The population dynamics of the estuarine isopod Exosphaeroma hylocoetes (Barnard, 1940) within three temporarily open/closed southern African estuaries
Item type: Journal Article • Journal: African Zoology • Authors: T.O. Henninger [AN0001] P.W Froneman --- Department of Zoology and Entomology, South Africa A.N. Hodgson --- Department of Zoology and Entomology, South AfricaThe population dynamics of the estuarine isopod, Exosphaeroma hylocoetes, was investigated monthly from February 2006 to August 2007 in three temporarily open/closed Eastern Cape estuaries, the East and West Kleinemonde and Kasouga Estuaries. Mean isopod abundances and biomasses ranged between... -
Growth and longevity of Exosphaeroma hylocoetes (Isopoda) under varying conditions of salinity and temperature

Intertidal foraging by Tristan Thrushes
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Peter G Ryan --- FitzPatrick Institute of African Ornithology, DST-NRF Centre of Excellence, South Africa Ben J Dilley --- FitzPatrick Institute of African Ornithology, DST-NRF Centre of Excellence, South AfricaWe report that some 10% of Tristan Thrushes Turdus eremita on the coast at Inaccessible Island feed extensively on marine invertebrates (mainly crustaceans), despite lacking functional salt glands. Such birds regularly drink from freshwater springs that are common along the... -
