However the ecol ogical consequences of this increase are not well understood. DOC from ter restrial sources stain lake waters a dark brown color\, and can have stron g effects on the physical and biological structure of lake ecosystems. Thi s occurs through its associated light and heat attenuating properties\, wh ich reduce thermocline depths\, and thus the area of light\, warm\, and we ll-oxygenated habitat in DOC-rich lakes. Recent work has shown that fish p roductivity decreases along a gradient of increasing DOC\, however the mec hanisms behind this have not been fully explored. Here\, Nicola demonstrat es potential mechanisms for this loss in productivity by determining how D OC affects zoobenthos\, a primary prey item for many fish\, as well as how DOC affects fish feeding efficiency and life history strategies.\n\nEvery one in the ºÚÁϲ»´òìÈ community is welcome to attend a PhD oral defense. Pleas e join us in celebrating the accomplishments of our PhD candidates.\n\n \n \n \n DTSTART:20160329T131500Z DTEND:20160329T131500Z LOCATION:MS2-022 (Faculty Lounge)\, Macdonald-Stewart Building\, CA\, QC\, St Anne de Bellevue\, H9X 3V9\, 21111 Lakeshore Road SUMMARY:PhD Oral Defense: Impacts of dissolved organic carbon on productivi ty of fish and benthic macroinvertebrates in north temperate lakes URL:/macdonald/channels/event/phd-oral-defense-impacts -dissolved-organic-carbon-productivity-fish-and-benthic-macroinvertebrates -259483 END:VEVENT END:VCALENDAR
