BIO205H5 Chapter Notes - Chapter 9: Philopatry, Metapopulation, Quadrate Bone
Document Summary
Population: a group of individuals of the same species that habitat in a given area at a time. Density: # of individuals per unit area. Age structure: proportion of individuals in various age classes. Dispersion: spacing of individuals relative to each other. Dynamics: change in # over time as a result of death, birth, and movement. Unitary organisms- organisms that grows from birth to adult as single integrated unit, often with determinate development. Most organisms that are unitary are determinate. Fish is indeterminate and grows throughout their life span. Modular organisms- organism that exhibit indeterminate growth involving repeated units, such as plants blanches or shoots. Series of repeated units are added to the region of active growth, meristem. Genet genetically distinct, free living organism that arise from a fertilized egg. Modular population consists of sexually produced genet and asexually produced ramet. Distribution of population describes its spatial location and the area in which all its members live.
