The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing mechanisms.
A revelatory look at why we dehumanize each other, with stunning examples from world history as well as today's headlines
"Brute." "Cockroach." "Lice." "Vermin." "Dog." "Beast." These and other monikers are constantly in use to refer to other humans—for political, religious, ethnic, or sexist reasons. Human beings have a tendency to regard members of their own kind as less than human. This tendency has made atrocities like the Holocaust, the genocide in Rwanda, and the slave trade possible, and yet we still find it in phenomena such as xenophobia, homophobia, military propaganda, and racism. Less Than Human draws on a rich mix of history, psychology, biology, anthropology and philosophy to document the pervasiveness of dehumanization, describe its forms, and explain why we so often resort to it.
David Livingstone Smith posits that this behavior is rooted in human nature, but gives us hope in also stating that biological traits are malleable, showing us that change is possible. Less Than Human is a chilling indictment of our nature, and is as timely as it is relevant.
"I tried to have well-trained police officers and deputies. Bill is paying attention to the training of beekeepers." Johannes F. Spreen, retired police commissioner of Detroit and sheriff of Oakland County, Michigan.
"Honey's anti-bacterial qualities may make it valuable in treating microbes that have become resistant to antibiotics such as methicillin-resistant Staphylococcus aureus-MRSA." Dr. Diane Holloway, formerly in practice at Presbyterian Hospital, Dallas, Texas.
"This knowledge should help you in minimizing any significant impact that the Africanized bee could have on your daily life." Fire Chief Robert Biscoe, Fire District of Sun City West, Arizona.
This well-illustrated text is perfect for beginning beekeepers, experienced beekeepers and their employees, entomology students, and the layman. It offers instructions and information for:
Problems with helpers, animals, people, health, and disasters Working with beeswax, pollen, enzymes, and package bees Dealing with diseases, mites, colony collapse, and Africanized bees Robbing, extracting, bee removal, re-queening and queen rearing
In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together--as a swirling cloud of bees--to their new home. Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution.
An impressive exploration of animal behavior, Honeybee Democracy shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

Dave Goulson became obsessed with wildlife as a small boy growing up in rural Shropshire, starting with an increasingly exotic menagerie of pets. When his interest turned to the anatomical, there were even some ill-fated experiments with taxidermy. But bees are where Goulson's true passion lies—the humble bumblebee in particular.
Once commonly found in the marshes of Kent, the English short-haired bumblebee went extinct in the United Kingdom, but by a twist of fate still exists in the wilds of New Zealand, the descendants of a few pairs shipped over in the nineteenth century. Dave Goulson's passionate quest to reintroduce it to its native land is one of the highlights of a book that includes original research into the habits of these mysterious creatures, history's relationship with the bumblebee, and advice on how to protect the bumblebee for future generations.
One of the United Kingdom's most respected conservationists and the founder of the Bumblebee Conservation Trust, Goulson combines lighthearted tales of a child's growing passion for nature with a deep insight into the crucial importance of the bumblebee. He details the minutiae of life in the nest, sharing fascinating research into the effects intensive farming has had on our bee population and the potential dangers if we are to continue down this path.

Goes Beyond Dramatics to the Nitty Gritty of Real Practice
While many books, movies, and television shows have made forensic entomology popular, this book makes it real. Going beyond dramatics to the nitty gritty of actual practice, it covers what to search for when recovering entomological evidence, how to handle items found at the crime scene, and how to use entomological knowledge in legal investigations.
Not so long ago, in a small island nation in the South Pacific, beekeepers produced a most peculiar honey. It was much darker than the clover honey everyone put on their toast in the morning, and it tasted very different. In fact, the honey was a problem: it was hard to get out of the combs, and even harder for beekeepers to sell.
Today that honey, manuka from New Zealand, is known around the world. It fetches high prices, and beekeepers do everything in their power to produce as much of it as possible. Wound dressings containing manuka honey are used in leading hospitals, and it has saved the lives of patients infected with disease-causing bacteria that are resistant to standard antibiotic drugs. In so doing it has forced the medical profession to rethink its position on the therapeutic properties of natural products.
This book chronicles the remarkable ‘rags-to-riches’ story of manuka honey, as seen through the eyes of a New Zealand beekeeping specialist who watched it unfold from the very beginning. It’s a great tale of science, in which an inquisitive university lecturer found something totally unexpected in a product everyone had written off. It’s also an entertaining account of the way that seemingly simple discovery caught the international media’s attention, helping enterprising New Zealanders to develop manuka honey-based products and take them all around the globe.
But above all else it’s a story of hope for the future, sounding a note of optimism in a world that for good reason feels saddened and sometimes even afraid about the future of the special relationship we humans have always had with those marvellous creatures, the honey bees.
A Sting in the Tale, Dave Goulson's account of a lifetime studying bees, was a powerful call to arms for nature lovers everywhere. Brilliantly reviewed, it was shortlisted for the Samuel Johnson Prize for the best nonfiction book of the year, and debuted the already renowned conservationist's ability to charm and educate, and tell an absorbing story.
In A Buzz in the Meadow, Goulson returns to tell the tale of how he bought a derelict farm in the heart of rural France. Over the course of a decade, on thirty-three acres of meadow, he created a place for his beloved bumblebees to thrive. But other creatures live there too, myriad insects of every kind, many of which Goulson had studied before in his career as a biologist. You'll learn how a deathwatch beetle finds its mate, why butterflies have spots on their wings, and see how a real scientist actually conducts his experiments.
But this book is also a wake-up call, urging us to cherish and protect life in all its forms. Goulson has that rare ability to persuade you to go out into your garden or local park and observe the natural world. The undiscovered glory that is life in all its forms is there to be discovered. And if we learn to value what we have, perhaps we will find a way to keep it.
The term zoology was fairly simple back in the 4th Century BC, when the ancient Greek philosopher, Aristotle, proposed some of the first broad of classifications of living beings. He was logically divided and categorized all living beings into animals.
Topics cover in Zoology: An Introduction are Biodiversity, Taxonomy, Classification of Animals I, Classification of Animals II, Animal Tissues, Nutrition and Food in Animals, Respiration System in Animals, Animal Circulatory System, Excretion and Osmoregulation, Movement and Locomotion, Nervous System and Reproduction in Animals.
Ideal for nonscience majors and anyone seeking to learn more about insects and their arthropod relatives, Bugs Rule! offers a one-of-a-kind gateway into the world of these amazing creatures.
The book opens with a general introduction to entomology and includes coverage of the major insects (and mites) that cause harm to crops, livestock and humans. The important beneficial species are also included. Organisms are described in a classification of insect Orders and Families. The emphasis is on morphological characters of major taxonomic divisions, “spot characters” for the recognition of Families, and the life histories, damage symptoms and economic importance of the various pest species.
The book is beautifully illustrated in full colour with more than 400 figures showing both the organisms and the damage caused to plants with diagnostic characters indicated by arrows. Coverage is world-wide and includes much material stemming from the vast personal experience of the author.
