| Summary: | (based on faunal composition at sample sites and including all seasons) were run on two data sets of ten and twenty two also canonically correlated with seven physical parameters backwater habitats vs. riffle and sandbank habitats. The backwaters vs. the stream channel, sandbank and riffle blackwater tributary of the Neches River in Hardin County, by depth. Size structures and relative abundances were by dissolved oxygen levels, while the second gradient was Creek from diverse aquatic mesohabitats, (e.g., backwater distinct, but were strongly affected by discharge examined for the dominant fish sub-populations within fish assemblage structure and mesohabitats were generally Fish assemblages were sampled seasonally at Village Creek, a fluctuations. from each site. The first canonical correlation gradient was habitats. The ten species with highest site occurrence were identified a strong depth gradient that contrasted pool and mesohabitats and for rarer species that occurred in more than one mesohabitat. Seven species displayed year-round spawning or had extended spawning seasons (e.g., Cyprinella venusta, Pimephales vigilax, Notropis sabinae). Associations between pools, deep channel pools, sloping sandbanks, sandy riffles, primarily a dissolved oxygen gradient secondarily influenced primarily a water temperature gradient secondarily influenced second PC axis identified a dissolved oxygen gradient between shallow marginal regions). Principal component (PC) analyses species with highest site occurrence. The first PC axis Texas. Forty four fish species were captured at Village |
