概括

海洋地震调查显著降低了白和平头鱼的商业捕捞率,分别降低了99%和75%. 对白的影响持续至少10个月,这表明对渔业的潜在长期影响.

科学领域:

海洋生物学海洋生物学
渔业科学渔业科学
声学生态学声学生态学

背景情况:

地震调查会产生高强度的噪音,可能会损害海洋生物和改变行为.
东部白和平头虎的商业渔场与澳大利亚东南部的海洋地震调查 (MSS) 区域重叠.

研究的目的:

评估海洋地震调查对白和平头的商业捕捞率的影响.
量化这些对目标鱼类影响的持续时间.

主要方法:

丹麦商业捕网船在地震采集和控制区域 (11,000平方公里) 进行了分层的随机调查.
对商业日志数据进行了前后控制影响 (M-BACI) 分析.
捕捞率在地震和控制区域之间进行了比较,并随着时间的推移进行了分析.

主要成果:

与控制区域相比,在MSS实施后,白的捕捞率下降了99%,而平头的捕捞率下降了75%.
对白的负面影响持续至少在调查后10个月.
M-BACI分析证实白捕捞率有显著下降,但不是平头,可能是由于船队动态.

结论:

海洋地震调查可以对商业渔业产生重大影响,影响因物种而异,调查重叠.
鱼类很可能避免了地震收购区域或被迁移,而不是直接死亡.
需要进一步的研究,以了解物种特异性反应和渔业数据中的潜在掩盖效应.

Decreased pulse rate

Decreased pulse rate

Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Decreasing Function

Decreasing Function

A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2 in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

Osmoregulation in Fishes

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Light Acquisition

Light Acquisition

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.

Decreased Body Temperature

Decreased Body Temperature

A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...
