Hibiscadelphus stellatus H. Oppenheimer, Bustamente, & Perlman, sp. nov., a new, narrowly endemic species from West Maui, Hawaiian Islands is described, illustrated and its affinities and conservation status are discussed. It is currently known from three populations totaling 99 plants in Kaua`ula valley on leeward western Maui. It differs from H. wilderianus, its nearest congener, in its dense...

fecundity is one of the important indicators of reproduction biology in fishes especially in rearing and restocking management of endangered species such as sturgeon. the fecundity of stellate sturgeon (acipenser stellatus pallas, 1771) was studied in 50 specimens captured by gill net (mesh size= 100 mm) and seine net in different fishing areas along the southeastern part of the caspian sea fro...

Stellate sturgeon (Acipenser stellatus) is a species of great conservation concern throughout its range. Over the past century, it has experienced dramatic decline in abundance and distribution Black Sea basin. Information regarding genetic structure very limited region, despite crucial importance for developing adequate management plans species’ recovery. Samples from 163 A. stellatus were ana...

Asteltoxins belong to a group of polyene pyrone mycotoxins that are known be potent inhibitors mitochondrial ATP synthesis and hydrolysis. Asteltoxin A was first isolated from the toxic maize cultures Aspergillus stellatus. Several attempts have been made synthesize asteltoxin A, starting with bis(tetrahydrofuran) moiety has demonstrated previously in biosynthetic studies. This review highlight...

Abstract On the basis of in situ analysis sturgeon condition within Lower Danube River, aim was to carry out a research that would complement results obtained from monitoring and ultrasonic tagging methods. Thus, DNA samples were taken selectively each ultrasonically tagged specimen order determine whether or not there is possibility hybridization between species Acipenser stellatus Huso huso ....

A new gregarious braconid parasitoid wasp of Euphorinae, Meteorus stellatus Fujie, Shimizu & Maeto sp. nov. , is described from the Ryukyu Islands in Japan, based on an integrative taxonomic framework. The phylogenetic position species within Meteorini was analyzed DNA fragments mitochondrial cytochrome c oxidase 1 (CO1) and nuclear 28S rDNA genes. recovered as a member versicolor compl...

BACKGROUND More fish have been afforded US Endangered Species Act protection than any other vertebrate taxonomic group, and none has been designated as recovered. Shortnose sturgeon (Acipenser brevirostrum) occupy large rivers and estuaries along the Atlantic coast of North America, and the species has been protected by the US Endangered Species Act since its enactment. METHODOLOGY/PRINCIPAL ...
