Competition and coexistence among short-grass grazers in the Hluhluwe-iMfolozi Park, South Africa

摘要: Coexistence among grazing ungulates has been related to differences in grass height and grassland types selected, underlain by morphological distinctions. Nevertheless, resource competition may arise when smaller species depress below that suitable for larger species, whereas be counteracted facilitation increase the extent of high-quality available. We investigated resource-use overlap between white rhinoceros (Ceratotherium simum (Burchell, 1817)), blue wildebeest (Connochaetes taurinus 1823)), Burchell’s zebra (Equus burchelli (Gray, 1824)) Hluhluwe-iMfolozi Park South Africa. recorded type favoured, utilized, grazed, greenness selected during dry seasons 2 years. Blue shifted their away from lawn drier year, favoured only relatively wet year. White concentrated fe...
