AbstractThe Rochdale Formation of eastern New York (= Fort Ann and lower Bascom formations, designations abandoned) is now recognized to record the earliest stages of the Great Ordovician Radiation of cephalopods. The earliest Bassleroceratidae, Tarphyceratidae and endoceridans on the east Laurentian shallow carbonate platform occur in the upper, thrombolite-bearing member of the Rochdale. This fauna demonstrates that the earliest radiation of Ordovician nautiloids took place in the late Tremadocian and is best recorded in tropical platform facies. Revision of this cephalopod fauna based on approximately 190 specimens collected along a 200 km, N–S belt in easternmost New York has provided new information on inter- and intraspecific variation of earlier described species. The ellesmerocerid Vassaroceras and the endocerids Mcqueenoceras and Paraendoceras are emended. New taxa include Bassleroceras champlainense sp. nov. and B. triangulum sp. nov., Mccluskiceras comstockense gen. et sp. nov., Exoclitendoceras rochdalense gen. et sp. nov. and Paraendoceras depressum sp. nov. A rank abundance plot of 146 specimens from a locality in the Lake Champlain lowlands provides information on the community structure of a nautiloid fauna in which the longiconic cyrtoconic Bassleroceras is shown to dominate strongly. The nautiloid community structure of the Rochdale Formation is similar to that of the underlying Tribes Hill Formation (late early Tremadocian) with respect to the depositional setting, diversity and evenness but displays a remarkably increased taxonomic distinctness.

Specific Timing

International, rather than domestic, causes of both the Bank Holiday of 1933 and the calm in the banking system that followed are emphasized here. New information on gold losses by the New York Federal Reserve, rather than domestic currency hoarding, serve to explain the Bank Holiday's specific timing. Expectations that Roosevelt would devalue the dollar stimulated much of the gold loss. I also argue that Roosevelt's restrictions on gold holdings and foreign exchange dealings and his devaluation of the dollar by 60 percent were more important to the stability of the banking system after the Bank Holiday than was deposit insurance.

This short (179 pages), well-composed text includes a presentation of the anatomy, hemodynamic characteristics, and surgical management of five congenital cardiovascular abnormalities. Although not much in the way of new information is offered, the material is easy to read and is followed by an excellent bibliography. Chapters dealing with patent ductus arteriosus, coarctation, atrial and ventricular septal defects, and tetralogy of Fallot comprise the materials covered by the text. With certain exceptions, for instance, the routine use of chloramphenicol as a postoperative antibiotic, the discussion of the surgical treatment and postoperative management of these anomalies is very well done.

AbstractRecent research indicates that antiretroviral prophylaxis significantly reduces occupationally related human immunodeficiency virus (HIV) seroconversion. This article outlines principles on which guidelines were based for treating aggressively those healthcare workers (HCWs) exposed to HIV occupationally at the Catholic Medical Center in Jamaica, New York. These recommendations attempt to provide HCWs with the best possible available antiretroviral therapy to treat occupational HIV seroconversion. New options must continue to be explored as new information becomes available.

AbstractA remarkable fossil assemblage composed of five gastropod taxa is described from the Early Miocene of Santa Cruz (Patagonia, Argentina) in southernmost South America. The assemblage includes extinct and living genera South America, and on geographic distributions and represent background new information on spatial and across time distributions as well as identification of new taxa. A new taxon,Patagocharopa enigmatican. gen. n. sp., is tentatively assigned to Charopidae.Gastrocopta patagonican. sp. (Vertiginidae) represents the oldest record ofGastrocoptain Argentina and the southernmost record for the Americas.Punctum patagonicumn. sp. (Punctidae) represents the first record ofPunctumfor continental South America, and characterized by a protoconch with traces of axial costulae and a teleoconch with strong radial ribs.Zilchogyra miocenican. sp. is the first Miocene record of the charopid genusZilchogyra. Fragments of a possibleScolodonta(Scolodontidae) are recorded. Overall, the assemblage represents an important and useful paleoenvironmental tool. This fauna suggests that a more temperate and humid environment than today—with a more dense vegetation cover—was prevalent at this site during the Early Miocene.

Several pre-emergent herbicides (azafenidin, oxyfluorfen, and imazaquin–pendimethalin mixture), used for weed control during the establishment of short-rotation willow plantings, were tested for their impact on population density, species richness, and community structure of predaceous (Gamasina) and saprophagous and (or) mycophagous (Oribatida) soil mites. The experimental control was hand-weeded (no herbicide). Two site preparation treatments were used: conventional (disked) and erosion controlled (no-till with cover crop of winter rye). The influence of herbicide application on non-target organisms (soil mites) cannot be generalized, with groups being differentially affected. Overall, Oribatida were most affected by herbicides. Among specific herbicides, azafenidin and oxyfluorfen had a negative effect on density and species richness of soil mites. The response of Oribatida and Gamasina to herbicides was species-specific. Two species of Oribatida ( Sellnickochthonius immaculatus (Forsslund) and Liochthonius lapponicus (Trägårdh)) declined significantly in all herbicide-treated plots. The cover crop residue had positive effect on both Oribatida and Gamasina; the negative effect of herbicides on Oribatida was greatly mitigated by cover crop. Herbicides appear to reduce mite diversity and alter community structure, but they do not always affect abundance. We speculate that the sensitivity of Oribatida to herbicides can reflect the indirect impacts of herbicides on soil microflora.
