Taxonomic Comments
This species exhibits significant clinal variation in dorsal and pelvic spine lengths and in body depth, as well as complex behavioral differences among populations (see Sublette et al. 1990). See Gach (1996) for information on geographic variation in mtDNA and biogeography. See McLennan (1993) for a phylogenetic analysis of the Gasterosteidae based on behavioral characters.

Range Extent Comments
The range includes most of the southern half of Canada (Atlantic and Arctic drainages from Nova Scotia to Northwest Territories) and the northern part of the eastern United States, extending south in the Great Lakes-Mississippi River basins to Colorado (Woodling 1985), Nebraska, Illinois, Ohio, Pennsylvania. A population in the Canadian River system in northeastern New Mexico was regarded as probably introduced (through bait bucket or incidental to stocking of exotic salmonids) by Sublette et al. (1990) and Gach (1996), though the apparent native status in eastern Colorado (Woodling 1985) suggests that the New Mexico population could be native. Brook sticklebacks have been introduced in various places south of the native range, such as in Alabama, Kentucky, Tennessee, northwestern Colorado, northeastern Utah (Modde and Haines 1996, Great Basin Nat. 56:281), and California. Present distribution was influenced by postglacial dispersal from separate refugia in the Mississippi and Ohio river basins (Gach 1996).
Occurrences Comments
This species is represented by a large number of occurrences (subpopulations) (e.g., see map in Lee et al. 1980).
Threat Impact Comments
No major threats are known.
Ecology & Habitat

Habitat

This species generally occupies cool, clear, heavily weeded, spring-fed creeks, small rivers, lakes, and ponds, usually in shallow, quiet to flowing pools and backwaters over sand or mud (Lee et al. 1980, Page and Burr 2011). Sometimes it burrows into soft bottoms. Occasionally this fish can be found in brackish water. In a lake in Manitoba, adults were most abundant at the outer margin of emergent vegetation (Moodie 1986). Eggs are deposited in a nest made of plant material by the male just above the bottom in shallow water.

Ecology

Population size varied greatly among years in a Manitoba lake; summer kill and winter kill common; recolonization via intermittent runoff streams (Moodie 1986).

Reproduction

Spawns spring and summer (about mid-May to mid-July in Manitoba, Moodie 1986). Females may spawn every few days when food is abundant. Eggs hatch in 7-11 days. Male tends eggs and fry. Sexually mature by age I, age II and III also are included in the breeding population (Becker 1983, Lee et al. 1980, Moodie 1986).
