Through the wonders of close-up photography, this unique CD-ROM brings
students face-to-face with the inner workings of a freshwater pond, the myriad creatures
and plants that reside there, and the dynamic interactions that go on beneath the surface.
This disk features a library of reference information, images, illustrations, clip art, video
clips and more!

Section One provides a general overview of ecosystems in general and the pond
ecosystem in particular, and introduces the various life forms that reside there. These
include emergent and submerged rooted water plants, microscopic and small
macroscopic animals, aquatic insects, molluscs, amphibians, reptiles, birds and
mammals. Spring and fall overturns are explained and numerous links lead students to
images and text that round out their understanding.

Section Two delves into microscopic pond life in great detail, covering: the
different types of cells, eubacteria, cyanobacteria, euglenoids, diatoms, desmids,
dinoflagellates, flagellates, amoebas, ciliates, suctorians and green protists. Eye
stopping photographs of many examples accompany detailed information.

Section Three presents pond plants and information about how they grow and
reproduce, an what lives on and among them: larch, weeping willow, paper birch, poplar,
alder, jewelweed, ferns, mosses, phragmites, aromatic water lily, variable pond weed,
floating heart, submergent rooted plants, cardinal flower, sundew.

With more striking close-up photographs, Section Four presents the small
invertebrate life that is so plentiful amid the shallow water vegetation and pond sediments:
rotifers, gastrotrichs, hydras, flatworms, nematodes, bryozoans, microannelids,
cladocerans (water fleas), and microcrustaceans. Again, numerous links connect these
creatures to other members of the pond community.

Section Five introduces food chains and trophic levels, photosynthesizers,
herbivores, carnivores, omnivores and decomposers. In the process, the numerous pond
vertebrates—fish, amphibians, reptiles, birds and mammals—are reintroduced and
presented in depth, along with the microlife forms previously covered. Life styles, feeding
behavior, mating and reproduction, as well as their dependence on other pond life are
presented for the vertebrates.

Section Six provides Field Trip and Laboratory tips. Various classroom and field
projects, ways to collect and preserve specimens, how to calculate a diversity index,
safety considerations, etc.

Section Seven is a unique curriculum section that provides the means to link the
vast library of resources to key, curriculum-based science topics.

Can be used with either Windows or Mac. Color printer recommended.
System Requirements:
Windows 95 or higher, 16MB RAM. Sound card recommended.
Mac 7.5 or higher, 16MB RAM.

EXPLORING FRESHWATER COMMUNITIES--CD-ROM Order #CDR-1550.........$99.95
Lab Pack of 5 Order #CDR-1550-5.........$199.95

Combined IBM/MAC Format

This indispensable interactive CD-ROM is a complete resource for studying
freshwater biomes.

It provides a fascinating survey of the ecology of swamps, bogs, marshes,
wetlands, streams, ponds, lakes and the Everglades. There is even an introduction to
fish restoration and water pollution.

It also explores the various organisms commonly found associated with these
waters--fish, plankton, protozoa, aquatic insects, amphibians, reptiles, birds and plants,
and emphasizes their special adaptations, feeding habits and the complex interactions
among them.

This program is an instant curriculum-oriented encyclopedia, augmented with
printable diagrams and illustrations, superb photographs, video clips, informative text, lab
activities, and a Protists Culture Database--all on one CD-ROM.

The extensive library of illustrations and diagrams supplements those found in
textbooks.

The Protist Culture Database makes it easy to find over 125 protist genera, and
iIncludes morphologic characteristics, culture parameters and media formulations.

Printable lab activities and laboratory activity tips at the end of each section
help make your ecology labs and field trips more successful than ever before.

Recommended for use with popular biology texts such as Holt: Modern Biology,
Chapter 49, and Prentice Hall: Biology, Chapter 47.

CONTENT SAMPLE:

There are four major types of wetlands: marsh, swamp, fen and bog. Exact classification
is not always possible, since characteristics of more than one type often occur together. In fact,
wetland ecologists sometimes disagree on exactly what these names mean. Before looking at a
bog, in detail, let's briefly consider these four types of wetlands.

A marsh is defined as a wet, open, grassy area with a fluctuating, but always shallow,
water level. The water is either standing or slowly moving. The substratum, or bottom, consists
of mineral soils with or without organic matter.

Both dissolved oxygen and mineral nutrients in the water are present in ample supply.
As a result, marshes can support an abundance of living organisms. Dominant vegetation in
marshes consists of rushes, reeds, reedgrasses, and numerous floating and, in areas of open
water, submerged aquatic plants.

Trees and shrubs are present only near the edges and on small islands of land within the
marsh.

The Everglades region of Florida is a well-known wetland primarily marsh in character.
