Book Description
While the subject of environmental stress in animals is broad, the available information is fragmentary and lacks an up-to-date overview and analysis. Environmental Stress and Cellular Response in Arthropods fills these knowledge gaps. Written by three experts from the same institution, the chapters have a consistency not often found in multi-authored or contributed books. The authors describe environmental stress in arthropods, specifically Drosophila and analyze the process in all its aspects, from biochemical mechanisms to effects on the whole organism. Incorporating new information that has become available in recent years, the authors explore hypotheses about the integrated response these systems often have. They explore topics ranging from disturbance of homeostasis, changes in metabolic processes, damage of cellular structures to acquired tolerance, effects on aging processes, and survival and cell death. By analyzing all these aspects in detail at the molecular, biochemical, and physiological level of the cell, the authors give you a thorough look at the relationship between an organism and its environment at the cellular level.

Book Description
The Antarctic Peninsula is characterized by harsh and dynamic environmental conditions. Organisms inhabiting this environment may be challenged by extremes of low temperature, limited water availability, dramatic seasonal fluctuations of light availability and ultraviolet radiation, and high salinity. This dissertation describes three projects examining the tolerance and physiological responses to such environmental stress of two Antarctic arthropods, the midge Belgica antarctica and the collembolan Cryptopygus antarcticus. The first investigation examined the ability of B. antarctica larvae to resist inoculative freezing at subzero temperatures and instead dehydrate as a strategy for winter survival (i.e., cryoprotective dehydration). When cooled to subzero temperatures in the presence of ice, the body fluid melting point was depressed to near equilibrium with the ambient temperature, due to reductions of body water content and the accumulation of several osmolytes, suggesting larvae can undergo cryoprotective dehydration at subzero temperatures. Under more natural conditions, the use of cryoprotective dehydration versus freeze tolerance for winter survival appears to depend upon the moisture content of the surrounding soil. The purpose of the second study was to assess the tolerance and physiological response to desiccation of C. antarcticus under ecologically-relevant conditions. Slow dehydration at high relative humidities characteristic of the austral summer induced the accumulation of several organic osmolytes and increased the tolerance of water loss. A mild drought acclimation further increased the subsequent desiccation tolerance of C. antarcticus. The springtails were also susceptible to water loss at subzero temperatures and likely rely upon such dehydration as a key component for winter survival. As B. antarctica microhabitats may be periodically inundated with seawater, the final investigation examined the osmotic response and tolerance of larvae to hyperosmotic seawater exposure. The larvae displayed an impressive tolerance of the osmotic stress, as ~50% survived a 6-d submergence in pure seawater. Hyperosmotic stress induced the accumulation of organic osmolytes and resulted in a significant positive correlation between the rate of oxygen consumption and larval body water content. Finally, a brief seawater acclimation enhanced the subsequent tolerance of freezing and dehydration, but reduced the tolerance of heat shock.

Book Description
An introduction to the intriguing world of insects, from bullet ants to butterflies. Designed as an introduction to the intriguing world of insect biology, this book examines familiar entomological topics in nontraditional ways. Author David B. Rivers gives important concepts relatable context through a pop culture lens, and he covers subjects that are not typical for entomology textbooks, including the impact of insects on the human condition, the sex lives of insects, why insects are phat but not fat, forensic entomology, and the threats that some insects pose to humanity. Each chapter presents clear and concise key concepts, chapter reviews, review questions following Bloom’s taxonomy of learning, web links to videos and other resources, and breakout boxes (called Fly Spots) that capture student interest with unique and entertaining facts related to entomology. Focusing on both traditional and cutting-edge aspects of insect biology and packed with extensive learning resources, Insects covers a wide range of topics suitable for life science majors, as well as non-science students, including: • the positive and negative influences of insects on everyday human life • insect abundance • insect classification (here presented in the context of social media) • insect feeding, communication, defense, and sex • how insects are responding to climate change • forensic entomology • how insects can be used as weapons of war • how insects relate to national security • why insects have wings • how to read pesticide labels

Book Description
The Science of Forensic Entomology builds a foundation of biological and entomological knowledge that equips the student to be able to understand and resolve questions concerning the presence of specific insects at a crime scene, in which the answers require deductive reasoning, seasoned observation, reconstruction and experimentation—features required of all disciplines that have hypothesis testing at its core. Each chapter addresses topics that delve into the underlying biological principles and concepts relevant to the insect biology that forms the bases for using insects in matters of legal importance. The book is more than an introduction to forensic entomology as it offers in depth coverage of non-traditional topics, including the biology of maggot masses, temperature tolerances of necrophagous insects; chemical attraction and communication; reproductive strategies of necrophagous flies; archaeoentomology, and use of insects in modern warfare (terrorism). As such it will enable advanced undergraduate and postgraduate students the opportunity to gain a sound knowledge of the principles, concepts and methodologies necessary to use insects and other arthropods in a wide range of legal matters.

Book Description
Cutting across traditional subject boundaries, Principles of Ecotoxicology, Fourth Edition gives readers an integrated view of ecotoxicology, from molecules to ecosystems. This new edition of a bestselling textbook continues to emphasize principles rather than practice, providing the interdisciplinary perspective and grounding required for research. Organized into three sections, the book first describes the molecular structures, properties, and environmental fate of pollutants. It then deals with the effects of pollutants on living organisms at the molecular, cellular, and individual levels. Moving into population biology and population genetics, the third part of the book addresses a question of great interest to ecologists: What effects do pollutants have at the levels of population, community, and the whole ecosystem? The book also looks at how ecotoxicology is used in the biomonitoring of environmental pollution, the investigation of pollution problems, the conducting of field trials, the study of the development of resistance, and the growing area of environmental risk assessments. Throughout, examples and case studies illustrate the principles. This updated fourth edition includes new material on nanoparticle pollution, bioaccumulation, biomarkers, and chemical warfare in nature, as well as a new chapter on the future directions of ecotoxicology. A concise textbook that will also appeal to practicing ecotoxicologists, it provides a solid basis for understanding what happens to chemicals in the real world, where they go, how they ultimately degrade, and how they affect the individuals and populations that encounter them. What's New in This Edition Revised and updated material throughout A chapter on future directions of ecotoxicology New material on nanoparticle pollution and chemical warfare in nature Expanded coverage of bioaccumulation, biomarkers, and risk assessment for affected populations More case studies, many from the United States Discussion of neurotoxic and behavioral effects of pollutants Recent research on the decline of vultures and effects of neonicotinoids on bees Organic Pollutants: An Ecotoxicological Perspective, Second Edition(CRC Press, 2008), a companion volume to this book, covers the mechanistic aspects of ecotoxicology in more depth.

Book Description
With the exception of a few tropical medicine schools worldwide, current medical education programs include almost zero discussion of the interface between infectious diseases and entomology. That is why this book was initially published in the first edition almost 17 years ago. The third edition of this valuable infectious disease entomology book updates all existing chapters with the newest scientific developments described in the medical and entomological literature in addition to covering 10 entirely new topics not addressed in previous editions, which include: · arthropod identification controversies · early beginnings of public health and disease control · red-meat allergy · updates on vaccine development for dengue and malaria · discussion of Chikungunya and Zika viruses · American Boutonnneuse Fever · the newest controversies in Lyme disease · recent findings of viruses in ticks · bed bug bite reactions · Morgellons disease (an imaginary infectious disease)
