The requirement to feed a rapidly increasingly human population whilst maintaining ecosystem services and reducing biodiversity losses has led to an urgent need to design more sustainable agricultural landscapes. This is particularly relevant in SE Asia where oil palm plantations are replacing hyper-diverse tropical rainforest. Current policies for the sustainable cultivation of oil palm (an important source of edible vegetable oil) require the retention of rainforest fragments within plantations. However, the assumption that these forest fragments can continue to support high biodiversity, maintain their viability, and regenerate over time has not previously been tested. Thus one of the primary criteria for sustainability is essentially untested, and forms the basis of this proposal.SE Asian rainforests are unique in being dominated by Dipterocarpaceae trees which reproduce irregularly (at intervals from 1 to many years) but synchronously in mass fruiting events. One of these unpredictable mass fruiting events has recently been initiated on Borneo, and provides a rare opportunity to study dipterocarp reproduction in rainforest fragments. Dipterocarp trees are a vital component of rainforest ecosystems in SE Asia, and hence any changes that affect dipterocarps are likely to have considerable knock-on impacts for rainforest biodiversity. Our recent data show an absence of dipterocarp seedlings in small forest fragments even when mature dipterocarps are present, raising a serious concern of reproductive failure of dipterocarps in fragments. The recently-initiated mass fruiting event provides us with an opportunity to explore potential mechanisms leading to reproductive failure and/or recruitment failure in forest remnants. The main objective of this project is to: (1) examine how forest fragmentation affects dipterocarp reproduction, (2) relate reproductive rates to biotic and abiotic changes arising from forest fragmentation (altered microclimates, habitat quality, predation), and (3) assess whether dipterocarp species are equally sensitive to impacts of forest fragmentation. The proposed work will provide the first investigation of the long-term viability of forest remnants in tropical agricultural landscapes. The project will address fundamental questions about reproduction in dipterocarp trees under altered abiotic and biotic conditions, as well as producing results of considerable practical value for policy makers. It will form the basis for new research in future focussed on understanding the impacts of habitat degradation and fragmentation on biodiversity, and contribute to scientific evidence to inform the debate on developing effective conservation and sustainability strategies.

在维持生态系统服务和减少生物多样性损失的同时，养活快速增长的人口的要求导致迫切需要设计更可持续的农业景观。这在东南亚尤其重要，油棕种植园正在取代高度多样化的热带雨林。油棕（可食用植物油的重要来源）可持续种植的现行政策要求在种植园内保留雨林碎片。然而，这些森林碎片可以继续支持高度生物多样性，保持其生存能力，并随着时间的推移而再生的假设以前没有得到验证。因此，可持续性的主要标准之一基本上是未经检验的，这是本建议的基础。东南亚热带雨林的独特之处在于以双龙心科树木为主，这些树木的繁殖不规则（间隔1年至多年），但在大量结果事件中是同步的。其中一个不可预测的大规模结果事件最近在婆罗洲开始，并提供了一个难得的机会来研究热带雨林碎片中的龙脑果繁殖。龙脑树是东南亚雨林生态系统的重要组成部分，因此任何影响龙脑树的变化都可能对雨林生物多样性产生相当大的连锁影响。我们最近的数据显示，即使有成熟的龙脑树，在小的森林碎片中也没有龙脑树的幼苗，这引起了人们对龙脑树在碎片中繁殖失败的严重关注。最近开始的大规模结果事件为我们提供了一个探索导致森林残留物繁殖失败和/或招募失败的潜在机制的机会。该项目的主要目标是：(1)研究森林破碎化如何影响龙脑果的繁殖；(2)将繁殖率与森林破碎化引起的生物和非生物变化（小气候、栖息地质量、捕食）联系起来；(3)评估龙脑果物种是否对森林破碎化的影响同样敏感。拟议的工作将首次对热带农业景观中森林遗迹的长期生存能力进行调查。该项目将解决关于在改变的非生物和生物条件下龙脑树繁殖的基本问题，并为决策者产生具有相当实际价值的结果。它将为今后着重了解生境退化和破碎化对生物多样性的影响的新研究奠定基础，并为制定有效的保护和可持续性战略的辩论提供科学证据。
