Two amphibian species from China are designated by the specific nomen shuichengensis, which refers to the Shuicheng County (26°34'N, 104°51'E), south of the city of Liupanshui in the province of Guizhou: Megophrys shuichengensis (Amphibia, Anura) and Pseudohynobius shuichengensis (Amphibia, Urodela). The holotypes (holophoronts) of both species were deposited in Department of Biology of the Liu...

Most caecilians are thought to be generalist predators of soil ecosystem engineers (earthworms, termites and ants), but it has been suggested that members of the East African genus Boulengerula are specialist predators. Surprisingly, in the only detailed study of diet of any Boulengerula, the authors speculated thatB. taitanus is partly detritivorous,based on the large amount of organicmatter f...

The outburst of mitotic activity in regenerating tissues of amphibia has been demonstrated by a number of workers.In the series of studies on the above mentioned phenomenon,the writer has reported that mitotic activity in regenerating tissues of the limb and dorsal skin is inhibited by hypophysectomy(Inoue, 1956).To study the results obtained by hypophysectomy,the effects of several hormones on...

Amphibia and its major groups are defined according to principles of phylogenetic taxonomy, and the implications of the definitions for amphibian systematics are discussed. The results of phylogenetic analyses of Amphibia, Anura, Caudata, and Gymnophiona from morphological and molecular studies are compared, based on papers published in the symposium "Amphibian relationships: Phylogenetic analy...

IT is well known that colour changes of animals may be brought about by (a) direct action of light, heat and other stimuli on the skin chromatophores, as, for example, in the "primary" photic response of Amphibia, and (b) action of stimuli on localized receptors. Co-ordinated responses, i.e. responses of the second type, fall into two categories which offer a striking initial contrast in their ...

Complete submergence represses photosynthesis and aerobic respiration, causing rapid mortality in most terrestrial plants. However, some plants have evolved traits allowing them to survive prolonged flooding, such as species of the genus Rorippa, close relatives of Arabidopsis (Arabidopsis thaliana). We studied plant survival, changes in carbohydrate and metabolite concentrations, and transcrip...

That certain hormones as well as neural agencies exert considerable effects upon the mitotic level of normal and regenerating tissues of Amphibia has been claimed from time to time. Denervation was stated to cause some measure of decrease in the mitotic activity of the regenerating tissues of adult newt(Singer and Craven, 1948). The mitotic responsiveness of epidermis of larval Amphibia to impl...
