In general schemes, this idea has been applied by several classificationists in identifying a series of integrative levels, each originated from the previous ones, and using them as the main classes. In special schemes, common origin is a key principle in many domains: examples are given from ...
The grouping of Galloanserae with Palaeognathae was later replaced (Sibley and Ahlquist, 1990) by the now well corroborated topology that places Palaeognathae sister to Neognathae, which consists of two major clades, Galloanserae and Neoaves. Unfortunately, in their revised classification, ...
505). The metagenetic life cycle in Medusozoa was described thereafter7, with consequences for the taxonomic arrangement due to a dual classification system, one for polyps and another for medusae. Subsequently, Thecaphora was proposed by Hincks (1868)8 as “Hydroida furnished with thecae” (...
Evolution and functional classification of vertebrate gene deserts Large tracts of the human genome, known as gene deserts, are devoid of protein-coding genes. Dichotomy in their level of conservation with chicken separate... Ovcharenko,I. - 《Genome Research》 被引量: 859发表: 2005年 ...
Special attention has been given to the stylet guiding system in all forms considered. An attempt is made to assess the interrelationships of the different genera, and the resulting cladogram is used as a basis for a new classification of the family. Biogeography supports the phylogenetic scheme...
Although the human bladder is reported to harbor unique microbiota, our understanding of how these microbial communities interact with their human hosts is limited, mostly owing to the lack of isolates to test mechanistic hypotheses. Niche-specific bacte
Towards a natural classification of Ophiobolus and ophiobolus-like taxa;introducing three novel genera Ophiobolopsis, Paraophiobolus and Pseudoophiobolus i... Ophiobolus is a large genus of Phaeosphaeriaceae comprising more than 350 possible species,most of which are saprobes on herbaceous plants ...
Nomenclatural histories of all taxa are given; taxon distributions are plotted; and all materials examined are cited. Character polarities and distributions as well as the linear classification are tabulated; cladograms and phylograms are figured. Three major lineages involve Rhoenanthus, representing ...
While this can be done with some success, there remains significant room for improving the classification accuracy by adaptively updating the models used for detection. The heuristics presented here rely on the fact that we actually possess genomic fragments from the unknown genome in the mixture. ...
In a strictly phylogenetic classification all taxa must be monophyletic and all sister groups given equal rank. If these principles are followed, the classification will reflect nature's own hierarchy and its groups will be directly useful in all branches of causal biology. The effects of ...
