MANKIND'S RELATIVES--THE PRIMATES Order #419.....$42.50

Details life styles, social activities, evolutionary development, ecological niches,
range, habitat, morphology, behavior and worldwide status of eight primate families.
Includes representatives of the prosimians, New and Old World monkeys, apes and
men: tree shrew, lemur, loris, potto, spider monkey, marmoset, macaque, baboon,
orangutan, chimpanzee, gorilla, and human. 2O slides and detailed guide.

CONTENT SAMPLE: 17524 Unlike the lemurs which are well-known for their long,
heavily-furred tails, the slow loris (Nycticebus coucang) has only a mere vestige of a tail. It
is native to the tropical rain forests of Assam, India; southeast Asia; such Indonesian islands as
Java and Borneo, and Tawitawi in the Philippines.

A nocturnal, almost wholly arboreal species which only rarely descends to the ground,
the slow loris spends most of its time high in the branches of trees, moving about slowly and
deliberately. It does not leap or jump as lemurs do.

During the day, the slow loris sleeps in a tree hollow, in a crevice formed by tree
branches, or merely on a tree limb itself. At night, it seeks food. Its diet consists mainly of
insects, but it also eats small mammals, fruits, leaves, lizards, birds and bird's eggs, and tender
young shoots. It captures animal prey by approaching very slowly and quietly, hand-over-hand,
then attacking suddenly and rapidly. When foraging for fruits and seeds, it often hangs by its
feet, thus freeing both hands to grasp and hold the fruit while it eats, with head hanging
downward.

Little is known of the social behavior of this nocturnal animal. It is most often found alone
or with a mate. Like the lemurs, it too is in extreme danger of extinction.

CHIMPANZEE SOCIETY AND BEHAVIOR Order #437.......$42.50

Social organization and behavior of wild chimpanzees in the Gombe reserve.
Emphasizes growth and development of infants and adolescents, socialization
processes, family structure, learning, social traditions (including tool-using skills), male
and female roles, social rank and status. Comparisons are made with other primates,
including humans. 2O slides and detailed guide.

CONTENT SAMPLE: 20857 An outstanding example of subsistence technology at
Gombe is the technique known as termite fishing. When these insects are in season, the
chimpanzees spend four to eight hours each day sitting at termite mounds, probing into narrow
tunnels with various tools. The technique seems deceptively simple when performed by a skilled
adult, yet human researchers must practice for months to learn the four basic steps of termite
fishing: (1) finding the tunnel entrances on a smooth clay mound; (2) selecting the proper tool,
which must be supple enough to enter the twisting tunnels and strong enough to withstand the
sharp pincers of soldier termites defending the mound; (3) probing into the tunnel with a twisting
motion and vibrating the tool to attract termites; and (4) extracting the termite-laden tool without
brushing off the termites against the tunnel walls. After all this has been accomplished, the
insects must be bitten off the tool, then rapidly chewed and swallowed to avoid painful bites on the
lips and tongue. Termites taste tart and acidic, somewhat akin to a citrus flavor, and quite unlike
any other available foods. Techniques for collecting other kinds of insects differ in many details,
and chimpanzee communities in other areas do not use exactly the same techniques. In fact,
chimpanzee populations in East, Central and West Africa have somewhat different “material
cultures,” perhaps simpler yet similar to the stone tool cultures of early man.

ECOLOGY OF THE GOMBE NATIONAL PARK Order #119........$42.50

Details the complex mosaic habitat, flora and fauna of this famous East African
wildlife reserve established in 1968 to protect seven primate species. Where Jane
Goodall did her chimpanzee research described in "In the Shadow of Man." Includes a
map of the park and photographs of Lake Tanganyika; various vegetation types and
zones; olive baboons; chimpanzees nesting, grooming and collecting termites; fish eagle
and genet. 20 slides and detailed guide.

CONTENT SAMPLE: 20820 Gombe National Park (4°41’S, 29°38’E) is an oblong strip
of rugged, mountainous terrain dominated by many steep-sided ridges and valleys. (See map
at the end.) Most of the 16 major valleys contain swift streams that flow all year, providing
the larger mammals with an assured supply of drinking water, a feature of great importance in dry
months because some of the local fauna do not frequent the lakeshore environment. The area is
covered by a complex mosaic of vegetation types, with rolling grasslands on the ridge crests,
open semi-deciduous woodlands on the steep slopes, and thick evergreen forests along the
valley floors.

