概括
有害藻类繁殖 (HABs) 显著影响旅游业经济. 经济损失与开花强度没有线性相关,这表明人为因素介于HAB对旅游收入的影响.
科学领域:
- 环境科学 环境科学
- 海洋生物学 海洋生物学
- 旅游经济学 旅游经济学
背景情况:
- 有害藻类繁殖 (HABs) 是一个全球现象,对旅游业有着显著的,但量化不良的经济影响.
- 佛罗里达州的沿海旅游经常受到海洋HAB的威胁,需要了解它们的经济后果.
研究的目的:
- 实证地评估佛罗里达州旅游业因HABs而造成的经济损失.
- 调查HAB强度,持续时间和旅游收入之间的关系.
主要方法:
- 利用一个月级和县级面板数据库,将旅游业务销售与佛罗里达州的HAB监控数据结合起来.
- 雇用时间和空间固定效应回归以量化旅游收入损失,每天红潮.
主要成果:

01:06Primary 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.

02:26Ecological Disturbance
17.1K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

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.
