The structure and spatial heterogeneity of zooplankton in small lake river Wel (Poland)

Limnological Review, 2014
The aim of the study was to determine changes in potamoplankton structure caused by lakes in the fluvial system of the small River Wel. The river flows through 10 lakes. The study was conducted in 2007 and 2008.

Unveiling Zooplankton Diversity Patterns: The Differential Influence of Macrophyte Belts on Species and Functional Metrics

Diversity
Species and functional diversity are essential frameworks for analyzing changes in planktonic communities. In lakes and rivers, macrophytes within the coastal zone are a primary determinant of zooplankton community structure and function.

Permafrost thaw lakes and ponds as habitats for abundant rotifer populations

Arctic Science, 2018
Thermokarst lakes and ponds were sampled across a range of permafrost landscapes in subarctic Québec (Nunavik, Canada) to compare their rotifer and other zooplankton characteristics with a set of rock-basin lakes and ponds in the region.

Effects of climate on size structure and functioning of aquatic food webs [PDF]

, 2010
In aquatic food webs, the role of body size is notoriously strong. It is also well known that temperature has an effect on body size. For instance, Bergmann’s rule states that body size increases from warm to cold climates.

Diversity of Rotifera in Freshwaters of Bolivia: An Updated Checklist

Diversity
Biodiversity records are of great importance, especially in light of the biodiversity crisis. Here, we present a study on the diversity of rotifers in Bolivia based on an extensive investigation of the literature published so far.

Zooplankton - fish interaction in the littoral zone of Nyanza Gulf, Lake Victoria [PDF]

, 1999
The zooplankton community of the littoral zone of Nyanza Gulf, Lake Victoria, was studied between June 1998 and June 1999 to identify and quantify various zooplankton groups, and investigate the interactions that occur between them and the littoral fish ...

Maternal age effects on offspring lifespan and reproduction vary within a species

Ecology and Evolution
Across diverse taxa, offspring from older mothers have decreased lifespan and fitness. Little is known about the extent to which maternal age effects vary among genotypes for a given species, however, except for studies of a few arthropod species.

Short communication: Culture of Chlorella ellipsoidea in different inexpensive medium and used as food for production of rotifer, Brachionus calyciflorus [PDF]

, 2016
Rotifers are multicellular animals with body cavities that are partially lined by mesoderm. These organisms are valuable live food for larval fish and crustacean culture. Several characteristics of rotifers, including their nutritional quality, body size
