Two Populations

Evidence is presented that the western North American plant, Iva axillaris Pursh, consists of two populations which are recognized by the authors as subspecies. Subspecies axillaris, 2n = 36 and 54, is found only east of the Continental Divide and ssp. robustior comb, nov., 2n = 36 and 54, found mainly west of the Divide. A key is presented to show the differences between the two subspecies. Pollen morphology and seed production are discussed.

Two Populations

Evidence is presented that the western Plantago elongata Pursh and P. bigelovii Gray are distinct taxa, each with two populations recognized by the author as subspecies. Plantago elongata ssp. elongata, 2n = 12, is found from Manitoba to British Columbia and southward to Texas and California and ssp. pentasperma Bassett, 2n = 12 and 36, occurs west of the Coast, Cascade Mountains, and Sierra Nevada from British Columbia to California. Plantago bigelovii ssp. bigelovii, 2n = 20, is mainly a plant of the western coastline from British Columbia to California while ssp. californica (Greene) Bassett comb, nov., 2n = 20, is native only to California, Arizona, and Mexico. Plantago heterophylla Nutt., 2n = 12, is widely scattered in the south eastern portion of the United States from Texas to the eastern coastline, while Plantago pusilla Nutt., 2n = 12, occurs mainly in the central eastern states.

Benjamin Henry Latrobe and the nomenclature of two North American fishes

Fish Louse

A curious error affects the names of three North American clupeids—the Alewife, American Shad, and Menhaden. The Alewife was first described by the British-born American architect, Benjamin Henry Latrobe in 1799, just two years after what is generally acknowledged as the earliest description of any ichthyological species published in the United States. Latrobe also described the ‘fish louse’, the common isopod parasite of the Alewife, with the new name, Oniscus praegustator. Expressing an enthusiasm for American independence typical of his generation, Latrobe humorously proposed the name Clupea tyrannus for the Alewife because the fish, like all tyrants, had parasites or hangers-on.

This forum builds on the discussion stimulated during an online salon in which the authors participated on June 25, 2020, entitled “Archaeology in the Time of Black Lives Matter,” and which was cosponsored by the Society of Black Archaeologists (SBA), the North American Theoretical Archaeology Group (TAG), and the Columbia Center for Archaeology. The online salon reflected on the social unrest that gripped the United States in the spring of 2020, gauged the history and conditions leading up to it, and considered its rippling throughout the disciplines of archaeology and heritage preservation. Within the forum, the authors go beyond reporting the generative conversation that took place in June by presenting a road map for an antiracist archaeology in which antiblackness is dismantled.

The University

In 1990 (Fluegeman and Orr) the writers published a short study on known North American cyclocystoids. This enigmatic group is best represented in the United States Devonian by only two specimens, both illustrated in the 1990 report. Previously, the Cortland, New York, specimen initially described by Heaslip (1969) was housed at State University College at Cortland, New York, and the Logansport, Indiana, specimen was housed at Ball State University, Muncie, Indiana. Both institutions recognize the importance of permanently placing these rare specimens in a proper paleontologic repository with other cyclocystoids. Therefore, these two specimens have been transferred to the curated paleontologic collection at the University of Cincinnati Geological Museum where they can be readily studied by future workers in association with a good assemblage of Ordovician specimens of the Cyclocystoidea.

Sports Leagues

Major League Soccer (MLS) is the top-tier professional soccer league serving the United States and Canada. This study examines factors hypothesized to impact consumer demand for professional sports on team revenue in this nascent league. The estimates are consistent with positive returns to performance, novelty effects from newer teams, and varying impacts from roster quality and composition. Other factors hypothesized to be important for MLS teams (e.g., stadium quality and market demographics) are not associated with team revenue. The estimates are similar to findings in other major North American sports leagues, even though MLS operates with a unique single-entity ownership structure that has the potential to disincentivize individual team investments by league owners.

A SYNOPSIS OF THE NORTH AMERICAN SPECIES OF SYNDIPNUS (HYMEN., ICHNEUMONIDAE)

As noted below the two North American species described in Syndipnus by workers appear to belong in other genrra. In Europe the gunus is represented by nearly a score of species and has been reviewed in recent years by two writers (1, 2). North American collections contain very few representatives of the genus; after combining the material in the National Collection with that from the United States National Museum, the latter kindly loaned to me by Mr. R. A. Cushman, only thirty-seven specimens are available for study.
