Lake Towuti
2014-03-25 12:05:49

Brown University Using sediments from a remote lake, researchers from Brown University have assembled a 60,000-year record of rainfall in central Indonesia. The analysis reveals important new details about the climate history of a region that wields a substantial influence on the global climate as a whole. The Indonesian archipelago sits in the Indo-Pacific Warm Pool, an expanse of ocean that supplies a sizable fraction of the water vapor in Earth's atmosphere and plays a role in...

Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

life reconstruction of the new oviraptorosaurian dinosaur species Anzu wyliei
2014-03-20 04:30:15

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal PLOS ONE have discovered a new bird-like dinosaur named Anzu wyliei. The fossil skeletons of Anzu were discovered in North and South Dakota underneath 66-million-year-old rocks. Anzu gives scientists the chance to study the anatomy and evolutionary relationships of Caenagnathidae, which is a group of theropod dinosaurs. “Anzu is far and away the most complete caenagnathid that has ever been...

Brett Smith for redOrbit.com - Your Universe Online The reexamination of a dinosaur skull found in Alaska has revealed that it may have belonged to a “smaller cousin” of Tyrannosaurs Rex – not a completely distinct species as originally believed. According to a report on the examination published on Wednesday in the journal PLoS ONE, the skull belonged to a lineage of theropods, or “beast feet,” dinosaurs that includes T. Rex. With most T. Rex fossils coming from temperate...

redOrbit Staff & Wire Reports - Your Universe Online By studying thousands of canopy tree species in the western Amazon, researchers from the Carnegie Institution for Science’s Department of Global Ecology have uncovered geographically nested patterns of chemical traits they say will help determine how the ecosystem will respond to changes in land use and climate. Writing in the March 3 edition of the Proceedings of the National Academy of Sciences (PNAS), the study authors set...

Bering Land Bridge Was Home To Early Natives For 10,000 Years: Study
2014-02-28 09:47:53

April Flowers for redOrbit.com - Your Universe Online After the ancestors of modern day Native Americans left Asia, they spent approximately 10,000 years living in the shrubby lowlands of the Bering land bridge, according to genetic and environmental evidence. There is no available archaeological evidence, however, because it drowned beneath the Bering Sea when the sea levels rose about 18,000 years ago. Dennis O'Rourke, a University of Utah anthropologist, worked with archaeologist...

Peru Ice Cap Shrinking Due To Warming Temps, Not Less Snowfall
2014-02-26 12:56:35

Brett Smith for redOrbit.com - Your Universe Online When we think about how climate change is shrinking glaciers around the world – we are probably imagining the massive sheets of ice around the Earth’s polar regions. However, glaciers do exist in tropical latitudes, albeit at extremely high elevations, and a new study in the journal Geology has found that one of these tropical glaciers is shrinking as a result of warming temperatures – not lower snowfall levels as some scientists...

Australian Rock Determined To Be Oldest Material Formed On Earth
2014-02-24 13:04:03

[ Watch the Video: The Oldest Rock On Earth ] Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature Geoscience, say a rock in Australia is helping to paint a picture of how our planet became habitable 4.4 billion years ago. The team found data from a tiny fragment of zircon that confirms the Earth’s crust first formed 4.4 billion years ago, which is just 160 million years after the formation of the Solar System. John Valley,...

Unstable Atlantic Deep Ocean Circulation Under Future Climate Conditions
2014-02-21 11:46:51

The University of Bergen A new study looking at past climate change, asks if these changes in the future will be spasmodic and abrupt rather than a more gradual increase in the temperature Today, deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally. In the process, this impacts on the circum-Atlantic climate, regional sea level, and soak up much of the excess atmospheric carbon dioxide from industrialization — helping to moderate the...

Ups And Downs Of Early Atmospheric Oxygen
2014-02-20 10:41:29

Iqbal Pittalwala - University of California - Riverside UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years A team of biogeochemists at the University of California, Riverside, give us a nontraditional way of thinking about the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth...

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...
