| the largest relative testis size among primates and aseasonal reproduction in a nocturnal lemur, mirza zaza. | testis size is an indirect indicator of a species' mating system, along with sexual size and canine dimorphism, existence and usage of mating and advertisement calls as well as the spatial distribution of males and females ready to mate in solitary species. upon its recent discovery, the northern giant mouse lemur mirza zaza was suggested to have a polygynandrous mating system and to exhibit seasonal breeding. we tested these predictions in a field study in sahamalaza national park, nw madagasca ... | 2015 | 26119092 |
| lemurs in cacao: presence and abundance within the shade plantations of northern madagascar. | the recognition that much biodiversity exists outside protected areas is driving research to understand how animals survive in anthropogenic landscapes. in madagascar, cacao (theobroma cacao) is grown under a mix of native and exotic shade trees, and this study sought to understand whether lemurs were present in these agroecosystems. between november 2016 and march 2017, discussions with farmers, nocturnal reconnaissance surveys and camera traps were used to confirm the presence of lemurs in the ... | 2020 | 31574526 |
| spacing and mate attraction: sex-specific function of advertisement calls in the northern giant mouse lemur (mirza zaza). | it has been proposed that primates use advertisement calls exclusively to negotiate spacing, but the function of female calls has rarely been studied. here, we investigated the function of male and female advertisement calls in the northern giant mouse lemur (mirza zaza),a non-gregarious nocturnal primate from north-western madagascar. we recorded advertisement calls and associated behaviours of 35 m. zaza individuals at the duke university lemur center. we found that females of m. zazaexclusive ... | 2019 | 31416068 |
