In search of innovation capability and its sources in local government organizations: a critical interpretative synthesis of the literature
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-05)Empirical research has identified a long list of antecedents that promote innovation in local government organizations. However, less is known about how and why diverse antecedents—as well as their interplay—stimulate local government organizations to innovate and create public value. We address this gap through a systematic and critical interpretive synthesis of the empirical literature on innovation ... -
How Many Reindeer? UAV Surveys as an Alternative to Helicopter or Ground Surveys for Estimating Population Abundance in Open Landscapes
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-20)Conservation of wildlife depends on precise and unbiased knowledge on the abundance and distribution of species. It is challenging to choose appropriate methods to obtain a sufficiently high detectability and spatial coverage matching the species characteristics and spatiotemporal use of the landscape. In remote regions, such as in the Arctic, monitoring efforts are often resource-intensive and there ... -

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-07)In 2013, Brucella melitensis biovar 1 was recovered from the stomach contents of a scimitar-horned Oryx - SHO (Oryx dammah) aborted foetus, and from the articular fluid of a sand gazelle (Gazella marica) in a captive wildlife collection near Abu Dhabi, United Arab Emirates. Other evidence of exposure to the pathogen was collected through serological testing (Rose Bengal test) and B. melitensis-specific ... -
The effect of temperature on growth performance and aerobic metabolic scope in Arctic charr, Salvelinus alpinus (L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-06)In recent years, Arctic char populations in Iceland have declined and the objective of this experiment was to throw further light on these changes by examining the effect of temperature (5, 9, 13, 17, and 21 °C) on the survival, growth rate, metabolism, and physiological indices of juvenile Arctic charr (initial mean body mass 4.02 ± 0.8 g). Mortality was 60% at 21 °C while at lower temperatures it ... -
Macrozooplankton and micronekton diversity and associated carbon vertical patterns and fluxes under distinct productive conditions around the Kerguelen Islands
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-13)Mesopelagic communities are characterized by a large biomass of diverse macrozooplankton and micronekton (MM) performing diel vertical migration (DVM) connecting the surface to the deeper ocean and contributing to biogeochemical fluxes. In the Southern Ocean, a prominent High Nutrient Low Chlorophyll (HNLC) and low carbon export region, the contribution of MM to the vertical carbon flux of the ... -
Impacts of Nile tilapia cage culture on water and bottom sediment quality: The ability of an eutrophic lake to absorb and dilute perturbations
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-07)Environmentally sustainable aquaculture depends on accurate understanding of the impacts of aquaculture-derived organic matter (AOM) and the ability of aquaculture systems to absorb and dilute perturbations. To this end, the present study assessed the impacts of AOM from cage culture of Nile tilapia on the ecology of Lake Victoria, Kenya, using fish cages near Anyanga Beach in Siaya County from ... -
Mucosal Environment Induces Phage Susceptibility in Streptococcus mutans
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-19)Pathogenic bacteria are attracted toward mucosa, as it is their way of entry into the body. However, we know surprisingly little about the phage-bacterium interactions in the mucosal environment. Here, we explored the effect of the mucosal environment on growth characteristics and phage-bacterium interactions in Streptococcus mutans, a causative agent of dental caries. We found that although mucin ... -
Global Patterns and Controls of Nutrient Immobilization on Decomposing Cellulose in Riverine Ecosystems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-18)Microbes play a critical role in plant litter decomposition and influence the fate of carbon in rivers and riparian zones. When decomposing low-nutrient plant litter, microbes acquire nitrogen (N) and phosphorus (P) from the environment (i.e., nutrient immobilization), and this process is potentially sensitive to nutrient loading and changing climate. Nonetheless, environmental controls on immobilization ... -

Global maps of soil temperature
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-29)Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and bioclimatic ... -
