Course Description
This course is a hands-on introduction to the marine invertebrates inhabiting the waters of Cape Cod.  We will combine lectures, field collections, and laboratory observation to familiarize students with the diversity of invertebrates in the local region and explore selected aspects of their function, ecology, and evolution.  Field studies will include trips to marsh, estuarine, and rocky intertidal habitats and a cruise to subtidal environments.  Class meetings will be concentrated in September and October when the animals are plentiful, the water warm, and the weather good.  Students will present subjects orally in class, conduct a field or laboratory research project, and participate in a lab practicum .  Textbooks will be available in the reading room at Redfield and will be supplemented with guides to local fauna.

Key: F = field trip, L = lab/lecture, P = students present a published paper, S = students present their own research
* Field trips will be scheduled on M or W
Classroom location:  Redfield 1-32

Field trip (F) classes are expected to take all morning (about 3hrs).  Lab/lecture (L) classes will involve 1/2-hr of hands-on observations, followed by a 1-hr lecture.  Two class sessions are set aside for 20-min student presentations of primary literature (P).  An additional two class sessions are set aside for 30-min student presentations of original research projects (S), and the final class session will be an end-of-semester lab practicum .  We will meet a total of 17 times over the ten weeks, but 4 of these class periods will be < 1 hr. 

Lectures (given by):
L1 (Mullineaux/Beaulieu): Introduction to invertebrate phyla, with hands-on sorting of a variety of habitat samples
L2 (Beaulieu): Porifera, Cnidaria, and Ctenophora (and, briefly, Bryozoa)
L3 (Mullineaux): WormsI-- Annelida
L4 (Beaulieu):  WormsII-- Platyhelminthes, Nematoda, Nemertea, Sipuncula, Echiura, Chaetognaths, and Enteropneusts
L5 (Mullineaux): Mollusca
L6 (Mullineaux): ArthropodsI
L7 (Mullineaux): ArthropodsII
L8 (Rakow): Urochordata
L9 (Beaulieu): Echinodermata

Field trips:
F1 : Walk on Woodneck Beach (marsh, beach, and rocky intertidal) low tide 14 Sep. 10:45AM
F2 : Barnstable Harbor at Scudders Lane (marsh) low tide 26 Sep. 1PM (leave WHOI at 11AM, return 4PM)
F3 : Afternoon cruise on R/V Gemma in Vineyard Sound

Plus optional field trips:
1) Snorkeling at WHOI pier (Mon 5 Sep. 10AM prior to L1 and **night** Wed 5 Oct. 6PM)
2) Provincetown low tide for sipuncs and nemerteans (Sun 18 Sep. prior to L4)
3) Evening snorkel at Sandwich Town Beach (Sun. 16 Oct. low tide just before sunset)
4) Join Regina Campbell-Malone's class field trip on 29 Oct.
Check tides.

Grading
30% Independent research project.  The project may be any original work involving a field or laboratory study of local inverebrate fauna (laboratory projects limited to whole organism studies such as behavior, feeding ecology, or physiology).  We prefer that students work together in pairs for these projects.  Example field studies would be: mark-recapture study of gastropods on rocks at Woodneck Beach, weekly survey of residents in delimited area on Iselin pier piling.  The oral presentation (S1 , S2 above) may include hands-on activities in addition to the typical AGU-type presentation format.  The written report will be in typical (but abbreviated) manuscript format: abstract, intro, methods, results, discussion, and references.  
20% Oral presentation (P1, P2 above) of a paper from the published literature that describes some aspect of the ecology or evolution of a local invertebrate species.  Here is an example: Cohen, A.L. et al. 2002. The effect of algal symbionts on the accuracy of Sr/Ca paleotemperatures from coral. Science 296: 331-333.  Other examples would be: papers on the biomedical relevance of local horseshoe crabs, fisheries research on clam or scallop populations, larval settlement of local fauna, bioluminescence or seasonal strategies of zooplankton in local waters.  This ~20-min presentation will be somewhat informal (show-and-tell), involving maybe a figure or two from the manuscript.
25% Class participation.  During each of the 3 field trips, one or a pair of students will act as "scribe," recording notes and a list of organisms/samples collected.  These notes will be submitted within a day or two for Beaulieu to prepare a webpage for each field trip, including the notes and any digital photos.  During each lab session, each student will be assigned a particular body system (for example the reproductive or circulatory system) to learn somewhat in-depth.
10% Notebook with observations from field trips and laboratory investigations of specimens.
15% End-of-semester, general lab practicum for identification of local organisms and their body systems.
