New research has identified flavonols as a class of phenolic compounds which can be manipulated by both vineyard and winery practices. These phenolic compounds are key quality components of wine, affecting sensory characteristics, wine color, and wine stability. Modification of the phenolic precursors in grapes occur during fermentation and aging...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...
Water movement, from forest soil to streams, has traditionally been modeled by translatory flow. A hypothesis was presented by Brooks et al. (2010) suggesting that, in addition to translatory flow, there exists an immobile pool of water trapped in small pores with low matric potential. Comparisons of water stable isotope...
The study was conducted in an organic trailing blackberry (Rubus L. subgenus Rubus, Watson) planting established at the North Willamette Research and Extension Center in Aurora, OR on 26 May 2010. Three weed management systems were compared for 'Marion' and 'Black Diamond': 1) non-weeded; 2) hand-hoed two to three times...
After the commercial exploitation of humpback whales (Megaptera Novaeangliae) ceased, population trends in the North Pacific increased with the implementation of federal protective legislation. The recovery of the population prompted the National Oceanic and Atmospheric Administration to divide the population into 14 Distinct Population Segments (DPSs) based on discrete geographic...
The ability of ovine endometrium incubated in vitro with
estradiol -17(3 to synthesize a specific induced protein (IP) was
studied. Endometrium from cycling, pregnant and ovariectomized
ewes was used.
Twelve ewes were allotted in equal numbers to be sacrificed on
days 0 (estrus), 3, 6, or 10 of the estrous...
South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a...
I monitored demography, movement, and reproductive behavior of gray-tailed voles, Microtus canicaudus, in experimental habitat patches with and without corridors. I tested the hypotheses that reproductive rate, juvenile recruitment, and population size and growth rate would be affected negatively by immigrants that were introduced to resident groups (+ male and...
