Ultisols, commonly known as red clay soils, are one of twelve soil orders in the United States Department of Agriculture soil taxonomy.

Current taxonomy classifies the Australian dingo, together with its closest relatives outside of Australia, as Canis lupus dingo, a subspecies of grey wolf separate from the familiar common dog, Canis lupus familiaris, while still united with familiaris as an intrataxonomic clade called "< nowiki > dog </ nowiki >".

This taxonomy assumed that domestic dogs are a distinct species from the grey wolf, with the dingo classified as a subspecies of domestic dog.

This complicates taxonomy and Amaranthus has generally been considered among systematists as a " difficult " genus.

The taxonomy of the genus has been controversial.

Such an order has been recognized by a few systems of plant taxonomy, with a various placement.

Some official bodies have adopted the proposed Sibley-Ahlquist taxonomy almost entirely, however a more common approach worldwide has been to retain the traditional groupings, and modify rather than replace them in the light of new evidence as it comes to hand.

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.

For example, the skills, rules, and knowledge taxonomy of human behavior has been used by designers to develop systems that are compatible with multiple " ways of knowing ": abstract analytic reasoning, experience-based ' gut feelings ', and ' craft ' sensorimotor skills.

Despite the numerous oppositions, Haeckel has influenced many disciplines in science in his drive to integrate such disciplines of taxonomy and embryology into the Darwinian framework and to investigate phylogenetic reconstruction through his Biogenetic Law.

In referring to taxonomy of the Animalia, " invertebrata " is a term of convenience, not a taxon ; it has very little circumscriptional significance except arguably within the Chordata.

The taxonomy of the jackals has evolved with scientific understanding about how they are related on the canid family tree.

Heller's names and the designations he gave to various jackal species and subspecies live on in current taxonomy, although the genus has been changed from Thos to Canis.

His taxonomy of minerals has dropped long since from use.

The taxonomy of the genus Mimosa has had a tortuous history, having gone through periods of splitting and lumping, ultimately accumulating over 3, 000 names, many of which have either been synonymized under other species or transferred to other genera.

Cosmologist Max Tegmark has provided a taxonomy of universes beyond the familiar observable universe.

The taxonomy has undergone changes and is likely to change further, as a number of genetic studies are bringing forth new information.

This method has become quite rare in modern times, having been largely superseded by cladistic analyses, as numerical taxonomy is sensitive to being misled by plesiomorphic traits.

Rather than propose a single definition for ubiquitous computing and for these related terms, a taxonomy of properties for ubiquitous computing has been proposed, from which different kinds or flavors of ubiquitous systems and applications can be described.

The taxonomy of the genus Brettanomyces has been debated since its early discovery and has seen many re-classifications over the years.

In literature, genre has been known as an intangible taxonomy.

The Sibley-Ahlquist taxonomy, which has been widely accepted in America, lumps all the Charadriiformes together with other seabirds and birds of prey into a greatly enlarged order Ciconiiformes.

DNA evidence has confirmed common ancestry for all Procellariiformes, however, the taxonomy within the order is complex and fluctuating.

The taxonomy of this group of plants within the Rosaceae has recently been unclear.

The taxonomy of this subfamily has changed several times in the last century as more detailed studies have been carried out.

Species ( often dubious ones now known to be based on sexual variation or juvenile characters ) have been reclassified a number of times, and several sub-genera have in the 1970s been erected by Halsey Wilkinson Miller to hold them in various combinations, further confusing the taxonomy ( subgenera include Longicepia, Occidentalia, and Geosternbergia ).

To date the suggestions proposed have not been broadly accepted because of doubts over the suitability of a single gene to determine the taxonomy of the clade.

The following systematic list ( gender taxonomy ) illustrates the kinds of diversity that have been studied and reported in medical literature.

