Overview

Ray T. Alisauskas is affiliated with Environment and Climate Change Canada in Canada, specializing in environmental sciences with a focus on ecology, parasitology, and atmospheric science. Their research predominantly spans the fields of environmental science and ecology, including ecological modeling and studies on ecology, evolution, behavior, and systematics.

The scientist's work covers a diverse array of topics, notably avian ecology and behavior, wildlife ecology and conservation, and species distribution in relation to climate change. Additional important themes include animal behavior and reproduction, viral infections and their vectors, vector-borne infectious diseases, and aspects of climate variability and models.

Ray T. Alisauskas has published numerous articles across several prominent scientific journals. Frequent venues for their research outputs include Arctic Science, Polar Biology, Ecosphere, Birds of the World, and the Proceedings of the Royal Society B Biological Sciences.

Selected recent publications exemplify the scope of their work:

  • "Taking the beat of the Arctic: are lemming population cycles changing due to winter climate?" (2024, Proceedings of the Royal Society B Biological Sciences)
  • "Local population collapse of Ross's and lesser snow geese driven by failing recruitment and diminished philopatry" (2022, Oikos)
  • "Widespread Exposure to Mosquitoborne California Serogroup Viruses in Caribou, Arctic Fox, Red Fox, and Polar Bears, Canada" (2023, Emerging infectious diseases)
  • "Hopping species and borders: detection of Bartonella spp. in avian nest fleas and arctic foxes from Nunavut, Canada" (2020, Parasites & Vectors)
  • "Plasticity in timing of avian breeding in response to spring temperature differs between early and late nesting species" (2021, Scientific Reports)

They have collaborated extensively with several frequent coauthors, including Dana K. Kellett, Gustaf Samelius, Kayla J. Buhler, Emily Jenkins, and Paul A. Smith, reflecting ongoing research partnerships within related fields.
