Haley Branch

haley.branch at botany.ubc.ca
PhD student

Haley completed her MSc at the University of Toronto, where she studied the effects of heat stress on reproductive development in Trianthema portulacastrum, a desert plant. She is interested in how plant communities will respond to changes in environmental stresses due to climate change. She is particularly interested in the role plant physiology plays in determining community assemblage under novel stresses. For her PhD, she is studying the physiological and morphological responses of Erythranthe cardinalis after generations of exposure to the California drought.

Rassim Khelifa

Postdoc Fellow

My general interest lies at the interface of environmental sciences and evolutionary biology and involves life history plasticity, dispersal ecology, sexual selection, and conservation biology. My current research focuses on changes in the distribution range of odonates across latitude and elevation in Europe. My main questions are: what drives the variability in the range shift of species? How can we predict future range dynamics of communities? How species respond to climate change across different geographic gradients.
My previous postdoc research, which was conducted with Prof. Stefan Lüpold at UZH, focuses on understanding whether female choice depends on intrinsic male quality or male-female genetic compatibility. I am also interested in how toxins (pesticides) change female choice, male performance, genetic compatibility and ultimately sexual selection. To this end, I use laboratory experiments on Drosophila melanogaster. With my team consisting of postdocs and PhDs in Algeria, we carry out regular surveys to characterize the odonatological and avian fauna of the country and identify the threats that endanger the persistence of species. We also use citizen science and take into account the cultural aspect of society to effectively come up with solutions to establish effective conservation plans.

Chris Kopp

ckopp at biodiversity.ubc.ca
Teaching and Research Postdoc

Chris is interested in how plant species in mountain environments have responded to recent climate change and how they will respond to future climate shifts. This interest includes understanding direct responses to climate as well as outcomes of novel species interactions. To test these responses he employs techniques such as resurveys, repeat photography, species removal and warming experiments.

Mackenzie Urquhart-Cronish

murquhart at biodiversity.ubc.ca
PhD student

Mackenzie is interested in the demographic causes and genetic consequences of range expansion. Specifically, she is interested in the relationship between the speed of spread and the genetic load of leading-edge populations during range expansion. She will be empirically testing theoretical predictions about whether genetic load decreases fitness at leading edges of expanding populations using a combination of field-based and genomic methods with natural populations of monkeyflower species (Erythranthe tilingii and E. lewisii).

Takuji Usui

usuitakuji at gmail.com
PhD student

Takuji is interested in the eco-evolutionary processes that govern changes to species distributions. In response to environmental change, he is interested in the role of: (1) selective and stochastic evolutionary processes; and (2) species interactions in determining population dynamics at both the leading edge (e.g. range expansion) and trailing edge (e.g. evolutionary rescue) of the species range. In addition to these disequilibrial dynamics, he is further interested in the demographic and genetic processes that shape equilibrial (i.e. fitness and niche limited) range limits. To explore these themes, Takuji is currently setting up a novel, lab replicated species ‘range’ using multiple coexisting species of duckweed. Through utilizing experimental evolution, he will run lab experiments to study the effects of evolution on range dynamics in real time.

Megan Bontrager

mgbontrager at ucdavis.edu
PhD 2012-2018
Currently: Postdoc, UC Davis

Megan began her PhD in the Angert Lab in September 2012. She is
interested in factors shaping species distributions and the adaptation of species to marginal habitats. She is particularly interested in the genetic and demographic contributions of pollinators to processes that limit species' ranges. During her thesis, she investigated how gene flow and genetic structure across heterogeneous landscapes contribute to shaping ranges. She pursued these research directions using the annual wildflower Clarkia pulchella as a focal species. Her thesis work utilized field experiments in natural populations, common gardens at the range edge, and population genomics.

Rachel Germain

rgermain at zoology.ubc.ca
Biodiversity Postdoc, 2016-2018
Currently: Assistant Professor, University of British Columbia

Rachel studies historical contingencies in ecology--how events that have occurred few, tens, or tens of millions of years in the past can have persistent effects on present-day ecological dynamics. Her current research tests how species' histories of competitive interactions have driven evolutionary divergence through the phenomenon of character displacement (CD). She aims to reinvigorate CD research by using methods that (i) have more power to detect CD, and provide (ii) a clear mechanistic understanding of how CD manifests, (iii) its strength relative to other evolutionary drivers, and (iv) its consequences for competitive outcomes among competing species.

PhD 2012-2017
Currently: Postdoc, Chicago Field Museum

Qin's research interests are generally in macroecology, evolution, and biogeography. Qin received her B.Sc in Biology and M.Sc in Ecology from Beijing Normal University where she studied wildlife monitoring (e.g.
infrared-camera trap for Amur tiger and other mammals) in boreal forest in northeastern China, as well as species distribution modeling for plants. Qin's thesis work focussed on niche divergence across the Mimulus genus, considering phylogenetic relatedness, evolutionary processes, and
geographic distribution attributes, using a combination of techniques (modeling, field work, and greenhouse experiments).

Chris Muir

cdmuir at hawaii.edu
Biodiversity Postdoc, 2013-2016
Currently: Assistant Professor, University of Hawai’i Mānoa

Chris is an evolutionary biologist who uses ecophysiology as a way to connect fitness tradeoffs to local adaptation and speciation. The goal of Chris's research is to renew and advance an evolutionary physiology synthesis in plants using comparative methods, genetics, field studies, and theory.

Rachel Wilson

rachelnora.wilson at gmail.com
MSc student, 2014-2016
Currently: Ecology instructor, UBC

Rachel backpacked all over the North Cascades to resurvey legacy vegetation plots and assess changes in species' distributions along elevation gradients. She found that most species have not shifted their ranges over the past 30-40 years, despite substantial increases in winter temperatures. However, many species decreased in abundance within their historic ranges.

Devin Gamble

Honors thesis, 2017

Devin looked at mating system variation among populations across the range of a mixed-mating wildflower (Clarkia pulchella). His work examined why populations differ in their reproductive strategy and which climatic factors drive selection for self or cross-pollination.

 

Anna Hargreaves

alhargreaves at gmail.com
Biodiversity Postdoc Fellow, 2014-2016
Currently: Assistant Professor, McGill University

Anna is interested in the ecology and evolution of species interactions, species’ range limits, and their interface. Her research uses field experiments, theoretical and empirical syntheses, and simulation models to explore the evolutionary ecology of range limits and biotic interactions, especially pollination. She focuses on the relative importance of the abiotic environment, biotic interactions, and dispersal in limiting ranges, and how variation in fitness, selection and adaptation towards range limits might impact future evolution of niche breadth and dispersal.

Anna Mária Csergő

anna.maria.csergo at gmail.com
Research Associate, University of British Columbia, 2012-2013
Currently: Marie Curie Postdoctoral Fellow, University of Dublin

Anna asks: How are population dynamics are affected by environmental variability? What are the mechanisms linking traits, environment and biotic interactions to spatial population dynamics? Can the variation in
demographic rates be predicted from the position of populations
within the geographic range and within ecological niche space? Which demographic rates may signal persistent or shifting geographic ranges? She answers these questions by linking range-wide variation in population dynamics to spatially explicit predictions of habitat suitability.
