What are the five species of denroica warblers?
Cape may
myrtle
black throated green
black bumian
bay-breasted
What is the aim of the warbler paper?
looking at how closely related bird species coexist in the same habitat without directly outcompeting each other
How do warblers coexist?
by partitioning resources spatially and behavioraly
each species forages in different parts of the same trees, reducing interspecific competition
What did MacArthur propose?
Natural selection favoured divergence in foraging strategies to allow stable coexistence
What is the vascular plants paper about?
How SAR for vascular plants in North America varies along a latitudinal gradient
- How z-value changed with latitude
What were the results of the vascular plant paper?
Higher z-values found at lower latitudes - in tropical regions species richness increases more rapidly with area
What do the results of SAR paper indicate?
greater habitat heterogeneity or niche specialisation in lower latitudes
