Berenice Yang Gonzalez Intertidal Lab Abstract The intertidal zone is characterized as the limited segment of domain which is found at the air-land-ocean interface and lies between the tidemarks on all shorelines. From the about dry high tide line down to the quite often wet low tide line, the intertidal zone exists on rough shores, sandy shorelines, and mud pads. The Intertidal Zone is a harsh environment. The class sample the intertidal zone by placing quadrats in a standardized form and recorded all species who were in the quadrat. The Shannon Index and Evenness were calculated in 4 transects in the mid zone. The Simpson’s Index and Richness were calculated in all three sections separately and all values were compare to understand the dynamic of this community. Two species were compare from the sample population to understand the relation of the zones and niches. The sample was too small and many error were made for the sample to have a relevant result. Introduction The intertidal zone is a severe environment that has various stressors and forces which act on organisms that are not found in strictly marine or terrestrial environments. This environment is unique due to the constant fluctuating water levels which exposes organisms to air and the forces of crashing surf that only animals and plants with special adaptations are able to withstand. Despite all of these environmental conditions, these species are able to survive and reproduce within extreme environments.
