The Faculty of Science hosts public lectures during the academic year that address a scientific issue of the day as well as bring to campus well-known scientists from around the world. Established in 2002, the Discovery Lecture is designed to showcase and promote excellence in science journalism. Sponsored jointly by the Faculty of Science and the School of Journalism, the lecture is held annually in the winter semester and is free and open to the public.

Abstract

Understanding how ecological and social context shapes the evolution of species is a major focus in biology, with implications for understanding individual variation, species diversity and resilience to environmental change. Given that the currency of evolution is reproduction, sexual behaviours and traits can be key to understanding these dynamics.

Maydianne Andrade discusses how her fundamental research on sexual behaviours and plasticity has leveraged the extreme mating systems of cannibalistic black widow spiders to gain insights into links between ecology and evolution.  Of particular interest is how traits related to behaviour, life history, and physiology can shift as a function of cues that indicate challenges to fitness in varied habitats.

Interwoven in this narrative is a parallel story about navigating, understanding, acknowledging, and then embracing what is means to be a scientist who is also a Black woman. Her experiences highlight the importance of role models, knowledge translation and outreach, and how the communication skills and perceived authority of scientists can be deployed, with intention, caution, and care, to engage with broader audiences.

Professor Andrade earned her Ph.D. in Neurobiology and Behavior at Cornell University and is a Professor in the Department of Biological Sciences at the University of Toronto Scarborough (UTSC) and in the Graduate Department of Ecology & Evolutionary Biology at UT St. George. As a Canada Research Chair in Integrative Behavioural Ecology (2007 to 2018), Fellow of the Animal Behaviour society, and elected member of the American Academy of Arts & Sciences, Professor Andrade’s fundamental research has a primary focus on the evolution of mating behaviour and species diversity, using black widow spiders as models. Since 2010, she has also been engaged in knowledge translation with respect to the effects of bias on diversity and inclusion in academia. In 2019 she was awarded the Ludwik and Estelle Jus Memorial Human Rights Prize by the University of Toronto’s Alumni Association in recognition of the impact of her work, including founding and acting as co-Chair of TIDE (the Toronto Initiative for Diversity and Excellence). In 2020, she joined with other faculty to create the Canadian Black Scientists Network, for which she is currently serving as President. A strong proponent of outreach and public communication to encourage broad engagement in science and equity, Prof. Andrade has served as a guest on CBC radio (IDEAS, Quirks and Quarks), hosted an episode of The Nature of Things (First Animals), and most recently has partnered with University of Toronto Communications to create the podcast The New Normal.
