This study estimates demand during the 1980-90 period for wholesale beef cuts by season and by trend. A data set containing monthly nominal prices for wholesale cuts and average choice boxed beef from January 1980 to December 1990 was collected from multiple sources, The approach expressed the change in demand for wholede cuts as the change in the price ratio of individual cuts relative to the ...

Coastal plant communities are being transformed or lost because of sea level rise (SLR) and land-use change. In conjunction with SLR, the Florida Everglades ecosystem has undergone large-scale drainage and restoration, altering coastal vegetation throughout south Florida. To understand how coastal plant communities are changing over time, accurate mapping techniques are needed that can define p...

The seasonal change of bacterial community structure in biofilms on the surface of reed (Phragmites australis) was investigated for about three years (from 2005 June to 2008 March) in Lake Biwa by comparing it with that in surrounding lake water. The community structure in biofilms was different from that in the lake water throughout the seasons and years. The community structure in lake water ...

In temperate European climates, soil water removal due to vegetation transpiration peaks in summer and soil rewetting from higher levels of precipitation occurs in winter. In clays of high plasticity, the seasonal cycles of drying and wetting cause the soil to experience a volumetric change, resulting in seasonal shrinking and swelling. For a clay slope exhibiting volume change, such behaviour ...

The main goal of this study is to use "top-down"? approach to simulate catchment scale hydrologic processes, in terms of water partitioning, runoff generation, storage dynamics and human/water interaction, and therefore to obtain a comprehensive understanding on intra-annual water balance of watersheds. An evaporation model at seasonal scale is developed based on Budyko framework. A runoff gene...

Many plants use the seasonal change in daylength as a signal for flowering. Daylength sensing in Arabidopsis has now been shown to occur by an external coincidence mechanism, which operates by the circadian and light regulation of CONSTANS.
