The answer for this question is "founding population arrives, biogeographic isolation occurs, genetic changes occur, reproductive isolation results" so it is letter A
ANSWER: POPULATION ECOLOGY
EXPLANATION:
The scientific field that deals with populations (i.e all individuals of a single species inhabiting a community) and how they interact with their extrinsic environment, is referred to as POPULATION ECOLOGY.
Thus, it's categorized under population ecology, because the research depicts how the number of individuals (beetles) in a population changes in time and the gross impact on their number decrease and loss of all the individuals (extinction) over a period of time.
They are unique in the sense that sawfish are able to reproduce in the wild without the need of a partner. They were able to engage in asexual reproduction. In parthenogenesis, an egg cell is created by dividing a singular precursor cell into four separate ones. The cell that develops into an egg cell retains the cytoplasm and other vital cellular structures. The remaining three contain excess genetic material.
Fertilization happens when one of the three extra cells essentially turns into a sperm cell and combines with the egg cell.
