High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Identification and determination of the absolute configuration of amorph-4-en-10β-ol, a cadinol-type sesquiterpene from the scent glands of the African reed frog Hyperolius cinnamomeoventris

open access: yesBeilstein Journal of Organic Chemistry, 2023
Hyperolid reed frogs are one of the few families of Anurans known to possess glands that emit volatile compounds used in chemical communication. Hyperolius cinnamomeoventris, a model species, possesses a gular gland on its vocal sac that emits chemicals,

The phylogeny of Dendropsophini (Anura: Hylidae: Hylinae)

open access: yesCladistics, 2020
AbstractThe relationships of the hyline tribe Dendropsophini remain poorly studied, with most published analyses dealing with few of the species groups ofDendropsophus. In order to test the monophyly of Dendropsophini, its genera, and the species groups currently recognized inDendropsophus, we performed a total evidence phylogenetic analysis.

Ovulation and Oviposition in Anura [PDF]

open access: yesJournal of Experimental Biology, 1941
ABSTRACT The normal rhythm of sexual activity of both Xenopus and Rana is controlled by secretions of the anterior lobe pituitary. Progesterone and testosterone, as well as extracts of A.L.P., evoke ovulation in normal and hypophysectomized Xenopus.

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

open access: yesAnimal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...

Adaptive capacity of alpine fauna in Australia

open access: yesConservation Science and Practice, EarlyView.
Assessment of adaptive capacity can provide insights into the mechanisms behind the vulnerability of some of Australia's most threatened species to climate change, such as the endangered mountain pygmy possum (Burramys parvus). Our results highlight diversity in the adaptive capacity of Australia's alpine animals and suggest that climate change will ...
