Grasslands, in particular managed pastures and rangelands, are widespread, covering approximately 40% (52 million km²) of the Earth's land surface. They are dominated by members of the Poaceae - the fourth largest plant family with over 7,500 species, and also the most widespread. Grasslands constitute a major biome on all continents except Antarctica and also represent the most important food crop on Earth with corn, wheat, maize, rice and millet accounting for the majority of our agricultural output.Grasses and Grassland Ecology provides an ecologically orientated introduction to this influential group of plants, summarizing the most recent scientific research in ecology and agriculture in the context of the older, classic literature. Ten chapters cover the morphology, anatomy, physiology and systematics of grasses, their population, community and ecosystem ecology, their global distribution, and the effects of disturbance and grassland management. This comprehensive and accessible textbook is suitable for graduate level students as well as professional researchers in the fields of plant ecology, rangeland science, crop science, and agriculture.

Discover the extraordinary role of plants in modern forensics, from their use as evidence in the trials of high profile murderers such as Ted Bundy to high value botanical trafficking and poaching. We are all familliar with the role of blood spatters or fingerprints in solving crimes, from stories in the media of DNA testing or other biological evidence being used as the clinching evidence to incriminate a killer. This book lifts the lid on the equally important evidence from plants at a crime scene, from the incriminating presence of freshwater plants in the lungs of a drowning victim, to rare botanical poisons in the evening gin and tonic, to exotic trafficked flowers and drugs. In Planting Clues, David Gibson explores how plants can help to solve crimes, as well as how plant crimes are themselves solved. He discusses the botanical evidence that proved important in bringing a number of high-profile murderers such as Ian Huntley (the 2002 Shoham Murders), and Bruno Hauptman (the 1932 Baby Lindbergh kidnapping) to trial, from leaf fragments and wood anatomy to pollen and spores. Throughout he traces the evolution of forensic botany, and shares the fascinating stories that advanced its progress.

This comprehensive handbook represents a definitive state-of-the-art overview of grasslands from multiple, interdisciplinary and global perspectives.Despite the real and intrinsic values that grasslands offer, they are globally subject to fragmentation, habitat and species loss, and they are increasingly threatened by climate change. From a human societal perspective, grasslands are central to much of our culture and represent areas where agriculture first arose. The Routledge Handbook of Grasslands brings together an interdisciplinary team of global authors to present a much needed and vitally important overview of the new and ongoing debates around the values of and threats to grasslands. Reflecting the broad range of issues, debates and threats, this handbook is divided into five parts:Part I: Deep Roots, Dynamic Futures: Understanding the Science of GrasslandsPart II: Living Complexity: Grassland Function, Biodiversity, and RenewalPart III: Working Landscapes: Innovation and Tradition in Grassland StewardshipPart IV: Social-Ecological Ties: Grassland Services, Justice, and GovernancePart V: Landscapes of Meaning: Cultural and Creative Perspectives on GrasslandsDrawing on the experience of researchers, practitioners and managers, this handbook is the only grassland-oriented text to include social, economic, policy and cultural value dimensions of grasslands, as well as an up-to-date coverage of the agronomy and ecology of these environments. This handbook concludes with a forward-thinking chapter that discusses the future of grasslands, further directions, threats and innovations.The Routledge Handbook of Grasslands is essential reading for students and scholars of grassland ecology, management and conservation as well as policy and management practitioners involved in grassland management and governance, as well as natural resources more broadly.

Grasslands are the most extensive terrestrial biome on Earth and are critically important for forage, biodiversity, and ecosystem services. This book brings together an international team of researchers to review scientific knowledge of the effects of climate change on world grasslands, a process we are only just starting to understand. Part I assesses how climate change will impact on the distribution of grasslands, as well as production, biogeochemical cycling and ecosystem services. Part II considers the consequences for the spread of invasive species, demographic change, trophic-level relationships, soil biota, and evolutionary change within grassland biodiversity. Part III proposes how ecologists can respond to climate change effects, focusing on grazing systems, cultural ecology, range management, and restoration. The concluding chapter sets grasslands in the context of the Anthropocene era and identifies the vital research and conservation needs for grassland ecosystems to remain environmentally sustainable under climate change.
