A Histological Assessment Of The Effects Of Elevated Temperature And Nitrogen On The Symbiodinium Of Palythoa Toxica (Walsh And Bowers 1971), Molly Westbrook
A Histological Assessment Of The Effects Of Elevated Temperature And Nitrogen On The Symbiodinium Of Palythoa Toxica (Walsh And Bowers 1971), Molly Westbrook
Honors College
Coral reefs around the world are suffering mass bleaching events caused by a combination of stressors, including rising ocean temperatures, acidity, pollution, increased suspended sediments, and increasing nitrogen levels. Corals harbor a complex microbial ecosystem consisting of bacteria, and algal symbionts known as Symbiodinium. This study examines the effects of elevated temperature, a known cause of bleaching, and elevated nitrogen, an increasingly important potential stressor for reefs, on the Symbiodinium of a zoanthid coral, Palythoa toxica. A total of 65 polyps were subjected to 5 different water treatments of 2 levels of elevated nitrogen, and 2 levels of …

Short-term (6 months to 17 years) glaciochemical records have been collected from several glacier basins in the mountains of central Asia. The spatial distribution of snow chemistry in central Asia is controlled by the influx of dust from the large expanse of arid and semiarid regions in central Asia. Glaciers in the Northern and Western Tibetan Plateau show elevated concentrations and elevated annual fluxes of calcium, sodium, chloride, sulphate and nitrate due to the influx of desert dust from nearby arid and semi-arid regions. Glaciers in the Southeastern Tibetan Plateau show lower concentrations and lower annual fluxes of major ions …
