Betula : arter och sorter
As birch is one of the most common trees in Sweden, and probably one of the easiest for
someone who lives here to identify, it is interesting to note that most people do not know
how variable the genus is and how widely it is distributed across the northern hemisphere.
One can find birch growing at both high and low elevations, demanding different soil
conditions and preferring varying amounts of sunlight. Many people may also be surprised to
hear that the colour of the bark can vary from bight white to almost black, and different
shades of pink, orange and red can also be displayed. This, together with the astonishing
beauty of the genus, the important role as a pioneer in many ecological systems and the
difficulty in sorting out the taxonomy of the genus, constitutes the background of this thesis. The thesis is written at the Department of Landscape Development in Alnarp, Sweden with Kenneth Lorentzon, researcher at the Swedish University of Agriculture as a supervisor. The aim of this thesis is to highlight which species and cultivars within the genus Betula could be appropriate for horticultural use in Sweden.
Det bästa av två världar: en analys av bibliotekskultur vid Malmö högskola
The study of culture is specifically relevant to libraries confronting changes. A variety of conditions makes it beneficial for libraries to understand the strengths as well as the weaknesses of the underlying culture. Such an understanding can help libraries in adjusting to changes easier, without losing the cultural values that they hold important to their identity and strategic strengths.Taking this as a starting point the purpose of this essay is to examine and describe what aspects in prevailing library cultures are important to pay attention to when meeting changes. To accomplish this we will explore the concept of library culture, its substance, meaning and expression.Culture is reflected in the artifacts, values and underlying assumptions of formal and informal groups. Culture can be found at various levels.
Evaluation of an ectomycorrhizal macrofungi as an indicator species of high conservation value pine-heath forests in northern Sweden
Since the 1950s, the development of modern rotation forestry in boreal Fennoscandia has resulted in a severe reduction of older forests, and a high degree of fragmentation among the small patches that remains of old forest. In Sweden, when performing conservation value assessments in order to identify and preserve the remaining forest habitats, the government authorities use to a significant extent a set of indicator species that indicate habitats of high biological conservation value. One species considered to indicate high conservation values in pine-heath forests is the red-listed ectomycorrhizal (EM) macrofungi Sarcodon scabrosus (Fr.) P. Karst. In the present study, the validity of using S.
Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)
The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.
Skånes gröna guld : anläggning, odling & mossarter i mossträdgården
This is a 15 hp (10 p) thesis in biology at the programme for Horticulture Management at the Swedish University of Agricultural Sciences, Alnarp. In this literature study we have processed, reviewed and arranged facts and research, to make it more available for those who want to know more about establishment or cultivation of mosses. Our client is Fredriksdal?s Museums and Gardens in Helsingborg who are planning to establish a moss garden. The information is meant to be used by Fredriksdal and other similar facilities.
Ett grönt möte mellan eklandskapet och en ny stadsdel i Linköping :
The purpose of this essay is to analyze and show possibilities how a city can grow into the scenery of a oak dominated landscape and how this encounter can add values to the city.
The city in focus is Linköping, a city that is approaching one of Sweden?s largest oak dominated cultural landscapes. To this landscape high ecological and cultural values are connected. The recreational values are also of importance especially because of its urban location also because the city is mainly surrounded by flat agricultural land.
Stadsodling : möjligheter och begränsningar
Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.
Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management
Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.
Skötsel av älgskadade bestånd :
Sweden has today the highest moose (Alces alces) population in the world. The population has been very high since the late seventies and in the beginning of the eighties there was a big ?moose explosion?. The main food source for moose during the winter is young pine (Pinus sylvestris) and birch (Betula spp.). The high moose population has therefore lead to high damage on pine forests over big areas.
Turkiet vänder blickarna mot öster : -en fallstudie av Turkiets utrikespolitiska förändring gentemot Mellanöstern
AbstractTurkey has emerged as a major actor in the Middle East over the last decade, since the ruling party AKP came to power in 2002. Turkey is now playing a mediation role in regional conflicts and has been speaking out loudly on sensitive issues such as the Iranian nuclear program and the Palestinian- Israeli conflict. Furthermore, Turkey has established close ties with the Arab world which has suffered the relationship with its long-time ally Israel. This new presence in Middle East has been criticized by Turkey's allies in west. Critics argue that the country is about to abandon its former western relationship and strengthen their ties with the Arab world instead.This thesis has two main purposes.
Älgbete och skogsskador på beståndsnivå :
The modern silvicultural practices of today, with cutting by compartments, have led to a large benefit for the moose population through the cleared areas which produces large amount of fodder. This new landscape can produce and feed a large moose population. But it will cause a conflict effect towards the landowners; the conflict consists of browsing mainly in the young pine forest. The result from browsing and damage will be sparse stands with reduced growth and technical damage like leader shoot browsing, stem breaking and damage of the bark. Technical damage can kill the tree or damage it so hard that it would not work as future saw timber.
Strategier vid generationsskifte : ekonomiska implikationer för olika intressenter
A large number of farms within the agricultural sector will shortly be facing a point of time where the farm will be transferred to the next generation. The grantor can choose between totally 8 different strategies to transfer the farm, of which purchase, gift and a mixed form of these are the most common. During 2007 almost 10 000 transfers of agricultural estates occurred in Sweden and the expectation for the coming years is that about 15 000 estates will be transferred each year. By the time a transfer is about to materialize there are usually several stakeholders that in one way or another is trying to influence the outcome of the transfer. The choice of transfer method affects the conditions and possibilities for compensating the siblings.

Managementperspektiv på grisproduktion i Lojsta :
At the farm Fride, in Lojsta at the Southern part of Gotland, my family runs a pig production with 80 part-integrated sows in a ?Familybox-system?. The main parts of the facilities are from the early 90´s and have done their job. The production results have the last years decreased because of new infections so we have to do something before shifting ownership!
This degree thesis is meant to answer the question about which the optimal extension would
be today. By studying literature, use my own experience and make lots of calculations, I try to find out different opportunities.
