The Decomposition Of Jack

The Decomposition of Jack

Award-winning author Kristin O’Donnell Tubb delivers a funny and poignant middle grade contemporary novel about family and friendship as Jack deals with his parents’ divorce while also searching for a mysterious cougar in the Tennessee hills. Perfect for fans of Leslie Connor and Lynda Mullaly Hunt. A Junior Library Guild Selection! Middle school is always hard, but when you’re known as the Roadkill Kid, well, it’s even harder. Jack’s mom collects roadkill—it’s her job, and she’s very good at it. Ever since Jack’s mom and dad got divorced, Jack has stepped into the role of Mom’s co-scientist. One day while tending to the roadkill garden, Jack believes he spots a cougar in the wilderness beyond his backyard. A cougar in Tennessee? They’re supposed to be extinct. So, when Jack has to choose an animal to research for his Earth Science class, he picks cougar. As pressure mounts on Jack to complete his project and to be Mom’s business partner, the mystery of the cougar feels too big to solve. Jack knows what the decomposition of an animal—and a family—looks like, so can he figure out how to bring them back to life?

Ecology and Management of Forest Soils

Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.
