Assessing sociality: catarrhine microsatellites and the dynamics of glucocorticoids with social relationships in wild male Assamese macaques (Macaca assamensis)
(2024-02-22)In order to navigate within-group competition and maximise fitness, strategies have evolved in group-living animals, including social dominance ranks and affiliative relationships. Both of these play a crucial role in ... -
Microsatellites and Genetic Variation in Two Members of the African Papionini
(2023-03-31)The importance of genetic variation for the fitness and viability of populations and species has been shown in many studies over the last decades. However, the way to determine such genetic variation has changed and evolved ... -
Genetic and behavioral correlates of pair living in coppery titi monkeys (Plecturocebus cupreus)
(2021-02-15)The occurrence of monogamy in mammals represents an evolutionary puzzle. Because of reduced parental investment, males are expected to increase their reproductive success by mating with multiple females rather than being ... -
Mating behaviour of a wild olive baboon population (Papio anubis) infected by Treponema pallidum
(2020-10-01)According to the World Health Organization (2019), more than one million sexually transmitted infections (STIs) are acquired every day worldwide in the human population. These infections can have serious reproductive health ... -
Investigating the neural processes underpinning the production and anticipation of stuttering in Adults who Stutter
(2019-02-04)Stuttering is a disorder of speech production, characterised by physical disturbances that compromise fluency. Persistent developmental stuttering is a speech fluency disorder defined by its symptoms, where the underlying ... -
Visual information processing, welfare, and cognition in the rhesus macaque
(2017-10-20)Visual information processing, welfare, and cognition in the rhesus macaque - Chapter one deals with motion and disparity in macaque monkeys' area MST and their functional independence. Chapter two relates with the advantages ... -
Processing of Graded Signaling Systems
(2016-03-24)Vocal repertoires of nonhuman animals and especially of terrestrial mammals are often characterized by their relatively small size of innate vocal types which can show considerable variation in acoustic structure. To ... -
Gene flow dynamics in Baboons - The influence of social systems
(2015-09-04)The relationship between genes and behaviour has been of longstanding interest to evolutionary biologists. Certain behaviours can shape the genetic structure of natural populations, thereby altering their genetic diversity ... -
The influence of attention on motion processing
(2013-10-25)This thesis examined the influences of attention on the processing of complex and simple motion stimuli. The work consists of two physiology studies. In the first study we investigated the question of how complex motion ... -
Phylogeography and impact of hybridization on the evolution of African green monkeys (Chlorocebus Gray, 1870)
(2013-06-04)The evolution of the current global biodiversity has been profoundly influenced by climatic and environmental changes over the past million years. While there is an obvious impact of Quaternary climate changes and glacial ... -
Taxonomy and Phylogeny of Leaf Monkeys (Colobinae) with Focus on the Genus Presbytis (Eschscholtz, 1821)
(2012-08-07)Leaf monkeys (Colobinea) constitute a very diverse group of primates with major radiations inAfrica and Asia. Among the langur group, Presbytis constitutes a particular diverse taxon. Based on molecular biological and ... -
Genetic interaction of Per- and Dec-genes in the mammalian circadian clock
(2011-12-07)Many behavioural and physiological processes in mammals display circadian (24 hour) rhythms controlled by an internal timekeeping system the circadian clock. The pacemaker of the circadian ... -
Cortical and subcortical mechanisms of persistent stuttering
(2011-02-16)The causes and underlying pathomechanisms of persistent stuttering have been obscure for a long time. Recent neuroimaging studies suggest a maladaptive cortical and subcortical morphology ... -
How introgressive hybridization shaped a genus' phylogeny
(2010-06-24)Primates are a diverse order, which exhibits numerous behavioral and morphological traits. To elucidate the evolutionary history of those traits an understanding of the phylogeny of the ...
