In recent years, there has been increasing interest from geoscientists in potassic ig neous rocks. Academic geoscientists have been interested in their petrogenesis and their potential value in defining the tectonic setting of the terranes into which they were intruded, and exploration geoscientists have become increasingly interested in the association of these rocks with major epithermal gold and porphyry gold-copper deposits. Despite this current interest, there is no comprehensive textbook that deals with these aspects of potassic igneous rocks. This book redresses this situation by elucidating the characteristic features of potassic (high-K) igneous rocks, erecting a hierarchical scheme that allows interpre tation of their tectonic setting using whole-rock geochemistry, and investigating their associations with a variety of gold and copper-gold deposits, worldwide. About two thirds of the book is based on a PhD thesis by Dr Daniel Muller which was produced at the Key Centre for Strategic Mineral Deposits within the Department of Geology and Geophysics at The University of Western Australia under the supervision of Professor David Groves, the late Dr Nick Rock, Professor Eugen Stumpf!, Dr Wayne Taylor, and Dr Brendon Griffin. The remainder of the book has been compiled from the literature using the collective experience of the two authors. The book is dedi cated to the memory of Dr Rock who initiated the research project but died before its completion.

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.

This book is about the plants and animals of urban areas, not the urban fringe, not encapsulated countryside but those parts of towns where man's impact is greatest. The powerful anthropogenic influences that operate in cities have, until recently, rendered them unattractive to ecologists who find the high proportion of exotics and mixtures of planted and spontaneous vegetation bewildering. They are also unused to considering fashion, taste, mowing machines and the behaviour of dog owners as habitat factors. I have always maintained, however, and I hope this book demonstrates, that there are as many interrelationships to be uncovered in a flower bed as in a field, in a cemetery as on a sand dune; and due to the well documented history of urban sites, together with the strong effects of management, they are frequently easier to interpret than those operating in more natural areas. The potential of these communities as rewarding areas for study is revealed in the literature on the pests of stored products, urban foxes and birds. The journals oflocal natural history societies have also provided a rich source of material as amateurs have never been averse to following the fortunes of their favourite groups into the heart of our cities. It is predictable that among the few professionals to specialize in this discipline have been those enclosed in West Berlin, who must be regarded as among the leading exponents of urban ecology.

In this book metal deposits, in particular those of non-ferrous and precious metals, are classified and analyzed in terms of their plate tectonic settings. This approach allows a meaningful treatment of metal deposits of different types and provides significant insights into both their genesis and formative environments. The updated 2nd edition incorporates the most significant advances in economic geology of the last 5 years. Particular attention is paid to the geological settings and generative models of gold deposits of all kinds.
