Relationships of Adult and Larval Anatomy in the Supraspecific Classification of the Genus Culex in Southeast Asia (Diptera: Culicidae)
The supraspecific classification of the genus Culex has remained virtually unchanged since the monumental work of Edwards (1932), Some groups of this genus with limited regional distributions have more recently been critically examined in light of modern taxonomic concepts (for example: Colless (1965) re-evaluated the subgenus Lophoceraomyia in Malaya not only with consideration to adult and im...
متن کاملThe Symmetric Genus of the Mathieu Groups
The (symmetric) genus of a finite group may be defined as the smallest genus of those closed orientable surfaces on which G acts faithfully as a group of automorphisms. In this paper the genus of each of the five Mathieu groups Mn, M12, M22, M23 and M24 is determined, with the help of some computer calculations and a little-known theorem of Ree on permutations.
متن کاملPolymorphic chloroplast simple sequence repeat primers for systematic and population studies in the genus Hordeum
In this study we report the development of primers to amplify polymorphic chloroplast simple sequence repeats in the genus Hordeum, which includes cultivated barley (H. vulgare ssp. vulgare) and its wild progenitor H. vulgare ssp. spontaneum. Polymorphic products were amplified in a wide range of Hordeum spp. and intraspecific variation was detected in both cultivated and wild barley. A decreas...
متن کاملBarley whole exome capture: a tool for genomic research in the genus Hordeum and beyond
Advanced resources for genome-assisted research in barley (Hordeum vulgare) including a whole-genome shotgun assembly and an integrated physical map have recently become available. These have made possible studies that aim to assess genetic diversity or to isolate single genes by whole-genome resequencing and in silico variant detection. However such an approach remains expensive given the 5 Gb...
متن کاملOn the Genus of Symmetric Groups
A new method for determining genus of a group is described. It involves first getting a bound on the sizes of the generating set for which the corresponding Cayley graph could have smaller genus. The allowable generating sets are then examined by methods of computing average face sizes and by voltage graph techniques to find the best embeddings. This method is used to show that genus of the sym...
