In phylogenetic analyses of molecular sequence data, partitioning involves estimating
independent models of molecular evolution for different sets of sites in a sequence …

Ticks are obligate blood-sucking arachnid ectoparasites from the order Acarina, and many
are notorious as vectors of a wide variety of zoonotic pathogens. However, the systematics …

Background DNA barcoding, ie the use of a 648 bp section of the mitochondrial gene
cytochrome c oxidase I, has recently been promoted as useful for the rapid identification and …

Recently, the role of mitochondrial DNA (mtDNA) sequences in taxonomy and phylogenetic
inference has become contentious, and two extreme viewpoints have emerged, although, as …

Increasing the number of characters used in phylogenetic studies is the next crucial step
towards generating robust and stable phylogenetic hypotheses—ie, strongly supported and …

We analyzed 12 combined mitochondrial and nuclear gene datasets in seven orders of
insects using both equal weights parsimony (to evaluate phylogenetic utility) and Bayesian …

Phylogenetic relationships among major clades of butterflies and skippers have long been
controversial, with no general consensus even today. Such lack of resolution is a substantial …

Ratites are large, flightless birds and include the ostrich, rheas, kiwi, emu, and cassowaries,
along with extinct members, such as moa and elephant birds. Previous phylogenetic …

Morphological and molecular data are currently contradictory over the position of
monotremes with respect to marsupial and placental mammals. As part of a re-evaluation of …

With the aim of supporting ecological analyses in butterflies, the third most species-rich
superfamily of Lepidoptera, this paper presents the first time-calibrated phylogeny of all 496 …
