The purpose of this book is to
provide you with a bit more information about the organisms maintained at the ASLC so that you
may deepen your understanding and appreciation of them.
However, as a prelude to the more species-specific information contained in this document, there
are three short chapters...

This proposal by the Coniferous Forest Biome investigators requests support
for the third and fourth years of a highly integrated series of investigations
within the Ecosystem Analysis program of the United States effort under the
International Biological Program. The program for the Coniferous Forest Biome
has been approved by the...
The Pacific Coast Groundfish Fishery harvests a diverse and large grouping of fishes, but it did not become heavily fished until around WWII. This makes the groundfish fishery a comparatively young fishery. Despite its youth, it is one of the largest and most lucrative fisheries in Oregon—with a current harvest...
Three sympatric species of Ips, colonizing Sitka spruce, were
investigated with regard to their infestation habits, stridulating
apparatus and acoustic signals. The above phenomena are evaluated
qualitatively and/or quantitatively and the acoustic signal differences
are proposed as a possible factor for maintaining species isolation,
although function is not shown.
Field...
We report the development of a numerical model simulating vertical movement of the
cyanobacterium Trichodesmium spp. Given a range of physiological parameters derived from the literature,
resultant model solutions allow us to explore the ecological significance of vertical migration
by Trichodesmium colonies in a stratified oligotrophic oceanic system such as...
Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is...
There is a critical need to understand the impact rural community health coalitions can have on their communities when there is a willingness and drive from community members to share resources and provide supports. This oral history will provide the Live Longer Lebanon Community Health Coalition with a document that...
I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
A variety of macromolecules labeled with FITC (fluorescein isothiocyanate), including
carbohydrates (dextran) and proteins (ferritin, casein, albumin, concavalin A), spanning a range of
molecular weights from 55 to 2000 kD, were actively ingested by marine heterotrophic flagellates at
substrate concentrations of 1 to 10 mg/L. The uptake capacity for the...
