The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown Bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by Bears rather than forests over 60 years that have not been commercially thinned in.

Brown bear (Ursus arctos) den site concealment in relation to human activity in Scandinavia

As a hibernating species, the brown bear spend most of the winter months in a den as astrategy to avoid unfavorable conditions. The denning period is a vulnerable time for Bears,making them unable to flee disturbances without losing valuable amounts of energy. BrownBears' wariness of humans and avoidance of anthropogenic disturbance often steer denningBears away from human infrastructure, and Bears thereby avoid possible disturbance and itsassociated energetic costs. This study was carried out to test the hypothesis that Bearsdenning closer to infrastructure select more covered den sites to compensate for the closedistance. Dens from 32 individuals were visited and analyzed in terms of sighting distance(a measurement for den horizontal cover) and habitat ruggedness, in relation to distances toinfrastructure.

Brunbjörnens (Ursus arctos) inverkan på den nya svenska älgförvaltningen

The European Brown bear (Ursus arctos) has gone from basically being extinct in Sweden to, 2008 being estimated to a total of 3298 individuals. When looking at the new Swedish moose management system it is important to have an ecosystem-based approach and therefore include all the parts that moose impacts on and from in the management, especially the brown bear. Primarily in the spring and early summer the brown bear is a significant predator on moose calfs which must be taken into account in moose management. When the bear recolonize areas that it has previously been eradicated from, it will once again come in contact with people who are not accustomed to the bear's role in the ecosystem. We studied three groups of moose management areas with different predation by Bears.

Patologiska förändringar och säsongsmässiga variationer i testiklar från svenska brunbjörnar (Ursus arctos) :

Functioning reproductive organs are essential for the survival of a species. The reproductive system is very sensitive to exposure of chemical substances of anthropogenic origin. Humans release great amounts of chemical substances to the environment by our means of life and these substances have been proved to have a negative effect on the reproductive ability of different vertebral classes. In the polar bear (Ursus maritimus) a declined reproductive ability as an effect of decreased testosterone levels and decreased testicular size has been connected to the presence of high levels of organohalogenic compounds like PCBs. Although the Swedish brown bear (Ursus arctos) is not as carnivorous as its close relative the polar bear it is still exposed to environmental.

Miljökemikaliers påverkan på isbjörnars (Ursus maritimus) reproduktion och hur dessa kemikalier når djuren

Environmental chemicals are transported to the Arctic through the air and oceans, once within the Arctic they spread through rivers, lakes and other watercourses. Polar Bears and sledge dogs in-gest high concentrations of environmental chemicals since many of the chemicals are fat-soluble and their diet mainly consists of marine mammals. The aim of this study is to describe how environmental chemicals spread in nature, how they reach the polar Bears, and finally how they affect the animals reproduction, with reproductive hormones and genitals in focus. The animals are exposed to a cocktail effect which complicates the assessment of the chemicals impact on the reproduction. Studies show that the genitals can decrease in size or become malformed, sexual maturation can be affected and the reproductive hormones can be disturbed.

Isbjörnars (Ursus maritimus) interaktioner och hägnutnyttjande på Orsa björnpark

SAMMANFATTNINGIsbjörnen är mycket populär hos djurparksbesökare och en viktig symbol för klimathotet, trots detta finns fortfarande många frågetecken kring hur vi ger isbjörnar i djurparker hög välfärd. I litteraturen har vi länge talat om isbjörnar som solitära djur men trots detta låter vi dem ofta dela hägn med andra isbjörnar på djurparker. Det har observerats positiva effekter av grupphållning av isbjörnar, bland annat sänkt förekomst av stereotypa beteenden, men vi måste vidare utreda vilken påverkan det har på deras välfärd. Ytterligare problem för isbjörnar på djurparker är stereotypt vankande som har observerats hos flertalet karnivorer som i det vilda rör sig över stora områden eller hemytor. Syftet med denna studie var att titta på hur isbjörnarna på Orsa björnpark utnyttjar sitt hägn, vilka beteenden som kan observeras samt hur stor del av observationerna de spenderar tillsammans.

