Book excerpt: 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.
Download or read book Fresh Pond written by Jill Sinclair and published by MIT Press. This book was released on 2009-02-13 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of Fresh Pond Reservation—onetime summer retreat for wealthy Bostonians, center of the nineteenth-century ice industry, and stomping grounds for Harvard students—told through photographs, maps and plans, and stories. Fresh Pond Reservation, at the northwest edge of Cambridge, Massachusetts, has been described as a “landscape loved to death.” Certainly it is a landscape that has been changed by its various uses over the years and one to which Cantabridgeans and Bostonians have felt an intense attachment. Henry James returned to it in his sixties, looking for “some echo of the dreams of youth,” feeling keenly “the pleasure of memory”; a Harvard student of the 1850s fondly remembered skating parties and the chance of “flirtation with some fair-ankled beauty of breezy Boston”; modern residents argue fiercely over dogs being allowed to run free at the reservation and whether soccer or nature is a more valuable experience for Cambridge schoolchildren. In Fresh Pond, Jill Sinclair tells the story of the pond and its surrounding land through photographs, drawings, maps, plans, and an engaging narrative of the pond's geological, historical, and political ecology. Fresh Pond has been a Native American hunting and fishing ground; the site of an eighteenth-century hotel offering bowling, food and wine, and impromptu performances by Harvard men; a summer retreat for wealthy Bostonians; a training ground for trench warfare; a location for picnics and festivals for workers and sporting activities for all. The parkland features an Olmsted design, albeit an imperfectly realized one. The pond itself—a natural lake carved out by the retreating Ice Age about 15,000 years ago—was a center of the nineteenth-century ice industry (disparaged by Thoreau, writing about another pond), and still supplies the city of Cambridge with fresh drinking water. Sinclair's celebration of a local landscape also alerts us to broader issues—shifts in public attitudes toward nature (is it brutal wilderness or in need of protection?) and water (precious commodity or limitless flow?)—that resonate as we remake our relationship to the landscape.

This book was released on 1994-01-26 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: You?ll learn strategies and tactics that can be used to improve production and efficiency in the propagation of fingerlings in fertilized hatchery ponds. This book covers the production of a variety of fish, as well as shrimp, and provides a framework for a systems approach to management decisionmaking. Chapters present information that can be used to improve ecological efficiencies and the economics of production. Strategies and Tactics for Management of Fertilized Hatchery Ponds explains the systems approach to management. In the future, the most effective hatchery managers will base management decisions on information that is site- and pond-specific. This book provides you with needed information on organic and inorganic fertilizer materials; dynamics of water quality; pond filling schedules; biological control of problem organisms; fingerling production of walleye, striped bass, paddlefish, largemouth bass, and others. Readers find solutions to several common problems and learn about the processes needed to solve others. Chapters help answer questions important to the success and effectiveness of management of fertilized hatchery ponds such as: What kinds or sources of nutrients should be purchased? How much time and water are needed before larvae are stocked? What density and age of fish should be stocked? How can a satisfactory quality of larvae and environmental variables be achieved so that fish survive stocking and initiate normal feeding and growth? Has the initial survival and growth been satisfactory, or should the pond be drawn down and restocked? What kind and how much fertilizer should be added to a given pond? This book provides you with information essential for making hatchery ponds as effective and efficient as possible. Whether you?re a fish hatchery manager, student of aquaculture, or agency or academic researcher involved in hatchery management, you will find Strategies and Tactics for Management of Fertilized Hatchery Ponds an indispensable guide for your daily work and studies.

Download or read book Pond Conservation in Europe written by Beat Oertli and published by Springer Science & Business Media. This book was released on 2010-09-24 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ponds are an exceptional freshwater resource around the world and represent thirty percent of the global surface area of standing water. Furthermore, the millions of ponds which exist exhibit a particularly high biodiversity and have a high potential for ecosystem functions and services. Despite these impressive features, ponds face many threats from a variety of human activities and receive little or no protection under European and national legislation. Consequently, there is an urgent need to protect, consolidate and increase the pond resource in Europe. In order to achieve these objectives, the European Pond Conservation Network (EPCN) was launched 2004 in Geneva. Its aim is to promote the awareness, understanding and conservation of these small water bodies in the European landscape. This volume of “Developments in Hydrobiology” presents a selection of 31 papers presented during EPCN conferences held in 2006 in France (Toulouse) and in 2008 in Spain (Valencia). They represent a diverse collection of themes from across the continent and North Africa and present new and original insights into topics as wide ranging as pond biodiversity; human disturbance; landscape ecology; ecological assessment and monitoring; practical management measures; ecological restoration; hydrology and climate change; invasive species and threatened species.

Download or read book The Bio Integrated Farm written by Shawn Jadrnicek and published by Chelsea Green Publishing. This book was released on 2016 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bio-Integrated Farm is a twenty-first-century manual for managing nature's resources. This groundbreaking book brings "system farming" and permaculture to a whole new level. Author Shawn Jadrnicek presents new insights into permaculture, moving beyond the philosophical foundation to practical advanced designs based on a functional analysis. Holding his designs to a higher standard, Jadrnicek's components serve at least seven functions (classical permaculture theory only seeks at least two functions). With every additional function a component performs, the design becomes more advanced and saves more energy. A bio-integrated greenhouse, for example, doesn't just extend the season for growing vegetables; it also serves as a rainwater collector, a pond site, an aquaponics system, and a heat generator. Jadrnicek's prevalent theme is using water to do the work. Although applicable in many climates, his designs are particularly important for areas coping with water scarcity. Jadrnicek focuses on his experience as farm manager at the Clemson University Student Organic Farm and at his residence in the foothills of the Blue Ridge Mountains. These locations lie at the cooler northern edge of a humid subtropical climate that extends west to the middle of Texas and north along the coast to New Jersey. He has created permaculture patterns ranging from raising transplants and field design to freshwater prawn production and composting. These patterns have simplified the operation of the 125-share CSA farm while reducing reliance on outside resources. In less time than it takes to mow his two-acre homestead, Jadrnicek is building a you-pick fruit farm using permaculture patterns. His landscape requires only the labor of harvesting, and the only outside input he buys is a small amount of chicken feed. By carefully engaging the free forces of nature--water, wind, sunlight, convection, gravity, and decomposition--Jadrnicek creates sustenance without maintenance and transforms waste into valuable farm resources. The Bio-Integrated Farm offers in-depth information about designing and building a wide range of bio-integrated projects including reflecting ponds, water-storage ponds, multipurpose basins, greenhouses, compost heat extraction, pastured chicken systems, aquaculture, hydroponics, hydronic heating, water filtration and aeration, cover cropping, and innovative rainwater-harvesting systems that supply water for drip irrigation and flushing toilets.

Download or read book The Ecology and Behavior of Amphibians written by Kentwood D. Wells and published by University of Chicago Press. This book was released on 2010-02-15 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.
