Interior Douglas-fir, an economically and culturally valuable conifer species, has recently had inconsistent regeneration success in the dry climatic regions of its distribution due to high summer soil surface temperatures, drought and growing season frost. Overall, survival was greatest for these seedlings relative to those from the wet or dry provenances, but decreased with summer heat:moisture index more rapidly. Students’ knowledge of mycorrhizal ecology increased after playing Shroomroot, and engagement with mycorrhizal content tended to increase after gameplay. Suzanne Simard et sa fille devant le centre de recherche en foresterie de l'UBC. Mycorrhization greatly influenced productivity of western redcedar seedlings; without mycorrhizal inoculum, redcedar did not achieve its full growth potential in HA clearcuts. Climate Change and Variability, Suzanne Simard (Ed. CORONAVIRUS (COVID-19): please review UBC’s general information and FAQs and G+PS's graduate student-specific information. Suzanne Simard is a world-leading scientist who has developed a strong, well-recognized research program at UBC. Furthermore, molecular characterization of Armillaria using translation elongation factor-1 alpha (tef-1) and ITS revealed the occurrence of A. gallica, reported for the first time at this site. With colleagues at UBC, she launched TerreWEB, an innovative graduate training program that integrates global change science, social science and communications research.

Kin recognition was also weakly evident in the field, where it was expressed as differential survivorship among kin versus non-kin seedlings. Molecules potentially involved in defense signaling were identified using liquid chromatography coupled with mass spectroscopy. Suzanne Simard. MN features were contrasted between plots with xeric versus mesic soil moisture regimes as a proxy for changes in site water stress anticipated with climate change. Assistant professor. We used DNA metabarcoding targeting the fungal internal transcribed spacer (ITS) marker and the bacterial 16S rRNA gene to decipher the microbiomes. Furthermore, the network appears to act a conduit for information chemicals, where defense chemicals are transferred in response to herbivory or pathogen attack. At UBC, she has a vibrant research program, a teaching program focused on forest ecology and complexity science, and she is a strong contributor to the forestry profession in Canada. However, the preference of western hemlock for CWD is still not completely understood. Results indicate the complexity of these systems, and further work is needed to better characterize defense signal transfer via ectomycorrhizal networks. Few studies have investigated belowground dynamics related to western hemlock growing on decayed wood, specifically ectomycorrhizal (EM) associations and the potential access to a mycorrhizal network (MN). Though diversity was similar, ectomycorrhizal and saprophytic fungal community composition significantly differed between CH and HA forests; arbuscular mycorrhizae were widespread in CH forests, but rare in HA forests. The SEM indicated that mean annual precipitation (MAP) negatively influenced fire severity; mean annual temperature (MAT) positively influenced fire severity and soil nutrients; and MAP and MAT directly and/or indirectly influenced most PFTs. Seeds of interior Douglas-fir germinate after mixed severity disturbances, but their survival appears to depend on the size of disturbance gaps, environmental resources and conditions, and colonization by mycorrhizal fungal symbionts. 2424 Main Mall British Columbia’s Interior Douglas fir forests are predicted to move north, following the climate they thrive in. Suzanne Simard (UBC) is a leading world expert in forest ecology … “Dr. Overall, we conclude that stumping along with plantation of resistant tree species with susceptible ones, led to a healthy fungal community structure and promotion of a beneficial bacterial microbiome, thus proves as a potent practice for the suppression of Armillaria root rot and promotion of forest health.View record, Understanding fine-root adjustments to the environment and identifying factors that shape mycorrhizal fungal communities is a prerequisite for predicting the response and feedbacks of plants to global changes. Rhizopogon vesiculosus mycelia occurred deeper, were more spatially prolific, and colonized more tree roots than R. vinicolor mycelia. I show that Gram-negative bacteria and a species-specific community of mycorrhizal fungi are the primary consumers of rhizodeposit C among tundra shrubs. Franco) forests across a biogeographic gradient in Western Canada. Search. Sort by citations Sort by year Sort by title. My findings suggest that warming will alter the ECM community and nutrient cycling, which may facilitate Betula nana in tundra.
