  1. Rocky Shore Habitats Annie Russell

  2. School of Marine Science and Technology

  3. Aims for today • What are the factors that affect the distribution of an organism on the rocky shore? • How have the organisms become adapted to the rocky shore? • From your observations of the organisms on the rocky shore give specific examples of how the organisms observed have adapted to survive the rocky shore environment.

  4. Polar oceans Coral reef Marine habitats Rocky Shores Deep sea oceans Open oceans

  5. How does all this affect the Rocky shore at cullercoats?

  6. Rocky Shore Habitat What are the factors that affect the distribution of an organism on the rocky shore?

  7. Biotic and Abiotic factors Distinguish between Biotic and Abiotic factors. The biotic factors are the influences that result from the activities of living organisms in the community eg. competition Abiotic (physical factors) are the influences of the non-living part of the community e.g.. Climate

  8. Desiccation Salinity Temperature Abiotic Light Gradient Oxygen Wave crash Aspect Abiotic (physical factors) are the influences of the non-living part of the community e.g.. Climate

  9. Biotic Predators Competition Mates Food Space Light (algae) The biotic factors are the influences that result from the activities of living organisms in the community eg. competition

  10. Abiotic factors - Desiccation Patella vulgata Actinia equina Cancer pagurus

  11. Abiotic factors - Temperature Littorinalittorea Semibalanusbalanoides

  12. Abiotic factors - Salinity changes Asteriasrubens Carcinusmaenas Ulva that was Enteromorpha

  13. Abiotic factors - Exposure

  14. Abiotic factors Abiotic factors - Light 4: Wave Crash

  15. Abiotic factors - Abiotic factors - Oxygen • cold water holds more oxygen than warm water • most intertidal organisms must respire underwater - Slope - Aspect 4: Wave Crash A B c

  16. Biotic factors - Competition Abiotic factors • Space • Mates • Food • Light • Empty shells (hermit crabs) 4: Wave Crash

  17. Biotic factors -Predation Abiotic factors 4: Wave Crash - from marine (offshore and intertidal) predators - from terrestrial predators 9

  18. How does all this affect the Rocky shore at cullercoats?

  19. 5 Avoid rockpools! 1

  20. 1.00 m – X = Y X Y

  21. The Shore Thing • Monitoring abundance of rocky shore species around the UK as potential indicators of climate change. • Species search: • Abundant • Frequent • Rare • Not found

  22. Common green algae Sea lettuce Gutweed Cladophora

  23. Common brown algae Kelp Laminariadigitata Laminaria saccharina Laminaria hyperborea

  24. Common brown algae Saw wrack Bladder wrack Spiral wrack

  25. Common red algae • Dulse Irish Moss Coral weed

  26. Common Animals
