Richard Barnes is a marine biologist who works with the relevant National Parks authorities in South Africa, Australia and (until recently) Indonesia, Seychelles and the UK, on estuarine, lagoonal and semi-enclosed marine bay habitats within their jurisdiction.  His specific research area revolves around how and why benthic invertebrate biodiversity varies across relatively small-scale space and across microhabitat interfaces in fish nursery areas, and how this impinges – or should impinge – on conservation management strategies and artisanal exploitation, including on the zonation of human activities that usually occurs within such National Parks.  It should perhaps be noted that he is now in the middle tertile of his 70s and hence operates from honorary research staff positions that he holds in various academic institutions in Queensland, South Africa and the UK, around which he rotates each year.
