Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek

The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

Do prey-animals in zoos need predators?

Today is one of the goals with zoos to conserve endangered species and some animals may also become reintroduced. But behaviours can change in generations of captive animals because of environments that differ from the wild. Animals must then be prepared before being reintroduced and predator training enhances the animal?s chance to survive in the wild. When training animals to avoid predators it is often necessary to use frightening stimuli.

Förpackningslogistik på Haldex Traction Systems AB

the most obvious problem at Traction today is the in-between handling that demands much time and resources. The reason is that the packages are not designed with handling in mind. Several of the packages of today also have a poor degree of utilization that means there is room for a fewer number of articles. That in turn means more packages, more transports, more storage space and more staff. On the basis of a specification of demands ? which take quality and environmental influence, as well as transport, handling and economy in account ? we have developed suggestions on new packages that will facilitate handling and lower the total costs, The time of handling will in some cases abbreviate to just a few seconds with the new packages.

Activity patterns of snow leopards (Panthera uncia) at their kill sites

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.

Klövspaltsinflammation : bakteriologi, terapival och möjliga anledningar till terapisvikt

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.

Comparison of two methods for evolving recurrent artificial neural networks for

n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.

Movement patterns of snow leopard (Panthera uncia) around kills based on GPS location clusters

The possibility of applying Low Stress Stockhandling in reindeer

The purpose of the study is to investigate the interest in Sami reindeer herders to use the Low Stress Stockhandling (LSS) method for handling reindeer. Also to find out which reindeer handling situations they think works the best and the worst, and which might need improvement. The purpose of LSS is to reduce the stress animals are subjected to during handling by creating consistent and calm responses from the animals. This is done by handling the animals through the animals? point of view and using natural herd behavior to accomplish this.

Predation som selektiv kraft bakom differentiering av populationer av sötvattensgråsugga, Asellus aquaticus

Predation is a strong dective force on invertebrate prey. Asellus aquaticus differs in pigmentation reed and submerged vegetation habitats in lakes. Light pigmented individuals al vegetation dominated by Chara sp. while dark pigmented individuals dominate in the reeds. These differences have been hypothesized to result from background matching.

Dokumenthanteringssystem inom byggbranschen

One of the aims of this report has been to make an inventory of the building trade market to see which document handling systems that are available. The secondary aim was to document the users´ demands on the systems and other demands such as quality assurance. After this, the document handling systems Byggnet and Lotus Notes, which are rather complex systems, have been analysed. Finally a recommendation has been made. In the inventory of the marketthe internet has been used because it is there the latest information can be found.

 Förståelse i handling : En essä om en resa från förståelse i ord till förståelse i handling

En serie dialogseminarier har genomförts med 5 företagare som deltagare. Syftet var att un­dersöka om det var möjligt att med dialogseminariemetoden lyfta fram denna yrkesgrupps yrkeskunnande. Det resultatet nådde jag inte. Jag tolkar orsakerna som att jag inte hade till­räcklig förståelse i handling av flera av de kritiska elementen som jag hade behövt behärs­ka för ett lyckat genomförande. Min intellektuella förståelse räckte inte till.

Purpose: The purpose of this master thesis is to help Clarkson Inc. adapt their information handling to modularity and to extract theories, methods and tools to guide companies in similar situations.

Hanteringsmetoder av reptiler på djursjukhus med hänsyn till stress och skaderisker

It is popular to keep reptiles as pets in Swedish households. The number of households reporting reptile ownership is more than 15 000 (SCB, 2006). This means that a veterinary practice should consider how to take care of reptiles as patients. The aim of this study was to examine literature and studies concerning safe handling and restraint of reptiles as well as the effects of acute and long term stress response and to suggest a simplified plan for handling reptiles in a veterinary practice. The result of literary studies is that common recommendations for safe handling and restraint of reptiles is based on old techniques and experiences from safe handling of wild animals. The main concern is safety for the veterinary nurse and for the reptile. Stress studies indicate that acute stress response is not harmful for the animal i long term. On the other hand studies of the effect of prolonged stress are not conclusive.

Omvårdnad av kanin på klinik : en litteraturstudie

Pet rabbits are increasing in popularity and the owners want the same treatment for them as they would want for a dog or a cat. However, the knowledge among clinical staff about these small animals is not always up to date. The aim of this paper is to highlight the needs of the pet rabbit and how these can be met regarding veterinary nursing. Pet rabbits are different from dogs and cats in several ways and their needs as patients differ as well. Rabbits are herbivorous prey animals. To avoid predators, they are very reluctant to show any sign of weakness for as long as they can.

Skrubberavfall : Hantering i hamn

This paper deals with challenges associated with handling scrubber waste in the port of Karlshamn and what various industry partners are doing to meet this growing demand. The main challenges have been the proportion of ships with scrubber, the amount of generated waste and waste characterisation. An understanding of these factors has been crucial in order to ascertain the aim of this study, which has been made with calculations based on leading manufacturer?s scrubber analyses and with an estimation of the quantity of ships with scrubber by examining AIS data from the Port of Karlshamn. In order to calculate the quantity of scrubber waste two different scenarios were established, which in turn produced two different outcomes.
