For decades, Borneo's once extensive and pristine forests have been increasingly exposed to a suite of anthropogenic disturbance and deforestation processes as a result of selective and illegal logging, hunting, droughts, fires and the conversion to plantations, chiefly oil palm. Such disturbance is likely impacting the Sunda clouded leopard, Neofelis diardi, and other threatened, sympatric Bornean felids, yet few studies have attempted to address these issues. In this thesis, I used data from intensive camera trap surveys throughout Sabah, Malaysian Borneo and high-resolution GPS data from tagged Sunda clouded leopards to examine the influence of forest disturbance on the abundance, distribution, movements and population connectivity of Sunda clouded leopards and other sympatric felids on Borneo, and to provide some of the first data regarding the ecological interactions and patterns of coexistence among this felid assemblage. I showed that Sunda clouded leopard movement was facilitated by forest cover with high canopy closure, and highly resisted by oil palm plantations with low canopy closure. Models of population connectivity across Sabah identified a number of isolated populations of these felids, which may be particularly threatened with extinction. Analysis of camera trap detection data revealed that the Bornean felids exhibit evidence of resource segregation along the temporal, spatial and prey niche axes, and showed that Sunda clouded leopards, bay cats, Catopuma badia, and marbled cats, Pardofelis marmorata exhibited broad scale avoidance of disturbed habitats but varied in their selection of optimal foraging habitat at fine scales. Conversely, leopard cats, Prionailurus bengalensis, were associated with forest disturbance and likely benefit from such changes. I developed some of the first estimates of population density for Sunda clouded leopards and the first such data for marbled cats. The results are discussed in the context of the conservation of these felids on Borneo.

The ancient continent of Sahul, encompassing Australia, New Guinea and Tasmania, contains some of the earliest archaeological evidence for humans outside of Africa, dating back to at least 50 thousand years ago (kya). New Guinea was also one of the sites were humans developed agriculture in the last 10 thousand years. Despite the importance of this part of the world to the history of humanity outside Africa, little is known about the population history of the people living here. In this thesis I present population-genetic studies using whole-genome sequencing and genotype array datasets from more than 500 indigenous individuals from Australia and New Guinea, as well as initial work on large-scale sequencing of other, worldwide, human populations in the Human Genome Diversity Project panel. Other than recent admixture after European colonization of Australia, and Southeast Asian ad- mixture in the lowlands of New Guinea in the last few millennia, the populations of Sahul appear to have been genetically independent from the rest of the world since their divergence ∼50 kya. There is no evidence for South Asian gene flow to Australia, as previously suggested, and the highlands of Papua New Guinea (PNG) have remained unaffected by non-New Guinean gene flow until the present day. Despite Sahul being a single connected landmass until ∼8 kya, different groups across Australia are nearly equally related to Papuans, and vice versa, and the two appear to have separated genetically already ∼30 kya. In PNG, all highlanders strikingly appear to form a clade relative to lowlanders, and population structure seems to have been reshaped, with major population size increases, on the same timescale as the spread of agriculture. However, present- day genetic differentiation between groups is much stronger in PNG than in other parts of the world that have also transitioned to agriculture, demonstrating that such a lifestyle change does not necessarily lead to genetic homogenization. The results presented here provide detailed insights into the population history of Sahul, and sug- gests that its history can serve as an independent source of evidence for understanding human evolutionary trajectories, including the relationships between genetics, lifestyle, languages and culture.
