Rapid adaptation to invasive predators overwhelms natural gradients of intraspecific variation

Nature Communications, 2020
Invasive species can influence the evolution of natives. Here, authors use common garden experiments to show that invasive predatory crayfish have homogenized the developmental timing of a native frog by selecting for more rapid development to avoid ...

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

FEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Anti-apoptotic response during anoxia and recovery in a freeze-tolerant wood frog (Rana sylvatica) [PDF]

PeerJ, 2016
The common wood frog, Rana sylvatica, utilizes freeze tolerance as a means of winter survival. Concealed beneath a layer of leaf litter and blanketed by snow, these frogs withstand subzero temperatures by allowing approximately 65–70% of total body water

A Depolarizing Leak in Sodium Bicarbonate Cotransporter NBCe1 Causes Brain Edema

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives SLC4A4 encodes electrogenic sodium bicarbonate cotransporter NBCe1, prominently expressed in kidney and brain. Recessive loss‐of‐function variants in SLC4A4 cause proximal renal tubular acidosis, no brain edema. In the brain, NBCe1 is expressed by astrocytes, where it regulates pH and mediates astrocyte volume changes.

Ferritin Iron Mineralisation: Route of Fe3+ Transfer From the Ferroxidase Centre to the Inner Cavity of Human H‐Chain Ferritin

Angewandte Chemie, EarlyView.
Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.

The lateral stripe – a reliable way for software assisted individual identification for Hyla arborea

Acta Herpetologica
Traditional mark-recapture methods for amphibians and reptiles involve the application of invasive physical markers, such as toe clipping. Photographic identification methods are non-invasive alternative that use natural colouration of individuals for ...

Evolution of pharmacologic specificity in the pregnane X receptor

BMC Evolutionary Biology, 2008
Background The pregnane X receptor (PXR) shows the highest degree of cross-species sequence diversity of any of the vertebrate nuclear hormone receptors. In this study, we determined the pharmacophores for activation of human, mouse, rat, rabbit, chicken,

Confirming Lessona’s brown frogs distribution sketch: Rana temporaria is present on Turin Hills (Piedmont, NW Italy)

Acta Herpetologica, 2020
The presence of Rana temporaria on Turin Hills (Piedmont NW Italy) has been confirmed through morphological and molecular analyses. Breeding individuals of this species were found at two sites and assessed by either morpho-chromatic and genetics.

Designable van der Waals Crystal for Artificial Neuronal Cell Mimicking

Advanced Materials, EarlyView.
Designable van der Waals crystal has been demonstrated for device‐scale neuronal cell mimicking. The structural similarity between ion‐channel in biological membranes and layered vdW lattices is realized with nano‐crystallization via Ar + H2S plasma sulfurization.
