This issue includes an article on the 20th anniversary of Alexander von Humboldt Club of the Czech Republic. The mission of the club is to maintain contacts between scientific institutions and researchers in the Czech Republic and Germany and to provide information about the Humboldt scholarhip. Alexander von Huumboldt (1969-1859) was a German naturalist and explorer. His work on botanical geography was the foundation for the field of biogeography. After his death, his colleagues created the Alexander von Humboldt Foundation to continue von Humboldt's support of young scientists.
