A question of height
Intelligent countryside management could improve the survival chances of animal and plant species threatened by climate change. The creation of small heat-shielded habitats and better links between habitats would counteract a moderate temperature increase, and give threatened species more time to adapt better and/or to migrate to cooler regions. This is the conclusion drawn by scientists at the Helmholtz Center for Environmental Research from a British study on saving the Large Blue butterfly.

LRO's first moon images
NASA's Lunar Reconnaissance Orbiter has transmitted its first images since reaching the moon on June 23. The spacecraft's two cameras, collectively known as the Lunar Reconnaissance Orbiter Camera, or LROC, were activated June 30. The cameras are working well, and have returned images of a region in the lunar highlands south of Mare Nubium (Sea of Clouds).

Pacific Northwest forests could store more carbon, help address greenhouse issues
The forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in coming years, a recent study concludes, if they are managed primarily for that purpose through timber harvest reductions and increased rotation ages.

Ferns took to the trees and thrived
As flowering plants like giant trees quickly rose to dominate plant communities during the Cretaceous period, the ferns that had preceded them hardly saw it as a disappointment.

Evolution: Crabs go deep to avoid hot water
Researchers from the National Oceanography Center, Southampton, have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant -- the king crab. The results, published this week in the Journal of Biogeography, reveal temperature as a driving force behind the speciation and radiation of a major seafloor predator -- globally, and over tens of millions of years of Earth's history.

Climate change and the mystery of the shrinking sheep

Climate change and the mystery of the shrinking sheep
Changing winter conditions are causing Scotland's wild Soay sheep to get smaller despite the evolutionary benefits of having a large body, researchers report in a study that shows how climate change can trump natural selection.

Earth's most prominent rainfall feature creeping northward
The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years. If the band continues to migrate at just less than a mile a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator may be starved of freshwater by midcentury or sooner.

Desert rhubarb -- a self-irrigating plant
Researchers from the department of science education-biology at the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb, which enables it to harvest 16 times the amount of water than otherwise expected for a plant in this region based on the quantities of rain in the desert. This is the first example of a self-irrigating plant worldwide.

The least sea ice in 800 years
New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now. The research results from the Niels Bohr Institute, among others, are published in the scientific journal Climate Dynamics.

Plants put limit on ice ages
When glaciers advanced over much of the Earth's surface during the last ice age, what kept the planet from freezing over entirely? This has been a puzzle to climate scientists because leading models have indicated that over the past 24 million years geological conditions should have caused carbon dioxide levels in the atmosphere to plummet, possibly leading to runaway "icehouse" conditions. Now researchers writing in Nature report on the missing piece of the puzzle -- plants.

Plants save the earth from an icy doom
Fifty million years ago, the North and South poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers at Yale University, the Carnegie Institution of Washington and the University of Sheffield now show that land plants saved the Earth from a deep frozen fate by buffering the removal of atmospheric CO2 over the past 24 million years.

Mangrove-dependent animals globally threatened
An assessment in the July/August issue of BioScience finds that substantial numbers of terrestrial vertebrates are restricted to mangrove forests. Many of these specialized species are listed as threatened by the International Union for the Conservation of Nature. Prospects for mangrove-restricted animals are bleak, because more than two percent of mangrove forests are lost each year.

A young brain for an old bee
Scientists have found that by switching the social role of honey bees, aging honey bees can keep their learning ability intact or even improve it. The research team is hoping to use them as a model to study general aging processes in the brain and how to prevent or ameliorate cognitive impairments associated with old age. The results will be presented at the Society for Experimental Biology Meeting on Wednesday, July 1.

Key to evolutionary fitness: Cut the calories
Charles Darwin postulated that animals eat as much as possible while food is plentiful, and produce as many offspring as this would allow. However, new research shows that, even when food is abundant, intake reaches a limit. Dr. Teresa Valencak will discuss the theory that animals actively limit their energy turnover to maintain a higher level of reproductive success over their lifetime at the Society for Experimental Biology Meeting on Wednesday, July 1.

UB geologists to help communicate the dangers of Colombian volcano
During the past decade, residents of Pasto, Colombia, and neighboring villages near Galeras, Colombia's most dangerous volcano, have been threatened with evacuation, but compliance varies. With each new eruption Colombian officials become increasingly concerned about the safety of the residents who live within striking there. Now, geologists from the University at Buffalo and the Universidad de Nariņo have organized a special workshop in Colombia designed to tackle the communication issue.

Super-size deposits of frozen carbon threat to climate change
The vast amount of carbon stored in the Arctic and boreal regions of the world is more than double that previously estimated, according to a study published this week. The new estimate is over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere.

Your own private global warming
Researchers from the British Antarctic Survey subjected species found in Antarctic waters to increasing levels of water temperature to learn how well they would cope with a warmer ocean. The study, to be presented at the Society for Experimental Biology meeting on Tuesday, June 30, shows that several of these species are already living really close to their upper temperature range, and that further increases could easily provoke serious ecological imbalances in this region.
