The Bat Ecology and Genetics Laboratory promotes research on and conservation of bats in northern Arizona and globally, has over a dozen projects underway currently, and involves a vibrant network of researchers and collaborators. The ecology side of the team is directed by NAU's Carol Chambers, and I direct the genetics side. Dan Sanchez and our star undergrads have been key members of our genetics team since BEGL's inception in 2014.

In recent years, the same tools we use to study bats have been extended to other taxa; you'll see this across web pages.

Bat background
Bats are arguably the least understood mammalian order, despite being one of the most diverse and abundant. Because bats are volant and nocturnal, and many travel great distances nightly or annually, they have until recently been largely scientifically intractable. Genetic and genomic techniques are now part of an emerging arsenal for unravelling the secrets of bats and facilitating their conservation. We aim to leverage these approaches to benefit bat species globally.
Bats are important for many reasons, including the ecological services they provide in the form of insect control (saving U.S. agriculture an estimated $5.7 billion dollars annually), pollination, and seed dispersal.
In the U.S., an emerging disease (White-nose Syndrome, WNS) and new technologies (wind energy) are bringing a new urgency to the study and conservation of bats. Arizona has the 2nd richest bat assemblage (28 spp) in the U.S. (after Texas), is currently WNS-free, and has a growing wind industry. We are well positioned in Flagstaff to study bats because of diverse bat-focused collaborations here (Bat Conservation International, USDA APHIS, Western Bat Working Group), our proximity to natural disturbances (fire) and relevant industry (wind, mining), and our state-of-the-art facilities (PMI, and the Ancient DNA Lab).
Some of our current projects
Species from Feces Initiative: Tools for genetically identifying bats
Bat guano contains an untapped reservoir of information – DNA. Often available even when bats are not present, guano is stationary and easy to collect. We used bioinformatics to generate a DNA mini-barcode that identifies bat species from their feces. We successfully identified primers that PCR-amplify a 202 base pair segment of mitochondrial gene Cytochrome c oxidase I that we have found to be highly discriminatory among Chiroptera globally, usually down to the species level, readily accomodate fecal DNA, and can be scaled up to next generation sequencing technologies. Our tool has enormous application in the U.S., where bats are under threat from white-nose syndrome, and also worldwide, where many bat species are vulnerable or facing extinction. The paper describing this work is here.
Try our database search to see if your favorite bat can be identified to the species level with our DNA mini-barcode!
Diseases: sylvatics and zoonotics
Simultaneous genetic screening for bat species and White-nose Syndrome
WNS has been confirmed as far west as Washington state and Texas. The disease represents a great risk to public lands in the U.S., especially in the west where bats inhabit relatively pristine cave systems that are important for long term persistence of species. As caves and mines (i.e., subterranean habitat) are refuge for both bat and fungus, a practical conservation tool is to sample guano to genetically determine bat species that use roosts and whether the fungus responsible for the disease is present.
For another project in collaboration with Dr. Slava Fofanov, also at NAU, we are using guano to examine microbial transmission dynamics in time and space.
Rabies in an Urban Interface
Flagstaff, Arizona, has experienced periodic bat-variant rabies virus outbreaks in skunks, foxes, and bats for the past ~15 years. With the USDA APHIS, we are evaluating the seasonal changes in population density of two species of bats (Eptesicus fuscus and Myotis occultus), estimating the amount of active infection by RABV in these species through the year, and determining whether E. fuscus maternity roosts are composed of related females (fondly called our Rabies and Babies project).
Genetics of a spectacular North American bat
Spotted bats (Euderma maculatum) are arguably the most attractive bat species in North America, with long ears and three white spots on otherwise black pelage. Yet they're cryptic (nocturnal, volant, and roost solitarily), and thus their biology remains largely undescribed. Only 35 specimens were known to science before the mid-1960s. Hence, they are excellent candidates for elucidation of aspects of population biology and natural history via genetic tools. We sought to determine the degree of historical and contemporary regional movement. To this end we developed 17 microsatellite markers and are employing them in tandem with mitochondrial markers to genotype 60 museum specimens, 70 DNA samples that we've collected, and 7 mummies dated to 10,000 years old. Expect 3 papers describing our results this year.
Mines and Windfarms
Mines: The number of mines that now exist in the western U.S. exceeds 600,000 and these structures have created new or increased extent of habitat for bats. Mines can provide stable roosts, prey sources, and drinking water for bats and use of mines by bats can be high. Currently, mines are likely to be gated if they provide habitat for bats. With support of BCI and the BLM, Master's student Abby Tobin identified characteristics of gates that are detrimental or positive to bat activity.
Windfarms: Four factors in northern Arizona create the potential for serious impacts to bat populations if risks are not carefully identified prior to construction of wind facilities: 1) the amazing diversity of bats in the area (≥20 species), 2) the unique types and numbers of roost sites found in canyon areas such as the >300 km long Grand Canyon, 3) the moderate climate that allows year-round occupation and activity for some bat species, and, 4) the use of northern Arizona as flyways for migratory species. Ph. D. student Clarissa Starbuck is conducting a risk analysis of wind facility development to bats in northern Arizona by identifying areas of high risk via acoustic, capture, and radio telemetry techniques. She is identifying migration patterns and routes, characterizing the bat community, and locating key roost sites, which will allow resource managers to identify options to protect habitat for bats in proximity to wind development sites.
