| folivory as a constraint on social behaviour of langurs in south india. | folivory, being a dietary constraint, can affect the social time of colobines. in the present study, we compared food items and activity budgets of two closely related species of colobines inhabiting south india, i.e. the hanuman langur (semnopithecus hypoleucos) and nilgiri langur (semnopithecus johnii), to determine whether folivory had an impact on social time in these species. our study established that nilgiri langurs were more folivorous than hanuman langurs. nilgiri langurs spent much les ... | 2015 | 26431447 |
| demography and reproductive output in langurs of the western ghats, india. | life history traits evolve such that the reproductive output of an organism is maximized. demographic characteristics, a consequence of life history traits, indicate the reproductive output per individual in group-living species. both phylogenetic and ecological factors influence demographic traits. in the forests of the western ghats, india, we studied the demography of three langur species: semnopithecus johnii, a wet forest-dwelling species; semnopithecus hypoleucos, largely a wet forest-dwel ... | 2016 | 27328816 |
