Trina Rytwinski

Postdoctoral Researcher

Trina’s research focuses on understanding the circumstances in which anthropogenic impacts affect wildlife populations. She is particularly interested in determining which species or species groups are most vulnerable to human impacts, and determining ways to mitigate negative effects. Most recently, her research has focused on two themes: (1) determining ways to improve knowledge on the influence of mitigation measures on wildlife populations through experiments, and (2) using evidence synthesis to inform management decisions. Trina is currently working with Dr. Steven Cooke and Dr. Joseph Bennett with the Canadian Centre for Evidence-Based Conservation involved with conducting evidence synthesis and meta-analysis.
