| craniodental features in male mandrillus may signal size and fitness: an allometric approach. | according to a hypothesis in the broader mammalian literature, secondary sexual characteristics that have evolved to signal fitness and size to other conspecifics should exhibit positive allometry across adult males within a species. here this hypothesis is tested in the genus mandrillus. the overbuilding of bony features in larger individuals necessitates a functional explanation as bone is metabolically expensive to produce and maintain. canine size and size of the maxillary ridge are scaled a ... | 2012 | 22328467 |

| detection of hev-specific antibodies in four non-human primate species, including great apes, from different zoos in germany. | the hepatitis e virus (hev) has been described in humans and various animal species in different regions of the world. however, the knowledge on natural hev infection in non-human primates and the corresponding risk of zoonotic transmission is scarce. to determine whether primates in captivity are affected by hev infection, we investigated 259 individual sera of clinically healthy non-human primates of 14 species from nine german zoos. using a commercial double-antigen-sandwich elisa and a comme ... | 2018 | 29168441 |
| detection of hepatitis e virus antibodies among cercopithecidae and hominidae monkeys in cameroon. | we screened hepatitis e from 15 species of non-human primates. anti-hev igg was detected in 11.1% (1/9) mandrillus sphinx, 14.3% (2/14) gorilla gorilla, 5.9% (4/67) pan troglodytes and 8.7% (2/23) mandrillus leucophaeus, whereas anti-hev igm was detected in 1.5% (1/18) papio anubis, 28.6% (2/7) cercocebus agilis and 1.5% (1/67) pan troglodyte. | 2019 | 31179536 |
| comparative performance of orangutans (pongo spp.), gorillas (gorilla gorilla gorilla), and drills (mandrillus leucophaeus), in an ephemeral foraging task. | a goal of the comparative approach is to test a variety of species on the same task. here, we examined whether the factors that helped capuchin monkeys improve their performance in a dichotomous choice task would generalize to three other primate species: orangutans, gorillas, and drill monkeys. in this task, subjects have access to two options, each resulting in an identical food, but one (the ephemeral option) is only available if it is chosen first, whereas the other one (the permanent option ... | 2020 | 33135209 |
| genome sequences of novel members of previously described dna and rna virus families, isolated from feces of a drill monkey in nigeria. | the genomes of seven novel members of previously described dna and rna virus families are described here. these viruses were recovered using a viral metagenomic approach from the stool of a drill monkey (mandrillus leucophaeus) housed in a sanctuary in cross river state, nigeria. | 2020 | 32327518 |
| competition, seed dispersal and hunting: what drives germination and seedling survival in an afrotropical forest? | disentangling the contributions of different processes that influence plant recruitment, such as competition and seed dispersal, is important given the increased human-mediated changes in tropical forest ecosystems. previous studies have shown that seedling communities in an afrotropical rainforest in southeastern nigeria are strongly affected by the loss of important seed-dispersing primates, including cross river gorillas (gorilla gorilla diehli), chimpanzee (pan troglodytes elioti) and drill ... | 2019 | 31024680 |
