Acorn Contribution to Mammalian Energetics
Acorns are a highly nutritious food source for many mammal species including white-tailed deer (Odocoileus virginianus), white-footed mice (Peromyscus leucopus), eastern gray squirrels (Sciurus carolinenis), and fox squirrels (S. niger). Oak trees (genus (Quercus) produce variable amounts of acorn …

Population Dynamics and Dispersal Coalitions in the Cooperatively Breeding Acorn Woodpecker
… in a population of cooperatively breeding acorn woodpeckers in central California, USA. Using a 34-year dataset on occupancy and abundance, I determined that increases in abundance were determined by dispersal to new locations. This resulted in increased occupancy, rather than increases in …

Improving peer review with ACORN : Ant Colony Optimization algorithm for Reviewer's Network
Peer review, our current system for determining which papers to accept and which to reject by journals and conferences, has limitations that impair the quality of scientific communication. Under the current system, reviewers have only a limited amount of time to devote to evaluating papers and each …

Aphrodite as Acorn: Method and Message in the Cantos of Ezra Pound
… I will discuss Hugh Kenner's metaphor of the acorn, and undertake, in the third part of the paper, to show how this metaphor is related to the method of Pound's creation of Aphrodite. My purpose is finally to be able to understand how the appearance of Aphrodite relates to the message of The …

Physiological Response of the Giant Acorn Barnacle, Balanus nubilus, to Air Exposure
<p>The giant acorn barnacle, <em>Balanus nubilus</em>, is a resident of the subtidal and low intertidal rocky shoreline on the Pacific Coast of North America (Alaska to Baja California). <em>B. nubilus</em>is notable for having the largest muscle fibers in the animal kingdom; fiber diameters that …

Acorn Caching and Consumption of Weevil-infested Nuts: Possible Means of Tannin Circumvention for the Blue Jay
… other Fagaceous trees in eastern North America. Acorns comprise much of the jay diet (Beal 1896), especially during the autumn months when jays may consume or cache a significant portion of an acorn crop. However, jays do not appear to possess physiological adaptations for countering the …

Effect of Oxygen-Limiting Tidal Conditions on Muscle Metabolism and Structure in the Giant Acorn Barnacle, Balanus nubilus
… kingdom, with fiber diameters in the giant acorn barnacle (<em>Balanus nubilus</em>) exceeding 3 mm. Sessile animals with extreme muscle sizes and that live in the hypoxia-inducing intertidal zone – like <em>B. nubilus</em> – represent ideal models for probing the effects of oxygen …

Effects of gypsy moth defoliation on acorn production and viability, litterfall, and litter layer depth and biomass in north-central Virginia and western Maryland
The effects of gypsy moth defoliation on acorn production (the seed source for oak regeneration), and the forest floor regeneration environment were investigated. Parameters measured included: acorn quantity, weight, development, and viability; litterfall; and forest floor depth and biomass. …

Southwest Cooking Oil: Acorn Oil from Native Oak Species Q. Macrocarpa, Q. Shumardii, and Q. Polymorpha Acorns as a Potential High-End Cooking Oil
The oil produced from acorns (Quercus) has been consumed by native peoples for hundreds of years. It is a nutritious cooking oil comparable to olive oil. Acorn oil is not currently produced on a market scale. This project attempted to extract oil from three native Texas species; however, due to …

Effects of tannins on protein digestibility and detoxification activity in gray squirrels (Sciurus carolinensis)
Captive gray squirrels were fed acorns or diets containing commercial tannins to determine the effects of tannins on digestion and detoxification (glucuronidation) activity. In the Acorn experiment, Northern red oak acorns (Quercus rubra), white oak acorns (Q. alba), or rat chow were fed to …

Indirect effects between deer, mice, and the gypsy moth in a forest community
… abundances, which likely resulted from a large acorn mast the previous year, may be obscuring indirect effects that would be detected at lower mouse abundances.

Response of black bears to gypsy moth infestation in Shenandoah National Park, Virginia
… Infestation resulted in a 99% reduction in acorn production in defoliated stands. Maximum daily temperatures 0.5 m above the ground in defoliated stands averaged 4.7 ± 0.3 C, 4.3 ± 0.4 C, and 2.5 ± 0.3 C warmer (P < 0.01) than in nondefoliated stands during peak defoliation, refoliation, and …

A KANTIAN ELABORATION OF BRAITHWAITE'S RESTORATIVE JUSTICE: DISPELLING ILLUSIONS

No-tillage squash production on agricultural soil and minesoil
… mulch on agricultural soil increased marketable acorn squash (Curcurbita pepo L. 'Table Ace’) yield by 29% as compared to a conventional tillage practice. These yield differences are attributed to increased plant population and possible improved water infiltration in no-tillage systems. A …

Predicting forest cover types in Southwestern Virginia using topographic information
… differences were not significant. Estimates of acorn production were highest in old stands containing a high percentage of oaks. Oak stands on moist sites appeared to have higher estimated mast yields than those on dry sites, but differences were not significant. Based on the results of these …

Development of floral primordia and prediction of flowering in white oak (Quercus alba L.)
… and flower crop variability as they relate to acorn crop variability. The first part traced the ontogeny of staminate and pistillate primordia of white oak (Quercus alba L.). It was found that staminate inflorescences are initiated in late spring and staminate flowers are structurally mature …
