Foundations of variation in male aggressiveness and tolerance between chacma baboons (Papio ursinus) in Botswana and Guinea baboons (P. papio) in Senegal
(2014-10-24)The fitness limiting resource for most male primates is the indivisible fertilization of females. Therefore, males commonly compete aggressively with each other over access to receptive females. Among species, however, ... -
Feeding competition in wild female Assamese macaques (Macaca assamensis)
(2014-09-30)Food is one of the most important resources animals compete over and assessing the way individuals compete over such limiting resources is fundamental to our understanding of the adaptations of living organisms. In mammals, ... -
Female social relationships among wild Assemese macaques (Macaca assamensis)
(2014-07-14)It has been repeatedly shown that strong, affiliative social relationships (hereafter “social relationships”) are extremely important for human health and well-being. Increasingly there is evidence that non-human species ... -
Within- and between-group feeding competition in Siberut macaques (Macaca siberu) and Assamese macaques (Macaca assamensis)
(2014-02-26)Feeding competition remains of research interest as it affects growth, survival and reproductive success of individuals. It also limits group size and shapes the social structure of animal groups. Feeding competition is ... -
The social system of white-breasted mesites (Mesitornis variegata)
(2014-01-16)Animals show great diversity in their social systems, ranging from species living solitarily to species living in highly complex social groups. This variation in social systems provides the perfect setting to investigate ... -
Visual, Olfactory, and Vocal Cues to Fecundity in Human Females
(2013-12-13)Evolutionary psychologists argue that human males have evolved preferences for certain female characteristics that signal youth and health and consider them attractive. While menstrual cycle studies demonstrated changes ... -
Das Leben in der napoleonischen Armee - interdisziplinäre Untersuchung eines Massengrabs aus Kassel, Hessen
(2013-10-25)In 2008, a mass grave was found on the grounds of the University of Kassel, Germany. There was no evidence helping to identify them or throwing light on the cause of their death. Mainly due to 14C age determination and ... -
Cooperation and competition in wild male Barbary macaques (Macaca sylvanus) in Morocco
(2013-10-07)Mammalian males compete for a non-sharable resource (receptive females) and are typically the dispersing sex, thus cooperation between males may appear counterintuitive. However, if both partners gain mutual benefits from ... -
Biodiversity of true lemurs (Eulemur spp.): - Species delimitation and phylogeography in the brown lemur complex
(2013-09-26)Species are the fundamental units of comparison in all subfields of biology. Moreover, species are the currency of biological classification and used to define areas of conservation priority. Hence, central questions of ... -
Effects of forest fragmentation on brown spider monkeys (Ateles hybridus) and red howler monkeys (Alouatta seniculus)
(2013-09-13)The increasing intensity of anthropogenic land use and conversion has immense impacts on ecosystems worldwide and often results in habitat fragmentation. Fragmentation and other anthropogenic disturbances (e.g. hunting and ... -
Vocal Communication within the Genus Chlorocebus: Insights into Mechanisms of Call Production and Call Perception
(2013-09-11)It is difficult to overestimate the influence of language in day to day life, and language is often proposed as the clearest feature to distinguish us, Homo sapiens, from all other animals. The origin of language has long ... -
The Social System of Guinea Baboons (Papio papio) With a Focus on Male-Male Relationships
(2013-07-26)Understanding the driving forces in human social evolution is still a major aim in anthropological and primatological research. Baboons (Papio spp.) have traditionally served as a model in this context. Originating in ... -
Sex-specific differences in dispersal propensities and their consequences for grey mouse lemurs (Microcebus murinus)
(2012-10-22)Dispersal, the permanent relocation or change of social group of an organism, is an almost ubiquitous phenomenon among taxa. Sex-biased dispersal (SBD) propensities and/or distances are of one of the most common general ... -
Social organisation and mating system of the fosa (Cryptoprocta ferox)
(2012-09-24)Mammalian mating systems are closely related to the social organisation of a species, which in turn is determined by sex-specific selection pressures with respect to access to limited resources. In previous studies of ... -
Determinants and outcomes of group coordination and decision-making in red-fronted lemurs (Eulemur rufifrons)
(2011-10-07)In order to reap the benefits of group-living, gregarious animals have to maintain group cohesion. However, differences among group members in terms of sex, age or physiological constitution ... -
The effect of visible skin condition on the perception of female facial age, health, and attractiveness
(2011-09-14)Evolutionary psychologists argue that humans have evolved preferences for those facial features that signal health and fertility and thus facilitate mate selection. While there is ample ... -
The socio-endocrinology of female reproductive strategies in wild Assamese macaques (Macaca assamensis)
(2011-08-29)Sexual conflict is a prominent feature of animals living in multimale-multifemale groups, and drives the evolution of sex-specific reproductive strategies. Owing to divergent reproductive ... -
Phylogeny of Gibbons (Family Hylobatidae) with Focus on Crested Gibbon (Genus Nomascus)
(2010-05-10)Although the phylogeny and phylogeography of gibbons (Hylobatidae), a primate family endemic to Southeast Asia, has been studied in detail, phylogenetic relationships among taxa remain ... -
Variation in susceptibility to parasite infection: patterns, determinants and consequences in red-fronted lemurs
(2009-10-05)Parasites and infectious diseases represent an ecological force shaping animal social evolution. Particular attention has been paid to parasite infection as a driver of mate choice in models ... -
Beeinträchtigung und Selbstwirksamkeitserwartung bei chronischen RückenschmerzpatientInnen
(2009-08-21)Many studies with chronic low-back pain patients have proved how important the extent of disability is concerning the prognosis and the treatment outcome. However, there are different ...
