We conduct research on several ecological interactions and evolutionary patterns that are broadly grouped in two categories:
Ecology of host-parasite interactions is poorly understood in marine and estuarine ecosystems, yet there disease can have major impacts on host populations in a diverse array of coastal species. We have opportunities to study several host-parasite systems:
o Rhizocephalan cirripedes (especially Loxothylaccus panopaei) that are parasitic castrators of xanthid crab (Rhithropanopeus harrisii, Eurypanopeus depressus, Panopeus spp.).
Bacterial infections of fish, especially Aeromonas sp. in esturarine carp (Cyprinus carpio).
Trematodes in grass shrimp (Palaemonetes pugio), marsh snails (Melampus spp., Littorina spp.), and shorebirds/raccoons.
Bopyrid isopods (Probopyrus pandalicola) in branchial chambers of grass shrimp (Palaemonetes pugio).
"Dermo" (Perkinsus spp.) in oysters and infaunal bivalves (e.g., Macoma spp.)
Parasitic copepods (Mytilicola spp.) in bivalves (e.g., Macoma spp.)
We are interested in the ecology and evolution of complex life histories of marine and estuarine invertebrates and fish, with emphasis on:
- Larval biology of marine invertebrates, especially brachyuran crabs.
- Comparative demographic variables (reproductive output and fecundity, growth, size, age at maturity, longevity) of brachyuran crabs and barnacles.
- Impacts of fishing on demographic variables.
- Demography of invasive species.
