Relationships between species feeding traits and environmental conditions in fish communities: a three-matrix approach

Understanding the relationships between species biological traits and the environment is crucial to predicting the effect of habitat perturbations on fish communities. It is also an essential step in the assessment of the functional diversity. Using …

Testing the species traits-environment relationships: the fourth-corner problem revisited

Functional ecology aims at determining the relationships between species traits and environmental variables in order to better understand biological processes in ecosystems. From a methodological point of view, this biological objective calls for a …

Resource partitioning in a grazer guild feeding on a multilayer diatom mat

The gut contents of a guild of invertebrate grazers inhabiting the moss Fontinalis and feeding on epiphytic diatoms in a small Que´bec stream were analyzed to characterize resource partitioning and food selection. A multivariate approach (RLQ …
