Seasonal difference in temporal transferability of an ecological model: near-term predictions of lemming outbreak abundances
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-15)
Ecological models have been criticized for a lack of validation of their temporal transferability. Here we
answer this call by investigating the temporal transferability of a dynamic state-space model developed
to estimate season-dependent biotic and climatic predictors of spatial variability in outbreak abundance
of the Norwegian lemming. Modelled summer and winter dynamics parametrized by spatial ...
Transferability of biotic interactions: temporal consistency of arctic plant-rodent relationships is poor
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-17)
Variability in biotic interaction strength is an integral part of food web functioning.
However, the consequences of the spatial and temporal variability of biotic interactions
are poorly known, in particular for predicting species abundance and distribution.
The amplitude of rodent population cycles (i.e., peak-phase abundances) has
been hypothesized to be determined by vegetation properties ...
