Mark Hay
Professor and Teasley
Chair of Environmental Biology
Georgia
Institute of Technology
Expertise:
Reef Ecology, Trophic Interactions, Community Ecology, Chemical Ecology
Issues of Interest:
1. Effects of overfishing and nutrient addition on the structure and function
of temperate and tropical reefs
2. How organisms use chemistry to solve base life problems (predation, competition,
pathogens)
3. Consumer-prey interactions
Current Projects:
1. See #1 above.
2. Chemical ecology of plant-herbivore interaction in lakes and rivers
3. Predator defense of marine worms [temperate vs. tropical, hard vs. soft-substrate,
and shallow vs. deep sea]
4. Ecological impact of a non-native crab in coastal GA
5. Coral/ seaweed/ herbivore/ nutrient interactions
6. Biocomplexity consequences of phytoplankton chemical defenses
7. Seaweed chemical ecology
Location:
Coral reefs; Temperate reefs (Grays Reef); Temperate and Tropical soft substrate
communities (mud flats, sand flats, seagrass beds); Rivers and Lakes.
