An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area known as the Pilliga Scrub. Although the Pilliga Scrub is characterized by frequent and often large, intense wildfires, the site showed no sign of recent fire, which suggests this species is not a postfire morel.

The scientific study of Buddhist meditation has proceeded without much attention to Buddhist literature that details the range of psychological and physiological changes thought to occur during meditation. This paper presents reports of various meditation-induced light experiences derived from American Buddhist practitioners. The reports of light experiences are classified into two main types: discrete lightforms and patterned or diffuse lights.

Buddhist meditation practices have become a topic of widespread interest in both science and medicine. Traditional Buddhist formulations describe meditation as a state of relaxed alertness that must guard against both excessive hyperarousal (restlessness) and excessive hypoarousal (drowsiness, sleep). Modern applications of meditation have emphasized the hypoarousing and relaxing effects without as much emphasis on the arousing or alertness-promoting effects.

Staphylococcus aureus plays an important role in numerous human cases of food poisoning, soft tissue, and bone infections, as well as potentially lethal toxic shock. This common bacterium synthesizes various virulence factors that include staphylococcal enterotoxins (SEs). These protein toxins bind directly to major histocompatibility complex class II on antigen-presenting cells and specific Vβ regions of T-cell receptors, resulting in potentially life-threatening stimulation of the immune system.

We tested three predictions regarding the joint evolution of pollen performance and mating system. First, due to the potential for intense intrasexual competition in outcrossing populations, we predicted that outcrossers would produce faster-growing pollen than their selfing relatives. Second, if elevated competition promotes stronger selection on traits that improve pollen performance, then, among-plant variation in pollen performance would be lower in outcrossers than in selfers.

Breeding system of Macromeria viridiflora (Boraginaceae) and geographic variation in pollinator assemblages.

Am J Bot

November 2004

Warren Wilson College, CPO 6074, P.O. Box 9000, Asheville, North Carolina 28815-9000 USA.

This study explores the association between variation in pollinator type and flower size in Macromeria viridiflora (Boraginaceae) by studying the breeding system of the plant and the pollinator effectiveness of floral visitors. Studies were conducted at two sites where plants differ in flower size and floral visitors. Breeding system studies showed that while plants are self-compatible and occasionally produce seed autogamously, pollinators are important for reproductive success in the plants.

Stakeholder participation has become a key factor in the success of grassroots conservation and natural resource management programs. Yet the majority of program evaluations are conducted by external consultants for the purposes of accountability, rather than program improvement. Too often, systematic evaluations of conservation programs are not conducted at all.

Crystallization and preliminary X-ray crystallographic studies of recombinant human betaine-homocysteine S-methyltransferase.

Acta Crystallogr D Biol Crystallogr

March 2001

Department of Pharmaceutical and Biomedical Sciences, Wilson College of Pharmacy, University of Georgia, Athens 30602, USA.

Betaine-homocysteine S-methyltransferase (BHMT) catalyzes a reaction essential for regulation of methionine and homocysteine metabolism and the catabolism of choline in mammalian tissues. Human recombinant BHMT (MW = 45 kDa) has been crystallized by the hanging-drop vapor-diffusion method at 294 K using ethylene glycol as the precipitant. The crystals belong to the monoclinic space group C2, with unit-cell parameters a = 109.

Coming-out issues for adult lesbians: a group intervention.

Soc Work

November 1996

Social Work Program, Warren Wilson College, Asheville, NC 28815, USA.

This study investigated the effects of a 10-week, educational-experiential group intervention--the Coming Out Issues Group--designed to address issues pertinent to adult lesbians, including lesbian identity development, homophobia and heterosexism, religious concerns, career concerns, family issues, sexism and racism, and assertiveness skills development. The impact of the intervention was assessed using various instruments in four areas: (1) ego development, (2) lesbian identity development, (3) empowerment, and (4) disclosure. The results indicated modest gains in ego development and lesbian identity development and major gains in empowerment and disclosure.

The NK landscape model of adaptive evolution introduced by Kauffman & Levin (1987) is modified to simulate diversification of monophyletic lineages. Extinction probability is made a function of fitness, and speciation probability a function of the number of fitter one mutant neighbors, which is analogous to genetic potential. Dynamics of adaptive walks are measured as the total number of phenotypically defined species per generation.

Effect of Statistical Counting Errors on Wavelength Criteria for X-Ray Spectra.

J Res Natl Bur Stand A Phys Chem

January 1968

Physics Department, Wilson College, Chambersburg, Pa. 17201.

Various features of the spectral profile of an x-ray line can be measured with an uncertainty which is only a small fraction of the observed line width. With recent improvements in measurement techniques, statistical errors due to the random fluctuations of the intensities in counter recordings may become significant. The present study considers the effect of such errors on several features of the line profile which could be used for definition of its wavelength.
