Book excerpt: "It's up to every single one of us to do our bit for wildlife, however small our gardens, and The Butterfly Brothers know just how that can be achieved." Alan Titchmarsh Join the rewilding movement and share your outdoor space with nature. We all have the potential to make the world a little greener. Wild Your Garden, written by Jim and Joel Ashton (aka "The Butterfly Brothers"), shows you how to create a garden that can help boost local biodiversity. Transform a paved-over yard into a lush oasis, create refuges to welcome and support native species, or turn a high-maintenance lawn into a nectar-rich mini-meadow to attract bees and butterflies. You don't need specialist knowledge or acres of land. If you have any outdoor space, you can make a difference to local wildlife, and reduce your carbon footprint, too. "Wildlife gardening is one of the most important things you can do as an individual for increasing biodiversity and mitigating the effects of climate change. From digging a pond to planting a native hedge, the Butterfly Brothers can help you every step of the way." Kate Bradbury

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 Pond Ecosystems of the Indian Sundarbans written by Sourav Das and published by Springer Nature. This book was released on 2021-10-18 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims to give a holistic overview of the pond ecosystem of Indian Sundarbans. Due to climate change, the Indian Sundarbans faces several challenges. With rising sea levels, islands are disappearing and the increasing salinity in the water and soil has severely threatened the health of mangrove forests and the quality of fresh water, soil and crops. Additionally, there have been serious disturbances to hydrological parameters in the lotic as well lentic ecosystems. This book provides new insights into lentic ecosystem-oriented research in the deltaic ecosystem of GBM-I (Ganga-Brahmaputra-Meghna, Indian Delta). The major findings from various research works are brought together, and the gaps and future possible ways forward are outlined. The book addresses the SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action) and SDG 14 (Life below Water), with a focus on the ecosystem services of ponds in the Indian Sundarbans. Despite there being many studies on riverine water, ground water and mangrove ecosystems of the Indian Sundarbans, this book offers new insights into the pond ecosystem of the Indian Sundarbans. The outcomes from this book can be utilized by researchers from the inland fisheries sector, environmental managers, professionals, and those who seek to develop ways for making pond ecosystems sustainable.

Download or read book Bottom Soils Sediment and Pond Aquaculture written by Claude E. Boyd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquaculture pond managers measure water-quality variables and attempt to maintain them within optimal ranges for shrimp and fish, but surprisingly little attention is paid to pond soil condition. Soil-water interactions can strongly impact water quality, and soil factors should be considered in aquaculture pond management. The importance of soils in pond management will be illustrated with an example from pond fertilization and another from aeration. Pond fertilization may not produce phytoplankton blooms in acidic ponds. Total alkalinity is too low to provide adequate carbon dioxide for photosynthesis, and acidic soils adsorb phosphate added in fertilizer before phytoplankton can use it. Agricultural lime stone application can raise total alkalinity and neutralize soil acidity. The amount of limestone necessary to cause these changes in a pond depends on the base unsaturation and exchange acidity of the bottom soil. Two ponds with the same total alkalinity and soil pH may require vastly different quantities of limestone because they differ in exchange acidity. Aeration enhances dissolved oxygen concentrations in pond water and permits greater feed inputs to enhance fish or shrimp production. As feeding rates are raised, organic matter accumulates in pond soils. In ponds with very high feeding rates, aeration may supply enough dissolved oxygen in the water column for fish or shrimp, but it may be impossible to maintain aerobic conditions in the surface layers of pond soil. Toxic metabolites produced by microorganisms in anaerobic soils may enter the pond water and harm fish or shrimp.
