Intraspecific Variation of Three Phenotypic Morphs of Daphnia pulicaria in the presence of a Strong Environmental Gradient
Freshwater lake ecosystems often exhibit strong oxygen, and temperature gradients across which many zooplankton species live. Daphnia sp. vary in their ability to up-regulate hemoglobin in response to low oxygen environments. ...
Food Quality Effects On Life History Trait Correlations In Daphnia
Life history theory assumes that correlations among fitness-related life history traits should be negative among individuals, reflecting resource allocation constraints among traits such as growth and reproduction. These ...
