Document Summary
Things back to the lotka volterra model of inter-specific competition: mutualism goes back to exponential growth, with adding another species that"s a mutualist, population growth will increase continuously, need a factor that limits this infinite growth. Population dynamics of mutualism: limits of population growth, third species such as predator or competitior, strong intra-specific competition, diminishing returns to mutualism as thepopulation grows. If we place a species where there are only few species present, it will have rapid growth and less limiting factors (invasive: 2 species arrive and they"re mutualists, they will grow in populations. Invasive seed dispersing ant does the same thing: outcomes between native vs. invasive dispersing species placed little mesh nets all over the place and placed different types of ants and plants. Invasive plant is dispersed by invasive species: with native ant, mostly native plants germinated in mesh nets, with invasive ant, mostly invasive plants germinated in mesh nets.
