Kommasköldlusen Lepidosaphes ulmi (Linnaeus) i svensk äppelodling : livscykel och naturliga fiender
Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en
pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
Mekaniserad plantering med Eco-Planter i södra Sverige :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting.
Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester.
The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive.
The biological output, e.g. planting result and survival rate, seems to be quite good.
Mognad hos unga flickor : normbrytande beteende, alkoholvanor och sexuellt beteende.
The aim of this study was to examine if biological early maturing girls and girls that percieved that boys treated them as older than they actually where drank more alcohol, were more delinquent, had more romantic relationships and sexual intercourse. Our data was collected from seven schools in Sweden. Significant relationships where found between early maturation and all four dependent variables. Significant relationships could also bee seen between how girls perceived that boys treated them and alcohol use, romantic relationships and sexual intercourse. For two of our dependent measures we found week interaction effects, for girls biological maturation and there perception of how boys treated them according to there age.
The role of FGFs in the elicitation of different cellular responses
Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

Inventory and evaluation of Nairobi Animal Orphanage : focusing on routines and feeding, black-backed jackal, lion and patas monkey
This BSc thesis is an introductory step to the collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS). It constitutes of an inventory of the Nairobi Animal Orphanage (AO), a facility that cares for injured and abandoned wildlife species in Kenya. Through the cooperation with Skansen, the KWS will improve their management of the AO. The aim of the inventory and BSc theses is to evaluate the management of black-backed jackal (Canis mesomelas), lion (Panthera leo) and patas monkey (Erythrocebus patas) regarding their biological needs. The general enclosures, routines and feeding at the AO are also evaluated since they have a great influence on the management of captive animals.
Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun
Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.
"Särskilt inte här i Sverige" : en studie av hur genus och religion framställs i läroböcker för gymnasieskolan
The aim of this paper is to examine how gender and religion is described and portrayed in relation to one another in Swedish textbooks. The research questions used in order to reach the aim of the study is what interpretation of gender and feminism is represented in the textbooks and is the gender perspective consistent regarding all religions described in the textbooks, or does it vary depending on which religion that is described?This study is based on four Swedish textbooks used when teaching religion in Swedish upper secondary school. The books chosen are published after the most recent curriculum for the upper secondary school, published in 2011. The curriculum gave new directions stating that questions of gender in relation to religion should be a part of the education.
Knista kyrkog?rd: ett rekonstruktionsf?rslag f?r den v?stra kyrkog?rden
This study focuses on a reconstruction proposal of a small part of a rural churchyard that has
lost a big part of its history, in form of its conformation and plant material. The chosen part of
the cemetery was established in 1938, and this proposal is an interpretation of the architect?s
original plan, the workers wishes and my own observations and experiences of the place. In this
proposal I have tried to balance the plants composition to create an environment that can benefit
the biological diversity, that fits the locations habitat and today?s maintenance.
Investment in project preventing deforestation of the Brazilian Amazonas
The aim of this thesis is to create an understanding of the incentives for forest companies to invest in reducing carbon dioxide emissions from deforestation and forest degradation, which is termed REDD. The Brazilian Amazonas was chosen as the base for the investment case. Brazil has the largest area of rainforest in the world, and also the biggest problem with deforestation. The Amazon region of Brazil comprises rainforest which is largely intact and unexploited. Accordingly, there is significant potential scope for prospective investments in a REDD-project, and so have a noteworthy impact in preventing deforestation.The research approach used the United Nation?s Clean Development Mechanism concept was used as a framework for ascertaining the investment costs in potential REDD-projects.
Bildandet av naturreservat : uppföljning och klimatanpassning
AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.
Samband mellan virulensgener och VTEC-infektioner : Riskklassificeringssystem för VTEC
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Introduktion av buskskikt i ungskogar
Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.