The park survives as a natural habitat because it is a small, isolated ecosystem
surrounded by distinct boundaries. Lake Tanganyika, which lies 772 m (2,532 ft.) above mean
sea level, forms the western boundary. The high wall of the rift escarpment, which rises another
750 m (2,460 ft.) and more above the lake, forms the eastern boundary. Ridges stretching from
the high rift to the lakeshore protect the northern and southern boundaries, beyond which are
several fishermen’s villages and some banana plantations. Beyond the rift escarpment lies the
vast, largely uninhabited drainage basin of the Malagarasi River, which seasonally floods several
thousand square kilometers of bush country as it flows across the plateau region, into the lake.
Together with the lake itself, this floodplain serves as a formidable barrier to faunal migration
between the western lowlands and the eastern highlands. So the narrow zone pressed between
the rift escarpment and the lake shore is a unique habitat where major African biomes overlap.
Thus, many of the large mammals indigenous to the eastern highlands--such as lion, elephant,
zebra and wildebeast--are entirely absent in the transitional zone, whereas the primates normally
found in the western lowlands, such as the chimpanzee, are present there. The distributions of
plants, reptiles, birds and small mammals also reflect the special conditions in this zone.

THE BEGINNING Order #811.......$42.50

Delivery of a baby by natural childbirth. Photos include pregnancy, prenatal
care, ultrasound exam, scenes in the labor and delivery rooms, early labor, predelivery
and delivery, the newborn child, initial care of the infant, foot printing, post partum care,
the mother and the child. 20 slides and guide.

CONTENT SAMPLE: 19120 As the months went by, I grew and grew and grew. I
experienced a strange sense of both inner and outer change and suddenly became aware that I
was not as spry and agile as before and could not pass through as small a space as previously.

For the reasons outlined earlier, we chose a delivery method known as psycho-
prophylaxis (prepared childbirth), first taught by the French obstetrician Fernand Lamaze. The
method uses two approaches: education about what to expect during labor and delivery,
including a tour of the hospital’s maternity area; and a variety of breathing exercises to be used
during labor and delivery to distract the mother’s conscious awareness of pain and help her to
relax. Lamaze also discourages the use of drugs and encourages the mother to be awake during
the delivery. Parents attend Lamaze classes together, practice the breathing exercises together
at home, and, in most hospitals, Lamaze-trained fathers are permitted to be present during labor
and delivery to assist the mother. Attending Lamaze classes during the last months of the
pregnancy helped prepare us for all that was to come.

REVIEWS: “Flexible packaging allows use...in the format most suitable for each
class. Recommended as an instructional tool...” Previews.

HUMAN DEVELOPMENT Slides order #SS-0235S.......$42.50

Full color graphics depict the process of ovum development, fertilization, fetal
development, and birth. 20 frames and guide. (Filmstrip order SS-0235F .......$15.00.)

CONTENT SAMPLE: 7. Implanted in the uterus, the embryo begins to develop
extraembryonic membranes. Lower left: One month embryo. The green structure is the “yolk
sac,” which actually contains no yolk. The line encircling the embryo and its surrounding fluids is
the amnion. Surrounding the entire structure is the placenta, an organ made of both embryonic
and maternal tissues. Lower center: Two-month embryo. Here the amnion has increased, the
yolk sac decreased, and the umbilicus has become more distinct. The chorion is the membrane
just inside the placenta. The pink area extending to the placenta contains the allantois which
acts as a waste dump and is incorporated into the umbilicus. Lower right: Three-month embryo.
By this time fetal circulation is being established with the placenta through the umbilicus.

CHILDBIRTH Slides order #SS-0660S.......$42.50

A selection of outstanding close up photographs of normal and Cesarean
deliveries from the obstetrician's view of an actual delivery. Guide provides details on
what mothers-to-be can expect. 2O frames and guide. (Filmstrip #SS-0660F....$15.00.)

CONTENT SAMPLE: 6. Throughout the first stage of labor the uterus contracts and
relaxes in its attempt to expel the fetus. It is this process that is commonly called “labor.” The
frequency, duration and intensity of contractions increase as delivery nears, resulting in a
thinning out of the uterine wall, a process called effacement. During effacement the cervix
expands or dilates from its closed position to an open position, usually 8 to 10 cm in diameter,
thereby allowing passage of the baby from the uterus through the birth canal. Shown on the left
is an uneffaced uterus without dilation of the cervix, and at the right complete effacement and
dilation.

The second stage of labor follows uterine effacement and cervical dilation.
