Further experiences with the male-toad pregnancy test using European species.
The satisfactory reports on the Galli Mainini male toad test for pregnancy which have been published from nearly every part of the world (Cowie, 1948 ; Bhaduri, 1951) show that the test can be performed on species of toads or frogs indigenous to the district where the laboratory is situated. In England and Europe the toads Bufo bufo (syn. B. vulgaris) and B. calamita and the frog Rana esculenta...
متن کاملEvaluation 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...
متن کاملThe comparative sensitivity of the male toad pregnancy test and the Friedman test.

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,...
متن کاملDeep genetic structure and ecological divergence in a widespread human commensal toad.
The Asian common toad (Duttaphrynus melanostictus) is a human commensal species that occupies a wide variety of habitats across tropical Southeast Asia. We test the hypothesis that genetic variation in D. melanostictus is weakly associated with geography owing to natural and human-mediated dispersal facilitated by its commensal nature. Phylogenetic and population genetic analyses of mitochondri...
متن کاملARPN Journal of Science and Technology:: Corticosterone as Inhibitor of Bufo Melanostictus Tadpole Growth
This investigation reports the effect of corticosterone on the growth of Bufo melanostictus tadpoles. Test tadpoles of experiment I (T-I), maintained in 1μg/ml solution of corticosterone, were 2.39mm shorter than controls by day 11. Test tadpoles of experiment II (T-II), maintained in 5μg/ml solution were 4.32mm shorter than their counterparts. Growth inhibition was dose related and became sign...
