TL;DR: In this paper, the authors compared bat diversity and movement across six types of tree cover within an agricultural landscape in central Nicaragua, including secondary forests, riparian forests, forest fallows, live fences, pastures with high and low tree cover, respectively.
Abstract: Although agriculture dominates much of Central America, little is known about the bat assemblages that occur within agricultural landscapes and how bats use different types of tree cover within these landscapes. Using mist-nets and a mark-recapture protocol, we compared bat diversity and movement across six types of tree cover within an agricultural landscape in central Nicaragua. The tree cover types surveyed included secondary forests, riparian forests, forest fallows, live fences, pastures with high tree cover and pastures with low tree cover. We captured a total of 3084 bats of 39 species, including two new species records for the country (Lonchorhina aurita and Molossops greenhalli). Of these, 2970 bats and 27 species were in the Phyllostomidae family. There were significant differences in mean species density, abundance and evenness of phyllostomid bats across the different types of tree cover, but not in bat diversity. Riparian forests had the highest mean species density and bat abundance per plot. In contrast, mean bat abundance and species density were lowest in pastures with low tree cover. Of the 1947 phyllostomid bats marked, a total of 64 bats of eight species were recaptured. The average linear distance between extra-site recaptures was 2227 m (± 228 SE) and the maximum distance was 10.6 km. Bats were recorded moving between almost all types of tree cover, and especially to and from riparian forests. Our study suggests that agricultural landscapes retaining a heterogeneous tree cover may maintain a diverse bat assemblage, and that bats visit and use a variety of tree cover types within the agricultural matrix.

TL;DR: Divergence analysis suggested a Paleocene origin for the family and a split between molossids in the Old World and New World around 29 million years ago and monophyly of most genera was supported.
Abstract: Previous understanding of the relationships among genera of bats in the family Molossidae was based largely on phenetic analyses of morphological data. Relationships among the genera of this family have not been tested with molecular data and, thus, the objective of this study was to construct a phylogeny of representative members of free-tailed bats using DNA sequence data from 1 mitochondrial locus (Nicotinamide adenine dinucleotide dehydrogenase subunit 1 [ND1]) and 3 nuclear loci (dentin matrix protein 1 exon 6 [DMP1], beta fibrinogen intron 7 [bFIB], and recombination activating gene 2 [RAG2]) for members of the subfamily Molossinae and outgroups from the families Vespertilionidae and Natalidae. Data for each gene were analyzed separately using maximum-likelihood and Bayesian methods and also analyzed in a single combined analysis of a total of 3,216 base pairs. Divergence times were estimated from the combined data set using BEAST analysis. Few intergeneric relationships were significantly supported by mitochondrial data; however, monophyly of most genera was supported. Nuclear results supported a Chaerephon–Mops clade; a New World clade consisting of Eumops, Molossus, Promops, Molossops (including Neoplatymops), Cynomops, and Nyctinomops; and a basal divergence for Cheiromeles. Divergence analysis suggested a Paleocene origin for the family and a split between molossids in the Old World and New World around 29 million years ago. Generally, relationships recovered in our analyses reflected biogeographic proximity of species and did not support the hypotheses of relationship proposed by morphological data.

TL;DR: This analysis supports two main clades of molossids, both of which mingle Old World and New World taxa and recommends that the subgenera of Molossops sensu lato and Austronomus be recognized at the generic level.

TL;DR: A combination of morphometric analyses for quantifying size variation and molecular data for reconstructing the evolutionary history within Cynomops showed support for the autapomorphy of white venter as diagnostic for C. planirostris, although there was some overlap in size with the slightly larger, dark-venter C. paranus.
Abstract: Cynomops (dog-faced bat) generally is regarded as either a monophyletic genus or, in some cases, a subgenus of Molossops. Species limits and phylogenetic relationships within Cynomops, however, remain unresolved due primarily to subtle morphological differences and similarity in size of the small taxa. We used a combination of morphometric analyses for quantifying size variation and molecular data for reconstructing the evolutionary history within Cynomops. Rooting the tree with Eumops hansae produced a clade of Molossops neglectus and M. temminckii that was sister to a monophyletic Cynomops clade. The most parsimonious topology (in parenthetical notation) for Cynomops was (((paranus + planirostris) + (greenhalli + abrasus)) + mexicanus). Molecular analysis supports the autapomorphy of white venter as diagnostic for C. planirostris, although there was some overlap in size with the slightly larger, dark-venter C. paranus. Cynomops greenhalli was intermediate in size between C. paranus and C. mexic...
