Name: Potts, Daniel (Researcher)

Institution: SUNY Buffalo State

Description of Expertise:

I investigate how plants interact with, and influence, their environment from the scale of leaves to ecosystems. I am driven by questions related to anthropogenic global change such as nonnative plant invasions, nitrogen deposition and changes in precipitation associated with global warming. To address these questions, I combine traditional methods in community and physiological ecology with approaches adopted from soil science, hydrology, and micrometeorology.

Description of Expertise:

I study the ecology of the hemlock woolly adelgid, its interaction with other invasive and native hemlock pests, and exactly why it is so harmful to the eastern hemlock. I also study adelgid-resistant eastern hemlocks, which have been discovered in NJ and CT.

Name: Richardson, David (Researcher)

Institution: SUNY New Paltz

Description of Expertise:

Within the last several years, didymo has invaded a number of locations in the Northeast United States. I am interested in determining where didymo exists and understanding if there are biogeochemical explanations for the recent invasion. I would like to quantify the extent of the blooms (biomass accrual) and to understand the impact of the blooms on the physical template of the streams (seston quality and transport), the biogeochemical implications of the blooms (nutrient cycling) and the effects on the higher trophic communities of macroinvertebrates and fish.

Name: Robinson, Michael (Manager)

Institution: NYSDEC / WRI

Description of invasive species management work:

I serve as the Aquatic Invasive Species Coordinator for NYSDEC Region 7. In collaboration with multiple partners and stakeholders, we conduct surveys for early detection and rapid response of invasive species, manage, monitor, and control known infestations of high priority, and engage the public in education and outreach, as well as organize and participate in community invasive species control events. In short, our mission is to “conserve, improve and protect New York’s natural resources and environment…” Our recent efforts have focused largely on hydrilla management, a particularly aggressive invasive, as well as water chestnut, a well established but troublesome invader.
