Crocodiles and Turtles of Borneo. Spiny Turtle (Heosemys spinosa) 22 cm Emys spinosa J. E. Gray. 1831. Syn. Rept.: 20. Heosemys spinosa Type: Untraced in The Natural History Museum, London, the repository of most of J. Identification: The young ones of this turtle resemble pin cushions, with greatly expanded marginals with distinct spines that disappear or become less obvious with growth, or through wear and tear. Natural history: The species inhabits forests, usually in the uplands, and may be found far from water. Distribution: This turtle ranges from southern Myanmar, through Thailand and Peninsular Malaysia and Singapore to the islands of Sumatra, Borneo and the Natunas.

Green sea turtles (Chelonia mydas) seem to really enjoy taking time out to get cleaned. These gold-ring surgeonfish (Ctenochaetus strigosus) and yellow tangs (Zebrasoma flavescens) eek out a living nibling at algae that grows on the reef. You can imagine their excitment when a turtle who's been out at sea arrives sporting a shell with a lush carpet of algal growth. This turtle has an injured flipper. Monofilament fishing line and other refuse create entanglement hazards for a wide variety of marine animals, turtles included. Green sea turtle (Chelonia mydas) and orangespine unicornfish (Naso lituratus). This green sea turtle (Chelonia mydas) appears to be giving me a one-flipper salute.

Living in a Landscape of Fear: How Predators Impact an Ecosystem: Scientific American. Editor's Note: The following is an excerpt from Cristina Eisenberg's book The Wolf’s Tooth. A doe burst out of the forest and tore across the meadow, two wolves in close pursuit.

This drama unfolded not twenty feet from where my young daughters and I knelt in our garden peacefully pulling weeds, our pant legs wet with morning dew. One black, the other gray, the black wolf in the lead, they closed in on the doe's haunches. In less than two heartbeats they pierced the deep wood on the far side of the meadow, leaving a wake of quaking vegetation. We live at the base of a mountain in northwestern Montana. As wild as the wildest places in the lower forty-eight United States, it isn't quite paradise, although the handful of us who live here think it comes close. Landscapes shape us and speak to us on a primal level.

Humans also have a primal relationship with large predators. I marked one track, and from it we located others laid out in a gallop pattern. "A tree," said some bright person. Edward Wilson. The classic article, published 2 decades ago by one of the world's great biologists & humanists Imagine that on an icy moon of Jupiter - say Ganymede - the space station of an alien civilization is concealed.

For millions of years its scientists have closely watched the earth. Because their law prevents settlement on a living planet, they have tracked the surface by means of satellites equipped with sophisticated sensors, mapping the spread of large assemblages of organisms, from forests, grasslands and tundras to coral reefs and the vast planktonic meadows of the sea. They have recorded millennial cycles in the climate, interrupted by the advance and retreat of glaciers and scattershot volcanic eruptions. The watchers have been waiting for what might be called the Moment.

When it comes, occupying only a few centuries and thus a mere tick in geological time, the forests shrink back to less than half their original cover. Darwin's dice have rolled badly for Earth. 'Virtual water' lecturer turns attention to Ogallala. How To Heat Up Your Room Using Just a Candle: Kandle Heeter! | Green Electronics. This heater is a multi-core steel and ceramic radiator assembly, suspended above the candle on a solid steel stand.

The radiator absorbs and concentrates the thermal energy of the candle and converts it into dry radiant space heat. If you burn candles, now you can add their heat to your home or office. There is also an “electric candle” option that uses a 60 watt quartz halogen lamp; that works out to about 6 cents for 10 hours of “burn” time. “Steel has the ability to approach the temperature of its heat source,” says the inventor, “so the solid steel inner core will go as high as 550° Fahrenheit. That high inner temperature is mitigated to a very warm 160° to 180° on the outer surface. As long as the candle remains under the steel the surface is constantly emitting dry radiant heat.” The simple elegant design has no moving parts. The electric candle is pictured below: The Kandle Heeter Candle Holder is available on Doyle Doss’s website, for $29.95. Oceanus : Fertilizing the Ocean with Iron. By Hugh Powell :: Originally published online : In print Vol. 46, No. 1, Jan. 2008 “Give me half a tanker of iron, and I’ll give you an ice age” may rank as the catchiest line ever uttered by a biogeochemist.

The man responsible was the late John Martin, former director of the Moss Landing Marine Laboratory, who discovered that sprinkling iron dust in the right ocean waters could trigger plankton blooms the size of a small city. In turn, the billions of cells produced might absorb enough heat-trapping carbon dioxide to cool the Earth’s warming atmosphere. Never mind that Martin was only half serious when he made the remark (in his “best Dr. Strangelove accent,” he later recalled) at an informal seminar at Woods Hole Oceanographic Institution (WHOI) in 1988. At the time, ice-core records suggested that during past glacial periods, natural iron fertilization had repeatedly drawn as much as 60 billion tons of carbon out of the atmosphere.

(click for full image) My son called me today to discuss an article he is writing on the subject of sustainability. After some discussion of the problems of fisheries, forest harvesting, and fresh water distribution, we came to the conclusion that sustainability might be best defined as: “Exploiting a system at a rate that is equal to or less than the time required for that system to replenish and heal itself”. I think this idea is closely related to Deming’s concept of systems optimization in which a system must be regarded as whole. No single component of the system can be over-taxed or maximized without causing the system as a whole to become sub-optimized and eventually, to collapse.

We then turned our attention to global warning, wondering if this phenomenon could also be explained in terms of sustainability. Or will the system collapse and shift to another state altogether? Researcher collaborates on important study of how ocean dead zones are shrinking habitat for blue marlins, other tropical billfish and tunas :: NOAA Fisheries. Blue marlins and many other billfish are high energy fish that need large amounts of dissolved oxygen. By comparing the movement of the blue marlins and the location of low-oxygen areas, the study shows that blue marlins venture deeper when dissolved oxygen levels are higher and remain in shallower surface waters when low dissolved oxygen areas encroach on their habitat from below, squeezing them into surface waters.

December 9, 2011 The science behind counting fish in the ocean to measure their abundance has never been simple. A new scientific paper authored by NOAA Fisheries biologist Eric Prince, Ph.D., and eight other scientists shows that expanding ocean dead zones – driven by climate change – have added a new wrinkle to that science. In the December 4 paper published in the scientific journal Nature Climate Change, these scientists sound an alarm that expanding ocean dead zones are shrinking the habitat for high value fish such as marlins in the tropical northeast Atlantic Ocean.

Remote Antarctic island is 'richer in biodiversity than the Galapagos' Antarctica's remote South Georgia Island boasts 90 percent of the world's fur seals, half of the world's elephant seals, is navigated by vast populations of blue whales, sperm whales and killer whales, and has beaches that can be packed shoulder-to-shoulder with nesting penguins. In total, it contains nearly 1,500 recorded species, many of which are found nowhere else on Earth.

It's difficult to believe that until recently, this biological treasure was believed to be nothing more than an "inhospitable lump of rock. " In fact, researchers now believe that South Georgia Island contains more species than anywhere else in the Southern Ocean, and may be the most biologically diverse remote island in the world — even more diverse than the storied Galapagos Islands, according to the Independent.

"It shows you don't have to be a tropical island or in a hot part of the world to support a lot of marine life. The types of marine life around the island vary immensely.
