PREMISE OF THE STUDY Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the semantic web. METHODS This paper provides background on what bio-ontol...

In as much as our paper (de Queiroz and Donoghue, 1988) was intended to be a contribution to, rather than a criticism of, phylogenetic systematics, it seems odd that Nelson (1989: 277) views our efforts as being "potentially destructive to the independence of cladistics". On closer inspection, however, Nelson's reaction is understandable as a manifestation of fundamental differences between wha...

James H. Oliver, Jr.’s Policy Forum “Crisis in biosystematics of arthropods” (20 May, p. 967) would have the scientific community do the right deed for the wrong reason. Systematics is not simply the identification of specimens, it is the reconstruction of evolutionary history; and it should be supported not just because it has practical applications (which it does) but because it is a fundamen...

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...

Classical plant morphology still provides the conceptual framework for most phytomorphological investigations and highly relevant concepts and data for other botanical disciplines such as plant morphogenesis, molecular genetics, ecology, systematics, evolutionary plant biology, etc. Typical classical morphology is categorical, i.e. the diversity of plant form is reduced to mutually exclusive mo...

With the development of open science and technological innovation, using sharing data molecular biology techniques in study taxonomy systematics have become a crucial component plants, which undoubtedly helps us discover more hidden outliers or deal with difficult taxa. In this paper, we take Dennstaedtia smithii as an example, based on database, virtual herbarium plant photo bank, to clarify t...
