Climate sensitivity analysis of allergenic taxa in Central Europe with new ecological indicators
The aim of the study is to analyse trends of the pollination season with its duration, start and end dates, as well as trends of the annual total pollen count and annual peak pollen concentration for the Szeged agglomeration in Southern Hungary. The data set covers an 11-year period (1997-2007) incl...

Tartalmi kivonat: | The aim of the study is to analyse trends of the pollination season with its duration, start and end dates, as well as trends of the annual total pollen count and annual peak pollen concentration for the Szeged agglomeration in Southern Hungary. The data set covers an 11-year period (1997-2007) including 19 taxa and seven daily climate variables. Trend analysis is performed on both annual and daily bases. Trend analysis on daily bases is a new approach providing information on the annual cycles of trends. For quantifying the strength of the relationship between the annual cycle of the slope of daily trends of the pollen concentrations and the annual cycles of slopes of daily trends of the climate variables an association measure and a multiple association measure are introduced. Individual taxa are sorted into three categories according to their climate sensitivities. These are compared with two novel climate change related indicators, namely risk potential and expansion potential due to the climate change. A novel procedure was applied to separate the effect of the past and current weather conditions in influencing current Ambrosia pollen concentration. The potential effect of land use changes on the pollen release of the taxa considered is also discussed using CORINE Land Cover Database. |
