Vicariance or dispersal? Historical biogeography of three Sunda shelf murine rodents (Maxomys surifer, Leopoldamys sabanus and Maxomys whiteheadi)
TLDR
The hypothesis that Pleistocene land bridges enabled widespread movements in three rain-forest-restricted murine rodents of the Sunda shelf is tested and a deep history of vicariant evolution that may correspond with the Pliocene fragmentation of theSunda block is suggested.
DNA barcoding of Neotropical bats: species identification and discovery within Guyana
TLDR
The present study validates the effectiveness of barcoding for the identification of regional bat assemblages, even highly diverse tropical faunas.
Species diversity of bats (Mammalia: Chiroptera) in Iwokrama Forest, Guyana, and the Guianan subregion: implications for conservation
Fourteen species of bats are reported for the first time from Guyana (Saccopteryx gymnura, Micronycteris brachyotis, M. homezi, Lichonycteris obscura, Anoura latidens, Vampyressa pusilla, Vampyrodes
Toward a Molecular Phylogeny for Peromyscus: Evidence from Mitochondrial Cytochrome-b Sequences
TLDR
Analysis of DNA sequences from the mitochondrial cytochrome-b gene of 44 species of deer mice used to develop a molecular phylogeny for Peromyscus depicted strong support for a clade placing Habromys, Megadontomys, Neotomodon, OsgoodomYS, and Podomys within Peromycus.
Bat community structure at Iwokrama Forest, Guyana
TLDR
It is concluded that resource partitioning and species packing differentially affect relative size in tropical bats, and are better summarized and analysed in three dimensions.
Molecular Differentiation of Large Species of Fruit-Eating Bats (Artibeus) and Phylogenetic Relationships Based on the Cytochrome b Gene
TLDR
Contrary to previous hypotheses of species limits based on a presumed intergradation in body size, A. jamaicensis and A. planirostris do not form a monophyletic group, refuting their conspecificity and supporting an earlier study concluding that these two taxa represent separate morphological populations.
Molecular phylogeny of New World sheath‐tailed bats (Emballonuridae: Diclidurini) based on loci from the four genetic transmission systems in mammals
TLDR
There is better resolution and support for the more slowly evolving nuclear introns including a New World clade, indicating a single origin of emballonurid bats in the Neotropics, and one novel subtribe has a hard basal polytomy that is unresolved for all of the nuclear partitions, suggesting a rapid burst of evolution during the diversification of genera.
Vocal Stereotypy and Singing Behavior in Baiomyine Mice
TLDR
Examination of morphological and molecular data supports a close relationship between the 2 baiomyine genera, and identifies song as a complex behavior that further underpins the monophyly of the Baiomyini.
NEW SPECIES OF DISK-WINGED BAT THYROPTERA AND RANGE EXTENSION FOR T. DISCIFERA
TLDR
A new species of disk-winged bat (Thyroptera) is described from the savannah habitats of the Cerrado in Brazil and Rupununi in Guyana that has distinct countershading with dark brown dorsal fur that is in contrast to pale brown ventral fur with frosted tips.
Molecular phylogenetics of Reig's short-tailed opossum (Monodelphis reigi) and its distributional range extension into Guyana
TLDR
Reig's short-tailed opossum (Monodelphis reigi) was recently described morphologically and a molecular phylogenetic analysis of mitochondrial cytochrome b sequence variation suggests that there was a dispersal event from the Andes to the Guiana Highlands in the Miocene that gave rise to M. reigi.
