Frederic GovedichWorldI work on freshwater leeches (Euhirudinea)
Donna KashianWorldEcotoxicology invasive species
Christopher LaumerWorldI am interested in the taxonomy and phylogeny of the free-living flatworms, especially the so-called "microturbellarian" groups. My particular focus is in the ubiquitous family Prorhynchidae, but I can be easily lured by other taxa as well. A secondary focal group are the freshwater Nemertea, commonly exemplified by the genus Prostoma.
Steve OrmerodWorldGeneral stream and river ecology, mostly Europe and Asia
Heather ProctorWorldAcari: Hydracarina (Hydrachnellae/'water mites'); Oribatida, Astigmata, Mesostigmata
H. Maurice ValettWorldEcosystem ecology of riverine landscapes (aquifers, rivers, streams, and floodplains)

Charles SwartUSA (Southeast)I have visited several museums across the U.S. and studied the available semi-aquatic hemiptera collections. I am particularly interested in the Belostomatidae.

J. HansonCanada (East)I am not a taxonomist rather I am a community ecologist who prefers to correctly identify the fishes, crustaceans (mainly decopods), and molluscs (mainly bivalves)that show up in predator stomachs.
