10Be surface exposure dating of the deglaciation of northernmost Norway and Finland
(Peer reviewed; Journal article, 2020)During the Last Glacial Maximum, the coast of Finnmark county, northern Norway, was covered by the Scandinavian Ice Sheet (SIS), which coalesced with the Barents Sea Ice Sheet (BSIS) off the coast. The region is thus ... -
A "clearcut" case? Brown bear selection of coarse woody debris and carpenter ants on clearcuts
(Journal article; Peer reviewed, 2015-07-05)Forest management alters habitat characteristics, resulting in various effects among and within species. It is crucial to understand how habitat alteration through forest management (e.g. clearcutting) affects animal ... -
A gross assessment of the suitability of selected Scottish riparian habitats for beaver
(Journal article; Peer reviewed, 2000)In November 1998 we were shown a selection of riparian habitats in Scotland and asked to assess their suitability for beaver based on our experience in working with beaver elsewhere. Though many examples of good beaver ... -
A human-induced landscape of fear influences foraging behavior of brown bears
(Journal article; Peer reviewed, 2018)Animals adapt their foraging behavior to variations in food availability and predation risk. In Sweden, brown bears (Ursus arctos) depend on a nearly continuous intake of berries, especially bilberries (Vaccinium myrtillus) ... -
A spherical-plot solution to linking acceleration metrics with animal performance, state, behaviour and lifestyle
(Journal article; Peer reviewed, 2016)Background: We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from ... -
A test of the dear enemy phenomenon in the Eurasian beaver
(Journal article; Peer reviewed, 2002)We tested the hypothesis that Eurasian beavers, Castor fiber, display the dear enemy phenomenon; that is, they respond less aggressively to intrusions by their territorial neighbours than intrusions by nonterritorial ... -
Abrupt high-latitude climate events and decoupled seasonal trends during the Eemian
(Journal article; Peer reviewed, 2018)The Eemian (the Last Interglacial; ca. 129–116 thousand years ago) presents a testbed for assessing environmental responses and climate feedbacks under warmer-than-present boundary conditions. However, climate syntheses ... -
Aerobic and anaerobic speed predicts 800-m running performance in young recreational runners
(Peer reviewed; Journal article, 2021)The main aim was to investigate the impact of maximal aerobic speed (MAS), maximal anaerobic speed (MANS), and time to exhaustion (TTE) at 130% MAS, on 800-m running time performance (800TT). A second aim was to investigate ... -
Age-related changes in somatic condition and reproduction in the Eurasian beaver: Resource history influences onset of reproductive senescence
(Journal article; Peer reviewed, 2017)Using 15 years of data from a stable population of wild Eurasian beavers (Castor fiber), we examine how annual and lifetime access to food resources affect individual age-related changes in reproduction and somatic condition. ... -
Agreement between reconstructed and modeled boreal precipitation of the Last Interglacial
(Journal article; Peer reviewed, 2019)The last extended time period when climate may have been warmer than today was during the Last Interglacial (LIG; ca. 129 to 120 thousand years ago). However, a global view of LIG precipitation is lacking. Here, seven new ... -
Agricultural landscapes and the Loire River influence the genetic structure of the marbled newt in Western France
(Journal article; Peer reviewed, 2018)Amphibians are particularly sensitive to landscape fragmentation. Potential barriers between breeding sites can negatively infuence the dispersal of individuals and increase genetic structure between populations. In this ... -
An In Situ Experimental Study of Effects on Submerged Vegetation After Activated Carbon Amendment of Legacy Contaminated Sediments
(Journal article; Peer reviewed, 2018)Activated carbon (AC) amendment has been shown to reduce bioavailability of hydrophobic contaminants in the bioactive layer of sediment. Unwanted secondary effects of AC amendment could be particularly undesirable for ... -
Analysis of DNA polymorphism in wild populations of herb-Paris (Paris quadrifolia L., Trilliaceae) from Lithuania and Norway.
(Journal article; Peer reviewed, 2006)Analysis of random amplified polymorphic DNA (RAPD) was used to determine genetic diversity within the populations of herb-Paris plant from Lithuania and Norway. RAPD analyses have shown 21.9 ± 5.2% of polymorphic loci in ... -
Anaplasma in ticks feeding on migrating birds and questing ticks in Lithuania and Norway

Aquatic habitat use in a semi-aquatic mammal: the Eurasian beaver
(Peer reviewed; Journal article, 2021)Background: Semi-aquatic mammals exploit resources both on land and in water and may require both to meet their habitat requirements including food- and building resources, refuges, and for social interactions with ... -
Are trampling effects by wild tundra reindeer understudied?
(Journal article; Peer reviewed, 2018)Grazing and trampling by the wide-ranging wild tundra reindeer may have major top down landscape effects by causing vegetation changes. Grazing, as the collective effect of eating, trampling, defecation, and urination, has ... -
Are trends in Olive Ridley sea turtle (Lepidochelys olivacea) nesting abundance affected by El Niño Southern Oscillation (ENSO) variability? Sixteen years of monitoring on the Pacific coast of northern Central America
(Peer reviewed; Journal article, 2020)Long-term monitoring is essential for the identification of population trends, and to understand how these trends are affected by climate variability. The El Niño Southern Oscillation (ENSO) is the strongest global interannual ... -
Atmospheric circulation over Europe during the Younger Dryas
(Peer reviewed; Journal article, 2020)The Younger Dryas (YD) was a period of rapid climate cooling that occurred at the end of the last glaciation. Here, we present the first palaeoglacier-derived reconstruction of YD precipitation across Europe, determined ... -
Bears and berries: species-specific selective foraging on a patchily distributed food resource in a human-altered landscape
(Journal article; Peer reviewed, 2016)When animals are faced with extraordinary energyconsuming events, like hibernation, finding abundant, energy-rich food resources becomes particularly important. The profitability of food resources can vary spatially, ... -
Beaver (Castor fiber) activity and spatial movement in response to light and weather conditions
(Peer reviewed; Journal article, 2020)Animal behaviour can affect individual fitness and is influenced by exogenous and endogenous factors. Here, we investigated how light (daylight length and moonlight), weather (precipitation and temperature), age, sex and ...
