Valeria Vergara, PhD

Dr. Vergara holds a BSc in Biology and a Masters in Behavioral Ecology, both from Trent University in Ontario, and a PhD in Zoology from the University of British Columbia.

She is particularly interested in the communicative and perceptual capacities of marine mammals and the conservation implications of such capacities. In the last two decades she has participated in a diverse array of cetacean field studies, including humpback whales, killer whales, Guiana dolphins, narwhals and beluga whales in various areas of Canada.

Her doctoral research was the first to document how beluga calves develop their rich repertoire of vocalizations, and to identify contact calls used to maintain group cohesion and mother-calf contact, critical in an underwater environment where animals cannot rely on vision. More recently, she paired underwater recordings with aerial drone footage to provide preliminary evidence that beluga contact calls may be individually distinctive and function as “acoustic name tags” and she is currently working in the St Lawrence Estuary to corroborate this finding. Her most recent study illustrated how anthropogenic noise affects the communication range of adult and newborn calls in endangered St Lawrence belugas, and showed that masking of the quiet, underdeveloped calls of neonates by noise can impair mother-calf contact.

Her work continues to address the challenges that sound-centered species face in their increasingly noisy environment, and has been featured in various documentaries, magazines and newspapers including National Geographic, The Nature of Things, New Scientist, The Globe and Mail, and CBC Radio.
