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 ...
A screening for canine distemper virus, canine adenovirus and carnivore protoparvoviruses in Arctic foxes (Vulpes lagopus) and red foxes (Vulpes vulpes) from Arctic and sub-Arctic regions of Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-26)
Canine distemper virus (CDV), canine adenovirus (CAdV) and canine parvovirus type 2 (CPV-2) cause disease in dogs (Canis familiaris). These, or closely related viruses, may also infect wild carnivores. The aim of this study was to investigate exposure to CDV, CAdV and CPV-2 among fox populations in Norway. Arctic foxes (n = 178) from High-Arctic Svalbard were investigated for antibodies against CDV. ...
