A conservative interpretation of the molecular data is that island populations of Artibeus jamaicensis, although isolated geographically, are not isolated genetically, and simulations of gene trees within a population tree suggest that lineage sorting is an unlikely explanation for the observed pattern of nonmonophyly.
Phylogenetics and Phylogeography of the Artibeus jamaicensis Complex Based on Cytochrome-b DNA Sequences
Results document that A. jamaicensis (sensu Simmons 2005) comprises 3 monophyletic assemblages that are separated phylogenetically by the presence of A. lituratus, A. obscurus, and A. planirostris, and studies of the nuclear genome will be required to understand the biological implications of these patterns in the mitochondrial genome.

The dynamic process of landscape change on Madagascar has shaped the distribution of a targeted clade of mouse lemurs and how phylogenetic and population genetic patterns in these small primates can reciprocally advance the authors' understanding of Madagascar's prehuman environment is attempted.
Systematics of Malaysian woolly bats (Vespertilionidae: Kerivoula) inferred from mitochondrial, nuclear, karyotypic, and morphological data
Examining species boundaries using data from multiple independent sources is an appropriate and robust method to identify genetically isolated evolutionary units and indicates a late Oligocene to early Miocene origin of the Kerivoulinae with intraspecific diversification events coinciding with the late Pliocene and Pleistocene epochs in at least 6 species.

A Caribbean species of bat (Artibeus schwartzi) has a nuclear genome derived from two nonsister but congeneric species and a mitochondrial genome that is from a third extinct or uncharacterized congener, demonstrating the phenomenon of speciation by hybridization in mammals is possible in nature.
Genetic Diversity of Neotropical Myotis (Chiroptera: Vespertilionidae) with an Emphasis on South American Species
An assessment of the diversity in New World Myotis by analyzing cytochrome-b gene variation from an expansive sample ranging throughout North, Central, and South America provides evidence that the perception of lower species richness in South America is largely due to a combination of cryptic morphological variation and insufficient sampling coverage in genetic-based systematic studies.
Molecular Evolutionary Characterization of a V1R Subfamily Unique to Strepsirrhine Primates
The most extensive sample of vomeronasal receptor class 1 (V1R) sequences ever generated for a diverse yet phylogenetically coherent group of mammals, the tooth-combed primates (suborder Strepsirrhini).
Speciation Dynamics of the Fruit-Eating Bats (Genus Artibeus): With Evidence of Ecological Divergence in Central American Populations
The data from Artibeus indicate that multiple speciation processes underlie extant levels of diversity within the genus and provide further evidence for complex origins of the Neotropical fauna and contribute to a greater understanding of the natural processes underlying the origin of species.

It is concluded that the epigenetic dysregulation of Alu elements can ultimately disrupt mitochondrial homeostasis within the CNS and is a plausible source for the incipient neuronal stress that is consistently observed across a spectrum of sporadic neurological and neurodegenerative disorders.
Application of circular consensus sequencing and network analysis to characterize the bovine IgG repertoire
This data indicates that unusually long CDR3 sequences are not unique to IgM antibodies in cattle, and hypothesizes that network or cluster-based analyses of expressed antibody repertoires from controlled challenge experiments will help identify novel natural antigen binding solutions to specific pathogens of interest.
