Male Dendropsophus microcephalus calling. Sexual selection in amphibians involves sexual selection processes in amphibians, including frogs, salamanders and newts.Prolonged breeders, the majority of frog species, have breeding seasons at regular intervals where male-male competition occurs with males arriving at the waters edge first in large number and producing a wide range of vocalizations ...
Farmers also divert water from streams for irrigation, which may affect the frog's breeding sites. Because scientists saw the frogs next to roads, they think it may tolerate disturbed habitats. [3] Scientists also think the fungal disease chytridiomycosis may have affected this frog's population, as it killed many stream-breeding frogs in Peru. [3]

The edible bullfrog spends approximately 10 months of the year in aestivation beneath the surface of the soil, only emerging to breed in numbers if sufficiently heavy rain, i.e. more than 70 mm (2.8 in), falls within a short period. After which male edible bullfrogs call on the flooded grassland and from any small, temporary pools such as ...
Two main types of reproduction occur in frogs, prolonged breeding and explosive breeding. In the former, adopted by the majority of species, adult frogs at certain times of year assemble at a pond, lake or stream to breed. Many frogs return to the bodies of water in which they developed as larvae.
During the breeding season, males have a “cricket”-like, trilling call, which attracts females. [6] Unlike some dendrobatid frogs, R. vanzolinii parents actively protect and feed their tadpoles. The female will lay a fertile egg (or eggs) in a tiny pool of collected rainwater, typically within the central funnel, or “cup”, of a ...
