FROGS AND TOADS, common name for amphibians that make up the order Anura (or Salientia). The order is usually divided into 22 families, based primarily on skeleton and teeth. The differences between frogs and toads are mainly superficial, with the name frog usually applied to smooth-skinned, mostly aquatic species, and toad to the rough-skinned, mostly terrestrial species. Anurans are native to all parts of the world except Antarctica. The greatest variety is found in tropical areas where the differences between frogs and toads are even harder to determine, and some species qualify as either.
Physical Characteristics top Anurans range in size from 12 mm (0.5 in) to nearly 300 mm (nearly 1 ft) in length. Typical adults are tailless, with long, powerful hind limbs that enable them to hop or leap, and webbed feet, helping them to swim, burrow, or glide through the air. Anurans also have flat heads, external eardrums, bulging eyes that can rotate in almost any direction, and pupils that close down to a slit when exposed to bright light. All anurans have skin glands that secrete irritating toxins for defense against predators. The internal systems of frogs and toads are typical of most amphibians. In fact, all amphibians were originally known as batrachians, from the Greek word for frog

Toads and frogs often conjure up thoughts of wet places misty swamps and enchanted nights when mysterious calls rise from the water's edge. Although wetlands are crucial to their life cycle, these amphibians don't live exclusively in water. They often emerge from their aquatic homes to become land dwellers. Some hardy toads and frogs even spend their entire winter in the leaf litter of a forest floor or in a deep burrow below the frost line of an open grassland. Toads and frogs are collectively known as anuranstailless amphibians. The 14 species of toads and frogs found in Minnesota are grouped into three families: toads, treefrogs, and true frogs. All species within each family share similar features, but each individual species has its own unique breeding call, survival strategy, and environmental niche. Over thousands of years, Minnesota's toads and frogs have adapted to survive a wide range of conditions. By learning more about these amphibians, their habitats, and their survival methods, Minnesotans can better appreciate why we need to conserve the wetlands, grasslands, and forests where these fascinating animals live. Their presence is an indication that we are doing a good job of preserving wetland habitat and water quality. Conversely, when toads and frogs disappear, it could mean the ecosystems that sustain them are ailing. Back to top

STERN'S SPLENDOR S
OF THE RAIN FOREST
MICHIGAN, USA Home Page Bromeliads and orchids are the floral aristocrats of the rain forest. They display an incredible range of form and size and, when they bloom, an impressive palette of extraordinary colors. These plants are native to the tropical and subtropical areas of the Americas, the majority indigenous to South America. Most of them grow as air plants on the trunks and branches of trees. Some species wrap their roots around porous rocks, while others, such as the pineapple and "earth stars," grow in the soil. To obtain unusual and rare species, I recommend joining plant societies. These organizations promote plant and seed exchanges and provide information on the culture of these plants. PHOTO GALLERY VISIT: Orchids Tillandsias Bromeliads Greenhouse ...

Saving frogs and toads
Researchers around the world have discovered that populations of several species of toads and frogs have declined or completely vanished. This disappearance is thought to be the result of habitat loss and degradation, loss of atmospheric ozone, disease, increase in pollution, and overuse of pesticides. The northern cricket frog, which once inhabited extreme southern Minnesota, has not been documented anywhere in the state for several years. No one has a clear explanation for why this species, now considered endangered in Minnesota, has disappeared. The decline of spring peepers in the Twin Cities metropolitan area may be linked to the loss of forested wetlands. A Wisconsin study found this woodland species is more likely to breed in wetlands with forests nearby. Why worry about the loss of toads and frogs? In addition to being fascinating animals, these amphibians make up an integral part of the food web. Tadpoles eat large amounts of algae and plankton, storing excess nutrients that could otherwise put a wetland out of balance. Amphibians later emerge from the wetland, moving nutrients obtained in the aquatic environment onto land. Toads and frogs eat many insects and, in turn, are eaten by birds, mammals, fish, and reptiles. These amphibians are also indicators of environmental health or sickness. The permeable skin and dual life existence in both water and land make them highly vulnerable to pollution. The loss of toad and frog populations in various areas of the world is a signal that healthy ecosystems may be imperiled.

