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...
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...
Nuclear waste is going nowhere, and neither is the debate over its disposal. The problem, growing every day, has proven intractable, with policymakers on one side, armed with daunting technical data, and the public on the other, declaring: not in my backyard. This timely volume offers a look past our...
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....
This paper presents the interim results of an ongoing research project funded by the 'Research Councils
UK' Rural Economy Land Use programme. The project has a multi-disciplinary perspective on the
potential production and marketing of tilapia as a niche product under a diversification strategy for UK
arable and dairy farmers;...
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...

Natural disasters are an increasingly costly and frequent occurrence globally and in the United States (IPCC, 2012; IPCC, 2014; Berlemann & Steinhardt, 2017). Discrete disaster events, such as coastal flooding, have been shown to be push factors in temporary and long-term migration (Black et al., 2013). Policy efforts to adapt...
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...
