“…These methods have several weaknesses (Kennedy, 1995b, c), and the more recent studies have developed means to minimize their effects, but they have been useful for assessing the likely responses of the indigenous biota to climate change. The use of screens has led to spectacular responses in the growth of microbial groups, bryophytes and higher plants (Smith, 1990(Smith, , 1994WynnWilliams, 1993WynnWilliams, , 1996Kennedy, 1996). Fewer studies have been directed at faunal communities, but some arthropod populations have expanded rapidly (Kennedy, 1994), and trophic groups of soil nematodes have responded differently (Convey & Wynn-Williams, 2002;.…”
