Repurposing Bird‐Based Acoustic Models for Amphibian Surveys: Strengths and Limitations in Real‐World Deployments

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
In this study, we developed AnuraSearch, an open‐source classifier for 11 Ukrainian amphibian species, by repurposing the avian BirdNET algorithm via transfer learning to process over 18,000 h of autonomous acoustic recordings. Although the model demonstrated high precision and successfully reconstructed detailed seasonal and diel vocal activity ...

Day–night and seasonal variations of a subterranean invertebrate community in the twilight zone

open access: yesSubterranean Biology, 2018
Being characterized by the absence of light and a reduced environmental cyclicity, the subterranean domain is generally regarded as temporally stable.

Diving deeper: Mesopelagic fish biomass estimates comparison using two different models

open access: yesFrontiers in Marine Science, 2023
A growing population on a planet with limited resources demands finding new sources of protein. Hence, fisheries are turning their perspectives towards mesopelagic fish, which have, so far, remained relatively unexploited and poorly studied.

The Twilight Zone of Nucleotide Homology [PDF]

open access: yes, 2019
Homology search tools are important for inferring homology in the abundance of genomes currently sequenced. These tools utilise sequence similarity in order to assign a score between two sequences from which homology is inferred. The relationship between

On the signature of the cirrus twilight zone

open access: yesEnvironmental Research Letters, 2014
Cirrus clouds are known to play a key role in the climate system, but their overall effect on Earth’s radiation budget is not yet fully quantified. The uncertainties are, in part, due to ambiguities in cirrus extent or coverage. Here we show that despite

Cave-Dwelling Populations of the Monstrous Rainfrog (Craugastor pelorus) from Mexico

open access: yesDiversity, 2023
Amphibians are known cave dwellers, and a few anurans have shown to make exploratory or opportunistic use of subterranean environments. We report on the use of karst ecosystems and cavernicolous environments by the monstrous rainfrog Craugastor pelorus ...

Electrification and Child Work: Direct and Spillover Effects in Ethiopia

open access: yesSustainable Development, EarlyView.
ABSTRACT While electrification is often promoted for improving adults' labor supply, its effect on child work remains underexplored. Using four waves of Ethiopian panel data, we examine how electrification affects children's work time. By differentiating between households with and without own electricity access within electrified communities, we ...

Smuggling Sovereignty: Trade, Transgression, and State Authority

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT Global supply chains are saturated with transgressions—corruption, smuggling, document forgery, and other practices that blur the line between legality and illegality. States do not merely endure these practices; they actively shape the conditions for them, producing the very illegal systems they then claim to police.

Unraveling the impact of dog‐friendly spaces on urban–wildland pumas and other wildlife

open access: yesWildlife Biology, EarlyView.
As the most widespread large carnivore on the planet, domestic dogs Canis lupus familiaris can pose a major threat to wildlife, even within protected areas (PAs). Growing human presence in PAs, coupled with increasing pet dog ownership underscores the urgency to understand the influence of dogs on wildlife activity and health.

Photoacclimation and induction of light-enhanced calcification in the mesophotic coral Euphyllia paradivisa [PDF]

open access: yesRoyal Society Open Science, 2019
Corals and their photosymbionts experience inherent changes in light along depth gradients, leading them to have evolved several well-investigated photoacclimation strategies.
