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 ... -
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 ... -
Behavioral correlates of supplementary feeding of wildlife: Can general conclusions be drawn?
(Journal article; Peer reviewed, 2014-10-12)Supplementary feeding is a common, but controversial, tool in wildlife management, because it can benefit both humans and wildlife (e.g., increased wildlife densities), but has certain downsides (e.g., increased disease ... -
Captive care and welfare considerations for beavers
(Journal article; Peer reviewed, 2015-03-01)Beavers (Castor spp.) tend not to be a commonly held species and little published material exists relating to their captive care. We review published material and discuss husbandry issues taking into account the requirements ... -
Echinococcus multilocularis Detection in Live Eurasian Beavers (Castor fiber) Using a Combination of Laparoscopy and Abdominal Ultrasound under Field Conditions
(Journal article; Peer reviewed, 2015-07-15)Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber) may act as a rare intermediate host, and so unscreened wild ... -
Effect of latitude and mountain height on the timberline (Betula pubescens ssp. czerpanovii) elevation along the central Scandinavian mountain range
(Journal article; Peer reviewed, 2015)Previously published isoline maps of Fennoscandian timberlines show that their highest elevations lie in the high mountain areas in central south Norway and from there the limits decrease in all directions. These maps are ... -
Estimation of lichen biomass with emphasis on reindeer winter pastures at Hardangervidda, S Norway
(Journal article; Peer reviewed, 2014)Quantification of lichen abundance is important for management of reindeer populations. We measured dry lichen biomass in 876 micro plots (16.5 cm - 16.5 cm) systematically sampled within 219 vegetation plots (2 m - 2 m) ... -
Importance of mountain height and latitude for the altitudinal distribution limits of vascular plants in Scandinavia: are the mountains high enough?
(Journal article; Peer reviewed, 2010)The main aim of the present paper was to study regional differences in the altitudinal distribution limits of vascular plants in relation to mountain height and latitudinal position. Altitudinal limits from previously ... -
Invasive North American beaver Castor canadensis in Eurasia: a review of potential consequences and a strategy for eradication
(Journal article; Peer reviewed, 2012-12)Seven North American beavers Castor canadensis (Cc) were introduced into Finland in 1937 to supplement an ongoing reintroduction of the nearly extinct Eurasian beaver C. fiber (Cf). At that time, many zoologists recognised ... -
Methods for live-trapping beaver (Castor spp.)
(Journal article; Peer reviewed, 1998)Effective live-trapping of beaver (Castor spp.) has been and will continue to be necessary for introductions, re-introductions, translocation for the preservation of populations, removal of nuisance beaver, and to obtain ... -
The growth and phenology patterns of herb Paris (Paris quadrifolia L., Trilliaceae): relation to soil and air temperatures
(Journal article; Peer reviewed, 2003)The phenology and development of Paris quadrifolia L. has been related to variations in soil and air temperatures during four seasons (1997-2000). Its emergence appeared to be strongly dependant on soil temperature. Plants ... -
The Hardangervidda wild reindeer herd: a problematic management history
(Journal article; Peer reviewed, 2014)The unique and internationally important wild reindeer Rangifer tarandus herd on the Hardangervidda plateau of southern Norway has shown frequent and extreme fluctuations in harvest numbers for the past 60 years, despite ... -
Use of linear and areal habitat models to establish and distribute beaver Castor fiber harvest quotas in Norway
(Journal article; Peer reviewed, 2013)In Norway the Eurasian beaver Castor fiber harvest is quota-regulated. Once the annual quota for each municipality has been determined it is distributed to landowner-organized beaver management units. Municipal wildlife ... -
Variation in the structure of Matteuccia struthiopteris populations in Lithuania
(Journal article; Peer reviewed, 2006)Demographic data and associated phytosociological and environmental variables were sampled from 25 populations dominated by the fern M. struthiopteris studied in different parts of Lithuania. The main aim was to study the ... -
Will Trespassers Be Prosecuted or Assessed According to Their Merits? A Consilient Interpretation of Territoriality in a Group-Living Carnivore, the European Badger (Meles meles)
(Journal article; Peer reviewed, 2015-07-06)Socio-spatial interactions of Carnivores have traditionally been described using the vocabulary of territoriality and aggression, with scent marks interpreted as ‘scent fences’. Here, we investigate the role of olfactory ...
