Between January and December 1996, three times a month, blooming plants were sampled. Floral traits such as size, shape, symmetry, sexuality, anther dehiscence, and colour; floral rewards and flowering period were recorded for each species. Restinga, a sand dune scrub is the vegetation type, formed mainly by shrubs and subshrubs. Ninety-seven plant species were observed, Fabaceae was the richest family in number of species. Bees visited 66 species but concentrated their visits in 12 species (79.4% of total of individuals). Waltheria cinerescens St. Hilaire and Byrsonima microphylla A. Juss. were the most abundant species in the area. Floral resources were available for the bees during the whole year but the number of flowers was greater at the low rainfall season. In general, flowers remained open during the whole day; most of them were monoclinous (89% of species), small, tubular, pink-purple (32%) and cream (31%), actinomorphic (63%) and arranged in inflorescences. Most of the species are mellitophilous (85%), it means that bees are probably the main pollen vector in this ecosystem. Key words-Apoidea, bee plants, restinga, sand dunes RESUMO-(A flora apícola de uma área restrita de dunas litorâneas, Abaeté, Salvador, Bahia). A comunidade de plantas visitadas por abelhas foi estudada em um fragmento de 8,2 ha na Área de Proteção Ambiental das Lagoas e Dunas de Abaeté, Salvador, Bahia (12º56' S e 38º21' W). Entre janeiro e dezembro de 1996, três vezes ao mês, as plantas floridas eram amostradas, registrando-se para cada espécie o período de floração, hábito e características florais como: cor, forma, sexualidade, simetria, deiscência das anteras e recurso oferecido ao visitante. O tipo de vegetação local é a restinga, composta principalmente por arbustos e subarbustos. Foram observadas 97 espécies vegetais e a família Fabaceae foi a mais rica em número de espécies. Das espécies observadas, 66 foram visitadas por abelhas, sendo que 12 delas foram predominantemente visitadas (79,4% do total de indivíduos). Waltheria cinerescens St. Hilaire e Byrsonima microphylla A. Juss. foram as espécies mais abundantes. Os recursos florais estiveram disponíveis ao longo de todo o ano, havendo maior produção de flores nos meses de menor precipitação. A maioria das flores esteve aberta durante todo o dia. Predominaram flores actinomorfas (63%), monóclinas (89%), pequenas, tubulares e reunidas em inflorescências, cujas cores mais freqüentes são lilás (32%) e creme (31%). A maioria era melitófila (85%), significando que as abelhas são, provavelmente, os principais responsáveis pela reprodução sexual das espécies vegetais nessas dunas.

These part-time jobs have begun to dominate my days, and I'm finding it harder and harder to find time to write and to manage my company's affairs. Worse, I know that by taking on these tasks, other folks are being put out of a job. Why am I doing this? Let me explain. It's been a slow evolution. One day, back in the early 1970s, I drove up to the local Exxon, and Joe, the gas station attendant, was gone. I missed him almost right away-his smiling face beaming through the windshield as he sprayed and squeegeed it before diving under the hood to check the oil level. "A buck-fifty!" I'd say, and he'd politely pump in four gallons to keep the gas price within the limit of the cash I had in my purse. It seems like forever now, but I've pumped my own gas ever since. As businesses tightened their belts, they discovered that consumers would take on many semi-invisible jobs: bagging groceries, pumping gas, driving kids to and from school, busing tables-the list goes on.

A mere 73 seconds into its flight, Challenger broke apart in a fiery explosion, killing all seven astronauts on board. America and the world entered a period of shock and mourning. Allan J. McDonald felt that shock profoundly. He had recommended that NASA (the National Aeronautics and Space Administration) delay the launch because of uncharacteristically cold weather in Florida's Cape Canaveral, arguing that the O-rings designed to seal off the shuttle's volatile propellants were dangerously unreliable at temperatures below 40°F and had been tested only at 53° and above. The thermometer hovered around 36° that fateful morning. McDonald headed the Solid Rocket Motor Project for Morton Thiokol Inc., the manufacturer of the O-rings. He was dumbfounded when his recommendation was not heeded. He understood the public relations ramifications of another launch postponement; weather and technical problems already had delayed the launch by six days. And he understood Thiokol's desire to give NASA what it wanted (McDonald & Hansen 2012).
