Ponds are important for aquatic biodiversity. However, currently, the vast majority are poorly managed, and hence heavily terrestrialised, with potentially negative implications for biodiversity. In partnership with AquaticEngineering this project explores the consequences of pond management, namely de-silting and de-shading, for biodiversity conservation. The merits of these techniques have not been previously tested and indeed have been questioned by some ecologists. This project seeks to combine contemporary limnological and biological investigation with palaeoecological analysis to provide vital information to guide good management practice and future agri-environment policy. The project will focus on three small 'marl pit' ponds in North Norfolk, eastern England, selected to fall along a gradient of terrestrialisation. Monitoring studies will be conducted at the two overgrown ponds prior to and after management. Additionally longer-term (decadal-centennial) responses to terrestrialisation will be assessed by palaeolimnological studies of these two sites. The proposed project will address the following key research questions: 1. How does terrestrialisation affect the chemical and ecological functioning of ponds? 2. How does pond management affect biological structure and species diversity? 3. Can pond management return lost biological communities? Cross-comparison of limnological data collected for the ponds, both before and after management, will permit an understanding of varying biological structure and ecological functioning under terrestrialised, non-terrestrialised and 'restored' open conditions, while the palaeolimnological studies will enable the nature and timescales of biological change due to terrestrialisation and de-shading to be examined, as well as determining the extent to which species lost during the terrestrialisation process are returned to the aquatic ecosystem. The student will spend time with our case partner AquaticEngineering thereby gaining a good knowledge of the requirements and aspirations of one of the country's leading aquatic consultancies with specialist expertise in pond and lake management. Equally, time spent with the CASE partner will facilitate communication of the project's findings to both the CASE partner and its many clients.

池塘对于水生生物多样性很重要。但是，目前，绝大多数人的管理不善，因此地面严重化，对生物多样性产生了潜在的负面影响。与AquaticEnginering合作，该项目探讨了池塘管理的后果，即脱落和去阴影，以保护生物多样性。这些技术的优点以前尚未经过测试，确实受到了一些生态学家的质疑。该项目旨在将当代的林理学和生物学研究与古生态分析相结合，以提供重要的信息，以指导良好的管理实践和未来的农业环境政策。该项目将集中在英格兰北诺福克市的三个小“泥泞的坑”池塘上，被选为沿着地面化的梯度降落。监测研究将在管理前后的两个杂草丛生的池塘进行。另外，将通过对这两个地点的古学研究来评估长期（十年中心）对陆地化的反应。拟议的项目将解决以下关键研究问题：1。陆地化如何影响池塘的化学和生态功能？ 2。池塘管理如何影响生物结构和物种多样性？ 3。池塘管理会返回失去的生物社区吗？在管理前后，在管理前后收集的池塘的羊水数据的交叉比较将允许在陆地化，非层次化和“恢复”开放条件下的不同生物结构结构和生态功能的理解，而古学研究将使造成的范围内的生物学变化在范围内造成的生物学变化，从而确定其在远处的生物学变化，并确定其范围内的范围，并确定了远处的生物学变化。陆地化过程将返回到水生生态系统。该学生将与我们的案件合作伙伴AquaticEngineering共度时光，从而对该国领先的水上咨询公司之一的要求和愿望有很好的了解，并在Pond和Lake Management方面具有专业知识。同样，与案件合作伙伴一起度过的时间将促进该项目的调查结果与案件合作伙伴及其许多客户之间的沟通。
