Allometric escape from acoustic constraints is rare for frog calls

open access: yesEcology and Evolution, 2020
Allometric constraint is a product of natural selection and physical laws, particularly with respect to body size and traits constrained by properties thereof, such as metabolism, longevity, and vocal frequency.

WETLAND OCCUPANCY OF POND-BREEDING AMPHIBIANS IN YOSEMITE NATIONAL PARK, USA [PDF]

open access: yes, 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.

Redefining Therapies for Drug‐Resistant Tuberculosis: Synergistic Effects of Antimicrobial Peptides, Nanotechnology, and Computational Design

open access: yesAdvanced Healthcare Materials, EarlyView.
Antimicrobial peptide (AMP)‐loaded nanocarriers provide a multifunctional strategy to combat drug‐resistant Mycobacterium tuberculosis. By enhancing intracellular delivery, bypassing efflux pumps, and disrupting bacterial membranes, this platform restores phagolysosome fusion and macrophage function.

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced 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.

Trade in wild anurans vectors the urodelan pathogen Batrachochytrium salamandrivorans into Europe [PDF]

open access: yes, 2017
Pathogen pollution has caused dramatic losses of amphibian diversity on a global scale. The recently emerged chytrid fungus Batrachochytrium salamandrivorans (Bsal) has been hypothesized to have its origin in Asian urodelan populations, from which it may

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

open access: yesAdvanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Verification on the Impact of Plant Cover Variability to the Anuran Diversity in Bohol, Philippines Using Fractal Analysis

open access: yesRecoletos Multidisciplinary Research Journal, 2014
This study attempted to analyse the impact of the diversity of plant covers of the different sites of Bohol, Philippines to the diversity of Anurans. The researchers utilized a novel method of analysis in the nature of geometrical fractal and statistical

The European Market Remains the Largest Consumer of Frogs’ Legs from Wild Species

open access: yesConservation, 2023
The loss of biodiversity due to overexploitation is well known, but a review and regulation of species used in the frogs’ legs trade has yet to be accomplished.

Sexual dimorphism, fresh water dispersal range, and prey items of Marine toads (Rhinella marina) in Lennox Head, Australia [PDF]

open access: yes, 2012
The invasive cane or marine toad (Rhinella marina) has spread across much of Australia since its initial introduction in 1935. Naturally found in Central and South America, R.
