Creator:: Shorey, Lyndsey E., Hagman, Amanda M., Williams, David E., Ho, Emily, Dashwood, Roderick H., and Benninghoff, Abby D.
Abstract:: Certain bioactive food components, including indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM) from cruciferous vegetables, have been shown to target cellular pathways regulating carcinogenesis. Previously, our laboratory showed that dietary I3C is an effective transplacental chemopreventive agent in a dibenzo[def,p]chrysene (DBC)-dependent model of murine T-cell lymphoblastic lymphoma.

Key areas for conserving United States’ biodiversity likely threatened by future land use change

Creator:: Martinuzzi, S., Radeloff, V. C., Higgins, J. V., Helmers, D. P., Plantinga, A. J., and Lewis, D. J.
Abstract:: A major challenge for biodiversity conservation is to mitigate the effects of future environmental change, such as land use, in important areas for biodiversity conservation. In the United States, recent conservation efforts by The Nature Conservancy and partners have identified and mapped the nation's Areas of Biodiversity Significance (ABS), representing...

Regional variation in stand structure and development in forests of Oregon, Washington, and inland Northern California

Creator:: Reilly, Matthew J. and Spies, Thomas A.
Abstract:: Despite its importance to biodiversity and ecosystem function, patterns and drivers of regional scale variation in forest structure and development are poorly understood. We characterize structural variation, create a hierarchical classification of forest structure, and develop an empirically based framework for conceptualizing structural development from 11,091 plots across 25 million...

Isotopic constraints on the pre-industrial oceanic nitrogen budget

Creator:: Somes, C. J., Oschlies, A., and Schmittner, A.
Abstract:: The size of the bioavailable (i.e., “fixed”) nitrogen inventory in the ocean influences global marine productivity and the biological carbon pump. Despite its importance, the pre-industrial rates for the major source and sink terms of the oceanic fixed nitrogen budget, N₂ fixation and denitrification, respectively, are not well known. These...

Effect of age-based and environment-based cues on reproductive investment in Gambusia affinis

Creator:: Billman, Eric J. and Belk, Mark C.
Abstract:: We examined the multivariate life-history trajectories of age 0 and age 1 female Gambusia affinis to determine relative effects of age-based and environment-based cues on reproductive investment. Age 0 females decreased reproductive investment prior to the onset of fall and winter months, while age 1 females increased reproductive investment as...

Complex network theory, streamflow, and hydrometric monitoring system design

Creator:: Halverson, M. J. and Fleming, S. W.
Abstract:: Network theory is applied to an array of streamflow gauges located in the Coast Mountains of British Columbia (BC) and Yukon, Canada. The goal of the analysis is to assess whether insights from this branch of mathematical graph theory can be meaningfully applied to hydrometric data, and, more specifically, whether...

Estimating the absolute wealth of households

Creator:: Hruschka, Daniel J., Gerkey, Drew, and Hadley, Craig
Abstract:: The estimation of the economic status of individuals and their households is central to much work in epidemiology and the social sciences. Wealth is a key determinant of health and social achievement and an indicator of well-being in its own right. For this reason, the development and testing of novel...

Abstract:: The reliable simulation of gross primary productivity (GPP) at various spatial and temporal scales is of significance to quantifying the net exchange of carbon between terrestrial ecosystems and the atmosphere. This study aimed to verify the ability of a nonlinear two-leaf model (TL-LUEn), a linear two-leaf model (TL-LUE), and a...

Evaluating the Return in Ecosystem Services from Investment in Public Land Acquisitions

Creator:: Kovacs, Kent, Polasky, Stephen, Nelson, Erik, Keeler, Bonnie L., Pennington, Derric, Plantinga, Andrew J., and Taff, Steven J.
Abstract:: We evaluate the return on investment (ROI) from public land conservation in the state of Minnesota, USA. We use a spatially-explicit modeling tool, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), to estimate how changes in land use and land cover (LULC), including public land acquisitions for conservation, influence...

Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea

Creator:: Benoit-Bird, Kelly J., McIntosh, Neal E., and Heppell, Scott A.
Abstract:: We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye pollock around the Pribilof Islands in the southeastern Bering Sea in 2008 and 2009 was...

Calcium carbonate production response to future ocean warming and acidification

Creator:: Pinsonneault, A. J., Matthews, H. D., Galbraith, E. D., and Schmittner, A.
Abstract:: Anthropogenic carbon dioxide (CO₂) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms, and thereby modifying the oceanic carbon and alkalinity cycles. However, the responses of pelagic calcifying organisms to acidification vary widely between species, contributing uncertainty to predictions of atmospheric CO₂ and the resulting climate change. At...
