Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Variation in protein precipitation and phenolic content within and among species across an elevational gradient in subarctic Sweden

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Utfodring av föl före och efter avvänjning :

Swedish horse breeders have generally very few mares producing a few foals a year and the breeders have relatively few traditions, little knowledge and experience to breed foals successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply. This paper reviews some publications in the area of feeding the suckling and weaning foal. Most authors stress that it?s important to start feeding the foal early in life.

Increased growth in Norway spruce (Picea abies (L.) Karst.) through small annual additions of nitrogen (N) fertilizer

Hur arbetar lärare med nyanlända elevers andraspråksinlärning i förberedelseklasser? : En kvalitativ studie om undervisningsmetoder och materiel för nyanlända elever i förberedelseklasser

We are living in a multicultural society where people from other countries and other cultures are coming to Sweden, including children. Regardless of reasons why these students have come to Sweden, it is common that they are newly arrived and have to learn a second language, in this case Swedish. This will be a challenge, opportunities and difficulties for the student, students? families and for the school and their staff.The purpose of this essay has been to illumine the teaching methods, models and what materials are used by teachers today to contribute to the best possible second language learning for newly arrived students. In this essay the focus has been on one theory and several model-based approaches.

Åre kommun och klimatförändringar : En studie kring hotet mot Åre kommuns vinterturism och dess anpassning till framtida klimatförändringar

Today?s climate research shows that the climate may increase its temperature. One sector that is being threatened by global warming is the winter tourism of the Swedish municipality A?re. Tourism is an important economical source of income in A?re and is now threatened by a shortened winter season.

Död ved i ett referensvattendrag

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.

Organisationsplan för Skanska Direkt Värmland

AbstractSkanska Sweden has decided to split the organization that earlier handled both large and small projects into two different subsidiaries. A consequence of this is that all construction service handling will from now on be enforced under the name Skanska Direkt AB. The management of Skanska sees this as an opportunity to develop the organization and in the long term achieve higher earnings.   The task which Skanska in connection with the reorganization wanted to be investigated was a proposal on how the organization of work with the insurance work in the future should look like.The organization that is handled is from production manager to professional workers and includes damage handling that has been obtained from insurance companies in the southern and northern parts of Värmland. The purpose with this work is to present a different kind of view to the problem with developing this branch of the company. The main target was to work out a proposal of an organizational plan for the damage handling in Skanska Direkt AB that is possible to apply, less sensitive for dismissals, results in higher earnings, obtains higher customer satisfaction and also a staff stab that develops their skills at their own.The report and work progressed as following:Opening theory study of strategies to obtain the objectives set.Restructuring of existing organization with theories as support.Interviews with the actors involved to verify feasibility of the developed organization plan  Organization chart, the result of work means that some workers at each location shall be responsible for a small group of workers and work independently. They shall manage the process of invoicing and calculate costs at the same time as they work out on the workplace.

Problemidentifiering och utveckling av plocklagerverksamhet

Ellos was founded in 1947 by Olle Blomqvist and quickly grew into one of the leading mailorder businesses in Sweden. Ellos Group is in the current situation Scandinavia?s largest ecommercecompany and since 1997 owned by the French holding company Keering. Thismeant that Ellos became a part of Redcats Nordic along with brands such as La Redoute,Verbaudet , Daxon and others.2010 started a project with the aim to develop a logistic model for these products. The resultwas the department Redmap on Ellos that would serve as both a hub and distribution channelfor Northern Europe.

Utbyte av massaved och biobränsle i några typbestånd av Contorta :

The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog. Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.

Påverkar jordbruk flödet av akvatiska insekter till land? : Effekter av jordbruk på akvatiskt tillflöde till land vid norrländska bäckar

Streams and riparian zone are closely linked by reciprocal flows of energy and nutrients. A large part of the transportation from water to land is in form of emerged aquatic insects. Conversion of land from forest to agriculture can greatly affect aquatic ecosystems, and due to the close link, also affect the adjacent terrestral zone. Investigating how the presence of agriculture in the surrounding area affects amounts of emergent aquatic insects gives an indication on how agriculture, in turn, may affect the terrestral enviroment. The study was preformed alongside ten streams in northern Sweden; five in landscape transformed by agriculture and five in undisturbed forest areas.

Habitat use and ranging behaviour of GPS tracked juvenile golden eagles (Aquila chrysaetos)

Throughout its wide distribution in the northern hemisphere, the golden eagle occurs in a diverse range of environments, e.g., mountainous, forest and open areas. The literature on juvenile golden eagles is limited, and this study provides further knowledge on habitat use and ranging behaviour during the post-fledging period in boreal Sweden. A total of 14 golden eagle juveniles were tagged with GPS transmitters during 2010 and 2011, and nine could be followed during the entire post-fledging period from fledging until migration. The juveniles fledged at the end of July and beginning of August and initiated migration during October and beginning of November. The length of the post-fledging period, until migration started, ranged from 49 to 97 days. During this period, the juveniles? distance from their natal nest and their GPS height increased with time as their flying abilities developed.

Värdering, Grafik och Logik : En kvantitativ studie av svensk nyhetsgrafik

News graphics as a part of journalism is something that?s constantly developing along with the news. That?s what we believed when we started this paper including its study. And we still believe the same, now that we?re done.News graphics itself is fairly common in Swedish newspapers, it can be seen every day in almost any major newspaper and is perfect for describing an event like the pollution of the sea over many years or just simply point out on a map where a city is located.This is one of the reasons to why we wrote this; another reason is that there?s almost nothing else written on the subject in northern Europe.

Strategic forest planning using AHP and TOPSIS in participatory environments : a case study conducted in Vilhelmina, Sweden

When a decision is to be made on what long term strategic forest management plan to use, consideration must often be taken to multiple objectives. Such decisions are very complex and a promising approach to handle them is by Multiple Criteria Decision Analyses (MCDA). The study is based on the problem that the MCDA that have been implemented into forest management planning have only had capacity to compare and evaluate a limited number of management plans; which means that there is a risk the most suitable plan is missed. The aim with this study was to test the applicability of combining the MCDA tools: the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and the Analytic Hierarchy Process (AHP) for including consideration to multi-objectives into strategic forest management planning. The study was based on the process of creating and selecting a management plan, using Heureka PlanWise, suitable for all the major objectives found in the forest holdings of a municipality in northern Sweden.

Fjällfåglar : En jämförande studie från dal till topp i ett nordligt och sydligt svenskt fjäll

Title: Mountain birds ? a comparative study from valley to mountaintop in a northern and southern Swedish fjeld  Author: Kristian Zackrisson Abstract Main aim in this study was to increase the knowledge about birds in the Swedish mountain area. Three questions were asked: 1) Which bird species can be found during the breeding season along a low mountain slope from a forested valley to a mountaintop with bare mountain environment? 2) Do the number of species and individuals differ in different elevation zones? 3) Is the composition of bird species along a low mountain slope the same in the Kebnekaise mountains inLaplandand the Grövelsjön mountains in Dalarna? Bird census in two study sites located in the Kebnekaise mountains and the Grövelsjön mountains and subsequent analysis of the results from the bird census was the main parts in this study. Totally 20 bird species were found along a low mountain slope in the Kebnekaise mountains.
