WebStream water often diverges from the main channel into sediments below the stream surface, gravel bars next to the stream, or organic debris dams in the middle of the stream. These geomorphic structures have the potential to support processes that produce or consume inorganic N (NH4 , NO3−) and thus affect streamwater quality. We measured … WebStream ecologists have recently recognized that sediments below streams play an important role in lotic ecosystems. Water flows not only across the surface of stream channels, but also through sediment interstices; consequently, surface and subsurface biogeochemical processes are linked. Recent attempts to understand the influence of …

Aquatic ecosystems in semiarid regions: implications for resource management. Web6 mei 2024 · Among animals, ruminants are key contributors to climate change. This is because their burps contain a huge amount of methane. In fact, cattle are among the leading cause of agricultural greenhouse gas emissions. A single cow can produce ~150-500 g of methane/day, depending on the breed.
