Document Summary
Introduction: what is ecology, forest birds testing competition theory. Ecologists who want to see why species live together, focus a lot on competition & predation. Ultimately you will have one species that will be happy and one that is starving: warblers in spruce forest. Different species of warblers feed on different places of the tree. So they can coexist as no one is monopolizing everything. Division of resources take place as postulated if species are using the same resources then they are using the resources in different ways (in terms of space) The remaining species is released from competition. It"s habitat expands and abundance can grow: where black throated green warblers are absent, yellow rumped warblers move their feeding zone upward. If competitor is not present, then you would use all of the resource: nutrient budgets and large scale ecology. Bio 2f03: many things happen in branches.
