Habitat utilization and breeding success in Leach's Storm-Petrel: the importance of sociality
Models like "ideal-free distribution" that have been developed to predict the spatial distribution of animal populations typically assume that high densities will occur in preferred habitats. We investigated habitat utilization in Leach's Storm-Petrels (Oceanodroma leucorhoa) at the c...

Models like "ideal-free distribution" that have been developed to predict the spatial distribution of animal populations typically assume that high densities will occur in preferred habitats.

A strong positive relationship between occupancy and both hatching and breeding success suggests that sociality plays an important role in habitat utilization and reproduction in Leach's Storm-Petrel. |
