  Subspecies - Wikipedia, the free encyclopedia
In zoology, the scientific name of a subspecies is the binomen followed immediately by a subspecific name, e.g.
A subspecies indicated by the repetition of the specific name is known as the nominate subspecies.
Thus Motacilla alba alba is the nominate subspecies of White Wagtail, Motacilla alba.

 International Wolf Center Intermediate Wolf Information
A subspecies is a group of individuals within a species that share a geographic location and may have some unique physical characteristics.
Since the predominant color phase of this subspecies is a creamy white, which camouflages it in snowy surroundings, it is often called the white wolf.
This subspecies is now believed extinct in the wild, but may be represented in captivity or the reintroduced population in North Carolina.

 Subspecies and Classification   (Site not responding. Last check: 2007-10-22)
All subspecies are allopatric (either dichopatric [with non-contiguous ranges] or parapatric [with contiguous ranges], except for cases of circular overlap with sympatry); sympatry is conclusive evidence (except for cases of circular overlap) of allospecificity (separate specific status).
Dichopatric populations are regarded as subspecies if they fail to exhibit full differentiation (i.e., exhibit overlap in variation of their differentiae up to 25-30%), even in the absence of contact (overlap exceeding 25-30% does not qualify for taxonomic recognition of either dichopatric populations or of parapatric populations outside of their zones of intergradation).
In multivariate contexts, subspecies are definable by the suite of characters that explains the largest adequate percentage of the variance of the data-set, thus minimizing the “noise” produced by the variance of other characters.

 Wilson on Subspecies
The uncertainty of the limits of populations combined with the discordance of traits means that the subspecies is an arbitrary unit of classification.
The emphasis in research in anthropology and biology has passed from the description of subspecies to the analysis of the geography of separate traits and their respective contributions, singly or in combination, to survival and reproduction.
They suggest that subspecies be defined as individuals occupying a particular part of the range of the species, with genes and natural history distinct from those of other subspecies.

 SAVE THE TIGERS - Subspecies   (Site not responding. Last check: 2007-10-22)
Although scientists no longer classify tigers into subspecies, these names are commonly used to describe "races" of tigers from different regions that have slightly different physical characteristics.
There were 8 subspecies of Tiger at the beginning of the 20th century.
The smallest and darkest subspecies, Sumatran tigers are reddish and have closely spaced stripes.

 The Sibley Guide to Birds - Subspecies - loons_ducks
Two subspecies differ in size and subtly in plumage but are very difficult to distinguish, perhaps indistinguishable at sea.
Subspecies differ clinally in size and in extent of white in breeding plumes but no other significant differences, any division is arbitrary.
Rather arbitrarily divided here into six subspecies groups that differ in size, plumage, and voice; but all are connected by intermediate populations and identification can be difficult, even though the extremes seem like different species.

 Seasonality of Terrestrial Bird Subspecies Along the Oregon Coast
Webster's (1965) indicates that a subspecies is a subdivision of a species and that a subspecies designates a morphologically distinguishable and geographically isolated group whose members interbreed successfully with those of other subspecies of the same species where their ranges overlap.
Subspecies are diverse forms that can represent discrete, differing populations that have differing migration, nesting, or breeding areas, and, thus, subspecies may differ in seasonal status at a particular location.
The fourth problem in using subspecies is that the distribution of many subspecies may not be complete in the AOU (1957) because so little effort is now being given to the distribution of subspecies.

 Talk:Subspecies - Wikipedia, the free encyclopedia
"However, animals of the different subspecies of the same species might not interbreed even if geographical factor is removed." This statement seems to contradict the contents of the paragraph immediately preceding it.
That paragraph seemed to indicate that a requirement for a group of individual organisms being clubbed together in the same subspecific category was that they would in fact interbreed, if only the obstacles (physical ones were cited as example) to doing so were removed.
However, I'm wondering myself about the distinctions between subspecies, race (biology), morph (zoology), cultivar, and strain (biology).

In zoology only the subspecies is used, while in botany the variety, subvariety, and form are used as well.
In both cases, there is some uncertainty regarding correct classification, but the consensus view is that species rank is not justified in either.
The gene flow between northern and southern magpie populations is judged to be sufficiently restricted to justify terming them subspecies (not full species); but the seamless way that local Koala populations blend one into another shows that there is substantial gene flow between north and south.

 Identification of Canada and Cackling Geese
When reading published accounts of subspecies, it is important to bear in mind that in the confusing history of the taxonomy of Canada Geese, the subspecies have been grouped and named in various ways.
The subspecies defined below should be taken cautiously as merely one interpretation of the information at hand (which is patchy and incomplete, despite decades of study).
In all subspecies, there are subpopulations and gradual clinal changes so that it is difficult to define the characteristics of that subspecies without looking at a broad geographic sample.

Subspecies is the first in a four part movie series involving Radu, the baddest vampire in town.
Our first introduction to Radu is when he kills his father in order to take possession of the Bloodstone, a vampire family heirloom that allows them to survive a long time without a fresh "meal", and gives them power by drinking from it.
Thus, "Subspecies" is a must-see for real vampire lovers due to its originality and inherently unique qualities.

 Old World Aviaries: Grey subspecies
One also will know that the first name that repeats the species is the nominate subspecies of that species....in other words, it is the first subspecies that was discovered.
Some of the guidelines for defining a subspecies are bone structure, size, shape, color difference, habitat needs, and physical separation, such as mountain ranges, canyons, deserts or large expanses of unpopulated areas.
They are simply variations of the same subspecies based on the areas in which they live.

Recognition of the southern subspecies is supported by Dr Don Sands of CSIRO Entomology who has relevant expertise and indicates that the subspecies is yet to be formally described.
It is geographically separated and morphologically distinct from the southern subspecies (Sands 1999).
Little is known of the subspecies' distribution and life history and very little is known about the distribution and life history of its food plant in NSW, which appears to be relatively rare.

 Canada Goose subspecies
In the early 1950s, it was split up into 12 subspecies, of which two were believed to be extinct though one, the Giant Canada Goose, was later found still to exist.
At the time, it was thought that all the subspecies were separated geographically, at least on the breeding grounds if not entirely in winter.
Even as early as the 1970s, one researcher, working by Hudson Bay where two subspecies breed, was talking about a 'complex' of mixed subspecies as he was no longer able to identify many of the pairs he was studying.

 GENES REVEAL NEW SUBSPECIES OF TIGER   (Site not responding. Last check: 2007-10-22)
Biologists traditionally have recognized eight subspecies of tiger, including three that were wiped out by hunting and habitat destruction in the 20th century.
The new study splits that subspecies into two: the Malayan tiger, found on the Malaysian Peninsula, and the northern Indochinese tiger, found in areas ranging from Myanmar to extreme southwest China.
Biologists traditionally use physical characteristics such as skull size, coloration and stripe pattern to distinguish one tiger subspecies from another, but the Malayan and northern Indochinese subspecies are nearly identical in appearance, Sunquist said.

 EPA: Bacillus thuringiensis subspecies israelensis strain EG2215 (006476) Fact Sheet
Bacillus thuringiensis subspecies israelensis is formulated for use on mosquito larvae in aquatic habitats.
Because the health risk is expected to be negligible for oral, dermal, and inhalation exposure routes, as previously indicated, aggregate exposure by these routes, from naturally-occurring populations in the soil and from the use of pesticidal products, should not pose a threat to human health.
Exposure assessments on this type of microbial pesticide are not performed unless significant human health or ecological effects issues arise in the Tier I studies (40 CFR 158.690 (c)).
