The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. For example, even though bald eagles (Haliaeetus leucocephalus) and African fish eagles (Haliaeetus vocifer) are both birds and eagles, each belongs to a separate species group. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. In plant and animal breeding, procedures have been developed which deliberately utilize the effects of dispersion (such as line breeding, pure-line breeding, backcrossing). Historically, human population control has been implemented with the goal of limiting the rate of population growth. This is an example of ________ isolation. two populations of organisms belong to the same biological species when they.
