Document Summary
A group of individuals of a single species inhabiting a particular area. Ex: the population of moose on isle royale in lake superior. Important to determine because individuals are not homogeneously distributed across the landscape (cid:1) Population boundaries can be determined by the differences in demography. Connectivity- the link between two or more populations by dispersal of individuals (cid:1) (cid:1) (cid:1) Ecological population- a group of individuals of a species that occupy a defined area. The boundaries are determined by an ecologically relevant change in the environment (cid:1) Evolutionary population- a local group of individuals that mate at random (a deme) The boundaries are determined by the barriers to mating and gene flow. Genet- a genetically distinct individual in a plant population. Ramet- a physiologically distinct individual in a plant population. Unitary organisms- exist as separate and distinct individuals. Modular organisms- develops repetitive patterns of growth in body.
