    Letter (copy) From: George Winter, Peru, September 4, 1839 ("memoranda when I was at Peru, 1st") To: D. AL (unsigned), 3 p. (one sheet, folded; handwritten) Comments on the human condition and a spirit of initiative. Man is naturally active and suffers from indolence. Somewhat snide comments on Peru, but praise for the landscape and some buildings, including the courthouse. Musings on canal travel (canal passes through Peru) as slow, conducive to thought, but also confining. He misses the company of the ladies he was with before embarking. The canal boat's horn was excessively audible at his host's house.On verso: fragmentary pencil notes of visit to Frances Slocum and events leading up to it, probably written on the spot, including some items not mentioned in his Journal

    The Effect of Dressing Style on Vitamin D Level in Winter

    Aim: The aim of this study is to determine the effect of covered dressing style on serum vitamin D levels. Material and Methods: The first group consists of 32 women dressing covered style except hands and face during summer and winter seasons and the second group consists of 22 women dressing head and extremities-distal extremities uncovered style during summer. Participants were living in Istanbul. Blood samples were taken between November and March. Milk, cheese, yoghurt, fish and egg consumptions, direct sun light exposures have been questioned. Serum levels of 25(OH)D vitamin, alkaline phosphatase, calcium, phosphorus have been measured. Results: Mean age was 35.1±5.5 in the first group and 37.1±7.5 in the second group. Mean 25(OH)D vitamin level was 4.8 nmol\L in the first group and 16.8 nmol\L in the second group. 25 hydroxyvitamin D levels were found under normal (20-120mmol/L) in both groups and statistical difference between them was meaningful (p=0.022). There was statistically significant relation between duration of sun exposure and vitamin D levels (p=0.002). Conclusion: Low 25(OH)D vitamin levels in both groups were due to very low syntesis during November-March period. Although there was no difference between two groups in terms of clothing manner during winter season, we have been thought that lower 25(OH)D vitamin levels in first group were due to anti-sunlight effect of clothes dressed up by group members during previous summer period.

    Controls on winter ecosystem respiration in temperate and boreal ecosystems

    Winter CO2 fluxes represent an important component of the annual carbon budget in northern ecosystems. Understanding winter respiration processes and their responses to climate change is also central to our ability to assess terrestrial carbon cycle and climate feedbacks in the future. However, the factors influencing the spatial and temporal patterns of winter ecosystem respiration (Reco) of northern ecosystems are poorly understood. For this reason, we analyzed eddy covariance flux data from 57 ecosystem sites ranging from ~35° N to ~70° N. Deciduous forests were characterized by the highest winter Reco rates (0.90 ± 0.39 g C m-2 d-1), when winter is defined as the period during which daily air temperature remains below 0 °C. By contrast, arctic wetlands had the lowest winter Reco rates (0.02 ± 0.02 g C m-2 d-1). Mixed forests, evergreen needle-leaved forests, grasslands, croplands and boreal wetlands were characterized by intermediate winter Reco rates (g C m-2 d-1) of 0.70(±0.33), 0.60(±0.38), 0.62(±0.43), 0.49(±0.22) and 0.27(±0.08), respectively. Our cross site analysis showed that winter air (Tair) and soil (Tsoil) temperature played a dominating role in determining the spatial patterns of winter Reco in both forest and managed ecosystems (grasslands and croplands). Besides temperature, the seasonal amplitude of the leaf area index (LAI), inferred from satellite observation, or growing season gross primary productivity, which we use here as a proxy for the amount of recent carbon available for Reco in the subsequent winter, played a marginal role in winter CO2 emissions from forest ecosystems. We found that winter Reco sensitivity to temperature variation across space (QS) was higher than the one over time (interannual, QT). This can be expected because QS not only accounts for climate gradients across sites but also for (positively correlated) the spatial variability of substrate quantity. Thus, if the models estimate future warming impacts on Reco based on QS rather than QT, this could overestimate the impact of temperature change
