Assessing the usefulness of citizen science data for habitat suitability modelling: Opportunistic reporting versus sampling based on a systematic protocol
(Peer reviewed; Journal article, 2020)Aim: To evaluate the potential of models based on opportunistic reporting (OR) compared to models based on data from a systematic protocol (SP) for modelling species distributions. We compared model performance for eight ... -
An assessment of relative habitat use as a metric for species’ habitat association and degree of specialization
(Peer reviewed; Journal article, 2021)In order to understand species’ sensitivity to habitat change, we must correctly determine if a species is associated with a habitat or not, and if it is associated, its degree of specialization for that habitat. However, ... -
An assessment of silvopastoral systems condition and their capacity to generate ecosystem services in the Colombian Amazon

Association of landscape and environmental variables with the recruitment of the freshwater pearl mussel (Margaritifera margaritifera) in Norway
(Peer reviewed; Journal article, 2023)Using data from 309 localities with freshwater pearl mussel, Margaritifera margaritifera, in Norway, we analyzed the effect of several landscape and environmental variables on this species’ recruitment. Median summer air ... -
At which spatial and temporal scales can fungi indicate habitat connectivity?
(Journal article; Peer reviewed, 2018)Isolation of habitats in space and time affects species globally and in a multitude of ecosystems. It is however often difficult to assess the level of isolation from the point of view of the focal species. Indicator species ... -
