Habitat, environment and niche: What are we modelling?
Article Abstract:
The interrelated working definitions of habitat, environment and niche are suggested, whereby the concept of habitat remains associated with descriptive/correlative analyses of the environments of organisms, while the niche concept is reserved for mechanistic analyses. A mechanistic understanding of the niche is critical, while predicting an organism's distribution under novel circumstances such as a species introduction or climate change.

Delayed timing as a strategy to avoid nest-site competition: testing a model using data from starlings and flickers
Article Abstract:
It is examined whether natural selection can favor a strategy of delayed nesting in flickers to reduce overlap in breeding phenology with starling competitors. A mathematical model based on reproductive parameters is also reviewed.
