Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.

You know that going green helps the environment and often your bank account, but it can also play a key role in reducing accidents. Green lifestyles are generally healthier ones, so don’t forget about that bonus perk when you go eco-friendly. Whether it’s reducing the amount of chemicals in your home, reducing the pesticides in your food, or avoiding the need for a DWI attorney because you never drive (especially not under the influence), here are a few ways eco-friendliness equates to fewer accidents: 

1. No chance of a car crash

Statistically, taking public transportation such as a bus or train, or walking or cycling, is much less dangerous than taking a car. Distracted driving is on the rise; just take a look at the official government (UK) Distraction.gov site for statistics on accidents caused from phones, radios, food and sleepiness. A greener approach to getting around is simply less prone to accidents than taking a car.
 

Scientists studying the distribution of four commercial and recreational fish stocks in Northeast U.S. waters have found that climate change can have major impacts on the distribution of fish, but the effects of fishing can be just as important and occur on a more immediate time scale. The four species studied– black sea bass, scup, summer flounder, and southern New England/Mid-Atlantic Bight winter flounder – have varied in abundance and have experienced heavy fishing pressure at times over the past 40 years. 

Ever wonder what's in the black cloud that emits from some semi trucks that you pass on the freeway? Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Thomas Kirchstetter knows very precisely what's in there, having conducted detailed measurements of thousands of heavy-duty trucks over months at a time at two San Francisco Bay Area locations.

With a specially outfitted research van equipped with sophisticated monitors for several pollutant types, he and his team are studying emissions levels from diesel trucks to understand and analyze the impact of new control technologies and California air pollution regulations.

Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains. This results in survival in aquatic habitats where prey animals are rare, and in increased fitness if the animals and algae are caught in a well-balanced diet. An Austrian research group around Marianne Koller-Peroutka and Wolfram Adlassnig published these results in the respected journal Annals of Botany.
