North Ronaldsay’s native sheep forage seaweed. It’s now been discovered that seaweed in the diet can reduce greenhouse gas emission which helping weight gain. Siân Tarrant, warden of the 13-mile-long stone dyke confining the island sheep to the shore, sets the scene and introduces researchers. Dr Katerina Theodoridou of Queen’s University Belfast shows how dietary seaweed can cut methane and ammonia pollution and reduce soya usage. Dr Jessica Adams of Aberystwyth University describes how micro-organisms from the gut of North Ronaldsay sheep may assist macroalgae degradation for biofuel production. The enzymes involved may have potential for novel technologies and enzymatic cocktails, says Dr Luisa Ciano of Nottingham University.
