Mercury (Hg) contamination is a global conservation threat to freshwater ecosystems, detected in even the protected lakes of Olympic National Park (Washington, USA). Although considered some of the most remote and pristine US ecosystems, these lakes are currently subject to multiple environmental stressors, including climate change and fish introductions; adding...
In situ attenuation (488 and 660 nm), absorption (488, 676, and 750 nm), backscattering (at 488 nm), and
stimulated fluorescence were determined as functions of depth in oceanic and coastal waters off Oregon,
using both commercial instruments and recently developed prototypes. The inability to perfectly constrain
scattered light in these...
The 1995 FAO Code of Conduct for Responsible Fisheries provides a policy framework for sustainable fisheries management. Many FAO Members indicate that the lack of information continues to constrain the full and effective implementation of the Code. This Circular seeks to address a range of information issues required to support...
Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...
The loss of all deuterium labels from previous feedings of [2-²H]-,
[3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy
of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the
biosynthesis of the streptolidine portion of streptothricin F (la).
In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]-
arginine (32) was...
This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and...
Research has shown that African Americans/Blacks, especially those with low socioeconomic status, acknowledge athletics as an avenue for upward mobility (Coakley, 2011). Although the chances of becoming a professional athlete might seem unachievable through sports, athletes develop tangible and intangible abilities that transfer and are useful in the years following...
