Buergeria robusta (Boulenger, 1909)

Species Identity

Buergeria robusta is a species of medium to large-sized treefrog.

Size

Individuals have stocky bodies: males reach 4–5 cm (1.6–2.0 in) in snout-vent length, while females reach 7–8 cm (2.8–3.1 in).

Dorsal Skin and Coloration

The skin on their dorsum is smooth, and their body color changes to match their environment, ranging from brown or gray to greenish, and even yellow.

Breeding Season and Mating Behavior

Their breeding season runs from February to September; during this time, males sit on top of rocks and call to attract mates.

Oviposition

Females deposit eggs directly into water, and do not build foam nests for their eggs.

Endemic Range and Common Name

This species is endemic to Taiwan, where it is called the brown tree frog.

Habitat and Altitudinal Range

It is a common, widespread species found at low to medium altitudes, and lives primarily near creeks or streams.

Threats

It is locally threatened by habitat loss, and is also collected for human consumption.

Genetic Distribution

The genetic distribution of Buergeria robusta matches Taiwan's topography closely, with populations on the eastern and western sides of the Central Mountain Range showing prominent genetic divergence.
