Environmental Variability
The environment varies in many ways that are relevant to the ecology of species, populations, and individuals. For example, the occurrence and abundance of a predator in the environment is an important source of variability in survival conditions. The environment often refers to conditions extrinsic to an organism that affects its rates of reproduction, survival, and movement.
One way to organize this variation is along 3 dimensions: one that describes variability in time, one that describes variability that occurs across space, and one that describes how temporal variability differs across space (or equivalently how variability across space differs over time). These three are sometimes called
I've studied pure temporal variation, pure spatial variation, and spatio-temporal variation. They are each linked and give rise to unique, and biologically relevant, phenomena.
