Photobleaching through glass micropipettes: sodium channels without lateral mobility in the sarcolemma of frog skeletal muscle. [PDF]
Proceedings of the National Academy of Sciences, 1982 Sodium currents were recorded from frog skeletal muscle by using fire-polished micropipettes to electrically isolate and voltage clamp a small patch of sarcolemma. Sodium current amplitude served as an assay for the number of functional sodium channels in the patch. With the pipette as a light guide, these channels were irradiated with ultraviolet (UV)

Comparative evaluation of funnel, box, and camera traps for reptile and amphibian inventory
Wildlife Society Bulletin, EarlyView.We used data from 5 herpetological inventories conducted in Florida to evaluate the relative efficacy of funnel, box, and motion‐triggered camera traps for detecting reptile and amphibian species along drift‐fence arrays. Our results suggest that a hybrid array design (funnel traps + central camera trap) is best suited for general herpetofaunal ...

Rediscovery of Hyalinobatrachium chirripoi (Anura: Centrolenidae) in southeastern Costa Rica
Revista de Biología Tropical, 2004 The Suretka glass frog, Hyalinobatrachium chirripoi, has been recently rediscovered in the south-eastern region of Costa Rica. This species was last reported in Costa Rica in the 1950’s. H. chirripoi is distinguished from H. colymbiphyllum, which appears

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)
Integrative Zoology, EarlyView.Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

The oscillatory response of the electroretinogram and neuronal adaptation
Acta Ophthalmologica, EarlyView.Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Context-dependent vocal behavior in a glass frog
Abstract Acoustic communication is fundamental to social interactions in many animal species, allowing individuals to transmit information about identity, reproductive status, and competitive ability. Because call production incurs inherent costs, individuals are expected to modify their vocalizations depending on the

Archaeometry, EarlyView.ABSTRACT Geochemical analysis of five brooch types from the Lower Rhine area dated to the last century bc and first century ad is used to constrain resource use, exchange and mobility. Lead isotope ratios demonstrate an Iberian provenance for copper in bronze Late Iron Age brooches.

Results in OpticsIn this paper, we propose a novel scheme for an all-reflective FROG device using a near-90° retro-reflecting mirror for the complete single-shot measurement of intensity and phase of ultra-short laser pulses.

Conservation Science and Practice, EarlyView.We analyzed delegation size, voting records, and working‐group rosters across five CITES Conferences of the Parties (CoP16–20) to examine how Party‐level traits predict delegation size and how delegation size shapes participation when Committees meet concurrently.
