Latest Pinyon pine Stories
Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.
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.
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.
By Hazlehurst, John During the last 10 years, mountain pine beetles have killed more than 1.5 million acres of lodgepole pines statewide. Summit County, home to Colorado's ski industry, has been particularly hard hit.
An ability to avoid the plant equivalent of vapor lock and a favorable evolutionary history may explain the unusual drought resistance of junipers, some varieties of which are now spreading rapidly in water-starved regions of the western United States, a Duke University study has found.
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 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...
