Trees and the insects that eat them wage constant war. Insects burrow and munch; trees deploy lethal and disruptive defenses in the form of chemicals. But in a warming world, where temperatures and seasonal change are in flux, the tide of battle may be shifting in some insects' favor, according to a new study. In a report published today (Dec. 31, 2012) in the Proceedings of the National Academy of Sciences, a team of scientists from the University of Wisconsin-Madison reports a rising...
New research concludes that a one-two punch of drought and mountain pine beetle attacks are the primary forces that have killed more than 2.5 million acres of pinyon pine and juniper trees in the American Southwest during the past 15 years, setting the stage for further ecological disruption. The widespread dieback of these tree species is a special concern, scientists say, because they are some of the last trees that can hold together a fragile ecosystem, nourish other plant and animal...
Siberian pine nut oil.org releases study in English proving that Siberian pine nut oil enriched with pine resin excellently fights parasites. New York, NY (PRWEB) May 21, 2012 In the new electronic testing of food products with regard to their antiparasitic effect, 46 types of edible and aromatic oils were examined. The testing demonstrated that Siberian pine nut oil enriched with pine resin possesses elevated antiphrastic properties. Here, then, lies the secret of its cleansing,...
Shortleaf pine-hardwood ecosystem restoration following insect outbreak Research by USDA Forest Service Southern Research Station (SRS) scientists shows that the impacts of recent outbreaks of southern pine beetle further degraded shortleaf pine-hardwood forest ecosystems in the southern Appalachian region. The authors suggest that cutting and burning these sites reduces heavy fuel loads, improves soil nutrient status, and opens the canopy for restoration of these shortleaf pine...
More than 50 years of genetics work to increase loblolly pine production in the Southeast has improved the trees’ ability to act as carbon sinks that mitigate climate change, according to a new study by North Carolina State University researchers. “We’ve been working to create trees that grow faster and produce more wood, and what this research shows is that at the same time we’re enhancing environmental quality by scrubbing as much carbon out of the atmosphere as we possibly...
A new study published in the Proceedings of the Royal Society B has found that human noise like traffic can have ripple effects on plants. Lead author Clinton Francis of the National Evolutionary Synthesis Center (NESCent) in Durham, North Carolina, said the consequences of noise could last for decades, even after the source of the noise goes away. Previous studies found that some animals increase in numbers near noisy sites, while others decline, but the results of the new study found...
A new study of the composition of pine nuts, including those associated with "pine mouth," leaves unsolved the decade-old mystery of why thousands of people around the world have experienced disturbances in taste after eating pine nuts. The report on pine nuts or pignolia — delicious edible nuts from pine trees enjoyed plain or added to foods ranging from pasta to cookies — appears in ACS' Journal of Agricultural & Food Chemistry. Ali Reza Fardin-Kia, Sara M. Handy and Jeanne I....

Researchers see increase in snowpack under bare dead pine trees, earlier melt under dead trees with red needlesA new University of Colorado Boulder study indicates the infestation of trees by mountain pine beetles in the high country across the West could potentially trigger earlier snowmelt and increase water yields from snowpack that accumulates beneath affected trees.Led by CU-Boulder geological sciences department doctoral student Evan Pugh, the study was undertaken near Grand Lake,...
A University of Alberta-led research team has determined that the mountain pine beetle has invaded jack pine forests in Alberta, opening up the possibility for an infestation that could stretch across the Prairies and keep moving east towards the Atlantic. A group of U of A tree biologists and geneticists discovered that, as the mountain pine beetle spread eastward from central British Columbia, it successfully jumped species from its main host, the lodgepole pine, to the jack pine. Jack pine...

The Pinyon Jay (Gymnorhinus cyanocephalus), occurs in western North America from central Oregon to northern Baja California and east as far as western Oklahoma though it wanders further afield out of the breeding season. It lives in foothills where the pinyon pines (Pinus edulis and Pinus monophylla) occur. It was first collected and described along the Maria River in northern Montana in 1833. The Pinyon Jay is between the North American Blue Jay and the Eurasian Jay in size. Its overall...
The Douglas Squirrel, Tamiasciurus douglasii, is a pine squirrel found in the Pacific coastal states and provinces of North America. Douglas Squirrels live in coniferous forests, from the Sierra Nevada mountains of California northwards to coastal British Columbia. They prefer old-growth or mature second-growth forest. It is a small, lively, bush-tailed tree squirrel. Adults are (including tail) about 13 inches long. They weigh between 5 and 10.5 ounces. Their appearance varies according...
The Clark's Nutcracker (Nucifraga columbiana) is a large passerine bird in the family Corvidae. It is slightly smaller than its Eurasian relative, Spotted Nutcracker (N. caryocatactes). It is ashy-grey all over except for the black-and-white wings and central tail feathers (the outer ones are white). The bill, legs and feet are also black. This bird is found in western North America from British Columbia and western Alberta in the north to Baja California and western New Mexico in the...
