SMALL‐RODENT DYNAMICS AND PREDATION
TLDR
The predation hypothesis is reviewed and it is considered it unlikely that the phenotypic and genotypic composition of pop- ulations would be instrumental for generating the broad patterns in rodent oscillations, which may have some population-dynamic consequences.
The Puzzles of Population Cycles and Outbreaks of Small Mammals Solved?
TLDR
This work synthesizes the recent knowledge of three key aspects of these animals' population cyles: periodicity, amplitude, and spatiotemporal synchrony; (2) reproduction and survival; and (3) underlying mechanisms.
Population oscillations of boreal rodents: regulation by mustelid predators leads to chaos
TLDR
The results suggest that the multiannual oscillations of rodent populations in Fennoscandia are due to delayed density dependence imposed by mustelid predators, and are chaotic.
Numerical and Functional Responses of Kestrels, Short‐Eared Owls, and Long‐Eared Owls to Vole Densities
TLDR
The pooled functional response curve of these three raptor species to the fluctuating densities of Microtus spp.
The Boreal Owl: Ecology, Behaviour and Conservation of a Forest-Dwelling Predator
TLDR
The authors study the complex interactions of Boreal Owls with their prey species, and examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually.
Inter-sexual differences in the immune response of Eurasian kestrel nestlings under food shortage
TLDR
Male chicks exhibited lower cell-mediated immunity assessed by a cutaneous hypersensitivity response than females, but only in treatments suffering from food restrictions, as indicated by chick starvation, revealing inter-sexual differences in physiological strategies in early life.
Specialist and generalist natural enemies as an explanation for geographical gradients in population cycles of northern herbivores
TLDR
It is concluded that the specialist/generalist predation hypothesis offers a common explanation for the population cycles and their geographical gradients irrespective of whether a herbivorous insect or small mammals are concerned.
Alien predators are more dangerous than native predators to prey populations
TLDR
The results demonstrate that introduced predators can impose more intense suppression on remnant populations of native species and hold them further from their predator-free densities than do native predators preying upon coexisting prey.
Predator manipulation experiments: impacts on populations of terrestrial vertebrate prey
TLDR
The results show that predation indeed limits prey populations, as prey densities change substantially after predator manipulations, and positive impacts of predator manipulation appeared to increase with duration of the experiment for non-cyclic prey, while the opposite was true for cyclic prey.
FOOD LIMITATION ON BROOD SIZE: EXPERIMENTAL EVIDENCE IN THE EURASIAN KESTREL
TLDR
While females adjusted parental effort to male provisioning and offspring requirements, males did not change parental- effort within a season, suggesting that male parental effort is fixed at a level where male survival is not jeopardized.
