Massive Spruce Beetle Outbreak In Colorado Tied To Drought
2013-10-10 13:03:38

University of Colorado Boulder A new University of Colorado Boulder study indicates drought high in the northern Colorado mountains is the primary trigger of a massive spruce beetle outbreak that is tied to long-term changes in sea-surface temperatures from the Northern Atlantic Ocean, a trend that is expected to continue for decades. The new study is important because it shows that drought is a better predictor of spruce beetle outbreaks in northern Colorado than temperature alone,...

Dramatic shifts in the planet's climate and geography over millions of years changed the course of evolutionary history for conifer trees, according to a Yale paper in the Proceedings of the National Academy of Sciences. Yale researchers examined the fossil record and genetic makeup of 489 out of more than 600 living conifer species and discovered that while most conifers belong to ancient lineages, most Northern Hemisphere species, including the majority of pines and spruces, appeared...

[ Watch the Video] Until now, it was presumed that the last glacial period denuded the Scandinavian landscape of trees until a gradual return of milder weather began and melted away the ice cover some 9000 years ago. That perspective is now disproved by research headed by Professor Eske Willerslev from the Centre for GeoGenetics, University of Copenhagen, Denmark, Laura Parducci from the University of Uppsala, Sweden, and Inger Greve Alsos from Tromsø University Museum,...

Earlier springs could enhance xylem growth in black spruce"”but colder summers could negate that With an increasingly warmer climate, there is a trend for springs to arrive earlier and summers to be hotter. Since spring and summer are the prime growing seasons for plants"”when flowers bloom and trees increase in girth and height"”do these climate changes mean greater seasonal growth for plants? This is a critical question for forest management, especially in the boreal...

The natural product wood grows in locations with different climate, soil and environmental conditions. These differences influence its properties as construction material: "Scandinavian spruce, for instance, has smaller knots and lower raw densities than spruce coming from central Europe, and this results in different strength and stiffness values," explains Professor Jan-Willem van de Kuilen from the Department of Wood Technology at TUM. That is why, to ensure the stability of wooden...

The Blue Spruce or Colorado Spruce (Picea pungens), is a species of spruce native to western North America, from southeast Idaho and southwest Wyoming, south through Utah and Colorado to Arizona and New Mexico. It grows at high altitudes from 6,000 to 10,000 feet in altitude, though unlike Engelmann Spruce in the same area, it does not reach the alpine tree-line. It is most commonly found growing along stream sides in mountain valleys, where moisture levels in the soil are greater than the...
