Assessing the spatial and temporal patterns of total mercury δ 15N and δ13C in yellow perch and their prey items from a contaminated site, St. Lawrence River, Cornwall, ON
As a result of the legacy of industrial contamination over the last century, areas of sediment deposition in the St. Lawrence River at Cornwall, ON, contain high concentrations of mercury (Hg). The popular sport-fish ...
The effect of copper on kairomone-mediated responses by wild Daphnia pulicaria clones from along a copper gradient
Kairomones are infochemicals that benefit a heterospecific receiver. Chaoborus spp. release a kairomone from their gut when feeding on Daphnia spp. Daphnia respond to kairomone by shifting life history parameters or ...
Microsatellite variability in four contemporary rhinoceros species : implications for conservation
Rhinoceroses are arguably the most endangered of all large mammal taxa. In order for ongoing conservation of this species to be successful, it is crucial to accurately characterize the remaining genetic diversity for all ...
The effects of habitat connectivity and regional heterogeneity on artificial pond metacommunities
While much evidence suggests that ecosystem functioning is closely related to biodiversity, present rates of biodiversity loss are high. With the emergence of the metacommunity concept ecologists have become increasingly ...
Molecular Identification and Messenger RNA Levels of a Monocarboxylate Transporter (MCT) in Fundulus Heteroclitus, a Hypoxia Tolerant Teleost Fish
Monocarboxylate transporters (MCTs) are bi-directional symporters that couple proton movement to a variety of glycolytic metabolites, including lactate and pyruvate. As such, MCTs not only play a crucial role in pH ...
Why is a robin’s egg blue? Exploring the evolution of egg colour in birds
A recent hypothesis for explaining blue-green eggs in birds suggests that they may be a sexually selected signal of female (and thus nestling) quality that males use to make parental investment decisions. Although this ...
