Wetland ecosystems are important habitats for the growth and survival of numerous terrestrial orchids in Europe. This study reviews the current knowledge on the orchids of wetland vegetation in the Central Balkans. The orchid flora was analyzed from taxonomic, phytogeographical, ecological and conservation aspects. The most important taxa include t...
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...
Understanding patterns of species diversity along an altitudinal gradient is the major topic of much biogeographical and ecological research. The aim of this study was to explore how richness and density of orchid species and subspecies in terms of different categories of underground organ systems and pollination systems vary along an altitudinal g...
The Balkan Peninsula is considered one of the most important centres of orchid diversity in Europe. However, the patterns of orchid species richness in the Central Balkans have not been sufficiently studied so far. The aim of this study was, therefore, to identify the centres of orchid diversity and the factors that influence the spatial variation...
Main conclusion
Two different strategies for the distribution of macro- and trace elements can be observed in the terrestrial orchid Gymnadenia conopsea. Most trace elements are not translocated to the above-ground parts, whereas for macro-elements the trend was reversed, with the highest accumulation in the distal parts of the plants.

In this article we present and discuss the main factors that threaten natural populations of Cypripedium calceolus (lady's slipper orchid) in Europe, and we propose conservation strategies and directions for protective actions of its population on a regional scale. European C. calceolus populations have decreased significantly in the last two decad...
In the original publication of the article, there were two minor errors identified. They are as follows:
Terrestrial orchids in Europe inhabit a variety of vegetation types, both the forest and scrub types and herbaceous vegetation. The richness and composition of orchid species and subspecies in relation to vegetation types in the central Balkans (western Serbia) were investigated in the present study. In total, the phytocoenological affiliation of 5...

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...
The steppe flora and vegetation represents a significant part of the Eurasian temperate grassland biome. In Serbia, this flora is a part of the biome’s western border zone and its characteristics therefore may be modified. The aim of this study was to determine the number of steppe taxa in Serbia and to conduct a chorological and ecological analysi...
Terrestrial orchids in Europe are known for their great species richness that occurs on calcareous geological substrates. However, the knowledge of orchids that grow on other bedrock types is limited. In this paper, the richness and composition of orchid species in relation to geological substrates in the central Balkans (western Serbia) were inves...
Neottia cordata is an orchid species that exclusively occurs in Picea abies subsp. abies and Pinus sylvestris stands and forms its southernmost distribution limits in Greece. Over the last decade, it has been recorded in numerous sites, in which it forms small colonies, both in terms of population and area. This research re-evaluates the threat sta...

The aim of this study was to determine the photosynthetic and antioxidant response of the
orchid Anacamptis morio to chemical properties of carbonate, ultramafic and siliceous (chert)
soils. Acidic soil solution and the lowest amount of organic carbon were characteristic of siliceous
soils, whereas toxic amounts of Co, Cr and Ni were measured in ul...
The pollination success of two nonrewarding orchids in two coarse habitats was examined. The comparative results of Orchis punctulata and O. purpurea showed a significant differentiation. The fruit set of O. purpurea was significantly greater compared to O. punctulata, whereas both species also had significantly higher fruit set in the grassland co...
Along with being a centre of plant species diversity and endemism, the Balkan Peninsula is one of the parts of Europe with the highest number of orchid taxa. However, the orchid flora in the central Balkans has not been sufficiently studied. The paper presents the distribution of ten rare and threatened taxa of Orchidaceae in the central Balkans an...
Orchids are known for their species richness, intriguing ecology, rarity and the fact that they grow in almost all terrestrial ecosystems. Although numerous studies about their ecology have been carried out concerning calcareous areas, little is known about orchids that occur in serpentine habitats. The aim of this study was to investigate the ecol...
Epipactis muelleri Godfery (Orchidaceae-Epidendroideae-Neottieae) was

limit of its distribution in the Balkans, where it has recently been known only from
two other countries (Slov...
Grasslands, wet meadows, fens, bogs, and marshes represent important ecosystems that host many orchid species.
