Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...
The Antarctic contribution to sea level is a balance between ice loss along the margin and accumulation in the interior. Accumulation records for the past few decades are noisy and show inconsistent relationships with temperature. We investigate the relationship between accumulation and temperature for the past 31 ka using high-resolution records...

This research provides information on the distribution of an
unexploited Roosevelt elk population in unaltered habitat in Olympic
National Park. Radio-telemetry was used to document home range and
habitat use by 11 adult cow elk in the Hoh Valley during March 1978,
from 10 June-15 September 1978, and from 1...
Populations of Dendroctonus ponderosae Hopkins from three pine
hosts, Pinus ponderosa Laws., P. contorta Dougl. and P. monticola
Dougl., were sampled with regard to their acoustic signals, the
morphology of their stridulatory apparatus and some aspects of their
emergence behavior. Comparisons of these characteristics were made
between samples from different...
The dilute sulfuric acid hydrolysis of annual rye grass (Lolium
multiflorum) straw was investigated. The straw was hydrolyzed in a
stainless steel pressure bomb at 121° C, 135° C, and 150° C with
0.5 to 3.0 percent sulfuric acid for time periods up to 40 minutes.
These conditions resulted in...
There are six types of Cl. botulinum (Types A, B, C, D, E,
and F). The differentiation between these types is based upon the
antigenic structure of the toxin. Many strains of these various types
have been isolated. In addition, a number of nontoxigenic "type Elike"
strains have come to...
