Copyright Royal Entomological Society, 2005 KEYWORDS Angle • individual-based models • intraspecific • introduction • invasion • male–male • Orthoptera • stridulation • Tettigoniidae ABSTRACTAbstract. 1. Individual movement behaviours of male Roesel's bush crickets were compared between individuals experimentally released with or without conspecifics. 2. Differences in movement behaviour were recorded between the groups, with individuals released with conspecifics moving faster and further. 3. The study shows that behavioural interactions between individuals need to be considered in population modelling. Empirical movement data derived from lone individuals would result in a significant underestimation of both population expansion (−38.1%) and inter-patch movement (−35.8%). Accepted 26 August 2004 |
