The cicada genus Nipponosemia Kato is reviewed. Four species are illustrated, photographed and described, including three known species and one new species. A key to all species of this genusis presented, and information on the biology of Nipponosemia are provided. The systematic status of the tribe Cicadatrini and biogeography of Nipponosemia are discussed.

Competition takes place in many different spheres of life. This paper compares observations from economics, evolutionary biology, memetics and other fields of study in order to find similarities and differences between competition phenomena and their effects in different fields. A tentative framework is constructed for describing different competition phenomena and their effects. A systematic s...

This is a survey of the use of the bootstrap in the area of systematic and evolutionary biology. I present the current usage by biologists of the bootstrap as a tool both for making inferences and for evaluating robustness, and propose a framework for thinking about these problems in terms of mathematical statistics.

Gene Ontology facilitates biomedical knowledge representation and efficient information management. The systematic representation and hierarchical structure of Gene Ontology bring forth great potential to examine data and information across the broad spectrum of biology. This article briefly discusses GO annotation and three interesting areas in Gene Ontology-facilitated genome analysis.

Extrapulmonary infections caused by Legionella spp. other than Legionella pneumophila are rare. We report what is, to our knowledge, the first description of a prosthetic joint infection due to Legionella spp. Systematic testing of samples with suspected prosthetic infection by molecular biology techniques was essential. Legionella micdadei should be added to the list of microorganisms causing ...

Progress in molecular biology has opened the way to identifying genes involved in predisposition to multigene diseases. The two methods currently used for this purpose--analysis of candidate genes and systematic genomic screening--have given interesting but only very partial results. The problem is complicated by the large number of genes involved, their low penetrance, and linkage disequilibrium.

To better understand telomere biology in budding yeast, we have performed systematic suppressor/enhancer analyses on yeast strains containing a point mutation in the essential telomere capping gene CDC13 (cdc13-1) or containing a null mutation in the DNA damage response and telomere capping gene YKU70 (yku70Δ). We performed Quantitative Fitness Analysis (QFA) on thousands of yeast strains conta...

the systematics, morphology, distribution, biology, economic importance and conservation of the spiny eel ( mastacembelus mastacembelus ) of iran are described, the species is illustrated, and a bibliography on this fish is provided. the single species is distributed in southern iranian basins, including karkheh, karun, jarrahi and helleh river basins, mostly part of the tigris river and persia...
