Gustatory sensitivity of an anuran to cantharidin

Experientia, 1990
Glossopharyngeal 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, 1963
AbstractRibonucleic 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, 1985
In 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, 1999
Frogs 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, 2000
The 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, 2007
The 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 ...

Dorsal striatopallidal system in anurans

Journal of Comparative Neurology, 2003
AbstractThe dorsal striatopallidal system of tetrapods consists of the dorsal striatum (caudate‐putamen in mammals) and the dorsal pallidum. Although the existence of striatal and pallidal structures has been well documented in anuran amphibians, the exact boundaries of these structures have so far been a matter of debate.

Morphological characterization of the anuran integument of the Proceratophrys and Odontophrynus genera (Amphibia, Anuran, Leptodactylidae)

Micron, 2007
The morphological characteristics of the leptodactylid integument of Proceratophrys and Odontophrynus genera were investigated by means of stereoscopic, low vacuum scanning electron and light microscopy. The integument surface of Proceratophrys boiei, Proceratophrys laticeps and Proceratophrys appendiculata exhibited several projections, while the ...
