Recent studies have shown that genetic polymorphisms play an important role in structuring the seasonal life cycles of insects, complementing an earlier emphasis on the effects of environmental factors. This book presents current ideas and recent research on insect life--cycle polymorphism in a series of carefully prepared chapters by international experts, covering the full breadth of the subject in order to give an up-to-date view of how life cycles are controlled and how they evolve. By consolidating our view of insect life--cycle polymorphism in this way, the book provides a staging point for further enquiries. The volume will be of interest to a wide variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the extraordinarily complex ecological strategies of insects and other organisms.
The last of six books in Arabella Buckley's Eyes and No Eyes series. This book covers insects and their habitats. Subjects include bees, butterflies, moths, beetles, grasshoppers and many more. Intended for early readers, the book uses simple language in each lesson. First published in 1901, this edition is derived from the original book with 8 color illustrations and numerous black and white illustrations by A. Fairfax Muckley. As always, this edition is complete and unabridged.
The Evolution of Insect Life Cycles by Fritz Taylor,Richard Karban Pdf
This book was developed out of a symposium at the XVII International Congress of Entomology held in Hamburg, Germany, on August 21, 1984. This symposium was organized by Drs. William Bradshaw and Hugh Dingle, who subsequently asked us to edit the proceedings. The chapters represent, for the most part, papers that were read in Hamburg but have been expanded and updated. The goal of this volume is to provide a comprehensive view of current research on insect life cycles, including field and laboratory studies, broad comparisons among species or local populations, and intensive studies of single populations, as well as theoretical research. Of necessity, given the magnitude of research now being carried out on insects, some important research programs are not included, and therein lie the makings of future volumes. This volume is divided into three parts. The first part, Geographical Patterns in Insect Life Cycles, explores various applications of a comparative method that has been valuable in investigating the potential for variability in life history parameters and the relation of these parameters to important variables in the environment.
The Insect Crisis: The Fall of the Tiny Empires That Run the World by Oliver Milman Pdf
A devastating examination of how collapsing insect populations worldwide threaten everything from wild birds to the food on our plate. From ants scurrying under leaf litter to bees able to fly higher than Mount Kilimanjaro, insects are everywhere. Three out of every four of our planet’s known animal species are insects. In The Insect Crisis, acclaimed journalist Oliver Milman dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history. What is causing the collapse of the insect world? Why does this alarming decline pose such a threat to us? And what can be done to stem the loss of the miniature empires that hold aloft life as we know it? With urgency and great clarity, Milman explores this hidden emergency, arguing that its consequences could even rival climate change. He joins the scientists tracking the decline of insect populations across the globe, including the soaring mountains of Mexico that host an epic, yet dwindling, migration of monarch butterflies; the verdant countryside of England that has been emptied of insect life; the gargantuan fields of U.S. agriculture that have proved a killing ground for bees; and an offbeat experiment in Denmark that shows there aren’t that many bugs splattering into your car windshield these days. These losses not only further tear at the tapestry of life on our degraded planet; they imperil everything we hold dear, from the food on our supermarket shelves to the medicines in our cabinets to the riot of nature that thrills and enlivens us. Even insects we may dread, including the hated cockroach, or the stinging wasp, play crucial ecological roles, and their decline would profoundly shape our own story. By connecting butterfly and bee, moth and beetle from across the globe, the full scope of loss renders a portrait of a crisis that threatens to upend the workings of our collective history. Part warning, part celebration of the incredible variety of insects, The Insect Crisis is a wake-up call for us all.
