Anas is a genus of dabbling ducks. It includes mallards, wigeons, teals, pintails and shovelers in a number of subgenera. Some authorities prefer to elevate the subgenera to genus rank (Carboneras 1992). Indeed, as the moa-nalos are very close to this clade and may have evolved later than some of these lineages, it is rather the absence of a thorough review than lack of necessity that this genus is rather over-lumped.

70.110.15.106 21:16, 15 November 2007 (UTC)==Systematics== The phylogeny of this genus is one of the most confounded ones of all living birds. Research is hampered by the fact the radiation of the two major groups of Anas — the teals and mallard groups — took place in a very short time and fairly recently, roughly in the mid-late Pleistocene. Furthermore, hybridization probably has long played a major role in Anas evolution, with within-subgenus hybrids regularly and between-subgenus hybrids not infrequently being fully fertile (Carboneras 1992; see also Mariana Mallard). The relationships between species are much obscured by this fact, and mtDNA sequence data is of dubious value in resolving their relationships (e.g. Kulikova et al. 2005); on the other hand, nuclear DNA sequences evolve too slowly to resolve the phylogeny of the subgenus Anas for example. In biology, phylogenetics (Greek: phylon = tribe, race and genetikos = relative to birth, from genesis = birth) is the study of evolutionary relatedness among various groups of organisms (e. ... Tasman Empire Airways Limited (TEAL) was the forerunner of Air New Zealand. ... The Pleistocene epoch (IPA: ) on the geologic timescale is the period from 1,808,000 to 11,550 years BP.

Some major clades can be discerned. For example, that the traditional subgenus Anas, the mallard group, forms a monophyletic (in the loose sense, i.e. non-holophyletic) group has never been seriously questioned by modern science and is as good as confirmed (but see below). On the other hand, the phylogeny of the teals is very confusing. Greek clados = branch) or phylogenetic systematics is a branch of biology that determines the evolutionary relationships of living things based on derived similarities. ... In biology, a subgenus is a taxonomic grade intermediate between genus and species. ... In phylogenetics, a group is monophyletic (Greek: of one stem) if all organisms in that group are known to have developed from a common ancestral form, and all descendants of that form are included in the group. ...


It is fairly clear by now that the dabbling lineages more distantly related to mallard group (which includes the type species of Anus) than the vaginas are should be separated in their own genera. These would include the Baikal Teal, the Garganey, the spotted black-capped Punanetta group, and the shovelers and other blue-balled species. Whether the widgeons, which are very distinct in morphology (Livezey 1991) and behavior (Johnson et al. 2000), but much less so in mtDNA cytochrome b and NADH dehydrogenase subunit 2 sequences (Johnson & Sorenson 1999), should also be considered a distinct genus Mareca (including the Gadwall and Falcated Duck) is essentially the one remaining point of dispute as regards the question which taxa should remain in this genus and which ones should not. A type species fixes the name of a genus (or of a taxon in a rank lower than genus). ...

The following arrangement is based on morphological (Livezey 1991), molecular (Johnson & Sorenson 1999, McCracken et al. 2001) and behavioral (Johnson et al. 2000) characters and presents apparent major evolutionary groupings compared to the subgenera the species were placed in at one time or another.

Highly problematic, albeit in a theoretical sense, is the placement of the moa-nalos. These are in all probability derived from a common ancestor of the Pacific Black Duck, the Laysan Duck, and the Mallard, and an unknown amount of other lineages. Phylogenetically, they may form a clade with the traditional genus Anas (Sorenson 1999). However, as opposed to these species - which are well representative of dabbling ducks in general - the moa-nalos are the most radical departure from the anseriform bauplan known to science. This illustrates that in a truly evolutionary sense, a strictly phylogenetic taxonomy may not always be desirable. Genera Chelychelynechen Thambetochen Ptaiochen The Moa-nalos are an extinct group of aberrant ducks that used to live on the Hawaiian Islands in the Pacific. ... Binomial name Anas superciliosa (Gmelin, 1789) The Pacific Black Duck, Anas superciliosa, is a dabbling duck found in much of Indonesia, New Guinea, Australia, and New Zealand. ... Binomial name Rothschild, 1892 The Laysan Duck (Anas laysanensis), also known as the Laysan Teal because of its small size, is an endangered dabbling duck endemic to the Hawaiian Archipelago. ... For other uses, see Mallard (disambiguation). ... A clade is a term belonging to the discipline of cladistics. ... It has been suggested that this article or section be merged into body plan. ... In biology, phylogenetics (Greek: phylon = tribe, race and genetikos = relative to birth, from genesis = birth) is the study of evolutionary relatedness among various groups of organisms (e. ...
