INNERVATION OF THE LARGE INTESTINE OF THE TOAD (BUFO MARINUS) [PDF]

open access: yesBritish Journal of Pharmacology and Chemotherapy, 1964
The morphology, physiology and pharmacology of the innervation of the toad (Bufo marinus) large intestine have been studied. The large intestine can be divided into the regions colon, rectum and cloaca, on morphological grounds, but acts as a unit in response to nerve stimulation.

Helpful invaders: Can cane toads reduce the parasite burdens of native frogs?

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2015
Many invading species have brought devastating parasites and diseases to their new homes, thereby imperiling native taxa. Potentially, though, invaders might have the opposite effect. If they take up parasites that otherwise would infect native taxa, but

Electrical responses of rods in the retina of Bufo marinus

open access: yesThe Journal of Physiology, 1977
1. Intracellular responses to flashes and steps of light have been recorded from the outer segment and the cell body of rods in the retina of the Bufo marinus. The identification of the origin of recorded responses has been confirmed by intracellular marking.2.

slc26a12-A novel member of the slc26 family, is located in tandem with slc26a2 in coelacanths, amphibians, reptiles, and birds. [PDF]

open access: yesPhysiol Rep
Abstract Solute carrier family 26 (Slc26) is a family of anion exchangers with 11 members in mammals (named Slc26a1‐a11). Here, we identified a novel member of the slc26 family, slc26a12, located in tandem with slc26a2 in the genomes of several vertebrate lineages.
