Ecol Lett 9:410-8. 2006..Another process was operating to drive the populations down. Together with our other results these findings emphasize that both trophic and intrinsic processes may act within populations to cause unstable dynamics... - Sacred cows and sympathetic squirrels: the importance of biological diversity to human healthAndy Dobson

Int J Parasitol 35:367-73. 2005..retortaeformis and the significant negative effect of intensity of infection on body condition are in accordance with the hypothesis that the host-parasite interaction is the causative destabilising mechanism for mountain hare dynamics... - Competition and mutualism among the gut helminths of a mammalian hostJoanne Lello

Pathogen interactions, population cycles, and phase shiftsJoanne Lello
School of Biosciences, Cardiff University, Cardiff CF10 3TL, Wales, UK
Am Nat 171:176-82. 2008..Finally, because the model structure used here is analogous to models of a simple predator-prey system, we also consider the consequences of these findings in the context of that system...- Analysing noisy time-series: describing regional variation in the cyclic dynamics of red grouseDaniel T Haydon
