| influence of geographical scale on the detection of density dependence in the host-parasite system, arvicola terrestris and taenia taeniaeformis. | infection by the cestode taenia taeniaeformis was investigated within numerous cyclic populations of the fossorial water vole arvicola terrestris sampled during 4 years in franche-comté (france). the relative influence of different rodent demographic parameters on the presence of this cestode was assessed by considering (1) the demographic phase of the cycle; (2) density at the local geographical scale (<0.1 km2); (3) mean density at a larger scale (>10 km2). the local scale corresponded to the ... | 2006 | 16329763 |
