Seminar paper from the year 2012 in the subject Biology - Zoology, grade: A, ( Atlantic International University ) (School of Science and Engineering), course: Master of Science (Applied Entomology), language: English, abstract: Bees evolved in specific areas of the world long ago, before they spread to become globally as they are today (Tables 1 and II), according to Kugonza (2009). As they spread, they became adapted to the local ecological conditions of the different areas, changing in morphology and behaviour to fit within the requirements of the ecosystem, giving rise to a wide bee biodiversity of bee species and races we see today. Bees are classified under Animal Kingdom, Phylum Arthropoda. They belong to Class Insecta, which is divided into 29 Orders. Bees belong to the order Hymenoptera, which has three Super families, namely: Apoidea (bees), Formicoidea (ants) and Vespoidea (wasps). There are around 30,000 named species of bees (Apoidea). Apoidea is further divided into several Families, namely Apidae (social bees), colletidae, Andrenidae, Halictidae, Melittidae, Megachilidae, and Anthophoridae. Most of the Families have solitary individuals: each female bee makes her own nest, lays a single egg and provides food for the single larva that develops. However, a high level of social development is shown by the species in Apidae where the individuals live together in a permanent, large colony, headed by a single egg-laying queen (BfD, 2003c). Apidae is composed of four genera: Apis (honeybees), Trigona and Melipona (stingless bees), and Bombus (bumble bees). According to MAAIF (2012a), the genus Apis is comprised of 5 main species of honey bees: Apis dorsata (the giant honey bee); Apis laboriosa (the darker giant honey bee); Apis florea (the little or dwarf honey bee); Apis cerana (formerly Apis indica), is the eastern hive honey bee; and Apis mellifera (western honey bee). These species have evolved and differentiated into more species and races of honey bees. Kugonza (2009) described 9 species of honey bees in the world, which Oldroyd and Wongsiri (2006) grouped under 3 subgenera: Micrapis (Apis florea and A. andreniformis), Megapis (A. dorsata and A. laboriosa) and Apis (A. cerana, recently recognized as separate races of A. nigrocinta, A. koschevnikovi and A. nuluensis, and A. mellifera). Dietz (1992), Hussein (2000) and Wikipedia (2012) described over 28 races of A. mellifera alone. Beekeeping started with honey bees (Apis species), a practice called Apiculture, although keeping of stingless bees, belonging to the genera Trigona and Melipona, a practice called Meliponiculture, has recently picked up [...]
For anyone who enjoys reading memoirs—or is thinking about writing one—this collection offers a master class from nine distinguished authors, including Annie Dillard, Frank McCourt, and others. The events, memories, and emotions of the past often resist the orderly structure of a book. Inventing the Truth offers wisdom from nine notable memoirists about their process (Ian Frazier searched through generations of family papers to understand his parents' lives), the hurdles they faced (Annie Dillard tackles the central dilemma of memoir: what to put in and what to leave out), and the unexpected joys of bringing their pasts to the page. Featured authors include Russell Baker on Growing Up; Jill Ker Conway on The Road from Coorain; Annie Dillard on An American Childhood; Ian Frazier on Family; Henry Louis Gates Jr. on Colored People; Alfred Kazin on A Walker in the City; Frank McCourt on Angela's Ashes; Toni Morrison on Beloved; and Eileen Simpson on Poets in Their Youth.
Did you grow up thinking math is boring? It’s time to reconsider. This book will teach you everything you ever wondered about numbers—and more. How and why did human beings first start using numbers at the dawn of history? Would numbers exist if we Homo sapiens weren’t around to discover them? What’s so special about weird numbers like pi and the Fibonacci sequence? What about rational, irrational, real, and imaginary numbers? Why do we need them? Two veteran math educators explain it all in ways even the most math phobic will find appealing and understandable. You’ll never look at those squiggles on your calculator the same again.
