Stephanie Green (PI)

Canada Research Chair, Aquatic Global Change Ecology & Conservation 


I study the causes and consequences of biodiversity change in aquatic ecosystems, with the goal of developing science-based tools to inform conservation and restoration decision-making under global change. As a scientist, I relish the opportunity to spans spaces: developing projects that bridge concepts and scales of investigation, and fostering relationships between people as they work to affect change. As a result, my interests are broad, ranging from simulation models of predator-prey interactions and food webs, to experiments investigating community assembly and resilience, to coupled social-ecological modeling examining behaviour change. The common theme across my work is advancing ecological theory in service of society. Prior to joining the University of Alberta, I was a Banting Fellow at the Center for Ocean Solutions at Stanford University and a David H. Smith Conservation Research Fellow at Oregon State University.

Postdoctoral Fellows


Natasha Hardy 


My research centres on understanding and maximising ecosystem functionality, ecosystem services and predator-prey trophic relationships in socio-ecological systems. My postdoctoral work focuses on developing frameworks for forecasting marine food web trophodynamics under climate change in the California Current Large Marine Ecosystem in collaboration with Stanford University and NOAA Southwest Fisheries Science Center. Specifically, I am investigating the impacts of climate change on albacore tuna resource use and distributions, an important fishery across the North Pacific. My research spans from planktonic organisms to fish and seals across the Pacific Ocean. I obtained a B.Sc. with Honours with Prof. Maria Byrne, and a Ph.D in 2018 from the University of Sydney, working with Associate Prof. Will Figueira on the ecological interactions of recolonizing populations of fur seals and temperate reef communities in southeastern Australia. I am a settler, growing ally, and advocate for equity and diversity in biological sciences.

Alexandra Davis 


I am a marine spatial ecologist and an advocate for equity and diversity in conservation sciences. I am currently a Liber Ero Postdoctoral Fellow developing conservation strategies for interventions of marine/ aquatic invasive species. I work with multiple partners and management agencies to understand valued resources, develop spatial priorities, and quantify economic costs for managing invasive species. My current study species include Indo-Pacific lionfish in US Caribbean and Tropical Western Atlantic territories, and the European Green Crab in British Colombia and the Salish Sea. 

I currently serve on multiple EDJI committees and am a member of the board of directors for Black Women in Ecology Evolution and Marine Science (BWEEMS). My work within these groups is to elevate marginalized voices in STEM and provide mentorship, professional development, and opportunities for success in the field(s).


Miram Gleiber

OSTRICH_headshotI am a biological oceanographer and plankton/larval fish ecologist interested in marine food web interactions and how they are influenced by environmental variability. I am working with the Green Lab on a project investigating the role of prey traits for marine food web interactions to better understand the effects of climate change on the distribution of Albacore tuna in the Eastern Pacific. I earned my Ph.D (2020) working with Su Sponaugle at Oregon State University, studying the importance of planktonic prey availability and fine-scale distributions for larval tuna and reef fish success in the Florida Current. Prior to this I worked with Dr. Deborah Steinberg studying long-term changes in zooplankton communities in the scope of rapid climate change in the western Antarctic Peninsula during my B.Sc. (2010) and M.Sc. (2014) at The College of William and Mary/Virginia Institute of Marine Science.

Kyle Shanebeck (co-supervised with the Lagrue lab)


I study the interactions between parasites and aquatic mammals. My project is investigating the sub-lethal effects of macro-parasites on river otter and mink in Alberta and British Columbia. Parasites are often considered unimportant in large mammal individual or population health; however, parasites can have complex effects on host energetics (systemic functioning, repair, growth, reproduction). My project asks: do parasitic helminths (worms) influence aquatic mammal individual fitness and population dynamics? Helminths also have complex relationships with pollutants (especially intestinal helminths); and heavy metals are an important threat for aquatic ecosystems in Canada. My project is also monitoring pollutants in both parasite and host tissues: are parasites related to increased or decreased accumulation of pollutants in their host? I was born and raised in southern California; was a research assistant with the Tinker Lab (UCSC) and volunteered for the Monterey Bay Aquarium’s Sea Otter Research and Conservation Program. I completed my MSc in Ecology at the Universität Bremen, Germany; where I studied the demographics and site selection of intestinal Acanthocephalans in Sea Otters and Seals through the Institute for Terrestrial and Aquatic Wildlife Research, University of Veterinary Medicine Hannover, Foundation. I am passionate about marine conservation, parasitology, and cross-discipline collaboration in research!

