Glyphosate Research on forest Organisms and Wildlife health
Key Research Objectives
1
Determine the extent and persistence of glyphosate residues in boreal and sub-boreal forests.
2
Evaluate the potential risks to forest biodiversity and ecosystem functions, particularly focusing on soil and plant microbial communities.
3
Assess the impact of glyphosate on the gut microbiome and hormone profiles of wildlife species, including rodents and larger mammals.
4
Investigate the indirect effects of glyphosate on wildlife health, such as changes in behavior, physiology, and reproductive success.
5
Provide scientific evidence to support updates in forestry practices and policy recommendations for glyphosate use.
This research is crucial for Canada, as forests cover a significant portion of the country landmass and play a vital role in its economy, ecology, and cultural heritage. By understanding the impacts of glyphosate on forest ecosystems, we aim to develop evidence-based strategies to minimize negative effects and promote the long-term health and resilience of Canadian forests. Our findings will be shared with partner organizations and the broader community to ensure that the knowledge generated contributes to best management practices.
Research Projects
Glyphosate Residues in Forests
Investigate the extent and persistence of glyphosate residues in Canadian forests, including soil, water, and plant tissues. Dr. Lisa Wood, a plant biologist at UNBC, will lead this aspect, focusing on the factors influencing the distribution and degradation of glyphosate in different forest ecosystems. This involves detailed field sampling and advanced analytical techniques.
Lead Investigator: Dr. Lisa Wood, UNBC
Collaborators: Dr. Jeff Werner, Dr. Susan Murch
Impact on Gut Microbiome
Assess the potential impact of glyphosate exposure on the gut microbiome of wildlife species inhabiting forest ecosystems. Dr. Deanna Gibson at UBCO will utilize advanced genomic techniques, such as 16S rRNA sequencing, to characterize changes in microbial diversity and function in response to glyphosate. This research aims to understand how glyphosate-induced dysbiosis affects wildlife health and behavior.
Lead Investigator: Dr. Deanna Gibson, UBCO
Collaborators: Dr. Jeff Werner, Dr. Susan Murch
Effects on Wildlife Health
Evaluate the potential direct and indirect effects of glyphosate on the health and fitness of wildlife populations in forest ecosystems. Dr. Heather Bryan at UNBC will lead this effort, investigating toxicological risks, behavioral changes, and reproductive outcomes associated with glyphosate exposure through field studies and controlled laboratory experiments.
Lead Investigator: Dr. Heather Bryan, UNBC
Collaborators: Dr. Jeff Werner, Dr. Susan Murch
Ecosystem-Level Consequences
Examine the broader ecological consequences of glyphosate use in forests, including impacts on organismal communities, nutrient cycling, and food web dynamics. Dr. Miranda Hart at UBCO will focus on soil microbial communities and nutrient cycling, while Dr. Dezene Huber at UNBC will assess shifts in arthropod biodiversity. Together, they will evaluate the cascading effects on forest biodiversity and ecosystem functions.
