A ranunculalean liana stem from the cretaceous of British Columbia, Canada: Atli morinii gen. et sp nov.

Creator:: Smith, Selena Y., Little, Stefan A., Cooper, Ranessa L., Burnham, Robyn J., and Stockey, Ruth A.
Abstract:: Premise of research. The lianoid habit is found in 125 extant plant families and is most diverse and abundant in structurally complex forests, such as tropical forests. A stem with lianoid anatomy is described from Cretaceous sediments of Hornby Island, British Columbia. Methodology. The stem segment, 2.5 cm in diameter...

Benefits From R&D and Spill-Overs in Aquaculture: An Eu-15 Modelling Approach

Creator:: Guettler, Stefan and Mueller, Rolf A. E.
Abstract:: Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. In the EU aquaculture production has grown strongly in some countries, such as Spain and Greece, but was flat at a low level in others, such as in Germany,...

Managing early succession for biodiversity and long-term productivity of conifer forests in southwestern Oregon

Creator:: Bormann, Bernard T., Darbyshire, Robyn L., Homann, Peter S., Morrissette, Brett A., and Little, Susan N.
Abstract:: Early-successional stages have been truncated and altered in many western U.S. forest landscapes by planting conifers, controlling competing vegetation, suppressing fire, and focusing on maintaining late-seral species and undisturbed riparian zones. Declining area of early-successional stages may be reducing resilience and sustainability on landscapes that experience elevated disturbance related to...

Microbes, macrofauna, and methane: A novel seep community fueled by aerobic methanotrophy

Creator:: Thurber, Andrew R., Levin, Lisa A., Rowden, Ashley A., Sommer, Stefan, Linke, Peter, and Kroeger, Kerstin
Abstract:: During the discovery and description of seven New Zealand methane seep sites, an infaunal assemblage dominated by ampharetid polychaetes was found in association with high seabed methane emission. This ampharetid-bed assemblage had a mean density of 57,000 ± 7800 macrofaunal individuals m⁻² and a maximum wet biomass of 274 g...

Lack of Neuromuscular Origins of Adaptation After a Long-Term Stretching Program

Creator:: Hayes, Bradley T., Harter, Rod A., Widrick, Jeffrey J., Williams, Daniel P., Hoffman, Mark A., and Hicks-Little, Charlie A.
Abstract:: Context: Static stretching is commonly used during the treatment and rehabilitation of orthopedic injuries to increase joint range of motion (ROM) and muscle flexibility. Understanding the physiological adaptations that occur in the neuromuscular system as a result of long-term stretching may provide insight into the mechanisms responsible for changes in...

Bomb-produced radiocarbon validation of growth-increment crossdating allows marine paleoclimate reconstruction

Creator:: Kastelle, Craig R., Helser, Thomas E., Black, Bryan A., Stuckey, Matthew J., Gillespie, Darlene C., McArthur, Judy, Little, Diana, Charles, Karen D., and Khan, Reziah S.
Abstract:: The bivalve Pacific geoduck (Panopea generosa) has been used in the eastern North Pacific Ocean to create proxies for environmental factors such as temperature and oceanographic conditions. This type of research depends upon accurate age determination of Pacific geoducks, which historically was based on shell growth-increment counts. A recent study...

Identifying Potential Mechanisms Enabling Acidophily in the Ammonia-Oxidizing Archaeon "Candidatus Nitrosotalea devanaterra"

Creator:: Lehtovirta-Morley, Laura E., Sayavedra-Soto, Luis A., Gallois, Nicolas, Schouten, Stefan, Stein, Lisa Y., Prosser, James I., and Nicol, Graeme W.
Abstract:: Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has...

Ontologies as Integrative Tools for Plant Science

Creator:: Walls, Ramona L., Athreya, Balaji, Cooper, Laurel, Elser, Justin, Gandolfo, Maria A., Jaiswal, Pankaj, Mungall, Christopher J., Preece, Justin, Rensing, Stefan, Smith, Barry, and Stevenson, Dennis W.
Abstract:: Premise of the study: Bio-ontologies are essential tools for accessing and analyzing the rapidly growing pool of plant genomic and phenomic data. Ontologies provide structured vocabularies to support consistent aggregation of data and a semantic framework for automated analyses and reasoning. They are a key component of the semantic web....

Toward autonomous measurements of photosynthetic electron transport rates: An evaluation of active fluorescence-based measurements of photochemistry

Creator:: Silsbe, Greg M., Oxborough, Kevin, Suggett, David J., Forster, Rodney M., Ihnken, Sven, Komárek, Ondřej, Lawrenz, Evelyn, Prášil, Ondřej, Röttgers, Rüdiger, Šicner, Michal, Simis, Stefan G. H., Van Dijk, Mark A., and Kromkamp, Jacco C.
Abstract:: This study presents a methods evaluation and intercalibration of active fluorescence-based measurements of the quantum yield (ϕ'ₚₛᵢᵢ) and absorption coefficient (aₚₛᵢᵢ) of photosystem II (PSII) photochemistry. Measurements of ϕ'ₚₛᵢᵢ, aₚₛᵢᵢ, and irradiance (E) can be scaled to derive photosynthetic electron transport rates (Pₑ), the process that fuels phytoplankton carbon fixation...

Abstract:: The Plant Ontology (PO;http://www.plantontology.org/" is a publicly available, collaborative effort to develop and maintain a controlled, structured vocabulary ('ontology') of terms to describe plant anatomy, morphology and the stages of plant development. The goals of the PO are to link (annotate) gene expression and phenotype data to plant structures and...
