FROGS AND TOADSWHEN amphibian eggs are exposed to a temperature shock a few minutes after fertilization, the second maturation division may be suppressed, and, by fusion of the haploid sperm with the diploid egg nucleus, triploid embryos may result 1,2 . In the earliest experiments of this ...
Heliothermy is especially common among frogs and toads: it allows them to increase their body temperature by more than 10°C. The Andean toad Bufo spinulosus exposes itself immediately after sunrise on moist ground and attains its preferred body temperature by this means, long before either ...

A deadly disease that is wiping out the world’s frogs and toads probably originated in the Korean peninsula. The disease is being spread by the pet trade, so banning the trade in amphibians from south-east Asia could help slow it down....

frogs14and Iberian midwife toads15inhabiting areas unfavorable for sound propagation are transmitted better in both native and foreign environments than the calls of conspecifics inhabiting sound favorable habitats. The analyses performed in the current study were not aimed at comparing propagation ...

The evolution of Arabian bufonids and their close relatives remains a challenging biogeographic and taxonomic problem, and it is unknown if the unassigned Arabian toads are derived from African, Southwest Asian, or Western Eurasian lineages, or are the result of in-situ diversification on the Penins...
