Digital dissection of the model organism Xenopus laevis using contrast-enhanced computed tomography [PDF]

, 2017
The African clawed frog, Xenopus laevis, is one of the most widely used model organisms in biological research. However, the most recent anatomical description of X. laevis was produced nearly a century ago.

Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae). [PDF]

Mol Ecol
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

Patterns of species richness and turnover in endemic amphibians of the Guineo‐Congolian rain forest

Diversity and Distributions, Volume 29, Issue 8, Page 1035-1051, August 2023., 2023
Abstract Aim The African Guineo‐Congolian (GC) region is a global biodiversity hotspot with high species endemism, bioclimatic heterogeneity, complex landscape features, and multiple biogeographic barriers. Bioclimatic and geographic variables influence global patterns of species richness and endemism, but their relative importance varies across taxa ...

Antimicrobial, cytotoxic, and insulin‐releasing activities of the amphibian host‐defense peptide ocellatin‐3N and its L‐lysine‐substituted analogs

Journal of Peptide Science, Volume 29, Issue 4, April 2023., 2023
Substitution of Asp4 by L‐Lys ([A4K]) in the frog skin peptide ocellatin‐3N led to a 4–16‐fold increase in antimicrobial activity against both Gram‐positive and Gram‐negative bacteria and a 2.5–4‐fold increase in cytotoxic potency against human tumor‐derived cells.

A monogenean parasite reveals the widespread translocation of the African clawed frog in its native range

Journal of Applied Ecology, Volume 59, Issue 11, Page 2670-2687, November 2022., 2022
Data from cointroduced, host‐specific parasites, as tags for translocation, can add value to investigations in invasion biology and conservation. A better understanding of the translocation history and resulting genetic mixing of host and parasite lineages in the native range can shed light on the genetic make‐up of parasite assemblages cointroduced to

Fossils Reveal Long-Term Continuous and Parallel Innovation in the Sacro-Caudo-Pelvic Complex of the Highly Aquatic Pipid Frogs

Frontiers in Earth Science, 2019
Within the already peculiar Bauplan of anurans, pipid frogs have evolved an array of bizarre features that are commonly linked to their highly aquatic lifestyle. Among the latter, there are several distinctive sacro-caudo-pelvic features shared by extant

Species composition and distribution of endemic frog species of Keffa, southwest Ethiopia

Global Ecology and Conservation, 2022
The present study was carried out to describe the species composition, diversity, distribution, and species richness of endemic frog species in the Keffa area, southwest Ethiopia. Data were collected during the wet and dry seasons from 2018 to 2021.

Multiple bombesin-like peptides with opposite functions from skin of Odorrana grahami [PDF]

, 2007
Bombesin-like peptides (BLPs) are a family of neuroendocrinic peptides that mediate a variety of biological activities. Three mature BLPs from the skin secretions of the frog Odorrana grahami were purified.

Low structural variation in the host-defense peptide repertoire of the dwarf clawed frog Hymenochirus boettgeri (Pipidae). [PDF]

PLoS ONE, 2014
THE skin secretion of many amphibians contains peptides that are able to kill a broad range of microorganisms (antimicrobial peptides: AMPs) and potentially play a role in innate immune defense. Similar to the toxin arsenals of various animals, amphibian
