To better understand the respiratory physiology of triploid fish, we conducted an analysis of O2 and CO2 transport in diploid and triploid chinook salmon (Oncorhynchus tshawytscha) swimming at 0.4 body lengths (BL)·s–1, at 2.0 BL·s–1, and at the critical swimming velocity (Ucrit). While O2 consumption rates (MO2), MO2 max, and Ucrit did not differ between ploidies, triploids had a smaller incre...

There has, as yet, been little study of nutrient disturbance and its consequences on the functional biology of primary consumers in coral reefs. The processing of epilithic algal communities by the damselfish Stegastes nigricans was investigated at La Réunion, at two sites of a fringing reef, oligotrophic for one and eutrophic for the other. Differences between sites were analyzed in quantifyin...

Freshwater conservation efforts require an understanding of how natural and anthropogenic factors shape the present-day biogeography of native and non-native species. This knowledge need is especially acute for imperiled native fishes in the highly modified Lower Colorado River Basin (LCRB), USA. In the present study we employed both a taxonomic and functional approach to explore how natural an...
