RATE OF ENVIRONMENTAL CHANGE AND ADAPTATION IN THE COPEPOD EURYTEMORA AFFINIS

Genetic and Physiological Adaptation of the Copepod EURYTEMORA AFFINIS to Seasonal Temperatures.

Evidence of significant additive genetic (genic) variance in temperature tolerance of the copepod Eurytemora affinis was derived from several sources. Differences were observed between average tolerances of progeny of animals exposed and not exposed to heat shock in a power plant. Genic variance was estimated using offspring-parent regressions, full-sib, and half-sib covariances, with quite con...

Noncanonical GA and GG 5′ Intron Donor Splice Sites Are Common in the Copepod Eurytemora affinis

The noncanonical 5' intron donor splice sites GA and GG are exceedingly rare in described eukaryotic genomes; however, they are present in ∼12% of introns in the genome of the copepod Eurytemora affinis Failure to recognize the high frequency of these donor sites compromised the modeling of genes in this newly sequenced genome, including 10 conserved ionotropic glutamate receptor (GluR) family ...

Hydrocarbon Contamination and the Swimming Behavior of the Estuarine Copepod Eurytemora affinis

Life-history responses to changing temperature and salinity of the Baltic Sea copepod Eurytemora affinis

To understand the effects of predicted warming and changing salinity of marine ecosystems, it is important to have a good knowledge of species vulnerability and their capacity to adapt to environmental changes. In spring and autumn of 2014, we conducted common garden experiments to investigate how different populations of the copepod Eurytemora affinis from the Baltic Sea respond to varying tem...

Trade-Offs between Predation Risk and Growth Benefits in the Copepod Eurytemora affinis with Contrasting Pigmentation

Intraspecific variation in body pigmentation is an ecologically and evolutionary important trait; however, the pigmentation related trade-offs in marine zooplankton are poorly understood. We tested the effects of intrapopulation phenotypic variation in the pigmentation of the copepod Eurytemora affinis on predation risk, foraging, growth, metabolic activity and antioxidant capacity. Using pigme...
