Acceptance of the Clark P. Read Mentor Award: The Teague Self Lessons

The transcript of John J. Janovy Jr.'s speech upon acceptance of the American Society of Parasitologists' Clark P. Read Mentor Award, 2003.

Book Review of Venereal Disease and the Lewis and Clark Expedition by Thomas P. Lowry

Although Lewis and Clark literature has proliferated in the last decade, few works have added scholarly discourse to this field of study. The highly focused Venereal Disease and the Lewis and Clark Expedition, however, will likely stand out on the Lewis and Clark bookshelf as an important contribution.

Book Review of Archaeology as a Process: Processualism and Its Progeny by Michael J. O'Brien, R. Lee Lyman, and Michael Brian Schiffer

The field of archaeology incorporates a confusing assortment of ideas and approaches to the record. With studies ranging widely in ideology and goals, from strict descriptive materialism to sociological interpretation, language used to communicate key concepts (not to mention which concepts are key) also varies widely, resulting in low levels of mutual interest and intelligibility across the discipline. Archaeologists commonly ignore the majority of available literature as a result, further widening intellectual chasms.

BOOK REVIEW of Oceans of Kansas: A Natural History of the Western Interior Sea by Michael J. Everhart

Just as there are seashells on Mt. Everest, there is an exceptional wealth of fossil remains of marine organisms preserved in the chalk of western Kansas. This Cretaceous-aged rock, and the fossils therein, were deposited at a time when a great sea cut northward across the interior of the continent around 85 million years ago, inspiring the provocative title of Everhart's book. The title is true to its subject: documentation of the Cretaceous fossils of western Kansas, their geographic and stratigraphic occurrences, and the inferences that paleontologists can make about how the organisms represented by these fossils may have once lived and interacted with one another.

Hydrogeology, Chemical Characteristics, and Transport Processes in the Zone of Contribution of a Public-Supply Well in York, Nebraska

In 2001, the U.S. Geological Survey, as part of the National Water Quality Assessment (NAWQA) Program, initiated a topical study of Transport of Anthropogenic and Natural Contaminants (TANC) to PSW (public-supply wells). Local-scale and regional-scale TANC study areas were delineated within selected NAWQA study units for intensive study of processes effecting transport of contaminants to PSWs. This report describes results from a local-scale TANC study area at York, Nebraska, within the High Plains aquifer, including the hydrogeology and geochemistry of a 108-square-kilometer study area that contains the zone of contribution to a PSW selected for study (study PSW), and describes factors controlling the transport of selected anthropogenic and natural contaminants to PSWs.

Linkage & Selective Mapping and QTL Analysis in a Harosoy x Clark population of 300 RILs

Four of the 12 major Glycine max ancestors of all modern elite U.S.A. soybean cultivars were the grandparents of Harosoy and Clark, so a Harosoy x Clark population would include some of that genetic diversity. A mating of eight Harosoy and eight Clark plants generated eight F1 plants. The eight F1:2 families were advanced via a plant-to-row selfing method to produce 300 F6-derived RILs that were genotyped with 266 SSR, 481 SNP, and 4 classical markers. SNPs were genotyped with the Illumina 1536-SNP assay. Three linkage maps, SSR, SNP, and SSR-SNP, were constructed with a genotyping error of < 1 %. Each map was compared with the published soybean consensus map. The best subset of 94 RILs for a high-resolution framework (joint) map was selected based on the expected bin length statistic computed with MapPop. The QTLs of seven traits measured in a 2-year replicated performance trial of the 300 RILs were identified using composite interval mapping (CIM) and multiple-interval mapping (MIM). QTL x Year effects in multiple trait analysis were compared with results of multiple-interval mapping. QTL x QTL effects were identified in MIM.
