Wetland development in the context of ecotourism : a conceptual design proposal for a wetland site in Lake Victoria, Kenya
The travelling sector is expanding worldwide, which puts all destinations under pressure to have a functioning
social system and good resources to manage the problems and take advantage of the opportunities that the
tourism sector can offer a community. The area around Kisumu in Kenya, like much of Africa, tourism can
simultaneously ensure a stable financial future while it removes, as a result of a growing population, more and
more of the scenery that many tourists want to experience. Responsible travel to natural areas that promotes
conservation of the environment and improves the welfare of local people is what defines ecotourism. A
concept that implies a closed cycle, where visitor?s needs are met in balance with what can be given back,
without risking creating imbalances in society.
Along the coast of Lake Victoria, valuable papyrus wetlands provide Kisumu vital ecosystem services
such as water purification, climate adaptation while it also serves as a reservoir for biodiversity.
Markägare i Stockholms län och deras inställning till biodiversitet och skydd av mark :
This report investigates what attitude private forest owners in the County of Stockholm,
Sweden have towards biodiversity landconservation. Private landowners were asked to
answer a questionnaire containing questions about there property and there attitude towards biodiversity. The results show that private landowners attitude towards biodiversity is affected by, amongst other things, the size of their property; a larger property have a more negative owner than a smaller property. A landowner that lives on his property has a more negative attitude towards biodiversity than a landowner that?s not living on his property.
Biologiundervisning utomhus : En studie av utomhusundervisningen inom biologiämnet i grundskolans senare år.
Syftet med detta arbete är att studera utomhusundervisning inom biologiämnet i grundskolans senare år. Arbetet syftar även till att fastställa Ekobussens roll i utomhusundervisningen. Frågeställningarna lyder som följande:?Vilken inställning har lärare till utomhusundervisning inom biologi??Vad finns det för fördelar och nackdelar med utomhusundervisning??Vad får elever ut av utomhusundervisning??Hur använder sig lärare av Ekobussen och vilken inställning har de till den?För att få svar på dessa frågor genomfördes en enkätundersökning med lärare och elever samt djupintervjuer av tre lärare.Resultatet i undersökningen visar att både lärare och elever anser att utomhusundervisning inom biologiämnet inte bedrivs i tillräcklig utsträckning. Orsaker till detta är bland annat osäkerhet hos lärare, brist på bra exkursionsplatser i närområdet samt att det är schematekniskt svårt att få tid att komma ut.Undersökningen visar att de stora fördelarna med utomhusundervisning inom biologi är att eleverna anser sig koppla teoretisk och praktisk kunskap samman samt att många sinnen stimuleras vilket underlättar inlärningen..
En studie om hanteringen av Rasbiologiska institutets samling och känsligt material vid Uppsala universitet
The Swedish institute of racial biology was the first of its kind in the world. The purpose of their activity was to gather information about the different kind of racial characters of the Swedish population. They did this by traveling around the country gathering pictures and statistic information. In 1958 it was decided that the institute was going to get integrated with the University of Uppsala and change its research focus to a more medical genetic. Most of the research material also got integrated into the university?s library.The purpose of this paper is to find out how the institutes collection has been handled through the ages and if there have been any controversy or debate about it.
Stenebergs sockerbruk: en fallstudie av en timmerstomme fr?n 1739
Stenebergs sockerbruk is a large log-timber construction, purpose built as a sugar refinery in
1739 and is one of Sweden's oldest industrial buildings constructed entirely out of wood.
Despite receiving the status of a listed building (in Swedish: Byggnadsminne) in 1977, there
exists today a surprisingly low amount of documentation of the building itself. In order to
enhance the existing and lacking building documentation, this case study aims to shed light
on the building's log-timber built frame, focusing on how it was constructed, how the long
lengths of its walls were handled and what type of joinery and tools were used.
A thorough investigation of the building is conducted on site, followed by gathering of
information which is then presented through text and illustrations. The findings indicate the
orientation of timbers, location of joints and scarfs as well as tool marks which together
contribute to the forming of a basis of understanding of the building's construction..
