Rocky Shores: Life on the Edge

Synopsis: A tour of rocky shores in Pembrokeshire, showing the rich diversity of plants (mainly algae) and animals (mainly barnacles and limpets) present in the intertidal zone. Shows the broad horizontal bands (zonation) in which the organisms are to be found, and in any one area there is vigorous competition for space on the rocks. Seaweeds such as wracks exploit every possible rock foundation and create safe areas for animals to shelter within their fronds. But animals such as limpets are voracious predators of young algae and control the seaweed spread. The plant and animal life forms a naturally zoned community in which every organism is balanced on the edge of life waiting for fresh supplies of food on each tide.

At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
