Ecological Niche
In ecology , a NICHE (CanE , UK : /ˈniːʃ/ or US : /ˈnɪtʃ/ ) is a term with a variety of meanings related to the fit of a species living under specific environmental conditions. The ecological niche describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators , parasites and pathogens are scarce) and how it in turn alters those same factors (for example, limiting access to resources by other organisms, acting as a food source for predators and a consumer of prey). "The type and number of variables comprising the dimensions of an environmental niche vary from one species to another the relative importance of particular environmental variables for a species may vary according to the geographic and biotic contexts". The notion of ecological niche is central to ecological biogeography , which focuses on spatial patterns of ecological communities

Terrestrial Ecoregion
An ECOREGION (ECOLOGICAL REGION) is an ecologically and geographically defined area that is smaller than a bioregion , which in turn is smaller than an ecozone . All three of these are either less or greater than an ecosystem . Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species . The biodiversity of flora , fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa

W.Zimm.
WALTER MAX ZIMMERMANN (May 9, 1892 – June 30, 1980) was a German botanist and systematist . Zimmernann’s notions of classifying life objectively based on phylogenetic methods and on evolutionarily important characters were foundational for modern phylogenetics. Though they were later implemented by Willi Hennig in his fundamental work on phylogenetic systematics, Zimmermann's contributions to this field have largely been overlooked. Zimmermann also made several significant developments in the field of plant systematics such as the discovery of the telome theory . The standard botanical author abbreviation W.ZIMM. is applied to species he described.

Neogene
The NEOGENE ( /ˈniːəˌdʒiːn/ ) is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago (Mya ) to the beginning of the present Quaternary Period 2.58 Mya. The Neogene

and the later Pliocene . Some geologists assert that the Neogene

ARTHUR JOHN CRONQUIST (March 19, 1919 – March 22, 1992) was a United States
United States
biologist, botanist and a specialist on Compositae . He is considered one of the most influential botanists of the 20th century, largely due to his formulation of the Cronquist system

. Two plant genera in the aster family have been named in his honor. These are Cronquistia, a possible synonym of Carphochaete , and Cronquistianthus , which is sometimes included as a group within Eupatorium . The former was applied by R.M. King and the latter by him and Harold E. Robinson

was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich

Synonym (taxonomy)
In scientific nomenclature , a SYNONYM is a scientific name that applies to a taxon that (now) goes by a different scientific name, although the term is used somewhat differently in the zoological code of nomenclature. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called Pinus abies. This name is no longer in use: it is now a synonym of the current scientific name which is Picea abies
Picea abies
. Unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it is a synonym. In taxonomy, synonyms are not equals, but have a different status. For any taxon with a particular circumscription , position, and rank, only one scientific name is considered to be the correct one at any given time (this correct name is to be determined by applying the relevant code of nomenclature )

Character (biology)
A PHENOTYPIC TRAIT, or simply TRAIT, is a distinct variant of a phenotypic characteristic of an organism ; it may be either inherited or determined environmentally, but typically occurs as a combination of the two. For example, eye color is a CHARACTER of an organism, while blue, brown and hazel are traits.

An example of a phenotypic trait is hair color; underlying genes, which make up the genotype , "control" the hair color, but the actual hair color, the part we see, is the phenotype

Period 66 million years ago (Mya ) to the beginning of the Neogene Period 23.03 Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon.

Taxonomy (biology)
TAXONOMY (from Ancient Greek τάξις (taxis ), meaning 'arrangement', and -νομία (-nomia), meaning 'method ') is the science of defining and naming groups of biological organisms on the basis of shared characteristics. Organisms are grouped together into taxa (singular: taxon) and these groups are given a taxonomic rank ; groups of a given rank can be aggregated to form a super-group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain , kingdom , phylum (division is sometimes used in botany in place of phylum), class , order , family , genus and species . The Swedish botanist Carl Linnaeus
Carl Linnaeus
is regarded as the father of taxonomy, as he developed a system known as Linnaean taxonomy

Megaannum
A YEAR is the orbital period of the Earth
Earth
moving in its orbit around the Sun
Sun
. Due to the Earth's axial tilt , the course of a year sees the passing of the seasons , marked by changes in weather , the hours of daylight , and, consequently, vegetation and soil fertility . In temperate and subpolar regions around the globe, four seasons are generally recognized: spring , summer , autumn and winter . In tropical and subtropical regions several geographical sectors do not present defined seasons; but in the seasonal tropics , the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period as counted in a given calendar . The Gregorian, or modern, calendar , presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars ; see below
