This book brings together leading conservation practitioners to reflect on their response to the current global biodiversity crisis, through the lens of island species recovery and management. Initial chapters cover the biological understanding of small population biology and the growing threat of invasive species, while subsequent chapters discuss the management of these threats and the complexity of leading projects within a dynamic and still relatively unknown system. Multiple case studies from islands worldwide illustrate key points, allowing readers to draw on the first-hand practical experience of experienced professionals. This resource will be invaluable to both current and future conservation professionals, helping them to go beyond disciplinary 'comfort zones' and develop, manage and lead projects over extensive timeframes in a way that brings others with them on the journey.

Gills of healthy fishes are their lifeline to meet the challenges arising from their changing environment: oxygen gradient, alkalinity, temperature fluctuations and the added pollutants. The diverse and ever changing aquatic environment has a major impact on the organization of various organ-systems of fishes. This book contains seventeen chapters covering bony fishes which are focal to the current study. The chapters primarily cover fish respiration but also include osmoregulation, these being the two main functions of gills. Concurrently, cardiorespiratory synchronization has been well addressed. It is hoped that this book with its broad coverage and well-supported with illustrations will not only infuse interest in readers but merit a permanent place on the shelves of ichthyological literature.

Offers an integrated presentation of the microbial, agronomic and recycling aspects of soil faunal potentials, emphasizing agricultural ecosystems and furnishing methods for modelling food webs. The text covers morphology, reproduction, abundances, basic requirements, competition, predation, parasitism, nutrient cycling and phytopathological interactions, soil physics and agricultural management, plus methods to quantify soil faunal groups.
