Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication

Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a Domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.

A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being Domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants. In this thesis I investigated the effect of Domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.

Allanblackia stuhlmannii ? a tree under current domestication: what are the soil requirements?

Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply. Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.

Intryck som ger avtryck i en krympande värld : En kvantitativ undersökning om utrikesnyheternas fokus de senaste 30 åren

We have inquired into how the amount of foreign news has changed over the last 30 years in two major Swedish newspapers, which subjects and regions has dominated the content of the foreign news and what subjects dominate the reporting from certain regions. This was done with a quantitative analysis of subjects and regions written about in 1100 news texts during a week in each year of 1978, 1988, 1998 and 2008. To further broaden our study, we also charted with the analysis how the newspapers domesticate foreign news and how they use international news agencies. As a basis for our discussion we use Van Ginnekens theories of world news centres, Westerståhl & Johanssons and Galtung & Ruges theories of foreign news selection as well as the theories of Hjarvard and Biltereyst about the Domestication of foreign news due to commercial pressures and objectives on the newspapers. Our result of the amount of foreign news in the two newspapers is also compared to several similar empirical studies by different researchers.

IKEA är ett svenskt heminredningsföretag som verkat i ca 50 år och dess varuhus återfinns i många länder runt om i världen. IKEAs koncept och marknadsföring har översatts till många olika språk och de fortsätter sin expansion in i fler länder. IKEA är känt för sin definierade företagskultur och sitt starka företagskoncept. Dess framgång står bland annat att finna i dessa. IKEA anses vara byggt på svenska och i synnerhet småländska kulturella grunder och värderingar som kanske inte alltid kan tas för givet i andra kulturer.

Hästar som utför vävning

The horse is an animal that often becomes humanized. Despite Domestication, the horse still has a need to interact with other horses, be able to move for the most of the day, and being able to graze. If these needs cannot be fulfilled, the horse can be negatively affected and develop abnormal behaviours. An example of abnormal behaviours is weaving; the horse performs a swinging motion in the front area of the body during a long time. This literature review aims to investigate how different stabling forms (box/stall) affect the incidence of weaving, and also how this behaviour can be prevented or limited.

Svin och deras betar : en studie av svinbetar från mellanneolitikum

This thesis deals with the importance of boar tusks to the people at the Middle Neolithic settlement of Ajvide, Eksta parish on Gotland. The thesis discusses various issues concerning the Ajvide swine and their tusks, such as the question of Domestication and the various functions ascribed to tusks. In order to cast light upon these questions the result of a study of all the tusks found on Ajvide thus far as well as their respective grave context is presented. The study also includes an osteological analysis of the tusks. Furthermore, ethnoarchaeological comparisons are made with Papua New Guinea and Vanuatu; contemporary societies presumed to share common traits with Middle Neolithic societies on Gotland and where swine and their tusks likewise assume a prominent position..

?I am not well, and need a change? : Charlotte Brontës Shirley i ny översättning

Den här masteruppsatsen består av fyra delar: en nyöversättning från engelska till svenska av ett utdrag ur Charlotte Brontës roman Shirley (1849), en översättningskommentar som går igenom ett antal problemområden, en språklig undersökning samt ett avsnitt om nyöversättning.Den språkliga undersökningen utgörs av en jämförelse mellan användningen av pronominella adverb i uppsatsens översättning av Shirley och i den äldre svenska översättningen från 1854.

Från vilda till domesticerade djur - kan man gå ett steg längre?

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Separationsångest hos hundar : etiologi och möjliga behandlingsprotokoll

Behavioral problems are one of the leading reasons for re-homing and euthanasia in dogs. It is estimated that between 40 ? 87 % of dogs suffer from some sort of behavioural problem, making it an important animal welfare issue. Separation anxiety is one of the most common behavior problems encountered in dogs after problems related to aggression. This thesis is aimed at examining the etiology behind separation anxiety related behavior in dogs based on existing literature as well as comparing and evaluating the efficiency on suggested treatment protocols.

Höns återhämtning efter stress samt domesticeringens effekter : En biologisk studie med ett lärarperspektiv

Den biologiska studien har visat att värphöns genom domesticeringen förändrat och anpassat sina beteenden till att leva med människor. De har utvecklat en minskad rädsla för människor och en ökad stresstålighet. I denna studie har höns återhämtning efter en stressupplevelse studerats. För att se hur domesticeringen har påverkat återhämtningen jämfördes beteenden mellan raserna White Leghorn och red junglefowl. Frågeställningarna som användes för att undersöka detta var: Hur lång tid tar det innan höns återhämtar sina naturliga beteenden, ej stressrelaterade, efter en stressupplevelse? Finns det några skillnader i återhämtningen beroende av kön eller mellan raserna White Leghorn och red junglefowl? Resultatet visade inte på en specifik tid för återhämtning men på att en tydlig återhämtning förekom.

Människans inverkan på hundar ? och hur det kan påverka arbetet inom djursjukvården

The aim of this study was to describe how body language of humans affects the domestic dog (Canis familiaris) and how it can be implanted in the stressed situation that occur at an animal hospital. The subject is brought to notice because the author has experienced that dogs can get more stressed when a stressed and nervous owner is attending. Humans affect each other through posture, facial expression, voice and movement, and are often driven by their emotions, which can differentiate the verbal communication from the non-verbal communication. This occurs both consciously and unconsciously. Every human uses body language but not everyone knows how it is used or how to understand it.

Skyddsrum och kärnvapen : En diskursanalys av 1950- och 1960-talets försvars- och civilförsvarsdebatt i svensk press

Shelters and Nuclear weaponsA discourse analysis of the Swedish defense and civil defense debate during the Cold warSweden during the Cold War set into motion one of the world?slargest civil defense policies at the time, second only to neutral Switzerland. The governments expenditure was far greater per capita than both that of USA and Soviet Union and included massive evacuation plans for Stockholm and other large cities in Sweden, with the hopeful expectation to bring down the amount of people in each of them to 15000 in case of a foreign hostile nuclear attack. The policies included construction of shelters with room for 2,5 million of about 7 million citizens in total at the time along with gasmasks for the whole population. Not only this, Sweden was considered one of the biggest military powers of that time in relation to its size and population.
