Numerical and Functional Responses of Kestrels, Short‐Eared Owls, and Long‐Eared Owls to Vole Densities
We studied numerical and functional responses of breeding European Kes- trels (EK) (Falco tinnunculus), Short-eared Owls (SO) (Asio flammeus), and Long-eared Owls (LO) (Asio otus) during 1977-1987 inExpand

Responses of stoats and least weasels to fluctuating food abundances: is the low phase of the vole cycle due to mustelid predation?
SummaryWe studied responses of stoats and least weasels to fluctuating vole abundances during seven winters in western Finland. Density indices of mustelids were derived from snow-tracking, dietExpand

DOES MOBILITY OR SEX OF VOLES AFFECT RISK OF PREDATION BY MAMMALIAN PREDATORS
Animals gain fitness benefits if they can increase their survival prospects by reducing mobility under temporarily high predation risk. We used miniature radio collars to determine whether mobilityExpand

Predator–induced synchrony in population oscillations of coexisting small mammal species
Comprehensive analyses of long–term (1977–2003) small–mammal abundance data from western Finland showed that populations of Microtus voles (field voles M. agrestis and sibling voles M.Expand

Experimental tests of predation and food hypotheses for population cycles of voles
Pronounced population cycles are characteristic of many herbivorous small mammals in northern latitudes. Although delayed density–dependent effects of predation and food shortage are often proposedExpand

Variation in the diet composition of a generalist predator, the red fox, in relation to season and density of main prey
Abstract Diet composition of a generalist predator, the red fox ( Vulpes vulpes ) in relation to season (winter or summer) and abundance of multi-annually cyclic voles was studied in western FinlandExpand

Experimental reduction of predators reverses the crash phase of small-rodent cycles
The mechanisms driving short-term (3–5 yr) cyclic fluctuations in densities of boreal small rodents, and especially, those causing a crash in numbers, have remained a puzzle, although food shortageExpand

Vole cycles and predation in temperate and boreal zones of Europe
Summary 1. Graham & Lambin (2002) have reported on a weasel-reduction experiment, concluding that the impact of weasel predation on field vole survival was neither sufficient nor necessary toExpand

WINTER FOOD SUPPLY LIMITS GROWTH OF NORTHERN VOLE POPULATIONS IN THE ABSENCE OF PREDATION
Mathematical models have suggested that population cycles of northern voles are generated by a combined effect of delayed and direct density-dependent mechanisms. Predation is considered to be theExpand

Dynamic effects of predators on cyclic voles: field experimentation and model extrapolation
Mechanisms generating the well-known 3–5 year cyclic fluctuations in densities of northern small rodents (voles and lemmings) have remained an ecological puzzle for decades. The hypothesis that theseExpand
