Driving through Vail, Colorado, the colors of the landscape are impossible to ignore. Glancing out of a car window you cant help but notice the crystal clear water, blue skies, green vegetation and… rusty red trees?With nearly 80 percent of the lodge pole pine trees in the Vail Valley expected to die within the next [...]

Therefore, established colonies of M. truncata seem well able to withstand the levels of ocean acidification predicted in the next 200 years, possibly because the soft tissues protect the skeleton from an external decrease in pH. However, during the second period of observation a prolonged period of high seawater temperatures (25–28 °C) halted calcification both [...]

An entertaining science writer comes up with this list: 1) Woolly mammoth 2) Dodo 3) Sabre Toothed Tiger 4) Thylacine (Marsupial Tiger) 5) Glyptodon 6) Irish Elk 7) Short faced bear Neaderthal 9) Giant sloth 10) Woolly rhino 11) Moa To these I would add: 1) Procoptodon goliah (Giant Kangaroo) 2) Auroch 3) Meiolania (Horned [...]

Over the past 8–9 fishing seasons, recruitment has declined in all of the major rock lobster (Jasus edwardsii) fisheries in south-eastern Australia. This has translated into declines in commercial catch rates. In some regions, this decline has been rapid. For example, catch rate in the southern zone fishery of South Australia has decreased by 65% [...]

Once abundant in European waters, the numbers of European eels have fallen drastically since the 1970s, by as much as 99% according to some estimates. Besides dams, turbines, and fishing, a number of factors, including a recently introduced parasite, chemical pollutants, and possible changes in ocean currents, are all suspected of playing a role in [...]

The Adirondack Mountains in New York State have a varied surficial geology and chemically diverse surface waters that are among the most impacted by acid deposition in the U.S. No single Adirondack investigation has been comprehensive in defining the effects of acidification on species diversity, from bacteria through fish, essential for understanding the full impact [...]

Owing to exceptional biomolecule preservation, fossil avian eggshell has been used extensively in geochronology and palaeodietary studies. Here, we show, to our knowledge, for the first time that fossil eggshell is a previously unrecognized source of ancient DNA (aDNA). We describe the successful isolation and amplification of DNA from fossil eggshell up to 19 ka [...]