Vilka stereotypier finns hos brunbjörn (Ursus arctos), lodjur (Lynx lynx) och varg (Canis lupus) i djurpark och vilka berikningar finns? : förslag och rekommendationer om berikningar utifrån djurens beteendeekologi

The purpose of this work was that with the help of a literature review have a single document with information on how the various species: brown bear (Ursus arctos), lynx (Lynx lynx) and the wolf (Canis lupus) living in the wild. The aim was also to show which stereotypic behaviours these different species have in zoos and the enrichments that is already being used and to make suggestions and recommendations on enrichment based on animal behaviour ecology. In zoos, some species thrive well while others have propositions to propagating problems, poor health and stereotypic behaviors. The brown bear, lynx and wolf, live both in the wild and in zoos in Sweden. As these animals have different ways of living in the wild, it is important to accommodate to each species, the way they are kept in zoos in accordance with their behavioural ecology.Brown Bears are omnivorous and solitary living species with large energy needs so that they spend most of their day to actively feeding but also rest.

Matematikkunskap och självkänsla, ett samband?

Med förskoleklassen i centrum är syftet att få utökade kunskaper kring matematiksvårigheter samt vilken betydelse självkänslan kan ha för matematiklärande. Studien är baserad på kvalitativa intervjuer byggt på Diamant samt en observation med materialet The Bears kopplat till testet. Tidigare studier tillsammans med vår empiriska undersökning visar att matematikkunskap och självkänsla har ett samband och att de båda kan påverkas av undervisningens upplägg. I studien framkommer det att diagnoser och observationer samt lärarens roll är betydelsefulla pedagogiska redskap, både för självkänsla och matematikkunskaper..

Att skriva, skriva om och skriva om sig själv : En komparativ undersökning av Inger Edelfeldts och Bengt Martins omarbetade berättelser om homosexualitet

Inger Edelfeldt (1956) and Bengt Martin (1933-2010) are two Swedish writers of different generations. Both of them did, between the years 1968 to 1983, write about adolescent men coming to terms with their homosexuality. Edelfeldt wrote two versions of the same story, with slight but significant differences, the main being different implied readers (adult versus adolescent). Bengt Martin wrote about three young homosexual characters: Joakim, Bengt and Bengt. The story about Joakim is presented as fiction but Bears many resemblances with Martin?s autobiography.

Name your price - a study of a pricing strategy

An industry in distress was the breeding ground for a noted pricing strategy, labeled name-your-price. The industry was the music industry and the pricing strategy Bears reminiscence of how medieval buskers earned their living during the dark ages; by letting the customers decide how much the good was worth, embodied by a thrown coin into a hat or similar collector. Translated into the contemporary corporate environment of today, where technical innovations provides access to the intellectual property for free, a few mighty economic actors have once again turned to the strategy were it all started; letting the customer set the price. The hat has been replaced by a box for your credit card number and the live music by a MP3 file, but the similarity is striking. The business model have been applied in other industries as well with various levels of success, thus the purpose of this thesis is to set up a framework for where the name-your-price strategy is applicable.

Livskunskap : En inre kompass i skolan

Through qualitative interviews with five teachers from three schools, two public schools within the same school management and a Waldorf school, the purpose of this study is to find out teachers' views on the phenomenon of life skills in the lower classes in school. What is the subject, how do teachers work with life skills, and should it be seen as a separate subject or integrated in all school subjects?The results show that the definition of life skills is a term with many interpretations. Two concepts that can be seen as the common denominators in the educators' views on the subject, however is, social and emotional skills. This is something that educators believe develop self-awareness and empathy in children and sees that as important as learning other subjects.

Leanbana till toppen - En studie om Lean-implementering i skidsystem

The ski resort is a business unlike any other. While providing the customer with a service, it produces the service in a manner that in many respects resemble the traditional producing company. Therefore, since the challenges facing the ski resort are a mixture of what can be found in these different environments, this study aims to investigate the applicability of Lean principles in this context. With a qualitative approach based on direct observation, combined with survey data from 2819 respondents, we evaluate the expected effects on customer value of ten commonly defined Lean principles. The study finds that although Lean theory can help disseminate customers throughout the resort and provide greater transparency, the nature of the operations calls for caution.