Cole Brookson 

IMG_5187My research focuses on using computational tools to investigate how ecological networks rewire in the wake of perturbations. I work mainly on food webs, and I am interested in how we can use species traits to better predict and understand how trophic structures change as a result of various types of anthropogenic disturbance, in both broad theoretical contexts as well as specific applied systems. Previous to my work at the University of Alberta, I completed my undergrad in Ecology and Evolutionary Biology at the University of Toronto, where I worked on modelling population responses to pollutants and pathogens in aquatic ecosystems. I am passionate about Open Science and promoting computational literacy and training in the biological sciences.

Alana Krug-MacLeod

Alana profileFor the moment I’m getting my feet wet by filling prey trait data gaps for California Current albacore tuna. I look forward to feeling the ocean spray next summer when I may examine stomach contents of tuna caught by fishers or prey communities in the water column where tuna feed. I completed an interdisciplinary undergraduate honours degree in Environmental Biology at the University of Saskatchewan (USask). A highlight during my undergrad was attending the Korean Arctic Academy and sharing research on the role of the Cumberland Sound indigenous community in protecting Cumberland Sound beluga. Another was volunteering on biodiversity projects at a pre-congress and sharing my Antarctic and Arctic experiences with Students on Ice at the International Union for the Conservation of Nature (IUCN) Congress in Hawaii. My USask lab research included assessing persistent effects on shorebirds of in ovo exposure to contamination and temperature stress, using GIS to identify opportunities for grain farmers to increase ecosystem services, and processing fish bone samples from Viking middens to monitor climate changes.

Courtney Stuart (MSc Winter 2022)

Courtney_GreenWebPhotoI am a marine spatial ecologist studying connectivity across the mangrove-seagrass-reef continuum of the Florida Keys. The main goal of my MSc is to construct species- and stage-specific models of habitat suitability for reef fish with complex life histories, particularly those that involve ontogenetic habitat shifts. These regional scale models are the basis for connectivity analyses and are fundamental to the construction of ecologically-relevant management plans. Prior to joining the Green Lab, I obtained my BS in Marine Vertebrate Biology from the School of Marine and Atmospheric Sciences at Stony Brook University. My senior honors thesis examined the patterns, rates, and socio-ecological consequences of tooth replacement in fishes of the Peruvian Amazon. I am passionate about diversity in the scientific community, science communication and mentorship, and #WomenInGIS.



Victoria Van Mierlo (MSc Fall 2021)

IMG_4538 edit1

I study the interactions of invasive Northern Crayfish (Faxionis virilis) with native freshwater fish communities and effects on food web dynamics in Alberta. As a lover of nature and native Southern Ontarian, I am especially interested in the extensive negative impacts that invasive species have on native ecosystems. I received my BSc in Honors Biology at McMaster University, where my thesis work was focused on the efficacy of entomopathogenic fungi to weaken the immune system of the invasive marmorated stink bug (Halyomorpha halys). Additionally, I participated in coral reef species assemblage surveys after the introduction of invasive lionfish at the Cape Eleuthera Institute. Through my MSc work, I hope to provide information to managers that improves invasive species management at the watershed level. I am passionate about sustainability, interdisciplinary solutions, and inclusion in science and research!



