Survival mechanisms of the central mudminnow (Umbra limi), fathead minnow (Pimephales promelas) and brook stickleback (Culea inconsrans) for low oxygen in winter.
Notes: species abbreviations are as follows: RED, northern redbelly dace (Phoxinus eos); FINE, finescale dace (Phoxinus neogaeus); FAT, fathead minnow (Pimephales promelas); BRASS, brassy minnow (Hybognathus hankinsoni); PEARL, pearl dace (Semotilus margarita); GOLD, golden shiner Notemigonus crysoleucas); BLACK, blacknose shiner (Notropis heterolepis); BROOK, brook stickleback (Culaea inconstans); MUD, central mudminnow (Umbra limi); BURBOT, burbot (Lota lota); WHITE, white sucker (Catastomus commersoni); SMALL, smallmouth bass (Micropterus dolomieue); CRAP, black crappie (Pomoxis nigromaculatus); PERCH, yellow perch (Perca flavescens); IOWA, Iowa darter (Etheostoma exile); JOHN, Johnny darter (Etheostoma nirum).
Selective predation upon pelvic phenotypes of brook stickleback
, Culaea inconstans, by northern pike, Esox lucius.
Four fish were collected, including three Creek Chubs (Semotilus atromaculatus) and a Brook Stickleback (55 mm standard length, HSU 3186).
However, the Brook Stickleback has been found in Nebraska since at least the early part of the last century.
Brook stickleback (Culaea inconstans [Kirtland]), a new addition to the upper Colorado River Basin fish fauna.
Several other species, including the brook stickleback, pumpkinseed sunfish, creek chub, and yellow perch exhibited relatively low abundances in 1983-1987 but increased abundances in 1988-1992 [ILLUSTRATION FOR FIGURE 3 OMITTED].
In contrast, the brook stickleback, pumpkinseed sunfish, creek chub, and yellow perch all exhibited increased abundances between 1988 and 1992.
brook stickleback, but most species still exhibited few age classes.
Age 0 brassy minnow and blackchin shiner were present in only 1 of 10 yr and redbelly dace, brook stickleback, and yellow perch in 3 of 10 yr.
In this study we continue to build the brook stickleback database by systematically examining the courtship repertoires from four geographically disjunct populations belonging to the Mississippi lineage (Sutherland Creek, Nebraska) and the Atlantic lineage (Tooley Creek, Southern Ontario; Algonquin Park, Central Ontario and Two Mile Creek, New York).
Adult brook stickleback were collected using minnow traps in early May of 2004 and 2006 from Sutherland Creek, Nebraska (41[degrees]08'13"N, 101[degrees]07'28"W); in 2004 from Two Mile Creek, New York (42[degrees]05'52"N, 78[degrees]26'38"W); in 1993 from Ring-Neck Pond, Algonquin Park, Ontario (45[degrees]34'52"N, 78[degrees]23'19"W) and in 1992 and 2006 from Tooley Creek, Ontario (43[degrees]52'11"N, 78[degrees]46'53"W).
This latter point is particularly important because brook stickleback females spend approximately 9.
A study by Maret and Peters (1980) indicated that the plains topminnow was most commonly associated with brook stickleback in Nebraska, and Propst (1982) found the plains topminnow with brook stickleback in the South Platte River drainage.
When mean CPUE for all six native species were compared at all sites only two species, creek chub and brook stickleback had higher abundances at sites absent of plains topminnow.
