Phenotypic Plasticity of the Hydrasperman Seed Fern Tetrastichia bupatides Gordon (Lyginopteridaceae)

Creator:: Dunn, Michael T. and Rothwell, Gar W.
Abstract:: Fifty-nine stems of Tetrastichia bupatides, numerous frond segments, and roots from Oxroad Bay, Scotland, have recently been analyzed. They reveal that many characters originally used to describe this species exhibit a wider range of variation than previously suspected. These data suggest that ribs of the protostele are most commonly four...

Coupling snowpack and groundwater dynamics to interpret historical streamflow trends in the western United States

Creator:: Safeeq, Mohammad, Grant, Gordon E., Lewis, Sarah L., and Tague, Christina. L.
Abstract:: A key challenge for resource and land managers is predicting the consequences of climate warming on streamflow and water resources. During the last century in the western United States, significant reductions in snowpack and earlier snowmelt have led to an increase in the fraction of annual streamflow during winter and...

Intraseasonal Sea Surface Temperature Variability across the Indonesian Seas

Creator:: Napitu, Asmi M., Gordon, Arnold L., and Pujiana, Kandaga
Abstract:: Sea surface temperature (SST) variability at intraseasonal time scales across the Indonesian Seas during January 1998–mid-2012 is examined. The intraseasonal variability is most energetic in the Banda and Timor Seas, with a standard deviation of 0.4°–0.5°C, representing 55%–60% of total nonseasonal SST variance. A slab ocean model demonstrates that intraseasonal...

Predicting landscape sensitivity to present and future floods in the Pacific Northwest, USA

Creator:: Safeeq, Mohammad, Grant, Gordon E., Lewis, Sarah L., and Staab, Brian
Abstract:: Floods are the most frequent natural disaster, causing more loss of life and property than any other in the USA. Floods also strongly influence the structure and function of watersheds, stream channels, and aquatic ecosystems. The Pacific Northwest is particularly vulnerable to climatically driven changes in flood frequency and magnitude,...

Creator:: Flitcroft, Rebecca L., Burnett, Kelly M., Reeves, Gordon H., and Ganio, Lisa M.
Abstract:: 1. Aquatic ecologists are working to develop theory and techniques for analysis of dynamic stream processes and communities of organisms. Such work is critical for the development of conservation plans that are relevant at the scale of entire ecosystems. The stream network is the foundation upon which stream systems are...

Catch Shares, the Theory of Cooperative Games and the Spirit of Elinor Ostrom: A Research Agenda

Creator:: Munro, Gordon, Sumaila, U. Rashid, and Turris, Bruce
Abstract:: This paper puts forth the proposition that all catch share schemes should be analysed primarily through the lens of cooperative game theory, which has now been developed to an advanced degree in the analysis of international fisheries management. If the fishers in a catch share scheme are playing cooperatively, the...

Acceptance, Acceptability, and Trust for Sagebrush Restoration Options in the Great Basin: A Longitudinal Perspective

Creator:: Gordon, Ryan, Brunson, Mark W., and Shindler, Bruce
Abstract:: In surveys of residents in three urban and three rural locations in the Great Basin we examined the social acceptability of six management practices showing promise for restoring sagebrush-dominated rangelands. Unlike most studies of range management perceptions that have relied on single measurements, we used longitudinal data from a questionnaire...

Demographic and phenotypic responses of juvenile steelhead trout to spatial predictability of food resources

Creator:: Sloat, Matthew R. and Reeves, Gordon H.
Abstract:: We manipulated food inputs among patches within experimental streams to determine how variation in foraging behavior influenced demographic and phenotypic responses of juvenile steelhead trout (Oncorhynchus mykiss) to the spatial predictability of food resources. Demographic responses included compensatory adjustments in fish abundance, mean fish size, and size inequality. These responses...

Individual condition, standard metabolic rate, and rearing temperature influence steelhead and rainbow trout (Oncorhynchus mykiss) life histories

Creator:: Sloat, Matthew R. and Reeves, Gordon H.
Abstract:: We reared juvenile Oncorhychus mykiss with low and high standard metabolic rates (SMR) under alternative thermal regimes to determine how these proximate factors influence life histories in a partially migratory salmonid fish. High SMR significantly decreased rates of freshwater maturation and increased rates of smoltification in females, but not males,...

Effects of the Mycoparasite Sphaerellopsis filum on Overwintering Survival of Stem Rust in Perennial Ryegrass

Creator:: Gordon, T. C. and Pfender, W. F.
Abstract:: Sphaerellopsis filum is a mycoparasite of Puccinia graminis subsp. graminicola, a rust fungus that causes widespread crop damage on perennial ryegrass grown for seed. In observations taken over the winter months, S. filum was found naturally colonizing 2% of P. graminis subsp. graminicola uredinia on first-year plantings and 25% of...

High frequency transformation of cottonwoods (genus Populus) by Agrobacterium rhizogene

Creator:: Han, Kyung-Hwan, Gordon, Milton P., and Strauss, Steven H.
Abstract:: Many species of Populus, particularly cottonwoods of sections Aigeiros and Tacamahaca, remain recalcitrant to genetic transformation. We demonstrate that transgenic trees can be readily produced in several poplar genotypes using wild-type Agrobacterium rhizogenes. Hairy roots were produced in a variety of clones that included Populus trichocarpa Torr. & A. Gray,...

Separating the wheat from the chaff: mitigating the effects of noise in a plastome phylogenomic data set from Pinus L. (Pinaceae)

Creator:: Parks, Matthew, Cronn, Richard, and Liston, Aaron
Abstract:: Background: Through next-generation sequencing, the amount of sequence data potentially available for phylogenetic analyses has increased exponentially in recent years. Simultaneously, the risk of incorporating ‘noisy’ data with misleading phylogenetic signal has also increased, and may disproportionately influence the topology of weakly supported nodes and lineages featuring rapid radiations and/or...

Thinning and in-stream wood recruitment in riparian second growth forests in coastal Oregon and the use of buffers and tree tipping as mitigation

Creator:: Benda, Lee E., Litschert, S. E., Reeves, Gordon, and Pabst, Robert
Abstract:: Many aquatic habitats in coastal Oregon have been impacted by historic land use practices that led to losses of in-stream wood and associated degraded fish habitats. Many of these streams are now bordered by stands of dense second growth forests (30–80 years) that are incorporated into riparian buffer zones with...

Effects of wood on debris flow runout in small mountain watersheds

Creator:: Lancaster, Stephen T., Hayes, Shannon K., and Grant, Gordon E.
Abstract:: Debris flows have typically been viewed as two-phase mixtures of sediment and water, but in forested mountain landscapes, wood can represent a sizable fraction of total flow volume. The effects of this third phase on flow behavior are poorly understood. To evaluate whether wood can have a significant effect on...

Young Adult Outcomes Associated with Teen Pregnancy Among High-Risk Girls in an RCT of Multidimensional Treatment Foster Care

Creator:: Leve, Leslie D., Kerr, David C. R., and Harold, Gordon T.
Abstract:: Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group...

An observationally based constraint on the water-vapor feedback

Creator:: Gordon, N. D., Jonko, A. K., Forster, P. M., and Shell, K. M.
Abstract:: The increase in atmospheric concentrations of water vapor with global warming is a large positive feedback in the climate system. Thus, even relatively small errors in its magnitude can lead to large uncertainties in predicting climate response to anthropogenic forcing. This study incorporates observed variability of water vapor over 2002–2009...
