To determine if squirrels (Sciurus douglasii var.) cut cones before the seeds are ripe, a series of collection points was established in the Willamette Valley and the Cascade Mountains in the summer of 1954. The areas were inspected at intervals during August, September and October of 1954, and freshly cut...
Radiation damage caused by fission fragments to metal surfaces is an important research topic. Thin titanium foils were irradiated with a continuous wave beam of 132 MeV ¹³²Xe+²⁹ at the current intensity of 2 pnA. Pre- and post-irradiated surface topologies were investigated using atomic force microscopy and the observed defects...
Multivariate statistical treatments of large data sets in sedimentary geochemical and other fields are
rapidly becoming more popular as analytical and computational capabilities expand. Because
geochemical data sets present a unique set of conditions (e.g., the closed array), application of generic
off-the-shelf applications is not straightforward and can yield misleading...

Identifying the ecological and evolutionary mechanisms that determine biological diversity is a central question in ecology. In microbial ecology, phylogenetic diversity is an increasingly common and relevant means of quantifying community diversity, particularly given the challenges in defining unambiguous species units from environmental sequence data. We explore patterns of phylogenetic...
