Geminiviruses: Taxonomic Structure and Diversity in Genomic Organization
Recent Patents on Biotechnology, 2020Background: Geminiviridae is one of the best-characterized and hence, one of the largest plant-virus families with the highest economic importance. Its members characteristically have a circular ssDNA genome within the encapsidation of twinned quasi-icosaheadral virions (18-38 nm size-range).

Average Taxonomic Diversity and Distinctness
2008Taxonomic relatedness of the individuals or species in a sample is the key concept on which taxonomic diversity and distinctness measures of biodiversity are based. It is well known that in impacted assemblages of organisms the taxonomic spread of species is reduced, and in extreme cases they may be sibling species belonging to the same genus, or at ...

Taxonomic, Phylogenetic, and Ecological Diversity of Methanogenic Archaea
Anaerobe, 2000Methanogens are strict anaerobes which share a complex biochemistry for methane synthesis as part of their energy metabolism. The discovery of the unique biochemical and genetic properties of these organisms led to the concept of Archaebacteria at the end of the seventies and the proposal in 1990 for the domain Archaea.

Generation and Maintenance of Gradients in Taxonomic Diversity
Science, 1969Latitudinal gradients in diversity of organisms represent an equilibrium distribution for at least the last 270 × 10 6 years. Faunas endemic to tropical regions evolved significantly faster than extra-tropical faunas.

RNA isolation from taxonomically diverse photosynthetic protists
Limnology and Oceanography: Methods, 2018AbstractHigh quality RNA is a crucial requirement in a variety of analyses including next generation sequencing, microarray, and gene expression studies. A number of protocols for the extraction of ribonucleic acids from algae are currently in use, but different reagents interfere with buffer capacities and therefore lower the success of the isolations.

Taxonomic and Metabolic Microbial Diversity During Composting
1996A great variety and high numbers of aerobic thermophilic heterotrophic and/or autotrophic bacteria growing at temperatures between 60–80°C have been isolated from thermogenic (temperature 60–80°C) composts in several composting facilities in Switzerland. They include strains related to the genus Thermus (T. thermophilus. T. aquaticlls.

The unequal distribution of taxonomic diversity
1993Raikow (1986) feels that only the vagaries of taxonomy explain the higher number of species belonging to the passerine birds, compared with the non-passerine birds (but see the later comments by Fitzpatrick (1988), Vermeij (1988) and Kochmer and Wagner (1988) and Raikow’s (1988) reply). I cannot agree with Raikow’s views, as it is difficult to disprove

Determinants of diversity in higher taxonomic categories
Paleobiology, 1980It is often assumed that, if a few species are introduced into a relatively empty environment, the subsequent diversification will take the form of a logistic growth curve, rising to an equilibrium level of species richness. The diversifications of taxa in higher categories commonly resemble logistic curves, although there are no well-defined ...
