| diet and feeding behaviour of the black-and-white ruffed lemur (varecia variegata variegata) in the betampona reserve, eastern madagascar. | the feeding behaviour and diet of the black-and-white ruffed lemur (varecia variegata variegata) was investigated in the betampona reserve, eastern madagascar. the highly frugivorous diet of this subspecies was confirmed - feeding on fruits accounting for 92.0% of feeding records. most feeding at betampona was observed at 10-25 m above the forest floor amongst flexible, small (0.5-5.0 cm diameter) and oblique/horizontal (0-45 degrees ) supports. the varecia spent on average 21.7% (+/- 1.5) of th ... | 2000 | 10828690 |
| captive breeding, reintroduction, and the conservation genetics of black and white ruffed lemurs, varecia variegata variegata. | a character-based phylogenetic species concept approach was used to examine conservation unit status for three wild populations of black and white ruffed lemurs, varecia vareigata variegata, from betampona (n = 3), manombo (n = 6), and ranomafana (n = 14), madagascar. population aggregation analysis was performed on 548 bp from the control region (d-loop) of the mitochondrial dna (mtdna). twenty-one diagnostic sites were found to differentiate the betampona (northern) population from the manombo ... | 1999 | 10703554 |
| reproductive activity of ruffed lemurs (varecia variegata variegata) in a madagascar rain forest. | mating activity was observed during four breeding seasons in two groups of black and white ruffed lemurs (varecia variegata variegata) living in lowland rain forest on nosy mangabe island, madagascar. the onset of the may-july breeding season was signalled by behavioral changes in adult males. males made forays outside their usual home ranges, were more aggressive to other males, and performed appetitive and other sex-specific behaviors more frequently. females showed receptive and proceptive be ... | 1993 | 8512055 |
