Meteorology and geography, more than biological traits, drive variation in frog phenology across decades

open access: yesEcology, Volume 107, Issue 5, May 2026.
Abstract The fate of a species is a function of interacting environmental and biological processes. Disentangling the roles and interactions of such processes can elucidate the breadth of possible responses to global change, for instance, the potential for phenotypic plasticity or trait evolution to rescue populations from climate change.

Artificial sensory and motor nervous systems enabled by bioinspired nanowire heterostructure synapse

open access: yesInfoMat, Volume 8, Issue 5, May 2026.
A p‐i‐n heterostructured junction synaptic transistor was fabricated, composed of poly(3‐hexylthiophene‐2,5‐diyl) nanowire thin‐film/poly(methyl methacrylate)/ZnO nanowires (PZJ STs), which can emulate biological sensory and motor nervous systems.

Multiple Overspill Flood Channels from Young Craters Require Surface Melting and Hundreds of Meters of Midlatitude Ice Late in Mars’s History

open access: yesThe Planetary Science Journal
Mars’s tadpole craters are small, young craters whose crater rims are incised by one or more exit breaches but lack visible inlets. The tadpole-forming climate records the poorly understood drying of Mars since the Early Hesperian.

The tadpole of Hypsiboas leptolineatus (Braun and Braun, 1977), a species in the Hypsiboas polytaenius clade (Anura; Hylidae)

open access: yesBrazilian Journal of Biology
The larval morphology of Hypsiboas leptolineatus was studied. The tadpole has an ovoid body in lateral view, wider than deep; snout rounded with dorsal reniform nostrils; spiracle sinistral with lateral wall attached to body; anal tube dextral; tail fins

Fins are relevant non-lethal surrogates for muscle to measure stable isotopes in amphibians

open access: yesKnowledge and Management of Aquatic Ecosystems, 2019
Stable isotope analyses (SIA) are now widely used in ecology research to quantify the trophic implications of a large range of ecological processes.

Scale of herpetofauna mitigation translocation in British Columbia, Canada

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Mitigation translocation is widely used across British Columbia to move amphibians and reptiles away from development. Reviewing permits from 2019–2022, we found that more than 5 million individuals, mostly larval western toads, were relocated. Yet almost no monitoring occurs, leaving outcomes unknown.

Radiographic evaluation of gastroliths in a group of 49 juvenile saltwater crocodiles (Crocodylus porosus) in the UK

open access: yesVeterinary Record, Volume 198, Issue 8, Page e343-e350, 18/25 April 2026.
Abstract Background Gastrolith ingestion is a known inherent behaviour in crocodiles. However, the interpretation of coelomic radiographs in crocodilians is challenging due to the limited informative literature in this field. Methods Dorsoventral coelomic radiographs of 49 juvenile saltwater crocodiles (Crocodylus porosus) were acquired twice, with an ...

Vulnerability and behavioral responses of South Chinese anuran tadpoles to native dragonfly (Pantala flavescens) naiads and introduced western mosquitofish (Gambusia affinis)

open access: yesJournal of Freshwater Ecology, 2017
Anti-predator behavior is an important fitness component in most animals. Alien predator species are a serious threat to amphibian populations. We studied the vulnerability and behavioral defenses of tadpoles of six Chinese anurans in response to the ...

Survey of mercury in boreal chorus frog (Pseudacris maculata) and wood frog (Rana sylvatica) tadpoles from wetland ponds in the Prairie Pothole Region of Canada

open access: yesFACETS, 2017
Tadpoles are important prey items for many aquatic organisms and often represent the largest vertebrate biomass in many fishless wetland ecosystems. Neurotoxic mercury (Hg) can, at elevated levels, decrease growth, lower survival, and cause developmental
