Slow synaptic transmission in frog sympathetic ganglia [PDF]

open access: yes, 1986
Bullfrog ganglia contain two classes of neurone, B and C cells, which receive different inputs and exhibit different slow synaptic potentials. B cells, to which most effort has been directed, possess slow and late slow EPSPs.

Regulation of intracellular cyclic GMP concentration by light and calcium in electropermeabilized rod photoreceptors. [PDF]

open access: yes, 1994
This study examines the regulation of cGMP by illumination and by calcium during signal transduction in vertebrate retinal photoreceptor cells. We employed an electropermeabilized rod outer segment (EP-ROS) preparation which permits perfusion of low ...

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Making Learning Personally Relevant: Sensemaking Assets Used in Families' Discussions While Using a Pollinator‐Focused Mobile Augmented Reality App

open access: yesScience Education, Volume 110, Issue 2, Page 525-542, March 2026.
ABSTRACT This study seeks to better understand the unique sensemaking assets that rural families weave into their outdoor learning experience while using a location‐based mobile app focused on healthy habitats for solitary bees. The project included mobile augmented reality (AR) technologies, which are increasingly used as educational tools at informal

Direct mechanical stimulation of tip links in hair cells through DNA tethers

open access: yeseLife, 2016
Mechanoelectrical transduction by hair cells commences with hair-bundle deflection, which is postulated to tense filamentous tip links connected to transduction channels.

The Effect of Background Colour on Behaviour and Development of Golden Mantella (Mantella aurantiaca) Tadpoles

open access: yesEthology, Volume 132, Issue 3, Page 204-215, March 2026.
This study examined how background colour influences behaviour and development in golden mantella (Mantella aurantiaca) tadpoles across ontogeny. Tadpoles preferred darker backgrounds, and this preference got less strong with increasing age. Individuals reared in darker conditions were less active but did not differ in growth rate and shelter use when ...

Desenvolvimento de girinos de rã-touro (Rana catesbeiana, Shaw, 1802) cultivados em diferentes densidades de estocagem em tanques-rede Development of bullfrog (Rana Catesbeiana, Shaw, 1802) tadpoles reared at different stocking densities in net tanks

open access: yesRevista Brasileira de Zootecnia, 2004
Objetivou-se, nesta pesquisa, avaliar o efeito da densidade de estocagem sobre o desenvolvimento de girinos de rã-touro em tanques-rede. Foram utilizados 360 girinos com peso médio inicial 0,01g e comprimento inicial médio de 0,92±0,06 cm, distribuídos ...

New insights in gill/buccal rhythm spiking activity and CO2 sensitivity in pre- and post-metamorphic tadpoles (Pelophylax ridibundus)

open access: yes, 2013
Central CO2chemosensitivity is crucial for all air-breathing vertebrates and raises the question of itsrole in ventilatory rhythmogenesis. In this study, neurograms of ventilatory motor outputs recorded infacial nerve of premetamorphic and ...

Simulated soundscapes and transfer learning boost the performance of acoustic classifiers under data scarcity

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 2, Page 322-338, February 2026.
Abstract The biodiversity crisis necessitates spatially extensive methods to monitor multiple taxonomic groups for evidence of change in response to evolving environmental conditions. Programs that combine passive acoustic monitoring and machine learning are increasingly used to meet this need. These methods require large, annotated datasets, which are

Physiological Responses of Juvenile Bullfrogs (Aquarana catesbeiana) to Salinity Stress

open access: yesAnimals
Bullfrogs (Aquarana catesbeiana) are increasingly farmed for their high nutritional value and adaptability to intensive aquaculture systems. However, salinity stress due to environmental changes and habitat salinization poses a significant challenge for ...
