Commensalism, +, - interaction, one species takes advantage of another for no benefit. Limiting factors- presence, absence or magnitude of biotic or abiotic env. factors that can limit population growth. We can look at limiting action if we look at breeding. Why do species breed in certain areas could be biotic, could be abiotic habits areas change, disease cured, or it may be that there is not enough food or water in certain. One aspect of a limiting factor is the threshold effect. Threshold increases the chances of rapid env. What we deal with as conservationists are populations of species surrounded by environments living together in communities within ecosystems. Any and all of these interactions and processes have been and will continue to be affected by. Anthropogenic impacts, and it is the goal of conservation to minimize these impacts and assure the sustainability of the world"s biodiversity and ecosystem services for future generations.
