Myotis planiceps (flat-headed myotis) was known from only 3 specimens collected from 3 different sites in the states of Coahuila, Nuevo Leon, and Zacatecas, Mexico, since its discovery in 1952. The last specimen was collected in 1970; in 1996, after efforts to recollect samples failed, the species was listed as extinct. However, an expedition in 20...

Here we present a set of RNA-based probes for whole mitochondrial genome in-solution enrichment, targeting a diversity of mammalian mitogenomes. This probes set was designed from 7 mammalian orders and tested to determine the utility for enriching degraded DNA. We generated 63 mitogenomes representing five orders and 22 genera of mammals that yield...

We present the first comprehensive taxonomic revision and review the biology of the olingos, the endemic Neotropical procyonid genus Bassaricyon, based on most specimens available in museums, and with data derived from anatomy, morphometrics, mitochondrial and nuclear DNA, field observations, and geographic range modeling. Species of Bassaricyon ar...

Emerging infectious diseases are one of the foremost contemporary threats to biodiversity conservation. Outbreaks of novel pathogens can lead to extinction of host populations, loss of gene flow due to extirpation, and bottlenecks in host populations with surviving individuals. In outbreaks with survivors, pathogens can exert strong selection on ho...

North America is recognized for the exceptional richness of rabies virus (RV) wildlife reservoir species. Management of RV is accomplished through vaccination targeting mesocarnivore reservoir populations, such as the raccoon (Procyon lotor) in Eastern North America. Raccoons are a common generalist species, and populations may reach high densities...

Ultraconserved Elements (UCEs) have been useful to resolve challenging phylogenies of non-model clades, unpuzzling long-conflicted relationships in key branches of the Tree of Life at both deep and shallow levels. UCEs are often reliably recovered from historical samples, unlocking a vast number of preserved natural history specimens for analysis....

Introduced into Hawaii in the early 1900s, the Japanese white-eye or warbling white-eye (Zosterops japonicus) is now the most abundant land bird in the archipelago. Here, we present the first Z. japonicus genome, sequenced from an individual in its invasive range. This genome provides an important resource for future studies in invasion genomics. W...

Here we present the initial comparison of the nuclear genomes of the North American raccoon (Procyon lotor) and the kinkajou (Potos flavus) based on draft assemblies. These two species encompass almost 21 million years of evolutionary history within Procyonidae. Since assemblies greatly impact downstream results such as gene prediction and annotati...

Tree squirrels (Sciurinae, Sciurini) represent a diverse radiation that successfully colonized Europe, Asia and the Americas during the Miocene-Pliocene, but information on their evolutionary history remains unclear. In the Neotropics, they have been shown to exhibit the highest rate of diversification amongst all arboreal squirrels, with strikingl...

Background: Tree squirrels (Sciuridae, Sciurini), in particular the highly diverse Neotropical lineages, are amongst the most rapidly diversifying branches of the mammal tree of life but also some of the least known. Negligence of this group by systematists is likely a product of the difficulties in assessing morphological informative traits and of...

Prairie dogs (genus Cynomys) are a charismatic symbol of the American West. Their large social aggregations and complex vocalizations have been the subject of scientific and popular interest for decades. A large body of literature has documented their role as keystone species of western North America's grasslands: They generate habitat for other ve...

Genes of the major histocompatibility complex (MHC) play a primary role in resistance to infectious disease and have been implicated in mate choice and recognition of close relatives. We describe genetic diversity at three MHC class II genes in urban and non-urban populations of San Joaquin kit fox (Vulpes macrotis mutica), an endangered canid ende...

Microscopy and precise observation are essential skills that are challenging to teach effectively to large numbers of undergraduate biology students. We implemented student-driven digital imaging assignments for microscopy in a largeenrollment laboratory for organismal biology. We detail how we promoted student engagement with the material and how...

This article documents the addition of 512 microsatellite marker loci and nine pairs of Single Nucleotide Polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Alcippe morrisonia morrisonia, Bashania fangiana, Bashania fargesii, Chaetodon vagabundus, Colletes floralis, Colu...
