Preoperational spatial representation among preschool children in small-scale space

Creator:: Kozick, Stephanie A.
Abstract:: This study examined the effects of stage of preoperational thought, sex and mode of exploration on preschoolers ability to represent a small-scale model configuration of objects. Forty-eight subjects between the ages of 2 years, 5 months and 5 years, 4 months were classed in spatial conceptualization as either Stage I...

Abstract:: Site 35JA42 represents the first protohistoric village complex excavated in Southwest Oregon. Analyses of animal bones recovered from the site offer the first significant insights into human subsistence behaviors in this region. Although the faunal assemblage is extremely fragmented, detailed zooarchaeological analysis indicates that deer were the primary meat resource...

Photoperiod and the timing of pupping in the Pacific harbor seal (Phoca vitulina richardsi) with notes on reproduction in northern fur seals and Dall porpoises

Creator:: Temte, Jonathan L.
Abstract:: Birth and pupping season records of Pacific harbor seals (Phoca vitulina richardsi) were used in an analysis of photoperiod effect on the timing of birth in this species. Dates and latitudes of births were converted into photoperiods using a photoperiod equation. Sequential dates from parturition were converted into photoperiods and...

Interaction between hazelnut (Corylus avellana L.) shoot development and big bud mite (Phytoptus avellanae Nal. and Cecidophyopsis vermiformis Nal.)

Creator:: Burgess, Jean E.
Abstract:: The influence of environmental and genetic variation in plant morphology and development on eriophyoid bud mite (Phytoptus avellanae Nal. and Cecidophyopsis vermiformis Nal.) behavior, survival and colonization on Corylus avellana L. was studied. The distribution pattern of galled buds was consistent with the observation that mites colonize only those buds...

Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

Creator:: Marsden, Katherine E.
Abstract:: The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

An investigation of the effects of nutritional status on the action of insulin in rainbow trout (Salmo gairdneri)

Creator:: Ablett, Richard F.
Abstract:: Three studies were conducted to evaluate the relationship between insulin and nutritional parameters in rainbow trout. In the first study effects on growth parameters and tissue composition of rainbow trout were investigated following injection of bovine insulin at two dose levels every 48 hr for 56 days. In addition, [¹⁴C]-leucine...

The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...
