Since three bullhead catfish species were introduced to Europe in the late 19th century, they have spread to most European countries. In Hungary, the brown bullhead (Ameiurus nebulosus) was more widespread in the 1970s-1980s, but the black bullhead (Ameiurus melas) has gradually supplanted since their second introduction in 1980. The introgressive hybridization of the two species has been presu...

The Staphylinini genus Ocyolinus Sharp, 1884 is revised. Three species are described as new, O. astenos Chatzimanolis & Ashe sp. n., O. dimoui Chatzimanolis & Ashe sp. n. and O. nebulosus Chatzimanolis & Ashe sp. n., all from Panama. A lectotype is designated for O. rugatus Sharp, 1884 and O. vulneratus Bernhauer, 1906. Ocyolinus vulneratus Bernhauer is placed in synonymy with O. rugatus Sharp....

Two new coffinfishes, Chaunax nebulosus n. sp. and Chaunax africanus n. sp., are described from the Indian Ocean. Both species belong to the C.fimbriatus-species group which is characterised by having filaments on the dorsal head and a complex color pattern on the dorsal surface. They are morphometrically and meristically conservative but differ in coloration. Chaunax nebulosus can be distingui...

An annotated list of Aphrophoridae of Iran is provided, based on examination of specimens housed in the Hayk Mirzayans Insect Museum (Iran) and the National Museum of Wales, Cardiff (UK) and on previously published records. Ten species are now recorded from Iran. An identification key to the genera and species is provided, with illustrations and together with distributions. The subgenus Philaen...

The present study was aimed to analyse the proximate composition and endophytic microbial colonization in six marine fishes such as Nemipterus japonicas, Epinephelus areolatus, Lutjanusquin quelineatus, Scolopsis bimaculatus, Lutjanus decussate and Lethrinus lensus, were collected from Mudasalodai coastal region, Tamil Nadu, South east coast of India. Maximum protein recorted Lethrinus lensus 4...

Abstract The validation of many anuran species is based on a strictly descriptive, morphological analysis small number specimens with limited geographic distribution. Scinax Wagler, 1830 genus controversial group doubtful taxa and taxonomic uncertainties, due high cryptic species. One example the pair constrictus nebulosus, which share similar morphology. restricted to Brazilian Cerrado savanna...

Emerging evidence increasingly illustrates the importance of a holistic, rather than taxon-specific, approach to the study of ecological communities. Considerable resources are expended to manage both introduced and native mammalian carnivores to improve conservation outcomes; however, management can result in unforeseen and sometimes catastrophic outcomes. Varanid lizards are likely to be apex...
