Breeding and morphological differences of domestic dog
Nový, Jakub ; Figura, Roman (advisor) ; Komárek, Stanislav (referee)
Dog (Canis lupus f. familiaris) is one of the oldest domesticated animals and he has been by our side for several thousand years. Although we know a lot of different domesticated animal breeds but by far it didn't reach such distinction in case of dog. In my work I'll be examinating domestication of this beast and its breeding. Also I'll be dealing with breeds of dogs and especially with morphological differences between them. Key words: Canis lupus familiaris, domestication, breedig, morphology, breed
Concept of body in Old Norse literature
Novotná, Marie ; Komárek, Stanislav (advisor) ; Horáček, Ivan (referee) ; Starý, Jiří (referee)
This work attempts to outline concepts associated with body in the Old Norse literature. As the word for the body (líkamr) as well as the term for an incorporeal soul (sál) do not occur in the Old Norse literature until the translated Christian works and cannot therefore be used as markers, two areas closely connected with the concept of body have been chosen for the research: shifting of shape (hamr) and somatic expressions of emotions. In the first area, i.e. phenomena associated with shape-shifting, contexts of all (113) occurrences of radix ham- in the Old Norse literature are analysed in order to describe the semantical field of this root. Within the themes that have appeared in the material (i.e. shape-shifting related to flying, battle frenzy and magic), occurrences are ordered on an axis from those where the form (hamr) is considered to be holistic to those where just the form of body or soul is described. In this context, it is important to mention the proximity of man and animal in the Germanic environment, as shape-shifting is often related to an animal and thus points to the limits of human identity. In the second area, i.e. somatic expressions of emotions, we can also find cases where the mental and the physical area intersect and the boundaries between diseases and emotions are not...
Evolutionary consequences of species specific learning strategies: importance of processes resulting in food aversion and special case of social transmission
Landová, Eva ; Fuchs, Roman (advisor) ; Komárek, Stanislav (referee) ; Sedláček, František (referee)
t t Summary This PhD. thesis contributesto the investigationof aposematism- the phenomenonexplaining occuÍTenceof warning coloration in nature. Aposematismis anantipredatorystrategyousuallybasedonpredatorlearning to avoid a noxious prey with a conspicuoussignal. However, not only particularaspectsof aposematicprey signalling (waming colour pattern, conspicuousness,unpalatability),but also predator'spsychologyleadingto avoidancebehaviouris animportantfactorin theevolutionof aposematism. The differentialspecies-specificresponseof nine speciesof our conrmon passerine birds to living aposematicprey (the ťrebug) and correspondingunderlyingvariationin predator'secolory requirements has beenstartingpointof thisPhD.thesis. The next partsof the presentthesishavebeenfocusedmainly on determinationof thesespeciesthat respondspositively (throughoutinnate biases,betterlearningor memoryetc.)to the warningsignalof aposematic prey. The diversity of psychological processes leading to avoidance behaviourin thesespecieshas beenassessed.Firstly, we investigateif the avoidancebehaviouris acquiredby learningor ifthe preyis avoidedon the basisof innatebiasesin severalspeciesof family Paridae. Thenwe focused onmodeof avoidanceleaminganddurabilityof acquiredbehaviourin model species(greattits).The changesin memoryfor...
