Engineer Cantonment, Missouri Territory, 1819-1820: America's First Biodiversity Ineventory, Hugh H. Genoways, Brett C. Ratcliffe
Great Plains Research: A Journal of Natural and Social Sciences
It is our thesis that members of the Stephen Long Expedition of 1819-20 completed the first biodiversity inventory undertaken in the United States at their winter quarters, Engineer Cantonment, Missouri Territory, in the modern state of Nebraska. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory allow us to evaluate the environmental, faunal, and floral changes along the Missouri River in the intervening nearly 190 years. The historical records form a visual image of a dynamic riverine system in which a highly …
2008 Wildflower Of The Year: Virginia Spiderwort, Tradescantia Virginiana, W. John Hayden
2008 Wildflower Of The Year: Virginia Spiderwort, Tradescantia Virginiana, W. John Hayden
Biology Faculty Publications
Spiderwort is an herbaceous perennial that arises from a cluster of rather stout overwintering roots. Stems may be solitary or more commonly clumped, and usually grow unbranched, reaching heights up to 40 cm tall. Stems are smooth or bear scattered short hairs. Leaves are 2—5 per stem, attached by means of a leaf sheath that is 13 cm long. Leaf blades are dull green, elongate, ending in a gradually tapered tip, flat or keeled, smooth (without hairs), and 1—3.5 dm long by 0.5—2.5 cm wide. Flowers occur in tight clusters located at the stem apex; bracts similar to the leaves …
2007 Wildflower Of The Year: Atamasco Lily, Zephyranthes Atamasca, W. John Hayden
2007 Wildflower Of The Year: Atamasco Lily, Zephyranthes Atamasca, W. John Hayden
Biology Faculty Publications
Atamasco lily is a perennial herb that grows from a subterranean bulb. The bulb is dark, with a short neck and papery tunic formed by remnants of old leaf bases. Leaves are glossy green, linear, flat to somewhat concave, up to one half inch wide, approximately one foot in length and, overall, rather grasslike. When not in flower the plants can be easily overlooked. Flowering stems are leafless scapes that are about as long as the leaves. In crosssection the scapes are hollow. Each scape terminates in a single flower. A few papery bracts subtend the flower stalk where it …
The Vascular Flora And Community Structure Of Little Calumet Headwaters Nature Preserve, Laporte Country, Indiana, Julia L. Angstmann, Paul E. Rothrock, Thomas W. Post
The Vascular Flora And Community Structure Of Little Calumet Headwaters Nature Preserve, Laporte Country, Indiana, Julia L. Angstmann, Paul E. Rothrock, Thomas W. Post
Scholarship and Professional Work - LAS
Little Calumet Headwaters Nature Preserve is a 108-acre tract of woodland and wetland areas that comprise the headwaters of the Little Calumet River in northwestern Indiana. The preserve, consisting of upland hardwood forests, groundwater seeps, and wetland complex, is an area of high diversity due to its topographical variation. A floristic inventory, plot sampling, and seed bank analysis were used to determine the structure and composition of the plant communities. The flora consists of 298 species (27 exotic) representing 188 genera and 84 families. Dominant vegetation of the forest includes Liriodendron tulipifera, Prunus serotina, Packera aurea and Podophyllum peltatum. …
2006 Wildflower Of The Year: Spicebush, Lindera Benzoin, W. John Hayden
2006 Wildflower Of The Year: Spicebush, Lindera Benzoin, W. John Hayden
Biology Faculty Publications
Spicebush is a multistemmed deciduous shrub that grows to a height of one to three meters. Young stems are delicate and may be smooth or finely hairy. Leaves are alternate and simple, with an elliptic to obovate blade that tapers at both the base and apex and is bounded by a smooth margin. Examined closely, the margin will reveal a series of fine hairs that project directly out from the leaf edge. In size, leaves are neither remarkably large nor small; they range from one to six inches in length and up to about two and a half inches wide, …
Flora Of The Gurvan Saykhan Mountains, Tseden Jamsran, Batlai Oyuntsetseg, Radnaakhand Tungalag
Flora Of The Gurvan Saykhan Mountains, Tseden Jamsran, Batlai Oyuntsetseg, Radnaakhand Tungalag
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
Although two major books have been published on the Mongolian flora regional data are often still lacking due to the vast expanses of the country. Therefore we used published information and data from our own fieldwork to compile a relatively comprehensive inventory of the flora of the Gobi Gurvan Saykhan mountains in southern Mongolia.

Vascular Flora Of Van Horn Woods, Plainfield Township, Will County, Il, Joseph Traina
Faculty Publications & Research
The vascular flora at Van Horn Woods Park was surveyed during the 1998-2000 growing seasons. This park is a 30 hectare site located in Plainfield Township, Will County, Illi- nois (SE1/4 S27 T36N R9E). A total of 246 taxa, representing 160 genera and 67 fami- lies, were identified within or immediately adjacent to the park. Seventy-one percent of these taxa were native. Four taxa were collected and submitted to the Morton Arboretum as new county records for Will County. The quality of this site as a natural area was also assessed using quantitative methods based on floral composition and diversity. …

Comparative Genetics Of Seven Plants Endemic To Florida’S Lake Wales Ridge, Eric S. Menges, Rebecca W. Dolan, Rebecca Yahr, Doria R. Gordan
Scholarship and Professional Work - LAS
Here we submit that mathematical tools used in population viability analysis can be used in conjunction with floristic and faunistic surveys to predict changes in biogeographic range. We illustrate our point by summarizing the results of a demographic study of Lobelia boykinii. In this study we used deterministic and stochastic matrix models to estimate the growth rate and to predict the time to extinction for three populations growing in the Carolina bays. The stochastic model better discriminated among the fates of the three populations. It predicted extinction for two populations in the next 25 years but no extinction of the …
