Lotka-Volterra. equations. Competition. Adding in resources. Species interactions:. Competition (- , -). Predation (+ , -). (. Herbivory. 41:. Ch. 42:. Ch. 44:. Ecology. Ecology. : study of interactions between organisms and their environments – science of relationships, studied by ecologists. Abiotic . Factors:. non-living parts of an organism’s environment. Geography. Resources. Phylogeny. Community. Redrawn from Fauth . et al. . (1996). Community. – collection of species that occur at the same place & time, circumscribed by natural (. e.g. ., serpentine soil), arbitrary, or artificial (. Course Objectives. Define the following ecological terms: Population, population density, community, population distribution, diversity, Limiting factors, resources, biotic potential (. r ), . carrying capacity . abiotic. conditions.

What is a population and how do ecologists study it. Explain . the difference between a niche and . habitat. Explain the predator/prey . relationship and carrying . capacity on the graph. . Explain why animals fight.