Jätteuttrar och deras beteende när de tilldelas musslor i hägn
The giant otter (Pteronura brasiliensis) is listed as an endangered species and scientific litterature concerning its biology and behaviour is scarce. The current study observed a group of three giant otters in a Swedish zoo. First the otters normal behaviour was recorded. Then the aim of the study was to see if the otters behaviour changed when given blue mussels (Mytilus edulis). Furthermore the aim was to see if the otters displayed any tool-using behaviour when given mussels.
Beslag eller buckla? : En studie av platta järnfragment från hallhuset i Birkas Garnison
This paper deals with flat iron fragments from the Viking Age hall situated in Birkas Garrison, Adelsö parish in Uppland. The aim of the study was to identify which objects these flat fragments were originally derived from. The aim was also to discuss the function of these objects and their presence in the hall. This would hopefully increase the knowledge about the hall and the warriors who lived and worked there. In some cases the fragments form and placement in the hall has not provided enough information to classify the object from which they derived.
Biovetare, bibliotek och bioinformatiska resurser
Bioinformatics is an interdisciplinary scientific subject which connects biology, biomedicine and information science. Bioinformatics generates new biological knowledge by using computer methods and biological databases and can thereby play an important role for the understanding of diseases and be used for development of new medicines. The appearance of bioinformatics has thereby had a big impact on biomedical research.In this study, I have examined bioscientists' use of bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and their needs of support concerning these resources. I have also examined which support the scientific libraries offer their users concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools and have compared it with the needs the libraries think that the users have and the needs the users state that they have.The results from the study show that there is a wish for library support concerning bibliographical databases, bioinformatic databases/web sites and bioinformatic tools. The wishes of the respondents are in contrast to the libraries' view about bioscientists interest concerning bioinformatic databases/web sites and bioinformatic tools.
Detektion av Trichomonas vaginalis samt Mycoplasma genitalium med multiplex realtids-PCR : En prevalensstudie i Jönköpings län
Beställningsfrekvensen för detektion av Trichomonas vaginalis samt Mycoplasma genitalium i Jönköpings län är låg jämfört med den för Chlamydia trachomatis och Neisseria gonorrhoeae. Både T. vaginalis och M. genitalium har associerats med infektion av humant papillomvirus (HPV) samt kan bland annat orsaka salpingit med infertilitet som potentiell komplikation. Patogenerna har även beskrivits öka risken för transmission av HIV. Syftet med studien var att detektera T.
Rumslig fördelning av grov gammal tall i Uppsala stad med tallticka som indikator på höga naturvärden :
Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning.
The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.
Exkursion ? ett lärandetillfälle? : Lärare och elevers uppfattningar om exkursioners betydelse för lärande i ekologi
The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning. Open questionnaires and half structured interviews were used to investigate this. Persons who answered the questionnaires and participated in the interviews were senior high school teachers in biology or science and high school science students. All the teachers and most of the students thought that field trips in ecology resulted in increased learning.
Bevarande av naturvärdesträd i enlighet med FSC och Holmen Skogs naturvårdspolicy :
In the end of 1998 the company Holmen Skog AB was certified accordint to the FSC system
with an area of 1 036 000 hectare. After that Holmen Skog AB has been working actively
with the nature conservation in the forestry. In order to control the quality of the company?s
nature conservation in final fellings they started a yearly inventory which is called BAKRUS
(Judgement of ecological and culture care in relations to policies for a persevering
silviculture). After 1999 the control was expended to include all actions in the forest.
Etiska aspekter av preimplantatorisk genetisk diagnostik och genterapi
The research in the field of biotechnology is rapidly developing all over the world. Modern biotechnology offers unique opportunities, simultaneously as it gives rise to a number of ethical issues. Preimplantation genetic diagnosis (PGD), PGD/HLA (Human Leucocyte Antigen) and germline gene therapy (GLGT) are controversial techniques. PGD gives a possibility to identify a genetic disease prior to the embryo?s implantation in the uterus.
Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014
As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.
Flygbildsanalys av trädskiktets status efter brand : en metodstudie
During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future.
I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection.
Included in the study are four areas, three of which burned in 2005 and one in 2006.
