Tallgrass restoration – Ontario
Two years after planting, community assembly at our tallgrass prairie research facility on the RARE conservation preserve is well under-way.
MSc position 2012-2014: Metacommunity Dynamics and Community Assembly
A fully funded MSc position is now available in our research group, starting September 2012. We seek a student with broad interests in community ecology, food webs dynamics, or insect or plant ecology. The student’s work will be a part of a larger scale experimental project, which aims to understand the impact of environmental and spatial constrains on the community assembly and succession of grassland food webs (producers, herbivores, predators, pollinators). There is room for creativity, and as such the student will be encouraged to build their own project depending on interests and background. Please send a copy of your C.V., unofficial transcript, and a short statement on your research interests to amacdo02@uoguelph.ca Position Filled – thanks to all applicants.

“As sheep advance, flowers, vegetation, grass, soil, plenty, and poetry vanish” – John Muir (1893)
Grasslands evolved with grazing and fire, yet the influences of both processes have fundamentally changed over the last 150+ years. Some systems are overgrazed, while others lack grazing altogether. The effects of fire suppression range from tree infilling to the increased occurrence of periodic catastrophic burns due to high fuel loads . We are exploring the implications of these changes for grassland structure and function, using a series of long-term fire and herbivory experiments on Vancouver Island and the southern Gulf islands of British Columbia. This includes testing the relative impacts of native and introduced grazers on diversity and community assembly, and how burning and grazing combine to influence the demographics of disturbance-dependent plant species. To Muir’s horror (we assume), this includes grazing trials with sheep… (managed by Irvin Banman of the Nature Conservancy of Canada).
Welcoming our newest lab member…
One of our research interests is how metacommunity dynamics underlie the assembly and functioning of species-rich systems. We are excited to welcome a shiny new tractor, which will help us initiate the assembly of oak savanna communities in sites currently occupied by old-field on Vancouver Island. Funding support provided by CFI-LOF, with significant in-kind contributions from the Nature Conservancy of Canada.
New Research on Tumbo Island, Gulf Islands National Park 2010
We will be starting a long-term collaborative research experiment this spring on Tumbo Island in the Gulf Islands National Park Reserve(below, in the shadow of Mt. Baker). This project will be run in association with Mark Vellend’s lab at the University of British Columbia and Marlow Pellatt at Parks Canada. Graduate student opportunities for highly qualified candidates (PhD) may soon be available; please contact us if you are interested.
Spring 2010
Visit by Trevor Herriot
Our lab will be welcoming award-winning author Trevor Herriot to Guelph on Monday March 15th 2010, for a reading and slide-show presentation at The Bookshelf. Thanks to the School of Environmental Sciences for helping to sponsor Trevor’s visit.
PhD position 2011-2014: Metacommunity Dynamics and Community Assembly
Metacommunity dynamics should play a critical role in the assembly of plant communities, based on the potential influences of dispersal, source-sink dynamics, stochastic factors, and trait-based species sorting over time. Using combined experimental, demographic, and statistical approaches, we plan to isolate the relative influence of these factors with a unique large-scale (40 acre), long-term assembly experiment in tallgrass prairie in southern Ontario. We seek a highly-motivated PhD candidate with a strong theoretical and field-based empirical background to use this project as the basis for their dissertation research, starting late 2010 or 2011. The candidate must have experience preparing and, ideally, submitting at least one manuscript to a peer-reviewed ecology-based journal, be capable of working both independently and collaboratively, and be interested in connections between theoretical and applied issues in conservation biology. The direction and scope of the student’s research will be self-determined based on the candidate’s interests and background. Possible topics include (but are not limited to): whether population, community, and ecosystem-level responses to metacommunity processes are synergistically linked or unfold independently during assembly; whether producer, herbivore, and predator responses are synergistically linked or unfold independently during assembly; the degree to which the relative strengths of metacommunity processes vary at different stages of assembly; whether the size, shape, and connectivity of metacommunity patches influence their stability and functioning; and how extrinsic influences associated with climate change, fire, and herbivory deflect or intensify assembly trajectories. The successful student will be remunerated with a combination of fellowships, research or teaching assistantships, with funding guaranteed for three years. Please submit a letter of interest and CV including undergrad and MSc grades to Dr. Andrew MacDougall, Department of Integrative Biology.

