Abstract

The endangered vermilion darter (Etheostoma chermocki) is endemic to the Black Warrior River system, Mobile Basin, Alabama. Collections of specimens obtained from

Evolution of the premaxillary fraenum and substratum in snubnose darters and allies (Percidae: Etheostoma)

“…Another explanation for the results is that food resources are sufficiently abundant in all substrata, such that selection to specialize on particular substrata is relatively weak. The diets of snubnose darters and allies consist primarily of chironomid larvae (Page & Mayden, 1981;Carney & Burr, 1989;van Snik Gray et al, 1997;Khudamrongsawat et al, 2005;Alford & Beckett, 2007;Khudamrongsawat & Kuhajda, 2007;Barton & Powers, 2010;Sterling et al, 2013). Chironomids frequently comprise the majority of benthic macroinvertebrate communities and can be found in a variety of lotic habitats, including sandy pools and rocky riffles and runs (Inoue et al, 2005;Syrovátka et al, 2009).…”
