Life in a pond is exciting. Birds, bugs, and shrews skitter across the surface. Turtles and fish zip along under the water’s surface. Beavers, herons, and others make themselves at home by the pond’s edge. In this book, readers in grades 3-5 will discover how these animals survive and thrive in freshwater pond biomes around the world. This NGSS-aligned series is packed with interesting facts and vivid photos that introduce readers to a variety of land and water animals. Each book includes a glossary, comprehension questions, and an activity for home or the classroom.
Introduces readers to the intriguing world of freshwater life.
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

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.
This friendly, practical guide includes everything you need to know to pick up a spade, put in a pond and help wildlife flourish right outside your back door. Ponds are vital oases for nature. They are nursery grounds, feeding stops and bathing spots. They are genetic superhighways and vibrant ecosystems each brimming with life, interactions and potential. And they are for everyone. In The Wildlife Pond Book, Jules Howard offers a fresh perspective on ponds and encourages gardeners to reach for a garden spade and do something positive to benefit our shared neighbourhood nature. As well as offering practical tips and advice on designing, planting up and maintaining your pond, Jules encourages readers to explore the wildlife that colonises it with a torch, a microscope or a good old-fashioned pond-dipping net. With a foreword by award-winning wildlife-gardening author, Kate Bradbury, this helpful new guide includes a section outlining the hundreds of organisms that may turn up in your pond and is packed with creative ideas that have been tried and tested by author Jules Howard, an avid pond-builder, prolific pond-dipper and passionate voice for freshwater conservation for more than fifteen years. So, no matter how big your outdoor space is, The Wildlife Pond Book is the guide you need to create your very own haven for nature.
Discusses the seasons and characteristics of a freshwater pond, including how plants, animals, and humans learn to adapt to this environment.

The most complete owner's manual for keeping all types of freshwater and saltwater fish in indoor tropical and coldwater aquariums and outdoor ponds. Choose the right fish for any water temperature--tropical or coldwater--and for all types of environments, including indoor aquariums or outdoor ponds. Know the difference between keeping saltwater fish and freshwater fish, including differences in aquarium setups, and feeding and caring for your pet fish. Learn to tell whether your fish are healthy and find out everything you need to breed them successfully. The Encyclopedia of Aquarium and Pond Fish contains a huge photographic color reference directory of more than 800 of the most popular fish, not only showing you what they look like, but also giving you key information you need, such as how big they will grow, whether they integrate with different fish, what food they eat, and what water type and temperature they prefer.
The efficient and profitable production of fish, crustaceans, and other aquatic organisms in aquaculture depends on a suitable environment in which they can reproduce and grow. Because those organisms live in water, the major environ mental concern within the culture system is water quality. Water supplies for aquaculture systems may naturally be oflow quality or polluted by human activity, but in most instances, the primary reason for water quality impairment is the culture activity itself. Manures, fertilizers, and feeds applied to ponds to enhance production only can be partially converted to animal biomass. Thus, at moderate and high production levels, the inputs of nutrients and organic matter to culture units may exceed the assimilative capacity of the ecosystems. The result is deteriorating water quality which stresses the culture species, and stress leads to poor growth, greater incidence of disease, increased mortality, and low produc tion. Effluents from aquaculture systems can cause pollution of receiving waters, and pollution entering ponds in source water or chemicals added to ponds for management purposes can contaminate aquacultural products. Thus, water quality in aquaculture extends into the arenas of environmental protection and food quality and safety. A considerable body of literature on water quality management in aquaculture has been accumulated over the past 50 years. The first attempt to compile this information was a small book entitled Water Quality in Warmwater Fish Ponds (Boyd I 979a).
This is an original and exciting look at the fascinating natural world of ponds and rivers. Stunning real-life photographs of fish, water beetles, frogs, underwater weeds, and more offer a unique view of the natural history of plants and animals that live in and around freshwater habitats.
