Researchers warn Solomon Islands logging threatens reef fishing stocks
A new report from the Nature Conservancy reveals that if logging in the Solomon Islands continues at its current rate, nearby reef fisheries will disappear within a decade. Important nursery areas for many reef fish are located right near highly forested islands. In areas where logging has occurred in the last ten years, there appear to be no juvenile reef fish species. The problem is with the silt from logging, which settles on corals and quickly kills them. The report notes that not all logging is bad, but improvements need to be made for logging operations and there are some areas that should be left alone.
‘Screams’ could chase away other marine life
A research project by scientists from the University of Western Australia are reproducing the “screams” of orcas to be played underwater in an attempt to scare away great white, tiger, and hammerhead sharks. The project is a part of a $16 million shark hazard mitigation program. However, marine biologist and shark conservationists Brad Norman says the project could end up chasing away other marine life, interrupting entire ecosystems. He also questions the effectiveness of using whale “screams” and is calling for a halt on the project. Why are sharks afraid of killer whales? Check out this crazy story from December 2011 about a group of killer whales attacking sharks.
Which Is It? Hurricane, Typhoon Or Tropical Cyclone?
The devastating images of the aftermath of Super Typhoon Haiyan have many people asking, what’s the difference between a typhoon and a hurricane? Nothing but location. As a group, hurricanes, typhoons and cyclones can be referred to as tropical cyclones because they are all rotating storms that spawn in the tropics. The storm gets labeled as a hurricane in the Atlantic, Caribbean, and central and northeast Pacific. It gets called a typhoon in the northwest Pacific. In the Bay of Bengal and the Arabian Sea, it is called a cyclone. Click here to learn more.
