Vasotocin expression in the preoptic area of frogs Batrachyla under noise exposure
(2016)
In non-mammalian vertebrates, the nonapeptide arginine vasotocin (AVT) is involved in the
modulation of a wide diversity of social behaviors. In anurans, reproductive interactions rely strongly
on acoustic signals. Within ...
Unexpected reproductive fidelity in a polygynous frog
(2020-08-01)
Polygynous mating systems with group fidelity are a common animal organization, typically consisting of multiple females in a mated group with a single male for an extended period (sometimes referred to as harem polygyny). ...
Reproductive Biology of the Critically Endangered Valcheta Frog, Pleurodema somuncurense (Anura: Leptodactylidae), from Patagonia, Argentina
(Sociedade Brasileira de Herpetologia, 2017-12)
Amphibians exhibit a great diversity of reproductive modes. Nevertheless, reproductive biology is still unknown for several threatened Neotropical species, including the Critically Endangered microendemic Valcheta frog, ...
Carrying progeny on the back: reproduction in the Brazilian aquatic frog Pipa carvalhoi
(2011)
Female Pipa carvalhoi incubate their eggs in the skin of the dorsum where the embryos develop until they emerge. Behavioral and morphological aspects of this reproductive mode were studied through courtship until the ...
Ecological aspects about Leptodactylus chaquensis (Anura: Leptodactylidae) from Argentina: trophic, reproductive and parasites features
(British Herpetological Society, 2006-12)
We studied the trophic and reproductive ecology and document the helminth fauna of the Cei’s white-lipped frog, Leptodactylus chaquensis, from north-eastern Argentina. This frog is a generalist predator, using an intermediate ...
Helminth's assemblage of a small frog in the Brazilian semiarid: parasite-host-environment relationships
(Fundacao Zoobotanica Rio Grande Sul, Museu Ciencias Naturais, 2022-01-01)
Parasite infections may contingency different aspects of the hosts' lives, and are usually expected to directly or indirectly compromise host reproduction. However, although amphibians have historically been study models ...
Behavioral and morphological contrasts on the reproduction of two prolonged breeders of the genus Physalaemus (Anura: Leptodactylidae)
(Academia Brasileira de Ciencias, 2020-11)
The reproduction is one of the main events in the life of an organism, and anurans stand out among vertebrates because of the diversity of their reproductive strategies. We studied the reproduction of two syntopic species, ...
Colouration in amphibians as a reflection of nutritional status: The case of tree frogs in Costa Rica
(2017-08-24)
Colouration has been considered a cue for mating success in many species; ornaments in males often are related to carotenoid mobilization towards feathers and/or skin and can signal general health and nutrition status. ...
Alternative reproductive modes of Atlantic forest frogs

Trophic eggs in the foam nests of Leptodactylus labyrinthicus (Anura, Leptodactylidae): An experimental approach
(2005-10-01)
The South American pepper frog, Leptodactylus labyrinthicus, is a large species that lays eggs in foam nests in holes dug out of the banks of different bodies of water. Recently, it was reported that only 6-10% of eggs are ...
