项目摘要

Many countries are setting ambitious targets for habitat restoration and woodland expansion (e.g. Bonn Challenge), such as England's commitment to plant 11 million trees by 2022 and to restore 75% of protected sites to favourable condition (Defra2018). To ensure these efforts help to reduce biodiversity decline and restore ecosystem functioning in the face of increasing anthropogenic pressures such as climate change, they need to be strategic.In this project, the student will examine changes in invertebrate communities resulting from woodland creation utilising new and existing data collected under the WrEN project experimental platform. Specifically, we will address the followingquestions:1. What is the relative importance of local (e.g. patch size, age since establishment)vs. landscape-scale (e.g. amount and configuration of surrounding habitat)attributes in the development of invertebrate communities in secondary woodlands?2. What are the key drivers of functional diversity in woodland invertebratecommunities?3. How predictable is the trajectory of invertebrate community development as woodlands mature, i.e. are communities in secondary woodlands simply subsets of those found at older sites, or could they be considered novel assemblages?4. How do species functional characteristics, including dispersal and habitat specificity, act to limit colonisation, and what impact does this have on long term functional diversity and trophic complexity?

许多国家正在制定雄心勃勃的栖息地恢复和林地扩张目标（如波恩挑战），例如英国承诺到2022年种植1100万棵树，并将75%的受保护地点恢复到有利状态（Defra2018）。为了确保这些努力有助于减少生物多样性下降，并在气候变化等日益增加的人为压力下恢复生态系统功能，它们需要具有战略意义。在这个项目中，学生将利用在WrEN项目实验平台下收集的新数据和现有数据，研究林地创造导致的无脊椎动物群落的变化。具体而言，我们将解决以下问题：1。本地的相对重要性是什么（例如，补丁大小，建立以来的年龄）？次生林地无脊椎动物群落发展的景观尺度属性（如周围生境的数量和配置）林地无脊椎动物群落功能多样性的主要驱动因素是什么？随着林地的成熟，无脊椎动物群落的发展轨迹有多可预测？也就是说，次生林地中的群落只是在较老地点发现的群落的子集，还是它们可以被视为新的组合？物种的功能特征，包括扩散和栖息地特异性，是如何限制定殖的？这对长期的功能多样性和营养复杂性有什么影响？
