All three tests identified cases in which improving the reconstruction model would improve the phylogenetic accuracy of the individual partitions, and the most useful was the incongruence length difference test (ILD), also called the partition homogeneity test.
Arthropod relationships revealed by phylogenomic analysis of nuclear protein-coding sequences
This work presents strongly supported results from likelihood, Bayesian and parsimony analyses of over 41 kilobases of aligned DNA sequence from 62 single-copy nuclear protein-coding genes from 75 arthropod species, providing a statistically well-supported phylogenetic framework for the largest animal phylum.

The patterns of persistence in North America indicate that other life-history traits, including mechanisms of dispersal, may be more important for surviving dramatic environmental and climatic change.
Is congruence between data partitions a reliable predictor of phylogenetic accuracy? Empirically testing an iterative procedure for choosing among phylogenetic methods.

The relationship between phylogenetic accuracy and congruence between data partitions collected from the same taxa was explored for mitochondrial DNA sequences from two well-supported vertebrate phylogenies and six-parameter parsimony methods show a consistently positive relationship between congruency and accuracy.
Evolution of king crabs from hermit crab ancestors
It is estimated that loss of the shell-living habit and the complete carcinization of king crabs has taken up to 25 million years, and molecular evidence is presented that king crabs are not only descended from hermit crabs, but are nested within the hermit crab genus Pagurus.
Class-level relationships in the phylum Cnidaria: molecular and morphological evidence.
Analysis of class-level relationships based on 18S ribosomal DNA sequences, mitochondrial 16S rDNA sequence, mitochondrial genome structure, and morphological characters unifies the classes possessing a medusa stage, leaving the holobenthic Anthozoa basal within the phylum.
Resolving arthropod phylogeny: exploring phylogenetic signal within 41 kb of protein-coding nuclear gene sequence.
This study attempts to resolve relationships among and within the four basal arthropod lineages and to assess the widespread expectation that remaining phylogenetic problems will yield to increasing amounts of sequence data.

The structure of the mitochondrial genome in representatives of the four extant cnidarian classes and in the phylum Ctenophora is surveyed, finding that all anthozoan species tested possess mtDNA in the form of circular molecules, whereas all scyphozoan, cubozoa, and hydrozoan species tested display mt DNA in the forms of linear molecules.
DIVERSITY IN THE WEAPONS OF SEXUAL SELECTION: HORN EVOLUTION IN THE BEETLE GENUS ONTHOPHAGUS (COLEOPTERA: SCARABAEIDAE)

This work uses partial sequences from four nuclear and three mitochondrial genes to develop a phylogenetic hypothesis for a worldwide sample of 48 species from the dung beetle genus Onthophagus and characterize the evolutionary radiation of beetle horns.
