Zhang and Cai (2011) estimated moisture gradients during high-temperature drying of subalpine fir
(Abies lasiocarpa) through microscopic analysis.
is the dominant host of balsam woolly adelgid in Idaho  although grand fir has been reported to be a supportive host .
The combination of these variables with either slope or thermal aspect accounted for the distribution of willow, subalpine fir
, mountain mahogany, and antelope bitterbrush in proximity to forest cover.
In contrast, the thin bark of other species such as lodgepole pine (Pinus contorta), Englemann spruce (Picea sitchensis), and subalpine fir
(Abies lasiocarpa) suggest these species evolved under less frequent stand-replacing crown fires, indicating dense stands between fires may have been common in the past.
and mountain hemlock, for example, can attain ages of about 300 and 900 years, respectively.
The five of us thunder down the hillside, pushing through the tangle of rain-soaked subalpine fir
, menziesia, and young larch, skidding over roots and rocks with antenna held high.
Douglas-fir, western larch, and subalpine fir
have also increased substantially over the years, from 1 percent or less in 1976 to about 5 percent each in 1998.
At this elevation, Dry Lake Creek flows through a predominantly Engelmann spruce (Picea engelmannii Parry ex Engelm.) and subalpine fir
(Abies lasiocarpa (Hook.) Nutt.) forest, with some intermixed lodgepole pine (Pinus contorta Dougl.
grow arrow-straight from a forest floor of huckleberry and heather, beargrass and dwarf lupine.
Effects of population structure and cone production on outcrossing rates in Engelmann spruce and subalpine fir
. Evolution 41:124-136.
in balsam fir (Abies balsamea) we also found an eastern and western terpene type (20-45% and 30-55% [beta]-pinene, 5-35% and only a trace of car-3-ene, etc., respectively) and we could detect the introgression with interior subalpine fir
grows from Arizona's sky islands to arctic Alaska, but it is noticeably absent in much of California.
The Bingham fires are burning in patchy, subalpine fir
and lodgepole pine, with plenty of dead and fallen trees and accumulations of flammable debris on the ground.
Finding a rest on a steep hillside with grass and subalpine fir
is a challenge when you want to dial-in on a trophy mule deer buck.
