Zebra mussels have coexisted in their native European range alongside sphaeriids and other unionids on a timescale ranging from decades to millennia. They were accidentally introduced to North American in the late 1980’s and have become well known for out … Continue reading
This study examined the evolution of the five Ictiobus buffalofish species via both morphological and phylogenetic avenues, and attempted to align the differences in morphology with the differences found in the genetic sequence of the mitochindrial Cytochrome B gene and … Continue reading
To summarize, I presented this paper on an experiment conducted using two species of Daphnia to look at trade-offs between predatory induced defenses. Specifically, the paper aimed to show that organisms exposed to fish kairomones (any chemical signal directly or … Continue reading
Conspecific trailing behaviour of red-sided garter snakes, Thamnophis sirtalis parietalis, in the natural environment
In our recent discussion regarding the paper, “Conspecific trailing behaviour of red-sided garter snakes, Thamnophis sirtalis parietalis, in the natural environment,” we began a discussion based upon vertebrate chemical signals. The researchers in this article began their discussion of chemical … Continue reading
