Partner’s Name:_________________________The role of Kelp in the Devereux Beach EcosystemSelf-guided Field Trip (Part 1 of HW3, due Monday, Aug.28th)YOUR NAME:__________________________ Date/Time:____________________Partner’s Name:_________________________Observation site #1: Look at the beach and water from the top of the bluff. There is a good bench to sit on about 100 yards to the right of the staircase.Weather (wind, % sunshine, temperature, fog, water clarity): ________________________________________________________________________________________________________________________________________________A. How (if at all) is the water texture (due to wind waves) different inside and outside of the kelp beds?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________a. What effect does the kelp appear to have on beach and cliff erosion?________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________B. Describe the organization of kelp on the beach (patches/clumps, in bands parallel to beach, etc.). Offer a plausible explanation for your observations.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Sketch a picture of your observations, below.D. Human Values. Do people seem to like the kelp? (If you go when people are sun-basking, note the average distance between people and kelp clumps, or ask/interview a couple of folks about their enthusiasm toward kelp on your way to Observation site #2).________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________At home, investigate the value of kelp to humans: What is kelp used for? Why is it harvested? Based on your observations and research, how wouldkelp harvest affect the sandy beach ecosystem (if at all)? Explain.________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Observation site #2: Walk down the beach toward the abandoned (heavily spray-painted) house. If you go to this site on Thursday, between 9 and 5, there will be abox of ES100 investigation tools for your use. Please use gently and return.A. Find a relatively impact strand of kelp. Draw it, below, and suggest what function of each part of the plant is (you can confirm or revise your guesses at home, if you want to).B. Investigate how the abundance (how many of each critter type) and diversity (how many different types of critters) changes as you walk from the water’s edge to the cliff. (see diagram, next page)**Tips on locating critters: lift things up (i.e. dead kelp), explore, look in crevices, dig, look for signs of life (holes in the sand, poop, carcasses, etc.). Look above (birds) and below (burrowers) the surface!!!What did you find? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Sketch a picture, indicating areas of high/low abundance and high/low diversityExplain your observations above, using the terms: limiting factor, selective pressures and niches. When thinking about what factors promote (or inhibit) species diversity, you maywant to consider the acronyms Cl.O.R.P.T.H and S.O.D.)__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________WaterCliffWalk perpendicular to the water’s edgeC. Observe an animal foraging (could be a bird, insect, reptile, etc.). Draw the organism, and identify (later, if necessary): Discuss how its physiology and/or foraging strategy enhances its net energy intake. If it doesnot appear to be optimally foraging, explain how energy appears to be
