The study of fossil and recent pollen, pollen analysis or palynology, is a branch of botany with an interdisciplinary orientation. Pollen analysis is primarily used to reconstruct the vegetation history of the ice age. It is able to show climatic and anthropogenic influences on the development of the plant cover. Not only botanists, paleoclimatologists and archaeologists benefit from the interdisciplinary orientation of palynology, but also palaeoecologists, geologists, paleontologists, geographers, forest scientists and soil scientists. Furthermore, pollen analysis is applied in bee and honey research, in pollen flight prediction, which is important in the field of allergology, and in criminalistic investigations in federal and state criminal investigation offices. Pollen analytical investigations are mainly carried out on botanisc.
