Article
Full-text available
Many terrestrial orchid species are known to grow in forest ecosystems, but the patterns of their diversity and habitat specialization have not been sufficiently explored. Niche parameters and factors influencing the distribution, abundance and composition of forest orchids in the central Balkans were investigated in the present study. Outlying mea...
Chapter
The Balkan Peninsula is one of the most important centers of orchid diversity in Europe. However, the orchid flora in the central Balkans and southern part of the Pannonian Plain is still not sufficiently known. Therefore, this chapter reviews the orchid flora of Serbia, considering its taxonomic structure, life forms, and pollination systems. More...
Chapter
Distributed throughout the continents, terrestrial orchids are known for their great species richness and specificity in relation to pollinators and mycorrhizal symbionts. Moreover, a large number of them are rare and sensitive to environmental changes. This chapter is mainly focused on the terrestrial orchids of Europe and reviews the major enviro...

Biotic interactions play an important role in species distribution models, whose ignorance may cause an overestimation of species' potential distributions. Species of the family Orchidaceae are almost totally dependent on mycorrhizal symbionts and pollinators, with sexually deceptive orchids being often highly specialized, and thus the interactions...
