Global Trends in Drought Impacts on Wildlife—A Review

open access: yesGlobal Change Biology, Volume 32, Issue 2, February 2026.
We reviewed peer reviewed literature pertaining to instances of anomalous drought (any drought event that deviates from standard conditions (e.g., dry season) when compared to a long term average) and its impacts on wildlife. We summarize the directional effects of drought on wildlife, as well as how drought is quantified across the literature ...

Characterization of the toll‐like receptor 13 homologs in American bullfrogs, Lithobates catesbeianus, and their involvement in antimicrobial immunity

open access: yesJournal of the World Aquaculture Society
Toll‐like receptors (TLRs) are an important family of pattern‐recognition receptors that recognize a series of pathogen‐associated molecular patterns to trigger the host immune response.

Tuning in the bullfrog ear

open access: yesBiophysical Journal, 1988
When electrical resonances were observed in acoustic sensory cells of lower vertebrates, the hearing research community was presented with the exciting possibility that tuning in the ears of those animals might be explained directly in terms of familiar molecular devices.

Non-native Amphibian Pet Trade via Internet in Poland [PDF]

open access: yes, 2018
Overharvesting and trade in amphibian populations is one of the causes of their global decline. Online trade not only encourages the exploitation of an increasing number of rare and endangered amphibian species from all over the world but also ...

Detection and succession properties of forested vernal pools with eDNA metabarcoding

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
We examined the capacity of environmental DNA metabarcoding for studying biodiversity of forested vernal pools, using multiple assays to investigate different eukaryotic communities over space and time. Our results suggest that metabarcoding can serve as a complementary tool for ‘scaling up’ vernal pool biodiversity monitoring, illuminating ecological ...

Ultrasound‐Powered, Battery‐Free Implants via Triboelectric Energy Harvesting

open access: yesAdvanced Materials Technologies, Volume 11, Issue 2, 22 January 2026.
Ultrasound‐driven triboelectric nanogenerators (US‐TENGs) present a promising approach to battery‐free implants by combining body‐safe ultrasound with the material and structural versatility of TENGs. This review categorizes current US‐TENG research into long‐term and transient short‐term applications and discusses key challenges in materials, device ...

DNA barcoding elucidates the new altitude record and range-extension of lesser-known bullfrog (Hoplobatrachus litoralis) in northeast India

open access: yesMitochondrial DNA. Part B. Resources, 2020
The molecular information of lesser-known bullfrog, Hoplobatrachus litoralis is restricted from Bangladesh (type locality) and Myanmar. The morphological observation further evidenced the range-extension of this species from India and Myanmar.
