This email includes a general outline and key points for exam 4. As a reminder, it is definitely a good idea to review all the practice and graded quizzes for the sections that will be covered on the exams, as well as the learning objectives. Intertidal habitats oarea between high & low tide line oabiotic stresses: oair exposure (emersion) Adaptations: move & seek wet areas, if sessile: close shells & live in groups to prevent desiccation otemperature and salinity fluctuations. Adaptations: if mobile: seek wet areas, be lightly colored to reduce heat absorption from sun owave action. Adaptations: be flexible, strong attachments, live in groups obiological stresses opredation ocompetition. Subtidal habitats obelow low-tide line okelp forests ohighly productive ofound in temperate, rocky areas oimportant habitat onot true plants: very fast growing osandy beach & mud flat. Particle size: determines interstitial space, how much substrate shifts, burrowing, size & sorting: determines amount of water that penetrates, determines oxygen levels.
