Disjunct Eastern Hemlock Populations Of The Central Hardwood Forests: Ancient Relicts Or Recent Long Distance Dispersal Events?, F. Collin Hobbs, Keith Clay Feb 2013

Disjunct Eastern Hemlock Populations Of The Central Hardwood Forests: Ancient Relicts Or Recent Long Distance Dispersal Events?, F. Collin Hobbs, Keith Clay

Mammoth Cave Research Symposia

Eastern hemlock (Tsuga canadensis) is an evergreen conifer with a contiguous distribution extending from the southern Appalachian Mountains north to Nova Scotia and west across the Great Lakes region. Eastern hemlock is threatened with extirpation from much of this range by an introduced pest, the hemlock woolly adelgid (Orwig et al. 2002). In addition to the contiguous distribution, many small, isolated populations are located within the central hardwood forest region of Kentucky, Indiana, and Ohio (Braun 1928, Potzger and Friesner 1937, Van Stockum 1979). These disjunct populations form clearly delineated, often monospecific stands associated with unique natural features such as …


Breeding Bird Survey Summary From Mammoth Cave National Park, 1995 - 2012, Steve Kistler Feb 2013

Breeding Bird Survey Summary From Mammoth Cave National Park, 1995 - 2012, Steve Kistler

Mammoth Cave Research Symposia

Breeding bird surveys are used by ornithologists to study the variations in bird populations across the United States and Canada. Initiated in 1966, the surveys were originally created by Chandler Robbins and colleagues to study the effects of pesticide use on bird populations.

Today, these data are used to monitor changes in avian populations due to habitat loss, habitat fragmentation, land-use changes, and chemical contamination. The administration of these surveys is jointly run by the US Geological Survey and the Canadian Wildlife Service. Almost fifty years of continuous surveying also provides excellent baseline data which can be used to determine …


Landscape Genetics Of The Marbled Salamander, Ambystoma Opacum, In A Nationally Protected Park, Kevin Tewell, Jarrett Johnson Feb 2013

Landscape Genetics Of The Marbled Salamander, Ambystoma Opacum, In A Nationally Protected Park, Kevin Tewell, Jarrett Johnson

Mammoth Cave Research Symposia

Landscape features may influence the patterns of migration and dispersal of amphibian species and create genetic structure. A primary goal of landscape genetics is to analyze these influences in order to make more informed management decisions. We sampled larvae from 50 breeding ponds within the boundaries of Mammoth Cave National Park and genotyped 12 individuals per pond at 10 microsatellite loci to estimate gene fl ow between ponds. We used GIS layers of habitat types to conduct a least-cost path analysis and determine the relative cost of movement through each habitat type. We were interested in answering two questions: does …


Evaluating Interactions Between River Otters And Muskrats At Bridge Crossings In Kentucky, Ryan Williamson, Joseph Clark Feb 2013

Evaluating Interactions Between River Otters And Muskrats At Bridge Crossings In Kentucky, Ryan Williamson, Joseph Clark

Mammoth Cave Research Symposia

Muskrats (Ondatra zibethicus) prey on freshwater mussels in the Green River within Mammoth Cave National Park (MACA), many species of which are threatened or endangered. Reportedly, muskrat populations have been reduced in some streams where North American river otters (Lontra canadensis) were reintroduced and it has been suggested that river otter reintroduction at MACA might help conserve endangered mussels. To test that idea, we used occupancy estimation methods to evaluate the ecological relationship between muskrats and otters by collecting presence/absence data based on field sign found at bridge crossings in eastern and central Kentucky. Mean detection (p) and occupancy probabilities …


Mammoth Cave In Poetry: Davis Mccombs’ Ultima Thule, Judith Hatchett Feb 2013

Mammoth Cave In Poetry: Davis Mccombs’ Ultima Thule, Judith Hatchett

Mammoth Cave Research Symposia

Davis McCombs, former Mammoth Cave park ranger, received the Yale Younger Poets Award for Ultima Thule, his collection of poems based on his experiences in and with Mammoth Cave, not only of his actual experiences as ranger and cave explorer, but also of the history of the cave, including poems in the voice of Stephen Bishop, cave explorer, cave guide, and also a slave. The detail of McCombs’ examination produces what poet W.S. Merwin called “a grave, attentive holding of a light.” In a sense, his poetry illuminates the cave the way ancient torches and modern lighting have done. This …

