Nesting Implications for the Northern Gulf Loggerhead
July 31, 2014 10:29 AM - Allison Winter, ENN
After the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, a massive response to protect beaches, wetlands, and wildlife occurred. Nonetheless, because of the spill, extensive damage to marine and wildlife habitats were reported and many studies have been conducted to quantify the affects of the oil spill on specific species. One study in particular which started in the wake of the spill looks at the nesting of loggerhead sea turtles in the northern Gulf and how their feeding areas have been not only affected by the Deepwater Horizon spill, but by commercial fishing operations, and areas used for oil and gas extraction.
Boat noise impacts development and survival of marine invertebrates
July 31, 2014 08:42 AM - University of Bristol
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study by researchers from the UK and France. While previous studies have shown that marine noise can affect animal movement and communication, with unknown ecological consequences, scientists from the Universities of Bristol and Exeter and the École Pratique des Hautes Études (EPHE) CRIOBE in France have demonstrated that boat noise stops embryonic development and increases larval mortality in sea hares.
CO2 decrease cause of Antarctic ice sheet growth in ice age
July 31, 2014 06:15 AM - University of New Hampshire via ScienceDaily
Climate modelers from the University of New Hampshire have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide (CO2) levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global CO2 levels. In a paper published today in Nature, Matthew Huber of the UNH Institute for the Study of Earth, Oceans, and Space and department of Earth sciences provides evidence that the long-held, prevailing theory known as "Southern Ocean gateway opening" is not the best explanation for the climate shift that occurred during the Eocene-Oligocene transition when Earth's polar regions were ice-free.
Green Turtle success story

More than 70 years after major turtle nesting beaches became protected on the remote UK overseas territory of Ascension Island researchers are now reporting a boom in population numbers. Scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s.
Turtle Talk: Exactly how do turtles communicate?
July 29, 2014 08:49 AM - Morgan Erickson-Davis, MONGABAY.COM
Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
How to encourage recycling and feed stray animals at the same time!
July 27, 2014 08:28 AM - Kevin Mathews, Care2
Istanbul, Turkey recently unveiled awesome new machines that help both the environment and needy animals. Each time a person recycles a plastic bottle in the designated receptacle, pet food is ejected into a bowl at the bottom so hungry stray animals have something to eat. So far, the machines have been a hit with residents. People who would normally toss bottles in a trash can might wait to carry the plastic a bit longer to dispose of it in the recycling bin now that they know they can assist animals. It’s a win-win scenario that doubles Turkish people's incentive to do the right thing.
New fossils suggest ALL dinosaurs had feathers
July 25, 2014 09:50 AM - University of Bristol
The first ever example of a plant-eating dinosaur with feathers and scales has been discovered in Russia. Previously only flesh-eating dinosaurs were known to have had feathers so this new find indicates that all dinosaurs could have been feathered. The new dinosaur, named Kulindadromeus zabaikalicus as it comes from a site called Kulinda on the banks of the Olov River in Siberia, is described in a paper published today in Science.
Moose Drool Detoxifies Fungus
July 25, 2014 06:06 AM - Allison Winter, ENN
Saliva contains important substances helps us digest food. It also plays a part in keeping our mouths clean and healthy. Another newly discovered use? Making toxic plants less toxic. Not for us of course, but according to new research, moose and reindeer saliva can help can slow the growth of a toxic grass fungus, and subsequently make it less toxic for them, allowing the animals to graze on the grass without negative effects.
Why Seals Might Love Having More Wind Farms
July 24, 2014 12:27 PM - Steve Williams, Care2
New research reveals that off-shore wind farms are particularly useful for seals as they appear to act like artificial reefs, drawing in large groups of fish. The study, carried out by researchers at St Andrews University in Scotland and published this month in the journal Current Biology, saw scientists track a group of seals in the North Sea using GPS devices. The purpose of the study was to look at whether man-made changes to the structural ocean environment are affecting marine predator behavior.
Save the Bluefin Tuna
July 24, 2014 08:23 AM - Center for Biological Diversity
The National Marine Fisheries Service opened a public process today to determine whether to prohibit fishing for Pacific bluefin tuna, which have suffered a 96 percent decline since large-scale fishing began. The action followed the Center for Biological Diversity’s rulemaking petition sent in April. The Pacific bluefin population’s historic low triggered a requirement for new regulations to better manage overfishing by April 8, 2014, but regulators thus far have declined to take any steps to help the fish. Today’s request for comments is the federal government’s first step to spur action from the Pacific Fishery Management Council.
