Yellow nutsedge is an important weed problem in the furrow irrigated fields in the Treasure Valley of eastern Oregon and southwestern Idaho. Field studies were conducted in 2008 and 2009 to evaluate the effect of PPI S-metolachlor or EPTC followed by POST halosulfuron and dicamba plus glyphosate or glyphosate alone...
Greenhouse studies were conducted to evaluate the influence of selected adjuvants on
glyphosate efficacy on yellow nutsedge and tuber production. Glyphosate was applied
at 0, 0.25, 0.43, 0.87, 1.26 (1x rate), and 1.74 kg ae ha⁻¹ 31 d after yellow nutsedge
was planted. Each rate was mixed with one of...
Saccharomyces cerevisiae contains three NAD⁺/NADH kinases, one of which is localized in
mitochondria and phosphorylates NADH in preference to NAD⁺. Strand et al (Euk. Cell
2:809 (2003)) reported that a yeast mutation in POS5, which encodes the mitochondrial
NADH kinase, is a mutator, specific for mitochondrial genes. Because of the...
We report here on recent developments and advances in pore-scale x-ray tomographic imaging of subsurface porous media. Our particular focus is on immiscible multi-phase fluid flow, i.e., the displacement of one immiscible fluid by another inside a porous material, which is of central importance to many natural and engineered processes....
A workshop was held in Santa Barbara, California, associated with assessing the populations of nekton animals such as squids, shrimps and fishes. Sessions four major methods of assessing nekton populations:
(1) Net collections
(2) Acoustics
(3) Egg/larval surveys
(4) Visual methods, remote sensing and feeding habit studies
An attempt was...
1. Ecologists, outdoor professionals and the public work and play in lands with complex histories. Part of decolonizing our professional and recreational practices is to expose settler colonial biases and recognize the histories of colonized lands and the peoples who have stewarded these lands for millennia prior to colonization.
2....
We investigated how large carnivores, herbivores, and plants may be linked to the maintenance of native species biodiversity through trophic
cascades. The extirpation of wolves (Canis lupus) from Yellowstone National Park in the mid-1920s and their reintroduction in 1995 provided the
opportunity to examine the cascading effects of carnivore–herbivore interactions...
• A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees.
• Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...
Body size is known to correlate with many aspects of life history in birds, and this knowledge can be used to manage and conserve bird species. However, few studies have compared the wintering ecology of sympatric subspecies that vary significantly in body size. We used radiotelemetry to examine the relationship...
Diets of juvenile coho Oncorhynchus kisutch and Chinook O. tshawytscha salmon
are made up primarily of winter-spawning fish taxa in the late-larval and early juvenile stages that
are undersampled in plankton and larger trawl nets. Although we have no direct measure of the
availability of fish prey important to juvenile...
