Cross‐continental zero‐shot anuran call classification with CLAP and denoising‐based synthetic embedding generation

Ysobel Sims, Oliver W. Kelly, Andrea S. Griffin, Eric Johns et autres

Abstract Using machine learning models to classify bioacoustic signals of animal species is increasingly important for conservation monitoring because manual expert labelling is time‐consuming and tedious. Monitoring endangered species is particularly challenging because these species are rare, making it difficult to collect …

The refugial squeeze: a globally relevant mechanism of species decline revealed by a threatened amphibian

Kate Tunstill, Matthew Hayward, Hannah Power, Darren Southwell et autres

Aim A key outcome of the global biodiversity crisis is the contraction and range shift of species distribution into refugial habitats that afford some level of protection against threatening processes. Range contractions driven by spatially overlapping threats may fragment populations to the …

Chytridiomycosis infection and heat compromise sperm quality in a threatened frog

Rose M. O. Upton, Anne Ibbotson, Kaya Klop‐Toker, Lachlan Campbell et autres

Environmental change is reshaping wildlife reproduction through increasing temperatures and often leads to the spread of emerging infectious diseases, yet the physiological consequences of managing these stressors remain poorly understood. Amphibians are particularly vulnerable owing to their ectothermy and high susceptibility to …

Harnessing edge computing and citizen science: A new prototype design for continental‐scale acoustic monitoring in Australia and beyond

Andrea S. Griffin, Oliver W. Kelly, Eric Johns, Stephan K. Chalup et autres

Abstract Inadequate monitoring of biodiversity is a characteristic of conservation the world over. The potential of acoustic monitoring is compelling, although the challenges remain substantial. Effective solutions require transdisciplinary collaboration among stakeholders, a focus on open‐source development, and flexible, multipronged technical approaches. …

Assessing Genetic Diversity and Inbreeding Effects in an Endangered Amphibian: Effects of Ecological Restoration and Stochasticity

Nadine Nolan, Sarah E. Stock, Alex Callen, Matt W. Hayward et autres

ABSTRACT The application of population genetic metrics to evaluate the health of a population after undergoing anthropogenic management and experiencing environmental stochasticity remains underexplored in amphibians. Several metrics can be used to measure loss of genetic diversity and decreased gene flow to …

Guess Who: Delineating Post‐Metamorphic Amphibian Life Stages and Sexes Using a Standardised Visible Approach

John Gould, Loren L. Fardell, Alex Callen, Colin R. McHenry

Among animals, adulthood is synonymous with sexual maturity and often defined by the capacity of an individual to store and/or use functional gametes. Yet, under field conditions, where evidence of gametes cannot always be easily ascertained, researchers rely on other cues of …

Avoid Sacrificing Nature to Truly Achieve Net Zero

Charlotte Rigolot, Krishna Pavan Komanduri, Adam S. Smart, Kaya Klop-Toker et autres

ABSTRACT Governments globally have committed to Nature Positive, measurable gains in ecosystem health, and Net Zero, a balance where greenhouse gas emissions are equal to the emissions removed from the atmosphere, thereby addressing the interconnected crises of biodiversity loss and climate change. …
