Neuroethology of sound localization in anurans
Journal of Comparative Physiology A, 2022Albert Feng pioneered the study of neuroethology of sound localization in anurans by combining behavioral experiments on phonotaxis with detailed investigations of neural processing of sound direction from the periphery to the central nervous system.

Experientia, 1964
L'hypocorde des Anoures est d'origine endodermique. Sa reaction a la phosphatase alcaline s'accroit graduellement jusqu'a l'apparition des vacuoles. Au cours de sa fusion avec le canal perichondral, une reaction a l'enzyme s'observe a la surface externe de la membrane cellulaire. L'hypocorde peut aussi contribuer a la formation des vertebres.

Dermal ossifications-- osteoderms- are more common in anurans than has been gen- erally acknowledged. In the hylid Phyllomedusa bicolor osteoderms are located in the dermis, cover the dorsal surface of the head and body, and are scattered on the lateral and ventral surfaces and the limbs.

Gustatory sensitivity of an anuran to cantharidin
Experientia, 1990Glossopharyngeal nerve stimulation of the bullfrog, Rana catesbeiana, revealed responsiveness to low levels of cantharidin (1.3 x 10(-6) M), providing a first demonstration of neural gustatory sensitivity of an animal to this defensive chemical from blister beetles (Meloidae).

Cellular differentiation in the anuran pronephros
The Anatomical Record, 1963AbstractRibonucleic acid (RNA) is detectable histochemically by means of methyl green pyronin staining (controlled with ribonuclease) in the cytoplasm of the proximal tubules of the frog (Rana pipiens). This is seen at Shumway stage 23 when the proximal tubules become differentiated from the remainder of the tubular complex.

Association of anurans with pathogenic fungi
Mycopathologia, 1985In a study of 450 Amazonian anurans, we isolated yeasts and yeast-like fungi from 54 animals (Bufo granulosus, B. marinus, Dendrophrynyscus sp., Hyla geographica, H. lanciformes, Ololygon rubra, Adenomera hylaedactyla, Eleutherodactylus fenestratus, Leptodactylus fuscus, L. ocellatus, L. pentadactylus). The internal organs of these animals did not show

Allometry in vestibular responses of anurans
Advances in Space Research, 1999Frogs and toads turn either their heads or bodies opposite to angular accelerations applied around the yaw axis. Thresholds exist for the minimum angular acceleration that induces this vestibulomotor response in individual frogs. These thresholds were recorded for several anuran species that cover a broad range of sizes and life styles.

Chemoarchitecture of the anuran auditory midbrain
Brain Research Reviews, 2000The anuran torus semicircularis consists of several subnuclei that are part of the ascending auditory pathway as well as audiomotor interface structures. Additionally, recent anatomical studies suggest that the midbrain tegmentum is an integral part of the audiomotor network.

Control of breathing in anuran amphibians
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007The primary role of the respiratory system is to ensure adequate tissue oxygenation, eliminate carbon dioxide and help to regulate acid-base status. To maintain this homeostasis, amphibians possess an array of receptors located at peripheral and central chemoreceptive sites that sense respiration-related variables in both internal and external ...
