| phylogeny of the lemuridae revisited: evidence from communication signals. | phylogenetic relationships among the extant lemurid prosimians were assessed cladistically using stereotyped vocal, olfactory, and visual communication characters. among our results are 3 findings of particular importance. first, our data are consistent with those from several recent studies of highly repeated dna fragments in supporting a close phyletic affinity between lemur catta and the genus hapalemur. moreover, our results indicate that l. catta is nested within the hapalemur clade as the ... | 1994 | 7813970 |
| comparison of conservation metrics in a case study of lemurs. | conservation planning is important to protect species from going extinct now that natural habitats are decreasing owing to human activity and climate change. however, there is considerable controversy in choosing appropriate metrics to weigh the value of species and geographic regions. for example, the added value of phylogenetic conservation-selection criteria remains disputed because high correlations between them and the nonphylogenetic criteria of species richness have been reported. we eval ... | 2016 | 27113083 |
| cytogenetic study of hapalemur aureus. | the karyotype of hapalemur aureus was compared with those of other hapalemur species, allowing us to determine the phylogenetic position of this species on the evolutionary tree of the lemuridae. | 1991 | 1951662 |
| quantitative variability of cyanogenesis in cathariostachys madagascariensis-the main food plant of bamboo lemurs in southeastern madagascar. | giant bamboo (cathariostachys madagascariensis) is a major food plant for three sympatric species of bamboo-eating lemurs (hapalemur aureus, h. griseus, and prolemur simus) in the rain forests of southeastern madagascar. this plant species is strongly cyanogenic. however, quantitative data on cyanide concentration in c. madagascariensis are scarce. previous studies reported 15 mg cyanide per 100 g fresh shoot material (corresponding to approx. 57 micromol cyanide per gram dry weight). however, w ... | 2009 | 19132732 |
| consumption of cyanogenic bamboo by a newly discovered species of bamboo lemur. | three species of bamboo-eating lemurs were found to be sympatric in the southeastern rain forests of madagascar. sympatric species generally differ in habitat utilization or diet, but these three closely related bamboo lemurs lived in the same habitat and all ate bamboo. behavioral observation revealed that they did select different parts of the bamboo, and chemical analyses confirmed that there was a difference in the secondary compound content present in those selections. the growing tips of c ... | 1989 | 31964012 |
