An ancestor of the rabbit connects Europe and Asia

Science Daily - Tue, 01/26/2016 - 10:15
The species Amphilagus tomidai was recently discovered - an ancestor of the rabbit which lived in present-day Siberia during the Miocene, about 14 million years ago. The discovery of this mammal, belonging to a family which was thought to only exist in Europe, reveals that the two continents were presumably connected free of natural barriers due to the disappearance of the ancient Paratethys Sea. A study presents a new species, the Amphilagus tomidai, found in south-eastern Siberia (Russia) and dating back to the Middle Miocene, about 14 million years ago. The discovery of this mammal, an ancestor of the present-day rabbit, represents an important biogeographic link that confirms the widespread distribution of this group as well as the relationship between Asia and Europe during this period.

Climate change: Ocean warming underestimated

Science Daily - Mon, 01/25/2016 - 14:59
To date, research on the effects of climate change has underestimated the contribution of seawater expansion to sea level rise due to warming of the oceans. A team of researchers has now investigated, using satellite data, that this effect was almost twice as large over the past twelve years than previously assumed. That may result in, for example, significantly increased risks of storm surges.

The aftermath of 1492: Study shows how Native American depopulation impacted ecology

Science Daily - Mon, 01/25/2016 - 14:57
Among the Pueblo Indians of northern New Mexico, disease didn't break out until nearly a century after their first contact with Europeans, following the establishment of mission churches in the seventeenth century, a team of researchers has shown. The depopulation was so extreme it led to changes in forest fires in the region, they say.

Melting Greenland ice sheet may affect global ocean circulation, future climate

Science Daily - Fri, 01/22/2016 - 11:26
Scientists have determined that the influx of fresh water from the Greenland ice sheet is 'freshening' the North Atlantic Ocean and could disrupt the Atlantic Meridional Overturning Circulation, an important component of global ocean circulation that could have a global effect. Researchers say the it could impact the future climate in places such as portions of Europe and North America.

Water supplies in Tibet set to increase in the future

Science Daily - Wed, 01/20/2016 - 10:37
The Tibetan Plateau has long been seen as a “hotspot” for international environmental research, and there have been fears that water supplies in the major Asian rivers would drastically decline in the near future. However, new research now shows that water supplies will be stable and may even increase in the coming decades.

Assessing the impact of human-induced climate change

Science Daily - Wed, 01/20/2016 - 08:17
A new method is being applied to determine whether specific climate impacts can be traced to human-caused emissions. The past century has seen a 0.8°C (1.4°F) increase in average global temperature, and the overwhelming source of this increase has been emissions of greenhouse gases and other pollutants from human activities, they say.
