South East Asia is currently undergoing an extinction crisis due to intensifying environmental and anthropogenic pressures. Specifically, large mammals face multiple threats due to habitat loss, climate change, unsustainable hunting and illegal poaching. For example, the Malayan sun bear (Helarctos malanayus) is losing habitat across its range due to unprecedented rates of deforestation, but it is also at threat from hunting for body parts and persecution as agricultural pests. These pressures result in defaunation or 'empty-forest syndrome' in some of the world's most biodiverse regions. To address this urgent issue, Katie's research will aim to determine the relative influence of environmental change and persecution on wildlife populations, predominately targeting flagship species such as the sun-bear and orang-utan in Indonesian Borneo (Kalimantan). She will take an interdisciplinary approach by combining the natural and social sciences to understand which species and which regions of Kalimantan are most at risk. Katie will combine an existing camera-trap dataset from eight forest sites across a disturbance gradient in Kalimantan with two new camera-trap surveys to determine environmental influences on large mammal occupancy. In 2020, she will re-sample one of the existing sites to investigate temporal change and, in 2021, implement a new camera survey in a previously unsampled region. Additionally, a questionnaire will be designed using innovative methods for asking sensitive questions, to investigate the prevalence of hunting and mammal exploitation in the area. Ultimately, this research project will combine ecological and social datasets to determine the combined and relative impacts of environmental change and persecution on threatened mammalian megafauna, helping inform wider conservation strategies in the region and target high-risk areas of defaunation.

由于环境和人为压力的加剧，东南亚目前正在经历一场灭绝危机。具体而言，由于栖息地丧失、气候变化、不可持续的狩猎和非法偷猎，大型哺乳动物面临多重威胁。例如，由于前所未有的森林砍伐率，马来太阳熊（Helarctos malanayus）正在失去其整个范围的栖息地，但它也受到狩猎身体部位和农业害虫迫害的威胁。这些压力在世界上一些生物多样性最丰富的地区造成了动物灭绝或“空林综合症”。为了解决这个紧迫的问题，凯蒂的研究将旨在确定环境变化和迫害对野生动物种群的相对影响，主要针对印度尼西亚婆罗洲（加里曼丹）的太阳熊和红毛猩猩等旗舰物种。她将采取跨学科的方法，结合自然科学和社会科学，以了解哪些物种和加里曼丹哪些地区最危险。凯蒂将联合收割机结合现有的相机陷阱数据集从八个森林网站在加里曼丹岛的干扰梯度与两个新的相机陷阱调查，以确定环境对大型哺乳动物的影响。2020年，她将对现有的一个地点进行重新采样，以调查时间变化，并于2021年在以前未采样的地区实施新的相机调查。此外，还将使用提出敏感问题的创新方法设计一份问卷，调查该地区狩猎和哺乳动物剥削的普遍程度。最终，该研究项目将结合联合收割机生态和社会数据集，以确定环境变化和迫害对受威胁的哺乳动物巨型动物的综合和相对影响，帮助为该地区更广泛的保护战略提供信息，并针对高风险的动物区。
