Document Summary
Oral microbiome: the genomes of the microbes that live inside our bodies, there are millions. Symbiosis: interaction between two different organisms living in close physical association. Biodiversity: the variety of life in an environment / ecosystem. Ecology emcompasses both the biotic (living) components and the abiotic (physical and and chemical) components of the environment. It includes the study of energy and nutrient movement through ecosystems -- the networks of interacting organisms in an area, plus the physical environment. Populations are groups of interacting conspecifics (e. g. inter-mating); We can characterize individual populations in terms of their . Direct sampling: going out and counting individuals directly. Mark and recapture: mark a certain amount and then come back later and sample how many are marked / unmarked (proportions) Counting methods: indirect counting, take into account patterns of dispersion. Indirect sampling: measuring amount of scat to see how many individuals in a given area.
