Trait-Based Approaches in the Analysis of Stream Fish Communities
Overall, studies of fish-habitat relationships that apply habitat templates and hierarchical filters dominate this sample; the most frequently used traits are related to feeding.
Genetically-Improved Tilapia Strains in Africa: Potential Benefits and Negative Impacts
Two genetically improved tilapia strains (GIFT and Akosombo) have been created with Oreochromis niloticus (Nile tilapia), which is native to Africa. In particular, GIFT has been shown to be…

Riparian forest and length-slope (LS) factor were the most important watershed-scale variables and mostly positively correlated with IBI scores, whereas substrate and riffle-pool quality were the important reach- scale variables in the ECBP.
REGIONAL FRAMEWORKS APPLIED TO HYDROLOGY: CAN LANDSCAPE-BASED FRAMEWORKS CAPTURE THE HYDROLOGIC VARIABILITY?
Regional frameworks have been used extensively in recent years to aid in broad-scale management. Widely used landscape-based regional frameworks, such as hydrologic landscape regions (HLRs) and…
Associations among hydrologic classifications and fish traits to support environmental flow standards
Classification systems are valuable to ecological management in that they organize information into consolidated units thereby providing efficient means to achieve conservation objectives. Of the…
Determination of optimal riparian forest buffer dimensions for stream biotalandscape association models using multimetric and multivariate responses
This work applied partial correlation and multivariate linear regression on functional fish community response attributes and the index of biotic integrity using stream samples from the Eastern Corn Belt Plain Ecoregion of Indiana, USA to find the optimal buffer dimension.

A quantitative classification scheme is constructed for North American freshwater fishes to better describe rarity in fishes and provide researchers and managers with a tool to streamline conservation efforts, and could be applied to other taxa to aid conservation decisions.
Land-use Impacts on Watershed Health and Integrity in Indiana Warmwater Streams
Abstract Many warmwater streams in the midwestern United States have been negatively influenced by human land-use practices. From Jun. through Aug. 2002 and 2003, tributaries (n = 50) of the upper…
Comparative Utility of Selected Frameworks for Regionalizing Fish-Based Bioassessments across the United States
Abstract Regional frameworks for bioassessment are necessary to stratify natural geographic variation in biotic assemblages and to calibrate bioassessment metrics and indices. In the United States,…
Predicting invasiveness of species in trade: climate match, trophic guild and fecundity influence establishment and impact of non‐native freshwater fishes
Trait-based models for the establishment and impact stages of freshwater fish invasion are developed and used to screen non-native species common in international trade, and suggest the water garden trade poses the greatest risk of introducing new invasive species, followed by the live food and aquarium trades.
