Journal ArticleDOI

Power of stable isotope techniques to detect size-based feeding in marine fishes

TL;DR: Analysis here suggests that size-based feed- ing studies should aim to sample over 40% Lmax range of the population, as the sample size required to maintain sufficient statistical power diminishes almost exponentially with increasing body size range.
Journal ArticleDOI

The Reef-fish Fauna of the Northern Patagonian Gulfs, Argentina, South-western Atlantic

TL;DR: The reef-fish assemblages of the San Jose and Nuevo gulfs are a mix of warm-temperate fauna from the South-western Atlantic Province, and cold-temmediate species from theSouth-American Province; however, warm- temperate fishes dominated in both gulfs.
Journal ArticleDOI

Methodological uncertainty in resource mixing models for generalist fishes.

TL;DR: Using field data from omnivorous reef fishes, this study illustrates how uncertainty may be taken into account in non-Bayesian models and provides guidance on the interpretation of existing published mixing model results and in robust analysis of new resource mixing scenarios.
