Описание: Focuses on the diverse roles played by underwater plants. This book is divided into three parts: 10 thematic chapters, followed by 18 case studies, concluded by three integrative chapters. It covers topics ranging from macrophytes as fish food to macrophytes as mollusk and microbe habitat.

Описание: The topics range from macrophytes as fish food to macrophytes as mollusc and microbe habitat, making this of interest to aquatic ecologists as well as limnologists, ecosystem ecologists, microbial ecologists, fish biologists, and environmental managers.
Описание: A wide range of microbes are used directly in aquaculture as live feeds, probiotics, and in filtration systems. Aquatic microorganisms are therefore indispensable resources for growth of shellfish and finfish in natural aquatic ecosystems and in aquaculture.

Описание: This, the first review of the range of factors affecting the welfare of farmed flightless birds, focuses on the ostrich, emu and rhea. It discusses husbandry and management protocols at each stage of the farming process as well as their welfare implications.
Описание: The book begins with an introductory chapter followed by eleven case study chapters demonstrating the nexus between biodiversity, health, and sustainable development, and then a synthesis chapter clarifying the relevance of the case study findings to policy and academic discussions.

Описание: This study provides an overview of the roles that the biodiversity found in and around food and agricultural production systems play in the supply of ecosystem services. These range from provisioning services, such as the supply of food, fuel and fibre, to cultural services, including recreation and aesthetic enjoyment, and regulating services (e.g. pollination, carbon sequestration, pest control and nutrient cycling).
Biodiversity for Food and Agriculture corresponds to “the variety and variability of animals, plants and micro-organisms at the genetic, species and ecosystem levels that sustain the ecosystem structures, functions and processes in and around production systems, and that provide food and non-food agricultural products.” The study considers a range of ecosystem services across the “provisioning”, “regulating”, “supporting”, “habitat” and “cultural” categories.
The examples presented in the report show that the benefits that a given food and agricultural production unit (i.e. farm, fish farm, forest stand, fishery or livestock holding) gains from biodiversity generally come both from within and from outside the production unit. They also show that the biodiversity present in and around food and agricultural production systems often provides ecosystem services whose benefits are felt far beyond the food and agriculture sector (and in some cases far away in geographical terms).
