I studied predator-prey relationships between goshawk Accipiter gentilis and four species of forest grouse (Tetraonidae) in northern Finland during 1988–1998. The main purpose of my study was to evaluate the impact of goshawk predation and its possible effect on multiannual cycling patterns in grouse numbers. Theoretically specialist predators should tend to cause stable-limit cycles in prey populations if there is a time-lag in the predator's response to prey density and the prey species… Expand
Coupling in goshawk and grouse population dynamics in Finland
TLDR
This study studies the population dynamics of a predator–prey setting in Finland by fitting first-order log-linear vector autoregressive models to long-term count data from active breeding sites of the northern goshawk and three of its main prey species, which belong to the same forest grouse guild and show synchronous fluctuations. Expand
Delayed numerical response of goshawks to population fluctuations of forest grouse
TLDR
In northern Europe with few alternative preys, goshawk predation might contribute to the generation of multiannual cycles of forest grouse, and this should be tested experimentally. Expand
The role of forest maturation in causing the decline of Black Grouse Tetrao tetrix
TLDR
Analysis of the change in Black Grouse abundance within 1.5 km of discrete forest blocks suggests that forest maturation, which has been the dominant habitat change during the course of the study, alone accounts for 58–78% of the decline. Expand
What Explains Forest GrouseMortality : Predation Impacts of Raptors , Vole Abundance , orWeather Conditions ?
We investigated predation rates of black grouse chicks during 1985–2007 in two localities in western Finland in light of three predation hypothesis: The Alternative Prey Hypothesis (APH) stating thatExpand
Numerical response of common buzzards and predation rate of main and alternative prey under fluctuating food conditions
TLDR
The results appear to support APH rather than SPH and indicate that predation by buzzards may dampen population cycles of main prey (voles) but amplify population fluctuations of grouse. Expand
Intraguild predation and competition impacts on a subordinate predator
TLDR
It is concluded that the common buzzard needs to balance the risks of IG predation and interference competition with the availability of its own resources, and the presence of other predators associated with high food levels may impede a subordinate predator taking full advantage of the available food. Expand
Landscape and season effects on the diet of the Goshawk.
TLDR
The final outcome of these landscape-related predator–prey interactions is likely to depend on direct functional and numerical responses of predators to the variation in the abundance and vulnerability of the main and alternative prey, as well as on the indirect controlling effect of top predators on smaller predators and nest predators. Expand
What Explains Forest Grouse Mortality: Predation Impacts of Raptors, Vole Abundance, or Weather Conditions?
TLDR
It is concluded that the among-year survival pattern of juvenile forest grouse may largely be determined by raptor predation, with some support for APH. Expand
Seasonal survival of young and adult black grouse females in boreal forests
TLDR
A clear difference in the survival of young and older females during late winter, a decrease in female survival during spring, and variation between the study years are shown. Expand
Effects of forest characteristics on ruffed grouse nesting ecology in central Maine, USA
TLDR
The results demonstrate the importance of forest characteristics on multiple components of species' nesting ecology, and management suggestions to promote attractive ruffed grouse nesting habitat while potentially mitigating sources of nesting failure are provided. Expand

Goshawk predation during winter, spring and summer in a boreal forest area of central Sweden
TLDR
The high proportion of squirrel in the winterdiet, as compared to the breeding season, is believed to be due to squirrels having to accept an increased predation risk in winter, in order to feed efficiently enough. Expand
Survival, ranging, habitat choice and diet of the Northern Goshawk Accipiter gentilis during winter in Northern Finland
TLDR
The winter ecology of the Northern Goshawk Accipiter gentilis was studied in northern Finland in 1991-95, implying better food availability there compared with woodland areas and some Goshawks preyed upon animals living in the city dump in late winter. Expand
Breeding success of black grouse and capercaillie in relation to mammalian predator densities on two spatial scales
TLDR
The results support the hypothesis that higher generalist predator densities are responsible for lower breeding success of forest dwelling grouse moving southwards in Fennoscandia and suggest that the stoat is of minor importance as nest apd brood predator compared to red fox and pine marten. Expand
Raptor predation and population limitation in red grouse
TLDR
A model suggested that raptor predation prevented the grouse population from increasing and was thus a limiting factor. Expand
Sexual and seasonal differences in mortality of the black grouse Tetrao tetrix in boreal Sweden
Sexual and seasonal differences in mortality in the Black Grouse Tetrao tetrix L. were studied by radio-tracking 53 hens for 3051 bird-days in spring and summer, and 54 cocks for 3906 birds-daysExpand
Detection of forest grouse by mammalian predators: A possible explanation for high brood losses in fragmented landscapes
TLDR
As young broods concentrate in highly restricted habitats, the predator gain of searching for broods increases exponentially with the loss of brood habitat, whereas it decreases linearly with increasing nest predation. Expand
Numerical and functional responses in generalist predators: hen harriers and peregrines on Scottish grouse moors
TLDR
In the absence of persecution, the impact of harriers on grouse populations is most likely to be greatest on moors where alternative prey and thus harriers are abundant, and the question of whether harriers may dampen grouse population cycles at low grouse density is discussed. Expand
Predation of Tengmalm's Owls: Numerical Responses, Functional Responses and Dampening Impact on Population Fluctuations of Microtines
TLDR
The predation impact on microtines was positively dependent on vole densities and suggests that the owls dampen microtine cycles, and the following factors seemed to promote the dampening impact. Expand
Female age and breeding performance in a cyclic population of black grouse Tetrao tetrix
TLDR
The breeding performance in yearling and adult female black grouse Tetrao tetrix was studied in a 6–7 year cyclic population during 1989–93 in central Finland and adults were larger, had more body mass at capture, initiated laying earlier and had larger eggs and clutches than yearlings. Expand
Great Horned Owls and Snowshoe Hares: What Causes the Time Lag in the Numerical Response of Predators to Cyclic Prey?
TLDR
A mechanism based on individual behaviour to explain delayed numerical responses is proposed : territorial predators monopolize a disproportionately large amount of resources for reproduction during the increase and peak of the cycle, and are then buffered against prey declines by adjusting their breeding activities.
