Acoustic disturbance has different effects on different species of fish, according to a new study from the Universities of Exeter and Bristol which tested fish anti-predator behaviour.
Three-spined sticklebacks responded sooner to a flying seagull predator model when exposed to additional noise, whereas no effects were observed in European minnows.
Lead author Dr Irene Voellmy of Bristol’s School of Biological Sciences said: “Noise levels in many aquatic environments have increased substantially during the last few decades, often due to increased shipping traffic. Potential impacts of noise on aquatic ecosystems are therefore of growing concern.” (more…)
The Arctic is home to a growing number of whales and ships, and to populations of sub-Arctic whales that are expanding their territory into newly ice-free Arctic waters. (more…)
Pollution is an unfortunate by-product of our ever-changing society. Air, water and even noise pollution can take a toll on any person’s body, without their knowledge. Fortunately, there ARE ways to fight the effects of pollution in your body, in order to maintain a healthy lifestyle. There are also helpful tips to decrease the toxins that are invading your body, which could potentially cause harmful consequences later in life. Here’s what you need to know!
The Consequences of Pollution
Impure surroundings affect the lungs, heart, cardiovascular system, immune system, and organs when dangerous toxins are inhaled, consumed or absorbed by the skin or airways. Respiratory ailments, such as colds, flu, pneumonia, emphysema and bronchitis occur often because of these. The chances of contracting asthma and COPD or Chronic Obstructive Pulmonary Disease are also more likely. Tainted environments also contribute to allergies, headaches, migraines, and skin disorders such as eczema, acne, melanoma cancer and premature aging.(more…)