This presentation focuses on the results of archaeological investigations conducted within Mammoth Cave and is confined to discussion of the prehistoric materials. These materials were confined to the upper and lower passages of the Historic Tour, the Lantern Tour, and Gothic Avenue trails


The History And Conservation Of Saltpeter Works In Mammoth Cave, Kentucky, George M. Crothers, Christina A. Pappas, Christian D. Mittendorf Feb 2013

The History And Conservation Of Saltpeter Works In Mammoth Cave, Kentucky, George M. Crothers, Christina A. Pappas, Christian D. Mittendorf

Mammoth Cave Research Symposia

Remains of the saltpeter mining operation in Mammoth Cave are a significant feature of several cave tours and figure prominently in the history of cave use. We undertook a comprehensive review of existing historical descriptions and recent archaeological investigations to construct the most reasonable account of how the saltpeter operation worked and assess its current conditions. At least three types of saltpeter vats were constructed in the cave reflecting an increase in the size of the operation and efficiency of processing sediments over time. Remains of three pump towers are also found in the cave in various states of preservation. …


The Mammoth Cave Mushroom Company: A Brief History Of A Short-Lived Venture, Katie Algeo Feb 2013

The Mammoth Cave Mushroom Company: A Brief History Of A Short-Lived Venture, Katie Algeo

Mammoth Cave Research Symposia

The Mammoth Cave Mushroom Company was formed in August 1881 during a particularly contentious period of family struggle for control of the cave, its resources, and tourism operations. This paper documents the history of the company from original company records and family letters. It places the Mammoth Cave operation within the larger historical context of mushroom production in caves as possibly the first such operation in the United States. It traces developments at the cave during the fall of 1881 as Anthony Muzarelli oversaw preparation of mushroom beds and supporting infrastructure and identifies sources of tension between the new mushroom …

A History Of Place: Using Phytolith Analysis To Discern Holocene Vegetation Change On Sanak Island, Western Gulf Of Alaska, Cricket C. Wilbur Jan 2013

A History Of Place: Using Phytolith Analysis To Discern Holocene Vegetation Change On Sanak Island, Western Gulf Of Alaska, Cricket C. Wilbur

Antioch University Dissertations & Theses

This study investigated a terrestrial climate proxy, phytoliths, as a complimentary approach to documenting the dynamics of present and past vegetation on Sanak Island, the largest island in a small island group in the eastern Aleutian archipelago, and as a new basis by which to interpret Holocene environmental variability in Alaska. A phytolith reference collection was established from 59 selected plant species of maritime tundra belonging to 27 families. The grass species and a sedge species produced abundant phytolith forms whereas the majority of dicotyledons in this study were trace producers of phytoliths. A paleoenvironmental reconstruction from fossil phytoliths recovered …


Development And Application Of Methods Used To Source Prehistoric Southwestern Maize: A Review, Larry Benson Jan 2012

Development And Application Of Methods Used To Source Prehistoric Southwestern Maize: A Review, Larry Benson

United States Geological Survey: Staff Publications

Archaeological cobs free of mineral contaminants should be used to source the soils in which they were grown. Mineral contaminants often contain much higher concentrations of metals than vegetal materials and can alter a cob’s apparent metal and heavy-isotope content. Cleaning a cob via immersion in an acid solution for more than a few minutes will result in the incongruent and sometimes complete leaching of metals, including strontium (Sr), from the cob. When using 87Sr/86Sr to determine the location of potential agriculture fields, it is best to either integrate several depth-integrated soil samples or to integrate several …

Farmers' Markets In Kentucky: A Geospatial, Statistical, And Cultural Analysis, Elizabeth Ann Schmitz Dec 2010

Farmers' Markets In Kentucky: A Geospatial, Statistical, And Cultural Analysis, Elizabeth Ann Schmitz

Masters Theses & Specialist Projects

To assess what factors are driving the exponential growth of farmers’ markets in Kentucky, geospatial and statistical analysis of a database of 121 farmers’ markets was conducted. A statewide survey of market leaders and a case study of a single farmers’ market both identified reasons for growing support of farmers’ markets in Kentucky.

