2021-06-16ZeitschriftenartikelEarly maternal loss leads to short- but not long-term effects on diurnal cortisol slopes in wild chimpanzees Girard-Buttoz, Cédric; Tkaczynski, Patrick J.; Samuni, Liran; Fedurek, Pawel; Gomes, Cristina; Löhrich, Therese; Manin, Virgile; Preis, Anna; Valé, Prince F.; Deschner, Tobias; Wittig, Roman M.; Crockford, CatherineThe biological embedding model (BEM) suggests that fitness costs of maternal loss arise when early-life experience embeds long-term alterations to hypothalamic-pituitary-adrenal (HPA) axis activity. Alternatively, the ...

2019-05-16ZeitschriftenartikelElevated neopterin levels in wild, healthy chimpanzees indicate constant investment in unspecific immune system Behringer, Verena; Stevens, Jeroen M. G.; Wittig, Roman M.; Crockford, Catherine; Zuberbühler, Klaus; Leendertz, Fabian H.; Deschner, TobiasBackground Ecological immunology proposes that the optimal immune defence, and the costs coming with it, vary across environments. In environments with higher pathogen load, the immune system should experience greater ...

2020-01-07ZeitschriftenartikelMaternal effects on offspring growth indicate post-weaning juvenile dependence in chimpanzees (Pan troglodytes verus) Samuni, Liran; Tkaczynski, Patrick; Deschner, Tobias; Löhrrich, Therese; Wittig, Roman M.; Crockford, CatherineBackground In animals with altricial offspring, most growth occurs after birth and may be optimized by post-natal maternal care. Maternal effects on growth may be influenced by individual characteristics of the mothers, ...

2019-10-07ZeitschriftenartikelMetabarcoding of eukaryotic parasite communities describes diverse parasite assemblages spanning the primate phylogeny Gogarten, Jan F.; Calvignac-Spencer, Sébastien; Nunn, Charles L.; Ulrich, Marcus; Saiepour, Nasrin; Vedel Nielsen, Henrik; Deschner, Tobias; Fichtel, Claudia; Kappeler, Peter M.; Knauf, Sascha; Müller-Klein, Nadine; Ostner, Julia; Robbins, Martha M.; Sangmaneedet, Somboon; Schülke, Oliver; Surbeck, Martin; Wittig, Roman M.; Sliwa, Alexander; Strube, Christina; Leendertz, Fabian H.; Roos, Christian; Noll, AngelaDespite their ubiquity, in most cases little is known about the impact of eukaryotic parasites on their mammalian hosts. Comparative approaches provide a powerful method to investigate the impact of parasites on host ecology ...

2022-03-22ZeitschriftenartikelQuantifying within-group variation in sociality—covariation among metrics and patterns across primate groups and species Schülke, Oliver; Anzà, Simone; Crockford, Catherine; De Moor, Delphine; Deschner, Tobias; Fichtel, Claudia; Gogarten, Jan F.; Kappeler, Peter M.; Manin, Virgile; Müller‑Klein, Nadine; Prox, Lea; Sadoughi, Baptiste; Touitou, Sonia; Wittig, Roman M.; Ostner, JuliaIt has long been recognized that the patterning of social interactions within a group can give rise to a social structure that holds very different places for different individuals. Such within-group variation in sociality ...

2018-01-18ZeitschriftenartikelSeasonal and inter-annual variation of malaria parasite detection in wild chimpanzees Wu, Doris F.; Löhrich, Therese; Sachse, Andreas; Mundry, Roger; Wittig, Roman M.; Calvignac-Spencer, Sébastien; Deschner, Tobias; Leendertz, Fabian H.Background: Cross-sectional surveys of chimpanzee (Pan troglodytes) communities across sub-Saharan Africa show large geographical variation in malaria parasite (Plasmodium spp.) prevalence. The drivers leading to this ...
