Book Description
From single-celled organisms in Black Sea sand to endemic cave crustaceans, from mountain glacial relict insects to the most diverse bird fauna in Europe, the fauna of Bulgaria has been a subject of study for more than a century. This is the first English language survey of all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues.

Book Description
Sedimentary habitats cover the vast majority of the ocean floor and constitute the largest ecosystem on Earth. These systems supply fundamental services to human beings, such as food production and nutrient recycling. It is well known that meiofauna are an abundant and ubiquitous component of sediments, even though their biodiversity and importance in marine ecosystem functioning remain to be fully investigated. In this book, the meiofaunal biodiversity trends in marine habitats worldwide are documented, along with the collection of empirical evidence on their role in ecosystem services, such as the production, consumption, and decomposition of organic matter, and energy transfer to higher and lower trophic levels. Meiofaunal activities, like feeding and bioturbation, induce changes in several physico-chemical and biological properties of sediments, and might increase the resilience of the benthic ecosystem processes that are essential for the supply of ecosystem goods and services required by humans. As a key component of marine habitats, the taxonomical and functional aspects of the meiofaunal community are also used for the ecological assessment of the sediments’ quality status, providing important information on the anthropogenic impact of benthos.

Book Description
This is a comprehensive treatise on meiobenthology, the science of small animals which live, often disregarded even by zoologists, in huge numbers in all aquatic sediments. Covering all the scientific literature on the subject, particular emphasis is placed on ecological and systematic aspects. After a survey of the biotope conditions and important methods, the animals are introduced in a systematic account. This is followed by a report on the meiobenthos in relevant biotopes. The book concludes with an analysis of the productive role and the position of meiofauna in the food web and perspectives for future research.

Book Description
Recent studies on diverse aspects of the biology of clitellate works (oligochaetes and leeches) are found in the Proceedings of the most recent International Symposium on Aquatic Oligochaete Biology - from development to population dynamics and from ultrastructure to evolution. The majority of the contributions, which have a very broad geographic scope, are investigations of the biology and ecology of oligochaete works in natural and polluted waters.

Book Description
The book traces the ways in which terrestrial animals have evolved from aquatic ancestors and discusses the means by which they are adapted to life on land. The most important physiological adaptations are those involving salt and water balance, the excretion of nitrogen, reproductive mechanisms and the sense organ and these are given priority. Evidence from fossil history is combined with that from the ecology and physiology of present-day species to assess the probable routes along which various evolutionary lines had moved on to land. Individual chapters are concerned with specific animal groups and emphasis is placed on comparisons of physiological mechanisms between closely related animals before attempting wider generalisations. The book closes with a brief account of the recolonisation of the sea and fresh waters by terrestrial animals.
