Parallel metabotropic pathways in the heart of the toad, Bufo marinus.

Food of the Marine Toad, Bufo mavinus, and Six Species of Skink in a Cacao Plantation in New Britain, Papua New Guinea

Food items from the stomachs of the toad Bufo marinus comprised 88 % snails and ants. The main single item of food of the skinks Carlia fusca, Emoia baudinii, E. callisticta, E. mivarti, Lamprolepis smaragdinum and Sphenomorphus jobiensis was lepidopteran larvae.

Lateralisation of predator avoidance responses in three species of toads.

Lateralisation of responses to presentation of a simulated predator was investigated in three species of toads: two European species (the common toad, Bufo bufo, and the green toad, Bufo viridis) and one species introduced to Australia from South America, the cane toad Bufo marinus . First a simulated snake was presented moving rapidly towards the toad in the frontal field of vision and the toa...

Effect of temperature on cardiac vagal action in the toad Bufo marinus.

The effect of temperature on the action of the vagus nerve on the heart was studied in the toad Bufo marinus. Experiments were performed on two groups of toads, in one the heart was perfused at a constant rate with oxygenated Ringer's solution and in the other the circulation was left intact. In all toads there was a linear relationship between pulse interval (PI) and the frequency of vagal sti...

Thermal Dependence of Maximal Ca2+-Activated Force in Skinned Muscle Fibres of the Toad Bufo Marinus Acclimated at Different Temperatures

Acanthocephalus bufonis (Acanthocephala) from Bufo marinus (Bufonidae: Amphibia) in Hawaii.

During a survey of the helminth parasites of the introduced toad, Bufo marinus, on O'ahu, Hawaii, an acanthocephalan corresponding to Acanthocephalus bufonis (Shipley, 1903) was found in the intestinal tract. This is a new host and locality record for A. bufonis which has only previously been recorded from amphibians in the Orient. Possible mechanisms for the introduction of A. bufonis to Hawai...
