The effects of mother trees and site conditions on the distribution of natural regeneration establishment in a Bornean rainforest disturbed by logging and fire

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor

Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. Detta lämnade stora ytor av Borneos skogar i ett undermåligt, sekundärt tillstånd. På grund av detta startades INIKEA projektet med syfte att rehabilitera skogar i regionen kring Tawau vid östkusten av delstaten Sabah i Malaysia. I denna studie undersökte jag resultatet av rehabiliteringsarbetet på krontaket i tre olika skogstyper genom att ta hemisfäriska foton med en digital systemkamera (DSLR).

Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia

Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity. Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.

Ett flytande paradis? : En studie om hur tropiska öar framställs i svenska resemagasin

This is a study about how Swedish travel magazines write about tropical islands with a history of colonization. The study investigates how the islands of Mauritius, the Seychelles, Haiti, the Maldives, the Dominican Republic, Aruba, Zanzibar and Guadeloupe are being portrayed in four Swedish travel magazines.Travel articles published in the travel magazines Vagabond, Allt om Resor, Res and Escape 360° during the period January 2004 to December 2009 have been analyzed through critical discourse analysis.The study concludes that the travel magazines tend to idealize and aestheticize the tropical islands. The islands are being presented as paradises on earth. They are described as fairy tales, magical, dreams and as playgrounds for Westerners. The inhabitants of the tropical islands are being judged by how well they attend to the tourists? needs and wishes.

Konsumenters attityd till etiska och miljömässiga märkningar - möjliga förklaringar till "konsumentglappet"

Det blir allt vanligare med etiska och miljömässiga märkningar på livsmedel. Med bryggkaffe som exempel är syftet med uppsatsen att undersöka konsumenters attityd till symbolerna KRAV, Rättvisemärkt, Rainforest Alliance och EU-symbolen för ekologiskt jordbruk. Genom att undersöka attityden kan möjliga förklaringar till det så kallade ?konsumentglappet? urskiljas samt förslag till hur glappet kan minskas. Den teoretiska huvudmodell som använts är ?The ABC-model of attitudes? och som analysunderlag används positionering och valkriterier.

Grazing behavior of Ankole and Boran cattle in an improved herding production system

To be able to provide the growing human population with food, the productivity of the animals as well as land use needs to be improved and intensified. Hence, understanding the behavior of animals is crucial both for animal welfare and productivity as well as the management of the cattle. There are many factors affecting the grazing behavior of cattle in tropical conditions, such as human-animal interactions, herd management, breed, season and temperature. The purpose of this study was to investigate the grazing behavior of two tropical cattle breeds, Ankole and Boran cattle. Kenyan Boran belongs to a zebu type of cattle and is preferred to many other breeds due to the higher productive and reproductive capacity and adaptability to tropical conditions.

Inga kommentarer? Knappast. : En studie av deltagarkultur i läsardebatten i Helsingborgs Dagblads kommentarsfält.

In this thesis, the results of a survey regarding grade progression between secondary and upper secondary school in a municipality in the north of Sweden serve as the starting point for a study of the experiences and expectations of a number of 16 year old girls who are in the first year of upper secondary school. The study is performed by means of focus group interviews with female pupils from the three largest upper secondary schools in said municipality in an attempt to gauge their experiences of grades, grade assessment, teacher practices and perceived differences in how boys and girls are treated. The results show that most of the girls are disappointed with upper secondary school so far. Many of them feel that secondary school was both more fun and more rewarding in a sense of learning. Their appreciation of how this more rewarding atmosphere affected their grades differed between the various groups.

Idealets berättelse : hur etiska certifieringsorgan skapar sina identiteter genom narrativ

Konsumenter har tämligen lite insyn i omständigheterna kring produktionen av de varor de dagligen konsumerar. I en värld av global handel är det till synes oundvikligt att människor och miljö blir lidande när privata, vinstdrivna företag bara har intresse för just vinst, och statliga myndigheter inte mäktar med, inte har intresse av, eller helt enkel inte anses legitima, att lägga sig i de förhållanden under vilka världshandeln sker. Mot bakgrund av detta har mängder av så kallade NGO:s (non-governmental organizations) bildats för att certifiera varor som lever upp till de specifika organisationernas krav. Dessa organisationer tävlar sedan om konsumenters och finansiärers gunst. Denna uppsats undersöker frågan; Hur framställer märkningsorganisationerna Fairtrade, Rainforest Alliance, KRAV och UTZ Certified den egna organisationens verksamhet och målsättning? Dessa fyra organisationer har av olika skäl valts ut som exempel i denna uppsats.

Vilka faktorer påverkar konkurrensförhållandet mellan en kommunal och en fristående gymnasieskola : en jämförelse av gymnasieskolornas ekonomistyrning och verksamhetsstyrning

When the independent upper secondary schools were started in 1992, it meant a change in the competitive relationship for the local upper secondary schools. A reduced number of students during some years ahead, while the number of independent upper secondary schools increase will probably result in tougher competition between upper secondary schools.The purpose of this study is to review and compare financial and performance management between a public and an independent upper secondary school. The dissertation will focus on the now existing competitive relationship between the two types of upper secondary schools.The theory underlying the study is Porter's model - five competitive forces. The model is applied to the local upper secondary school and used to identify competitive factors affecting upper secondary schools. The study is using a qualitative approach with five interviews at two upper secondary schools, one independent and one public, located in the same town.The comparison of financial and operational management of upper secondary schools indicate that the differences are not as great as we first imagined, but that there still are some differences.

Historielärobokens användning : En studie om gymnasielärares användning av historieläroboken.

The aim of this thesis is to examine how secondary teachers in the subject of history are using the textbook in their teaching. Four questions are being dealt with in this thesis. What importance is being placed on the use of history textbooks by the secondary teachers? What priorities do the secondary teachers have? How do they deal with student interests? And what is the importance of the secondary teachers? work experience? I have interviewed four secondary teachers with different work experience to complete this thesis. A Dictaphone has been used in all the interviews. Research has shown that textbooks now have a central role in teaching and the lack of alternative materials and reduction of teaching hours has made it difficult to replace. The main conclusions of the thesis are that the history textbook has a dual role depending on the teacher you ask, and that the history book is used differently by the teachers.
