Document Summary
Slide 7: doll sheep and humans have type 1 curve, this means survival doesn"t drop off until later in age. Exponential growth model: the little r helps with that curve, dn/dt =rn is the exponential growth model. If r is negative, the population will have an exponential decrease. If r is positive, the population will have an increase at en exponential rate: assumes unlimited growth model. Intraspecific competition function (accounts for competition within the species: as population size gets smaller/closer to 0 then the model predicts exponential growth, but whe the population approaches k, then growth stops (because its approaching the carrying capacity) If we move them and take some dogs away and move them if it is density independent, then the population will stay pretty small. If it is density dependent (less resources available) then the population will grow back towards that carrying capacity: assuming that population size is.
