Subglacial meltwater channels (NYE channels or N-channels) in sandstone at Hindostan Falls, Martin County, Indiana.
January 1, 2001... ABSTRACT. A flat-topped slab of sandstone bedrock about the size of a football field is exposed at low water just downstream from Hindostan Falls, Martin County, Indiana. The surface of this rock exhibits numerous subparallel linear grooves,...

Quaternary record at Cagles Mill, Putnam County, Indiana.
January 1, 2001... ABSTRACT. Indiana's most time-transcending stratigraphic section of Quaternary deposits is probably the exposure in the wall of the emergency spillway at Cataract Lake in Putnam County, Indiana. The oldest sediments, whose probable age is early...

The New Harmony Group (Lower devonian) revisited.
January 1, 2001... Alan S. Horowitz (1) ABSTRACT. The New Harmony Group is present only in the subsurface of southwestern Indiana, contains in ascending order the Grassy Knob Chert, The Backbone Limestone, and the Clear Creek Chert, and ranges in thickness...

Solvent effects on the electronic transition energies of porhyrins in binary solvent mixtures.
January 1, 2001... ABSTRACT. The UV-Visible absorption spectra of free-base and nickel porphyrins have been investigated in binary mixtures of solvents with similar polarities and dissimilar refractive indices. The Soret band energies of five porphyrins show...

Stathmin expression in the Placenta and Embryonic Brain.
January 1, 2001... ABSTRACT. Stathmin is a member of a family of proteins believed to play important roles in neural development. In the current study, expression of stathmin forms in rat brain was examined from day 15 of gestation through the neonatal period and...

Woody vegetation survey of beall woods nature preserve, Wabash County, Illinois.(Statistical Data Included)
January 1, 2001... ABSTRACT. The Beall Woods Nature Preserve in Wabash County, Illinois contains the best remnant of the immense forest once associated with the Lower Wabash River Valley. The forest was studied in 1997 using 3 ha plots (100 m X 300 m) in each of...

The structure and composition of vegetation in the lake-fill Peatlands of Indiana.(Statistical Data Included)
January 1, 2001... Anthony L. Swinehart (1) ABSTRACT. The vegetation of 16 lake-fill peatlands in northern Indiana was systematically sampled. Peatland types included fens, tall shrub bogs, leatherleaf bogs and forested peatlands. No significant difference...

The lignicolous fungi of Ginn Woods, Delaware County, Indiana.
January 1, 2001... ABSTRACT. Our knowledge of the distribution of macromycetes, both basidiomycetes and ascomycetes, in Indiana is wanting. A survey of the various herbaria within Indiana revealed only nine containing fungal specimens and most having fewer than...

A transmission electron microscopic study of the pharyngeal armature in the larval Drosophila Melanogaster.
January 1, 2001... ABSTRACT. The ultrastructure of pharyngeal armature was investigated in the larval Drosophila melanogaster, which principally feeds on yeasts and bacteria. The pharyngeal epithelial cells have large nuclei with prominent nucleoli. Their...

Checklist of the Crayfish and Freshwater Shrimp (Decapoda) of Indiana.
January 1, 2001... ABSTRACT. Crayfish and freshwater shrimp are members of the order Decapoda. All crayfish in Indiana are members of the family Cambaridae, while the freshwater shrimp belong to Palaemonidae. Two genera of freshwater shrimps, each represented by...

Three-toed Amphiuma (Amphiuma tridactylum) in Southwestern Indiana.
January 1, 2001... ABSTRACT. No specimen of the genus Amphiuma has been recorded in Indiana since 1880, although habitat potentially suitable to species of this genus is present along riparian corridors in southern sections of the state. We recovered a dead...

The gray bat, Myotis grisescens, in Indiana.(Statistical Data Included)
January 1, 2001... ABSTRACT. Hahn (1909) was the first to report the presence of the gray bat, Myotis grisescens, in Indiana; but through 1977, only 22 individuals had been reported. Cope and Richter (1978) provided the first evidence that a maternity colony...

Food of eptesicus fuscus, the big brown bat, in Indiana in the absence of cultivated fields and agricultural pests.(Statistical Data Included)
January 1, 2001... ABSTRACT. Big brown bats (Eptesicus fuscus) in Indiana feed heavily on agricultural pest insects. Big brown bats at Crane Naval Surface Warfare Center, Martin County, Indiana, where agricultural fields were not present, had almost the same diet...

Bats of the Wabash and Ohio River Basins of Southwestern Indiana.(Statistical Data Included)
January 1, 2001... ABSTRACT. The purpose of this project was to sample streams, bayous, and swamps of the Wabash and Ohio River basins of southwestern Indiana for bats, particularly for the five species considered to be rare or endangered in Indiana. These are...
