Taxonomic Comments
"Populations in the northeast have lower genetic diversity than those to the south and west and show no isolation by distance" (Baer 1998).

The only other member of the genus occurs in Middle America (Lee et al. 1980).

Ecology & Habitat

Habitat

Habitat includes heavily vegetated, standing and slow-flowing waters; weedy pond and stream margins, marshes; from fresh to brackish (about 30 ppt) water (Lee et al. 1980, Page and Burr 2011).

Ecology

Populatio age structure may be significantly impacted through predation by GAMBUSIA HOLBROOKI on small HETERANDRIA (Schaefer et al., Copeia 1994:516-520).

Reproduction

See Scrimshaw (1944, Copeia:180-183) for information on reproduction.
