Research Activities

Adjunct Professor Dr. Laura Bolt has co-authored a study entitled "Mantled howler monkeys (Alouatta palliata) modify activity and spatial cohesion in response to seasonality" in the journal BIOS. This article investigates seasonal differences in howler monkey activity budgets and proximity to other monkeys at La Selva Research Station in Costa Rica in order to determine howler monkey flexibility as dry seasons increase in length due to climate change. Bolt and colleagues found that monkeys maintained greater distance from other monkeys and spent less time resting and more time feeding during the dry season (December - April), likely due to increased feeding competition and lower nutritional yields when compared to the wet season (May - November).

Dr. David Samson and PhD candidate Leela McKinnon have a new publication entitled Are We Really in a Sleep Crisis? A Global Look at How We Snooze in Proceedings of the Royal Society B. The CDC calls it an epidemic, but new global sleep data tell a different story. Using biometric sleep tracking (n = 54 studies, 866 participants), we put two big sleep theories to the test. Industrialized societies, despite their tech-driven lifestyles, actually sleep longer and more efficiently. Meanwhile, non-industrial groups boast the strongest circadian rhythms. The real problem? Poor chronohygiene in industrialized settings is throwing our body clocks out of sync. It’s less about lost sleep and more about when—and how—we’re sleeping. Time to rethink the “sleep crisis” narrative! (Posted March 17, 2025)

Adjunct Professor Dr. Laura Bolt has been awarded the "Primates 2024 most-cited paper award" by the journal Primates. This award announcement was published in the November 2024 issue of Primates.

Dr. Bolt won the award for her first-authored paper entitled "Anthropogenic edges impact howler monkey (Alouatta palliata) feeding behaviour in a Costa Rican rainforest", which found that monkeys fed from smaller trees and on poorer quality foods when closer to the human-disturbed edges of a fragmented forest.

Research from the Schreiber Wood Project (SWP), the UTM Anthropology archaeological field school project, has been well represented at two recent conferences. Dr. Sarah Ranlett, now at Yale University, presented a poster, coauthored by Dr. Michael Brand and Dr. Trevor Orchard, entitled “The Schreiber Wood Project at University of Toronto Mississauga: An Historical Southern Ontario Residential Landscape through the Lens of an On-Campus Field School” at the Council for Northeast Historical Archaeology (CNEHA) Annual Meeting, held October 17 to 20, 2024, in New Haven, Connecticut.

The project was also represented by two posters and one oral presentation at the 51^st Annual Symposium of the Ontario Archaeological Society, held October 25 to 27, 2024, in Thunder Bay, Ontario. Undergraduate work-study students Carly Ward (“An assemblage of collaboration: A Student perspective on the Schreiber Wood Project”) and MacKayla Perry-Wessler (“Earthly possessions: Analyzing terracotta flowerpot variation from late 19th-century Mississauga”) presented posters based on their ongoing work with the SWP collections, while Trevor Orchard presented a paper, coauthored with Michael Brand and Sarah Ranlett, entitled “The Schreiber Wood Project: Teaching Archaeology, Facilitating Student Research and Engagement, and Understanding a Late-19^th Century Euro-Canadian Occupation in Mississauga”. 

These recent poster presentations, along with all previous posters and publications from the project, can be found on the Schreiber Wood Project Publications and Posters web page. (Posted November 7, 2024)

Adjunct Professor Dr. Laura Bolt has co-authored a study entitled "Mantled howler monkeys (Alouatta palliata) alter activity and spatial cohesion across a continuous forest and forest fragment in Costa Rica" in the journal Primates. This article compares howler monkey activity budgets and proximity to other monkeys across a small rainforest fragment and a large continuous rainforest in Costa Rica in order to determine how human-caused forest fragmentation impacts primate behavioural ecology.  Bolt and colleagues found that monkeys spent more time feeding and less time in close proximity to other monkeys when in the fragmented forest, likely due to the poorer-quality vegetation in the forest fragment.

Dr. Esteban Parra is listed as a co-author in a reviewed pre-print published in the journal eLife. The paper, which includes multiple authors from the SCOURGE consortium and the COVID-19 Host Genetic Initiative, describes the results of the largest genome-wide association study of COVID-19 hospitalization conducted in Latin America, comprising more than 4,000 hospitalized COVID-19 cases. The study identified four significant associations, including two novel genomic regions. (Posted March 18, 2024)

Dr. Esteban Parra is listed as a co-author in a major study focused on the genetics of type 2 diabetes (T2D) published in the prestigious journal Nature. The article includes authors from institutions throughout the world, working under the umbrella of the newly established Type 2 Diabetes Global Genomics Initiative, and reported the results of a genome-wide association study including more than 2.5 million individuals. The study identified 1,289 independent association signals that map to 611 different genomic regions (including 145 previously unreported regions). Importantly, the genetic data identified different clusters of signals characterized by different cardiometabolic traits, highlighting the aetiological heterogeneity of T2D. (Posted March 18, 2024)

Adjunct Professor Dr. Laura Bolt published three articles in the last month.

Dr. Bolt was lead author on a study published in American Journal of Primatology showing that two monkey species in Costa Rica change their social behaviour when in human-altered areas of forest. Media coverage of the paper can be found at U of T News.

Dr. Bolt was a co-author for a paper in Conservation Letters detailing the importance of funding tropical field stations to enable effective biodiversity conservation. Media coverage of this paper can be found at EurekAlert.

Dr. Bolt was also co-author on a study in Primate Conservation that compared the population size of mantled howler monkeys in two different areas of Costa Rica, a small forest fragment and a large continuous forest, and found that monkey population density was much higher in the small fragment. This attests to their resilience in degraded landscapes, but also has implications for their long-term conservation.  (Posted March 18, 2024)
