There’s something fishy about one of Connecticut’s minnows, and the topic hooked researchers in the Department of Biology.
During the last ice age, Connecticut was covered by layers of snow and ice, forcing organisms to seek refuge elsewhere. After the glaciers retreated, recolonization of the fauna and flora resulted in the diversity of native species that inhabit the state today.
“But where did they come from? How did they come back to the Northeast to give us all the organisms we see today?” asks biology graduate student Michelle Tipton. “These questions are of particular interest to the ichthyologists at Wesleyan with regards to fishes.”
In an upcoming issue of Ecology and Evolution, a scientific open access journal, faculty and students provide some of the first genetic evidence of what took place during the most recent post-glacial recolonization events, which provided Connecticut and the northeast with its native fish populations. To begin filling the void of information for this large biogeographic question, they started their research with this ubiquitous minnow.
