The accessions used to create the Snap Bean Diversity Panel (SnAP) were 378 snap bean cultivars and germplasm lines selected from North American and European germplasm. This panel supplements the 150 member Bean CAP snap bean diversity panel (SBDP) with an additional 228 snap bean accessions. The Bean CAP SBDP...
The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...
Since its introduction in the early 1990s, the quick growth of the World Wide Web
(WWW) traffic raises the question of whether past Local Area Network (LAN) packet
traces still reflect the current situation or whether they have become obsolete. For this
thesis, several LAN packet traces were obtained by...
This dataset includes species richness of native plants, pollinators and birds as well as 13 proxies for ecosystem services representing timber production, culturally-valued plants and animals, and regulating services tied to forest productivity. The data were collected from an experiment conducted in the Oregon Coast Range USA that sought to...
By inverting EarthScope long-period magnetotelluric (MT) data from the southeastern United States (SEUS), we obtain electrical conductivity images that provides key insights into the geodynamics of this region. Significantly, we resolve a highly electrically resistive block that extends to mantle depths beneath the modern Piedmont and Coastal Plain physiographic provinces....
We sampled vegetation, bryophytes, lichens, environment, and stand dynamics in 56 plots in the Swan Valley, Montana in 1975-1978. The data include complete inventory of trees in 375 m2 plots, with whole-plot ocular estimates of plant cover by species, transect sampling of the ground layer bryophytes and lichens with microplots,...
Knowledge of nutrient pathways and their resulting ecological interactions can alleviate numerous environmental problems associated with nutrient increases in both natural and managed systems. Although not unique, coastal systems are particularly prone to complex ecological interactions resulting from nutrient inputs from both the land and sea. Nutrient inputs to coastal...
A change in climate is known to affect seasonal timing (phenology) of the life stages of poikilothermic organisms whose development depends on temperature. Less understood is the potential for even greater disruption to the life cycle when a phenology shift exposes photoperiod-sensitive life stages to new day lengths. We present...
The integration of satellite image data with forest inventory plot data is a popular approach for mapping forest vegetation over large regions. Several methodological choices regarding spatial scale, mostly related to spatial resolution or grain, can profoundly influence forest maps developed from plot and imagery data. Yet often the consequences...
Ecological network models and analyses are recognized as valuable tools for understanding the dynamics and resiliency of
ecosystems, and for informing ecosystem-based approaches to management. However, few databases exist that can
provide the life history, demographic and species interaction information necessary to parameterize ecological network
models. Faced with the difficulty...
