56: Conservation BiologyConservation biology is about conserving biodiversity, not just saving rare species. Species are going extinct at a relatively high rate today. 3 levels of biodiversity conservation: 1. conserving variation or genetic diversity*conserving all genes within a species2. protecting different species within a community3. preserving a range of environments Biodiversity Hotspots: to be a hotspot, it must have Fairly large number of different species, lost of endemic species (species that only occur in one area and nowhere else), and areas that are under a fair amount of threat. Humans have increased rate at which species move around the world by bringing them into new areas or traveling with them.Inbreeding and genetic drift can be a serious problem to conserving genetic diversity. *if there is only one type of individual, they could only mate with themselves, causing a loss of alleles and loss of variation in the population. Need to mix genes up to restore diversity and variation (which can be done by introducing a new species for the individuals to mate with) *Also sometimes it is necessary to remove non-native species out of an environment because the native species were being
