Taphonomic Analysis

ABSTRACT Among fossiliferous marine facies, deposits rich in stalked echinoderms, particularly encrinites, have long been suspected to be susceptible to taphonomic biases because intact calyxes are under-represented or masked by disarticulated skeletal debris. In the middle Mississippian Fort Payne Formation of south-central Kentucky, penecontemporaneous crinoid-rich facies are exposed in close proximity along the shores of Lake Cumberland. Crinoidal packstone buildups preserve a broad preservational spectrum, with articulated crinoid calyxes with arms and columns attached, intact calyxes, holdfasts, and long articulated columns, in a matrix of entirely disarticulated crinoidal fragments. Along a 250 m transect across the flanks and crest of this buildup, identification of 563 specimens of crinoids and blastoids revealed a symmetrical distribution of taxa in which the crest was dominated by disparid and camerate crinoids and the flanks were dominated by camerates. Taphonomic analysis of the same transect showed that intact crinoid calyxes with or without attached arms and column occurred across the entire buildup, but nearly complete specimens with attached arms and column were most common on the western flank and less common on the crest and eastern flank. Taxonomic and taphonomic distributions demonstrate a primary ecologic zonation across the buildup with only localized post-mortem dispersal of crinoids. This is the first demonstration of primary ecologic zonation of a crinoid community preserved within a single lithofacies. Depending on depositional and taphonomic circumstances, crinoids are preserved intact close to their living site; understanding these physical and biological processes provides a significant feedback in reconstructing these ancient depositional environments.

El presente trabajo constituye una aproximación preliminar al estudio de la actividad de las corridas de ganado en el Departamento de Molinos en los Valles Calchaquíes septentrionales, Salta, Argentina. Se toma como caso el evento de la “separada” de animales, que es la culminación del gran evento de la “corrida”, el cual consta de un desarrollo secuenciado y pautado, de alcance temporal y espacial en la región. Se intenta realizar un aporte al estudio de las estrategias de manejo del ambiente en los Valles Calchaquíes salteños septentrionales, a través del caso de las corridas de ganado en Molinos. Al mismo tiempo buscamos testear la aplicabilidad y eficacia de la metodología de la etnografía visual para el estudio de las relaciones hombre – medio, y sus implicancias en la percepción, manejo y movilidad de estas comunidades en su entorno natural y social.Palabras-clave: Manejo de ganado. Relaciones hombre-medio. Etnografía visual. Andes centrales surCattle Management in Molinos: a proposal for Visual Ethnography on the transhumance of cattle in Northern Calchaquí Valleys, Salta, ArgentinaAbstractThis work is a preliminary study of the activity of cattle management in Molinos in the northern Calchaquí Valley, Salta, Argentina. We take as a case of study the event of "separada" of animals, which is the culmination of the great event of the "corrida", which consists of a sequenced development with wide temporal and spatial range in the region. Our proposal tries to make a contribution to the study of environmental management strategies in northern Salta Calchaquí Valleys, through the case of cattle management in Molinos. At the same time we seek to test the applicability of visual ethnography as a strategy to study the perceptions, management and mobility of these communities in their natural and social environment.Key words: Cattle management. Relationships between humans and their environment. Visual ethnography. South central Andes.

Orobanche Minor

A new set of soybean accessions from south-central China were added to the USDA germplasm collection in 1996. Previous studies have shown that accessions with high levels of resistance to brown stem rot (BSR) can be found in germplasm collected from central and southern China. The objective of this study was to screen these accessions and identify those with resistance to BSR. In a preliminary study, 85 of 623 accessions tested were identified as resistant to BSR. In the second study, these 85 accessions were challenged with multiple biotypes of Phialophora gregata f. sp. sojae to identify those accessions with the strongest resistance. From these two studies, ten accessions were identified that had BSR resistance equal to or greater than the current resistant sources. Accepted for publication 10 June 2003. Published 1 July 2003.

Stratigraphic distribution of two key brachiopod species in the Ramp Creek Formation and Harrodsburg Limestone (middle Mississippian) in south-central Indiana suggests the boundary between the Osagean and Meramecian Series lies in the lower part of the Ramp Creek Formation.Marginirugus magnus(Meek and Worthen), an Osagean index fossil, ranges into the lower part of the Ramp Creek Formation.Warsawia lateralis(Hall), a Meramecian index fossil, also occurs in the lower part of the Ramp Creek Formation and in the lower part of the Harrodsburg Limestone. Thus, the upper part of the Edwardsville Formation and lower part of the Ramp Creek Formation in Indiana are temporally equivalent to the lower half of the Warsaw Formation in the Mississippi Valley. The upper part of the Ramp Creek Formation and the lower part of the Harrodsburg Limestone are temporally equivalent to the upper half of the Warsaw Formation.

Distinguishing Features

This article presents the results of further work on the Dōsiri dialect of Arabic, a preliminary study of which appeared in this Bulletin some time ago.Since this first article appeared, I have been able to examine more closely the extent of 'Ajmi influence on the phonology of the dialect spoken by my Dōsiri informants, and to place their dialect more accurately within the group to which it belongs. It now seems certain that, although this Dōsiri dialect does not share all the distinguishing features of the Nejdi group, the parent dialect does belong to the south-central type of Nejdi dialect. As a result of the placing of the dialect of the Duwāsir a little more exactly, and of the comparative studies this has involved, a more precise formulation of some important phonological and syntactical features can now be made.
