What factors did the researchers determine prevented the Soa

What factors did the researchers determine prevented the Soay sheep introduced to Hirta Island form growing exponentially?

Solution

Following are the factors that researchers determined prevented exponential growth of Soay sheep in Hirta island:

a. Climate change. When high population density combines with poor winter weather.

b. Low resistance to nematode parasites makes them less successful reproductively.

c. Lacks ideal conditions for growth and survival offspring.

d. The effects of increasing density reduces the birth rate.

e. Scarcity of food aspopulation increases.

f. Harsh weather mainly cold wet winters weaken the sheep and reduce food availability thereby decreasing population.
