EEB Seminar – 16 February

This week EEB welcomes John Serafini from the Department of Biology, Queen’s University:

Effects of resource manipulation on temperate grassland vegetation under a changing climate


It is predicted that by modifying circulation patterns and hydrologic processes climate change will strongly alter global precipitation regimes. From an ecological perspective, this prediction has garnered extensive concern and curiosity because water availability is the primary regulator of plant productivity and competitive interactions in many terrestrial ecosystems. Extensive research has consequently explored how precipitation regime changes might alter ecosystem functioning, with the majority of these experiments manipulating soil moisture availability in water limited ecosystems. The impact of altered rainfall on plant productivity relative to other key environmental factors is however less clear for mesic environments characterized by a stable supply of moisture. To address this research need, my Master’s research has explored how the interaction of below-ground water and nutrient availability and above-ground herbivory, each of which are important regulators of plant growth, determine the productivity and composition of grassland plant communities within Eastern Ontario’s temperate climate.

The EEB Seminars run weekly, on Thursdays, in the EEB Lounge of the BioSciences Complex, Room 4338, from 12:30-1:30pm. Light refreshments are served starting at 12:15.
