Ecological and evolutionary effects of dispersal on freshwater zooplankton
… expansion, and gene flow among populations. Freshwater zooplankton are aquatic crustaceans that typically develop resting stages as part of their life cycle. Their dormant propagules allow organisms to disperse both temporally and among habitats. Additionally, because a number of species are …

Genotypic Differences and Life-History Trade-Offs in the Freshwater Zooplankton, Daphnia Pulicaria, Under Natural Levels of Food Limitation
… differences can be compared. The parthenogenetic freshwater zooplankton, Daphnia pulicaria, is a model organism to investigate and disentangle the genotypic from the phenotypic influences of life history variation. While Daphnia spp. life history has been extensively studied, few have examined the …

Effects of diversity on community assembly dynamics in newly formed pond communities
… diversity (both intra- and interspecies) of freshwater zooplankton in newly constructed pools was manipulated in a 2x2 fully factorial design. Zooplankton communities and several abiotic variables were sampled every two weeks (from May to August) for 3 years. Estimates of overland dispersal …

Understanding and predicting the response of reservoir zooplankton communities and water quality to climate change
Freshwater zooplankton communities are highly sensitive to environmental change and are critical indicators of water quality. Zooplankton are central organisms in freshwater food webs, composed of diverse taxa playing different functional roles in freshwater food webs as food sources for upper …

Behavioral Response to UVB Differs in Subalpine Populations of Daphnia Melanica
<em>Daphnia </em>are a genus of freshwater zooplankton that inhabit ponds and lakes. They are commonly used as a model organism because they can reproduce clonally and are considered a foundation species in pond ecosystems. <em>Daphnia melanica</em> that inhabit the subalpine ponds of the Olympic …

Hazard assessment of a mixture of pharmaceuticals detected in the upper Tennessee River of Daphnia magna and the determination of riverine zooplankton assemblage as it relates to chitobiase activity
… secondary production, chitobiase activity and zooplankton density and biomass samples were measured in six Tennessee River tributaries.

Intraspecific variation in resource use, dormancy investment, and competitive ability in the facultative parthenogen Daphnia pulicaria
… I use the facultatively parthenogenetic zooplankton Daphnia pulicaria to address several questions related to the breadth and consequences of intraspecific variation. Freshwater zooplankton species are important subjects for ecologists. In particular, crustaceans in the genus Daphnia have …
