Answer #1

Nt = N0 X \lambdat

N0 - Initial population - 135

\lambda - Extnction coefficient - 0.75

t - time in years = ?

Nt = 135 X 0.754 = 135 X 0.316 = 42.71

When t = 4 the population size is 42.7 which is less than 50 hence it will take 4 years for the population to become less than 50

    A species of horned toads has a (starting) population size of 5000 individuals. Every month, 400 individuals are born. However, you cannot assess the number of individuals that die every month because after death the animals are susceptible to a fungus that quickly degrades their carcasses. You can measure, though, that the population is declining over time, with the population size decreasing by 250 individuals every month (i.e., deltaN/deltaT). Calculate the total number of deaths per month and the per...
