“…Calcareous geological substrates were significant drivers of orchid species diversity in our case. This corroborated the results of previous studies that identified carbonates and their soils as to the most important substrates for the occurrence of terrestrial orchids [18,21,24]. The same can be stated about the Western Carpathians [31,41,42].…”

“…For example, orchid species richness is lower in cold areas compared to warm climatic conditions in temperate regions [17]. At a regional scale, using orchid data from Greece, species richness showed different relations with climatic characteristics in the case of tuberous and intermediate orchids versus rhizomatous orchids [24]. Our results showed strong collinearity of minimal longitude and several variables, such as altitude, temperature, and precipitations, and this may be responsible for the relationship between longitude and orchid richness in our study.…”

“…Longitude and its effect on species richness of orchids is only occasionally mentioned in largeand regional-scale studies. For example, total orchid richness in Greece showed an inversely unimodal trend along a longitudinal gradient [24]. Generally, geographical position expressed by altitude, latitude, and longitude is a proxy for local climatic conditions [17], which are the most substantive ecological variables influencing orchid richness.…”

“…Existing European studies focusing on the relationship between diversity of terrestrial orchids and ecological factors covered mainly broad geographical ranges e.g., [18,21,24], while regional or local studies were less frequent e.g., [25,26]. Fine-scale studies have a potential to be important for better understanding of the association between species richness and environmental variables [13,24]. Their results can contribute to suitable local conservation and landscape management efforts.…”

Orchids are one of the most species-rich families in the world, and many species are under threat in numerous countries. Biodiversity research focusing on the relationship between the richness of orchid species and ecological factors was performed across the Cerová vrchovina Mts (Western Carpathians) testing impact of 26 explanatory variables. We aimed to determine the main ecological predictors controlling species richness and to predict potential species richness patterns. Altogether, 19 orchid species were found in the studied area, with Cephalanthera damasonium and Epipactis microphylla being the most common. Four environmental predictors (minimal longitude, carbonate-containing sediments, maximal yearly solar irradiation, and agricultural land) had statistically significant effects on orchid richness following regression analysis. Predictive models for the nine most frequent species using MaxEnt software showed (i) that land cover and geological substrate had the highest contribution to the explained variance in the models and (ii) strong potential for occurrence of given orchids in several poorly mapped parts of the studied area.

“…As a result, we lack critical information necessary for the conservation of Orchidaceae, especially the species that are known to be threatened or endangered. Therefore, understanding the abundance and distribution patterns of species at large spatial scales is one of the key goals of biogeography and macroecology [7][8][9] . The lack of knowledge about orchid ecology and distribution also negatively affects our ability to identify sites that are worth protecting.…”

Understanding the abundance and distribution patterns of species at large spatial scales is one of the goals of biogeography and macroecology, as it helps researchers and authorities in designing conservation measures for endangered species. Orchids, one of the most endangered groups of plants, have a complicated system of pollination mechanisms. Their survival strongly depends on pollination success, which then determines their presence and distribution in space. Here we concentrate on how pollination mechanisms (presence/absence of nectar) are associated with orchid species density and mean niche breadth along an altitudinal gradient in six different phytogeographical regions in the Czech Republic. We found differences between these regions in terms of orchid species numbers and density. The trend (hump-shaped curve) in species density of nectarless and nectariferous orchids were very similar in all phytogeographical regions, peaking between 300-900 m. The trend strongly depends on habitat cover and pollinator availability. In general, the most specialist species of orchids were found from low to middle altitudes. The association of altitude with the richness of orchid flora is much stronger than that with the biogeography. Climate change is a factor that should not be neglected, as it may affect the presence/absence of many species in the future.

To understand the distribution of biodiversity and its determinants, particularly that of ecologically sensitive ones, has long been intriguing to the science community and will help formulate conservation strategies under future climate changes. To this end, we conducted extensive field surveys on the distribution of orchid flora in the Beipan River Basin in Guizhou Province, which is one of the biodiversity conservation priorities in China. The data we acquired, together with those published previously, were converted into orchid species richness for each of the 3 km × 3 km grid cells covering the study region. Redundancy analysis (RDA) and geographically weighted regression (GWR) were then applied to determine which of the 30 environmental factors are potentially critical for the spatial distribution of orchid flora we have observed. Despite a moderate spatial extent, we found that the Beipan River Basin harbors about 249 native orchid species belonging to 74 genera, equivalent to 14.5% of orchid flora of China. Orchid species richness in this area follows a descending gradient from the southeast to the northwest, 70.41% of its variation among grid cells can be explained by environmental factors and spatial variables, and spatial variables accounted for 63.90% of the spatial variation of orchid distribution, indicating that spatial variables played a dominant role in the distribution of wild Orchidaceae species richness. In addition, the main environmental driver is the mean temperature of the wettest quarter. Our study provides a good example for revealing the main drivers of orchid distribution characteristics and has a certain reference value for the development of orchid conservation strategies.