PhD position: Spatial Processes in Deciduous Forest Understories
Drs. Karl Cottenie and Andrew MacDougall
Department of Integrative Biology
University of Guelph
Understory plant communities of the eastern deciduous forest of North America are extensively studied but remain poorly understood due to the complexity of limiting processes that affect their member species. Emerging evidence points to the importance of spatial distance and environmental heterogeneity, but how these factors vary by spatial scale, site history, phylogenetic relatedness, latitude, and isolation distance is unclear. We seek a highly motivated PhD student to examine these issues using trait-based, statistical, and experimental approaches in deciduous forest understories of southern Ontario, Canada. These understories are diversity hotspots in Canada, containing large numbers of rare and endangered plants. Their declines are well-described but the causal mechanisms are elusive, giving this study theoretical and applied significance. Interested applicants should ideally have an MSc in ecology, biogeography, or statistical biology, with field experience including experimental approaches and plant identification. The successful student will be remunerated with a combination of fellowships, research or teaching assistantships, with funding guaranteed for three years. POSITION FILLED – THANKS TO ALL APPLICANTS

The candidate must have experience preparing and, ideally, submitting at least one manuscript to a peer-reviewed ecology-based journal, be capable of working both independently and collaboratively, and be interested in connections between theoretical and applied issues in conservation biology. The direction and scope of the student’s research will be self-determined based on the candidate’s interests and background. Possible topics include (but are not limited to): whether population, community, and ecosystem-level responses to metacommunity processes are synergistically linked or unfold independently during assembly; whether producer, herbivore, and predator responses are synergistically linked or unfold independently during assembly; the degree to which the relative strengths of metacommunity processes vary at different stages of assembly; whether the size, shape, and connectivity of metacommunity patches influence their stability and functioning; and how extrinsic influences associated with climate change, fire, and herbivory deflect or intensify assembly trajectories. The successful student will be remunerated with a combination of fellowships, research or teaching assistantships, with funding guaranteed for three years. Please submit a letter of interest and CV including undergrad and MSc grades to Dr. Andrew MacDougall, Department of Integrative Biology.
- Congratulations to Mariana Chiuffo (Ph. D candidate with Dr. Jose Hierro, Universidad Nacional de La Pampa, Argentina), who has been awarded a research grant from the Emerging Leaders in the Americas (ELAP) program. Funded by the Department of Foreign Affairs and International Trade (Canada), this grant will allow Mariana to join our lab in 2010. Her work on invasion biogeography, plant competition, and neutral-based priority effects will be centered in Las Pampas grasslands of central Argentina and climatically analagous grasslands in Canada.

PhD position: Spatial Processes in Deciduous Forest Understories
Drs. Karl Cottenie and Andrew MacDougall
Department of Integrative Biology
University of Guelph
Understory plant communities of the eastern deciduous forest of North America are extensively studied but remain poorly understood due to the complexity of limiting processes that affect their member species. Emerging evidence points to the importance of spatial distance and environmental heterogeneity, but how these factors vary by spatial scale, site history, phylogenetic relatedness, latitude, and isolation distance is unclear. We seek a highly motivated PhD student to examine these issues using trait-based, statistical, and experimental approaches in deciduous forest understories of southern Ontario, Canada. These understories are diversity hotspots in Canada, containing large numbers of rare and endangered plants. Their declines are well-described but the causal mechanisms are elusive, giving this study theoretical and applied significance. Interested applicants should ideally have an MSc in ecology, biogeography, or statistical biology, with field experience including experimental approaches and plant identification. The successful student will be remunerated with a combination of fellowships, research or teaching assistantships, with funding guaranteed for three years. POSITION FILLED – THANKS TO ALL APPLICANTS
