Download or read book Effects of Temperature on Ectothermic Organisms written by Wolfgang Wieser and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of thermoregulation in endotherms has contributed much to the emergence of the concept of control theory in biology. By the same token, the study of tempera ture adjustment in ectotherms is likely to have a far-reaching influence on ideas on the regulation of metabolism in general. The reason for this is that ectotherms, in adapting to the vagaries of a thermally unstable environment, deploy a range of subtle molecular and organismic strategies. Thus the experimenter, using temperature changes as a tool, is well equipped to analyze some of these strategies. This approach has enabled some important mechanisms of temperature-induced adaptation to be elucidated; the most striking of these are the effects on metabolism of changes in the conformation of enzymes and the transfer properties of membranes. Furthermore, there is a vague but persistent feeling among those working in this field that changes in the nervous system will ultimately prove to be the agency by which many of the molecular mechanisms of temperature adaptation are controlled. Should this indeed be the case, a new phase would soon begin in our understanding of the interactions between the systemic and the cellular levels of organization. However, it is not only questions about the causes of temperature adaptation that can provide answers of potential importance to the general biologist; of equal significance are questions as to the meaning of temperature adaptation in a particular organism.
Download or read book Insects at Low Temperature written by Richard Lee and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 516 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of insects at low temperature is a comparatively new field. Only recently has insect cryobiology begun to mature, as research moves from a descriptive approach to a search for underlying mechanisms at diverse levels of organization ranging from the gene and cell to ecological and evolutionary relationships. Knowledge of insect responses to low temperature is crucial for understanding the biology of insects living in seasonally varying habitats as well as in polar regions. It is not possible to precisely define low temperature. In the tropics exposure to 10-15°C may induce chill coma or death, whereas some insects in temperate and polar regions remain active and indeed even able to fly at O°C or below. In contrast, for persons interested in cryopreservation, low temperature may mean storage in liquid nitrogen at - 196°C. In the last decade, interest in adaptations of invertebrates to low temperature has risen steadily. In part, this book had its origins in a symposium on this subject that was held at the annual meeting of the Entomological Society of America in Louisville, Kentucky, USA in December, 1988. However, the emergence and growth of this area has also been strongly influenced by an informal group of investigators who met in a series of symposia held in Oslo, Norway in 1982, in Victoria, British Columbia, Canada in 1985 and in Cambridge, England in 1988. Another is scheduled for Binghamton, New York, USA (1990).

Download or read book The Thermal Warriors written by Bernd Heinrich and published by . This book was released on 1996 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: All bodily activity is the result of the interplay of vastly complex physiological processes, and all of these processes depend on temperature. For insects, the struggle to keep body temperature within a suitable range for activity and competition is often a matter of life and death. A few studies of temperature regulation in butterflies can be found dating back to the late 1800s, but only recently have scientists begun to study the phenomenon in other insects. In The Thermal Warriors Bernd Heinrich explains how, when, and in general what insects regulate their body temperature and what it means to them. As he shows us, the ingenuity of the survival strategies insects have evolved in the irreducible crucible of temperature is astonishing: from shivering and basking, the construction of turrets (certain tiger beetles), and cooling with liquid feces to stilting (some desert ants and beetles), "panting" in grasshoppers and "sweating cicada," and counter- and alternating-currents of blood flow for heat retention and heat loss. In The Thermal Warriors Heinrich distills his great reference work, The Hot-Blooded Insects, to its essence: the most significant and fascinating stories that illustrate general principles, all conveyed in the always engaging prose we have come to expect from this author.
Download or read book Low Temperature Biology of Insects written by David L. Denlinger and published by Cambridge University Press. This book was released on 2010-01-28 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low temperature is a major environmental constraint impacting the geographic distribution and seasonal activity patterns of insects. Written for academic researchers in environmental physiology and entomology, this book explores the physiological and molecular mechanisms that enable insects to cope with a cold environment and places these findings into an evolutionary and ecological context. An introductory chapter provides a primer on insect cold tolerance and subsequent chapters in the first section discuss the organismal, cellular and molecular responses that allow insects to survive in the cold despite their, at best, limited ability to regulate their own body temperature. The second section, highlighting the evolutionary and macrophysiological responses to low temperature, is especially relevant for understanding the impact of global climate change on insect systems. A final section translates the knowledge gained from the rest of the book into practical applications including cryopreservation and the augmentation of pest management strategies.

Download or read book Insects plants and microclimate written by D. M. Unwin and published by Pelagic Publishing Ltd. This book was released on 2024-08-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microclimate is the very local climate close to the ground or another surface. The microclimate around a plant is particularly complex and interesting, and an insect sitting on a leaf may be inhabiting a weather system completely different from the weather outside. An understanding of the microclimate around plants enables us to interpret the behaviour pattern of insects as they change through the day. The instruments needed for exploring microclimate need not be expensive - this book explains how many of them can be made at home or at school using inexpensive components. The colour illustrations provide a guide to the main groups of insects, and identification keys are listed for each. 9781784275334 & 9781784275341 are digital reprints of 0855462795 (1991).

Download or read book The Biomechanics of Insect Flight written by Robert Dudley and published by Princeton University Press. This book was released on 2018-06-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.
Download or read book Insect Diapause written by David L. Denlinger and published by Cambridge University Press. This book was released on 2022-02-03 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.
