Relationship between moose (Alces alces) home range size and crossing wildlife fences

Wildlife fences are today commonly used along highways to reduce the risk of vehicle collisions with wildlife. Since traffic and roads have expanded over the years, wildlife behaviour has become more interesting not only for the prevention of vehicle collisions but also to understand how human activities impact their natural habitats. Moose is one of those animals that have increased in interest in such studies. In this study, I tested if the probability to cross wildlife fences of moose would increase with increasing home range sizes, and also at what time of the year they cross. The study area is situated in Nordmaling municipality, located in Northern Sweden in the County of Västerbotten.

Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Bredspridning av grönmassa :

There are a great possibility to shorten the time between mowing and preservation by spreading of ley crops in connection to the conditioning. In this case the cellular respiration (the plants breeding that consume sugar until the crop is ensiled) should not continue as long and the forage will perhaps get a higher nutritional value. The capacity of the next machine could also be higher because the rake gives swaths with a lot of material. There is also a possibility that spreading of ley crops gives the material a more homogeneous content of dry matter and that gives a reduced growth of clostridium. This is particularly important when the method of harvest doesn?t include any mixing of the material like it does with a round baler or silagewagon.

Tjustempiren : fallstudier av Casimirsborg och Blekhem

This paper concerning the regional architectural term known as the Tjust Empire style analyses manor houses built in the Tjust area by the east coast of Småland in the period 1810-1860. The term Tjust Empire style was invented in 1937 by PhD. Manne Hofrén in his dissertation on architecture in Kalmar län in the period 1650-1850. The aim of the paper is firstly to determine whether there is a distinct difference between the regional Tjust Empire style in architecture and the common Swedish empire style or as its Swedish equivalent is known; the Karl Johan style. Secondly, the paper strives to analyse why and how the Empire style became so popular in the area during this period, focusing on architecture as a means to express social identity and status.

Vilka faktorer inverkar vid valet av transportföretag? : En fallstudie om företagskunders resonemang och prioriteringar vid köp av transporttjänster och val av transportföretag.

During the last couple of years the focus for many businesses have moved from just being price oriented to include such factors as quality, flexibility, service, delivery precision and environmentally friendliness. The shift in viewpoint arises from the increasingly competition on the market and the hard economic atmosphere. It has become more important to differentiate the company and its products to be able to increase market share. The purpose with this master?s thesis was to get a better understanding on how companies (customer to DHL) are reasoning and prioritizing when choosing Swedish carriers.

Yttrandefrihet i sociala medier

AbstractSweden has had a long tradition of freedom of the press and freedom of speech. Today the judicial area is regulated by the constitution of the press and the constitution of speech. The purpose of the two constitutions is to secure the right for every Swedish citizen to express their thoughts, opinions and feelings.The constitutions are designed to regulate the techniques with which the information is distributed and not to regulate the information in itself. This fact has caused a debate to arise on the subject whether the constitutions are still suitable to regulate the judicial area when the technical development causes the constitutions to get out of date and in need of constant updating. As a rule the usage of social media is not regulated by the constitution of speech the information distributed through these webpages can be included by the protection given by the constitution but very few of these webpages fulfill the criteria?s demanded by the constitution.The purpose of this essay is to ask the question whether the constitution of speech should be reformed to better regulate the technical development in the future.

Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

Naturvårdsavsättningar vid avverkning på Orsa Besparingsskog

Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions. The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.

Hållbarhetsredovisning - varför regleras det för svenska statliga företag?

Bakgrund och problem; Den svenska staten har tidigare beslutat att de statliga företagen skall ligga i framkant och vara föredömen i allt sitt arbete. I arbetet mot en hållbar utveckling har inte detta varit fallet och det beslutades därför, år 2007, att från och med 2008 skulle alla de statliga företagen publicera en hållbarhetsredovisning. Då tre av de statliga företagen, Vattenfall, SAS och Green Cargo fått utmärkelser av FAR SRS för sina hållbarhetsredovisningar undrar vi om inte de statliga företagen i viss mån redan är föredömen och ställer oss därför frågan ?Varför regleras hållbarhetsredovisning för de statligt ägda företagen?Syfte; Syftet med denna uppsats är att får förståelse för beslutet. Genom att granska de belönade företagen, Vattenfall, SAS och Green Cargo, hoppas vi att kunna få detta.

Från miljöbistånd till hållbart bistånd : - En historisk studie

AbstractWith this c-composition, I am trying to give a view over what has happened in the political area and the issues that concerns environmental aid. My analyze starts in the 60-ies when the environmental debate took of. It continues trough the 70-ies, 80-ies and ends in 1994 with the report that considers the UN-conference in Rio de Janeiro 1992, ?Sustainable Aid? and what the results of the more and more important issue ?sustainable development? has offered the Swedish government ant there work with environmental aid.The question issue is: At what time in history, did the Swedisch government start to addrsess environmental aid? How did the environmental aid come to be addressed and developed in the political area from the Brundtlandreport ?Our common future? from 1987 to the UN-conference in Rio de Janeiro 1992?The result is that the environment is getting more and more important in the political arena as the knowledge about the escalating crises with the environmental problems are being taken more seriously. The problems with the environment has to be considered together with the rest of the aid- and developing questions like economy and the struggle to reduce poverty in the world.
