Rob Colautti - Principal Investigator

Canada Research Chair in Rapid Evolution [CV]

Rob The Anthropocene is marked by several threats to global biodiversity, including climate change, large-scale habitat modification, and long-distance translocation of species across major dispersal barriers (e.g. oceans, mountain ranges, deserts). As a result, species are experiencing environments that are novel with respect to the range of conditions experienced throughout their recent evolutionary history. Rapid evolution in novel environments could prevent extinction, alter species interactions, and ultimately shape the structure and function of ecosystems, yet contemporary evolution and its effects on ecological dynamics are rarely studied in natural populations with a history of human perturbation. Researchers in our group are working hard to understand how and why contemporary evolution occurs in novel environments, and how this influences ecological dynamics.

To help address these questions, we apply cutting-edge advances in next-generation sequencing with tried-and-true methods in basic ecology and quantitative genetics. We combine meticulous field studies at Queen's University Biological Station (QUBS) with global-scale collaborative projects to produce scientific discoveries that are both locally accurate and globally relevant. Understanding the genetic and environmental basis of ecological success in novel environments will be important, not only for reducing the impacts of invasive species, but to improve management of local crop varieties and other vulnerable species that are struggling to persist in the face of rapid global change.

I am interested in the evolution and population genetics of invasive species as well as the underlying genetics of the “mustard oil bomb” in the Brassicaceae. My research focuses specifically on the population genetics of eastern North American garlic mustard, a noxious weed that has invaded forest understories and reduces native plant diversity. To do this, I am utilizing next-generation sequencing and software pipelines to examine genetic differentiation between populations. I am studying the phenology of invasive purple loosestrife and latitudinal flowering clines on the east and west coasts of North America.

Plant invasions provide great opportunities to study evolutionary processes because invasive plants are subjected to both stochastic and deterministic evolutionary forces upon introduction into the new range. Invasive plants are often released from selective pressures present in their native range, which can result in the loss of previously adaptive traits via genetic drift. On the other hand, novel selective pressures in the invaded range can facilitate the evolution of new adaptative traits. The goal of my research is to identify traits that have evolved following an invasion and determine whether these traits evolved because of stochastic processes or natural selection. Garlic Mustard (Alliaria petiolata) is a member of the Brassicaceae family, native to Eurasia. In the 19th century, it was introduced into North America and has since spread across much of the continent. I use genotypes collected throughout the invasive (North American) range and I subject these genotypes to relevant selective pressures to determine which traits may be adaptive in the invaded range. I then determine whether these adaptive traits are expressed in natural populations with a corresponding selective pressure. The main focus of my research is the evolution of glucosinolate and flavonoid compounds in A. petiolata, particularly their role in intra- and interspecific competition.

Natural selection on individual traits often fails to produce adaptive evolution because of constraints arising from trait correlations. In my research, I study how correlations among life history traits in the North American invasive wetland plant Lythrum salicaria are generated during development. I conducted field surveys across a 1000km latitudinal transect to document phenotypic variation among 20 populations in Canada and the United States, then planted a common garden at Queen's University Biological Station (QUBS) to capture genetic variation among traits such as size at flower and time to flower. This intensive field sampling allows me to explore the developmental basis for genetic constraints which mediate this species' response to environmental variation across its introduced range.

I am fascinated by the fields of molecular biology and bioinformatic analysis, and aim to tie these interests together through the extraction and analysis of large nucleic acid datasets. My project examines the microbiome of deer ticks (Ixodes scapularis) through the use of 16s amplicon analysis of high-throughput sequencing data.

I am intersted in ecology, natural history, evolution, and conservation work. I am investigating evolution of flowering time and resistance to a specialist herbivore in invasive North American populations of purple loosestrife (Lythrum salicaria) and herbivory.

I’m studying the evolution and ecology of purple loosestrife. I’m interested in plant ecology, genetics, and the intersection of biology with math.
