These three volumes present an original exploration of all aspects of water--social, cultural, political, religious, historical, economic and technological--from ancient times until the present day. Among the varied themes, the contributors examine the changing histories of water as a private or common good, the politics of water at local, urban, national and international level, water in cities, great river plans, dams, river biographies, and cultural constructions of water--images of water in religion, myth, literature and art. With empirical and ethnographic case studies from around the world the three volumes together represent one of the most complete and up to date accounts of the central role of water in the history and development of humanity.
What is the world's tallest waterfall? How do dams help generate water power? What happens when a waterwheel spins? This series explores the causes and effects that shape our world. From the underwater volcanoes that sprout into islands, to the rushing waterfalls that spark electric currents, this series demonstrates how both natural and man-made phenomena occur.
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives.
This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms.
The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
In the opening pages of "the old battle-ax" Adelaide Adams' debut appearance, Murder a la Richelieu, Anita Blackmon signals her readers that she is humorously aware of the grand old, much-mocked but much-read "Had I But Known" tradition that she is mining when she has Adelaide declare: "Had I suspected the orgy of bloodshed upon which we were about to embark, I should then and there, in spite of my bulk and an arthritic knee, have taken shrieking to my heels." Unfortunately, Adelaide confides: "There was nothing on this particular morning to indicate the reign of terror into which we were about to be precipitated. Coming events are supposed to cast their shadows before, yet I had no presentiment about the green spectacle case which was to play such a fateful part in the murders, and not until it was forever too late did I recognize the tragic significance back of Polly Lawson's pink jabot and the Anthony woman's false eyelashes." Well! What reader can stop there? Adelaide goes on with much gusto and foreboding to relate the murderous events at the Hotel Richelieu, an establishment in an unnamed southern city (clearly Little Rock, Arkansas). Adelaide is a wonderful character: tough on the outside but rather a sentimentalist within, given to the heavy use of cliches yet actually quite acute. The life in and inhabitants of the old hotel are well-conveyed, the pace and events lively and the mystery complicated yet clear (and at the same time fair with the readers). Perhaps most enjoyable of all is the author's strong sense of humor, ably conveyed through Adelaide's memorable narration. Blackmon clearly appreciated that HIBK tales can be a tad implausible in their incredible convolutions (as can the classical Golden Age mystery in general) and she has a lot of fun with genre conventions. Her readers should have a lot of fun too."
Two young people, two stories. One country. Southern Sudan, 2008: Nya is going to the pond to fetch water for her family there and back, twice a day. She walks for eight hours every day to perform this seemingly simple task. Southern Sudan, 1985: Salva is walking away from his ruined village to find safety if there is any safety in his war-torn homeland. His journey across Africa to Ethiopia and then to Kenya and beyond will take many years. Salva is a survivor, and his story goes on to intersect with Nya's in an astonishing and moving way. This mesmerizing dual narrative by award-winning author Linda Sue Park is a fictionalised account of true events and shows us that in a troubled country, determined survivors may find the future they are hoping for.
