An expert jury has recognized Shirey, who was nominated by the GBIF United States delegation, for their effort to address data bias while modelling the long-term impacts of climate and land-use change on a well-known family of organisms in poorly sampled regions: the butterflies (Papilionidea) that inhabit the boreal forests of North America and northern Europe.
Disparities in the availability of biodiversity data across space and time present challenges for modelling, measuring and mitigating threats like climate and land-use change. With the world's boreal forests now facing rapid warming and widespread land conversion, sparsity of data from these high-latitude environments only increases the difficulty and urgency of such challenges.
Combining butterfly data available through GBIF with trait data extracted from literature, Shirey's research both examines a family of organisms particularly sensitive to global change and provides a model for using data with known gaps and biases to analyse high-priority conservation areas. The results synthesize a macroscale study of butterfly richness and composition trends in North American and European boreal forests between 1940 and 2019.
"GBIF-mediated data serves here as the backbone for making inferences about butterfly communities in a time of global change," said Shirey. "The 'pseudo-sampling' technique I apply, alongside accounting for observer behaviors, can help develop best practices for using sparse, opportunistic occurrence records to understand biodiversity dynamics."
"Vaughn is a tremendously creative and independent thinker who has charted their own path since arriving at our lab, so this award is truly well-deserved," said Leslie Ries, Associate Professor of of Biology at Georgetown University. "With their combination of data science skills, passion for serving the community and commitment to high-latitude field work in a vast and logistically challenging ecoregion, Vaughn has all the qualities of a leader for the next generation of ecologists."
“I had the opportunity to supervise and work with Vaughn during their stay in Helsinki under a Fullbright Fellowship," said Pedro Cardoso, curator of arachnids, millipedes and terrestrial molluscs at Luomus, the Finnish Museum of Natural History. "They already had a number of ideas on how to best use GBIF data and overcome their limitations, and I never ceased being impressed by their work capacity. Seeing Vaughn going this far this fast is not really a surprise, but still makes me so happy to see their work recognized with such an important award!”
"I am both impressed with Vaughn’s existing record and their potential for transformational approaches to the use of GBIF data," said Rob Guralnick, curator of Biodiversity of Informatics at the Florida Museum of Natural History and University of Florida Research Foundation Professor. "Vaughn has already established themself as a next-generation leader in eco- and biodiversity informatics, especially given their focus on integrating machine-learning approaches into knowledge synthesis and citizen science-based work."
Shirey is the second U.S. national to win the award, after Kate Ingenloff (2018), the first from Georgetown, and the third nominated by the U.S. delegation to GBIF, following Ingenloff and Andrés Lira-Noriega, a Mexican researcher then studying in the United States, who received an award in 2010, the award's inaugural year.