In phylogenetic taxonomy, the genus has been used as a reference point in the definition of Dinosauria ; Dinosaurs have been designated as all descendants of the most recent common ancestor of Triceratops and Neornithes ( i. e. modern birds ).

Some official bodies have adopted the proposed Sibley-Ahlquist taxonomy almost entirely ; however, a more common approach worldwide has been to retain the traditional groupings, and modify rather than replace them in the light of new evidence as it comes to hand.

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 gradually to resolve themselves as more evidence becomes available.

It has been a point of contention ever since which is correct ; the latter is more correctly formed, but the convention in taxonomy is that the first name given stands, unless it is clearly a typographical error.

The taxonomy of the stilts is particularly debated, with the genus Himantopus considered to have two to six species.

The taxonomy of ringed seal has been much debated and revised in the literature.

The taxonomy of the towhees has been debated in recent decades, and formerly this bird and the Eastern Towhee were considered a single species, the Rufous-sided Towhee.

The taxonomy of the Royal Tern has been debated, whether the correct scientific name was Thalasseus maximus or Sterna maxima.

The taxonomy of the group of towhees to which this species belongs is debated.

The taxonomy of this species has been debated.

Beyond that, considerable revision in the taxonomy of the flies has taken place since the introduction of modern cladistic techniques, and much remains uncertain.

Other research has cast doubt on the taxonomy of the Pica magpies, since it appears that P. hudsonia and P. nuttalli may not be different species, whereas the Korean race of P. pica is genetically very distinct from the other Eurasian ( as well as the North American ) forms.

However the distinction between these two common names does not map completely into current taxonomy, since jackrabbits are members of Lepus, and members of the genera Pronolagus and Caprolagus are sometimes called hares.

The taxonomy of Mystacocarida is extremely conservative, since all mystacocarids look superficially alike.

Carl Linnaeus published a basic taxonomy for the natural world in 1735 ( variations of which have been in use ever since ), and in the 1750s introduced scientific names for all his species.

* In viticulture nomenclature, what is referred to as " grape varieties " are in reality cultivars according to usage in the International Code of Nomenclature for Cultivated Plants or " plant varieties " in the legal sense rather than botanical taxonomy varieties, since they are propagated by cuttings and have properties that are not stable under sexual reproduction ( seed plants ).

It has been a point of contention ever since which is correct ; the latter is more correctly formed, but the convention in taxonomy is that the first name given stands, unless it is clearly a typographical error.

The classification and taxonomy of Rhamphorhynchus, like many pterosaur species known since the Victorian era, is complex, with a long history of reclassification under a variety of names, often for the same specimens.

In traditional taxonomy, Therapsida was separated from Pelycosauria in its own biological order, and mammals were separated from both as their own class, though such usage has not been continued by a majority of scientists since the 1990s.

Sphagnum taxonomy has been very contentious since the early 1900s ; most species require microscopic dissection to be identified.

As an example, amphibians are monophyletic under evolutionary taxonomy, since it has arisen from fishes only once.

All families of Architectibranchia were already within the Lower Heterobranchia in the taxonomy of Bouchet & Rocroi, except for the Notodiaphanidae, which has been placed in the Lower Heterobranchia since 2010, in order that the Architectibranchia can be considered to be monophyletic.

This makes it difficult to conduct cross-linguistic investigations of clefts since these elements do not exist in other languages, which has led to a proposal for a revision of existing cleft taxonomy ( see Calude 2009 ).

As most dinosaur paleontologists have advocated a shift away from traditional, ranked Linnaean taxonomy in favor of rankless phylogentic systems, few ranked taxonomies of dinosaurs have been published since the 1980s.

Although the taxonomy of the genus has not been reviewed since 1955, the following species are recognised:

The taxonomy of Verbascum has not undergone any significant revision since Svanve Mürbeck's monographies in the 30s, with the exception of the work of Arthur Huber-Morath, who used informal group in organizing the genus for the floras of Iran and Turkey to account for many intermediate species.
