Variety (botany)

In botanical nomenclature, variety (abbreviated var.; in Latin: varietas) is a taxonomic rank below that of species and subspecies but above that of form. As such, it gets a three-part infraspecific name.

Example

The pincushion cactus, Escobaria vivipara (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about 2,600 metres (8,500 ft). Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety Escobaria vivipara var. arizonica is from Arizona, while Escobaria vivipara var. neo-mexicana is from New Mexico.

Definitions

The term is defined in different ways by different authors. A variety will have an appearance distinct from other varieties, but will hybridize freely with those other varieties (if brought into contact). Usually varieties will be geographically separate from each other.

Other nomenclature uses

Biology

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy. Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it that govern all study and research, consolidating it into single, coherent fields. In general, biology recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energy and by regulating their internal environment to maintain a stable and vital condition.

Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions among biological molecules; botany studies the biology of plants; cellular biology examines the basic building-block of all life, the cell; physiology examines the physical and chemical functions of tissues, organs, and organ systems of an organism; evolutionary biology examines the processes that produced the diversity of life; and ecology examines how organisms interact in their environment.

Biology (journal)

Biology is a quarterly, peer-reviewed, open access, scientific journal covering research on all aspects of biology. It was established in 2012 and is published by MDPI. The editor-in-chief is Chris O'Callaghan (University of Oxford). The journal publishes reviews, research papers, and communications.

Subject Areas

This journal covers all topics related to biology. More detail about the journal and its scope is available in the first editorial. Research fields of interest include, but are not limited to:

Biology 101

"Biology 101" is the first episode of the third season of Community. The episode originally aired on September 22, 2011 on NBC. The episode picks up where the second season left off, with Pierce out of the group. The study group resumes class at Greendale and decides to enroll in Biology.

The episode was written by Neil Goldman and Garrett Donovan and directed by Anthony Russo.

Plot

The study group decides to take a Biology class together, but Pierce soon faces problems when only six seats are available in the class. Jeff quickly makes enemies with their professor (Michael K. Williams) and is removed from the class, leaving an open slot for Pierce in both the class and their study group. Jeff's plans to reveal Pierce's relationship to the new professor backfires. Dean Pelton unwisely stokes a rivalry with Vice Dean Laybourne (John Goodman), the dean of the school's lucrative Air Conditioning Repair Annex. Abed becomes despondent when Cougar Town goes into hiatus and the group tries to cheer him up by introducing him to Cougarton Abbey, a British show that Cougar Town was based on. Unfortunately, that show was cancelled after six episodes, ending with the main characters committing mass suicide.

Glossary of numismatics

This article is a collection of Numismatic and coin collecting terms with concise explanation for the beginner or professional.

Numismatics (ancient Greek: νομισματική) is the scientific study of money and its history in all its varied forms. While numismatists are often characterized as studying coins, the discipline also includes the study of banknotes, stock certificates, medals, medallions, and tokens (also referred to as Exonumia).
