That hummingbird-pollinated plants predominantly have red flowers has been known for decades, but well-investigated research studies are still rare. Preference tests have shown that hummingbirds do not have an innate preference for red colours. In addition, hummingbirds do not depend solely upon red flowers, because white-flowered hummingbird-pollinated plants are also common and temporarily ab...

'The great appear great, because we are on our knees. Let us rise!,' wrote Larkin. Jean Faugier ( 1 ) described the 'tall poppy syndrome' and spoke of 'bold, nonconformist', brightly- coloured flowers being chopped down mercilessly by farmers just because they were different and stood above the rest in the wheatfields.

Suicide is a serious social and health problem in Korea [1]. According to a 2005 report by the Organization for Economic Cooperation and Development [2], Korea had the highest suicide rate with nearly 30 deaths per 100,000 population. Many studies have found that suicidal ideation and attempts among lesbians, gay men, and bisexual persons are higher than among heterosexual individuals (or gener...

This is an experimental review essay responding to Michael Marder’s Plant-Thinking: A Philosophy of Vegetal Life (New York: Columbia University Press, 2013). The essay departs from the ordinary structure of comparing three books on a similar theme. Instead three of Marder’s concepts, plant “nourishment,” “desire” and “language” are explored through readings of Gabrielle de Vietri’s installation...

Australian crab spiders Thomisus spectabilis manipulate visual flower signals to lure introduced Apis mellifera. We gave Australian native bees, Austroplebia australis, the choice between two white daisies, Chrysanthemum frutescens, one of them occupied by a crab spider. The colour contrast between flowers and spiders affected the behaviour of native bees. Native bees approached spider-occupied...

In the current efforts to account for the failings of American education, the searchlight of attention has been turned to the quality of teaching. The implication seems to be that teaching, among all the variables that affect colleges and schools, is most susceptible to management and repair. The themes recur in state after state: career ladders, merit pay, teacher testing, job analysis, effect...

In plants whose flowers develop in a sequence, different flowers may exhibit temporal variation in pollen donation and receipt such that the fitness contributions through male and female functions can vary among flowers. Dichogamy, or directional pollinator movements within inflorescences, can create situations where flowers in different stages in the sequence may differ in the numbers of flowe...

A novel rapid, simple and solvent-free method was developed for determination of the volatile compounds from the flowers of Chimonanthus praecox Link using headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS). The SPME conditions were firstly optimized and applied to sampling of the volatile compounds emitted from living Chimonanthus praecox L. flower...

In this paper, we conduct a systematic review on the topic of entrepreneurial passion. We summarize empirical findings studies based four major conceptualizations passion: passion for work, dualistic model passion, and perceived Moreover, analyze 63 published papers in literature identify potential research opportunities area. First, relationship between firm performance needs further examinati...

BACKGROUND AND AIMS Andromonoecy, as a breeding system, has generated a considerable body of theory in terms of sexual selection, but extended records comparing the performance of pollen grains from staminate versus hermaphrodite flowers are still sparse. The objective in this study was to elucidate the role of staminate flowers in the andromonoecious breeding system of olive (Olea europaea). ...
