A researcher studies two populations of small mammals, one living in a coastal forest and the other in an inland grassland. The animals are morphologically very similar, with only slight differences in fur colour. They produce distinct mating calls and do not interbreed in the wild. However, when individuals are brought together in captivity, they mate and produce fertile offspring.
With reference to the biological, morphological and ecological species concepts, compare how each concept would classify these two populations. Give reasons for your answer.
