dc.description.abstractWhile the importance of invertebrates in the diets of waterfowl has been established for several decades, few studies have shown a direct quantitative relationship between invertebrate communities and avian performance. In this study, we investigate the relationship between the abundance and mass of macro invertebrates and the survival and maturation of juvenile American coots (Fulica americana) on the prairie potholes of Manitoba. Invertebrate samples were collected from thirteen potholes and analyzed with survival and maturity data from a concurrent study investigating egg-size and egg-composition dynamics of juvenile American coots. Using simple regression analyses, no relationships were found between macro invertebrate abundance or biomass and coot performance. To further analyze the data, we performed a principle component analyses on the original invertebrate data sets and used the factor scores in multiple regression analyses. These results corroborated our initial finding of no clear relationship between invertebrate abundances and biomass and juvenile coot performance. Here we propose two alternative explanations for the lack of relationship. First, predation, and not starvation, may be the main source of mortality for juvenile coots. Secondly, due to uncertainty about the exact diet of juvenile coots, our analysis may be concentrating on or neglecting the specific invertebrates that limit coot performanceen_US
