Biology & Earth Science Outline
I. Indiana Dunes
("The Dunes" is often used colloquially in reference to the entire region
of the Indiana Dunes National Lakeshore, Indiana Dunes State Park, and the
surrounding natural areas, preserves, and both recreational and conservation
areas.)
A. Location, Geological History, & Geological & Physical Features
[ From Wikipedia: https://en.wikipedia.org/wiki/Ice_age]
The major glacial stages of the current ice age in North America are the
Illinoian, Sangamonian and Wisconsin stages. The use of the Nebraskan,
Afton, Kansan, and Yarmouthian (Yarmouth) stages to subdivide the ice age
in North America have been discontinued by Quaternary geologists and
geomorphologists. These stages have all been merged into the Pre-Illinoian
Stage in the 1980s.]
B. Biological/Ecological Features of the Dunes
1. Some common and Important Organisms
2. Common environmental conditions (climate,
temperature and moisture regimes, etc.)
3. Major or notable ecosystems from beach to uplands
a. dunes
b. interdunal; dune & swale
c. bog/fen
d. marsh
e. savanna
f. Beach/Maple forest
Marram grass Little Bluestem

Pitcher Plant
Cottonwood Lupine American Beech
Jack Pine Karner Blue butterfly Black Oak
Juniper Sand reed grass Sugar Maple
C. Ecological Succession
1. essential terminology used to describe the concepts
2. Recognized "steps" or gradients in the change of a community of organisms
over time
a. pioneer
b. early successional
c. mid-successional
d. late successional
e. “climax” and “climax communities”
Here, we recognize that the modern ecological community has adapted the original meanings of the
concepts and terms originally coined by and promulgated by Cowles, Clements, and other early
ecologists. Even early in the development of the community and climax community concepts, Henry A.
Gleason thought the idea of a climax community with a specific association of organisms (specifically
plants) to be too simplistic and suggested that such succession to a stable community was individualistic
to species and might be more random than indicated in the use of a “climax community” description. We
do not ignore Gleason—and those that accepted his critique later in the 20th century— but merely
acknowledge the work of the earliest ecologists and accept some of the more fundamental (and perhaps
simplistic) approaches to identifying the process and progress of ecological succession.
3. role of “disturbance” in ecological succession
4. community stability and biodiversity
II. Caves of Indiana: Limestone, Karst Geology, and Caves
A. Limestone: Geology and basic chemistry of limestone deposits and limestone--with special
reference to Indiana limestone.
1. formed from ancient coral reefs when Indiana was inundated with a warm, generally shallow,
marine environment. During tectonic plate movement or the continent, Indiana was then located on an arc
between where the Bahamas and the SE Caribbean are today and the long axis of the state would have
been largely oriented Northeast or East-Northeast to the pole as compared to our North to South
orientation today.
a. corals require warm shallow seas with only gentle motion to sustain growth over a long period of
time.
b. Ancient coral reefs, including some that go back over 400 million years, have been found in
Indiana near Delphi, Bedford (known for high quality limestone for construction) in the region surrounding
Lake Monroe (Bloomington), and near Jeffersonville along the Ohio River (see: Falls of the Ohio State
Park).
c. Fossils from these ancient reefs and shallow seabeds are highly sought and are found in
museums and private collections all over the world. A handful of groups of organisms are (relatively)
common, are particularly wide spread and have often been used as indicators of geologic time periods:
i. crinoids
ii. corals (main reef [& limestone] builders)
a. solitary horn corals
b. colonial corals
iii. bryozoans
iii. brachiopods
iv. other groups may be less prevalent or located in isolated areas; such as nautiloids,
trilobites, and so on
B. Karst Geology & Topography
1. locations and general geologic features of Karst
topography
Karst features are found in a several
places throughout the world. In Indiana, they are found
in the Southern 1/2 of the state.
a. Mitchell Plain
b. Muscatatuk Plain
2. Karst features are found where there is extensive
underlayment of limestone that developed from shallow
inland seas that supported massive coral reefs.
3. Lost River system - location, main features
C. Caves of Indiana
1. Caves in Indiana are found predominantly in Limestone areas
a. Karst geology common
b. secondarily in dolostone
2. Cave formation — fundamentals of how caves form in limestone
3. Formations and features within Indiana caves (explore terminology)
a. stalagmites & stalactites
b. curtains
c. soda straws
d. crystalline features
e. essential cave & speleological terminology
4. Cave biota and their adaptations
a. classification by where in the cave systems they live (see cave terms sites)
b. Blind cavefish
i. Hoosier Blind Cavefish
ii. Northern Blind Cavefish
c. Cave Crayfish
d. Salamanders
5. Notable or famous Indiana caves
a. Marengo
b. Wyandotte
c. Squire Boone
d. Caves of McCormick’s Creek State Park
III. Notable scientists related to the Dunes, Caves, and Flora
& Fauna of Indiana and their major contributions
A. David Starr Jordan - Ichthyology, Taxonomy & Natural
History of Indiana biota
B. Carl H. Eigenmann - Cave Biota
C. Henry C. Cowles - Ecology of The Dunes, Ecology. While Cowles lived in Illinois and did his studies out of the University of Chicago
(just a short distance across the southern tip of Lake Michigan), his work in the
ecological systems within the Dunes was instrumental in this area acquiring the
acclaim that is has enjoyed and also is a major milestone in the timeline of
knowledge about ecology, in general, and specifically in the concept of
ecological succession and biodiversity.

For steel making there are many generic sites on the internet
available for review or study. Suggest assigning various
students the job of reviewing them for the group.
For thermoset vs thermoplastic polymers an internet search
can provide difference in terms.
