Behaviours of wild male and female Colobus angolensis palliatus during morning and afternoon in Diani Beach, Kenya

Colobus angolensis palliatus is a small old world monkey inhabiting southern coastal Kenya to southern Tanzania. The species activity budget is known to vary between Seasons and areas, probably due to differences in group sizes, diets, predatory presence and resource competition. The variations between male and female activity budgets are reckoned to be a result of pregnancy and lactation. The aim of this study was to investigate potential differences in behaviours between morning and afternoon periods and between males and females. The study was carried out in two forest fragments in Diani Beach on the south coast of Kenya.

Prevalence of selected infectious diseases in Samoan dogs

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya

Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording foraging behaviours include species, group size, environment, Seasons and age. The focus for this study was to determine which method is most appropriate for studying the foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.

Kan olika virussjukdomar blockera varandra? En studie baserad på övervakningsdata

Background: Infectious Diseases Institute points out that the potential of various viraldiseases possibly can block each other. It is said that the virus that causes common cold,Rhinovirus, may have saved many people from the flu. If this assumption proves true, itwould explain why some viral diseases in some countries have been slow to take off and pointto a new way to struggle influenza. Objective: The main purpose of this study, based onreported cases of RSV and influenza type A, type B and H1N1, investigate whether viraldiseases can block each other, i.e. difficult season of flu may delay and / or mitigate thespread of RSV in Sweden.

Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during Seasons, while the annual mean waterlevel will remain the same.

Radioktivt cesium (Cs-137) i vildsvin (Sus scrofa) från Tjernobyldrabbade områden i Sverige

In April 1986 an accident occurred at the nuclear power station in Chernobyl. Radionuclides were spread all over Europe including Sweden. Today there are still measurable concentrations of 137Cs in the different ecosystems in the contaminated parts of Sweden. The wild boar is the second most popular game in Sweden and today the Swedish population consumes more wild boar meat than ever. As the wild boar population increases the wild boars are moving further north towards the contaminated areas, which creates an interest to study the state of 137Cs in wild boars in these areas. Muscle samples from wild boars collected during 2010-2013 were analyzed based on 137Cs content.

Small scale pig production in Takeo province ina rural area of Cambodia

Cambodia, in Southeast Asia, has tropical monsoonal climate with distinct dry and rain Seasons. Many people are poor and live in rural areas. Farmers mainly culture rice, and raise pigs, cattle and poultry as well. During two months, a minor field study was performed in Cambodia. The main purpose was to evaluate the impact of contributions done by projects that started in 2005 and were managed by the local organization CelAgrid.

Den öländska älgstammens förvaltning : en granskning av förvaltningsplanerna och jaktens upplägg

To Swedes in general and, to hunters in particular, there is a great interest for moose (Alces alces), witch is Sweden?s largest deer species. In the province of Öland (Sweden?s second largest island) the local people show a great interest for the moose existence, both for consumptive (hunting) and non-consumptive use (tourism). This became apparent in 2002 when the moose hunters on Öland voluntary agreed to temporarily postpone the moose hunt on the island.

Den långa vägen till biblioteket : En studie om förskolors läsvanor och användning av biblioteket i ett mångkulturellt område

The purpose of this study has been to examine reading habits and the use of the library by pre­school teachers in a mainly multicultural community, and also explore to what extent activities in the local library are aimed at preschoolers.The study used a sociocultural approach based on Vygotsky?s theories of learning and development and Söderbergh?s theory of early childhood language development, and was carried out during the summer 2009. The methodology used was both quantitative and qualitative, with a combination of questionnaires and interviews. Questionnaires were sent out to each section of the municipal pre­schools within the catchments area of the local public library in a multicultural suburb of Uppsala. Three short interviews were carried out with staff at the local and main library branches, as well as library staff at the County Council.The results show that, although preschool teachers find reading important in their work, many teachers read spontaneously and/or sporadically.

En svala gör ingen sommar : en fenomografisk studie av elevers skilda uppfattningar av orsaker till att det finns årstider

Syftet med studien var att ta reda på de skilda uppfattningar av varför vi har årstider som kan finnas i årskurs sju. Detta gjordes för att få en bild av de olika föreställningar en lärare kan möta i sitt yrke och för att öka förståelsen och kunskapen om hur ett fenomen kan uppfattas på olika sätt av elever i en och samma klass.Eleverna ombads att, enskilt, skriftligt förklara varför vi har årstider. Studien är fenomenografisk och svaren kategoriserades i kvalitativt skilda kategorier genom att jämföra och finna likheter och skillnader mellan de insamlade elevutsagorna. Resultatet visade att eleverna hade olika uppfattning av varför vi har årstider och det är som lärare viktigt att vara medveten om att elever uppfattar samma undervisning på olika sätt. De uppfattningar som framkom var solens instrålning, jordaxelns lutning, jordens lägesförändring och avståndsvariation som skäl till varför vi har årstider.

Parasite detection in extensively hold Gotland ponies

Horses are herbivores that spend almost all day grazing. While grazing they are infected by different endoparasites through ingestion of infective eggs or larvae on pasture. The most significant equine endoparasites in Sweden are the equine roundworm Parascaris equorum, small (Cyathostominae) and large strongyles (Strongylus spp), the tapeworm Anoplocephala perfoliata and the pinworm Oxyuris equi. For many years have horses been dewormed on regularly basis, which has resulted in the development of resistance to many anthelmintic classes. Because of the problems with resistance it is since 2007 necessary to have a prescription on anthelmintics and faecal sampling is also recommended.

Thuja plicata - etableringsförsök av jättetuja med fyra olika provenienser

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing Seasons after plantation.

Design & Kreativitet ? och omvärldens orimliga krav

In a time where fast trends and shorter product lifecycles are dominating the clothing industryfashion companies must constantly deliver revolutionary products in order to survive. Theconsumers are more demanding than ever before and collections that used to be released twicea year are almost nothing but a memory lost. Some companies are now releasing theircollections continuously and have abandoned the Seasons completely. Media has put attentionon the speed that the fashion industry is moving in now and asks whether we can expect it toimplode?The purpose of the thesis is to establish how the creative process in a company operating onthe Swedish or the Danish clothing market is affected by external factors i.e.

Improvement in agricultural production in a rural area of Cambodia between 2004 and 2011 - with an emphasis on small scale cattle production

Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry Seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.
