Comments Off on Tiny treadmills for turtle hatchlings help scientists evaluate their stamina

When baby sea turtles are born, within their first 24 hours they make the journey from nest to ocean . The trek which should take a few minutes sometimes lasts hours in urban settings where artificial light can disorient the hatchlings. Two Florida Atlantic University (FAU) scientists employed wee treadmills and little swimsuits to dig into the turtles’ swimming performance after crawling for so long – and they were surprised by what they found. Speed is crucial for turtle hatchlings, who face dangers on their way to the ocean. Their survival “depends heavily on their ability to swim,” according to FAU. But in urban settings, excess light from streets and buildings can draw the babies away from the ocean and towards land – where they might get run over by traffic, drown in a pool, or be eaten by a predator. Biological sciences associate professor Sarah Milton said in a statement, “What prompted our study was the desire to understand what happens to these hatchlings after they spend hours crawling on the beach because they are disoriented. We wanted to know if they would even be able to swim after crawling 500 meters or more, which could take them as long as seven hours to complete.” Related: Police Officer Saves Nearly 100 Baby Sea Turtles in Florida Milton and graduate student Karen Pankaew conducted what FAU described as the “first study on disorientation to examine the physiological effects of extended crawling and swimming performance.” They gathered 150 hatchlings from 27 loggerhead and 18 green turtle nests in Palm Beach County, Florida . The hatchlings walked on tiny treadmills before swimming in a tank in a specially designed swimsuit. The scientists measured oxygen consumption, lactate accumulation, and swimming breathing and stroke rates. Field studies supplemented laboratory observations. The hatchlings were placed into the ocean in their natural habitats shortly after collection. The study results completely surprised the researchers, according to Milton, who said, “We were expecting that the hatchlings would be really tired from the extended crawling and that they would not be able to swim well. It turned out not to be the case and that they are in fact crawling machines. They crawl and rest, crawl and rest and that’s why they weren’t too tired to swim.” She also said the study offers a scientific basis to back up lighting ordinances during hatching season. The Journal of Experimental Biology published the study in November. Via Florida Atlantic University Images via Pixabay and Jay Paredes

Hundreds of sea turtles found dead near El Salvador

Comments Off on Hundreds of sea turtles found dead near El Salvador

Why did hundreds of sea turtles perish near El Salvador ? The country’s ministry of environment and natural resources found 300-400 dead turtles in Jiquilisco Bay, so they took samples to try and determine why the animals died. National Geographic floated fishing and algal blooms as two reasons for the sea turtle die-offs. Around 300 to 400 sea turtles died near El Salvador, according to MARN . Locals began seeing the turtles the end of October; MARN announced the die-off on Twitter in early November. Several turtle species reside in the area, but so far it looks like ridleys have been the species most hit. The International Union for the Conservation of Nature classifies ridleys as vulnerable. Related: Unusually high number of humpback whale deaths prompts NOAA inquiry A red tide , or harmful algal bloom, led to turtle deaths in El Salvador in 2006 and 2013. Turtles can die after ingesting the blooms. But it’s not yet clear if a red tide caused these deaths. On November 3, MARN said they collected samples from seawater and the turtles’ tissues, and also took blood samples from a living turtle. The fishing industry has been to blame for turtle deaths in the past during shrimp trawling, as turtles can get caught in the nets. But a month-long moratorium began October 17, so the Eastern Pacific Hawksbill Initiative ‘s Mike Liles said fishing probably didn’t cause the 300 to 400 turtles to perish. Liles did say the practice is still dangerous for the creatures. This recent event is one of the biggest turtle die-offs El Salvador has experienced. Liles said large-scale die-offs could just get more common as industrial agriculture runoff worsens red tides. Conservation Ecology Lab ecologist Alexander Gaos agreed and said more conservation programs are needed. Via National Geographic Images via MARN El Salvador on Twitter ( 1 , 2 )

Is that a turtle in your pants or are you just happy to see me? Canadian Kai Xu just pleaded guilty to attempting to smuggle 51 turtles across the border by stuffing and taping the turtles down his pants. Officials saw Xu disappear behind a semi-trailer and when he reappeared, they saw, “irregularly shaped bulges under Xu’s sweatpants on both legs.” A second man was also charged in the smuggling attempt after being caught at a Detroit airport with over 200 turtles in his suitcase.

We all get into tight spots on occasion, and it’s at times when we’re particularly vulnerable that a helping hand from a friend is much appreciated. This giant Galapagos tortoise at a zoo in Taipei found himself in a bit of a pickle when he rolled over onto his back and couldn’t flip over on his own. Fortunately, his buddy was nearby and was able to help him out.

Comments Off on “Deafening” Sonic Cannons to be Used in New Oil Exploration Off U.S. East Coast

New offshore oil and gas exploration activities are set to start along the U.S. east coast after a three-decade hiatus, but a recent Bureau of Ocean Energy Management (BOEM) decision means that companies will be allowed to use sonic cannons as they map the ocean floor. BOEM acknowledges that whales, dolphins and turtles will be affected by the potentially deafening noise , with its own estimates stating 138,000 marine animals are at risk.

Green Sea Turtle photo from Shutterstock Green turtles are already endangered, and their lot seems to be getting worse. A new study conducted by the University of Queensland and published in the journal Conservation Biology shows that green turtles are significantly more likely to swallow plastic today than they were in the 1980s. The study found that the likelihood of a green turtle ingesting man-made trash jumped from about 30% to nearly 50% in 2012. It also confirmed that six of the world’s seven species of sea turtles have been found to ingest debris, and all six are listed as globally vulnerable and endangered .

Photo via Shutterstock It looks like Japan isn’t the only country to suddenly realize that its nuclear plants have radioactive water leaks . A report from Reuters says a nuclear plant in Taiwan may have been leaking irradiated water for three years. The news comes from a new report by the Taiwanese government watchdog called the Control Yuan, which found that the plant, located in the northern coastal area of Shihmen, has been leaking toxic water from storage pools of two reactors.

Comments Off on Study Shows the Antarctic Ozone Hole is Contributing to Global Warming

Climate scientists at Columbia University in New York have discovered that the hole in the Earth’s ozone layer may be contributing to global warming by altering wind patterns and cloud cover in the southern hemisphere. These meteorological changes appear to be affecting the way the sun’s radiation reflects off the clouds, leading to a warmer planet.
