Increased dorsal spine number in threespine stickleback has been associated with avian predation (Reimchen, 1980; Reimchen and Nosil, 2002), whereas a decreased number of spines has been associated with Odonate naiad predation in both threespine stickleback (Reimchen and Nosil, 2002) and brook stickleback (Culaea inconstant Reist, 1980).

Cluster analyses based on fish abundance at sites classified according to succession al environment indicated that four species (northern redbelly dace, Phoxinus eos; brook stickleback, Culaea inconstans; finescale dace, P.
Four species (redbelly dace, brook stickleback, fat-head minnow, and finescale dace) were predominant in all successional environments, so that variation in species composition among environments was due to the addition of less abundant species (Table 2).

(Culaea inconstans), brassy minnow (Hybognathus hankinsoni), northern redbelly dace (Phoxinus eos), finescale dace (Phoxinus neogaeus), fathead minnow, creek chub (Semotilus atromaculatus), blackchin shiner (Notropis heterodon), and pump-kinseed sunfish.
The brook stickleback
Culaea inconstans is an intriguing species with which to begin building such a database because the specific designation "inconstans" means "changeable" in Latin; the term was initially chosen by Kirtland (1840) to reflect morphological variability in the frequency of dorsal spines (Nelson, 1969; reviewed in Mattern, 2006b).

(Culea inconstans), central stoneroller (Campostoma anomalum), creek chub and plains killifish for the third axis; and fathead minnow, longnose dace and white sucker for the fourth axis (Table 2).
