Working Paper 64, published 2002, was the last of that series. Suzanne Simard (UBC Professor): Stump removal (stumping) is an effective forest management practice used to reduce the mortality of trees affected by fungal pathogen-mediated root diseases such as Armillaria root rot, but its impact on soil microbial community structure has not been ascertained. She is known for her work on how trees interact and communicate using below-ground fungal networks. We determined whether net carbon transfer occurred between conspecific conifer seedlings in the field, and whether soil disturbance or access to mycorrhizal pathways affected transfer.

Large-scale outbreaks of mountain pine beetle (Dendroctonus ponderosae) have killed millions of hectares of lodgepole pine (Pinus contorta) forests throughout North America. Many forest ecosystems are experiencing increased drought stress due to changing patterns of aridity, due to both climate change and human land-use activities. Meet the Team However, little is known of overstory retention levels that best conserve ecosystem services in different regional c... Disturbances are frequent events across the Canadian boreal forest and can affect both below and above ground ecosystem processes. In boreal forests, understory communities are the reservoir of the majority of plant species diversity, influence nutrient cycling, represent habitat and forage for wildlife, and have strong impacts on canopy succession.

The use of trade, firm, or corporation names in this publication is for the information and convenience of the reader. It has been suggested that these networks are ecologically relevant because they may facilitate interplant resource transfer and improve regeneration dynamics.

For tree seedlings in boreal forests, ectomycorrhizal (EM) fungal networks may promote, while root competition may impede establishment. We established two soil disturbances and planted pairs of d... Mycorrhizal fungal networks occur where mycorrhizal fungal mycelia link the roots of multiple plants, including those of different species, sometimes facilitating interplant transfer of carbon, nutrients or water. A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. In June, ecologist Suzanne Simard gave a talk at TED about her 30 years of research into how trees talk to each other. We mapped the belowground distribution of the fungi Rhizopogon vesiculosus and Rhizopogon vinicolor and interior Douglas-fir trees (Pseudotsuga menziesii var. She contributes to this goal by coâ¦ In North America, during the last deglaciation, the distributions of tree taxa varied significantly as regards the rate and direction of their responses for reasons that remain unclear. Forest ecologist Suzanne Simard of The University of British Colombia gave a TED talk in June, during which she detailed research that shows mother trees recognize their kin. The objective of this study was to determine whether interior Douglas-fir (Pseudotsuga menziesii var. Lena Z. in September 2018. Their utilization has gradually increased over the last 20 years, especially in the north. Because tree recruitment and mortality events are generally infrequent, long‐time scales are needed to confirm trends in forests. Soil compaction often limits conifer regeneration on sites degraded by landings and roads, but inadequate understanding of the relationship between compaction and tree growth could lead to inappropriate soil conservation and rehabilitation efforts. Dr. Suzanne Simard is a Professor of Forest Ecology in the Department of Forest and Conservation Sciences at the University of British Columbia. The st... Lodgepole pine (Pinus contorta Dougl. Her work with her students led to the recognition that forests have hub trees, or Mother Trees, which are large, highly connected trees that play an important role in the flow of information and resources in a forest. We also determined the combined influences of inoculum source and distance from trees on the ectomycorrhizal (EM) community of seedlings.

Professor Suzanne Simard, the leader of this project, has been researching the below-ground connections among Douglas-fir trees and other plants for over 30 years. Soil fungi are particularly sensitive to such disturbances; however, the individual response of fungal guilds to different disturbance types is poorly understood. 1. glauca (interior Douglas-fir) both in the context of pure kin stands, in accordance with established plant kin selection and recognition studies, but also in combination with inter and intraspecific neig... 1. Here we examined fixation by Douglas-fir seedlings and transfer to associated ectomycorrhizal fungi, soil microbes, and full-sibling or nonsibling neighbouring... Plants form belowground associations with mycorrhizal fungi in one of the most common symbioses on Earth. Soil nitrogen (N) supply and uptake by regenerating trees is an important ecosystem attribute but difficult to quantify in Suzanne Simardâs research has shown how forests are not just a competitive system but a cooperative once too. However, little is known about how belowground plant traits vary across climate and soil gradients. Mother trees are typically the biggest trees in the forest, and they connect to other trees â¦ 2. Simard, who has spent the last three decades studying the mechanisms that fuel our forests, then went on to demystify the âquiet, cohesive way of the woods,â explaining that treesâin many waysâare just like us. Climate Change and Variability, Suzanne Simard (Ed. Ectomycorrhizal networks are hypothesized to facilitate seedling regeneration under abiotic stress, which could occur via seedling access to a greater volume of soil for nutrient uptake or resource transfer from established plant to seedling. Her 30 years of research in Canadian forests have led to an astounding discovery - trees â¦ Suzanne Simard is an advocate of science communication. The objective of this study was to determine if planting a mixture of tree species following logging retains a higher diversity of ectomycorrhizal fungi than planting a single species. Clearcut logging results in major changes in ectomycorrhizal fungal communities, but whether this results in the loss of key functional traits, such as those associated with nutrient acquisition from soil organic matter, is unknown.

Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self-organization, (4) openness, (5) adaptation, (6) memory, (7) non-linearity, and (8) uncertainty. glauca (Beissn.) "A forest has an amazing ability to communicate and behave like a single organism -- an ecosystem," Suzanne Simard, an ecologist at the University of British Columbia, told CNN. Her research focuses on the complexity and interconnectedness of nature and is guided by her deep connection to the land and her time spent amongst the trees. Her work demonstrated that these complex, symbiotic networks in â¦ The distribution of dry Douglas-fir forests in western North America is expected to shift northward with climate change and disappear from the grassland interface in the southern interior of British Columbia. This research has far-reaching implications for land use management, including the sustainable stewardship of forest ecosystems as climate changes. However, few large-scale generalizations exist for the structure and function of mycorrhizal symbioses, as the nature of this relationship varies from mutualistic to parasitic and is largely context-dependent.

She received her PhD in Forest Sciences from Oregon State University and she worked as a research scientist at the British Columbia Ministry of Forests before joining the faculty at UBC. Different nurse-species offer different degrees of protection, resource competition, and thinning revenues. Processes governing the fixation, partitioning, and mineralization of carbon in soils are under increasing scrutiny as we develop a more comprehensive understanding of global carbon cycling. The principal broadleaves in Interior British Columbia (trembling aspen, paper birch, balsam poplar and black cottonwood) are well distributed across all of the major Interior ecological zones but their occurrence is greatest in the northern areas. Evaluation of resilience is hampered by the short history of logging, lack of long-term experiments and methodological l... Dendrogram of cluster analysis results.
