Population viability analyses provide a quantitative approach that seeks to predict the possible future status of a species of interest under different scenarios and, therefore, can be important components of large-scale species’ conservation programs. We created a model and simulated range-wide population and breeding habitat dynamics for an endangered woodland...
Communities throughout the world have grappled with the positive and negative impacts of tourism for years. Oregon State University’s (OSU) Sustainable Tourism Lab was created in 2021 to support such global destinations and help them pursue a sustainable path – inclusive of economic, community, and environmental perspectives. Our first step...
Regulation of cell division and expansion are critical for plant development. The mechanisms that control these processes are not clearly understood in higher plants. In other eukaryotic models it has been shown that the highly conserved Rho family GTPases play a crucial role in these mechanisms. One distinct subset of...
Coastal Douglas-fir (Psuedotsuga menziesii (Mirb.) Franco) 1 + 1 seedlings were fertilized with two types of fertilizers (NB4NO3+K2SO4 and (NH.4)2 SO4+KC1) at four rates (0, 80, 160, 320 kg N and K/ha) split over 3 application dates (September 19, October 13, November 1, 1996). By January 10, total Kjeldahl nitrogen...
The Elliott State Forest, created in 1930 and now the Elliott State Research Forest, is 33,700 ha of rainforest located 10–32 km inland from North America's Pacific Ocean coast. Its location in the central part of the Oregon Coast Range (Oregon, United States) places the Elliott Forest at lower elevations...
Discrete aqueous metal oxide polyionic clusters that include aluminum polycations, transition-metal polyoxometalates, and the actinyl peroxide clusters have captivated the interest of scientists in the realm of both their fundamental and applied chemistries. Yet the counterions for these polycations or polyanions are often ignored, even though they are imperative for...
Understanding fundamental uranyl polyoxometalate
(POM) chemistry in solution and the solid state is
the first step to defining its future role in the development
of new actinide materials and separation processes
that are vital to every step of the nuclear fuel cycle. Many
solid-state geometries of uranyl POMs have been...

Solid-state ¹H magic-angle spinning (MAS) NMR was used to investigate local proton environments in anhydrous [UO₂(OH)₂] (α-UOH) and hydrated uranyl hydroxide [(UO₂)₄O(OH₆ 6·5H₂O (metaschoepite). For the metaschoepite material, proton resonances of the μ₂-OH hydroxyl and interlayer waters were resolved, with two-dimensional (2D) double-quantum (DQ) ¹H–¹H NMR correlation experiments revealing strong...
