Genera via Deformation Theory and Supersymmetric Mechanics
We study naturally occurring genera (i.e. cobordism invariants) from the deformation theory in- spired by supersymmetric quantum mechanics. First, we construct a canonical deformation quantization for symplectic supermanifolds. This gives a novel proof of the super-analogue of Fedosov quantization. …

Orbifold genera, product formulas and power operations
… formulas for these higher chromatic orbifold genera in the same way that the product formula for the topological Todd genus is proved. More precisely, we show that any genus induced by an H[omega]-map into one of the Morava-Lubin-Tate cohomology theories Eh has such a product formula and that …

Chromosome studies in the genera Lycopersicon and Solanum
This thesis comprises two Parts and concerns the cytology of Lycopersicon and Solanum. Part I was a study of pachytene in Lycopersicon and began as an attempt to assess the usefulness of this stage as a source of information to aid classification. The principal findings of this thesis were as …

A Phylogenetic Study of Cymopterus and Related Genera (Apiaceae)
… and its relationship to other perennial genera of Apiaceae subfamily Apioideae endemic to western North America (north of Mexico). Cladistic analyses of nuclear (rDNA internal transcribed spacer) and chloroplast ( rps16 intron and trnF-trnL- trnT) DNA sequences were carried out for 129 …

A taxonomic monograph of Lampranthus and allied genera (Mesembryanthemaceae)
For the first time since the genera were described, a taxonomic monograph of Lampranthus and its immediate allies was undertaken. A numerical study of 97 characters (132 character strings) of each of some 270 items was undertaken, using Hall's BOLAID package of numerical aids. The genus Lampranthus …

Taxonomic studies in the genus Acrostemon Kl. and related genera
… of Acrostem912 revealed that the two monotypic genera, Hexastemon Kl. and Arachnocalyx Compton, could not be upheld as separate genera. They were therefore reduced under Acrostemon. Studies of variation and intergradation in the distinguishing characters between Acrostemon and the genera, …

Systematics of the spider genera Mallos and Mexitilia (Arameae: Dictynidae)
This systematic study recognizes 15 species of the genus Mallos Pickard-Cambridge and three species of the genus Mexitilia Lehtinen. Three species of Mallos and one species of Mexitilia are newly described. Two species are placed in synonymy and two species are transferred to Mallos. The males of …

Microbial Diversity in the Human Mouth: Dominant Genera and their Interactions.
… mouth rinse samples identified many bacterial genera from six phyla. These genera included Streptococcus, Gemella, Veillonella, Eubacterium, Porphyromonas, Neisseria, Rothia and Prevotella. The three prevalent genera, as defined by the number of times observed from mouth rinse samples, were …

Comparison of Laboratory Rhythms in Several Species and Genera of Ants
… have been made at the genus level. Four genera (Pogonomyrmex, Veromessor, Formica, Myrmecocystus) of ants were compared, two of them represented by two species each. Under controlled temperatures, in alternating light and dark, there was more difference in phase of rhythm among than …
