atromaculatus, one Lepomis cyanellus, and one Noturus
eleutherus (mountain madtom) is a locally common species found in two Level III ecoregions in Tennessee: Interior Plateau and Ridge Valley.
3], and Miranda and Kidwell (2010) induced injury (mortality, spinal injury, and tissue hemorrhage) to four nongame species (creek chub, Semotilus atromaculatus; bluntnose minnow, Pimephales notatus; tadpole madtom, Noturus
gyrinus; and redfin darter, Etheostoma whipplei) at higher power densities between 1.
A revision of the catfish genus Noturus
Rafinesque, with an analysis of higher groups in the Ictaluridae.
Chromosomal evolution in North American catfishes (Siluriformes, Ictaluriidae) with particular emphasis on the madtons, Noturus
First record of the ictalurid catfish, Noturus
phaeus, from Arkansas.
Three species (black bullhead, Ameiurus melas, tadpole madtom, Noturus
gyrinus, and sea catfish, Arius felis) were represented by single individuals.
We captured 14 species of fish over the course of the study: bluehead chub (Cyprinidae: Nocomis leptocephalus), creek chub (Cyprinidae: Semotilus atromaculatus), rosyside dace (Cyprinidae: Clinostomus funduloides), redbreast sunfish (Centrarchidae: Lepomis auritus), yellow bullhead (Ictaluridae: Ameiurus natalis), American eel (Anguillidae: Anguilla rostrata), swallowtail shiner (Cyprinidae: Notropis procne), white shiner (Cyprinidae: Notropis albeolus), margined madtom (Ictaluridae: Noturus
insignis), green sunfish (Centrarchidae: Lepomis cyanellus), bluegill sunfish (Centrarchidae: Lepomis macrochirus), mosquitofish (Poeciliidae: Gambusia affinis), warmouth sunfish (Centrarchidae: Lepomis gulosus), and a darter (Percidae: Percina spp.
Although in vertebrates it constitutes a particularly stable feature because it does not seem to be subject to direct selective pressures, chromosome variability has been shown in some species through the detection of polymorphisms in the chromosome diploid number, like in Noturus
albater Taylor 1969 (LeGrande 1981), Gymnotus campo L.
Fathead minnows Pimephales promelas and stonecats Noturus
Jlavus represented 3% and 1% of the catch, respectively, and were captured in low abundances throughout the study area (Table 1).
Eight species show a decrease with Ameiurus melas, Noturus
gyrinus, Erimyzon sucetta, and Moxostoma duquesnei greater than 50%.
