Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate Environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of Environmental enrichment.

That animals should be able to express their natural behaviours, even in captivity, has become a more important issue lately. Nowadays Zoos work much more with educating people and helping conservation projects for endangered species. This is two important reasons for making the environment as natural as possible for zoo animals. Both in captivity and in the wild capuchin monkeys have been seen to use tools such as stones and sticks to get food and are therefore seen as a natural and important behaviour for them. This study was carried out to evaluate a specific sort of Environmental enrichment where a group of three capuchins had to use sticks to get different kinds of food out of bottles.

The aim with this study is to prepare for a larger study, by gathering information about hunting enrichment, discuss which enrichment Parken Zoo in Eskilstuna have that are suitable to use in the larger study and report which observation methods that are used in other articles. In the larger study, the focus will lie on evaluation methods and measurable results. They have, during several years at Parken Zoo in Eskilstuna, developed different types of hunting enrichments for their carnivores, because hunting is a natural behavior that is hard to accommodate in captivity. The bigger project will integrate other zoos so that they can do a study on a larger group of animals, and because a lot of other studies in the same field only capture the results of few individuals. In this literature study you will read about the goals of enrichment, research that have been done on enrichment for felids and review several specific articles about hunting enrichment for felids..

It is often challenging to create a new enrichment program for any animal. This is especially true with the additional challenge that I wanted to use only naturalistic enrichment, and I?m working with animals some of which are nocturnal. Even with a many hurdles, a little bit of enrichment can do a big difference and make a big difference in activity levels of the animals. Eskilstuna parkens zoo have a house called the MUSeum housing four kinds of rodents.

Unjustified enrichment is used as legal basis when a part claims compensation. Unjustified enrichment can be illustrated as: (A) made a profit on someone else?s loss (B) and if the profit is"unjustified"and has"no legal basis"it shall be returned, which then make it possible for B to claim compensation from A referring to the profit. B has in this case lost something that he owns. To be able to claim A for compensation must the loss of B also be a benefit for A.

SummaryUnjustified enrichment is an obvious part of the jurisprudence in the majority of countries in Europe. But not in the Nordic countries, and certainly not in Sweden. This depiction of the Swedish posture is based mostly on Hellner?s thesis from 1950. A lot has happened since then, not to mention Sweden?s entry in to the EU.

Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.

This thesis analyzes the effects of different fertilization strategies on forest management at Holmen Skog in Umeå district. Harvesting volumes, net present values and fertilization intensity are presented for each fertilization scenario. The planning reserve (percentage area older than minimum final felling age) was also analyzed in this study.The thesis covers the analysis of five different fertilization scenarios, varying in fertilization intensity, from no fertilization at all, to fertilization at every harvesting operation (thinning or final felling). A sub-study was also carried out so the reader in detail can see how the different fertilization scenarios affect individual forest stands of different nature. The analysis has been done with the planning tool PlanWise, which is an application of the Heureka analysis and planning system.

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.

The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.

The Swedish government decided in 1996 that the governmental authorities are to implemementenvironmental management systems. Each year, the Swedish Environmental ProtectionAgency compiles the authorities? reports on their environmental management systems. Thecompilation shows that not more than 20 % of the authorities perform environmental audits.This study aims to investigate the authorities? view of internal environmental audits, the incentivesof performing them.

The world's natural resources are constantly being reduced, which increases the pressure on companies to actively engage themselves in environmental activities. Meanwhile, stakeholders focus is being broadened and it is now important not only to supply a particular product or service but also show that they are actively pursuing an environmental agenda. Companies can use various tools to aid in environmental efforts, but also to demonstrate to the world that the company is actively engaged in environmental activities. One such tool is the environmental standard ISO14001 which provides the company with guidance and support on how the business must manage its environmental efforts. To show a business' progress in environmental performance, it is advantageous to use environmental performance indicators as they enable stakeholders to easily understand how the business works with environmental issues.Authors in the field explain that the environmental management system propagation is limited in service organizations.

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).

Today?s political debate on environmental issues and environmental thinking, alongside the Swedish presidency of the EU and Climate Conferences shows that the environment is an important topic. Environment is important, not only in politics, but also for companies and the demand of environmental strategies and environmental reports has increased. This leads to an increased pressure on firms to begin to report on environmental concerns and to create active systems for environmental thinking.The aim of the present study is to examine why firms in the transport sector, mainly lorry transports, reports environmental aspects and what drives these companies to create these reports.Based on stakeholder and institutional theory we aim to examine to which extent stakeholders affects the environmental accounting and reporting. We also aim to explain how the organization is influenced to incorporate external and societal environmental procedures.
