Understanding how a multicellular animal develops from a single cell (the fertilized egg) poses one of the greatest challenges in biology today. Development from egg to adult involves the sequential expression of virtually the whole of an organism's genetic instructions both in the mother as she lays down developmental cues in the egg, and in the embryo itself. Most of our present information on the role of genes in development comes from the invertebrate fruit fly, Drosophila. The two authors of this text (amongst the foremost authorities in the world) follow the developmental process from fertilization through the primitive structural development of the body plan of the fly after cleavage into the differentiation of the variety of tissues, organs and body parts that together define the fly. The developmental processes are fully explained throughout the text in the modern language of molecular biology and genetics. This text represents the vital synthesis of the subject that many have been waiting for and it will enable many specific courses in developmental biology and molecular genetics to focus on it. It will appeali to 2nd and 3rd year students in these disciplines as well as in biochemistry, neurobiology and zoology. It will also have widespread appeal among researchers. Authored by one of the foremost authorities in the world. A unique synthesis of the developmental cycle of Drosophila - our major source of information on the role of genes in development. Designed to provide the basis of new courses in developmental biology and molecular genetics at senior undergraduate level. A lucid explanation in the modern language of the science.

A plane crashes on a desert island and the only survivors, a group of schoolboys, assemble on the beach and wait to be rescued. By day they inhabit a land of bright fantastic birds and dark blue seas, but at night their dreams are haunted by the image of a terrifying beast. As the boys' delicate sense of order fades, so their childish dreams are transformed into something more primitive, and their behaviour starts to take on a murderous, savage significance. First published in 1954, Lord of the Flies is one of the most celebrated and widely read of modern classics. Now fully revised and updated, this educational edition includes chapter summaries, comprehension questions, discussion points, classroom activities, a biographical profile of Golding, historical context relevant to the novel and an essay on Lord of the Flies by William Golding entitled 'Fable'. Aimed at Key Stage 3 and 4 students, it also includes a section on literary theory for advanced or A-level students. The educational edition encourages original and independent thinking while guiding the student through the text - ideal for use in the classroom and at home.

Fly just wants to have fun flying, but everyone she meets thinks she's doing it all WRONG!

Provides step-by-step instructions on tying five hundred trout flies and offers information on tying techniques, tools, and materials.

Fly is fed up with everyone studying butterflies. Flies are so much cooler! They flap their wings 200 times a second, compared to a butterfly's measly five to twelve times. Their babies-maggots-are much cuter than caterpillars (obviously). And when they eat solid food, they even throw up on it to turn it into a liquid. Who wouldn't want to study an insect like that? In an unforgettably fun, fact-filled presentation, this lovable (and highly partisan) narrator promotes his species to a sometimes engrossed, sometimes grossed-out, class of kids.

From tenements to alleyways to latrines, twentieth-century American cities created spaces where pests flourished and people struggled for healthy living conditions. In Pests in the City, Dawn Day Biehler argues that the urban ecologies that supported pests were shaped not only by the physical features of cities but also by social inequalities, housing policies, and ideas about domestic space. Community activists and social reformers strived to control pests in cities such as Washington, DC, Chicago, Baltimore, New York, and Milwaukee, but such efforts fell short when authorities blamed families and neighborhood culture for infestations rather than attacking racial segregation or urban disinvestment. Pest-control campaigns tended to target public or private spaces, but pests and pesticides moved readily across the porous boundaries between homes and neighborhoods. This story of flies, bedbugs, cockroaches, and rats reveals that such creatures thrived on lax code enforcement and the marginalization of the poor, immigrants, and people of color. As Biehler shows, urban pests have remained a persistent problem at the intersection of public health, politics, and environmental justice, even amid promises of modernity and sustainability in American cities.
