Global biodiversity is becoming more threatened as the human population continues to grow and use the world’s resources. Turtles have the misfortune of being on the leading edge of biodiversity decline and serve as an indicator of ecosystem degradation.
Researchers have identified 16 turtle “hotspots” around the world. These regions host the many native species of tortoises and freshwater turtles. By focusing on such areas, conservationists can target preservation efforts where the greatest effects can be achieved.
Scientists from the Chelonian Research Foundation, Conservation International, and State University of New York at Stony Brook recently published an article in the journal Chelonian Conservation and Biology that names three types of hotspots—biodiversity hotspots, high-biodiversity wilderness areas, and turtle priority areas. Taxon richness and endemism values are offered for the 16 identified hotspots, which host 262 species, or 83 percent of all turtle species.
Oregon State University researchers have patented a new strain of a succulent red marine algae called dulse that grows extraordinarily quickly, is packed full of protein and has an unusual trait when it is cooked.
This seaweed tastes like bacon.
If it seems like you're pulling more bass than trout out of Ontario's lakes this summer, you probably are.
Blame it on the ripple effect of climate change and warming temperatures. Birds migrate earlier, flowers bloom faster, and fish move to newly warmed waters putting local species at risk.
To mitigate the trend and support conservation efforts, scientists at the University of Toronto (U of T) are sharing a way to predict which plants or animals may be vulnerable to the arrival of a new species.
A collection of fossilized owl pellets in Utah suggests that when the Earth went through a period of rapid warming about 13,000 years ago, the small mammal community was stable and resilient, even as individual species changed along with the habitat and landscape. By contrast, human-caused changes to the environment since the late 1800s have caused an enormous drop in biomass and “energy flow” in this same community, researchers reported today in Proceedings of the National Academy of Sciences.
According to a new study published in Nature Geoscience, the Greenland ice sheet has been shown to accelerate in response to surface rainfall and melt associated with late-summer and autumnal cyclonic weather events.
Samuel Doyle and an international team of colleagues led from Aberystwyth University's Centre for Glaciology combined records of ice motion, water pressure at the ice sheet bed, and river discharge with surface meteorology across the western margin of the Greenland ice sheet and captured the wide-scale effects of an unusual week of warm, wet weather in late August and early September, 2011.
Global air travel contributes around 3.5 percent of the greenhouse forcing driving anthropogenic climate change, according to the International Panel on Climate Change (IPCC). But what impact does a warming planet have on air travel and how might that, in turn, affect the rate of warming itself? A new study by researchers at the Woods Hole Oceanographic Institution and University of Wisconsin Madison found a connection between climate and airline flight times, suggesting a feedback loop could exist between the carbon emissions of airplanes and our changing climate. The study was published today in Nature Climate Change.
"Extreme." "Unprecedented." "Historic." Those are just a few of the words being used to describe the start of this year's fire season in North America. The wildfires are centered in the northwest of the continent, but their consequences are far-reaching. Thick smoke has blanketed parts of Wisconsin and North Dakota. It's triggered air alerts in Minnesota and Montana and muddied skies as far south as Tennessee and Colorado.
The amount of heat flowing toward the base of the West Antarctic ice sheet from geothermal sources deep within Earth is surprisingly high, according to a new study led by UC Santa Cruz researchers. The results, published July 10 in Science Advances, provide important data for researchers trying to predict the fate of the ice sheet, which has experienced rapid melting over the past decade.
Lead author Andrew Fisher, professor of Earth and planetary sciences at UC Santa Cruz, emphasized that the geothermal heating reported in this study does not explain the alarming loss of ice from West Antarctica that has been documented by other researchers. "The ice sheet developed and evolved with the geothermal heat flux coming up from below--it's part of the system. But this could help explain why the ice sheet is so unstable. When you add the effects of global warming, things can start to change quickly," he said.
Microbes, primarily bacteria and fungi, get a bad rap in today’s society. However they’ve long played an incredible role within the Earth’s ecosystem. And one of the most important places microbes are transforming the earth is in the Gulf of Mexico, where a number of strains are busy munching up the oil still left over from the Deepwater Horizon oil spill disaster.
The Deepwater Horizon oil spill, which took place just over five years ago caused a massive ecological disaster in and around the Gulf of Mexico. This is partially because the spill took so long to quell, with oil companies scrambling (and often failing) to stem the flow of oil from the seabed.
Rural Tulare County, Calif., is now being called the epicenter of this drought.
That's because at least 1,300 residential wells have run dry, affecting at least 7,000 people. When your taps start spitting out air here, Paul Boyer and his team are who you call.
Under a punishing midafternoon sun, Boyer helps muscle down five of these hefty 400-pound water tanks from a semi-truck flatbed. He helps run a local nonprofit that's in charge of distributing these 2,500-gallon water tanks to drought victims.
