  Across the Northern Hemisphere, chloride concentrations in lakes are increasing from decades of road salt use, imperiling aquatic ecosystems. Elevated chloride concentrations threaten aquatic organisms, and zooplankton are ...

• High sensitivity of freshwater zooplankton to low chloride concentrations is unaltered by nutrient level 

  Greco, Danielle

  Driven by decades of road salt use, freshwater salinization is prevalent across North America. Increasing chloride concentrations threaten freshwater species, and zooplankton are particularly sensitive. In Canada, the ...

• Effects of peripherality and hybridization on range-wide genetic structure of the coastal dune plant Abronia umbellata (Nyctaginaceae) 

  Van Natto, Alyson

  The pattern of genetic variation across a species range may give insight into geographic variation in adaptive capacity and hence, conservation priority. For this reason, determining the factors that may influence range-wide ...

• Understanding sources of variation in advertisement call attributes in spring peepers (Pseudacris crucifer) 

  Chen, Ying

  The mate recognition system is the foundation of biological speciation in frogs and toads. Sexual selection has been suggested to cause male call evolution, population divergence, and ultimately reproductive isolation. It ...

• Long-term response of sockeye salmon (Oncorhynchus nerka) nursery lakes to climate and watershed management activities in British Columbia (Canada) 

  Barouillet, Cecilia

  Sockeye salmon (Oncorhyncus nerka) are a heavily exploited species. Owing to their large geographical distribution and use of both freshwater and oceanic habitats, sockeye salmon are exposed to various stressors at the ...

• Towards a sustainable Arctic fishery: Population genomics of lake whitefish in a hybrid species complex 

  Driver, Hannah

  Genetic variation is an important predictor of population persistence under changing or stressful environmental conditions. Consequently, efforts to preserve genetic variation by identifying genetically distinct populations ...

• Habitat Associations of Coexisting Carrion Beetles (Subfamilies Nicrophorinae and Silphinae) in Southeastern Ontario 

  Burke, Kevin

  The coexistence of closely related species is thought to play an important role in shaping and maintaining local diversity and community organization. However, competition for shared limiting resources can inhibit coexistence ...

• Investigating NLR-mediated immunity and Pseudomonas syringae effector interactions with two MACPF domain proteins in Arabidopsis thaliana. 

  Sementchoukova, Irina

  To disarm plant defenses, successful pathogens secrete an arsenal of diverse virulence factors, termed effectors, into the host cell to shut down key components of the plant immune signaling pathway. To protect against ...

• Arabidopsis Mitogen-Activated Protein Kinase Kinase Kinase Family Members and Their Possible Role in Innate Immunity 

  Siegel, Kristen

  From an early developmental stage, plants are exposed to both beneficial and pathogenic microbes. Upon pathogen detection, receptor complexes on the cell surface can detect conserved microbial molecules, such as bacterial ...

• Investigating Suberin Biosynthesis in Poplar: Candidate Genes and Chemical Composition 

  Rains, Meghan

  For plants, lipid barriers represent a critical adaptation to terrestrial life, providing a first line of defense against biotic and abiotic stressors. Among these lipid barriers, suberized cell walls protect both internal ...

• Bioremediation of arsenic and cadmium in a Populus tremula x Populus alba mutant 

  Weber, Jackie

  The use of plants to remediate contaminated lands is of growing interest to the scientific community because of its ease of implementation, cost effectiveness and ability to stabilize contaminated soils. A novel Populus ...

• Can genomic tools aid conservation of an arctic seabird, the northern fulmar (Fulmarus glacialis)? 

  Colston-Nepali, Lila

  Human activities and climate change threaten Arctic ecosystems. Population genetics and genomics may help conservationists appropriately manage threatened species both by (1) determining the population genetic structure ...

• Assessing the use of Viviparus georgianus snails as a means for biomanipulation of cyanobacterial species Microcystis aeruginosa 

  Kokkinakis, Sofia

  Cyanobacterial blooms can produce toxins which can be fatal to organisms, including humans. Biomanipulation of cyanobacterial harmful algal blooms (CHABs) aims to proactively prevent their formation by maintaining continuous ...

• Using Population Genomics to Disentangle the Evolutionary History and Aid Conservation of the Leach’s Storm-Petrel Species Complex (Hydrobates spp.) 

  Birchard, Katie

  Despite their ability to overcome most geographic barriers to dispersal and to fly long distances, many seabird species exhibit strong population genetic structure. For this project, I quantify population differentiation ...

• Stochastic and adaptive processes affect rapid evolution of two invasive plants in North America 

  Wu, Yihan

  Evolution can occur rapidly on timescales of years to decades. In addition to adaptive responses to natural selection, stochastic processes such as gene flow and genetic drift may influence rapid evolution in many species. ...

• Vocal behaviour of Song and Swamp sparrows upon arrival on shared breeding grounds 

  Bortolotti, Jaimie

  Closely related species interact often, typically competitively, aggressively, and asymmetrically, with a consistent dominance hierarchy among species. Competition for resources appears to be a rate-limiting step in ...

• The maternal effects of haemosporidian infection in red-winged blackbirds 

  Olson, Sarena

  Vector borne diseases present a substantial selective pressure to many animals, as they can impose direct fitness costs and intensify trade-offs between immune function and other life history traits, like reproduction. ...

• Partitioning resources through the seasons: a test of the competitive ability – cold tolerance trade-off hypothesis in seasonally breeding beetles 

  Wettlaufer, Jillian

  Understanding the factors that maintain and constrain biodiversity and species coexistence is a major goal in ecology. Closely related species that use similar resources often differ in their seasonal patterns of activity, ...

• An Exploration of the Intestinal Bacteria of Two Anadromous Arctic Salmonids 

  Element, Geraint

  In teleost fish, the microbiome plays a variety of roles in host physiology and adaptability to different environments. Anadromous fish (migrating to sea after maturation and returning to freshwater to spawn) are reported ...

• Getting One's Ducks in a Row: Conservation Units of Common Eiders (Somateria mollissima) Throughout North America 

  Turner, Russell

  Anthropogenic climate change is resulting in a variety of consequences for ecosystems and biodiversity. Collectively these changes are negatively impacting species survival and are increasing rates of extinction. Species ...
