Received: 27 August 2018; Accepted: 26 September 2018; Published: 30 September 2018 Abstract: Dike-ponds have experienced significant changes in the Pearl River Delta region over the past several decades, especially since China’s economic reform, which has seriously affected the construction of ecological environments. In order to monitor the evolution of dike-ponds, in this study we use multi-source remote sensing images from 1978 to 2016 to extract dike-ponds in several periods using the nearest neighbor classification method. -

Limnology of Ponds in the Kissimmee Prairie
Limnology of Ponds in the Kissimmee Prairie Tim Kozusko Environmental Management, United Space Alliance, 8550 Astronaut Blvd., USK-T28, Cape Canaveral, FL 32920 E-mail: [email protected] John A. Osborne UCF Department of Biology, 4000 Central Florida Blvd., Orlando, FL 32816-2368 Paul Gray Audubon of Florida, 100 Riverwoods Circle, FL 33857 ABSTRACT We studied the physicochemical features of three ponds in the Kissimmee Prairie, Okeechobee County, Flor- ida, between January and August 1997, and May and August 1998. Data collected included pH, specific con- ductance, water temperature and depth, turbidity, water color, alkalinity, tannin, dissolved oxygen, and concentrations of nitrogen and phosphate. We found the ponds to be acidic, poorly buffered, moderate to high in water color, and low in mineralized nitrogen and phosphorus. There were statistically significant differences in water chemistry between the inner zones of ponds and the outermost wet prairie zones. Water in the wet prairie zones had significantly lower pH, higher specific conductivity, and greater water color and tannin con- centrations than did water in the inner zones of ponds.

Goldman. 1994. Limnology. 2nd edition. McGraw-Hill Co., New York, New York, USA.) Limnology is the study of fresh or saline waters contained within continental boundaries. Limnology and the closely related science of oceanography together cover all aquatic ecosystems. Although many limnologists are freshwater ecologists, physical, chemical, and engineering limnologists all participate in this branch of science. Limnology covers lakes, ponds, reservoirs, streams, rivers, wetlands, and estuaries, while oceanography covers the open sea. Limnology evolved into a distinct science only in the past two centuries, when improvements in microscopes, the invention of the silk plankton net, and improvements in the thermometer combined to show that lakes are complex ecological systems with distinct structures. Today, limnology plays a major role in water use and distribution as well as in wildlife habitat protection. Limnologists work on lake and reservoir management, water pollution control, and stream and river protection, artificial wetland construction, and fish and wildlife enhancement. An important goal of education in limnology is to increase the number of people who, although not full-time limnologists, can understand and apply its general concepts to a broad range of related disciplines. A primary goal of Water on the Web is to use these beautiful aquatic ecosystems to assist in the teaching of core physical, chemical, biological, and mathematical principles, as well as modern computer technology, while also improving our students' general understanding of water - the most fundamental substance necessary for sustaining life on our planet. -
Homeowners Guide to Protecting Ponds and Wetlands
Homeowners Guide to Protecting Ponds and Wetlands Weston has several small ponds throughout town. Most of these ponds were originally man-made either by building a dam (i.e. Hobbs Pond and College Pond) or by dredging an area along a stream. Weston’s ponds provide habitat for numerous birds, fish, turtles, frogs, and mammals. Because these ponds are often shallow, controlling aquatic plants from over-taking them can be a challenge. Several Weston homeowners have hired professionals to prepare and implement pond management programs. These programs often involve hand removal and/or chemical treatment to control nuisance or invasive aquatic plants. However, it’s important for pond abutters to know that they too directly affect pond health and water quality. This brochure lists several ways homeowners can help protect Weston’s ponds and wetlands. 1. Nature likes it Messy Some people want to “clean up” nature to create a park like appearance. However, wildlife often needs thick tangles of undergrowth, leaf litter, and deadwood to survive. Aquatic plants are a vital part of any healthy pond and wetland ecosystem. Plants and algae provide many benefits to the pond: roots help to prevent muddy water by stabilizing the pond bottom and banks. Pond plants use nutrients that may be taken up by nuisance algae. The stems, roots, and leaves of pond plants serve as important wildlife habitat for small pond animals such as dragonfly nymphs, tadpoles, and crayfish. If you are concerned that there are too many nuisance plants or algae growing in your pond, the law requires that you speak to the Conservation Commission prior to doing any vegetation removal or chemical treatments within or near the pond. -
