THE MICROSCOPIC POND

In a pond there is a vast and rich diversity of life forms hidden from our eyes,
since a healthy pond may harbor from 5OO to 1,OOO different species of microscopic
organisms. The evironment of a pond is ever-changing, often representative of
evolutionary history, and no two ponds are ever exactly alike.

This exquisitely photographed program introduces students to both the
microscopic plant and animal life of a pond. Various groups of algae are discussed and
illustrated, including desmids, Pediastrum, Pithophora, Spyrogyra, Volvox, Nostac,
calothrix, Bacillariophyseae, Dinophyseae, and amoebas, including Amoeba proteus,
Arcella, the testaceans, and many others. With only a few exceptions, all of the
organisms in this program were photographed live, and in many cases while in motion.

In three parts: Part I Monerans and Protists; Part II Animal-like Protists and
Green Algae; Part III Metazoans. 8O frames each, detailed guide. Available in three
formats: video conversions, slides in trays with cassettes, filmstrips with cassettes.

CONTENT SAMPLE:

210 Among the most numerous arthropods in ponds are the microscopic
crustaceans. One very abundant group is the cladocerans, as represented here by Daphnia,
often called the water flea. Note the antennae, musculature, intestine, and eggs.. . .

212 The body of a cladoceran is enclosed in a two-part, chitinous shell which is
open in the front. The beating appendages inside the shell create a current which draws water
and with it filterable food to the body. . . .

213 The eggs within the body of this cladoceran will go through about 15 moults
between hatching and their adult form.

REVIEWS: "Highly recommended...achieves a great blend of facts and concepts....
Overall, the planning that went into this set is obvious, and the excellent results make
the price modest." Science Books and Films.

"This program will be most appreciated by secondary-level biology students...[who] will
appreciate the superb quality of the visuals and will profit from the slower-paced...slide format."
Media Review.

"...a substantial program incorporating good photography, interesting script, and current
taxonomy... Recommended for college libraries." Choice.

A CLOSER LOOK AT PONDLIFE---CD-ROM Order #CDR-1565....$79.95
Lab Pack of 5 Order #CDR-1566....$159.95
Library Pack of 20 Order #CDR-1567....$559.95
Network Version (single server, one building) Order #CDR-1567N....$239.95

New 1999
Combined IBM/MAC Format

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.

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.
