Abstract This paper presents a detailed description of the architectural elements associated with a Late Dorset semi-subterranean structure at the Bell site (NiNg-2), located on the Ekalluk River, southeastern Victoria Island, Nunavut. The 2002 excavation of the house centred on the recovery of detailed information relating to the architectural tradition of the Late Dorset in this area. The structural remains associated with House 6 suggest it was intended for only a short period of occupation that corresponded with the late fall caribou migration through the area. Probably abandoned during the early winter, House 6 is best interpreted as a "between seasons" structure, comparable to the Thule and historic Inuit qarmat.

Conventional Models

Conventional chilling models developed primarily for deciduous fruit crops such as apple and peach are based on the accumulation of optimal chilling temperatures between ≈4 and 7 °C. Cranberry (Vaccinium macrocarpon) is a perennial evergreen woody vine that requires chilling temperatures to overcome its dormancy. Periodic collections of budded stems (uprights) from cranberry beds (cv. Stevens) in central Wisconsin throughout the fall and early winter were forced to determine when dormancy requirements were met in the field. For this purpose excised uprights were placed in deionized water in test tubes at 24 °C and 16-h day (cool-white fluorescent). In both 1996 and 1997 it was observed that uprights were able to break bud and grow in late fall and early winter only after experiencing (in addition to chilling) a prolonged period of temperatures slightly below freezing. As an evergreen plant, cranberry may be receiving critical environmental cues at its leaves. Additionally, the existence of the native cranberry plant in harsh winter environments may have resulted in the need for freezing temperatures during dormancy to ensure survival.

Proximate Analyses

Proximate analyses were made at bi-monthly intervals during 1933–34 on samples of Ostrea lurida, O. virginica, and O. gigas grown under identical conditions in the strait of Georgia. The proportions of glycogen and protein are shown to be approximately reciprocal and the greatest variation to occur during the summer. The energy content varies slightly, attaining a maximum in late fall and early winter, O. gigas having the highest and O. lurida the lowest values.

Marketable Fruit

Strawberry (Fragaria xananassa Duch.) production in subtropical areas is characterized by a low late-fall and early winter fruit yield, a time when the value of the crop is the highest of the season. Under this context, the objective of the present study was to evaluate the feasibility of waiting-bed plants for late fall and early winter production in order to increase early and total fruit yields in the Argentine sub-tropic. Plants of the cultivar `Chandler' produced in a waiting-bed (WB), at high-latitude (HL), high-altitude (HA), or low-altitude (LA) were compared at two locations in Tucuman, NW Argentina: Famailla (1995, experiment 1; 1996, experiment 2) and Lules (1995, experiment 3). Total production from WB plants was 41% higher than from HA plants in experiment 1. Total production from WB plants was 83 % and 53 % greater than from HL plants and LA plants, respectively, in experiment 2. Early season fruit production was greater in WB (241%) than HL plants in experiment 2. In experiment 3, early fruit production from WB plants was greater than HL, HA, and LA, by 573, 177, and 158%, respectively. The number of marketable fruit from WB plants was larger than in the other treatments (139-231%). WB percentages of marketable fruit were above 90%. The results suggest that WB plants could be considered as an alternative to HL, HA, and LA plants to improve strawberry production and yield distribution in South American subtropical regions.

From observations in the field and the results of inoculation experiments it has been discovered that Milesia laeviuscula (Diet. & Holw.) Faull causes a needle rust on the current year's needles of grand fir (Abies grandis (Dougl.) Lindl.). The rust has been induced repeatedly to fruit on both alternate hosts, licorice fern (Polypodium vulgare L. var. occidentale Hook.) and grand fir, by inoculation, and its pycnial and aecial states are described for the first time. The life history of Milesia laeviuscula is presented. It is noteworthy because of the long period (4 to 5 months) required for maturation of the aecia, because primary infection of the fern takes place largely during late fall and early winter, and because the rust can survive on its fern host independent of its alternate host, grand fir.

Point Types

The Jim Pitts site is a multicomponent Paleoindian locality in the Black Hills of South Dakota, with a rare Goshen residential occupation. All Paleoindian components were comprised in the Leonard paleosol. The deepest component at the site is a Goshen level dated to 10,185 ± 25 B.P. It correlates with a late fall-early winter camp site. Over the course of its use parts of at least five bison were procured and introduced to the site. Above this level an array of point styles, including Goshen, Folsom, Agate Basin, several Fishtail points, James Allen, Cody, and Alberta, have also been found. The following study provides a typological and technological description of the point assemblage and weighs the implications of the chrono-cultural stratigraphy for reconstructing the Paleoindian cultural landscape. It questions the validity of some types, particularly Goshen, as cultural and chronological markers. Ultimately, the evidence presented here reinforces a model in which multiple Paleoindian point types occur simultaneously on the central and northern Great Plains. This in turn challenges a unilineal view of Paleoindian culture history.

The Relationship

Data on the activity pattern, proportion of time spent lying and the length of active and lying periods in winter are presented from a 3 year study on the Porcupine caribou herd. Animals were most active at sunrise and sunset resulting in from one (late fall, early and mid winter) to two (early fall and late winter) to three (spring) intervening lying periods. Mean active/lying cycle length decreased from late fall (298 mm) to early winter (238 min), increased to a peak in mid winter (340 min) then declined in late winter (305 min) and again in spring (240 min). Mean length of the lying period increased throughout the 3 winter months from 56 min m early winter to 114 min in mid winter and 153 min in late winter. The percent of the day animals spent lying decreased from fall to early winter, increased throughout the winter and declined in spring. This pattern was related, in part, to day length and was used to compare percent lying among herds. The relationship is suggested to be a means of comparing quality of winter ranges.
