is currently recognized as a highly polyphyletic
genus and many attempts of new circumscription of smaller genera are in progress (e.
The taxonomy of the group has been problematic and several studies suggested that Myrmotherula is polyphyletic
(Belmonte-Lopes et al.
These species group members emerged as polyphyletic
in maximum likelihood phylograms based on morphological characters and concatenated analyses of cytochrome oxidase I and arginine kinase genes (Hansen et al.
Other structural differences also indicate that the 'corynexochids' is a polyphyletic
The Polychaeta are a polyphyletic
class of annelid worms, generally marine.
These data also reveal that Chilatherina and Glossolepis of northern New Guinea as presently understood are polyphyletic
and most likely should be integrated into the genus Melanotaenia, which is the oldest name for the group.
2008), however, and other genetic analyses suggest polyphyletic
origins for emmer (Allaby et al.
Oral samples from each outbreak are polyphyletic
with respect to strains from their immediate environment, a finding consistent with multiple contamination events or multiclonal infection sources.
Clonal diversity and polyphyletic
origins of hybrid and spontaneous parthenogenetic Campeloma (Gastropoda: Viviparidae) from the southeastern United States.
As already noted by Benson (1938), both subfamilies as presently constituted are probably polyphyletic
The resulting phylogeny confirmed many of the species groups from earlier studies, but more importantly showed that Aquarius was polyphyletic
Recent molecular studies recognized two subtribes of Gentianeae: Swertiinae and Gentianinae (2, 3, 5) and within Swertiinae, Swertia is highly polyphyletic
(2, 3, 4, 5, 6,7).
