Book Description
Straddling temperate forests and grassland biomes and stretching along the coastline of two Great Lakes, Wisconsin contains tallgrass prairie and oak savanna, broadleaf and coniferous forests, wetlands, natural lakes, and rivers. But, like the rest of the world, the Badger State has been transformed by urbanization and sprawl, population growth, and land-use change. For decades, industry and environment have attempted to coexist in Wisconsin—and the dynamic tensions between economic progress and environmental protection makes the state a fascinating microcosm for studying global environmental change. The Vanishing Present brings together a distinguished set of contributors—including scientists, naturalists, and policy experts—to examine how human pressures on Wisconsin’s changing lands, waters, and wildlife have redefined the state’s ecology. Though they focus on just one state, the authors draw conclusions about changes in temperate habitats that can be applied elsewhere, and offer useful insights into future of the ecology, conservation, and sustainability of Wisconsin and beyond. A fitting tribute to the home state of Aldo Leopold and John Muir, The Vanishing Present is an accessible and timely case study of a significant ecosystem and its response to environmental change.

Book Description
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.
