Humic substances influence sodium metabolism in the freshwater crustacean Daphnia magna.
Humic substances are ubiquitous components of natural waters with important roles in alleviating metal toxicity to aquatic organisms. Recent literature reports suggest that humic substances may also exert direct influences on biota. This study investigated the influence of two commercially available humic substances on sodium metabolism in Daphnia magna, a hyperregulating freshwater crustacean....
متن کاملQuaternary diversification in a sexual Holarctic zooplankter, Daphnia galeata.
The effects of Quaternary glacial range partitioning on the diversification of Holarctic biota remain unclear. Glacial refugial lineages may form vicariant species, hybrid products, or merge after secondary contact. Here, we assess the effects of Quaternary glaciation on a Holarctic sexual zooplankter, Daphnia galeata, with apparently marked dispersal capacity and a widespread hybrid lineage in...
متن کاملResveratrol and food effects on lifespan and reproduction in the model crustacean Daphnia.
Longevity is a highly variable life history trait and its variation is attributable to both genetic and environmental factors. Exploring well-known environmental factors in a new model system is a useful approach to explore taxonomic variation in plasticity of longevity. We examined responsiveness of the Daphnia pulex clone TCO to potentially related interventions that have been reported to ext...
متن کاملAncient androdioecy in the freshwater crustacean Eulimnadia.
Among the variety of reproductive mechanisms exhibited by living systems, one permutation--androdioecy (mixtures of males and hermaphrodites)--is distinguished by its rarity. Models of mating system evolution predict that androdioecy should be a brief stage between hermaphroditism and dioecy (separate males and females), or vice versa. Herein we report evidence of widespread and ancient androdi...
متن کاملThe Daphnia Genomics Consortium Meeting: the genome biology of the model crustacean Daphnia.
The fourth Daphnia Genomics Consortium Meeting was held from July 7th through July 9th, 2007 at Indiana University (Bloomington, IN, USA). This year’s meeting was entitled The Genome Biology of the Model Crustacean Daphnia and was highlighted by the initial public release of the draft version of the Daphnia pulex genome. In collaboration with the US Department of Energy Joint Genome Institute (...
