Comparing Biodiversity Ecosystem Functions Restored

项目摘要

Objectives: 1. Measure spatial and temporal patterns of biodiversity in restored and pristine mangroves, using a combination of palynology, sediment DNA (sedDNA) and botany techniques. a. Detect changes in species composition over the past 5000 years using five-meter sediment cores at multiple mangrove sites. b. Compare biodiversity between pristine, present-day restored and pre-human impact mangrove forests. 2. Create ecological network models for each mangrove type, to determine important species and positive or negative species interactions, for ecosystem resilience and functional diversity, to improve restoration success.Hypothesis Biodiversity and ecosystem function will be lower in restored mangroves than pristine mangrove forests and will have reduced over time since pre-human impact timepoints. Methodology and Programme of Research The work will be split into four main sections: 1) sample collection in North Sulawesi, Indonesia; 2) palynology techniques, supervised by Prof. Ulrich Salzmann, Northumbria University; 3) DNA metabarcoding, carried out in the Northumbria NU-OMICS lab; and 4) ecological network analysis, supervised by Dr Darren Evans, Newcastle University.Research Applications Reconstructing ecological networks over the past 5000 years by applying a combination of traditional palynology and molecular ecology techniques, will enable us to determine a baseline of pre-human impact biodiversity composition and ecosystem function, in pristine and restored mangrove forests in North Sulawesi, Indonesia. It is hoped the results of the research will help to improve mangrove restoration efforts in Indonesia, by gaining new knowledge of important species and species interactions, informing decisions of species reintroductions and invasive species removal, and ultimately optimising ecosystem resilience and functional diversity.

目的:1。结合孢粉学、沉积物DNA （sedDNA）和植物学技术，测量恢复和原始红树林生物多样性的时空格局。a.利用多个红树林遗址的5米沉积物岩心检测过去5000年来物种组成的变化。b.比较原始的、现在恢复的和未受人类影响的红树林的生物多样性。2. 为每种红树林类型建立生态网络模型，以确定重要物种和积极或消极的物种相互作用，以提高生态系统的恢复能力和功能多样性，以提高恢复的成功率。恢复后的红树林的生物多样性和生态系统功能将低于原始红树林，并且自人类影响前的时间点以来将随着时间的推移而减少。研究方法和方案这项工作将分为四个主要部分：1)在印度尼西亚北苏拉威西岛收集样本；2)孢粉学技术，英国诺森比亚大学Ulrich Salzmann教授指导；3) DNA元条形码，在诺森比亚大学组学实验室进行；4)生态网络分析，由纽卡斯尔大学的达伦·埃文斯博士指导。通过结合传统孢粉学和分子生态学技术重建过去5000年的生态网络，将使我们能够确定印度尼西亚北苏拉威西原始和恢复的红树林中人类影响前的生物多样性组成和生态系统功能的基线。希望这项研究的结果将有助于改善印度尼西亚红树林的恢复工作，通过获得关于重要物种和物种相互作用的新知识，为物种重新引入和入侵物种清除的决策提供信息，并最终优化生态系统的恢复能力和功能多样性。