Market distribution, vendor levels, and gross sales were mapped against a backdrop of county urban classification, median household income, and education levels. Kruskal-Wallace analysis was used to identify if Kentucky’s rural, micropolitan, and metropolitan markets differ significantly in terms of their age, number of vendors, and market …

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith Oct 2008

Kamper Re-Visited Concert (Program), Klaus Kamper, Janet Bass Smith

Mammoth Cave Research Symposia

One hundred years ago, a young German engineer named Max Kämper, came as a visitor to Mammoth Cave. He became so enchanted with the cavern he obtained permission to map the vast system. For the next eight months Max, along with assistance from cave guide Ed Bishop, meticulously put together a highly detailed and accurate map revealing more of the cave than ever before. He probably never realized his work would be admired by generations to follow. Some admire its artistic expression of the cave. Others see beauty in its precision. Ultimately, it has become the iconic map for generations …


Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons Oct 2008

Slave Guide Legacy At Mammoth Cave, Joy Medley Lyons

Mammoth Cave Research Symposia

Serving as guides and explorers at Mammoth Cave partially rescued four men from the obscurity of enslavement. Stephen Bishop, Materson Bransford, Nicholas Bransford and a young man named Alfred all had their very existence documented in the written journals and diaries of various nineteenth century Mammoth Cave visitors. They were physically described, their personalities contemplated, their intelligence gauged, their dialects imitated. At least one abolitionist characterized Stephen Bishop as a charismatic natural leader who could govern the citizenry of freed men in Liberia, should he choose to relocate there.


Max Kämper’S Introduction To The New World, Stanley D. Sides, M.D. Oct 2008

Max Kämper’S Introduction To The New World, Stanley D. Sides, M.D.

Mammoth Cave Research Symposia

Twenty-seven year old engineer Max Eduard Kämper arrived in America at 4:00 pm on May 16, 1907 and was greeted by a thunderstorm. His presumed goals were to study American manufacturing methods, learn English, and enrich himself musically. New York had so many German immigrants at the time that German was the second most common language spoken in the city. He stayed at the Belvedere House at the corner of 4th Avenue and 18th Street, and the next day visited acquaintances in Newark. He visited New York landmarks and May 20 visited the famed Hippodrome theater. He moved on May …

Searching For Max: The Engineer, The War And The World´S Longest Cave (Part 1), Bernd Kliebhan

Mammoth Cave Research Symposia

In 1908 the German engineer Max Kämper mapped 35 miles of Mammoth Cave, KY. The “Kämper Map,” forgotten in the archives for half a century, is nowadays considered as a masterpiece of underground cartography. Little was known about Max Kämper despite several attempts of American speleo-historians. Most traces were wiped out in two world wars. Nevertheless the authors could find out details of the biography of Max Kämper in German archives. The text is based based upon the radio story “Suche nach Max,” broadcasted by Hessischer Rundfunk - hr1 December 26, 1999, audio download available on http://www.kliebhan.de/kaemper.htm

The Lamps That Lit Their Way, Rick Olson Oct 2008

The Lamps That Lit Their Way, Rick Olson

Mammoth Cave Research Symposia

The distinctive lanterns used at Mammoth Cave from the middle 1800s until 1938 appear to be a locally derived design. Early whale oil railroad lanterns share some characteristics of the Mammoth Cave lanterns, but L&N Railroad lanterns do not appear to have influenced the design. At this time, the design pathway appears to lead from simple open-flame tin candle lanterns to the same lantern with a petticoat lamp affixed in place of the candle, and then finally to the font or oil container being soldered onto the lamp base as one unit. This basic Mammoth Cave lantern varied somewhat over …

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker Oct 2008

Mapping Of Mammoth Cave: How Cartography Fueled Discoveries, With Emphasis On Max Kaemper’S 1908 Map, Roger W. Brucker

Mammoth Cave Research Symposia

Maps came first at Mammoth Cave, Kentucky. Then came explorers who used the maps to make discoveries as they gained a more comprehensive understanding of the longest cave in the world. The saga of mapping at Mammoth Cave parallels the mapping of North America from the 1600s onward. The first map was an “Eye-Draught Map of Mammoth Cave”, penned from memory in 1811, not a survey, to acquaint merchants with the location of saltpeter dirt. In 1835 the managers of Mammoth Cave hired a surveyor, Edmond Lee, to survey and map and profile the main cave passages. Stephen Bishop, a …
