. At same time, highest rat...

A total of 22 species, 16 Rotifera, 4 Cladocera and 2 Copepoda, were identified in the study carried out pool located Iskenderun Technical University campus. The most species found Lecanidae family with 5 species. Pleuroxus wittsteini detected this is a new record for inland waters Turkey.

A new species of Chydoridae cladoceran (Crustacea: Cladocera: Chydoridae) is described from the Cerrado (a Brazilian tropical savanna ecoregion), Central Brazil. Ephemeroporus quasimodo sp. nov. differs from other species of the genus in a high dorsal keel on carapace and posterior part of the head shield, which resembles a hunchback. Parthenogenetic females, ephippial females and males are des...
