Book excerpt: The yellowheaded spruce sawfly, Pikonema alaskensis Rohwer (Hymenoptera: Tenthredinidae), is a destructive defoliator of young spruce trees. Early-instar larvae feed predominantly in the lower crown, while late-instar larvae disperse upwards to complete feeding and development in the upper crown. The role of larval parasitism with respect to this dispersal behaviour was investigated. Both early and late-instar larvae had reduced parasitism in the upper crown as opposed to the lower crown, indicating that this region was enemy-free space. Despite parasitism costs in the lower crown, early-instar larvae had better overall survival in this crown level due to better quality resources. The role of parasitism and resources changed as larvae aged and dispersed within the tree crown, therefore, stressing the need to examine both bottom-up (i.e. resources) and topdown (i.e. natural enemies) factors when exploring their influence on the behaviour of insect herbivores.

Book excerpt: Males account for roughly 50 percent of the global population, but in America and other places, they account for over 85 percent of violent crime. A graph of relative risk of death in human males shows that mortality is high immediately following birth, falls during childhood, then exhibits a distinct rise between the ages of 15 and 35—primarily the result of accidents, violence, and risky behaviors. Why? What compels males to drive fast, act violently, and behave stupidly? Why are men's lives so different from those of women? Men presents a new approach to understanding the human male by drawing upon life history and evolutionary theory. Because life history theory focuses on the timing of, and energetic investment in, particular aspects of physiology, such as growth and reproduction, Richard Bribiescas and his fellow anthropologists are now using it in the study of humans. This has led to an increased understanding of human female physiology—especially growth and reproduction—from an evolutionary and life history perspective. However, little attention has been directed toward these characteristics in males. Men provides a new understanding of human male physiology and applies it to contemporary health issues such as prostate cancer, testosterone replacement therapy, and the development of a male contraceptive. Men proves that understanding human physiology requires global research in traditionally overlooked areas and that evolutionary and life history theory have much to offer toward this endeavor.

Book excerpt: Boreal mixedwood sites, an ecologically & economically valuable component of Ontario's forested landscape, are typically dominated by hardwoods soon after major disturbances such as clear-cutting. Alternative harvesting methods may help reduce the level of competition in the regeneration environment and enrich the conifer content. This report describes field trials in northern Ontario that tested approaches for maintaining or increasing the conifer component in hardwood-dominated stands. The report explains the context & rationale for the trials; documents the locations, designs, layouts, & methods to facilitate reassessment over the long term; and presents responses observed during the first three years of treatment.

Available in PDF, EPUB and Kindle. Book excerpt: Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.

Book excerpt: This book concentrates on invasive arthropods damaging to agriculture, although relevant examples and discussions with other organisms and situations are included. Some socio-political facets are considered in overviews of plant health protection programs, including the origins of regulatory plant health in the United States, environmental and economic costs of alien arthropods, and international standards and avenues for sharing information about pests. Risk assessment is a vital scientific component of efforts to thwart the negative effects of invasive species, and some chapters deal with pathways of introduction, predicting the invasive potential of arthropods, and forecasting the likely geographic distribution of exotic insects. New eradication, control and quarantine treatment methods have been developed for use in programs against invasive species, and these are addressed in a series of chapters. Biological control has been at the nexus of the invasive species debate because the benefits sought after through the deliberate introduction of beneficial organisms may have unintended and undesirable negative effects. Accordingly, chapters are devoted to these topics.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.
