Answer #1

It is true because there are many factors which affects the survival of small population like environmental, demographic effect.

Demographic effect - includes reproductive and mortality rates due to influence of stochastic variations. These rates could result to the fluctuations in size and may result in the extinction of small population.

Environmental effect or factor- there are two types of year: - bad year ( low birth rate and high death rate) and good year ( high birth rate and low death rate) . The bad year affects more badly to small population and this can bearable by large population.

A rare cactus from Arizona (Echinocactus horizonthalonius) has only five known populations. One of these populations was monitored over five years in the early 1990s with 2, 3, 25, 32, and 86 plants recorded. The effective population size (Ne) is 5.48 while the average population census size (Nc) is 29.6. a. Give a biological explanation for the difference between these two estimates. b. Why is effective population size an important measurement for natural populations? Use the example above to support...

The equilibrium theory of island biogeography states that larger islands will have a lower  rate than small islands because larger islands can support larger populations. Islands that are closer to the mainland will have a higher  rate than ones further away because individuals are more likely to successfully travel to close islands, and a lower extinction rate because the ____________ effect will be higher, preventing declining island populations from going extinct through the arrival of new immigrants.
