Marine Biology & Ecology will explore the diversity of biological and ecological processes that shape life in the oceans. We will place a special emphasis on marine life in New England, focusing on the interactions between humans and the sea. This focus will lead to a greater understanding of the consequences of ongoing environmental changes in the 20th and 21st centuries.

Required Assignments:

Regular Essays: I realize that for some of you this class is your first encounter to the primary literature, and it can be a bit daunting. As such, we’re going to change the weekly assignment to help you make sure you’ve fully understood the reading and can begin to dig into it intellectually before class.

For each class we have scientific papers assigned, choose one of the papers assigned and in 1-1.5 pages, no more, in 12 point single spaced font. Answer the following four questions:

1) Why are the authors writing this paper? What larger body of ideas does it sit within?
2) What were their hypotheses, and how did they test them?
3) What did their findings teach them about their questions or ideas of interest?
4) Are you persuaded by what they have done? Why or why not?

Feel free to also discuss any insights you have about the work presented from outside of class. Many of the papers we read will revolve around the natural history of New England. Were there any particular points of connection that this paper made with your own experiences? Did it make you think about any particular issue differently?

Essays will be marked as completed or not. Essays that provide no more detail than the abstract of the paper will be marked as not completed.

Midterm Paper: There are two options.

Option 1 – I came here for an argument: Students will select one pair of papers from a list of papers that famously disagreed with one another. Students should read the papers and at minimum 3 associated papers from the reference list to understand its context and 2 papers that cite it (use Google Scholar). Students are then asked to write a short persuasive essay (5 pages max.) that 1) summarizes the papers main arguments, 2) states compares and contrasts the differing points of view, 3) argues which one got it right.

Option 2 – North versus South: When the first edition of Marine Community Ecology by Bertness et al. came out, a parallel text by Australian researchers was also published. The two differ greatly in focus of examples, papers cited, and authors of chapters. The current edition has much more back and forth between the southern and northern hemisphere. Read one chapter from the first edition, it’s parallel from the Australian Marine Ecology (Connell et al. eds), and write a short essay (5 pages max) that 1) compares and contrasts the two chapters, 2) elucidates what is gained by taking a broader perspective across multiple academic groups, and 3) discusses whether there is generality to the principles in either text or if local examples cannot be generalized. Students may also explore how the 2nd edition of Bertness et al. synthesizes these two points of view. Students should also explore the original references (at least 2-3) cited by the chapters.

Students will be graded equally on their accuracy, understanding of the material discussed, the strength of their argument, and the style of their writing. Grammar and spelling count. Students will be given an opportunity to revise and resubmit.


Final Project: Students have the choice of either taking a final written exam during the exam period or presenting a final interdisciplinary project. As students are entering the course with varying backgrounds and interests, the interdisciplinary project is designed for students to address the course material using their own perceived strengths – even if they are outside of the scope of a formal marine science education. Interdisciplinary projects can take several forms: 1) a grant proposal for future work complete with preliminary data from the literature, 2) a film (animation, music video, documentary, etc.) exploring a paper or theme from class,

See http://www.youtube.com/user/iambient33 and http://creaturecast.org/ for examples 3) a piece of original research with accompanying writeup ranging from taking data in the field, from online databases (e.g., http://marinexplore.org), building a new sensor or marine tool (e.g., SeaPerch ROV), a survey of people regarding attitudes or knowledge of relevant issues, etc. 4) other piece of creative work. Projects falling outside of these areas but demonstrating a connection between the course material and the students’ knowledge are essential. Projects other than the grant proposal can be done in groups. All projects must be approved by the Professor by November 1st. Projects will be graded on a demonstration of mastery and understanding of topic material in the context of the work. Projects will be presented to the class at large on the last day of classes.

Leading a Discussion: Throughout the semester students will be asked to lead 1-2 discussions of academic papers.
