Topics include recruitment, disturbance, physiological tolerances, competition, predation, and how these processes influence the structure and diversity of marine communities. Students will develop skills in algal and invertebrate identification, data collection, data analysis, and scientific reading and writing. One weekend field trip is required. 5 credits, ad-hoc W credit Required materials: Field notebook (Rite-in-the-rain with pencil) M.J. Kaiser et al. 2005/2011.

All papers should be submitted to dropbox. Class includes 2 weekend field trips, plus 2 field trips during Monday afternoon labs. Performance in this portion of class is based on field notebooks. Class includes 3 indoor labs (photosynthesis, plankton, grain size analysis) and 2 computer labs (on-line ocean data sources, diversity indices). Performance is based on successful completion of handouts. Class includes 2 computer labs for statistical analysis of data collected by the class. Performance is based on successful completion of handouts. We are very serious about the importance of class participation, labs, and field trips – there is no other way to learn natural history and how to do research in marine ecology. Missed field trips and labs cost 0.5 GPA. Students are responsible for avoiding plagiarism in all written work. p. 2 Term paper Students will select a topic in small groups from among the following, related to this year’s class theme. Students will work together to design and implement the study but will carry out the background research and write-up separately. - Abundance of clams recruiting into habitats with different structural complexity (e.g. above-ground structure from vegetation or reefs; grain size of sediment) - Abundance and diversity of amphipods in habitats with different structural complexity (e.g. above-ground structure from vegetation or reefs, edge vs center [see text 331]; with and without deterrent) - Abundance and diversity of primary and secondary space occupants on boulders of different sizes experiencing different frequencies of disturbance by overturning (text p. 462) - Bird abundance and diversity on intertidal flats differing in habitat structure - Life history response of eelgrass following disturbance (see text 329-331) - Organism performance or diversity along a stress gradient (text p. 463) By Friday Apr 22, provide the following: 1) major hypothesis, 2) annotated bibliography of 10 relevant papers found in an initial search in Web of Science. Explicit how-to instructions can be provided for those unfamiliar with electronic searches of primary literature. Organization for the data paper is as follows: Title Abstract (200-300 words) Introduction: 1st paragraph begins with major ecological concept of interest. Justify, usually by explaining and citing other work. Final paragraph ends with specific questions or hypotheses to be addressed in the remainder of the paper. Methods: state in way that your project could be carried out by someone reading the methods. Sub-headings often include: Study site; Study species; Study design; Data analysis Results: Include 1 table or figure for each major point you wish to make about the results Discussion: briefly summarize results, talk about problems with the project, and relate results to similar studies in the literature References (at least 10): format according to the journal Ecology The paper should be about 10 pages at 1.5 spacing. The draft is due 29 May at midnight, and responding to comments will improve the score and provide ad-hoc writing credit. Final paper is due 12 June. p. 3 Natural history paper This paper should be about 5 pages. All writing and thought should be original (that is, no need to cite references). Imagine you are Lewis and Clark seeing a spot for the first time. How would you describe it so that people back east get a sense of the organisms, habitat, interactions, and other important processes? You may write this paper in any of a variety of styles, including a background for a research project, travelogue, journal, written from the perspective of some organism that lives on the beach, a guide for visitors to the beach, etc. However, every paper needs to include the following information (the paper will be clear but boring if you use these as section titles – your choice): 1. Location – what place you selected to visit and to explore its natural history 2. Date/Time – when you visited the beach, and how things changed during your visit (specifically with respect to the elevation of the tide, but also including weather events if notable) 3. Habitat – You will need to take measurements of characteristics such as the distance between high and low tides, size of cobble, rocks, or boulders, percent cover of mud or sand in several quadrats, etc. You should place your site in a general habitat category (according to the categories of Dethier), or note if habitat is patchy at your site. You should also note any human-constructed habitats. 4. Oceanography – develop hypotheses about the extent to which your site is influenced by currents, freshwater inputs, and waves. Habitat has some clues, as does thinking larger scale – where do prevailing storms come from, and is there a lot of fetch for waves to develop? Which way does the beach face, and how does this affect temperature and desiccation? 5. Zones – You should divide your site into 4 zones, namely subtidal (below 0), low intertidal (from mean lower low water to mean tidal level), high intertidal (to mean higher high water), and supratidal (where only extreme high tides can reach). Obviously you will have to use some creativity to discover these zones, including consulting a tide schedule and looking for distinct assemblages of organisms. Describe the habitat of each zone, including how much space is bare vs. occupied, and describe the 2-5 most conspicuous species present – identify them to species if possible, but at least to phylum. Use replicate, random quadrats in each zone to collect quantitative data about which, and how many, species are present. If possible, figure out if these taxa are native or introduced! (Ask around, and use a key.) 6. Processes – This is the most creative and important part. You don’t need to cover every single ecological process that is going on, but select 2-3 and cover them in detail. For inspiration, you can look for processes in action: predation (something eating something else, or evidence of mortality), competition (something overgrowing something else, or two things that probably use similar resources), facilitation (for instance, organisms that live associated with others), recruitment (size structure in a population tells you something about this), production (which organisms contain most of the biomass? Which organisms probably grow fastest?), nutrient cycling (look for detritivores). [reproduction, camouflage…] Processes can also include human impacts, such as collection, trampling, pollution, or alteration of habitat. p. 4 Field notebook For scientists, a good notebook includes ideas, observations, and data. It should spark memories and be a source of inspiration years later, as well as making it possible to reconstruct experimental methods and results. If you genuinely want to keep your notebook at the end of this course, then you’ve achieved a good portion of what we want you to do. Specifically, however, each time we are in the field you should include the following information. We will grade you in part on how well you cover each of these headings: 1. Date 2. Location 3. Today’s weather: precipitation, temperature, wind 4. Habitat type: Rock (what type?) or soft (what grain size? Sand or mud?). Patchy or continuous. Slope and aspect (facing direction). Wave exposure (including aspect and fetch). Biogenic habitats (constructed by marine organisms). 5. Human impacts: human-constructed habitats, number of people present, activities going on 6. Major organisms present at each tidal elevation: Zone 1 (supralittoral fringe above normal high tide), Zone 2 (upper midlittoral zone), Zone 3 (lower midlittoral zone), Zone 4 (infralittoral zone below normal low tide), Tidepools if present 7. DRAW the form of the shoreline as a whole 8. DRAW examples of 3 major organisms at 2 tidal elevations. Use a separate page for each elevation. 9. Each field trip will have some component of quantitative data collection. Your notebook needs to include information about methods that would allow you to duplicate your study based on those instructions. You should: note the hypothesis being tested, briefly explain the methods (including, for instance, quadrat size and total number), set up a data table and record results. This strategy also applies to data collected in lab. Feel free to wax eloquent in your notebook, wonder, ponder. p. 5
