Contact us if you are interested in writing for AmphibiaWeb.This species was featured as News of the Week:January 8, 2019: Sex role reversal, in which the time, effort and risk invested in offspring by male parents exceeds that of females, is a rare phenomenon with important implications for sexual selection theory. Under sex role reversal, males invest so much time and effort into caring for offspring that they become a limiting resource for females, and females actively compete for access to potential mates. Previous research has identified sex role reversal in a few birds (e.g. jacanas) and insects (e.g. Australian kaytidids in the family Tettigoniidae). In amphibians, evidence has been sparse. In the Majorcan midwife toad, males care for clutches of eggs wrapped around their legs, and there is some evidence that females actively court and compete for males. New research provides evidence that sex role reversal may occur in Palawan Wart Frog from Borneo, Limnonectes palavensis. Goyes Vallejos et al. (2017) found that female Limnonectes palavensis called more frequently than males, and that multiple females would approach individual males and call to them. Subsequently Goyes Vallejos et al. (2018) demonstrate that males spend long periods of time caring for their offspring. They do not attempt to leave the area or search for new mates while caring for a clutch. While further evidence is needed to conclusively demonstrate sex role reversal, this species provides one of the best candidates for this phenomenon in frogs to date. (Written by Kyle Summers)August 14, 2017: Frog calls are typically only produced by males, with the females of some species occasionally responding. However, while studying Limnonectes palavanensis, Vallejo et al. (2017) found that advertisement calls were primarily produced by females. Males also had advertisement and courtship calls, but they only produced them sporadically. The authors also found that females aggregate and call around a single male in a lek-like formation in which the male chooses a female. Lastly, after laying eggs, females leave males to guard eggs and transport tadpoles. All of these behaviors together demonstrate the first known instance of a sex-role-reversal mating system in amphibians. (Written by Ann Chang)

Limnonectes palavanensis

provided by wikipedia EN

Limnonectes palavanensis (common names: smooth guardian frog, Palawan wart frog) is a species of frog in the family Dicroglossidae. It is found in the Palawan Island (the Philippines, its type locality) and in Borneo (Brunei, Indonesia, Malaysia).[3][4] The species shows paternal care,[2][4] a relatively rare trait in frogs.[5]

Description

Male Limnonectes palavanensis grow to about 30 mm (1.2 in) and females to about 40 mm (1.6 in) in snout–vent length. There is a V-shaped ridge between the shoulders, and a sharp interorbital band that separates the anterior part of the head from differently colorer back. Juveniles have a medial vertebral stripe that in some populations persists in adults too.[4]

The tadpole is moderately flat (dorsoventrally compressed). The tail is twice the length of the body. The tail fin is low and ends in a pointed tip.[4]

Reproduction

The male of this species guard the tadpoles that hatch from the eggs laid on the ground. The male then carries the tadpoles on its back to water.[2][4]

Habitat and conservation

Its natural habitats are lower montane and lowland forests. The tadpoles develop in small rain pools[2] and quiet sections of small, slow moving streams.[4]

The habitat of this species is mostly well protected, although it can potentially be impacted by habitat loss.[2] It occurs in the Crocker Range National Park.[1]
