Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole

Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.

Fodertillgång och stereotypa beteenden under natten hos Asiatisk elefant (Elephas maximus)

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.

Virtuella doftspår på webbplatser

Människan är nyfiken och vill finna ny information på webbplatser. Detta kan underlättas med hjälp av virtuella doftspår som användaren följer. Denna rapport är en fördjupning i hur människan går tillväga för att följa virtuella doftspår och hur man som designer ska använda sig av detta när man utvecklar en webbplats. Genom teorierna information foraging och användbarhet har en användbarhetsmodell och en operationalisering tagits fram för att underlätta detta. Tillsammans med datainsamling genom intervjuer och metoderna heuristisk utvärdering och high fidelity har studien visat att när man skapar ett gränssnitt för användare behövs information foraging som bestämmer eller lämnar förslag på hur virtuella doftspår påverkar användaren..

"Bara att gilla läget" : Ungdomar i Södermöre och förhållandet till centralorten Kalmar

The purpose of this essay has been to find out how adolescents from Södermöre in the municipality of Kalmar experience the central place Kalmar. It has also been the intention to make clear, whether the relation between the adolescents and the central place Kalmar could be described as a centre-periphery-relation. The basis of this essay has been interviews of all together nine adolescents.A centre-periphery-situation can according to the theory be discovered by analyzing three categories: culture, economy and politics. If the centre dominates the periphery in one of these three categories, a centre-periphery-situation exists. The theory also says that the people living in the periphery experience less kinship with the people living in the centre.The adolescents from Södermöre showed to experience the central place Kalmar in a way, that can be described in five categories: travelling mostly by bus, unfair distribution of the resources of the municipality, political equality, social equality and the awareness of the central place Kalmar as the place ?where everything is located?.When it came to economy and politics, no indications of a centre-periphery-situation were found during the interviews with the adolescents.

Wolf movement patterns and the distribution of moose kills : implications for human harvest?

Most studies regarding wolf (Canis lupus) predation on moose (Alces alces) have focused on the total annual consumption of moose within a wolf territory but few have tried to describe the spatial impact of wolf predation on a local scale. In this study I have analyzed wolf movement data, wolf predation, moose hunting statistics and moose hunter observations to investigate how wolf predation affects the human harvest of moose in Scandinavia. Since wolves prey on mostly juvenile moose during summer, analysis of their summer movement patterns is crucial to understand its impact on the human harvest later during autumn. In this study both reproducing (n = 45) and non-reproducing wolves (n = 12) reduced their movement range during summer to 66% and 67% of their annual movement range, respectively. Reproducing wolves increased their movement range from early to late summer while non reproducing wolves did not.

En analys av foderkostnader i mjölkproduktion

Animal welfare is impaired if the diet does not provide sufficient feeling of satiety or the ability to perform natural feeding behavior. Pigs are omnivores and spend most of the day searching for food by rooting, grazing and chewing. Both inability to perform foraging behavior and insufficient feeling of satiety often leads to direction of foraging behavior towards stereotyped and abnormal oral behavior. Dry sows are often fed restrictively which leads to unsatisfied feeling of hunger. Dietary fiber has been found to reduce stereotypic and abnormal behavior as well as aggression, which could indicate that pigs need to forage has been met giving a feeling of satiety.

Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)

The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.

Habitatval, migrations- och furageringsaktivitet samt homing hos gädda (Esox lucius) härstammande från Österby myr, Gotland.

In this study the spawning migration activity, habitat choice (depth and temperature), foraging activity, duration of stay in the spawning site and homing-behavior was studied for anadromous pike (Esox lucius) in the wetland Österby myr, Gotland.The spawning migration was concentrated to dusk and dawn, a homing behavior was confirmed and there was no significant difference between sexes with respect to duration of stay. A difference in habitat choice and small variation in foraging activity between individuals was established..

Plats och minne

Place as a concept, and memory as a phenomenon is researched through literature studies. The essay investigates how we think about place and how we experience and relate to it. Memory is discussed both as personal memory and collective memory. Place is a strong source of memory. When we return to a place, we recognize not only the place itself, but also the things we did there, the people we met and the thoughts passing through our mind when we last were there. Pieces of ourselves are stored in the memories awaken when we revisit a place.

Mellan stad och hav - kajpromenad i Kalmar

The aim of this project is to investigate the meeting between the city and the sea and tolook into how that could be developed and made use of. I want to find out how you can increase the availability of a specific place and make it more welcoming, I also want to bring life to an already existing space and create a central meeting place in the city. The purpose is to give form to an esplanade along a dock in the central parts of Kalmar. Starting with an analysis of this public place, I want to create a concept that is close to the existing context and communicates the contrasts or associations between for example: city and nature, artificial and natural and indoor and outdoor. The primary object of the project is to add a welcoming, public place to the city where you on an accessible way canfamiliarize yourself with the meeting between the city and the sea.

Att vara i Vara kommun : En studie om kommunens identitet, profil och image

Abstract The aim of this paper is to investigate whether Vara municipality has a continuous picture of their identity, profile and image. Globalization has contributed to the increasingly growing of place marketing. Therefore, the study goes on to using the concepts of identity, profile and image to find out if Vara Municipality communicates similar throughout the whole organization and find out their all through core values. Globalisation will be an interpretive framework for the work that describes why the place marketing is becoming more pressing. The sense of place will be a central part of this study as it is the feelings and images of different places that will be described by the municipality together with the identity, profile and image.

Ett nytt ansikte utåt : Ett arbete om utveckling av en B2B-sajt med en kombination av olika metoder och principer.

Företag som bedriver handel via nätet på sajter som inriktar sig mot privatpersoner satsar idag mycket på att utvecklas för att på bästa sätt stödja kunden mot sitt mål. Dock har företag som inriktar sig mot andra företag (B2B-business to business) inte hängt med i samma utsträckning. Den här rapporten syftade till att undersöka hur man kan arbeta för att ta fram ett designförslag på en B2B-sajt, närmare bestämt vilka metoder och teorier man kan dra nytta av. Metoder och teorier som har använts är effektkartläggning, Coopers målinriktade designmetod, Nielsens designprinciper för användbarhet och information foraging. Arbetet resulterade i en prototyp kring vilken en diskussion fördes följt av slutsatsen att valet av metoder och teorier tycks vara en lämplig kombination vid utveckling av B2B-sajter men att ytterligare forskning krävs för att skapa en enhetlig metod..

Bibliotekscaféet som place: En användarstudie om bibliotkscaféer på folkbibliotek

The aim of this study is to investigate the meaning of the librarycafé for its visitors as a place. By this study we want to see howimportant the library café is as a place. Our theoretical departurepoint is an adaption of the space and place-theory, by Fisher,Saxton, Edwards & Mai. By adapting the theory to a libraryperspective it helps us to understand how library users look uponthe library café as place.Using a qualitative approach the empirical material has beencollected through observations and interviews. We observed andcarried out interviews with six library café visitors at threedifferent library cafés.Our findings are that the library café is used in many differentways and by many different peoples.

Diurnal rhythm of the savannah elephant (Loxodonta africana africana) in Maasai Mara National Reserve, Kenya

Elephants are hindgut fermenters, which affects their diurnal rhythm. To reach their nutrient demands, elephants must eat almost constantly throughout the light part of the day. Sexual dimorphism may also affect their behavioral patterns. To understand the elephants' normal living habits and foraging behaviour, we conducted a pre-study in the Mara Triangle, the north-western part of the Maasai Mara National Reserve. Each of four to six observers randomly chose a focal animal within the group of elephants by the criteria that they were adults and visible.
