Document Summary
Lecture 19 community ecology: competition: think about multiple populations of individuals, 2 populations of individuals of different species. Other statistics you can calculate from life tables. Reproductive values in humans: reproductive value is lower in birth. Individuals are going to die before they become reproductive: max reproductive value at teen years, reproductive value lowers as you age. What determines where species live: dispersal, abiotic climates, climate, nutrients, species interactions, competition, predation, mutualism. Species interactions: competitions = negative for species a and b, predation = positive for species a and negative for species b, benefits predator and harms prey, host-parasite, plant-herbivore, mutualism = positive for species a and b. Interested in two main things: how interactions change population dynamics, how it determines population and community structure, how it affects evolutionary dynamics, how it affects adaptation, and how it affects co-evolution. Intra- competition for resources that happen among same species.
