SALT MARSHES--A SPECIAL RESOURCE Video order #FV-1017V.......$79.95

A scientifically accurate but simple and relatively nontechnical presentation that
details the intricacies of this special biome. Topics include: major grasses and flowering
plants, lavish food production capacity, invertebrates, vertebrates, impact of man,
economic importance, aesthetic and recreation considerations. 2 parts, detailed 27 page
guide. Video or filmstrips.

CONTENT SAMPLE:

64. From a biological standpoint, acre for acre, salt marshes are among the most
productive areas on earth because of the tremendous quantity of grasses and the availability of
minerals and nutrients from the sea.

65. Light energy, from the sun, is captured by the grasses and converted to food energy
by photosynthesis. It has been estimated that one acre of salt marsh, in a year, can produce up
to ten tons of organic matter.

REVIEWS:

**** "RECOMMENDED FOR PURCHASE WITHOUT RESERVATION." Media Review

"Highlighted by unobstructed close-ups of the plants and animals that reside in these
vanishing spots, the filmstrips are guided by a welcome narration that explains...these
remarkable regions.... Will build an appreciation for these singular environments among high
school students." Booklist.

"...an excellent introduction to the salt marsh...suitably paced for serious study."

FRESHWATER AND SALT MARSHES Video order #SS-1090V........$79.95

Describes and illustrates the various types of marshes, how marshes are
formed, and the plants and animals common to these very fertile, important, wetland
habitats. In-the-field recordings of many birds and amphibians provide an added
dimension to the photographs. 72 frames, cassette and guide. Slides, video or filmstrip.
(Slides order #SS-1090S ....$99.95, filmstrip order #SS-1090F......$49.95.)

CONTENT SAMPLE: 9. Extensive marshes may also occur along sea coasts where
the terrain is flat and there is some protection from high winds and waves. These marshes are
also very productive, since the rising and falling tides periodically replenish mineral nutrients
and food items.

EXPLORING FRESHWATER COMMUNITIES--CD-ROM Order #CDR-1550.........$99.95
Lab Pack of 5 Order #CDR-1551.........$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.

THE SALT MARSH BIOME Order #117.........$42.50

A detailed study of this most fertile of all biomes. Explains important interrela-
tionships of the aquatic food chain with special emphasis on the role of Spartina grasses,
surveys the plant and animal resources of the salt marsh and the importance of these
areas to continuing bountiful life in the sea. Coverage includes tidal cycles, Spartina,
glasswort, and insects. 20 slides and detailed guide.

CONTENT SAMPLE: 20929 If one could draw a line to separate salt marsh areas from
normal dry-land areas, the line would follow the tideline, the edge of the incoming ocean tides and
waves. It would follow the banks of the many tidal streams which flow into the ocean, and would
trace the edges of coastal areas which have no rivers or creeks.

The extent to which a marsh thrusts inland depends on the surrounding terrain, and
therefore changes as that terrain changes. Nature, man, or both acting together, can cause
these changes. Wind and water erosion can bring down tens of thousands of tons of top soil and
raise the level of the marsh land above the reach of the tide. The marsh grasses themselves can
act as a dam against which this buildup can progress.

REVIEWS: "The slides have been carefully chosen...well written.... Highly recommended
for instruction at the secondary level and for independent study at the college level." Previews.

ECOLOGY OF A SWAMP #122 Order #122........$42.50

An introduction to the ecosystem of the Okefenokee Swamp in Georgia. A
photographic exploration of the world of millions of singing creatures--insects, reptiles,
amphibians, birds--and a garden of spectacular flower displays. Text details the
significant and unusual characteristics of the animals and plants presented and provides
insights into their valuable and unique wetland biome. 20 slides and detailed guide.

CONTENT SAMPLE: 20961 Despite fire and logging, there are still 400 year old bald
cypresses in the swamp, some over 36 m (120 ft.) tall. Few trees can match its value for lumber,
for the wood is light, straight-grained, durable, resistant to warping, and practically decay-proof.

Its wide, flaring base gives it a low center of gravity and, with its widespread root system,
helps stabilize it in its shifting, watery substrate. The roots throw up protuberances, commonly
called "knees," but more formally known as pneumatophores, which project above the water
surface. They look like supporting buttresses and are thought to be a means whereby additional
oxygen is supplied to the submerged roots.

REVIEWS: "...a very good program..." J.R.E. Okefenokee National Wildlife Refuge.
