The systematics of the Cervidae: a total evidence approach [PDF]
Systematic relationships of cervids have been controversial for decades. Despite new input from molecular systematics, consensus could only be partially reached.

Eumalacostracan phylogeny and total evidence: limitations of the usual suspects [PDF]
Background The phylogeny of Eumalacostraca (Crustacea) remains elusive, despite over a century of interest. Recent morphological and molecular phylogenies appear highly incongruent, but this has not been assessed quantitatively.

Total evidence phylogeny and evolutionary timescale for Australian faunivorous marsupials (Dasyuromorphia) [PDF]
Background The order Dasyuromorphia is a diverse radiation of faunivorous marsupials, comprising >80 modern species in Australia and New Guinea. It includes dasyurids, the numbat (the myrmecobiid Myrmecobius fasciatus) and the recently extinct thylacine (

Total-evidence phylogeny reveals recent crown group radiation and biogeographical history of hamsters [PDF]
Background The systematics of extant hamsters (Cricetinae) have been increasingly clarified, due to advances in molecular phylogenetics. In contrast, their relationships with their fossil relatives have remained relatively unclear.

Total neoadjuvant therapy for rectal cancer: evidence and challenge [PDF]
Recent advances in the management of rectal cancer have dramatically changed the clinical practice of colorectal surgeons because the main focus of rectal cancer treatment has changed from sphincter-saving to an organ-preserving strategies. Modifying the

The Root of Flowering Plants and Total Evidence [PDF]
Support for Amborella as the sole survivor of an evolutionary lineage that is sister to all other angiosperms comes from positions in DNA multiple-sequence alignments that have a poor fit to time-reversible substitution models. These sites exhibit significant levels of homoplasy, compositional heterogeneity, and strong heterotachy.

Acrostilicus Hubbard, 1896 and Pachystilicus Casey, 1905 are North American genera known from only one and two species, respectively, and have never been a subject of a modern revision. In fact, Acrostilicus was not even properly described as its author
