Cahill Lab, March 2021.

James F. Cahill (JC)

Professor

JC has been in the Department of Biological Sciences at the University of Alberta since 1999. His research interests are broad, as evidenced by his publication record. Constant themes include conceptually grounded experimental tests of fundamental questions in ecology and conservation biology, root ecology, plant behavioural ecology, and community assembly and function.

Baka Amgaa

Ph.D. Candidate

Baka is interested in the effects of precipitation variability and grazing on plant community structure and function and ecosystem services they provide. His research explores plant root response to growing season drought and defoliation in a factorial experiment and how the functioning of plant roots explains differences in plant communities in responses to these treatments.

Jessica Grenke

Ph.D. Candidate

Jessica is researching the functional consequences of grazing management on plant communities. Her doctoral thesis tackles this topic from operational (via surveys of working ranches across Western Canada), mechanistic (via a controlled mesocosm study), and theoretical perspectives.

Emily Holden

Ph.D. Student

Emily is broadly interested in plant coexistence and competition, and how we can use plant functional traits as a tool to learn about community assembly processes. Her research is field-based in central Alberta. After completing my BSc with Specialization in Ecology at U of A in 2018, Emily worked in municipal sustainability before beginning her graduate studies in September 2019. She is passionate about scientific communication, community engagement, and conservation.

Habba Mahal

M.Sc. Student

Habba is interested in how the interplay between nutrients, neighbour presence, and neighbour identity affects plants’ decisions when placing their roots and shoots, specifically wheat. Prior to her MSc, she completed a BSc in Biology from the U of A in 2018, conducting research in plant genomics, arctic herbivory, paleobotany, and plant-plant interactions prior to graduation. When not washing or weighing root samples, she can be found knitting, hiking, or sleeping in the nearest hammock.

Kenny Oppon

M.Sc. Student

Kenny is interested in the various processes which affect the structure of plant communities. His current research focuses on understanding the interplay between plant communities and their soils and how this relationship can help understand the diversity observed within plant communities.

Tianna Barber-Cross

MSc student (Fall 2021)

Elly is pursuing a BSc degree, double majoring in biology and psychology. She has been a member of the lab since 2020, and is currently working on her first research project.
