Objectives. The epizootiology of White Nose Syndrome (WNS) in bats is best described as partially understood. Indeed, there are uncertainties and questions about the pathogenesis of the disease although it is understood that the fungi Geomyces sp. play a significant role in the onset and progression of the disease. The purpose of this workshop was to develop modeling directions to help assist in the understanding of the temporal and spatial scales, the pathology, and the physiology of bats during WNS stress and ultimately to lead to managed control of the disease.

Summary Report. The NIMBioS Investigative Workshop on White Nose Syndrome in Bats (WNS) was held on June 30 – July 2, 2009 with 37 participants from all over the United States. The participants included a diverse array of academicians (primarily theoreticians and biologists), wildlife managers from NGOs, and state and federal government representatives. The focus of the workshop was to understand and mitigate WNS, which is now recognized as the major threat to bats in North America. The workshop was preceded by a webinar held on June 25 featuring 12 speakers who provided background materials necessary for the workshop. The workshop itself consisted of breakout discussion groups that focused on specialized topics and themes, and plenary discussions that focused on results and mitigation needs. Breakout discussion sessions included modeling and fungi, modeling and bat ecology relevant to WNS, modeling perspectives and utility to WNS, and modeling and management.
Recognitions and recommendations of the workshop include the following:
WNS Plans for the Future. Immediate time scale plans include organizing groups of workshop participants to meet a July 31, 2009 deadline for proposals for a special U.S. Fish and Wildlife Service funding initiative on WNS. At this stage no modeling groups have actively pursued funding for WNS research, but with impetus from this workshop, at least one modeling proposal will address this RFP. Another group that has emerged from the workshop is exploring chemical and veterinary intervention to the spread of the disease. Plans were presented to convene a small group of modelers and biologists to organize the modeling efforts for WNS, hopefully through the auspices of NIMBioS. In August, we plan to present a proposal to NIMBioS that will form a working group on WNS. This group will be a select but diverse group including several participants from the workshop.

NIMBioS Investigative Workshops focus on broad topics or a set of related topics, summarizing/synthesizing the state of the art and identifying future directions. Workshops have up to 35 participants. Organizers and key invited researchers make up half the participants; the remaining participants are filled through open application from the scientific community. Open applicants selected to attend are notified by NIMBioS within two weeks of the application deadline. Investigative Workshops have the potential for leading to one or more future Working Groups. Individuals with a strong interest in the topic, including post-docs and graduate students, are encouraged to apply. If needed, NIMBioS can provide support (travel, meals, lodging) for Workshop attendees, whether from a non-profit or for-profit organization.
A goal of NIMBioS is to enhance the cadre of researchers capable of interdisciplinary efforts across mathematics and biology. As part of this goal, NIMBioS is committed to promoting diversity in all its activities. Diversity is considered in all its aspects, social and scientific, including gender, ethnicity, scientific field, career stage, geography and type of home institution. Questions regarding diversity issues should be directed to email@example.com. You can read more about our Diversity Plan on our NIMBioS Policies web page. The NIMBioS building is fully handicapped accessible.
