Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater).They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. Nutrient loss from cultivated watersheds that are fertilized is much larger than from forests and grasslands. In agricultural areas, nutrient export varies with vegetation cover, nutrient management, and related agronomic practices, terrain, soil composition, rainfall, and flow paths (hydraulic connections to surface flow), and the extent of buffer vegetation (to take up or trap . An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems. 3 Abiotic characteristics. 4 Biotic characteristics. Autotrophic organisms. Aquatic fauna form an important component of upland ecosystems, however, Ramchunder et al. () is the only study which considers their response to drain blocking. Aquatic macro-invertebrate communities were sampled from streams Cited by:

AbstractPeatlands are found around the world and cover ∼% of the Earth’s surface. In the UK, peatlands cover % or ∼ Mha of the land surface and occur mainly in upland areas covering the headwaters of most major British rivers. However, large areas are now subject to prescribed vegetation burning despite policy guidance that recommends a strong presumption Cited by: A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric ds play a number of functions, including water purification, water storage, .   The chapter starts with a discussion of general patterns and processes (Sect. ), such as impacts of climate change on productivity, phenology and e impacts on specific ecosystem types, such as forests, grasslands and mires are discussed in more detail in subsequent sections (Sects. – ).The chapter concludes by discussing Cited by: 1.   1. Introduction. Fire, either as a management tool or as wildfire, is a landscape-scale disturbance and a critical regulator of the ecological, hydrological and biogeochemical function of landscapes around the world [1–4].This is the case in UK upland landscapes that notably include large areas of by:
