Toads of the Family Bufonidae possess neurotoxins (bufadienolides) which are generally considered to be synthesized de novo. Thus, invasive toad species pose a threat native predators via toxic effects. However, influence diet on toxicity is poorly understood. We evaluated effect embryos Bufo japonicus formosus in Japan, using tadpoles (Rana pirica) as bioassay. Specifically, we compared spawne...

Recently, the morphological and molecular features of five stain fungi infecting rubberwood (Hevea brasiliensis), namely Paecilomyces maximus, formosus, Penicillium crustosum, lecythidis Aspergillus chevalieri, have been studied. Prior to this study, authors revealed that catechin from gambir (Uncaria gambir) could inhibit growth white-rot fungus Schizophyllum commune, it was important determin...

Abstract Background The genus Acletoxenus (tribe Gitonini, subfamily Steganinae, family Drosophilidae) is a small widespread genus, comprising only four species worldwide, namely: indicus Malloch, 1929, A. quadristriatus Duda, 1936, meijerei 1924 in addition to formosus (Leow, 1864), the of present study. larvae spp. are known as predators whiteflies. Results and its predaceous 1864) recorded s...

Timber harvest provides favorable habitat for many species of shrub-dependent birds. Because of historical dominance, effect of clearcutting on early successional birds has been widely studied, but less information is available on alternatives such as shelterwood and group selection, which have become a more dominant means of regenerating pines (Pinus spp.) on federal lands of the southeastern ...
