Document Summary
Mutualism: both species benefit from interaction (+/+) Commensalism: one species benefits, other is unaffected (+/0) Co-evolution: the influence of closely associated species on each other in their evolution. When in adapting to their environment, two or more organisms evolve together. Intraspecific interactions: members of same species compete for limited resources. Leads to reduction in fitness for both individuals. Interspecific interactions (including competition): members of different species compete for a shared resource. Niche: an organisms niches is a range of conditions (biotic & abiotic) & resources in which it could survive & reproduce. Niche overlap: when two species compete for the same limiting resources. Competitive exclusion: states that two species that compete for exact same resources cannot stably coexist if other ecological factors remain constant. Competitive exclusion principle: also referred to as gauze"s law of competitive exclusion. Asymmetric competition: unequal division of resources amounts competing plants.
