Causes and consequences of female competition in redfronted lemurs (Eulemur rufifrons)
(2024-04-19)Competition among female mammals appears to be much more widespread than previously thought, and it can take on extreme forms, including eviction and even death. Nevertheless, female competition has only recently been ... -
Evaluating morphological and metrical methods for sex estimation on isolated human skeletal material
(2023-02-13)The primary goal of this study is to estimate the sex of human skeletal materials using morphological and metrical methods described in the forensic and anthropological literature with molecular testing performed on Inden ... -
Genetische Diversität in der Lichtensteinhöhle – Ableitungen zur Demographie und Interpretationen zu sozialen Strukturen sowie Bestattungssitten in einer bronzezeitlichen Bevölkerung
(2022-03-03)The archaeological part of the Lichtenstein Cave, a gypsum karst cave in the southwestern periphery of the Harz Mountains, was discovered in 1980 and has since been investigated in close, interdisciplinary cooperation. The ... -
Environmental and maternal effects on infant development in wild Verreaux´s sifakas (Propithecus verreauxi)
(2021-12-23)Organisms’ life cycles vary tremendously between and within species leading to differences in life histories. Early development plays an important role in the life trajectory of an individual and shapes its entire life. ... -
Ancient genetic landscape of archaeological human remains from Panama, South America and Oceania described through STR genotype frequencies and mitochondrial DNA sequences
(2021-12-20)The settlements of the Americas and Oceania are particularly fascinating topics. On the one side is the settlements of Australia and New Guinea (30,000 – 50,000 years ago) were the scenarios of one of the earliest migration ... -
Energetics in wild female Assamese macaques (Macaca assamensis): a behavioral and physiological approach
(2021-08-16)Energy is a key requirement of life. It is involved in life history traits such as body maintenance, growth and reproduction. Energy is a limiting resource and therefore has to be strategically allocated. When facing an ... -
Measuring communicative complexity across modalities: a new framework in the context of the “social complexity hypothesis” and its application in true lemurs
(2021-03-25)Animals exhibit an astonishing diversity of communicative systems, with substantial variation in both the nature and the number of signals they produce. Variation in communicative complexity has been conceptually and ... -
A short story: senescence in an annual reptile, Labord’s chameleon (Furcifer labordi)
(2020-12-10)Among animals, the fast-slow continuum is the dominant axis that shapes life-history variation. As resources are limited a trade-off occurs between a short lifespan, young age at maturity, high reproductive rates and high ... -
Health consequences of group living in wild Verreaux’s sifakas (Propithecus verreauxi)
(2020-07-10)The evolution of sociality exposed individuals to several new health-related costs and benefits, which fundamentally affect their survival and reproductive success. Group living provides better access to food and mates and ... -
Historische Anatomieleichen der Universität Göttingen – Zur Morbidität einer Bevölkerungsgruppe des 19. Jahrhunderts
(2019-07-29)The work presented here deals with the results of the study on the morbidity frequencies of a population group of the 19th century In 2011, human remains of 159 individuals were recovered in a partial excavation on the ... -
Roots of Primate Cognition. The Primate Cognition Test Battery applied to three species of lemurs (Varecia variegata, Lemur catta and Microcebus murinus).
(2018-05-16)Compared to other mammals, primates have evolved relatively large brains and outstanding cognitive skills. Given that brain tissue is energetically very costly, one major evolutionary question concerns possible selection ... -
Conservation physiology of two closely related, sympatric lemur species, the fat-tailed dwarf lemur (Cheirogaleus medius), and the gray mouse lemur (Microcebus murinus)
(2017-10-30)The detrimental effects of human-induced habitat loss and degradation on wildlife are pervasive and represent a primary concern for conservation biologists. Understanding how organisms accurately recognise and respond to ... -
Evolutionary mechanisms shaping MHC variation in sympatric lemurs
(2016-11-15)The major histocompatibility complex (MHC) is a multigene cluster characterized by remarkable polymorphism and a complex evolutionary history. The MHC genes assume a central role in the adaptive immune response of vertebrates ... -
Immature development in wild Assamese macaques (Macaca assamensis)
(2016-10-11)Relationships between adult attributes and lifetime fitness have been previously explored in numerous studies, but although many adult attributes diversify during childhood or even prenatally, and although lifetime fitness ... -
The Chemical Ecology of Primate Seed Dispersal
(2016-04-06)Many tropical angiosperms rely on frugivores for seed dispersal and evolved fleshy fruits to attract them. Although both sides of the interaction are generalists, frugivores do not feed on the full range of fruit species ... -
Social organisation of the narrow-striped mongoose (Mungotictis decemlineata) in Kirindy Forest C.N.F.E.R.E.F., Madagascar
(2016-02-16)The diversity of ecological and behavioural adaptations of the Carnivora makes them an exemplary group for studying patterns of mammalian social evolution. In particular, species displaying sex-specific forms of social ... -
Intergroup relationships in Verreaux's sifakas (Propithecus verreauxi)
(2015-12-15)How animals achieve collective action for territorial defense and how they establish relationships between neighboring groups has recently become a central topic in the study of animal behavior. The power of a group can ... -
Sex-specific aging: Sex differences in survival and health in a wild primate population
(2015-01-15)Ageing influences the functioning of most living organisms in myriad ways and has profound consequences for their reproductive fitness and survival. Age-related changes in the functioning of an organism are thought to ... -
Behavioral and Feeding Ecology of a Small-bodied Folivorous Primate (Lepilemur leucopus)
(2015-01-13)Small-bodied folivorous primates are rare because processing leaves often requires extensive gut adaptations and lengthy retention times for fiber fermentation. However, Lepilemur leucopus (white-footed sportive lemur) ... -
Influence of social tolerance on social learning
(2014-11-10)One outstanding feature of modern human societies is the complex cultural behaviour they exhibit. Although we do not find comparable capacities for culture in other species, some elements of culture are present in the ...
