Comprising various filamentous green macroalgae genera (including Cladophora, Ulva, Hydrodictyon and Spirogyra), blanket weed blooms can damage ecosystem services, conservation and amenity value of freshwaters. The algal masses can harbour pathogens, disrupt the ecological balance of ecosystems and reduce access for water-based activities. Reasons for the sudden proliferation of blanket weeds are poorly understood, but probably linked to nutrient (N and P) supply, climate warming, inter-species competition, and trophic interactions. The studentship will focus on understanding the extent of the problem in the UK, the causes of blanket weed blooms, and identifying sustainable management techniques. Support from the National Trust will include access to affected sites and relevant datasets, with a focus on Clumber Park Lake (Nottinghamshire) as a case study site.

地膜杂草由多种丝状绿色大型藻类（包括Cladophora， Ulva， Hydrodictyon和Spirogyra）组成，会破坏生态系统服务，保护和美化淡水的价值。藻类群可以藏匿病原体，破坏生态系统的生态平衡，减少水基活动的机会。地盖杂草突然繁殖的原因尚不清楚，但可能与养分（N和P）供应、气候变暖、物种间竞争和营养相互作用有关。该奖学金将侧重于了解英国问题的严重程度、地毯式杂草泛滥的原因，以及确定可持续的管理技术。国民信托的支持将包括访问受影响的地点和相关数据集，重点是克林伯公园湖（诺丁汉郡）作为案例研究地点。
