Further experiences with the male-toad pregnancy test using European species.

The comparative sensitivity of the male toad pregnancy test and the Friedman test.

Comparative Series A series of 452 comparisons was made in this laboratory between the Galli Mainini pregnancy test, using the English male toad, Bufo bufo, and routine Friedman pregnancy tests. The latter were made in this laboratory by Dr. A. L. Taylor, and in the University of Bristol Department of Preventive Medicine by Professor K. E. Cooper. The series covered the period from March, 1950,...

Evaluation of sexual dimorphism on the basis of morphometric traits in Talysh toad, Bufo eichwaldi (Litvinchuk, Borkin, Skorinov & Rosanov, 2008), along with the evaluation of the conservation status of the species

The status of sexual dimorphism patterns in human and various animal groups including some mammals, birds, reptiles and amphibians have been studied, however, despite the fact that a growing number of studies were aimed to describe sexual dimorphism patterns in external morphological features such as the proportion of toes in animals, our knowledge of some basic issues, specially in some animal...

Studies on Sex Hormones. Part I. Sperm Test of pregnancy Utilizing Male Toad, Bufo melanostictus Schneid., as Test Animal

Rod pigment and rod noise in the European toad Bufo bufo

Behavioural experiments and ganglion cell recordings indicate that the visual sensitivity of dark-adapted toads is limited by the occurrence of spontaneous isomerization-like noise events in the rods. The frequency of these "false photons" has previously been studied (with micropipette recording) in the toad species Bufo marinus, while the behavioural thresholds were determined using Bufo bufo ...

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...
