Despite low genetic diversity, polar bear abundance is not at risk from inbreeding depression based on their long history of stable population size. Polar bear subpopulations are divided into management groups that roughly correspond to a combination of ecologic, genetic, and national boundaries, but ...

Species delimitation in sternaspid polychaetes is currently based on the morphology of a limited suite of characters, namely characters of the ventro-caudal shield—a unique feature of the family. Sternaspid species description has increased rapidly in recent years; however, the validity of the shie...
DEDICATION I would like to dedicate this work in memory of a very special uncle, Michael Venditto, who inspired my agricultural interests and to my mother and father, Fannie and Alex Adaskaveg, whose love was always felt and whose personal sacrifices, constant support, and faith have allowed ...
Molecular methods of species delineation are rapidly developing and widely considered as fast and efficient means to discover species and face the 'taxonomic impediment’ in times of biodiversity crisis. So far, however, this form of DNA taxonomy frequen
The notion of ‘microbes’ encompasses Bacteria (unicellular and multicellular) and Archaea, together with unicellular eukaryotes. In addition, microbiologists have traditionally included within their study field a number of eukaryotes named ‘fungi’ (customary meaning), e.g. Fungi (modern meaning), ...
A New Concept for the Taxonomy of the Family Dictyosteliaceae (Cellular Slime Molds)plant taxonomyIn addition to the typical whorls of branches, fruiting bodies of the genus Polysphondylium bear spores that are characterized by the presence of polar spore granules (PG). This spore character ...
Until recently, members of the monogeneric family Arenaviridae (arenaviruses) have been known to infect only muroid rodents and, in one case, possibly phyl
