A University of Montana researcher has discovered that mountain pine beetles may avoid certain trees within a population they normally would kill due to genetics in the trees.
A study led by Indiana University suggests that computer models used to predict the spread of epidemics from climate change -- such as crop blights or disease outbreaks -- may not take into account an important factor in predicting their severity.
Forests in the eastern United States may have had it easy compared to their western counterparts, with the intense, prolonged droughts and wildfires that have become typical out west in recent years. But as the climate changes over time, eastern forests are also likely to experience longer droughts. And although wildfires are comparatively rare, prescriptive fires are increasingly used in the east. How will these forests fare in the future? A new study from the University of Illinois provides answers.
Timber harvested illegally under fraudulent permits is undercutting conservation efforts in the Brazilian Amazon, new research by an international collaboration shows.
Seabirds such as gulls can be key indicators of environmental change as their populations respond to shifts in their ocean habitat over time. A new study from The Auk: Ornithological Advances investigates how several species have responded to changing environmental conditions in the Arctic over the last four decades. The authors find that a warming ocean is directly and indirectly affecting seabird populations in Alaska.
The 1987 Montreal Protocol and the 1997 Kyoto Protocol called for countries around the world to phase out substances that deplete the ozone layer, but many HVAC systems still use synthetic refrigerants that violate those international agreements and inflict environmental damage. Recently, Iranian researchers investigated how natural refrigerants could be used in geothermal heat pumps to reduce energy consumption and operating costs. They report their findings in the Journal of Renewable and Sustainable Energy.
The unusual timing of highly-productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. In a new study published today in Nature Communications, an international group of researchers shows that this connection exists, but is much more complex than widely supposed. Whether increasing meltwater has a positive or negative effect on summertime phytoplankton depends on the depth at which a glacier sits in the ocean.
Trees are growing more rapidly due to climate change. This sounds like good news. After all, this means that trees are storing more carbon dioxide from the atmosphere in their wood and hence taking away the key ingredient in global warming. But is it that simple? A team from the Technical University of Munich (TUM) analyzed wood samples from the oldest existing experimental areas spanning a period of 150 years -- and reached a surprising conclusion.
On average 68 percent of all investigated foreign capital to sectors associated with deforestation of the Amazon rainforest was transferred through tax havens. And 70 percent of the known fishing vessels involved in illegal, unreported and unregulated (IUU) fishing are, or have been, registered in tax havens.
Younger generations of religious Americans tend to closely harbor concerns for the environment via stewardship more so than older parishioners, according to a study by a University of Kansas researcher.
