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.

Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use

The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

Studier av insolvensförordningens artikel 5 : -särskilt om sakrättsbegreppets betydelse för borgenärer med företagshypotek

Bullying is today a major problem in schools worldwide. Far too many children are forced to undergo bullying day in and day out without anyone seeing or doing something. My purpose with this study is to find out how four F-6 schools in a municipality south of Stockholm are describes their work to get zero tolerance for bullying at their school.My questions are:How does the four F-6 schools' anti-bullying group in a municipality south of Stockholm describes their work to have zero tolerance for bullying?What do the employees in the school anti-bullying groups consider that bullying is?Why do the employees in the school anti-bullying groups think bullying occurs?Who do the employees in the school anti-bullying groups think are bullies or are being bullied?To get my results I have done four interviews with those in charge of the school's anti-bullying group. My theory is based on standards, what is acceptable behavior and normative theory, hypotheses, what is right and wrong as well as desirable or undesirable behavior.

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.

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.

Brunbjörnens (Ursus arctos) inverkan på den nya svenska älgförvaltningen

The European Brown bear (Ursus arctos) has gone from basically being extinct in Sweden to, 2008 being estimated to a total of 3298 individuals. When looking at the new Swedish moose management system it is important to have an ecosystem-based approach and therefore include all the parts that moose impacts on and from in the management, especially the brown bear. Primarily in the spring and early summer the brown bear is a significant predator on moose calfs which must be taken into account in moose management. When the bear recolonize areas that it has previously been eradicated from, it will once again come in contact with people who are not accustomed to the bear's role in the ecosystem. We studied three groups of moose management areas with different predation by bears.

Fisk- och fågelpredations påverkan på den bentiska makroevertebratfaunans sammansättning under tidig vår i Tåkern

Predation is one of many factors that form the structure of the macroinvertebrate community in lakes, wetlands and watercourses. Earlier studies lack an examination concerning how fish- and waterfowl predation affect macroinvertebrates during shorter periods in the spring. I performed an exclosure study in the shallow eutrophic Lake Tåkern which is located in the western part of Östergötland County, Sweden. The experiment was performed during a three week period (1-21 April 2012) when the water temperature was low and the density of migrating diving ducks was high. The experimental cages used included three out of four different treatments; general predation (open cages), bird exclusion (net with mesh size 90*45mm) and no predation (net with mesh size 1*1mm).

Tecken : En retorisk-semiologisk analys av antirökreklam

This essay studies how advertisements in various anti-smoking campaigns can influence and persuade by using anti-logos as counter-arguments to the tobacco industry's logos. In contrast to tobacco advertising arguments such as freedom (logos), pleasure (pathos) and trademark (ethos) the anti-smoking campaigns create anti-logos arguments with various connotations such as repulsive pictures and sexual implications to influence groups of people not to start smoking or to quit smoking.Advertisement of tobacco does not exist nowadays due to legal restrictions in the western world; however several decades of myths created in the consumer consciousness still exist. Thus one can speak of a tobacco advertising ideology that exists and the various anti-smoking campaigns trying to change that ideology.The purpose of anti-smoking campaigns is to conduct a kategoria of myth that tobacco advertisement has created over the years. Anti smoking organizations do this by creating a new ideology to affect consumer?s attitude toward smoking and the tobacco myth with an anti-myth.

Predation av sandräka (Crangon crangon) på juvenil piggvar (Psetta maxima) och juvenol skrubbskädda (Platichtys flesus) : betydelse av yngelstorlek för överlevnad hos piggvar och skrubbskädda efter bottenfällning

Turbot (Psetta maxima) and flounder (Platichthys flesus) are two species of flatfish both having their nursery areas around the shores of Gotland in the Baltic Sea. The common brown shrimp (Crangon crangon) is a known predator on newly settled plaice (Pleuronectes platessa) in the North Sea area and is also found in the Baltic Sea. Experiments were carried out to see if the brown shrimp is predating on juvenile turbot and flounder, and if so on which sizes, and if the brown shrimp prefers any of the flatfish species, and also to see if there is a difference between day and night in density of the shrimp, i.e. when the fish might be subjected to predation. The results showed that predation decreased with size for both turbot and flounder.

Rovdjurens påverkan på den svenska älgstammen och konsekvenser för dess förvaltning

Den svenska älgstammen har i stort sett levt i frånvaro av björn och varg under större delen av 1900-talet. Istället har stammen reglerats genom en intensiv älgjakt. Nu har både björn och varg återetablerats i våra skogar och expanderar i antal och utbredning. Syftet med denna studie är att ta reda på hur återkomsten av dessa stora rovdjur påverkar älgstammens antal, köns- och åldersstruktur och beteende, samt hur älgförvaltningen påverkas av närvaro av björn och varg. Rovdjursstammarna är ojämnt fördelade över landet och även älgtätheten varierar. Därför kommer en del områden att påverkas mycket och andra väldigt lite.

I strävan efter anti-estetik och musikalisk etik

In his master thesis, Johan Jutterström pursues an anti-aesthetic and ethic artistic process. He?s using mainly three different strategies; reasoning through text, composing for ensemble, and solo improvising on the saxophone. Through composing the piece for 12 musicians Trästolen, Jutterström tries to erase himself and his taste from the music. In that endeavor he looks to physics as a catalyst.

Say no to racism?: FIFAs antirasism ur ett postkolonialt perspektiv

The purpose of this thesis is to historically describe how Fédération Internationale deFootball Association (FIFA) interprets how the discourse of anti-racism has developed withintheir own organization throughout the years. In doing so, the thesis lands in a present timeperspective and then aims to identify the norms which FIFA, according to the organizationitself, stands for in regard to anti-racism within world football. That standard of behavior isthen put in contrast with the hidden ideological conceptions which, with the applying of apost-colonial perspective, can be found in the rhetoric used by FIFA in expressing themselvesabout their anti-racism stand.The methodology used in this thesis builds upon a qualitative text analysis approach inwhich solely primary sources available through the official website fifa.com are considered.The study finds that anti-racism is a relatively young concept within FIFA and that the communicatedideal standard of behavior circles around terms such as unity, diversity, solidarityand equality. Further on, FIFA clearly articulates how the universal power of football as suchcan unite people and that FIFA, as the administrator of this the world?s greatest sport, can setan example for the rest of the world to follow when it comes to notions of tolerance and solidarityin preventing racism in the future.In following the terminology provided by the post-colonial theorists Homi Bhabha andGyatri Spivak, and applying the concepts of fixity and essentialism on the rhetoric aroundanti-racism, the study discovers that FIFA, in sharp contrast to the articulated norms, in factexpress ideological conceptions of skin as a barrier of difference between people, and thatFIFA on good grounds can be accused of reproducing racist stereotypes rather than bridgingthem.The study concludes that its findings clearly demonstrates the increased need of consideringsports, and more specifically international sport organizations, as a basis for researchwithin the academic field of International Relations, and that a postcolonial perspective verymuch can provide alternative understandings of how these actors operate and what influencethey might have in the international system..
