Investigating components of prospective cognition in gibbons (<i>Hylobatidae</i>)
… within the small apes (<i>Hylobatidae</i>). Gibbons represent the only surviving divergence between large apes and monkeys. As such, assessment of basic prospection and component processes within gibbons allows for a clearer overview of the emergence of prospective abilities across the …

Infinite-Centre Gibbons-Hawking Metrics, Applied to Gravitational Instantons and Monopoles
We investigate the convergence of infinite-centre Gibbons-Hawking metrics, in the contexts of four-dimensional gravitational instantons and their applications, Kaluza-Klein monopoles and vortices, gravitational calorons, analytical extensions of Majumdar-Papapetrou metrics to form extreme …

Comparisons of Captive Gibbons’ (Hylobatidae) Intrapair Behaviors Indicative of the Pair Bond
I aimed to better understand captive gibbons’ pair bonds by studying behaviors that may indicate the relationship’s quality. I completed this research at The Gibbon Conservation Center (GCC) in Santa Clarita, California and observed four species: eastern hoolock (<em>Hoolock leuconedys</em>), Javan …

An Interdisciplinary Examination and Assessment of Current Conservation Initiatives for Javan Gibbons (Hylobates moloch)
… the long-term population viability of Javan gibbons with regards to current threats they face in the wild (habitat loss and the illegal pet trade); I investigated the illegal selling of gibbons through an extensive internet search on various social media platforms and compiled photographic …

Reproduction and growth of the Tule perch Hysterocarpus Traskii (Gibbons) with notes on its ecology
This study was initiated to obtain information about the natural history of the tule perch before greater reduction in population has occurred. The studies of Hopkirk (1962) and Turner (1966) did not include information on reproduction, development, and growth of embryos within the ovarian sac, and …

The Activity Budgets of Captive Javan Gibbons (<i>Hylobates moloch</i>) and their Response to Visitor Presence or Absence
… captive animals in zoos and sanctuaries. Javan gibbons (<em>Hylobates moloch</em>) are endangered, and healthy captive populations are important to the species’ conservation. The purpose of this study is to assess the impact of visitor presence on the activity budgets of captive Javan gibbons. …

Javan Gibbon (Hylobates moloch) Non-Vocal Social Communication and Gesture Use With Conspecifics
I explored gestures used by captive Javan gibbons (<em>Hylobates moloch</em>) at the Gibbon Conservation Center (Santa Clarita, CA). I hypothesized that a sender gibbon’s gesture modality would vary with the recipient gibbon’s attentional state and the sender would be equally likely to use all …

Effects of seed dispersal by gibbons, sambar, and muntjac on Choerospondias axillaris demography, and the disruption of this mutualism by wildlife poaching
… on the dispersal of its seeds to light gaps by gibbons (Hylobates lar), sambar deer (Cervus elaphus), and muntjac deer (Muntiacus muntjak). In parks where these mammals are heavily hunted, far fewer seeds are dispersed to light gaps and seedling abundance is significantly reduced. These results …

Enrichment Use & Social Interactions in a Mixed-Species Enclosure of Sumatran (Pongo abelij) & Bornean Orangutans (P. pygmaeus) & Northern White-Cheeked Gibbons (Nomascus leucogenys)
… sympatric with siamangs and agile and Bornean gibbons, so several zoos house these four Asian ape species in the same enclosure, in part, as social enrichment. In my study, I observed enrichment use and social interactions in a mixed-species enclosure at the Oregon Zoo, which housed two …

Acoustic Analysis of Nomascus Gibbon Songs as a Potential Measure of Current Health Status
… is vital to the rehabilitation process. Gibbons offer a unique challenge, as they are notoriously difficult to follow through the forest, but their duets offer a non-invasive window into their lives. The aim of this project is to create a method that will evaluate the health of …

Group density estimates for lar gibbons (Hylobates lar) and siamangs (Symphalangus syndactylus) and the quantitative analysis of the vegetative characteristics of the Sikundur field site.
… critical problems for arboreal animals, such as gibbons and siamangs. Gibbons and siamangs!are arboreal primates, dependent on closed continuous canopies for feeding and travelling. Apart from information from the Sabangau Catchment in central Kalimantan, there is very limited data available for …

The Ape Ecological Niche: Posture and Hand Use in Gibbons and Macaques and the Influence of Manual Skill on Cognitive Development in Apes and Humans

Family Dynamics in Eastern Hoolock (Hoolock leuconedys), Javan (Hylobates moloch), Pileated (H. pileatus) and Northern White-Cheeked Gibbons (Nomascus leucogenys) at the Gibbon Conservation Center
… white-cheeked (<em>Nomascus leucogenys</em>) gibbons housed at the Gibbon Conservation Center (GCC) in Santa Clarita, CA. I recorded all occurrences of approach, retreat, groom and play behaviors as well as the proximity individuals maintain between each other. I predicted: 1. offspring would …

Newtonian Twistor Theory
… the complex structure, exhibiting a jump to the Gibbons- Hawking class of twistor spaces. We show how Newton-Cartan connections can be constructed on the moduli space by means of a splitting procedure augmented by an additional vector bundle on the twistor space which emerges when considering the …
