May 4th
Today got off to a slow start, as we are all feeling the effects of long days out on the water and late nights in the lab. However, a rejuvenating breakfast of bagels and cereal got us in the mood for our morning lecture. In lecture, we reviewed trophic cascades, looked at numerous food webs, and discussed how each trophic level can be greatly affected by the addition or removal of just one primary species. For the reflection of the day, David Jantz highlighted a past article concerning positive interactions. He noted that throughout nature, he readily observes competition and death, but has recently begun to perceive and appreciate the vast number of mutualistic interactions present in nature.
Following lecture and morning announcements, each group ventured out to observe their selected sites and collect data. Most research groups set off for Triton Flats, while others explored the nearby area of Zane Grey Creek. My research group took a short trip to Anne’s Beach. There, we collected and observed hundreds of gastropod shells and hermit crabs, mainly the white-striped (Clibanarius vittatus) and tricolored (Clibanarius tricolor) hermit crabs, occasionally collecting unknown species to identify later in lab.
We returned to the marine biology facility and reconnected with our peers, sharing stories while enjoying a quick lunch. Our second lecture of the day covered the phylum Mollusca, led by the gastropod-loving Duane Kauffmann. We all appreciated the supplemental pictures of gastropods he has collected –he has been a great help with identifying organisms in lab! We have all enjoyed talking to him and listening to his many stories over the past week. We’re sad to say goodbye, as he is headed back home tomorrow. Have a safe trip home Duane!
