Geographical variation of organ size in Andrew’s toad (Bufo andrewsi)

open access: yesFrontiers in Ecology and Evolution, 2022
Phenotypic variation of morphological and physiological traits is assumed to be generated from spatial heterogeneity in environments, and it has been regarded as an important concern domain in evolutionary biology.

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

open access: yesFEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Cloning, characterization, and evolutionary patterns of KCNQ4 genes in anurans

open access: yesEcology and Evolution
Acoustic communication plays important roles in the survival and reproduction of anurans. The perception and discrimination of conspecific sound signals of anurans were always affected by masking background noise.

Regeneration in Hypophysectomized Anuran Tadpoles.

open access: yesExperimental 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.

Programmable DNA‐Peptide Hybrid Nanostructures for Potent Neutralization of Multiple Influenza a Virus Subtypes

open access: yesAdvanced Functional Materials, EarlyView.
A multivalent antiviral platform based on honeycomb‐shaped DNA nanostructures (HC–Urumin) is developed to enhance the potency and breadth of the host defense peptide Urumin. Through spatially patterned trimeric presentation, HC–Urumin disrupts influenza A virus entry, improves cell viability, and reduces disease severity in vivo‐offering a modular and ...

The herpetofauna of the cloud forests of Honduras [PDF]

open access: yes, 2010
The cloud forest amphibians and reptiles constitute the most important herpetofaunal segment in Honduras, due to the prevalence of endemic and Nuclear Middle American-restricted species.

Amphibian chytridiomycosis : a review with focus on fungus-host interactions [PDF]

open access: yes, 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 ...

Charge‐Induced Morphing Gels for Bioinspired Actuation

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel electroactive actuation mechanism that enables the gel material to generate substantial and reversible shape‐changing while preserving topological and isochoric (volumetric) equivalence. The resultant morphing behaviors can mimic the movements of muscle‐driven organelles in nature, including cilia‐like beating and ...
