‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

open access: yesWildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Bice Salts of Anura

open access: yesChemical and Pharmaceutical Bulletin, 1973
Bile salts of six different species of the Anura were investigated by means of thin-layer chromatography, gas-liquid chromatography, and mass spectrometry. Bile of Xenopus laevis contained taurine-conjugated and free forms of 3α, 7α, 12α-trihydroxy-5β-cholestanoic acid and 5β-cyprinol sulfate2) as its chief constituents.

Egg clutch structure of Rhinella rumbolli (Anura: Bufonidae), a toad from the Yungas of Argentina, with a review of the reproductive diversity in Rhinella [PDF]

open access: yes, 2015
Rhinella rumbolli is a poorly known, medium-sized toad endemic to the Yungas of Argentina. Recent fieldwork allowed observing its peculiar oviposition mode, which is described in this paper.

Pathogenic fungus in feral populations of the invasive North American bullfrog in Argentina [PDF]

open access: yes, 2017
Nearly a third (32.4%) of the world?s amphibian species are either threatened with extinction or already extinct (1). The chytrid fungus Batrachochytrium dendrobatidis (Bd) (Chytridiomycetes: Ryzophydiales) (2) has been recognized as responsible for mass

Effects of complex soundscapes on the occurrence of Anaxipha pallidula in isolated green spaces in Tokyo

open access: yesWildlife Biology, EarlyView.
Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.

Cane toads lack physiological enhancements for dispersal at the invasive front in Northern Australia

open access: yesBiology Open, 2011
Summary Many invasive species have evolved behavioural and morphological characteristics that facilitate their dispersal into new areas, but it is unclear how selection on this level of the phenotype filters through to the underlying physiology.

The tadpole of Physalaemus fernandezae (Anura: Leptodactylidae) [PDF]

open access: yes, 2006
This paper describes the external and buccopharyngeal morphology, chondrocranium and cranial muscles in tadpoles of Physalaemus fernandezae. The data are compared with those for other species of Physalaemus to improve the diagnosis of the “species group”

The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

open access: yesIntegrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.
