Short Take!2015


Natural habitat in the eastern United States has diminished over the past century as a result of introduction of invasive species. The loss of particular native species can potentially influence the structure of animal communities through changes in habitat structure and abiotic conditions. Eastern hemlock (Tsuga canadensis) is declining in abundance from the effects of the invasive sap-sucking hemlock woolly adelgid (Adelges tsugae).  The loss of intact hemlock forests may impact the composition of small mammal communities. My dissertation project is timely and relevant because eastern hemlock populations are declining and the ecological effects are likely to ramify throughout the forest community. It is important to know how small mammals are affected before the eastern hemlock is lost. This research will quantify small mammal biodiversity, abundance, and community structure in four treatments of a large-scale forest manipulation in response to hemlock woolly adelgid deforestation and pre-emptive logging management regimes, both of which will become more common as the adelgid invasion continues to spread through northern New England.
