John Wiley and Sons Inc. and the Royal Geographical Society (with IBG) announced today the launch of the Society’s first fully open access journal: Geo: Geography and Environment.
The American Geophysical Union (AGU) today announced that John Orcutt, a distinguished professor of Geophysics at the Scripps Institution of Oceanography and former president of AGU, will serve as the inaugural editor of its newest open access, peer-reviewed journal, Earth and Space Science.

Researchers who transplanted combinations of wild, domesticated, and domesticated-wild hybridized populations of a fish species to new environments found that within 5 to 11 generations, selection could remove introduced foreign genes from wild populations that hybridized with domesticated populations.
As soon as lava flows from a volcano, exposure to air and wind causes it to start to cool and harden. Rather than hardening evenly, the energy exchange tends to take place primarily at the surface. The cooling causes a crust to form on the outer edges of the lava flow, insulating the molten lava within. This hardened lava shell allows a lava flow to travel much further than it would otherwise, while cracks in the lava’s crust can cause it to draw up short.
There is no published account where hippopotamuses are demonstrably shown swimming or floating at the surface of any body of water. But if they can’t swim, how did they reach and colonize islands?
John Wiley and Sons Inc. announced today its selection by the Association for the Sciences of Limnology and Oceanography (ASLO) to publish their highly regarded portfolio of journals focused on marine and inland water systems.
Scientists who studied long-lived diving birds, which represent valuable models to examine aging in the wild, found that blood oxygen stores, resting metabolism and thyroid hormone levels all declined with age, although diving performance did not. Apparently, physiological changes do occur with age in long-lived species, but they may have no detectable effect on behavioral performance.
A new Journal of Evolutionary Biology study provides evidence that physical barriers formed by oceans can influence language diversification.
Butterflies' Evolutionary Responses to Warmer Temperatures May Compromise Their Ability to Adapt to Future Climate Change
Members of the brown argus butterfly species that moved north in response to recent climate change have evolved a narrower diet dependent on wild Geranium plants, UK researchers report. However, butterflies that did not move north have more diverse diets, including plants such as Rockrose that are abundant in southern parts of the UK.
While the sinking of the Titanic in 1912 is typically blamed on human, design and construction errors, a new Significance paper points to 2 other unfavorable factors outside human control: there were a greater number of icebergs than normal that year, and weather conditions had driven them further south, and earlier in the year, than was usual.
New research in gorillas that were affected by an Ebola virus outbreak shows that disease can influence reproductive potential, immigration and social dynamics, and it highlights the need to develop complex models that integrate all the different impacts of a disease.
Researchers who analyzed the vulnerability of ecosystems to climate change have found that between 10 and 28% of the world’s terrestrial vegetated area can be considered refugia, depending on whether or not wilderness areas are considered. Refugia are areas of biological diversity where natural environmental conditions remain relatively constant during times of great environmental change.
John Wiley & Sons, Inc., today announced a continued increase in the proportion of its journal titles indexed in the 2014 release of Thomson Reuters Journal Citation Reports® (JCR). A total of 1,202 Wiley titles (approximately 70%) were indexed, up from 1,193 in the 2012 JCR, and including 13 titles which have been indexed for the first time.
Growing consensus on climate and land use change means that it is reasonable to assume, at the very least, that flood levels in a region may change. Then why, ask Rosner et al. in a new study, do the dominant risk assessment techniques used to decide whether to build new flood protection infrastructure nearly always start with an assumption of “no trend” in flood behavior?
A simple and humane technique may be an effective strategy to reduce human encounters with sharks without harming populations of threatened shark species.
A Marine Mammal Science analysis on failed shark attacks on the approximately 120 Atlantic spotted dolphins that are residents of the waters near Bimini, The Bahamas, has found that a total of 14 dolphins (15% of 92 cataloged animals) showed some sign of shark attack, and a further 15 (16%) exhibited scars that could not conclusively be classified as shark induced or not.
Study Provides Insights on Whale Shark Populations and Evidence for their Historic Rise and Recent Decline
In the largest study on the genetics of whale sharks conducted to date, researchers found that the world’s biggest fish likely exist in 2 distinct populations with minimal connectivity between the Indo-Pacific and the Atlantic Ocean. The findings suggest that mixing of whale sharks between the Indian and Atlantic was and is rare.
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say.
A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.
Storm-triggered landslides cause loss of life, property damage, and landscape alterations. For instance, the remnants of Hurricane Camille in 1969 caused 109 deaths in central Virginia, after 600 mm of rain fell in mountainous terrain in 6 hours. More recently, on 8 August 2010, a rainstorm-induced landslide devastated the Chinese county of Zhouqu, causing more than 1000 deaths. A new modeling study by Ren examines the multiple factors, both natural and human caused, that came together to produce this event.
The concentrations of many historically used, and now widely banned, pesticides and other toxic chemicals—called legacy contaminants—can become magnified in an animal that eats contaminated food; however, a new Environmental Toxicology & Chemistry study has found that Arctic mammals metabolize some currently used pesticides, preventing such ‘biomagnification.’
Both shale gas and conventional natural gas have a larger greenhouse gas footprint than do coal or oil, especially for the primary uses of residential and commercial heating.
Researchers have streamlined and simplified a process that uses extracts from seeds of Moringa oleifa trees to purify water, reducing levels of harmful bacteria by 90% to 99%. The hardy trees that are drought resistant are cultivated widely throughout many countries of Africa, Asia, and Latin America.
