“…Thus, shorter plants tend to form larger inflorescences compared to their total height, these plants being found at high densities. The density of the orchids on grassland patches correlates with the vegetation height [26]. However, regardless of the density of Spiranthes, the length of the inflorescence is more susceptible to modifications than the total height of the plant, this being a characteristic that is influenced by both the density of Spiranthes and the height of the vegetation.…”

There are few reports related to the presence of Spiranthes spiralis in the Oltenia region in southern Romania. This study develops the information concerning the presence of this type of orchid in Gorj County. The studies on the populations of this orchid species have been conducted in the Natura 2000 site of the Community ROSCI0045 Jiului Corridor. In the researched territory, during the investigations, twelve populations of Spiranthes spiralis were sampled for the first time. In 2022–2023, we studied the distribution of this species and assessed its population densities. Our observations indicate that it is a relatively widespread species in the studied area and its populations are more abundant in meadows, in the Medicagini minimae–Festucetum valesiacae plant community.

Due of the potential of species to determine ecosystem properties, it is important to understand how species abundance influences community assembly. Using vegetation surveys on 35 dry grasslands in north-east Slovenia, we defined dominant (8) and subordinate (61) plant species. They were compared on 14 traits to test for differences in community-weighted mean (CWM) and functional diversity (FD). We found that dominants and subordinates differed strongly in their functional traits. Dominants showed higher leaf dry matter content and a more pronounced stress tolerance strategy and were all clonal with a large proportion of species with rhizomes and a rich bud bank, while other species showed a higher specific leaf area, a longer flowering period and more ruderals. For most traits, FD was higher in subordinates. Our results suggest that dominants drive community structure by limited susceptibility to non-competitive processes. Dominants may have positive effects on subordinates by mitigating environmental stressors. Subordinates are able to assemble together by being dissimilar and use different fine-scale niches that are engineered and homogenised by dominants. Our results show that there are fundamental differences in the relative importance of ecological processes between dominant and subordinate plants in species-rich grasslands, which is also important for their conservational management.
