In population dynamics, depensation or the Allee effect (Allee et al. 1949) corresponds to the reduction in birth rate when a population is small due to the difficulty of finding mates and the harmful effects of inbreeding. A simple model to account for this that generalizes the logistic model (1.7) is Ṅ=-r N(1-(N)/(E))(1-(N)/(K)) . where 00. | Numerade

72.3.4 (The Allee effect) For certain species of organisms, the effective growth rate N is highest at intermediate N. This is called the Allee effect (Edelstein-Keshet 1988). For example, imagine that it is too hard to find mates when N is very small, and there is too much competition for food and other resources when N is large. Show that N/N = r - a(N - b) provides an example of the Allee effect; if r, a, and b satisfy certain constraints, to be determined. b) Find all the fixed points of the
