Microhabitat Conditions Influence Mesohabitat Associations And Distribution Of Larval Salamanders In Headwater Streams, J. M. Yeiser, Stephen C. Richter
Biological Sciences Faculty and Staff Research
Distribution patterns of stream biota are the result of complex interactions between individuals and their surrounding environment. Determining the spatial scale by which an organism is most influenced is paramount to understanding distribution patterns. Using a multi-scale approach, we investigated factors influencing habitat associations of larval Ambystoma barbouri (streamside salamander) and Eurycea cirrigera (southern two-lined salamander) in three Kentucky headwater streams. We used likelihood ratio G tests to identify associations between species and mesohabitat (i.e., runs, riffles, and pools), and we used microhabitat variables to predict the presence and abundance of salamanders via a priori multiple regression modeling. Ambystoma barbouri …

The spatial and temporal variation in fish distribution, assemblage structure, and habitat associations were investigated in relation to the available macrohabitats (riffle, run, or pool) in Gilbert's Big Creek and Elisha Creek, 2nd and 3rd order streams, respectively, located within the Red Bird River watershed in southeastern Kentucky. A total of 7,662 individuals were captured; 3,038 from Gilbert's Big Creek (21 species) and 4,624 from Elisha Creek (19 species). The most prevalent species overall in both streams was the creek chub (Semotilus atromaculatus). Most fish species were distributed in the middle sampling sites in the spring, the lower sites in …
