The Ratio between Field Attractive and Background Volatiles Encodes Host-Plant Recognition in a Specialist Moth
(Journal article; Peer reviewed, 2017-12-22)Volatiles emitted by plants convey an array of information through different trophic levels. Animals such as host-seeking herbivores encounter plumes with filaments from both host and non-host plants. While studies showed ... -
The red wood ant Formica aquilonia (Hymenoptera : Formicidae) may affect both local species richness and composition at multiple trophic levels in a boreal forest ecosystem
(Journal article; Peer reviewed, 2018)In temperate forests, red wood ants (Formica aquilonia) are considered ecosystem engineers affecting ecosystem properties and functions. Possible effects of F. aquilonia ants on species communities of invertebrates and ... -
The relationships between biodiversity and ecosystem services and the effects of grazing cessation in semi-natural grasslands
(Journal article; Peer reviewed, 2018-04-13)Land use change can affect biodiversity, and this has an impact on ecosystem services (ESs), but the relationships between biodiversity and ESs are complex and poorly understood. Biodiversity is declining due to the ... -
The role of landscape characteristics for forage maturation and nutritional benefits of migration in red deer
(Journal article; Peer reviewed, 2017-05-12)Large herbivores gain nutritional benefits from following the sequential flush of newly emergent, high-quality forage along environmental gradients in the landscape, termed green wave surfing. Which landscape characteristics ... -
The Social Aspects of Fishing Effort: Technology and Community in Norway’s Blue Whiting Fisheries
(Journal article; Peer reviewed, 2007-01-06)While economic literature inspired by the “tragedy of the commons” has emphasised people’s tendency to increase fishing effort beyond desirable levels, sociologists and anthropologists who have studied the social aspects ... -
Thermal modification of wood—a review: chemical changes and hygroscopicity
(Peer reviewed; Journal article, 2021-01-07)Thermal modification is a well-established commercial technology for improving the dimensional stability and durability of timber. Numerous reviews of thermally modified timber (TMT) are to be found in the scientific ... -
Thinning regimes and initial spacing for Eucalyptus plantations in Brazil
(Journal article; Peer reviewed, 2018)This study focuses on the effects of different thinning regimes on clonal Eucalyptus plantations growth. Four different trials, planted in 1999 and located in Bahia and Espírito Santo States, were used. Aside from thinning, ... -
Three decades of environmental change studies at alpine Finse, Norway: climate trends and responses across ecological scales
(Peer reviewed; Journal article, 2022-11-30)The International Tundra Experiment (ITEX) was established to understand how environmental change impacts Arctic and alpine ecosystems. The success of the ITEX-network has allowed for several important across-site syntheses, ... -
Three new Leptographium spp. (Ophiostomatales) infecting hardwood trees in Norway and Poland
(Journal article; Peer reviewed, 2018-07-06)Species of Leptographium are characterized by mononematous or synnematous conidiophores and are commonly associated with different arthropods. Some of them also produce a sexual state characterised by globose ascomata with ... -
Timber volume estimation based on airborne laser scanning — comparing the use of national forest inventory and forest management inventory data
(Peer reviewed; Journal article, 2021-05-17)Key message Large-scale forest resource maps based on national forest inventory (NFI) data and airborne laser scanning may facilitate synergies between NFIs and forest management inventories (FMIs). A comparison of models ... -
Timeline of autumn phenology in temperate deciduous trees
(Peer reviewed; Journal article, 2020-04-27)Cessation of xylem formation or wood growth (CWG) and onset of foliar senescence (OFS) are key autumn phenological events in temperate deciduous trees. Their timing is fundamental for the development and survival of trees, ... -
Timeliness and traffic intensity in spring fieldwork in Norway: importance of soil physical properties, persistence of soil degradation, and consequences for cereal yield
(Peer reviewed; Journal article, 2020-05-14)Future increase in precipitation in Scandinavia may exacerbate the dilemma of spring fieldwork that farmers have, concerning topsoil compaction versus delayed sowing on autumn ploughed soil. The former may lead to soil ... -
Timing and duration of drought modulate tree growth response in pure and mixed stands of Scots pine and Norway spruce
(Peer reviewed; Journal article, 2022-08-08)1. Climate change is increasing the severity and frequency of droughts around the globe, leading to tree mortality that reduces production and provision of other ecosystem services. Recent studies show that growth of mixed ... -
Timing of the outfield grazing season and finishing of lambs: A whole-farm modelling study of forage-based sheep production systems in Norway
(Peer reviewed; Journal article, 2022-12-30)Norwegian sheep production is based on the use of free outfield grazing resources in the mountains and forests in summer. Lamb prices are strongest at the beginning of the slaughter season in August and then begin to ... -
Tire wear particles concentrations in gully pot sediments
(Peer reviewed; Journal article, 2021-05-15)While tire wear and tear is known to be a major source of microplastics in the environment, its monitoring is still hampered by the lack of analytical methods able to provide concentrations in environmental matrices. ... -
To be or not to be a subspecies: description of Saperda populnea lapponica ssp. n. (Coleoptera, Cerambycidae) developing in downy willow (Salix lapponum L.)
(Journal article; Peer reviewed, 2017-08-17)A new subspecies of the European cerambycid Saperda populnea (Linnaeus, 1758) is described: Saperda populnea lapponica ssp. n. based on specimens from Scandinavia. The male genitalia characters were examined and found to ... -
To what extent is climate change adaptation a novel challenge for agricultural modellers?
