Document Summary
Chapter 52: an introduction to ecology and the biosphere. Introduction: discovery ecology: 2008 in papua new guinea, found tiny frog inflating vocal sac to call for mate, frog only 8mm long, among smallest adult vertebrates on earth. Predators and pathogens affect size of population: only found in papua new guinea. Concerned with how an organism"s structure, physiology, and behavior meet the challenges posed by its environment: population ecology: population is a group of individuals of the same species living in an area. Analyze factors that affect population size and how and why it changes through time: community ecology: community is group of populations of different species in an area. Examines how interactions between species, like predation and competition, affect community structure and organization: ecosystem ecology: ecosystem is community of organisms in an area and the physical factors with which those organisms interact.
