Qualitative spot biotic survey of Oaks Creek, White Creek, Cripple Creek, and Moe Pond in Otsego County, New York

As non-native species move across the landscape and hydrofracking and other human impacts increase in scope, it is becoming more critical than ever that we can quantify changes to community structure. In order to do that, however, we must first have baseline data on which species are initially present. These baseline data also have the benefit of facilitating speciesspecific research by identif...

Spatial and Temporal Variation in Fish Assemblage Structure in Village Creek, Hardin County, Texas

-Fish assemblages were sampled seasonally at Village Creek, a blackwater tributary of the Neches River in Hardin County, Texas. Forty-four fish species were captured from aquatic mesohabitats that included backwater pools, deep channel pools, sloping sandbanks, sandy riffles, and shallow channel margins. Associations between fish assemblage structure and mesohabitats were strong, yet also affec...

Hays County, Texas

The widespread Berberis trifoliolata is sympatric with the narrowly restricted B. swaseyi in central Texas, where apparent intermediates occur. A detailed field study of sympatric populations in northern Hays Co. during 2004 to 2007 clarifies the morphological and phenological differences between the two species and shows that intermediates almost surely arose from hybridization. Limited eviden...
