Haddad, Charles R.; Foord, Stefan Hendrik; Fourie, Rene; Dippenaar-Schoeman, Anna S. (Anna Sophia), 1948- (Taylor and Francis and NISC (Pty) Ltd, 2015-12)Fire is widely used as a management strategy in grasslands to maintain vegetation structure and improve grazing quality for large herbivores. The impacts of burning on invertebrates in South Africa remain poorly understood. ...

Foord, Stefan Hendrik; Dippenaar-Schoeman, Anna S. (Anna Sophia), 1948-; Haddad, Charles R. (Taylor & Francis, 2011-11)Invertebrates include more than 80% of all animals, yet they are severely under-represented in studies of southern African diversity. Site biodiversity estimates that ignore invertebrates, not only omit the greatest part ...
