Grodsamhällen längs vattendrag på Borneo : En identifiering av habitatkaraktärer viktiga för diversitet och abundans av grodor i tropisk regnskog

The stretch from the riparian zone of a major river, through the mouth and upstream in tributaries forms a range of differing habitats. The aim of this study was to investigate the effect of these different habitats on the riparian frog community in primary rain forest in Borneo; i.e. examine whether any gradients could be demonstrated in terms of species composition, diversity and density of frogs, as well as which environmental characteristics that seem to be of most importance in forming habitats of high conservational value. A major river, Segama, and three of its tributaries were investigated. The surveys were carried out at night by searching for frogs visually and acoustically along the streams, from the shore of the Segama river and 400 metres upstream in the tributaries.

A survey of cassava plants in the coastal region of Tanzania showing severe symptoms of cassava mosaic disease

Cassava (Manihot esculenta Crantz) is a root crop that plays an important role in many households in Africa. It is sometimes called ?Africa´s food insurance?. The advantages with the crop are that cassava is drought-resistant and it can grow in a semi-dry land. It is a perennial crop and does not require much labor.

BIODIVERSITETS P?VERKAN P? M?NGDEN ORGANISKT MATERIAL I ALSUMPSKOG: En fallstudie i fyra alsumpskogar p? svenska v?stkusten

Globally, coastal ecosystems like mangrove forests, sea grass meadows and salt marshes are well known for their ability to capture and store atmospheric carbon effectively. In Sweden, there is still limited knowledge about local coastal ecosystems with similar functions, with alder swamp forests being an interesting example. Therefore, this study aimed to increase knowledge of the factors that can contribute to the potential carbon sequestering ability of alder swamps. Vegetation data and sediment samples were collected from a total of 37 sampling plots across four alder swamps in Bohusl?n on the Swedish west coast.

Coco Beach from city dump to paradise : a design proposal for a public beach in Dar es Salaam, Tanzania

Sub Saharan Africa has during the last decade become the world?s fastest urbanizing region. This change is concentrated to a few metropolitan areas one of them being Dar es Salaam, the largest city of Tanzania. Since the 1960s Dar es Salaam has grown from being a relatively small coastal city of approximately 300 000 people to become a bustling urban centre of four million inhabitants. This development has had a major impact on the city structure, which in turn has affected people?s welfare and the surrounding environment. One such consequence is the detrimental loss of urban vegetation and open areas in the city.

?R KUSTN?RA ALK?RR I BOHUSL?N ETT ?BLUE CARBON? HABITAT?

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

En studie av sedimenttransport, död ved och kantzoner längs två vattendrag i Kilsbergen - från skog till slätt :

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.

Myrorna - subkulturens butikskedja : en studie i varumärkesutvecklande

AIM This report studies the Swedish vintage store company Myrorna from a branding perspective.METHOD The study has applied the qualitative method where four personal interviews have taken a fundamental ground. The four respondents are taken from different professionals and from different positions by the reason that the brand would be based on a fair assessment. The study is obtaining data that further was collected from the library of University of Gävle, the articles from Emerladinsight.com and remaining pictures- and text materials is taken from the organization Myrorna. The theoretical material have been adapted on the brand Myrorna and then been used to analyze the empirical part. From the general impression that portrays the brand the researcher leads the discussion.RESULT AND CONCLUSION The result shows that the brand Myrorna in some extent do not fulfill the image the brand in the media mediate, between the illusion and the reality there is an empty space according to the research.

Bottensedimentets betydelse för flodpärlmusslans föryngring ? en metodutveckling

The freshwater pearl mussel Margaritifera margaritifera is an endangered species. To survive, the young mussels demand a fairly coarse bottom material containing an appropriate quantity of organic substrate to survive without suffocating. In order to estimate if a bottom is suitable for juvenile mussels, samples of the sediment are needed. To obtain samples a sampling device called the Mulv collector has been developed within this project. Bottom samples were collected from 18 stations in 4 south Swedish streams, Vramsån, Kling-storpsbäcken, Brönnestadsån and Bräkneån.

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Ligger bäckarna rätt i kartan?

?Are the headwaters streams at the right position in the map? is a study that has been performed on behalf of Holmen Forest, region Örnsköldsvik. This study will be the basis for deciding if the Hydrology Layer Property map or Holmen Forest map will be used for planning nitrogen fertilization in forestry. The background to this study is that nitrogen fertilization near water will increase the risk of nitrogen leaching out into the water systems, which has a negative impact on the environment. The headstreams positions have been recorded in the field with a GPS and the data analyzed in the geographic information system ArcMap.

Hur påverkar bävern skogens värden?

The activities of beavers in forested landscapes affect both ecological and economical values. The creation of the dynamic wetland mosaic associated to beaver activities can even improve the quality of water and have been documented as an important landscape engineer affecting the environment for many species. The local office of Sveaskog in Skinnskatteberg is responsible for the management of large areas of the forests in the County of Västmanland. In this area one of several company?s goals are to create ten new wetlands in their own forests as a part of cooperation with the Swedish bird society and Swedish wetland association.

Från spel till e-sport : Vilka faktorer påverkar att ett spel utvecklas till en e-sport?

Uppsatsen kommer reflektera kring vad som gör ett spel till en e-sport med fokus på tre huvuddelar inom e-sport idag. Detta baseras på Klines, Peuters och Dyer-Withefords teori om Three Circuits of interactivity; Teknik, Marknadsföring och Kultur. Dessa tre delar utgör e-sport.Alla spel som finns på marknaden idag är tävlingsinriktade och går ut på att lösa problem, men alla spel är inte e-sporter och det finns även spel som försvunnit från scenen. Vi ville undersöka hur detta var möjligt. Vilka faktorer är det som gör att vissa spel bli e-sporter?Vi samlade information under DreamHack Vinter 2011 från flera källor inom e-sport.
