Ant semiochemicals limit apterous aphid dispersal
Oliver, T.H.; Mashanova, A.; Leather, S.R.; Cook, J.M.; Jansen, V.A.A. (2007-12-22)Some organisms can manipulate the nervous systems of others or alter their physiology in order to obtain benefit. Ants are known to limit alate aphid dispersal by physically removing wings and also through chemical ... -
Density-dependent dispersal may explain the mid-season crash in some aphid populations
Mashanova, A.; Gange, A.C.; Jansen, V.A.A. (2008-07-01)Aphid population dynamics during the season show a characteristic pattern with rapid increase in numbers at the beginning followed by a sudden drop in the middle of the season. This pattern is usually associated with ... -
Evidence for intermittency and a truncated power law from highly resolved aphid movement data
Mashanova, A.; Oliver, T.H.; Jansen, V.A.A. (2009-06-01)Power laws are increasingly used to describe animal movement. Despite this, the use of power laws has been criticized on both empirical and theoretical grounds, and alternative models based on extensions of conventional ...
