Members of which have calcareous bases (Cornwall 1951) the genus Semibalanus, which was described and base forms unique starry pattern (Fig. 1), (initially as a subgenus) by Pilsbry in 1916, especially in juveniles (Fig. 3) (Ricketts and differ from Balanus species with the presence Calvin 1971). of membranous bases (Newman and Ross Wall: Formed by plates and is thick 1976).

  • Urchin Rocks-NW Island Transect Study 2020
    The Long-term Effect of Trampling on Rocky Intertidal Zone Communities: A Comparison of Urchin Rocks and Northwest Island, WA. A Class Project for BIOL 475, Marine Invertebrates Rosario Beach Marine Laboratory, summer 2020 Dr. David Cowles and Class 1 ABSTRACT In the summer of 2020 the Rosario Beach Marine Laboratory Marine Invertebrates class studied the intertidal community of Urchin Rocks (UR), part of Deception Pass State Park. The intertidal zone at Urchin Rocks is mainly bedrock, is easily reached, and is a very popular place for visitors to enjoy seeing the intertidal life. Visits to the Location have become so intense that Deception Pass State Park has established a walking trail and docent guides in the area in order to minimize trampling of the marine life while still allowing visitors. No documentation exists for the state of the marine community before visits became common, but an analogous Location with similar substrate exists just offshore on Northwest Island (NWI). Using a belt transect divided into 1 m2 quadrats, the class quantified the algae, barnacle, and other invertebrate components of the communities at the two locations and compared them. Algal cover at both sites increased at lower tide levels but while the cover consisted of macroalgae at NWI, at Urchin Rocks the lower intertidal algae were dominated by diatom mats instead. Barnacles were abundant at both sites but at Urchin Rocks they were even more abundant but mostly of the smallest size classes. Small barnacles were especially abundant at Urchin Rocks near where the walking trail crosses the transect. Barnacles may be benefitting from areas cleared of macroalgae by trampling but in turn not be able to grow to large size at Urchin Rocks.

  • Cirral Length and Wave Exposure in the Barnacle, Semibalanus Cariosus
    Cirral Length and Wave Exposure in the barnacle, Semibalanus cariosus By: Jennifer Maciejeski Introduction Barnacles are very prevalent on many coasts throughout the world's oceans. They are suspension feeders that filter food from the water column. They are attached to rocks, wood, or even living organisms in the water. During their larval stage oflife, barnacles are mobile and at this stage find a substrate to land on and spend the rest of their adult life on. They attach onto a surface with their heads and cement themselves down and then secrete the shell material to make their calcareous plates that protect their soft bodies. Since they are non-mobile for most oftheir lives as an adult, barnacles depend on water flow to bring food to them. To collect food from the water, barnacles use their feet (cirri) which are facing upward from their calcareous plates, to bring in particles (Ingram 2007). In order for the cirri to work, barnacles must have some form of water flow. An example ofa large species ofbarnacle is the thatched barnacle, Semibalanus cariosus. The thatched barnacle is found in the mid intertidal to shallow subtidal, many times underneath the thickest band ofacorn barnacles in the low intertidal. They range from Alaska to Central California on the West Coast ofthe United States as well as in some parts ofJapan. They are generally found on rocks, floats, or pilings with a high number found on steep shores with current and waves, though on the open ocean they are usually in cracks or protected areas. S. cariosus can be found often times in aggregations with other individuals, and can be tall and narrow when in large groups.

David Clare, a PhD candidate studying marine ecology at the University of Liverpool, Helen Hess, of College of the Atlantic, Karen James, of MDIBL, and volunteers Genevieve Davis, Eliza Rockefeller, Paige LeDuc, and Grace Drennan also contributed to project efforts. Dr. George Kidder is particularly acknowledged for his facilitation of travel to the field sites and for designing and creating some of the necessary sampling equipment. Our interns who were not specifically assigned to this project are acknowledged as Lukas Thorburn contributed to map- building and, along with Hanna Mogensen, helped with field-work and sample processing. Ashley Heinze conducted analysis of photos to determine percentage cover of mussels in restoration areas. Duncan Bailey helped us grapple with Microsoft Access and Jordan Bailey brought public exposure to our work by bringing a reporter out to observe our field sampling. This project would not have been possible without the Bangor High School group whose members contributed a great deal of time and energy to facilitating travel to field sites, conducting field work, processing samples, identifying organisms, and supporting the project work even after their time at MDIBL was completed.
