BIO 227 Lecture Notes - Lecture 8: Habitat Destruction, Bycatch, Overexploitation
Document Summary
External factors that cause species to become endangered. Resource for humans: or compete with humans for a shared resource. Bycatch: exhuman conversion from prairie to agriculture (ex. old cemetery) Small, highly localized populations are very vulnerable: close to the brink of extinction, vulnerable to many stochastic (random) factors: Inbreeding depression in florida panthers: kinked tail, deformed sperm, cryptochoicism. Rare species are more vulnerable to extinction due to factors such as environmental change. Species in general are vulnerable to extinction due to:
