Animals, 2023 Disruptive selection arises when extreme phenotypes have a fitness advantage compared to more-intermediate phenotypes. Theory and evidence suggest that intraspecific resource competition is a key driver of disruptive selection. However, while competition

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]
, 2015 Amphibian declines and extinctions are emblematic for the current sixth mass extinction event. Infectious drivers of these declines include the recently emerged fungal pathogens Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans ...

Regeneration in Hypophysectomized Anuran Tadpoles.
Experimental Biology and Medicine, 1960 Summary1. A comparison was made between regenerating tail-tips in normal and hypophysectomized Rana pipiens tadpoles. 2. No significant differences were noted in amount of regeneration/unit time or in the histology of regenerates. 3. Age of the hypophysectomized animal had no discernible effect on tail-tip regeneration. 4.

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.

The island rule in the Brazilian frog Phyllodytes luteolus (Anura: Hylidae): incipient gigantism?
Zoologia (Curitiba), 2015 The island rule suggests that, when mainland animals are isolated on islands, large animals tend to become smaller, while small animals tend to become larger.

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

WETLAND OCCUPANCY OF POND-BREEDING AMPHIBIANS IN YOSEMITE NATIONAL PARK, USA [PDF]
, 2015 We estimated wetland occupancy and population trends for three species of pond-breeding anurans in Yosemite National Park from 2007 – 2011. We used a double survey technique in which two observers independently surveyed each site on the same day.

Sampling design may obscure species–area relationships in landscape-scale field studies [PDF]
, 2020 We investigated 1) the role of area per se in explaining anuran species richness on reservoir forest islands, after controlling for several confounding factors.

Advanced Materials Technologies, EarlyView.This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...
