Question

The northern red-legged frog, or Rana aurora, is found along the western coast from British Columbia to Northern California. Their typical breeding season lasts from January to March. The foothill yellow-legged frog, or Rana boylii, is found along the western coast from northern Oregon to central California. Their typical breeding season lasts from April to July. What mechanism might keep Rana aurora and Rana boylii from mating?

A) anatomical isolation
B) temporal isolation
C) geographic isolation
D) behavioral isolation

Im pretty sure its C or D...

Answer 1

there are 3 parts to the question

Step-by-step explanation:

The red-legged frog breeds in ephemeral ponds from January through March. Its relative, the bullfrog, breeds in permanent ponds from late March through May. temporal isolation

In Death Valley, California, there are several ponds that are formed in various areas of the desert. Each pond contains its own species of fish unique to the pond it lives in. geographic isolation

A male firefly attempts to impress a female firefly for mating. The female does not recognize the pattern of light used by the male firefly and mating does not occur. behavioral isolation

Answer 2

The answer is B) temporal isolation.

Temporal isolation is a type of reproductive isolation, which could be prezygotic or postzygotic. Temporal isolation is prezygotic reproductive isolation since it occurs before fertilization and zygote production. Temporal isolation is result of temporal differences in breeding. In this example, the breeding season of Rana aurora lasts from January to March while the breeding season of Rana boylii lasts from April to July. So, these two breeding seasons do not coincide and these species could not mate.
