AbstractThe ring vessel (or “doughnut jar”) and the stirrup spout-handle concepts probably diffused together, not only from Peru to Mesoamerica during the pre-Classic, but also from Mesoamerica to the southwestern and eastern United States. In the Southwest they first appeared in the San Juan area around A.D. 500; later they were accepted by other Anasazi and Anasazi-influenced cultures and persisted to the historic period. The apparent interest of the early Anasazi in odd vessel shapes may account for the acceptance of these two shape concepts by the Anasazi rather than by the Hohokam or Mogollon. The ring vessels and stirrup tubes may have continued into the historic period because, unlike most of the other odd forms, these had come to be traditional in certain persisting ceremonial contexts. However, before these suggestions can be adequately evaluated, more information from the Southwest is needed, and the meanings and associations of the two forms in Mesoamerica must be analyzed.

AbstractA 5-year study of the black flies of east-central Saskatchewan revealed 21 species, including Simulium incognitum sp.nov. Chromosomal and ecological evidence for reproductive isolation is presented for this new species, formerly known as S. venustum Say CC4, and S. venustum Say CC. All 21 species in the study are associated with productive streams and rivers. As many as nine of these species might comprise the pest assemblage harassing livestock. The major pest, S. luggeri Nicholson and Mickel, is cytologically distinct from populations in the eastern United States on the basis of a two-step, Y-linked inversion in the IIS chromosomal arm. Simulium luggeri is the only livestock pest that breeds almost solely in large streams and rivers. The other eight probable pests breed entirely or partly in streams less than 10 m wide, often below beaver dams, suggesting that management efforts should specifically target these sites.

AbstractJapanese stiltgrass is one of the most aggressive, rapidly spreading invasive plants in the eastern United States. Management guidelines state that mowing can help manage Japanese stiltgrass but that mowing is most effective when done late in the season after the plants begin to flower and before they set seed. In this study, I tested the effectiveness of mowing at three different times between mid-June and early September in 2009 and 2010, as well as mowing twice in 1 yr and for two consecutive years. The effectiveness of mowing Japanese stiltgrass was determined by measuring percentage of cover, biomass, seed production, and the number of stems in the summer following mowing. All mowing treatments significantly reduced percentage of cover, biomass, seed production, and the number of Japanese stiltgrass stems the following year. In 2009, all of the mowing treatments significantly reduced biomass, percentage of cover, and seed production. The latest mow, at the end of August, resulted in a slightly greater reduction of cleistogamous seeds. In 2010, the earliest mowing treatment, in mid-June, did not reduce cover and biomass as much as the other mowing treatments. Overall, these results suggest that mowing can be an effective control method for Japanese stiltgrass and that mowing any time after June should be effectively equivalent, although later mowing may provide some marginal advantage.

Heirloom tomato production is increasing in the Eastern United states as consumer demand increases. Pruning and suckering heirloom tomatoes have not been studied to see if there is any need for this labor-intensive activity. A 2-year study was undertaken to evaluate whether pruning or suckering would affect yield or fruit size for two heirloom cultivars (`Mortgage Lifter' and `Prudens Purple'). The treatments imposed on the cultivars were 1) removing all suckers from the second or third stem down after the flower cluster; 2) removing the bottom two suckers, or 3) removing no suckers. Pruning had no effect on early yield or fruit size (harvests 1–4). Mid-season (harvests 5–7) total and marketable yields were significantly higher for removing two suckers or not suckering over the other two treatments for year 1, but not year 2. The tomato fruit size was only reduced for the non-suckering treatment. There were no statistical differences among the pruning treatments for yield or fruit size for late season harvests (8-10) for both years. Marketable yields were statistically higher for no suckering over the two- and three-stem treatments, but not different from two suckers when all harvests were combined for the season for year 1. No statistical differences were observed in year 2. However, fruit size was reduced when not suckering compared to the other treatments. The cultivar `Prudens Purple' did have higher total and marketable yield than `Mortgage Lifter' for both early and total combined harvests, but not for mid- or late-season harvests in year 1. There were no statistical differences between the two cultivars for year 2.

