Researchers at the Smithsonian Tropical Research Institute and colleagues compared fossil porcupine fish jaws and tooth plates collected on expeditions to Panama, Colombia, Venezuela and Brazil with those from museum specimens and modern porcupine fish, revealing three new species.
The sungazer (Smaug giganteus), a dragon-like lizard species endemic to the Highveld regions of South Africa, is facing an assault on two fronts as farming and industrialization encroaches on its natural habitat -- which already consist of only a several hundred square kilometers globally -- while the illegal global pet trade is adding pressure on pushing the species into extinction.
Scientists at the University of Stirling have discovered a new type of plant growing in Shetland -- with its evolution only having occurred in the last 200 years.
A new marsupial-like carnivorous animal that lived more than 40 million years ago in what is now Turkey may have evolved in the absence of competition from placental mammals, according to a study published Aug. 16, 2017, in the open-access journal PLOS ONE by Murat Maga from University of Washington, US and Robin Beck from University of Salford, UK.
New technologies for analyzing DNA may transform how imperiled species are considered and managed for conservation protection, according to a study published today in the journal Science Advances and led by the University of California, Davis. These technologies can be applied to a wide range of species around the world -- from mushrooms to walruses -- but the study focuses on two iconic species of Pacific salmon: steelhead and chinook.
A Triceratops or Tyrannosaurus rex bulling its way through a pine forest likely dislodged flowers that 100 million years later have been identified in their fossilized form as a new species of tree.
For the first time, Jothi Yuvaraj and colleagues at Lund University, Sweden, have identified the corresponding pheromone receptors (PRs) from a primitive leafminer moth, called Eriocrania semipurpurella. Then, they show that these receptors also respond to plant odors and propose a scenario in which pheromone receptors evolved from plant odor receptors.
Researchers using Los Alamos' unique neutron-imaging and high-energy X-ray capabilities have exposed the inner structures of the fossil skull of a 74-million-year-old tyrannosauroid dinosaur nicknamed the Bisti Beast in the highest-resolution scan of tyrannosaur skull ever done.
New research out of Boyce Thompson Institute reveals surprising insights into the genetic exchange along the Silk Road that brought us the modern apple.
A new species of damselfly from the Cretaceous period has been named after the iconic naturalist and TV presenter Sir David Attenborough.
