概括
无人机 (UAV) 揭示了悬崖植物的多样性. 引入的山羊对沿海悬崖植物有负面影响,增加了外来物种,突出了排除食草动物为保护的需要.
科学领域:
- 植物学 植物学
- 生态生态学 生态生态学
- 保护生物学 保护生物学
背景情况:
- 悬崖植物群落的了解很少,并且由于无法访问,它们经常被排除在生物多样性评估之外.
- 无人驾驶飞行器 (UAV) 提供了一种新的解决方案,用于测量偏远和危险的环境,如悬崖.
研究的目的:
- 通过无人机远程摄影来评估沿海和内陆悬崖的植物变异性.
- 为了调查引入的悬崖山羊对韩国Gageodo的植物群落的影响.
主要方法:
- 在17个沿海和13个内陆悬崖上使用配备有远距离摄像头的无人机进行植物物种遥感.
- 比较了沿海和内陆悬崖之间的物种丰富性,组成和多样性,以及被放牧和未被放牧的地点.
主要成果:
- 无人机调查发现了154种在沿海和166种在内陆悬崖上的物种.
- 与沿海悬崖相比,内陆悬崖表现出更大的血管植物多样性,和木质物种的比例更高,草本物种较少.
- 与未被草地覆盖的悬崖相比,被草地覆盖的沿海悬崖显示出外来和单年草物种的比例增加.
结论:
- 沿海悬崖并非免受引入的食草动物对牧场的影响,即使在难以接近的微生态环境中也是如此.
- 应防止人类引入居住在悬崖上的食草动物,以保护本地悬崖植物群落.

02:16Light Acquisition
8.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
