We quantified both in situ predation on Pacific herring (Clupea haregus pallasi ) larvae by soft-bodied zooplankton, and microzooplankton prey of herring larvae in Kulleet Bay, Vancouver Island, British Columbia. Samples were collected at 0 to 5 m depth daily at peak larval hatching from 14 to 21 April 1985....
Abnormalities including contortion of the body and reduction of the jaws and pectoral
fins occurred among 2-25% of the yolk-sac Pacific herring larvae Clupea harengus pallasi collected in 1985 from Kulleet Bay, a spawning area on Vancouver Island, British Columbia. An additional 4-68% of the post-yolk-sac larvae had underdeveloped lower...
This data report includes documentation of the Coastal Mixing and Optics (CMO) Experiment inherent optical property surveys on the continental shelf and slope in the Mid-Atlantic Bight south of Cape Cod, Massachusettes, USA. The surveys were conducted aboard the R/V Endeavor during two physical oceanography cruises: E9608 (14 August to...
This investigation is an exploration of the use of inherent optical properties towards further elucidation of coastal circulation processes occurring on the continental shelf and slope in the Middle Atlantic Bight, south of Cape Cod Massachusetts, during 14-Aug to 1-Sep 1996 and 25-Apr to 15-May 1997. Assessing the possibility of...
Geochemical characterization methods are commonly used in the reconstruction of prehistoric raw material use and procurement systems. Trace element studies of lithic source material and artifacts, specifically those made of obsidian, can reveal important information about the environmental and cultural factors which influence the prehistoric distribution of raw material. The...
The hump-shaped relationship that predicts highest species richness (species/unit area) at intermediate levels of productivity was examined for woody plants across the Pacific and Inland Northwest of the U.S. Many studies have examined this relationship at regional scales, but commonly use species range maps and surrogate measures of productivity (e.g....
Aesthetics should be emphasized as much as possible in a design project without
exceeding scope, budget, or schedule to satisfy the stakeholders involved. There
is a rising trend of increased emphasis on aesthetics. This trend of using various
techniques to help structures blend in or contribute to the surrounding
environment...
The Gene Ontology (GO) Consortium (http://www.geneontology.org) (GOC) continues to develop,
maintain and use a set of structured, controlled
vocabularies for the annotation of genes, gene
products and sequences. The GO ontologies
are expanding both in content and in structure.
Several new relationship types have been introduced
and used, along with...
Endogenous small RNAs (endo-siRNAs) interact with Argonaute (AGO) proteins to mediate
sequence-specific regulation of diverse biological processes. Here, we combine deep-sequencing and
genetic approaches to explore the biogenesis and function of endo-siRNAs in C. elegans. We describe
conditional alleles of the dicer-related helicase, drh-3, that abrogate both RNA interference and...
A replicated before–after-control-impact study was used to test effectiveness of Oregon’s (USA) riparian
protection measures at minimizing increases in summer stream temperature associated with timber harvest.
Sites were located on private and state forest land. Practices on private forests require riparian management
areas around fish-bearing streams; state forest’s prescriptions are...