Links Introduction The Tennessee Amphibian Monitoring Program (TAMP) is a volunteer-based, multi-agency effort to assess the current status of amphibians (frogs, toads, and salamanders) across our state, with the goal of learning where they live and how they are doing. The TAMP is sponsored by the Tennessee Wildlife Resources Agency (TWRA) and the Center For Environmental Education at Middle Tennessee State University. Participation in the Tennessee Amphibian Monitoring Program is voluntary and is open to all interested persons, old and young alike. Barking Treefrog Photo by A. Peterson, TWRA Why the TAMP Was Established Frog Eggs Photo by David Duhl, TDEC In some high-elevation lakes of the Pacific Northwest it was recently shown that frog eggs allowed to develop in their native habitat were adversely affected by the amount of ultraviolet radiation present, while those that were shielded from UV light developed normally. Many populations of some montane (mountain habitat) frog species may have disappeared for this reason. This lends some credence to our concerns about holes in the ozone layer, and reminds us of the value of amphibians as environmental indicators.

Search TennesseeAnytime TN Wildlife Resources Agency Directory Help Center Amphibian Declines Natural extinctions and population fluctuations are a normal part of nature. Scientists have uncovered five mass extinctions throughout the history of earth. But the accelerated rate at which many species are now declining and disappearing is very alarming to the scientific community. It is believed we are now in the sixth mass extinction event; the first ever caused by the actions of a single species, humankind. During the past couple decades, scientists have become concerned that many of our amphibian populations are declining and some species have become extinct in areas of the world that are relatively undisturbed by man. Below are but a few examples of the many declines and extinctions of the past two decades: The golden toad ( Bufo periglenes ) was first discovered in the remote and pristine cloud forests of the Monteverde Preserve of Costa Rica in 1967. This toad was very unusual because it was sexually dimorphic (the sexes could easily be identified.) The last golden toad ever seen was in 1987 and they have now been declared extinct. The northern gastric brooding frog ( Rheobatrachus vitellinus ) of Australia was discovered in 1984 and last seen in the wild in 1985 following the fate of the closely related gastric brooding frog ( Rheobatrachus silus that was discovered in Australia in 1973 and had disappeared by 1981. These unusual frogs brooded their young in their stomachs and were of interest to the scientific and medical community as they ceased producing hydrochloric acid in the stomach when they were brooding young frogs.

Toads And Frogs Puzzle
The Toads And Frogs Puzzle is also known under the names of Hares and Tortoise and Sheep and Goats . With no animals at hand, it can be played with two kinds of coins. The following names still reflect on the essence of the activity: Hop, Skip, Jump and Traffic Jam N frogs are placed on N successive positions on the left of a string of squares; M toads occupy M rightmost squares. On the whole, there are M + N + 1 squares, so that just one square remains unoccupied. Frogs only move rightward; toads move leftward. Every move is either a S lide to the nearby square or a J ump over one position, which is allowed only if the latter is occupied by a fellow of a different kind. In any case, no two animals are allowed in the same square. The goal is to move toads into M leftmost positions and the frogs into N rightmost positions. The number of toads and frogs can change between 1 and 5. Originally, N = M = 3.

Toads And Frogs Puzzle
in 2D
Here's a 2-dimensional variant of the Toads and Frogs puzzle. The rules are virtually identical. Frogs only move rightward or downward, toads can only move leftward and upward. A piece can jump over another piece of a different kind, provided the square on which it lands is empty. The goal of the puzzle of course is to cause frogs and toads to swap their positions.

  • W.W.Rouse Ball and H.S.M.Coxeter, Mathematical Recreations and Essays , Dover, 1987 Alexander Bogomolny The puzzle is solved by the following observation. The middle vertical column may be looked at as a simple 1-dimensional puzzle. In the course of a successful solution of that puzzle, the empty square will eventually move over all squares in that column. (This is because all pieces will have to be moved from their original positions.) The row in which the empty square is located may be looked at as another 1-dimensional puzzle, this time horizontal. The process of solution of the vertical puzzle serves as an index into a sequence of horizontal puzzles that are solved successively.
