Hence, females should choose mates displaying good health and an ability to resist para-site infections. Assuming a genetic basis for parasite resistance, partners with low parasite infections should be preferred over others in order to obtain resistance genes for their offspring (parasite-mediated sexual selection). With our interdisciplinary approach we will contribute to understanding both determinants of individual parasite infections and mechanisms of para-site-mediated sexual selection in primates. Specifically, we analyze faecal samples of free-ranging red-fronted lemurs (Eulemur fulvus rufus)to characterize their intestinal parasite fauna by means of the formalin-ethyl-acetate sedimentation technique. Parasite infections are being cor-related with (1) genetic correlates at the interleukin-4 locus, which is involved in parasite resistance, (2) proximate endocrine factors (testosterone and cortisol) that co-vary with the functioning of the immune system, and (3) socio-demographic data, such as sex, age and population group size of the hosts that may influence parasite infestations. Moreover, we examine whether primates use honest signals, such as conspicuous coloration, in order to assess their mate’s genetic quality. Using data from paternity analyses of the study population, we will be able to link parasite infection with reproductive success of males with different genetic and endocrine constitutions. As data collection was just about finished at the start of this conference, the presentation will give an overview of the project and present preliminary data."],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/13119"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.title","Parasite-mediated sexual selection in primates?

Grooming has been suggested to represent a service in a biological marketplace, exchanged either for grooming or for other social commodities or services. Accordingly, grooming is predicted to be approximately reciprocated within a dyad when no other services are being exchanged, but it should be more asymmetrical if partners have different quantities of other services to offer. We analysed 412 grooming bouts observed in four groups of free-ranging redfronted lemurs to test this prediction. Grooming in this species seems to take place in a highly reciprocal manner because partners usually alternate in the roles of groomer and gromee within a grooming bout. However, within dyads there were asymmetries in the duration of grooming given and received. In both sexes, more grooming was directed from low-ranking towards high-ranking individuals than vice versa, and in males this asymmetry became more pronounced as the number of subordinates per group increased. Grooming in bisexual dyads was generally skewed in favour of males, but patterns of grooming between the sexes were less clear than within the sexes. In addition, aggression occurred at high frequencies between classes of individuals that were characterized by nonreciprocal grooming, suggesting that grooming may serve as a means to reduce aggression in dyads with a high potential for conflicts. Taken together, our results indicate that a strict reciprocation of grooming can be offset by power differentials between partners, where grooming appears to be traded by subordinates in exchange for the tolerance of dominants."],["dc.identifier.doi","10.1016/j.anbehav.2008.08.032"],["dc.identifier.gro","3150787"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7578"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0003-3472"],["dc.title","Market effects offset the reciprocation of grooming in free-ranging redfronted lemurs, Eulemur fulvus rufus"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

Nonetheless, there is considerable agreement among EU citizens that the CAP still does not do enough to address ongoing environmental degradation and climate change (92% of nonfarmers, 64% of farmers) (1). In May and June 2018, the European Commission (EC) published the financial plan and legislative proposal for the CAP post-2020 (2), prompting numerous proposed amendments that the newly elected European Parliament (EP) will now have to consider. With an eye toward the next and final reform stages, including budget discussions and “trilogue” negotiations between the EC, the Council, and the EP to begin in autumn 2019, we examine whether the proposed post-2020 CAP can address key sustainability issues and meet societal demands for higher environmental performance."],["dc.identifier.doi","10.1126/science.aax3146"],["dc.identifier.pmid","31371602"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62377"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","1095-9203"],["dc.relation.issn","0036-8075"],["dc.relation.issn","1095-9203"],["dc.title","A greener path for the EU Common Agricultural Policy"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Although empirical studies supporting this link abound in various vertebrate orders, both the study of the dynamics and impact of parasite infections and infectious diseases in strepsirrhine primates have received little empirical attention. We conducted a longitudinal parasitological study on four groups of wild red-fronted lemurs (Eulemur fulvus rufus) at Kirindy Forest, Madagascar, during two field seasons in consecutive years to investigate i) the degree of gastrointestinal parasite infection on population and individual levels and ii) factors potentially determining individual infection risk. Using a comprehensive dataset with multiple individually assignable parasite samples as well as information on age, sex, group size, social rank, and endocrine status (fecal androgen and glucocorticoid), we examined parasite infection patterns and host traits that may affect individual infection risk. In addition, we examined whether parasite infection affects mating and reproductive success. Our results indicated high variability in parasite infection on individual and population levels. Time of year and group size was important determinants of variability in parasite infection. Variation in hormone levels was also associated with parasite species richness and parasite infection intensity. Differences in parasite infection between years indicate a potential immune-enhancing function of steroid hormones on nematode infections, which has not been reported before from other vertebrates studied under natural conditions. Male mating and reproductive success were not correlated to any measure of parasite infection, which suggests a nonfunctional role of the parasites we examined in primate sexual selection."],["dc.identifier.doi","10.1002/ajpa.21243"],["dc.identifier.gro","3150831"],["dc.identifier.pmid","20091843"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7624"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0002-9483"],["dc.title","Host intrinsic determinants and potential consequences of parasite infection in free-ranging red-fronted lemurs (Eulemur fulvus rufus)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
