Large-scale outbreaks of mountain pine beetle (Dendroctonus ponderosae) have killed millions of hectares of lodgepole pine (Pinus contorta) forests throughout North America. Aboveground and belowground factors play important roles, and determining their relative contribution to tree success will greatly assist in refining predictive models and forestry strategies in a changing climate. Such understanding has become increasingly important in light of observed changes i... Forests are complex adaptive systems in which properties at higher levels emerge from localized networks of many entities interacting at lower levels, allowing the development of multiple ecological pathways and processes. var. Suzanne Simard is a Professor of Forest Ecology in the Department of Forest and Conservation Sciences at the University of British Columbia, Canada. The foliar attributes of N concentration (N%) and N per unit area (Na) may help characterize the influence of soil nutrition, but ideally the relationship between soils and f...

However, little is known about how belowground plant traits vary across climate and soil gradients. has been extensively planted throughout interior British Columbia, and as a result may be particularly susceptible to climate-induced changes in the range and severity of common damaging agents. We tested the role of networks in interactions betw... Mycorrhizal networks, defined as a common mycorrhizal mycelium linking the roots of at least two plants, occur in all major terrestrial ecosystems.

Dendroctonus ponderosae has killed millions of Pinus contorta in western North America with subsequent effects on stand conditions, including changes in light intensity, needle deposition, and the composition of fungal community mutualists, namely ectomycorrhizal fungi. The importance of mycorrhizal network (MN)-mediated colonization under field conditions between trees and seedlings was investigated. 2. Furthermore, little is known about the importance of resource partitioning in structuring ectomycorrhizal fungal c... Background: Carbon can move below ground between ectomycorrhizal plants, but the relative importance of transfer through common mycorrhizal networks (CMNs) or soil pathways remains unclear. Thus, disruption to EM fungal networks may decrease seedling establishment owing to the loss of positive interactions among neighbors. Her 30 years of research in Canadian forests have led to an astounding discovery - trees â¦ We used annual basal area increment of trees and previously descr... Temperate forests provide crucial ecosystems services as living sinks for atmospheric carbon (C) and repositories of biodiversity. The rapid and widespread death of lodgepole pine will likely have cascading effects on biodiversity. 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. Applying harvesting at intensities that minimize losses offers one means for mitigating global change. Separating edaphic impacts on tree distributions from those of climate and geography is notoriously difficult. Trees often exist in a complex ecological system with many biological interactions. Given the potential for climate change to affect our valuati... 1. Franco var. This damage is resulting from warmer and drier summers associated with climate change.

Toona ciliata Roem. At UBC, she initiated with colleges Dr. Julia Dordel and Dr. Maja Krzic the Communication of Science Program TerreWEB, which has been training graduate students to become better communicators of their research since 2011. A walk amongst the trees is rejuvenating, nourishing and healing, yet a forest is so much more than an amazing collection of trees. The inoculum potential and diversity of the ectomycorrhizal fungal community usually decrease on a site following logging. ex Loud.) 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. 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. glauca) seedling establishment is affected by the presence of an ectomycorrhizal network (MN), and whether this varies by regional climate, seed provenance and seedling life history. We review this assumption using research examining interactions between paper birch (Betula papyrifera Marsh.) The objective of this study was to determine whether interior Douglas-fir (Pseudotsuga menziesii var. I am a PhD candidate under the direction of Dr. Suzanne Simard, and my research will mainly focus on root system behaviour along an altitudinal gradient. 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. 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. Many forest ecosystems are experiencing increased drought stress due to changing patterns of aridity, due to both climate change and human land-use activities. (XLSX). She is an advocate for science communication and empowers people with science-based knowledge to help manage and heal forests from human impacts, including climate change. 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.

Mycorrhizal networks (MNs) are fungal hyphae that connect roots of at least two plants. We quantified stocking status and damage incidence in sixty-six 15- to 30-year-old lodgepole pine plantations that had previously been declared free-growing in the southern interior of British Columbia. Sorry, you need to be a researcher to join ResearchGate. These tree behaviors have cognitive qualities, including capabilities in perception, learning, and me... Tree range shifts during geohistorical global change events provide a useful real‐world model for how future changes in forest biomes may proceed. Wildfire severity in forests is projected to increase with warming and drying conditions associated with climate change. In a common glasshouse,... Extensive regions of interior Douglas-fir (Pseudotsuga menziesii var. Because tree recruitment and mortality events are generally infrequent, long‐time scales are needed to confirm trends in forests. "A forest is much more than what you see," says ecologist Suzanne Simard. In this study, lodgepole pine (Pinus contorta Dougl. 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. It is unknown whether these changes in stand conditions will have cascading con...

Tree plantations are commonly used to restore abandoned agricultural fields with varying degrees of success. Our objective was to determine the impact of wildfire and clearcutting severity on the ectomycorrhizal fungal (EMF) community of Douglas-fir seedlings in the dry forests of interior British Columbia, Canada. Here we examine kin interactions of Pseudotsuga menziesii var. Here, we profiled soil fungal communities in lodgepole pine...

Ectomycorrhizal (EM) networks are hypothesized to facilitate regeneration under abiotic stress. Her research is motivated by her desire for protecting our fundamental right to a clean and healthy environment. Simardâs research on these underground communication pathways and their âmother treeâ hubs has revolutionized our understanding of plant communities and informs popular literature, including Peter Wohllebenâs best-selling book, âThe Secret Life of Trees,â and Richard Powersâ Pulitzer Prizeâwinning novel, âThe Overstory.â Suzanne Simard conducts scientific research on what we cannot easily see â specifically the synergies and complexities of our natural world and the development of sustainable land stewardship practices that both conserve and protect the environment. This basic understanding is also providing a foundation for predicting and managing the consequences of climate change on ecosystems, including their resilience to disturbance, biotic d... Commercial nursery practices usually fail to promote mycorrhization of interior Douglas-fir [Pseudotsuga menziesii (Mirb.) 115,000 people, the majority of whom are First Nations, Inuit and Métis. 1.
