Roman Zajac, Ph.D.
Zajac Current Research Programs:
I am an ecologist with varied research interests. These include mapping and characterizing sea floor communities and understanding how sea floor structure affects the ecological dynamics and biodiversity of these environments, applying landscape approaches to ecological dynamics in salt marshes and the sea floor, how climate change may be affecting salt marsh habitats and biota, feeding behaviors of fish on coral patch reefs, and macroalgal successional dynamics on patch reefs. I am also working on applying low level high resolution imagery collected by unmanned aerial vehicles (UAVs or drones) to collect spatial data for both the salt marsh and intertidal mudflat research being conducted in my lab.
- Application of landscape ecology approaches to sea floor ecology
- Effects of saltmarsh change on coastal ecology
- Assessing the impacts of fish social foraging on coral reef communities
- Responses of sea floor communities to natural and human disturbances
- Application of geographic information systems (GIS) in environmental assessment
