概括
日食显著影响蜜蜂的食行为. 在环状日食期间,蜜蜂活动,特别是蜜蜂和无刺蜜蜂的活动减少,在全食期间观察到的活动最小.
科学领域:
- 动物学 动物学
- 动物行为 动物行为
- 昆虫学 昆虫学是一门学科.
背景情况:
- 众所周知,日食会影响动物行为.
- 蜜蜂依靠太阳进行导航,视觉和食.
- 了解蜜蜂对日食的反应,可以了解昆虫对太阳线索的感觉依赖.
研究的目的:
- 为了研究日食对蜜蜂寻活动的影响.
- 为了确定哪些蜜蜂物种受到日食的影响最大.
- 为了确定日食影响蜜蜂行为的关键阶段.
主要方法:
- 在南印度的环状日食期间,对精选的蜂友好植物 (Cleome rutidosperma,Hygrophila schulli,Mimosa pudica,Urena sinuata) 进行蜜蜂食活动的观察.
- 在日食和非日食的日子记录访客丰富度和访问率.

01:50Threats to Biodiversity
22.2K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
