Ecology theory is the study of interactions among plant, animal, microbial and abiotic factors within an ecosystem.Elements of this field include genetics, speciation, population dynamics, plant communities and predator/prey dynamics. The processes that relate to genetics include mutation, genetic drift and population bottlenecks. Within the interactions flora and fauna associations there are many types of mathematical models to explain the spatial relations and population dynamics of individual taxa. Besides models that depict the growth and decline, there are more specialized analyses which portray seed dispersal, migration patterns, symbioses and pollination. The abiotic factors of meteorology, soil and water chemistry are also vital in understanding the total ecological community.
The phenomena of autotrophism, herbivory and carnivory are intrinsic to ecology theory, in order to understand the complexity of the food web.Processes disease transmission and organism decay are further inherentelements;further, within the realm of ecology theory are the phenomena of habitat fragmentation, refugia and biological corridors;these larger scale features address the integrity of entire ecological communities and lead to strategies of conservation biology.
