“…Previous work has demonstrated the importance of redundancy with different groups of organism and in distinct ecosystems such as South African fynbos (Cowling et al 1994), grasslands (Johnson and Mayeux 1992, DeBello et al 2009), micro‐organisms (Wohl et al 2004, Jiang 2007, Ayres et al 2009) soil invertebrates (Cole et al 2006, Davidson and Grieve 2006, Ganin 2006), stream invertebrates (Bêche and Statzner 2009) and seagrass beds (Duffy et al 2001). However, studies have failed to find redundancy, for instance, in avian assemblages (Petchey et al 2007), and coastal marine assemblages (Micheli and Halpern 2005).…”
