The objective of this paper is to assess the relationship between the cereals cultivated in the Late Bronze and Early Iron Ages (ca. 1250–400 BC) within the area of the present-day Czech Republic, and their environmental settings. The various charred caryopses of cereal species represented in the archaeobotanical assemblages from 35 archaeological sites differ, especially in the proportion of wheat and barley. The cereal assemblages were compared regarding site altitude, weather conditions, soils and soil productivity. The most important environmental variable influencing the choice of a particular crop seemed to be altitude which is correlated with other variables such as the length of growing season, mean annual temperature, soil quality etc. Although the ecological requirements of cereals cultivated in the Late Bronze and Early Iron Ages are not known, they presumably thrived under similar conditions to present-day species/varieties, and the strategy of past crop husbandry was based on similar principles as today, e.g. flexible adaptation to local environmental conditions, in an effort to achieve optimal yields and reduce the danger of crop failure. 相似文献

The process of globalization is increasing competition between urban areas for the attraction of investment. Within this context the paper initially highlights the impact of global change on city economies linking this to international investment within the real estate market. Factors influencing diversification strategies and international investment activity within property markets in central Europe are considered relative to a range of performance criteria. Office markets in Prague, Budapest and Warsaw are forwarded as case study examples to assess the degree of maturity that is occurring in these former socialist cities based on the activity of investors and end‐users including the extent to which there are dual markets operating for local and international actors. 相似文献
