Download Edge Effects, Ecological Traps - Introduction to Conservation Biology - Lecture Slides and more Slides Biology in PDF only on Docsity! Edge Effects & Ecological Traps • Build upon population growth models, source- sink dynamics • Contrast edge population dynamics at the edge and core • Evaluate how selection for edge and core habitat affects population persistence Docsity.com Edge Effects & Traps • Not all habitat is created equal • E.g. Bobolinks nest in grasslands and in hayfields • When harvested early, breeding success is lowered dramatically • Densities as high or more • Ecological trap Docsity.com Edge Effects & Traps • Habitat edges have long been hypothesized as “ecological traps” for songbirds Docsity.com Edge Effects & Traps • In this exercise, you will model an organism that that breeds in edge and core habitats, where each habitat type has its own, unique reproductive and survival parameters • All individuals in core habitat will have one specific rate while those in edge will have another specific rate Docsity.com
