From individuals to population cycles: the role of extrinsic and intrinsic factors in rodent populations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-28)Rodent population cycles have fascinated scientists for a long time. Among various hypotheses, an interaction of an extrinsic factor (predation) with intrinsic factors (e.g., sociality and dispersal) was suggested to lead to the generation of population cycles. Here, we tested this hypothesis with an individual-based model fully parameterized with an exceptionally rich empirical database on vole ... -
Local and regional determinants of colonisation-extinction dynamics of a riparian mainland-island root vole metapopulation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)The role of local habitat geometry (habitat area and isolation) in predicting species distribution has become an increasingly more important issue, because habitat loss and fragmentation cause species range contraction and extinction. However, it has also become clear that other factors, in particular regional factors (environmental stochasticity and regional population dynamics), should be taken ... -
Why do the boreal forest ecosystems of Northwestern Europe differ from those of Western North America?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-20)The boreal forest is one of the largest terrestrial biomes on Earth. Conifers normally dominate the tree layer across the biome, but other aspects of ecosystem structure and dynamics vary geographically. The cause of the conspicuous differences in the understory vegetation and the herbivore–predator cycles between northwestern Europe and western North America presents an enigma. Ericaceous dwarf ...
