The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation

The Loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours. In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.

Hotade arter i tallmiljöer på Sveaskogs mark i Västerbotten och Norrbotten : skötselförslag och analys av potentiell habitatutbredning

Skogens biologiska mångfald hotas främst genom den påverkan som människan har på naturen. Skogsbruk och bekämpning av skogsbränder leder bland annat till att landskap och habitat fragmenteras samt att mängden död ved minskar i skogen. Naturvårdsverket och länsstyrelser arbetar inom ramen för de nationella miljömålen med åtgärdsprogram för hotade arter. Detta som ett led i arbetet med bevarandet av den biologiska mångfalden. Många hotade arter har en dålig spridningsförmåga, därför krävs planering utifrån ett landskapsperspektiv där stora sammanhängande områden sätts av och restaureras.

Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie

Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.

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.


Flickors bruk av och attityd till illegala viktminskningspreparat. : En enkätundersökning riktad till flickor i årskurs tre på gymnasiet.

Newspaper articles and media have shown that the use of illegal weight loss compounds, such as ephedrine and Melanotan, is becoming more common among adolescent girls, who are at risk of becoming a new group of addicts. These girls are rarely aware of the risks that the use of these compounds entails and the consequences that could adversely affect their bodies, mentally and physically. The aim of this paper was to investigate the use of and attitudes towards illegal weight loss compounds amongst girls in year three, at Swedish upper secondary schools. In order to do that, a questionnaire was sent out to 120 girls in five different high schools, with varying college preparatory and vocational program directions. My research shows that the use of illegal weight loss compounds, particularly ephedrine, was found among girls in year three, at upper secondary schools. Seven percent of the girls claimed they use, primarily, ephedrine. This result exceeds earlier studies findings on boys' use of anabolic androgenic steroids (AAS).

Reparationsstrategier i uppgiftsorienterad interaktion mellan personer med hörselnedsättning och deras anhöriga

The present study deals with task-oriented conversations between a person with hearing loss and a relative or friend. The purpose was to investigate how the participants in the task-oriented context co-construct understanding, and to focus on different kind of repair strategies that the participants may use to make the hearing loss relevant in the conversation. The method used was Conversation Analysis (CA). The material consisted of eight videotaped task-oriented conversations between a person with hearing loss and their significant other. Altogether eight persons participated in the study ? four of them had a hearing loss and the other four had normal hearing.

Earnings Management & Loan Loss Provisions?

Ämnesord: Earnings management, loan loss provisions, konstaterad kreditförlust, Basel II,kapitaltäckning, bank, noterade, onoteradeBakgrund och problem: Justering av resultatposten loan loss provisions är ett vanligtförekommande verktyg för earnings management inom banksektorn. För att öka stabiliteten inombankväsendet så infördes kapitaltäckningsregleringarna Basel I år 1988 och år 2007 uppföljarenBasel II. Den senare antog en mer principbaserad roll och innebar en ökad kontroll och tillsyn avbanker. Det är därför intressant att studera huruvida Basel II har haft någon effekt på redovisningenskvalitet och därmed lett till reducerad earnings management.Syfte: Studiens övergripande syfte är att undersöka effekterna av genomförandet avkapitalregleringen Basel II på resultatposten loan loss provisions och earnings management inomdet svenska bankväsendet. Vidare studeras noterade samt onoterade banker för att utröna om detföreligger en skillnad i dess sätt att hantera loan loss provisions.Metod: För att uppnå syftet med studien så har en kvantitativ metod tillämpats.

The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?

The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.

Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods

Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).

The influence of active bomas on habitat choice of the common warthog (Phacochoerus africanus)

The common warthog (Phachocoerus africanus) is a relatively long-legged pig with noticeable curved tusks, a short neck and three pairs of facial warts. It has four recognized subspecies. The common warthog is a non-migratory ungulate living on the African savannah. It is a hindgut fermenter and predominantly dependent on high-quality foods. It prefers open areas for grazing but use bushes for cover.

Hörapparatnyttan hos dem som ordinerats hörapparat med öppen anpassning ? En utvärdering

An open fitting is suitable for persons with sloping hearing loss and relatively good low fre-quency hearing. Sensory neural hearing losses often have this type of configuration. A large ventilation canal gives a greater feeling of comfort and less occlusion. The purpose of this study was to look at the hearing aid benefit of open fitted hearing aids. Self report question-naires were sent out to 102 patients who were given ReSound AIR during the year of 2006 in Uddevalla.
