The actual number of species in each group depends on the taxonomic classification followed.

With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a paraphyletic group without unique defining features apart from shared primitive characteristics.

The members of this group have a complex taxonomic history, having been assigned to widely differing families in different classification systems.

Under the Cronquist system of taxonomic classification of flowering plants Asteraceae was the only family in the group, but newer systems ( such as APG II and APG III ) have expanded it to eleven.

Although this classification was widely accepted, further infrageneric classification was ( and still is ) needed to differentiate this widely diverse group.

Scientific classification in botany is a method by which botanists group and categorize organisms by biological type, such as genus or species.

Cape Verde is a group of arid Atlantic islands which are home to a number of birds and reptiles and constitute a unique ecoregion in the World Wildlife Fund classification.

In mathematics, the classification of the finite simple groups is a theorem stating that every finite simple group belongs to one of four categories described below.

Thanks to the classification theorem, such questions can sometimes be answered by checking each family of simple groups and each sporadic group.

Their classification is divided into the small and large rank cases, where the rank is the largest rank of an odd abelian subgroup normalizing a nontrivial 2-subgroup, which is often ( but not always ) the same as the rank of a Cartan subalgebra when the group is a group of Lie type in characteristic 2.

The main part of the classification produces a characterization of each simple group.

A more recent classification based on mutual intelligibility separates modern spoken Danish, Norwegian and Swedish into a Mainland Scandinavian group while Icelandic and Faroese are placed in a separate category labelled Insular Scandinavian.

Because of all these, the mere classification of Sireniki Eskimo language is not settled yet: Sireniki language is sometimes regarded as a third branch of Eskimo ( at least, its possibility is mentioned ), but sometimes it is regarded rather as a group belonging to the Yupik branch.

It is included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system.

Historically, the concept of fundamental group first emerged in the theory of Riemann surfaces, in the work of Bernhard Riemann, Henri Poincaré and Felix Klein, where it describes the monodromy properties of complex functions, as well as providing a complete topological classification of closed surfaces.

Yet, the name of the Suebi — which designated a larger group of tribes and was used by Caesar somewhat indescriminantly when describing Germanic tribes east of the Rhine — was possibly a Germanic word which was used to describe a broad classification of Germanic speakers (* swē-ba-" authentic ").

* Linear algebraic groups ( or more generally affine group schemes ) — These are the analogues of Lie groups, but over more general fields than just R or C. Although linear algebraic groups have a classification that is very similar to that of Lie groups, and give rise to the same families of Lie algebras, their representations are rather different ( and much less well understood ).

In analogy to the linguistic classification, Kashubians are considered either an ethnic or a linguistic group.

" The classification of the Kadugli language group ".

Bibliographic classification systems group entities together that are relevant to the same subject, typically arranged in a hierarchical tree structure ( like classification systems used in biology ).

This study recovered a group of rosids unlike any group found in any previous system of plant classification.

We also have an ' engineering section head -- research engineer ' classification which has salary possibilities equivalent to that of a research engineer.

but he has not worked out by lexicostatistics one comprehensively complete classification of even a single family other than Salish.

The order has only recently been recognized in classification systems.

The field of classifying Apicomplexa is in flux and classification has changed throughout the years since it was formally named in 1970.

Afyonkarahisar has a mediterranean climate ( Köppen climate classification Csa ) and semi-arid climate ( Köppen climate classification BSk ), with cold and snowy winters and hot and dry summers.

The stellar classification of this star is B2. 5, with numerous spectral lines suggesting it has been polluted by matter ejected by Antares.

Berlin has a humid continental climate according to the Köppen climate classification system.

Bursa has a borderline Mediterranean / humid subtropical climate ( Köppen climate classification: Csa / Cfa ).

The five-kingdom system has largely been superseded by modern alternative classification systems.

The endolithic biome, consisting entirely of microscopic life in rock pores and cracks, kilometers beneath the surface, has only recently been discovered, and does not fit well into most classification schemes.

Berkeley has a cool summer Mediterranean climate ( Köppen climate classification Csb ), with dry summers and wet winters.

It has also proved difficult to produce a detailed classification within the living chordates.

According to one principle of classification, an emergent coastline is a coastline which has experienced a fall in sea level, because of either a global sea level change, or local uplift.

The most commonly used form of the Köppen classification has five primary types labeled A through E. These primary types are A, tropical ; B, dry ; C, mild mid-latitude ; D, cold mid-latitude ; and E, polar.

Bird taxonomy has been in a state of flux for some years, and it is reasonable to expect that the large differences between different classification schemes will continue to gradually resolve themselves as more evidence becomes available.

The Council of Europe has called the SVP " extreme right ", although some scholars dispute this classification.

Over the years, the classification of the genera and species has evolved.

Casablanca has a very mild Mediterranean climate ( Köppen climate classification Csa ).

The classification theorem has applications in many branches of mathematics, as questions about the structure of finite groups ( and their action on other mathematical objects ) can sometimes be reduced to questions about finite simple groups.

The first classification has only seven top level classes, and only eight classes in all.

The College has an additional classification of social / residential organizations known as undergraduate societies.

If anything, the research has shown the situation is even more complex than initially imagined, and we believe not enough is known to structure the classification of psychiatric disorders according to etiology.

Despite caveats in the introduction to the DSM, it has long been argued that its system of classification makes unjustified categorical distinctions between disorders, and uses arbitrary cut-offs between normal and abnormal.
