Quantification of mesocosm fish and amphibian species diversity via environmental DNA metabarcoding
Molecular Ecology Resources, 2015 Freshwater fauna are particularly sensitive to environmental change and disturbance. Management agencies frequently use fish and amphibian biodiversity as indicators of ecosystem health and a way to prioritize and assess management strategies ...

Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots
Advanced Intelligent Systems, EarlyView.Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

The Metamorphosis of Amphibian Toxicogenomics [PDF]
Frontiers in Genetics, 2012 Amphibians are important vertebrates in toxicology often representing both aquatic and terrestrial forms within the life history of the same species. Of the thousands of species, only two have substantial genomics resources: the recently published genome of the Pipid, Xenopus (Silurana) tropicalis, and transcript information (and ongoing genome ...

DuckyDog: An Erect Amphibious Robot with Variable‐Stiffness Legs and Passive Fins
Advanced Intelligent Systems, EarlyView.DuckyDog, a quadruped amphibious robot using erect posture, is proposed with dog‐inspired tendon‐driven compliant legs for walking and paddling, a duck‐inspired body for buoyancy, and passive fins to increase propulsion. It achieves maximum speeds of 0.4 body lengths per second on land and 0.3 on water, demonstrating the ability to navigate in complex ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning
The Anatomical Record, EarlyView.Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

A bibliometric-mapping approach to identifying patterns and trends in amphibian decline research
Acta Herpetologica, 2020 Amphibian decline is one of the most severe and well-documented examples of immediacy of the ongoing biodiversity crisis. In this study we analyze the scientific literature on amphibian declines with a view to identifying and analyzing emerging patterns ...

Epidermal galactose spurs chytrid virulence and predicts amphibian colonization
Nature Communications, 2021 The skin disease chytridiomycosis is linked to global amphibian declines but effective mitigation measures require improved understanding of the mechanisms underpinning the disease ecology.