Aneri Garg (MSc Spring 2021)

I studied the effect of restoration activities on community dynamics and ecosystem assemblage using coral reefs as a model ecosystem. My interest in applied science is to create tools for conservation practitioners, while working with diverse collaborators to create sustainable conservation and restoration solutions. Prior to the University of Alberta, I completed research internships at the Coral Health and Disease Lab at Mote Mote Marine Laboratories in Sarasota, FL, and at Cape Eleuthera Institute in the Bahamas. My undergraduate research at the Marine Macroecology and Biogeochemistry Lab at Mount Allison University focused on quantifying major macromolecular pools in a dominant Arctic phytoplankton strain. I am passionate about diversity and inclusion in science, science communication, and tiny but vital organisms (ie corals, algae, and lichen!)


Noelle Helder (MSc Spring 2021)


I studied how species assemblages on restored coral reefs in the Florida Keys affect nutrient recycling. Stemming from a strong interest in natural resource management at all levels, I aim to use applied sciences to better understand changes in economically valuable ecosystems and develop tools to influence better management decisions. Prior to my MSc, I spent time working with the School for Field Studies in the Turks and Caicos Islands and at the Central Caribbean Marine Institute in the Cayman Islands, developing an interest in engaging stakeholders starting at the community level in resource management decisions. As an avid outdoor enthusiast and guide, I am also passionate about experience-based education, expedition-based research, and empowering underrepresented communities to engage in scientific endeavors.

My research uses SCUBA surveys, photogrammetry, stable isotopes, and spatially explicit modelling to understand feedbacks between reef fish communities and their habitat on coral reefs in the Florida Keys National Marine Sanctuary. We work closely with local partners including NOAA and the Coral Restoration Foundation. Previously, I have worked throughout the Caribbean on projects relating to Marine Protected Areas, coral reef conservation, and science communication. I also co-lead the Education and Outreach Committee with the International Coral Reef Society Student Chapter.

I studied aquatic invasive species with a social-ecological focus on the roles  community engagement play in invasion success and management. I take an interdisciplinary approach to research and collaboration,  with the goal of engaging with the public, government, and industry to work towards more sustainable communities. After completing a degree in marine biology with a minor in psychology at Dalhousie University I gained experience in scientific outreach, education, and research, and now continue my journey at the University of Alberta.





Iris George (Undergraduate Researcher 2019-21)


I completed my undergraduate degree in Ecology, Evolution, and Environmental Biology at the University of Alberta and hope to continue my research career in graduate school. My research projects in the lab focused on two areas: 1) the diets of albacore tuna in the California Current Large Marine Ecosystem, and 2) the efficacy of survey techniques for Caribbean coral reef fish community monitoring.






Zachary Roote (Undergraduate Researcher 2019-21)


I completed my undergraduate degree in Conservation Biology degree at the University of Alberta. Through an NSERC USRA in Summer 2019 and Biol 499 in 2020-21, I tested the desktop ecologist waters, working with Dr. Natasha Hardy to identify knowledge gaps and assess variability in the prey quality literature for species found in the diets of albacore tuna.





Caitlin Morganson (Undergraduate Researcher 2020-21)

Caitlin Morganson

I graduated with a degree in Animal Biology degree program at the University of Alberta. Through a Biol 499 in 2020-21, I examined trait-based foraging behaviours of albacore tuna in the California Current System. Specifically, I worked in collaboration with Dr. Natasha Hardy and the Green the lab at UAlberta, and researchers at NOAA and Stanford University, to collect and analyse a suite of traits of available and used albacore prey data using multivariate statistics. 




Cindy Matuch (Undergraduate Researcher 2019-20)


I am a NOAA Center for Coastal and Marine Ecosystems Undergraduate Scholar at the California State University of Monterey Bay and currently working towards a Marine Science degree with a minor in Statistics. I studied the foraging traits of albacore tuna with Dr. Natasha Hardy to help forecast what their diet might me once this species migrates due to climate change.




Daniel Field (Undergraduate Researcher 2019-20)


I’m a biological sciences major interested in invertebrate biology. Through a UAlberta Undergraduate Research Award and Biol 298, my project focused on automating processes in ArcMap to collect terrain data from 3D models of reef ecosystems. I also used said data to take a rudimentary look at how terrain rugosity affects benthic organism diversity across natural and restored reef sites.
