In biology, an identification key, taxonomic key, or frequently just key, is a printed or computer-aided device that aids in the identification of biological organisms. Historically, the most common type of identification key is the dichotomous key , a type of single-access key which offers a fixed sequence of identification steps, each with ...
Identifying moths. Identification in biology is the process of assigning a pre-existing taxon name to an individual organism.Identification of organisms to individual scientific names (or codes) may be based on individualistic natural body features, [1] experimentally created individual markers (e.g., color dot patterns), or natural individualistic molecular markers (similar to those used in ...
In biology, determination is the process of matching a specimen or sample of an organism to a known taxon, for example identifying a plant as belonging to a particular species. Expert taxonomists may perform this task, but structures created by taxonomists are sometimes used by non-specialists.
Systematic biology (hereafter called simply systematics) is the field that (a) provides scientific names for organisms, (b) describes them, (c) preserves collections of them, (d) provides classifications for the organisms, keys for their identification, and data on their distributions, (e) investigates their evolutionary histories, and (f ...
DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
HENDERSONVILLE - For the second year in a row, a student from Henderson County Public Schools has won Optimum and TelevisUnivision's Hispanic Heritage Month essay contest, which is an annual ...
In biology, phylogenetics (/ ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/) [1] [2] [3] is the study of the evolutionary history of life using genetics, which is known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences ...
One important and unique event in plant morphology of the 21st century was the publication of Kaplan's Principles of Plant Morphology by Donald R. Kaplan, edited by Chelsea D. Specht (2020). [36] It is a well illustrated volume of 1305 pages in a very large format that presents a wealth of morphological data.
