Observations and Experiment:
Morphologies and Life History
Native vs. Invasive
Tunicates in Immunology
Organisms in the Rocky
focuses on two ascidians that frequent intertidal zones,
harbors, and estuaries of the northeastern Atlantic
coastline. Botryllus schlosseri and Botrylloides
violaceus, commonly known as sea squirts or tunicates,
protochordates that have become widespread due to fouling on boat hulls and introduction for
B. schlosseri, the star tunicate, earns its nickname
for the star-like appearance of the zooids. B. violaceus,
the orange or red sheath tunicate, is brightly colored with
a less definitive arrangement of densely clustered zooids.
Both organisms form mats that are generally most
prevalent on man-made structures such as floating docks or
pilings. Over the course of this semester,
made of settlement frequency and distribution of B.
schlosseri and B. violaceus on natural
substrates. Supplemental literature research was also done
on native vs. invasive implications, and immune response and allorecognition in ascidians.
