Book excerpt: "The sex imperative - the irresistible impulse to engage in sexual relations - has enabled animals to share their genes and evolve. Maxwell traces the progress of sex from the simple sharing of genes between cells to the elaborate courtship rituals that developed so sperm could merge with egg. In the effort to join sperm and egg, species have developed some astounding and unusual sexual adaptations. As Maxwell vividly describes the sex lives of various creatures, he attests to the resiliency and amazing adaptability of life to its everchanging environment. By focusing on the diversity of animal sexual relationships, Maxwell enables us to question the very basis of sexuality: What is sex? Why did it evolve? How does sexuality and survival shape the social behavior of animals and humans? The sex imperative is indeed the driving force behind Darwin's theory of random variation and natural selection, better known as "survival of the fittest." Maxwell goes so far as to investigate our latest accomplishment in the science of begetting offspring: genetic engineering." "This awe-inspiring and unique work celebrates the power and wonder of life and sexuality of all creatures - including humans. After reading this engrossing and illuminating work, no one will ever think of evolution in the same way."--Jacket

Download or read book Amphibians and Reptiles of Wisconsin written by Joshua M. Kapfer and published by . This book was released on 2022 with total page 1176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibians and reptiles represent an essential and interesting component of Wisconsin's wildlife. Eighteen species of amphibian and thirty-six species of reptile occupy landscapes across the state. They live in aquatic habitats that range from small streams to large lakes, and from open prairies to mature forests on land. These species are vital members of the biological communities in which they occur, acting as important predators, prey, and competitors, while also providing a wide variety of additional ecological functions. However, many amphibians and reptiles have experienced drastic population declines and even local extinctions in Wisconsin due to habitat loss and degradation, overharvesting, the introduction of invasive species, pollution, and other factors. This comprehensive volume, by an expert team of editors and contributors, consolidates the current state of scientific knowledge, aims to expand public knowledge and appreciation of Wisconsin's natural legacy, and brings out the herpetologist in all of us. This long-awaited, state-of-the-field synthesis also includes hundreds of color photographs and illustrations, state-level and North American range maps, dichotomous keys, and research and conservation anecdotes that will entertain and inform even the most dedicated nature lover. Amphibians and Reptiles of Wisconsin is set to become a lasting resource and armchair companion for anyone in the Midwest interested in the state's natural history and amphibian and reptile fauna.
Download or read book Bound Lives written by Rachel Sarah O'Toole and published by University of Pittsburgh Pre. This book was released on 2012-04-15 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bound Lives chronicles the lived experience of race relations in northern coastal Peru during the colonial era. Rachel Sarah O'Toole examines how Andeans and Africans negotiated and employed casta, and in doing so, constructed these racial categories. Royal and viceregal authorities separated "Indians" from "blacks" by defining each to specific labor demands. Casta categories did the work of race, yet, not all casta categories did the same type of work since Andeans, Africans, and their descendants were bound by their locations within colonialism and slavery. The secular colonial legal system clearly favored indigenous populations. Andeans were afforded greater protections as "threatened" native vassals. Despite this, in the 1640s during the rise of sugar production, Andeans were driven from their assigned colonial towns and communal property by a land privatization program. Andeans did not disappear, however; they worked as artisans, muleteers, and laborers for hire. By the late seventeenth and early eighteenth centuries, Andeans employed their legal status as Indians to defend their prerogatives to political representation that included the policing of Africans. As rural slaves, Africans often found themselves outside the bounds of secular law and subject to the judgments of local slaveholding authorities. Africans therefore developed a rhetoric of valuation within the market and claimed new kinships to protect themselves in disputes with their captors and in slave-trading negotiations. Africans countered slaveholders' claims on their time, overt supervision of their labor, and control of their rest moments by invoking customary practices. Bound Lives offers an entirely new perspective on racial identities in colonial Peru. It highlights the tenuous interactions of colonial authorities, indigenous communities, and enslaved populations and shows how the interplay between colonial law and daily practice shaped the nature of colonialism and slavery.

Available in PDF, EPUB and Kindle. Book excerpt: The Florida Everglades ecosystem is recognised world-wide as a significant wetland whose natural processes have been altered and remain threatened. State and Federal US agencies face critical decisions about the course of conservation and restoration efforts. Synthesising nearly ten years of laboratory and field research of the Duke University Wetland Center, this book provides the long-term integrated scientific studies needed to understand the functioning of this region. Background information about the current and historical ecological conditions of the region set the context for reports of long-term research projects, while a series of gradient studies determine the effects of hydrology and nutrient changes. Subsequent sections present models for predicting responses to various conditions and analyse the studies and models, focusing on management and restoration of the Everglades.
Download or read book Wildlife Ecology and Management in Mexico written by Raul Valdez and published by Texas A&M University Press. This book was released on 2019-01-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.
