Essential Fish Biology provides an introductory overview of the functional biology of fish and how this may be affected by the widely contrasting habitat conditions within the aquatic environment. It describes the recent advances in comparative animal physiology which have greatly influenced our understanding of fish function as well as generating questions that have yet to be resolved. Fish taxa represent the largest number of vertebrates, with over 25,000 extant species. However, much of our knowledge, apart from taxonomy and habitat descriptions, has been based on relatively few of them, usually those which live in fresh water and/or are of commercial interest. Unfortunately there has also been a tendency to base our interpretation of fish physiology on that of mammalian systems, as well as to rely on a few type species of fish. This accessible textbook will redress the balance by using examples of fish from a wide range of species and habitats, emphasizing diversity as well as recognizing shared attributes with other vertebrates.

Ponds and small lakes support an extremely rich biodiversity of fascinating organisms. Many people have tried pond-dipping and encountered a few unfamiliar creatures, such as dragonfly nymphs and caddisfly larvae. However, there is a far richer world of microscopic organisms, such as diatoms, desmids and rotifers, which is revealed in this book. Anyone with access to a microscope can open up this hidden dimension. Identification keys are provided so that readers can identify, explore and study this microscopic world. There are also many suggestions of ways in which readers can then make original contributions to our knowledge and understanding of pond ecology. The book not only explores the fascinating world of the creatures within ponds and their interactions, but also explains the many ways in which ponds are important in human affairs. Ponds are being lost around the world, but they are a key part of a system that maintains our climate. In the face of climate change, it has never been more important to understand the ecology of ponds. Includes keys to: A – Traditional key to kingdoms of organisms; B – Contemporary key to kingdoms of organisms; C – Pragmatic key to groups of microorganisms; D – Algae visible, at least en masse, to the naked eye; E – Periphyton, both attached to surfaces and free living; F – Protozoa; G- Freshwater invertebrates and; H – Common phytoplankton genera in ponds.

Owning a pond can be an incredible experience filled with hours of fun and relaxation. Like many things, ponds need maintenance and care to keep them in good condition. They are isolated ecosystems surrounded for the most part by very unnatural land uses. The impact on them is fast and builds. This handbook is designed to give the average pond owner the knowledge and skills needed to manage the pond to reduce excessive aquatic plant growth and support a strong fishery. This will be accomplished through evaluating the pond using measurable chemical and physical factors and then improving the condition of the pond through techniques proven in the field.
