Document Summary
Bio 208 lecture 19 wednesday, february 28, 2018. Interference competition: exploitative competition, lotka-volterra model of competition, competition coefficient, state space graphs, and the isocline of zero population growth, competitive exclusion principle, character displacement. Isoclines: represents zero growth for both species, species abundances will want to lie on the isoclines, they don"t want to increase or decrease, but stay stable. If the point is above both species" isoclines, species one will decrease along the x axis, and species two will decrease along the y axis: combined vector would be a decrease in both species. If the point is below both species" isoclines, species one will increase along the x axis, and species two will increase along the y axis: combined vector would be a decrease in both species. If evolutionary pressure is strong enough, they will just alter the resources they use.
