A wealth of strikingly unusual and beautiful objects of Indian manufacture were excavated from the burials of the Spiro Mound, Leflore (sic.) County, Oklahoma during 1936-37. Engraved Gulf Coast conch shells, shell beads of a dozen types, river pearls, effigy pipes, long delicately chipped flint blades, feather and textile cloths and precisely incised pottery vessels were excavated in quantities. So unusual was this material that, at the time, the archaeological science was unable to answer a host of questions which immediately arose concerning the identity of the tribe who had made the artifacts and who were buried with them. How long ago had they occupied the region? From where had they come, and where did they go? The chronological relationship of the Spiro Mound Culture to the known cultures of the United States was of particular concern to the investigators. How and where did this tribe fit into the picture of America's past?

In 1972, Bernard argued that marriage was good for men and bad for women. Subsequent research noted that wives, on average, reported lower marital satisfaction than husbands. Furthermore, when differences within couples existed on marital satisfaction, the wife was usually the less satisfied spouse; however, most previous studies of the gender/marital satisfaction relationship had not been based on nationally representative samples. A nationally representative sample from the 1988 Survey of Families and Households was used to assess the relationship of gender with marital satisfaction. Within-couple analyses indicated that wives were less satisfied with their marriages than husbands and that, when substantial within-couple differences occurred with respect to marital satisfaction, the wife was usually the less satisfied spouse. Results provide at least small support for feminist assertions about the relatively adverse nature of marriage for women in the United States.

Crown rust (caused by Puccinia coronata) and stem rust (caused by P. graminis) are two common and destructive diseases of turfgrass in the United States. Crown rust has been associated with perennial ryegrass and stem rust with Kentucky bluegrass when identified based solely on fungal morphology. However, recent studies using molecular identification methods have indicated the host–pathogen relationship of rusts on turf to be more complex. Our primary objective was to quickly and accurately identify P. coronata and P. graminis in symptomatic turfgrass leaves over 3 years on turfgrass samples from across the Midwestern United States. Between 2013 and 2015, 413 samples of symptomatic cool-season turfgrass from Wisconsin and surrounding states were screened using real-time polymerase chain reaction. Of these samples, 396 were Kentucky bluegrass and 17% of them contained P. coronata, 69% contained P. graminis, and 13% contained both P. coronata and P. graminis. In addition, both year and location effects were observed on the distribution of Puccinia spp. collected annually from two locations in southern Wisconsin. This research supports previous conclusions that have identified variability among P. graminis and P. coronata host relationships on turfgrass, and further demonstrates that rust fungal populations on Kentucky bluegrass may not be consistent between locations in the same year or over multiple years at the same location. The increasing evidence of variation in the turfgrass rust populations will likely affect future rust management and turfgrass breeding efforts.

The Relationship

Forty-seven isolates of Ceratocystis ulmi collected from Canada, the United States, the United Kingdom, France, the Netherlands, and Iran were classified with respect to their ability to produce cerato-ulmin (CU) and synnemata, their radial growth, mycelial habit, and pathogenicity.Twenty-nine isolates clearly produced CU in a measurable quantity while 18 isolates produced it only in trace quantities. In general, the former produced fluffy mycelium and were active in synnemata formation. They were aggressive in pathogenicity with one exception. The latter group of isolates generally produced waxy, yeastlike mycelium and formed very few synnemata. They were all nonaggressive in pathogenicity. Radial growth was generally higher among the isolates that produced CU in larger quantities than among those producing CU in trace quantities. The relationship between CU production and pathogenicity affords a method for estimating isolate pathogenicity without the need for host inoculation.