AbstractPorcelain berry and bushkiller are confamilial, exotic, perennial vines in the Vitaceae family that are considered nuisance/invasive weeds of natural and riparian areas in the eastern United States. To better understand the competitive abilities of these aggressive weeds, greenhouse competition experiments were conducted on cuttings of porcelain berry, bushkiller, and Virginia-creeper, a native member of the Vitaceae family. Plants grown singly or in combination were monitored for stem growth and biomass production. In this research, porcelain berry and Virginia-creeper exhibited similar rates of stem growth, whereas bushkiller grew taller and faster than either of the other species. Porcelain berry stem growth was reduced in competition with bushkiller. All three species exhibited reduced stem biomass when grown with both other species. Root biomass of porcelain berry and Virginia-creeper were not affected by competition, but bushkiller, which produced the heaviest roots, exhibited reduced root biomass when grown with both other species. Porcelain berry root length was reduced by competition with both other species, but neither Virginia-creeper nor bushkiller root lengths were affected by competition. These results indicate that bushkiller is likely the strongest competitor of the three species studied. In these experiments, porcelain berry was less aggressive and vigorous than bushkiller but was similar to Virginia-creeper.

Because the salamander Megalobatrachus davidianus makes sounds like a baby crying, its common name in China is ‘baby fish’. The largest amphibian now in existence, it may grow to 180cm in length and weigh up to several dozen catties (1 catty = ½kg); one specimen caught in Hunan Province weighed 65kg. It is one of three salamander species belonging to the Cryptobranchidae. The other two, Cryptobranchus japonicus in Japan and C. alleganiensis in the eastern United States, are similar to the Chinese species in shape and size, but the American one is much smaller.

AbstractResults are presented for a 4-year (1986–1989) cytological survey of the Simulium venustum/verecundum complex on the Avalon Peninsula, Newfoundland, Canada. Based on 4578 larval identifications from 72 sites, six species in the S. venustum/verecundum complex were found: S. truncatum Lundström (= S. venustum EFG/C), S. venustum CC2, S. venustum CC3, S. venustum AC(gB), S. verecundum Stone and Jamnback (= S. verecundum AA), and S. rostratum Lundström (= S. verecundum ACD). The possibility that S. venustum A/C and S. venustum Say (= S. venustum CC) exist on the Avalon Peninsula in low numbers cannot be excluded, although this is doubtful. Discoveries of EFG/C and CC2 reciprocal sex exceptions support the hypothesis that exceptional individuals are the product of crossover. Cytological results confirm the supposition that S. truncatum, S. venustum CC2, S. venustum CC3, S. venustum AC(gB), S. verecundum AA, and S. rostratum are all distinct species. Results are interpreted within the broader geographic context of the S. venustum/verecundum complex. Three new cytotypes are recognized: one, from Quebec, we place under AC(gB); the other two, from the eastern United States, fall under CC2.

In his recent study of the Fort Ancient aspect, J. B. Griffin has described two unique vessels from the Madisonville site as follows:Two of the most unusual vessels from the site have pedestal bases. One of them was recovered relatively intact from the right side of the skull of an extended adult male. This jar is entirely typical of the Madisonville Cord-marked jars with the exception of the stand, which is an anomaly in any cultural group in the eastern United States. The vessel and the stand are 19 cm. high, and the stand alone is 6.5 cm. This unique piece is in the Cincinnati Art Museum. On the other jar the pedestal has been broken off, but there is no doubt but that such a base was formerly attached. This jar does not have any handles, but in its other traits it is a representative Madisonville Cord-marked jar.

In “The Canadian Entomologist” for August, 1903 (*), I called attention to the sounds produced by Ranatra fusca, Pal. B. Further study has shown me that the bug I then referred to was in reality Ranatra quadridentata, Stal., and that R. fusca is very rare in the north, if, indeed, it occurs at all, the former being the commonest species in the Eastern United States, the latterm on the other hand, being more southern. The nots referreed to, therefore, apply to R. quadridentata, Stal.

The number of English Language Learners (ELL) is increasing in all regions of the United States. Although the majority (71%) speak Spanish as their first language, the other 29% may speak one of as many as 100 or more different languages. In spite of an increasing number of speech-language pathologists (SLPs) who can provide bilingual services, the likelihood of a match between a given student's primary language and an SLP's is rather minimal. The second best option is to work with a trained language interpreter in the student's language. However, very frequently, this interpreter may be bilingual but not trained to do the job.
