Avian Biology is a collection of papers that deals with biological aspects of birds such as their classification and habitat behavior. One paper reviews how birds are classified through practical systematics, study of fossils, and some of the problems encountered in the arrangement of major groups. Another paper discusses the origin and evolution of birds from their reptilian predecessors to their current evolutionary rates. Evolutionary rates vary depending on access to new habitats; if the environment is static, evolutionary rates can also slow down. One author discusses the inter-relations of sea birds with their marine environment, including coastal areas and the biological properties of the surface water. Another author describes the biology of desert birds relating to nomadism behavior and physical adaptations especially to the arid environment. The author also describes the cooling mechanism of these desert birds. Another paper evaluates the ecological aspect of behavior that includes foraging, habitat selection, mating, and flocking cohesion. Avian biologists, zoologists, and readers who have a general interest in birds will find this book useful.

The literature of Finland is bilingual, with lively and extensive traditions in both Finnish and Swedish. This history covers both literary traditions in detail. The volume?s first section, on Finnish-language literature, consists of a series of connected chapters by leading authorities within the field. It opens with a consideration of the folk literature in Finnish that flourished during the Middle Ages and then examines the more recent history of Finnish-language literature, with special emphasis placed on writings from the nineteenth and twentieth centuries. The second part of the book provides an examination of Finland?s Swedish-language literature from the late fifteenth century through the early nineteenth century. Subsequent chapters trace developments in Finland?s Swedish-language literature during the nineteenth and twentieth centuries. A survey of children?s literature?from both the Finnish- and Swedish-language traditions?concludes this exceptionally thorough volume.
While deforestation continues at an alarming rate around the world, discussions on the range of underlying causes continue. The premise is that studying successful transitions from deforestation to sustainable forestry ex post in Finland can provide novel insights into how deforestation in the tropics might be reduced in the future. Our fundamental question here is why Finland succeeded to stop deforestation for a century ago and why not the same is feasible in the contemporary tropical countries? This book presents a novel integrated theory within which this case study on Finland and contemporary modeling of underlying causes of tropical deforestation are developed. Finland remains the worl...

In this very personal book, Mead explains on the basis of more than half a century's experience how his interests in Finland developed in parallel with its transformation from a pre-war agrarian economy to a modern welfare state with an advanced technological base.
