In a field trial utilizing seedling bioassays, the role of mycorrhization of western redcedar and western hemlock on seedling growth was evaluated; reciprocal forest floor transfers from uncut forests were incorporated into the project design as inoculation treatments. Our results highlight the existence of multiple axes of within-species fine-root adjustments that were consistent with a potential increase in fine-root acquisitive capacity with environmental limitations.Next, to better integrate mycorrhizal symbiosis into trait-based plant ecology, we combined trait measurements of fine roots and ectomycorrhizal fungi with next-generation sequencing. WANG, Tongli. Search. 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. Suzanne Simard est professeure d'écologie forestière et enseigne à l'Université de la Colombie-Britannique.. Elle est biologiste et a testé des théories sur la manière dont les arbres communiquent entre eux. 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. TED Radio Hour (3:15 mark) It’s communication. glauca (Beissn.) Sort by citations Sort by year Sort by title. To address this, I co-created the digital plant-centric action-based game Shroomroot for use in lower level postsecondary settings. https://gustavus.edu/events/nobelconference/2018/simard.php Both species were associated with moist microsites within plots, and had more prolific mycelia in mesic compared to xeric plots. Year; Net transfer of carbon between ectomycorrhizal tree species in the field. In the FH horizon, the relative abundance of the saprotrophic fungal community declined while that of ectomycorrhizal (ECM) fungal community increased with stumping. glauca (Beissn.) These are fungi that are beneficial to the plants and through this association, the fungus, which can’t photosynthesize of course, explores the soil. I found no evidence of C transfer between seedlings through growth chamber ¹³CO₂ labeling, but D₂O labeling and natural abundance H₂¹⁸O measurements are suggestive of increasing water transfer from donor to receiver seedlings as receiver water deficiency increased.View record, Anthropogenic climate change threatens the stability of Arctic C stores. In the first experiment, regeneration failed in all canopy gap sizes and network treatments due to the harsh climatic conditions. Fungal α-diversity in the A horizon increased with stumping regardless of tree species composition and had a tendency to increase in the FH and B horizons. Dr. Suzanne Simard is a Professor of Forest Ecology at the University of British Columbia (UBC) and the leader of The Mother Tree Project. 2424 Main Mall. Publications by Author: Allen Larocque Alice Chang Amanda Asay Brian Pickle Camille Defrenne Elana Evans Gabriel Orrego Katie McMahen Laura Super Monika Gorzelak Suzanne Simard Teresa Ryan Recent Selected Publications Refereed Journal Articles, Published […] Molecular and phylogenetic techniques were utilized to compare mycorrhizal fungal diversity between forest types and to identify mycorrhizal fungal associates of the plant species occurring in clearcuts. Cited by. Both a greenhouse and field experiments were performed to corroborate results. could influence interior Douglas-fir stand dynamics and resistance to water stress.View record, The McLure fire of August, 2003, affected over 26,000 hectares in the interior of British Columbia. As a consequence, trait-based plant ecology, which has mostly focused on above-ground traits, is increasingly placing the emphasis below-ground.To improve our functional understanding of fine roots, we first quantified root morphological, chemical and architectural trait variation in interior Douglas-fir (Pseudotsuga menziesii var. Last updated: October 1, 2020 @12:30 pm The treatments were replicated across three geographically distinct sites within the same BEC subzone (ICHmw). But, just as with Lynn Margulis and her glauca) forests, particularly as climate changes. Suzanne Simard. Her research is highly collaborative, working with industry, government, communities and academia. With colleagues at UBC, she launched TerreWEB, an innovative graduate training program that integrates global change science, social science and communications research.
