Primary Production

23.6K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Bioremediation

18.5K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

概括

生态社区可以存在于多个稳定的状态或长短的过渡阶段. 特性长度尺度 (CLS) 有助于区分这些状态并管理生态系统的变化,尽管连续和不连续的变化仍然难以区分.

科学领域:

  • 生态生态学 生态生态学
  • 环境科学 环境科学
  • 复杂的系统复杂的系统.

背景情况:

  • 人类活动越来越多地改变生态系统,推动人们对理解和管理生态变化的兴趣.
  • 解释生态系统状态的变化是很困难的,特别是在快速变化的环境中,基于平衡的理论可能不适用.

结论:

  • CLS的变化和时间序列数据可以为管理策略提供信息,以减轻相位变化和保护生态系统服务.
  • 由于缺乏独特的动态信号,区分连续和不连续的相位变化仍然是一个挑战.
