Agricultural Expansion In Amazon Will Only Decrease Productivity
2013-05-10 09:45:13

Widespread agricultural expansion in Brazil destroys equally as much rainforest, negating any benefits for the region. In fact, researchers, publishing a paper in the journal Environmental Research Letters, have called the practice a “no-win situation.”

Lake Elgygytgyn
2013-05-10 05:02:04

An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago.

Making Four New Dinosaur Species Out Of One
2013-05-09 14:01:38

Thanks to hard work and determination, a University of Alberta researcher has found four new species of armored dinosaurs that were originally considered to be the same species.

Atlantis Found In Brazil Via Discovery Of Ancient Granite Rock

A team of experts from Brazil and Japan say they have discovered their version of Atlantis, or at least an ancient piece of granite that was part of a continent that disappeared nearly a hundred million years ago when Africa and South America separated.

Mass Extinction Made Space Dinosaur Forerunners

Approximately 252 million years ago, during the world’s largest mass extinction event, nine out of ten species vanished from the planet. Scientists now believe this may have made space for dinosaurs' earliest forerunners.

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...
