Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks.

Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections:

• Biology, Population Dynamics and Recruitment

A comprehensive, best-selling guide to more than 3,000 snake species for fans of snakes, snake owners, and students now in an updated second edition produced in association with the Smithsonian Institution.

Get to know more than 3,000 snakes from around the world, from the familiar, massive Green Anaconda to the deadly Tropical Rattlesnake, the Reticulated Python, Red-Spitting Cobra, Puff Adder, Gaboon Viper, and more. Learn about the lesser-known dainty Leopard Snake, whose bright markings trick predators and often humans into thinking it is a deadly viper.

"Snake" uses gorgeous,...

The Malagasy region contains one of the most extraordinary concentrations of biodiversity in the world. Its recognition as a zoogeographic region in its own right has recently been confirmed, and, all taxa combined, the region was found to hold the second most distinct assemblage of vertebrates in the world after the Australian region, despite being the smallest of them all.

This new field guide from the Helm Field Guides series covers the whole of the Malagasy region, which comprises the unique island of Madagascar and the various islands and archipelagos of the Indian Ocean,...

Biological diversity - or biodiversity - is the degree of variation of life within an ecosystem. It is a relatively new topic of study but has grown enormously in recent years. Because of its interdisciplinary nature the very concept of biodiversity is the subject of debate amongst philosophers, biologists, geographers and environmentalists.

The Routledge Handbook of Philosophy of Biodiversity is an outstanding reference source to the key topics and debates in this exciting subject. Comprising twenty-three chapters by a team of international contributors the...

Paddlefish have become of increasing interest to the aquaculture community in recent years, particularly as a potential new source of seafood and caviar. Native to North America, paddlefish show great promise both domestically and internationally as a commercially viable farmed species.

Paddlefish Aquaculture examines all aspects of the biology and culture of these fish, exploring their physiology, production, end products and the economics underlying a successful paddlefish operation. Chapters specifically cover paddlefish biology, propagation and early culture techniques,...

Bovids are a diverse group of ruminant mammals that have hooves and unbranched hollow horns. Bovids of the World is the first comprehensive field guide to cover all 279 bovid species, including antelopes, gazelles, cattle, buffaloes, sheep, and goats. From the hartebeest of Africa and the takin of Asia to the muskox of North America, bovids are among the world's most spectacular animals and this stunningly illustrated and easy-to-use field guide is an ideal way to learn more about them.

The guide covers all species and subspecies of bovids described to date. It features more...

The increasing deployment of bioenergy frequently raises issues regarding the use of land and raw materials, infrastructure and logistics. In light of these sometimes conflicting interests Advances in Bioenergy provides an objective and wide-ranging overview of the technology, economics and policy of bioenergy.

Offering an authoritative multidisciplinary summary of the opportunities and challenges associated with bioenergy utilization, with international researchers give up-to-date and detailed information on key issues for biomass production and conversion to energy.

Biomass currently accounts for about fifteen per cent of global primary energy consumption and is playing an increasingly important role in the face of climate change, energy and food security concerns.

Handbook of Bioenergy Crops is a unique reference and guide, with extensive coverage of more than eighty of the main bioenergy crop species. For each it gives a brief description, outlines the ecological requirements, methods of propagation, crop management, rotation and production, harvesting, handling and storage, processing and utilization, then finishes with selected...
