| wildlife reintroduction: considerations of habitat quality at the release site. | assessing the suitability of a habitat prior to the release of animals is vital. proper assessment of the flora will allow reintroduction programmes to determine whether the area will be capable of supporting the released animals in the long-term. here data are presented from an island in central kalimantan, indonesia which has been used as a release site for agile gibbons (hylobates agilis albibarbis) since january 2003. | 2006 | 16611369 |
| survey of hylobates agilis albibarbis in a logged peat-swamp forest: sabangau catchment, central kalimantan. | few data are available on gibbon populations in peat-swamp forest. in order to assess the importance of this habitat for gibbon conservation, a population of hylobates agilis albibarbis was surveyed in the sabangau peat-swamp forest, central kalimantan, indonesia. this is an area of about 5,500 km(2) of selectively logged peat-swamp forest, which was formally gazetted as a national park during 2005. the study was conducted during june and july 2004 using auditory sampling methods. five sample ar ... | 2006 | 16736263 |
| unusual behaviour of captive-raised gibbons: implications for welfare. | unusual behaviours not normally seen in the wild were studied in 52 captive agile (hylobates agilis albibarbis) and 23 müllers gibbons (h. muelleri spp) at three locations within the kalaweit gibbon rehabilitation project. unusual behaviours included stereotypic behaviour (sb), human-directed masturbation and posterior presenting. these data were collected over 18 months as part of an ongoing study into behavioural adaptation of gibbons in a rehabilitation programme. data were also collected on ... | 2006 | 16741606 |
| sexual swellings of female gibbons. | female gibbons were observed for labial swellings from march 2002 to august 2003. data were collected on length of time each female was swollen, changes in swelling period as females matured, and cycle length (number of days between onsets of consecutive swellings). data were also collected on the behaviour of the males when the females were swollen. there was a significant relationship between age of the female gibbon and number of days she had labial swelling. there was no significant relation ... | 2006 | 16912502 |
| population survey of bornean white-bearded gibbon, hylobates albibarbis,in two selective logging concessions in central kalimantan and west kalimantan. | we surveyed bornean white-bearded gibbon, hylobates albibarbis, population densities in lowland and hill dipterocarp forests within the sari bumi kusama and suka jaya makmur logging concessions. these surveys were conducted from 20 to 30 march 2018 in sari bumi kusuma areas and 14 to 24 april 2018 in suka jaya makmur. we used a fixed-point count method to detect and plot morning song bouts of gibbon groups at systematically placed listening posts. at each location in sari bumi kusuma and suka ja ... | 2020 | 31743920 |
