They are increasingly recognized for the important services that they provide to both the environment and human society such as wildlife and fish production, nutrient filtering, and carbon sequestration. A combination of low oxygen levels and dense plant canopies present particular challenges for organisms living in this aquatic habitat. This concise textbook discusses the universal environmental and biological feat. -- ISBN : 0191623776 (online ; pdf). -- 9780191623776. -- 9780199608942. -- 0199608946. -- 9780199608959. -- 0199608954. -- 0198525397. -- 0198525400. -- 9780198525394. -- 9780198525400. -- (YBP)7432945. -- 9786613623867.
