MSc, Ecology (2017 - )

Supervisors: Dr. James Cahill, Jr., Dr. Mark Boyce

 

Grassland soil organic carbon, greenhouse gas emissions, water infiltration and biodiversity under grazing management practices in Canadian grasslands

Grasslands are key providers of global biodiversity; food security through livestock production; and climate change mitigation through soil carbon storage. However, the relationship between grassland management, biodiversity, and soil carbon sequestration is poorly understood. As part of a team investigating how soil carbon dynamics relate to rangeland management, Jessica is investigating plant community characteristics. From 2017-2019 plant community metrics including biodiversity will be collected from private ranches across western Canada. Results will be used to inform governmental ecological goods and services policy.

Jeff Hogberg

PhD (2017 - )

Supervisor: Dr. Cameron Carlyle

 

 Response of soil microbial ecosystems under different grazing management systems

Adaptive multi-paddock (AMP) grazing emphasizes a high stocking rate in a limited area for a brief period, with appropriately long rest time to allow the plant community to recover. More conventional continuous grazing systems generally aren’t as acutely intensive, but may encourage patterns of usage that may lead to ecosystem shifts over time. Jeff’s research is part of a larger project examining overall differences in impacts to pasture ecosystems under AMP and continuous grazing systems. Jeff’s analysis of differences in the soil microbial ecology will be linked with shifts in plant community, soil carbon storage, greenhouse gas emission, and other ecosystem aspects. Jeff hopes that this project will help create a more comprehensive understanding of the impact of the different grazing systems and help provide a stronger case as to which system is better ecologically and economically.

MSc (2016 - )

Supervisors:  Dr. Scott Nielsen, Dr. Edward Bork

 

Breeding songbird responses to roads and powerlines in the grasslands of Southeastern Alberta

Linear disturbances in grassland systems, including powerlines, roads, and pipelines, have led to fragmented landscapes, soil degradation, and declines in sensitive species. Grassland birds, in particular, have undergone steep declines in populations due to the loss and degradation of grassland habitat. The construction of a major new transmission line in Southeastern Alberta in 2014 provides a unique opportunity to determine the direct effects of powerline construction on songbird species by comparing baseline pre-construction data from 2012 and 2013 to data from 2016 following transmission line development. Caroline is interested in determining how powerline construction affects species richness and species-specific responses. Her analyses looks at how community structure changes with disturbance and makes comparisons between years to evaluate the direct effect of powerline development in grassland habitats on songbirds, and what might be done to mitigate the effects of future transmission line developments on grassland songbirds.

Angela Phung

 MSc (2014 – 2017)

Supervisors: Dr. Cameron Carlyle, Dr. Jessamyn Manson

 

Understanding effects of herbivory on plant-pollinator interactions

Herbivory can lead to trade-offs between plant growth and reproduction, which can be mediated by the timing and intensity of defoliation. Angela studied how the timing and intensity of grazing affect the growth and reproduction of cicer milkvetch, a large flowering plant introduced from Europe that is commonly used in pastures. Secondly, Angela looked at how grazing affects floral resources available to pollinators, pollinator visitation, and subsequently plant reproduction. Studying these interactions is important considering declines in pollinator diversity and abundance, which may affect native plant populations. Pollinators also help maintain flowering forage plants that support livestock in rangelands. Angela is also interested in the how the density of cicer milkvetch may affect pollination of native plants. Angela defended her thesis January 2017.

MSc candidate and Research Assistant

Supervisors: Dr. Ellen Macdonald, Dr. Fiona Schmiegelow, Dr. Edward Bork

 

Can Wet Areas Mapping (WAM) be used to predict invasive species in Dry Mixedgrass Prairie?

Lori is involved in two separate grassland research projects. In the Dry Mixed Grass Prairie (DMG) of southern Alberta (on the Mattheis Research Ranch and in Dinosaur Provincial Park), she is researching whether Wet Areas Mapping (a LiDar based, digital elevation model of depth to water) can be used as a landscape-level tool for predicting patterns of invasion of non-native vascular plant species in grassland ecosystems of Alberta. Her thesis project, on the other hand, focuses on Yukon grasslands and the impact of a reintroduced wood bison herd on plant diversity. These northern grasslands are very different from prairie grasslands in that they occur in small pockets on south-facing hillsides within the boreal forest, yet they share many species and characteristics with the DMG prairie of Alberta. Both projects reflect her interest in unique and rare plant communities, rare species and the conservation of diversity. Together they encompass her love of her northern home, and of the spare, but rich, Dry Mixed Grass Prairie.

Ellen_Macdonald

Dr. Ellen Macdonald

 

Dr. Macdonald is a Professor and Chair of the Department of Renewable Resources at the University of Alberta. She obtained her BSc in Environmental Biology and PhD in Plant Ecology from the University of Calgary. She is interested in factors driving plant community composition and diversity, including the impacts of natural and anthropogenic disturbance. While for the past 25+ years most of her research has focused on the ecology of northern forests, she has also worked in grasslands and in alpine and arctic tundra. She strives to conduct research through which she can apply basic principles of forest ecology to approaches for wise management and conservation of ecosystems.

  

Dr. Macdonald and Lori Schroeder are conducting research to test whether Wet Areas Mapping (a LiDar based, digital elevation model that produces a metric of relative wetness) can predict invasive species occurrence, and whether it can be used to identify rare, and particularly vulnerable, communities in the dry mixed grass prairie (DMG). Invasive species have been identified as one of the most serious threats to ecosystem health and to the conservation of biodiversity and endangered species, particularly in light of a warming climate. The rate of invasion of non-native species into ecosystems, however, often exceeds our ability to document their presence and, thus, protect vulnerable ecosystems. Wet Areas Mapping has been proposed as a landscape-level tool for predicting patterns of invasion of non-native vascular plant species in grassland ecosystems of Alberta. Simultaneously, they are examining impacts of disturbance on invasive species occurrence - including grazing and disturbance associated with pipelines, roads, wellsites and transmission corridors.

Dr. M. Anne Naeth


Dr. Anne Naeth is a Professor of Land Reclamation and Restoration Ecology in the Department of Renewable Resources and Associate Dean of Research and Graduate Studies at the University of Alberta. She is also Director of the Land Reclamation International Graduate School (LRIGS). Dr. Naeth’s expertise is in land reclamation and restoration ecology. In Canada, approximately 70 % of native grasslands and 83 % of foothills fescue grasslands have been lost due to agriculture, human disturbances, woody species encroachment, fire suppression, plains bison extirpation and invasion by non-native species. Disturbed grasslands require enhancement and restoration to maintain landscape diversity and protect remaining grasslands. Dr. Naeth has 30 years of research experience in grassland ecosystems where her research has investigated impacts of grazing and oil and gas activities on soil properties and plant community development, management of non native plant species, and development of effective revegetation methods. She has worked on grasslands in Alberta and Saskatchewan including foothills and plains rough fescue prairie, mixed grass prairie, montane and aspen parkland meadows. Her research program is both applied and theoretical and focuses on plant-soil-water relationships, understanding and defining processes inherent in these relationships, their effects on ecosystem structure and function, their response to disturbance and their role in reclamation after disturbance. Recent rangeland research focuses on methods to enhance and restore silver sagebrush (Artemisia cana) steppe in Grasslands National Park as habitat for the endangered greater sage grouse and methods to overcome low seed germination and seedling establishment.
