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

Conservation 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.

Parallel Morphological and Functional Development in the Xenopus Retinotectal System

Developmental 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.

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

Ecology 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.

Evaluating the Use of Environmental DNA as a Method to Determine Occupancy and Distribution of Coeur d'Alene Salamanders in Montana

Ecology and Evolution, Volume 16, Issue 1, January 2026.
The purpose of this project was to evaluate the efficacy of eDNA sampling to determine occupancy of Coeur d'Alene salamanders, an “imperiled” species in Montana. Previous methods used to identify occupied sites were haphazard with no measure of detection probability. Due to the unique habitat used by these salamanders (seeps and waterfall spray zones),

Conjugated Bile Acids Enhance Growth Performance, Liver Health, and Bile Acid Metabolism in Pearl Gentian Grouper Fed a High Plant‐Protein Diet

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
The conjugation states of bile acids (BAs) have been demonstrated to affect BAs regulatory functions. This study aimed to investigate the effects of conjugated or non‐conjugated BA additions on growth performance, liver health, and BA metabolism in pearl gentian grouper (Epinephelus lanceolatus♂ × E.

Removing invasive stream macrofauna shifts nontarget invertebrate mesofauna through facilitation

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Positive interactions among non‐native species can drive invasional meltdowns to the detriment of native biota. Here, we assessed whether targeted control of aquatic invasive species (AIS) can benefit native species by eliminating synergies among invaders.

Developmental Patterns of Hepatic Peroxisome Proliferator‐Activated Receptor (PPAR) Expression in Xenopus laevis and Response to Pharmaceutical Agonists During Metamorphic Climax

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 10, Page 1191-1204, December 2025.
ABSTRACT Peroxisome proliferator‐activated receptors (PPAR) are master transcriptional regulators that maintain metabolic homeostasis in vertebrates. Amphibians are often exposed to endocrine disrupting compounds (EDCs) that could dysregulate lipid metabolism.

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

The Anatomical Record, Volume 308, Issue 11, Page 3053-3062, November 2025.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer
