BIO205H5 Lecture Notes - Lecture 15: Metapopulation, Natural Experiment, Guppy
Document Summary
Understand numbers and formulas but do not have to calculate big numbers. Predator and prey populations display dynamic interactions. Predators and prey influence each other"s evolution. Population: individuals of the same species living in a particular area at the same time. Areas that have satiable habitats others do not. Subpopulations: smaller groups of conspecifics that live in isolated habitat patches; population is broken up into subpopulations. One population can be divided into smaller populations. Metapopulation: a population that is broken up into subpopulations between which there is infrequent dispersal. Individuals are going back and forth between subpopulations. It is a specific structure of a population. We have no interactions between two groups you just have two separate populations. Learn the basic structure of these types of population. Ecologists have studied wolves and moose on isle royale for 57 years. Perfect study for this as it is a isolated system. Little chance for these two species two cross islands.
