Ferns and their allies also known as the vascular cryptogamic plants have enormous aesthetic value and multifarious scope for exploring the bioactive molecules against various pathogenic causal organisms of bacterial, fungal and microbial origins. In view of the evolutionary trends of plants the Pteridophytes have valuable importance to unearth the number of uncertain hypothesis of evolution. I...

A new subgenus and three new species of oribatid mites of the genus Yoshiobodes, Yoshiobodes (Dongnaiobodes) subgen. nov., Y. (D.) hexasetosus sp. nov., Y. (D.) biconcavus sp. nov. and Y. (Yoshiobodes) neotrichorostralis sp. nov., are described from southern Vietnam. Yoshiobodes (Dongnaiobodes) subgen. nov. differs from the other subgenera, Yoshiobodes (Yoshiobodes) and Yoshiobodes (Berndobodes...

I recently published a survey of the different meanings of the nomen Amphibia in taxonomic publications since 1758 (Dubois 2015). The 'meaning' of a nomen in zoological nomenclature depends on the system used for the allocation of nomina to taxa, and several such systems can be used (see e.g. Dubois 2006a-b).
