Document Summary

Population: a group of individuals of the same species that occur together in space and time. N(t+1) = n(t) + b - d + i - e. Often negative - r declines as population density increases. Sometimes positive - r declines with population density. Random variation in reproduction and survival of individuals in a population. Random variations in environmental conditions that a ect birth and death (births and deaths) Environmental stochasticity rates of individuals in a population. Large environmental perturbations lead to dramatic population declines. Catch as many of species as you can and mark them in a particular way and let them go and then see how many have been marked when you return later and estimate population size from this. A set of methods for evaluating the threats faced by the population, their risks of decline,
