Anatomical Characters

The anatomy of Urocleidus aculeatus (Van Cleave and Mueller, 1932) Mueller, 1934 from the gills of Stizostedion vitreum (Mitchill) in Ontario, Canada, and New York State, U.S. A., is redescribed. Urocleidus aculeatus is regarded as type species of Urocleidus Mueller, 1934 and a revised generic diagnosis is presented. The taxonomic importance of some anatomical characters and the possible origin of some ancyrocephaline forms are discussed.

AbstractSiricids and their parasitoids were reared from Scots pine (Pinus sylvestris L. (Pinaceae)) trees infested by Sirex noctilio F. in central New York State. Sirex noctilio accounted for 94.3% of the siricid specimens emerging, totaling 1313 specimens from six trees, with a maximum of 495 from one tree. Of the individuals emerging per tree, 20.6 ± 5.2% were female. Two native siricids, Sirex nigricornis F. and S. edwardsii Brullè, also emerged from trees but in low numbers. Three hymenopteran parasitoid species that attack siricids emerged, totaling 21.8 ± 6.4% parasitism per tree. Ibalia leucospoides ensiger Norton (Ibaliidae) was by far the most abundant parasitoid, at 20.5 ± 6.3% parasitism per tree. The percentage of female S. noctilio emerging was positively correlated with wood diameter, whereas percent parasitism by I. l. ensiger was negatively correlated with wood diameter.

Kilmer is a multicomponent Paleoindian site located in the Appalachian Uplands of New York State. It is situated on high and low late Pleistocene outwash terraces (T2 and T1). In mountainous areas, these landforms are susceptible to weathering and erosional processes. The paucity of sites in the Appalachian Uplands is likely the result of geologically active landscapes. The occurrence of Paleoindian sites in the mountainous terrain of eastern North America suggests economic diversification, a cultural response to unpredictable food resources near the end of the Pleistocene.

A New Species

We propose a new species of oribatid mite, Unduloribates dianae sp. nov., based on material collected from a variety of boreal habitats in the Canadian Provinces Newfoundland, Nova Scotia, Québec, Alberta and British Columbia, and in New York State in the USA. This is the first species in this genus from the Nearctic. Description is based on adults and all immature stages. We present an expanded generic diagnosis and a key to world species of Unduloribates, and argue for the retention of Unduloribatidae as a monogeneric family in Phenopelopoidea.

Significant Patterns

The nature of Early Paleoindian economies in late Pleistocene eastern North America has been extensively debated by archaeologists. To better understand paleoeconomies we need to examine intraregional and interregional diversity in the production, consumption, distribution, and exchange of materials that sustained or reproduced early Paleoindian livelihoods. Coarse-grained comparisons drawn on the composition of flaked-stone tool assemblages from early Paleoindian sites in the Northeast (western New York State) and the western Midwest (the confluence area of the Mississippi, Missouri, and Illinois rivers) show varying degrees of homogeneity and heterogeneity in the use of tool stone. Statistically significant patterns from stone procurement and tool manufacturing sites, base camps, and food procurement and processing sites are presented in support of a pancontinental model of flexible economies during a period of rapid and dramatic environmental change.
