Evaluating The Capacity Of Ascophyllum Nodosum Habitats To Act As Carbon Sinks In The Gulf Of Maine, Megan Sinclair
Evaluating The Capacity Of Ascophyllum Nodosum Habitats To Act As Carbon Sinks In The Gulf Of Maine, Megan Sinclair
Honors College
Some coastal ecosystems are defined as being carbon sinks for their ability to absorb more carbon than they release as a result of their high primary productivity. There has been support for the claim that macroalgal communities can act as carbon sinks and reduce levels of CO2in seawater through photosynthesis and potentially mitigate some local effects of climate change (Chung et al., 2011; Chung et al., 2013; Hill et al., 2015; Sondak et al., 2017). Within the state of Maine, rocky intertidal zones are coastal ecosystems that are particularly vulnerable to climate change and dominated by Ascophyllum nodosum (rockweed) communities …

Effects Of Ecologically Realistic Heating Profiles On Feeding In The Intertidal Hermit Crab, Pagurus Sameulis, Paige Davis
Student Scholar Symposium Abstracts and Posters
The intertidal zone is an ideal habitat to investigate effects of global warming because species living in it are very close to their physiological limits. Initial studies of invertebrate physiological responses to heat stress have employed relatively abrupt increases in temperature. My research investigates effects of ecologically more realistic temperature profiles on feeding in the intertidal hermit crab, Pagurus sameulis. Recent work in the Wright lab showed that feeding in this species is inhibited by an abrupt increase in temperature. Because temperature change in the natural environment of Pagurus is much more gradual, I hypothesize that such a gradual temperature …
