Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

open access: yesThe Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Long‐term impacts of the invasive frog Polypedates megacephalus on Taiwan's native frogs: A 16‐year community science study

open access: yesConservation Science and Practice, Volume 8, Issue 2, February 2026.
Using 16 years of community science data from Taiwan, this study found that habitat specialists and species overlapping ecologically with the invasive frog Polypedates megacephalus declined more than generalists. While declines were higher at sites with P.

Biomonitoring of the genotoxic potential (micronucleus assay) and detoxifying activity (EROD induction) in the River Dadou (France), using the amphibian Xenopus laevis [PDF]

open access: yes, 2004
Within the framework of a general survey of the water quality of the river Dadou (Tarn, France), different physicochemical parameters were measured and an inventory of the fish population was made along the water course, around the Rassisse dam.With the ...

Parallel Morphological and Functional Development in the Xenopus Retinotectal System

open access: yesDevelopmental Neurobiology, Volume 86, Issue 1, January 2026.
ABSTRACT The retinotectal projection in Xenopus laevis is topographically organized. During the early development of the Xenopus visual system, the optic tectum increases considerably in volume, and retinotectal axons and dendrites undergo extensive activity‐dependent remodeling.

An Analysis of pH Tolerance and Substrate Preference of Isolated Skeletal Muscle Mitochondria from Bufo marinus and Rana catesbeiana

open access: yes, 1993
1. The effects of varying pH and substrate on isolated skeletal muscle mitochondria from Bufo marinus and Rana catesbeiana were investigated. 2. For both species, V02 max significantly decreased at all pH\u3c7.3 (P \u3c 0.05), while maximum values were ...

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

open access: yes, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Monitoring the Prevalence and Distribution of Chytrid Fungus (Batrachochytrium dendrobatidis) in the Kihansi Spray Toad (Nectophrynoides asperginis) Population in the Kihansi Gorge Spray Wetlands, Tanzania

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
How to manage the continued impact of Chytrid fungus on Kihansi Spray Toad population in the wild. ABSTRACT Chytridiomycosis, caused by the fungus Batrachochytrium dendrobatidis (Bd), is fatal to some amphibian species, whereas others can carry the pathogen without developing disease.
