Abstract Comparative analyses of survival senescence by using life tables have identified generalizations including the observation that mammals senesce faster than similar‐sized birds. These been challenged because limitations life‐table approaches and growing appreciation is more an increasing probability death. Without tables, we examine rates in annual individual fitness 20 individual‐based data sets terrestrial vertebrates with contrasting histories body size. We find widespread wild...
Abstract Where individuals contest access to a resource, escalated physical fighting presents risk all involved. The requirement for mechanisms of conflict management has led the evolution variety decision rules and signals that act reduce frequency aggression during competitive encounters. We examined strategies in male mandrills ( Mandrillus sphinx ) living two semi‐free‐ranging groups Gabon. Adult are large (31 kg), with long canines, making costs potentially very high. found males formed...
Wildlife tourism is proliferating worldwide and has the potential to raise revenue for conservation as well public awareness of issues. However, concerns are growing about potentially negative influence such on wildlife involved. We investigate effects habituation, ecotourism research activities levels faecal glucocorticoid metabolites (FGCMs), a proxy physiological stress, in wild western lowland gorillas (Gorilla gorilla gorilla) Central African Republic. compare FGCMs three...
Abstract Threats to biodiversity are well documented. However, effectively conserve species and their habitats, we need know which conservation interventions do (or not) work. Evidence-based evaluates within a scientific framework. The Conservation Evidence project has summarized thousands of studies testing compiled these as synopses for various habitats taxa. In the present article, analyzed assessed in primate synopsis compared with other We found that despite intensive efforts study...
Abstract We present body mass (N = 419) and crown‐rump length (CRL, N 210) measurements from 38 male 49 female mandrills born into a semifree‐ranging colony in order to describe growth birth adulthood, investigate maternal influences upon growth. Adult are 3.4 times the mass, 1.3 CRL, of adult females. Body dimorphism arises combination sex differences period (females attain at 7 years, males 10 years) rate. Both sexes undergo subadult spurt this is much more dramatic (peak velocity 551...
Abstract Behavioural observations suggest that orang‐utans are semi‐solitary animals with females being philopatric and males roaming more widely in search of receptive partners, leading to the prediction closely related than at any given site. In contrast, our study presents evidence for male female philopatry orang‐utan. We examined patterns relatedness parentage a wild orang‐utan population Borneo using noninvasively collected DNA samples from observed defecate, microsatellite markers...
Primates are traditionally considered to be microsmatic, with decreased reliance on olfactory senses in comparison other sensory modalities such as vision. This is particularly the case for Old World monkeys and apes (catarrhines). However, various lines of evidence suggest that chemical communication may important these species, including presence a sternal scent-gland mandrill. We investigated volatile components mandrill odor using gas chromatography-mass spectrometry. identified total 97...
The major histocompatibility complex (MHC) is an extraordinarily diverse cluster of genes that play a key role in the immune system. MHC gene products are also found various body secretions, leading to suggestion genotypes linked unique individual odourtypes animals use assess suitability other individuals as potential mates or social partners. We investigated relationship between chemical odour profiles and genotype large, naturally reproducing population mandrills, using gas...
Biodiversity conservation is one of the grand challenges facing society. Many people interested in biodiversity have a background wildlife biology. However, diverse social, cultural, political, and historical factors that influence lives can be investigated fully only by incorporating social science methods, ideally within an interdisciplinary framework. Cultural hierarchies knowledge hegemony natural sciences create barrier to understandings. Here, we review three different projects...
Abstract Conservation funding is currently limited; cost‐effective conservation solutions are essential. We suggest that the thousands of field stations worldwide can play key roles at frontline biodiversity and have high intrinsic value. assessed stations’ return on investment explored impact COVID‐19. surveyed leaders across tropical regions host primate research; 157 in 56 countries responded. Respondents reported improved habitat quality reduced hunting rates over 80% lower operational...
Over the last decade, paternity analysis using molecular markers has revealed that observed mating systems do not necessarily correlate with reproductive and thus cannot provide reliable information about male success (RS). This is especially true for primate species a complex multimale-multifemale social organization, such as mandrills (Mandrillus sphinx). Using measurement of individual RS comprehensive data set comprising 193 offspring from 27 birth cohorts over 20-year period sampling,...
Studies of secondary sexual ornamentation and its maintenance by selection tend to focus on males; however, females may also possess showy ornaments. For example, female mandrills facial coloration that ranges from black bright pink. We used fortnightly photographs 52 semi-free-ranging aged above 3years over 19 months evaluate whether colour conveys information concerning competitive ability, reproductive quality, age or status. Colour was not related rank quality (body mass index, at first...
We investigated reproduction in a semi-free-ranging population of polygynous primate, the mandrill, relation to genetic relatedness and male characteristics, using neutral microsatellite major histocompatibility complex (MHC) genotyping. compared dissimilarity mother characteristics sire with all other potential sires present at conception each offspring (193 for genetics, 180 MHC). The probability that given sired increased as pedigree decreased, overall MHC increased. Reproductive success...
