The identity, distribution, and impacts of non-native apple snails in the continental United States
Clarifying species identifications permits a more accurate assessment of introduction histories and distributions, and provides a very different picture of the tempo and pattern of invasions than was inferred when the three species with channeled sutures were considered one.
Deducing the pattern of arthropod phytogeny from mitochondrial DNA rearrangements
THE origins of arthropods and the phylogenetic relationships among their three major living groups (atelocerates, crustaceans and chelicerates) are vigorously contended. To help resolve this, we…
EVOLUTIONARY HISTORY OF NORTHERN HEMISPHERE NUCELLA (GASTROPODA, MURICIDAE): MOLECULAR, MORPHOLOGICAL, ECOLOGICAL, AND PALEONTOLOGICAL EVIDENCE

A hypothesis of phylogenetic relationships for all of the currently recognized species of northern hemisphere Nucella is presented, based on an analysis of 718 base pairs of nucleotide sequence from the mitochondrial cytochrome b gene.

This first phylogenomic approach for this important group of molluscs is presented, including novel transcriptomic data for 31 bivalves obtained through an RNA-seq approach, and the results provide a well-resolved, robust phylogenetic backbone for Bivalvia with all major lineages delineated.
Developing model systems for molecular biogeography: Vicariance and interchange in marine invertebrates
This chapter focuses on studies of littoral marine invertebrates in three well-studied marine model systems, and presents molecular divergence, population genetic, and in some cases, paleontological evidence that sister taxa in neighboring areas likely diverged at different times.
Investigating the Bivalve Tree of Life – an exemplar-based approach combining molecular and novel morphological characters

An analysis of the informativeness of morphological characters showed that sperm ultrastructure characters are among the best morphological features to diagnose bivalve clades, followed by characters of the shell, including its microstructure.
Sessile snails, dynamic genomes: gene rearrangements within the mitochondrial genome of a family of caenogastropod molluscs
Evidence is provided that the lability of the molluscan mitochondrial genome extends to the family level by describing extensive gene order changes that have occurred within the Vermetidae, a family of sessile marine gastropods that radiated from a basal caenogastropod stock during the Cenozoic Era.
Beyond area relationships: Extinction and recolonization in molecular marine biogeography
This work sharpen the focus of vicariance biogeography, and attempts to identify organismal characteristics that unite sets of taxa with congruent histories in two well-studied model systems: the southeastern United States and the trans-Arctic interchange through the Bering Strait.
Choosing the best genes for the job: the case for stationary genes in genome-scale phylogenetics.
It is illustrated through a series of analyses that the stationary gene partition is superior to the nonstationary partition, recovering the underlying phylogeny with many fewer genes, and the conclusion of Rokas et al. regarding the superiority of random sampling of orthologous nucleotides relative to contiguous sequences for phylogenetic analysis is largely an artifact of different bootstrap treatments for these two sampling schemes.
Changing identities: tRNA duplication and remolding within animal mitochondrial genomes

It is demonstrated that inferring tRNA orthologs among taxa by using anticodon triplets and deduced secondary structure can be misleading: through a process of tRNA duplication and mutation in the anticodon doublet, remolded leucine (LUUR) tRNA genes have repeatedly taken over the role of isoaccepting LCUN leucines within metazoan mtDNA.
