Investigation Of The Effects Of Ocean Acidification On Juvenile Homarus Americanus Feeding Behavior, Sophia Roy
Honors Theses and Capstones
Climate change has led to increased CO2 absorption by ocean surface waters, resulting in decreased pH levels, a phenomenon known as ocean acidification (OA). A primary class of marine organism behavior is impacted by OA, in particular, olfactory-mediated behaviors related to foraging and feeding success. However, the biological mechanisms responsible for the documented impairment of foraging and feeding-related behaviors remains in question. We find that juvenile American lobsters (H. americanus) exhibit significantly faster rates of total feeding times in response to short-term low pH exposure. However, total search time and total handling time were not affected by pH when examined …
Assessment Of Open Top Chambers To Simulate Effects Of Climate Change On Soil Temperature And Cover Crop Response In Agricultural Systems, Gretchen Bahmueller
Assessment Of Open Top Chambers To Simulate Effects Of Climate Change On Soil Temperature And Cover Crop Response In Agricultural Systems, Gretchen Bahmueller
Honors Theses and Capstones
Climate change is expected to yield warmer winters that have the potential to place additional stress on our already stressed agricultural systems. Understanding how agricultural systems may respond to these changes is essential to creating crop and land management plans that ensure food security for future generations. To better understand how warming winters can/will affect air and soil temperatures and cover crop performance, open top chambers (OTCs) were deployed post cover crop seeding in a field experiment at the UNH Kingman Research Farm in Madbury, NH. The experiment consisted of four cover crop treatments sown into or after corn: an …
