Grasslands comprise the largest and most diverse set of ecosystems in the United States and are among the most extensive in the world. Characterized by scanty rainfall, these western grasslands are too dry for crop production and are used almost exclusively for grazing livestock. The grasslands on the western edge of the Great Plains, known as the

Mormon crickets (Anabrus simplex) are flightless North American shield-backed katydids that exist with a broad range of phenotypic variation including coloration, body size, movement behavior, and male calling behavior. Population types of Mormon crickets are classified as band-forming, non-band-forming, or intermediate based on estimated population density and movement behavior. Despite marked differences in morphology and behavior, these population types are still considered the same species although there is some evidence suggesting that they are genetically distinct (Bailey et al 2005). Mormon cricket morphology has been systematically described in terms of allometric, or size-correlated differences in shape between populations of Mormon crickets. The patterns of relationships between morphological characters have also been examined using morphological integration to see how they have changed over evolutionary time. Twenty-three morphological features of Mormon crickets collected from five populations in 2008 were measured and compared to the geometric mean for each individual. Shape differences by sex and by population type were tested for significance using two-way ANOVA. Principal component analysis of the covariance matrices was employed for data reduction and to explore the interactions between characters among BF and NBF Mormon crickets in terms of variance explained by size and shape versus shape alone. Correlation analysis was employed to test the relationships between morphological characters and movement patterns. Seven hypotheses of differences in covariation structure, or integration, were tested by constructing correlation matrices of the morphological variables and subjecting them to matrix correlations and Mantel tests. Integration patterns were discussed in terms of shape differences in morphology, local ecological conditions, and selection pressures by population.

The essential illustrated introduction to insects for nonscience majors Bugs Rule! provides a lively introduction to the biology and natural history of insects and their noninsect cousins, such as spiders, scorpions, and centipedes. This richly illustrated textbook features more than 830 color photos, a concise overview of the basics of entomology, and numerous sidebars that highlight and explain key points. Detailed chapters cover each of the major insect groups, describing their physiology, behaviors, feeding habits, reproduction, human interactions, and more. 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. Places a greater emphasis on natural history than standard textbooks on the subject Covers the biology and natural history of all the insect orders Provides a thorough review of the noninsect arthropods, such as spiders, scorpions, centipedes, millipedes, and crustaceans Features more than 830 color photos Highlights the importance of insects and other arthropods, including their impact on human society An online illustration package is available to professors

This book explores one of the most discussed and investigated novel foods in recent years: edible insects. The increasing demand for alternative protein sources worldwide had led the Food and Agriculture Organization of the United Nations (FAO) to promote the potential of using insects both for feed and food, establishing a program called “Edible Insects.” Although several social, environmental, and nutritional benefits of the use of insects in the human diet have been identified, the majority of the population in Western countries rejects the idea of adopting insects as food, predominantly for cultural reasons. Nevertheless, international interest in promoting the consumption of insects has grown significantly, mainly in North America and Europe. This trend is mostly due to increasing attention and involvement from the scientific network and the food and feed industries, as well as governments and their constituents. The book explores the current state of entomophagy and identifies knowledge gaps to inform primary research institutions, students, members of the private sector, and policymakers to better plan, develop, and implement future research studies on edible insects as a sustainable source of food. The case studies and issues presented in this book cover highly up-to-date topics such as aspects of safety and allergies for human consumption, final meat quality of animals fed with insects, the legislative framework for the commercialization of this novel food, and other relevant issues.
