His research focus has been on the role of microbes as mediators of interactions between plants and herbivores. He completed a bachelor\u2019s degree in biology at Trent University, and an MSc at York under the supervision of Professor\u00a0Dawn Bazely. At York, he studied the impact of grazing by feral sheep on the symbiosis between grasses and asymptomatic, toxin-producing fungi (endophytes) in the St. Kilda Archipelago of Scotland.<\/p>\n\n\n\n<p>Vicari was awarded a Commonwealth Scholarship to pursue a PhD at Lancaster University in England, where he studied the impact of mycorrhizal (below-ground) fungi on the relationship between plants, herbivores and foliar (above-ground) endophytes. Following his PhD, Vicari returned to York as a sessional instructor and taught courses in ecology and evolution for the Biology and Geography departments and the Natural Science Division. He continues to collaborate on research projects with Bazely.<\/p>\n\n\n\n<p>Vicari's current research interests include the effects of herbivore saliva on the plant microbiome. He looks forward to integrating citizen science projects with a conservation focus into ecology courses in the Biology Department. In particular, he aims to explore ways \u2013 through public outreach \u2013 to increase awareness of, and action against, the biodiversity crisis \u2013 one of the most pressing challenges of our time.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"template":"","department":[3],"research-area":[15],"un-goal":[],"research-method":[],"graduate-program-membership":[],"graduate-program-physics":[137],"admin-faculty-title-department":[],"program":[],"class_list":["post-3875","faculty","type-faculty","status-publish","hentry","department-biology","research-area-ecology","graduate-program-physics-137"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Mark Vicari - Faculty of Science Profiles<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.yorku.ca\/science\/profiles\/faculty\/mark-vicari\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Mark Vicari - Faculty of Science Profiles\" \/>\n<meta property=\"og:description\" content=\"About Mark Vicari joins the Department of Biology as an assistant professor.
