Contrasting demographic histories revealed in two invasive populations of the dry rot fungus Serpula lacrymans
(Journal article; Peer reviewed, 2021)Globalization and international trade have impacted organisms around the world leading to a considerable number of species establishing in new geographic areas. Many organisms have taken advantage of human-made environments, ... -
Contrasting Growth Response of Evergreen and Deciduous Arctic-Alpine Shrub Species to Climate Variability
(Journal article; Peer reviewed, 2021)Broad-scale changes in arctic-alpine vegetation and their global effects have long been recognized and labeled one of the clearest examples of the terrestrial impacts of climate change. Arctic-alpine dwarf shrubs are a key ... -
Contrasting northern and southern European winter climate trends during the Last Interglacial
(Peer reviewed; Journal article, 2021)The Last Interglacial (LIG; 130–115 ka) is an important test bed for climate science as an instance of significantly warmer than preindustrial global temperatures. However, LIG climate patterns remain poorly resolved, ... -
Contribution of camera-trapping to the knowledge of Abrocoma boliviensis
(Peer reviewed; Journal article, 2020)Rare and endemic rodent species, such as the critically endangered Bolivian chinchilla rat, Abrocoma boliviensis, are infrequently captured using traditional trapping methods. Therefore, to determine their presence and ... -
Correcting for enzyme immunoassay changes in long term monitoring studies
(Peer reviewed; Journal article, 2021)Enzyme immunoassays (EIAs) are a common tool for measuring steroid hormones in wildlife due to their low cost, commercial availability, and rapid results. Testing technologies improve continuously, sometimes requiring ... -
Cosmogenic exposure dating (36Cl) of landforms on Jan Mayen, North Atlantic, and the effects of bedrock formation age assumptions on 36Cl ages
(Peer reviewed; Journal article, 2021)Jan Mayen is a small volcanic island situated 550 km north of Iceland. Glacial sediments and landforms are relatively common on the island but, so far, only a few of them have been dated. In this study, we present and ... -
Couch potatoes do better: Delayed dispersal and territory size affect the duration of territory occupancy in a monogamous mammal
(Journal article; Peer reviewed, 2017)In territorial, socially monogamous species, the establishment and defense of a terri - tory are an important strategy to maximize individual fitness, but the factors responsi - ble for the duration of territory occupancy ... -
Coupling of VAMPERS within iLOVECLIM: experiments during the LGM and Last Deglaciation
(Journal article; Peer reviewed, 2019)The VAMPERS (Vrije Universiteit Amsterdam Permafrost Snow Model) has been coupled within iLOVECLIM, an earth system model. This advancement allows the thermal coupling between permafrost and climate to be examined from a ... -
Current distribution, status and patterns of spread of the Eurasian beaver Castor fiber, and the implications for management
(Conference report, 2000)Reduced to 1200 animals in 8 small refugia by the end of the 19th century, natural spread and reintroductions have led to a powerful recovery in Eurasian beaver (Castor fiber L. 1758) range and populations. The minimum ... -
Data set on sedimentology, palaeoecology and chronology of Middle to Late Pleistocene deposits on the Taimyr Peninsula, Arctic Russia
(Peer reviewed; Journal article, 2019)This Data in Brief paper contains data (including images) from Quaternary sedimentary successions investigated along the Bol'shaya Balakhnya River and the Luktakh–Upper Taimyra–Logata river system on southern Taimyr ... -
Dataset from long-term air quality monitoring in the World Natural Heritage Geirangerfjord, Western Norway (AQM-G)
(Peer reviewed; Journal article, 2023)Here, we present a datapaper containing observational air quality and meteorological data related to our long-term air quality monitoring program at the UNESCO Natural World Heritage Site Geirangerfjord, Western Norway. ... -
Dendrometer Measurements of Arctic-Alpine Dwarf Shrubs and Micro-Environmental Drivers of Plant Growth - Dataset from Long-Term Alpine Ecosystem Research in Central Norway (LTAER-NO)
(Journal article; Peer reviewed, 2021)Here, we present fine-scale measurements of stem diameter variation from three common arctic-alpine dwarf-shrub species monitored in two mountain regions of Central Norway. All three species (Betula nana, Empetrum nigrum ... -
Detection of Candidatus Neoehrlichia mikurensis in Norway up to the northern limit of Ixodes ricinus distribution using a novel real time PCR test targeting the groEL gene
(Journal article; Peer reviewed, 2019)Background Candidatus Neoehrlichia mikurensis is an emerging tick-borne pathogen. It is widely distributed in Ixodes ricinus ticks in Europe, but knowledge of its distribution in Norway, where I. ricinus reaches its ... -
Detection of tick-borne pathogens by molecular methods
(Journal article; Peer reviewed, 2008)The use of molecular methods such as species-specific PCR, Multiplex-PCR, RT-PCR, reverse line blot hybridisation in investigations of tick-borne pathogens allowed to detect and identify the causative agents of Lyme ... -
Determinants of lifetime reproduction in female brown bears: early body mass, longevity, and hunting regulations
(Journal article; Peer reviewed, 2013)In iteroparous mammals, conditions experienced early in life may have long‐lasting effects on lifetime reproductive success. Human‐induced mortality is also an important demographic factor in many populations of large ... -
Development and evaluation of 16 new microsatellite loci for the rock ptarmigan (Lagopus muta) and cross-species amplification for the willow grouse (L. lagopus)
(Journal article; Peer reviewed, 2018)Abstract The genetic markers designed for this study can facilitate future genetic studies on the rock ptarmigan (Lagopus muta). To our knowledge no microsatellite markers have ever been developed specifically for this ... -
Differences in the vertical distribution pattern of Betula pubescens in Norway and its ecological significance
(Chapter; Peer reviewed, 1996)Several factors influence the altitudinal position of the climatic forest-limit. In addition to variations due to different "forest-limit" definitions, topographic factors are very important. In Western Norway, a range of ... -
Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites
(Peer reviewed; Journal article, 2022)1. The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy ... -
