Ungulate population monitoring in an open tundra landscape: distance sampling versus total counts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-07-27)
Researchers and wildlife managers strive for low bias and high precision (i.e. high accuracy) when estimating animal population sizes. Distance sampling is currently one of the most widely used monitoring methods. However, it relies on strict sampling designs and modeling assumptions that can be difficult to meet in the field. Here, we use data from two sub-populations of non-migratory wild Svalbard ...
Climate Events Synchronize the Dynamics of a Resident Vertebrate Community in the High Arctic
(Peer reviewed; Research report; Forskningsrapport, 2013-01-18)
Recently accumulated evidence has documented a climate impact on the demography and dynamics of single species, yet the impact at the community level is poorly understood. Here, we show that in Svalbard in the high Arctic, extreme weather events synchronize population fluctuations across an entire community of resident vertebrate herbivores and cause lagged correlations with the secondary consumer, ...
