Systematics uses taxonomy as a primary tool in understanding organisms, as nothing about an organism's relationships with other living things can be understood without it first being properly studied and described in sufficient detail to identify and classify it correctly.

Systematics is fundamental to biology because it is the foundation for all studies of organisms, by showing how any organism relates to other living things ( ancestor-descendant relationships ).

Two game companies, Antenna Research and Cortical Systematics, compete against each other.

These and other discoveries led Ernst Mayr to first formulate a theory on ring species in his 1942 study Systematics and the Origin of Species.

Comparative biology encompasses Evolutionary Biology, Systematics, Neontology, Paleontology, Ethology, Anthropology, and Biogeography as well as historical approaches to Developmental biology, Genomics, Physiology, Ecology and many other areas of the biological sciences.

The Laboratory Plant Morphology, Systematics and Ecology was able to conclusively demonstrate that certain materials complement each other in a synergetic manner and provide soil conditioning benefits whose collective effect is better than the effect of their individual parts.

In his book Systematics and the Origin of Species ( 1942 ) he wrote that a species is not just a group of morphologically similar individuals, but a group that can breed only among themselves, excluding all others.

Taxonomy is that part of Systematics concerned with topics ( a ) to ( d ) above.

Systematics is also of major importance in understanding conservation issues because it attempts to explain the Earth's biodiversity and could be used to assist in allocating limited means to preserve and protect endangered species, by looking at, for example, the genetic diversity among various taxa of plants or animals and deciding how much of that to preserve.

When the pair return to the game store, Hugo Carlaw ( Callum Keith Rennie ) informs them that Nourish is actually a double agent for Cortical Systematics, and the waiter whom Pikul shot was the actual contact.

Before Carlaw can kill Allegra, he is shot in the back by Vinokur, who is a double agent for Cortical Systematics.

An example of studies of this type is Richard B. Selander's Bionomics, Systematics and Phylogeny of Lytta, a Genus of Blister Beetles ( Coleoptera, Meloidae ), Illinois Biological Monographs: number 28, 1960.

Overlap with ecology is also prominent in the review journals Trends in Ecology and Evolution and Annual Review of Ecology, Evolution, and Systematics.

The journal is divided into the following sections: Morphology, Systematics, Evolution ; Sampling, Distribution, Dispersal ; Development, Life History ; Population and Community Ecology ; Behavior, Chemical Ecology ; Population Biology / Genetics ; Molecular Biology / Genomics ; Neurobiology, Physiology, Biochemistry ; Vector Control, Pest Management, Resistance, Repellents ; Arthropod / Host Interaction, immunity ; Vector / Pathogen / Host Interaction, Transmission ; Vector Borne Diseases, Surveillance, Prevention ; Direct Injury, Myiasis, Forensics ; Modeling / GIS, Risk Assessment, Economic Impact.

* German entomologist Willi Hennig's Phylogenetic Systematics is published in English, advancing the study of cladistics.

Systematics of shads is complex.

Some authorities retain Lafresnaye's position as a subspecies of the Buff-throated Woodcreeper, but the resulting group is polyphyletic ( see Systematics and evolution ).

Pseudorhipsalis is sometimes included in Disocactus, although kept separate by the International Cactaceae Systematics Group.

Researchers at the University of California, Berkeley ( especially Daniel McFadden, who won a " Nobel " Prize in Economics for his efforts ) and the Massachusetts Institute of Technology ( Moshe Ben-Akiva ) ( and in MIT associated consulting firms, especially Cambridge Systematics ) developed what has become known as choice models, direct demand models ( DDM ), Random Utility Models ( RUM ) or, in its most used form, the multinomial logit model ( MNL ).

Since the mid-1990s, the system produced by the International Cactaceae Systematics Group ( ICSG ) of the International Organization for Succulent Plant Study has been used as the basis of many published classifications.

** Systematics: taxon — taxonomy — scientific classification — phylogeny — evolutionary tree — cladistics — synapomorphy — homology — molecular clock

During his time at the museum he produced numerous publications on bird taxonomy, and in 1942 his first book, Systematics and the Origin of Species, which completed the evolutionary synthesis started by Darwin.

Systematics changed from being based on phenotype to the underlying genotype.

The belly and undertail are either blackish-grey ( western subspecies ; see Systematics, below ) or orange-red ( eastern subspecies ); the wings are blackish-grey with pale fringes on the secondaries forming a whitish panel ( western subspecies ) or all blackish ( eastern subspecies ).

The journal was designed to spread the ideas of the discipline of Systematics, a practical analytical method based on his own researches into the laws governing processes in the natural world.

( 1997 ), interpreted by George Sangster in 1997, indicated that the olivaceous and Booted / Sykes's warbler grouping ( the subgenus Iduna ) are more closely related to Acrocephalus species than they are to Icterine and Melodious Warblers and as a result the Dutch Committee on Avian Systematics ( CSNA ) has moved these four species into Acrocephalus.

Dye worked on several committees connected with bacterial taxonomy, most notably the International Committee on the Systematics of Bacteria, participating in the complete revision of bacterial names contained in the Approved Lists of Names of Bacteria, and the Committee on Taxonomy of Plant Pathogenic Bacteria of the International Society for Plant Pathology, which developed the International Standards for Naming Pathovars.

For classification and nomenclature of species there are special rules, which are maintained by the International Committee on Systematics of Prokaryotes ( ICSP ) Subcommittee on the Taxonomy of Mollicutes ( formerly the International Committee on Systematic Bacteriology ( ICSB ) Subcommittee on taxonomy of Mycoplasmatales ).
