概括

休船影响港湾海豚的行为. 靠近,快速的船只会降低海豚的游泳速度,而远处的,快速的船只会增加它的游泳速度,影响它们浮出水面的间隔,并可能导致负面的人口影响.

科学领域:

海洋生物学海洋生物学
保护科学保护科学
行为生态学行为生态学

背景情况:

人类活动,特别是船只交通,对鱼有负面影响.
了解取决于环境的行为反应对于有效的海洋哺乳动物管理至关重要.
港湾海豚 (Phocoena phocoena) 是常见的沿海鱼,容易受到干扰.

研究的目的:

调查休船速度和距离对港湾海豚游泳速度和浮出水面间隔的影响.
为管理人类活动在关键海豚息地提供特定地点的数据.
评估船只干扰对港湾海豚的潜在个人和人口层面的影响.

主要方法:

利用两架无人机 (UAV) 在"海带"海域同时收集数据.
记录了海豚的游泳速度,浮出水面的间隔,以及最接近休船的距离.
采用了通用线性模型 (GLM) 分析来检查船特征和海豚行为之间的关系.

主要成果:

船速和距离之间的相互作用显著影响了海豚的游泳速度.
海豚在快艇附近降低速度,但在距离快艇更远的地方增加速度.
距离船只的距离减少导致海豚浮出水面间隔较短 (浮出水面更频繁).

结论:

娱乐船活动显然影响了港湾海豚的行为.
观察到的行为变化表明,对个体海豚和更广泛的人口可能会产生负面影响.
关于船只互动的特定地点数据对于制定针对港口海豚的有针对性的保护战略至关重要.

Buoyancy and Stability for Submerged and Floating Bodies

Buoyancy and Stability for Submerged and Floating Bodies

In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...
