The impact of population abundance on the deposit-
feeding rate of Mediomastus ambisetu (Capitellidae:
Polychaeta) was studied in still-water laboratory experiments.
Mean individual pellet production rate (mg worm¯¹ d¯¹) decreased
monotonically with increasing worm abundance in the
range of 6.5 X 10³ to 1.3 X 10⁵ worms m¯². Worms fed...
The atmospheric flux of methane from the oceans is largely mitigated through microbially
mediated sulphate-coupled methane oxidation, resulting in the precipitation of authigenic
carbonates. Deep-sea carbonates are common around active and palaeo-methane seepage,
and have primarily been viewed as passive recorders of methane oxidation; their role as active
and unique...

Background:
The language of “participant-driven research,” “crowdsourcing” and “citizen science” is increasingly being used to encourage the public to become involved in research ventures as both subjects and scientists. Originally, these labels were invoked by volunteer research efforts propelled by amateurs outside of traditional research institutions and aimed at appealing...
Facultative/winter six-row malting barley is a distinct elite germplasm pool and a valuable resource that may prove useful in meeting the challenges of climate change. To preserve its diversity and make it accessible to the research and agricultural communities, the Oregon State University and University of Minnesota barley breeding programs...
Although most eastern North Pacific (ENP) gray whales feed in the Bering, Beaufort, and Chukchi Seas during summer and fall, a small number of individuals, referred to as the Pacific Coast Feeding Group (PCFG), show intra- and interseasonal fidelity to feeding areas from northern California through southeastern Alaska. We used...
Changes in dietary selenium and selenoprotein status may influence both anti- and pro-cancer pathways, making the outcome of interventions different from one study to another. To characterize such outcomes in a defined setting, we undertook a controlled hepatocarcinogenesis study involving varying levels of dietary selenium and altered selenoprotein status using...
The use of DNA markers in public sector plant breeding is now the norm. Such markers are common across breeding programs and this commonality enables and enhances collaboration. Therefore, large collaborative research projects that measure several phenotypes across multiple environments coupled with the expanding amount of genotype data attainable with...
Crystallographic studies of ligands bound to biological macromolecules (proteins and nucleic acids) represent an important source of information concerning drug-target interactions, providing atomic level insights into the physical chemistry of complex formation between macromolecules and ligands. Of the more than 115,000 entries extant in the Protein Data Bank (PDB) archive,...
