Ecology & Biogeochemistry of Macroalgae
Session ID#: 85361
Session Description:
Macroalgal primary production structures many nearshore systems by physically engineering habitat and fundamentally altering biogeochemical processes. The development and advancement of remote sensing, physical oceanographic instrumentation, and sequencing technologies are greatly expanding our understanding of the ecology of macroalgal communities and the influence of these communities on carbon and nutrient dynamics in the coastal environment. For example, aerial hyperspectral imaging are vastly enhancing the spatiotemporal resolution of macroalgal physiological state monitoring; while advancements in genomic analysis are elucidating shifts in macroalgal microbiomes from healthy to diseased states. Synthesis of these interdisciplinary studies is key to constructing frameworks for predicting the potential effects of current and future ocean change on coastal macroalgal ecology and cycling of key elements (e.g. carbon and nitrogen) in coastal regions.
This session focuses on the technological advancements and interdisciplinary studies that are enhancing our understanding of macroalgal ecology and the influence of various macroalgal species on coastal carbon and nutrient cycling. Presentations that highlight developments in our understanding of invasive species, macroalgal microbiomes, phase-shifts on coral reefs, macroalgal health, and other topics related to macroalgal ecology and controls on coastal biogeochemistry are encouraged.
