We have a growing understanding of the light-sensing organs and light-influenced behaviours of animals with distributed visual systems, but we have yet to learn how these animals convert visual input into behavioural output. It has been suggested they consolidate visual information early in their sensory-motor pathways, resulting in them being able to detect visual cues (spatial resolution) without being able to locate them (spatial vision). To explore how an animal with dozens of eyes processes visual information, we analysed the responses of the bay scallop Argopecten irradians to both static and rotating visual stimuli. We found A. irradians distinguish between …
Characterizing The Temporal And Spatial Distribution Of The Cannonball Jellyfish (Stomolophus Meleagris) In The South Atlantic Bight, Lauren G. Faulk
Characterizing The Temporal And Spatial Distribution Of The Cannonball Jellyfish (Stomolophus Meleagris) In The South Atlantic Bight, Lauren G. Faulk
Theses and Dissertations
The cannonball jellyfish, Stomolophus meleagris, is commercially harvested throughout its range in the tropical and sub-tropical Americas, including in the South Atlantic Bight, where an estimated 4,000 tons (less than 2.4% of the estimated stock in South Carolina during the spring) are harvested annually. Like many Scyphozoan jellyfish, cannonball jellies have high interannual variability and little is known about the environmental drivers of their distribution and phenology. To better understand the ecology of this targeted species, we used fisheries-independent abundance data of cannonball jellyfish from 2001 to 2019 collected by the Southeast Area Monitoring and Assessment Program (SEAMAP) throughout the …
Cyclic Fluctuations Of Zooplankton Dynamics In A Tidal Salt-Marsh Basin, Jamaal Jacobs
Cyclic Fluctuations Of Zooplankton Dynamics In A Tidal Salt-Marsh Basin, Jamaal Jacobs
Senior Theses
Zooplankton are pelagic aquatic animals that are limited in their movements by the water currents around them and are major links in aquatic food webs between primary producers and higher trophic levels. Their populations are temporally and spatially variable, as they are sensitive to changes in salinity, temperature, and dissolved oxygen. This is especially true in highly dynamic environments, like estuaries, where environmental conditions are highly variable across seasonal and daily cycles. In order to examine the variability in zooplankton populations across a tidal cycle, we collected zooplankton samples from North Inlet Estuary at 30-minute intervals over a half tidal …
