For every scientific study we publish, we'll put the results here! Each study will have a link to the scientific publication as well as a summary of the main findings.
Prugh, L. R., Prashant, M., Reese, E., Kreling, S. E. S., Rohan, I. M., Windell, R. M., Hentati, Y. 2026. Urbanization increases coyote density 9-fold in Washington state despite negative effects of human density within Seattle, USA. Environmental Research Ecology, 5: 035005. https://iopscience.iop.org/article/10.1088/2752-664X/ae9ffd
Main takeaway: Like in most urban places, medium sized carnivores are at higher densities in the city than outside of the city due to more abundant food and reduced apex predator populations.
Kreling, S. E. S., Reese, E. M., Cavalluzzi, O. M., Renouard, A., Long, R. A., Prugh, L. R. 2026. Urbanization drives patterns of individual specialization but not dietary diversity among coyotes. Ecology and Evolution, 16: e74170. https://onlinelibrary.wiley.com/doi/10.1002/ece3.74170
Main takeaway: Urban coyotes specialize less than rural coyotes in Washington, meaning lethal removal may not have the desired effect of eliminating of stopping consumption of unwanted diet items (like pets) since certain individuals do not specialize in targeting pets.
Kreling, S. E. S., Bartholomew, L. Y., Duling, J. R., Tran, T. K., Reese, E. M., Hentati, Y., Schell, C. J., Prugh, L. R. 2026. Feast or famine: How food deserts, wealth and greensapce correlate with coyote diets in Seattle, Washington. People and Nature, 8: 3051-3065. https://besjournals.onlinelibrary.wiley.com/doi/10.1002/pan3.70390
Main takeaway: Seattle coyote diet is extremely varied, but most diet items are not well-explained by ecological or socioeconomic variables.
Hentati, Y., Reese, E. M., Curran, C. C., Miller, E. M., Díaz-Morales, D., Kreling, S. E. S., Verocai, G. G., Prugh, L. R., Prugh, L. R., Schell, C. J., Wood, C. L. 2026. Detection of Echinococcus multilocularis in coyotes in Washington state, USA highlights need for increased global wildlife surveillance. PLoS Neglected Tropical Diseases, 20: e0013502. https://journals.plos.org/plosntds/article?id=10.1371/journal.pntd.0013502
Main takeaway: An important zoonotic parasite was found in coyotes which can affect domestic dogs and immunocompromised humans.

Main takeaway: There are specific genes that we urge future researchers to look at that might make urban coyotes different from non-urban coyotes.
Kreling, S. E. S., Reese, E. M., Cavalluzzi, O. M., Bozzi, N., Messinger, R., Schell, C. J., Long, R. A., Prugh, L. R. 2024. City divided: Unveiling familial ties and population structuring in Seattle's coyote inhabitants. Molecular Ecology, 33: e17427. https://onlinelibrary.wiley.com/doi/10.1111/mec.17427.
Main takeaway: Interstate-5 and the Lake Washington Ship Canal act as barriers for urban coyote movement in Seattle.
Williams, T. D., Kreling, S. E. S., Carlen, E. J., Wilkinson, C. E., Stanton, L. A., Estien, C. O., Schell, C. J. 2024. Understanding the social perceptions of charismatic color morphs. Human Ecology. https://doi.org/10.1007/s10745-024-00492-7
Main takeaway: Humans treat animals differently when they are a unique color.
Carlen, E. J., Estien, C. O., Perkins, D., Goldstein, B. R., Williams, T. D., Caspi, T., Kreling, S. E. S., Hentati, Y., Stanton, L. A., Johnson, R. F., Young, A., Des Roches, S., Schell, C. J. 2024. A framework for contextualizing social-ecological biases in contributory science data. People and Nature, 6: 377-390. https://besjournals.onlinelibrary.wiley.com/doi/full/10.1002/pan3.10592
Main takeaway: Scientists working with community-collected data such as from iNaturalist or eBird, have to account for the underlying biases.
Kreling, S. E. S. 2023. So overt it's covert: Wildlife coloration in the city. BioScience, 73: 333-346. https://academic.oup.com/bioscience/article-abstract/73/5/333/7095303
Main Takeaway: Animals in urban areas may be turning up in more colorations as they have more exposure to pollutants, less high quality food, and different predation pressure that releases traditional constraints (such as camouflage) on coloration.
