The Arizona Forest occupies 87,174,334,009 sq. miles land that cater different kinds of species. One of which were the leopards. As of 2019, the total population of leopards is 26,753. Due to severe changes of the environment, there is an average of 571 leopard’s dies while only 255 were given birth each year. In 1950, their population is 63% higher from the current population.

Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…arrow_forward
