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.
