Two new Pandanus frogs (Guibemantis: Mantellidae: Anura) from northern Madagascar

open access: yesEuropean Journal of Taxonomy, 2018
We describe two new frog species of the genus Guibemantis Dubois, 1992 (Mantellidae) from northern Madagascar. Both species are placed in the subgenus Pandanusicola Glaw & Vences, 1994 and, like most of their relatives, appear to only inhabit the leaf ...

The mitochondrial genomes of three species of poison frogs (Anura: Dendrobates)

open access: yesMitochondrial DNA. Part B. Resources, 2017
We reconstructed nearly complete mitogenomes for three species of poison frogs, Dendrobates auratus, D. leucomelas, and D. tinctorius, from RNAseq data. We recovered the 13 protein-coding genes, 22 tRNA genes (except tRNA-Val for D.

Species‐specific habitat preferences do not shape the structure of a crested newt hybrid zone (Triturus cristatus x T. carnifex)

open access: yesEcology and Evolution, 2019
Reproductive isolation barriers maintain the integrity of species by preventing interspecific gene flow. They involve temporal, habitat or behavioral isolation acting before fertilization, and postzygotic isolation manifested as hybrid mortality or ...

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

open access: yesAdvanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.
