2. School of Marine Science and Technology

3. Aims for today 1.What are the factors that affect the distribution of an organism on the rocky shore? 2.How have the organisms become adapted to the rocky shore? 3.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. Marine habitats Polar oceans Coral reef Rocky Shores Open oceans Deep sea 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 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 Distinguish between Biotic and Abiotic factors.

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

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

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

11. Abiotic factors - Temperature Littorina littoreaSemibalanus balanoides

12. Abiotic factors - Salinity changes Asterias rubensCarcinus maenas Ulva that was Enteromorpha

13. Abiotic factors - Exposure

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

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

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

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

19. 5 1 Avoid rockpools!

20. Y X 1.00 m – 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
