Abstract :This study describes and assesses the influence of the particular features of microhabitats on the abundances of lichen species. The research was performed in 4 natural reserves: Seaca-Movileni, Badeana, Harboanca-Brahaşoaia, and Balteni insert ignore into journalissuearticles values(all within Vaslui county);. The distribution of lichen species abundances was investigated in 20 cm × 20 cm sampling units at a height of 1 m above the ground. In the studied area 27 lichen species were sampled in 81 sampling units. Cluster analysis indicated both similarities and dissimilarities between the natural reserves investigated. Kruskal-Wallis tests pointed out significant differences regarding tree girths, depth of rhytidome crevices, and relative abundances of the lichen species. The results of a SIMPER test show that Physconia enteroxantha insert ignore into journalissuearticles values(Nyl.); Poelt. and Candelaria concolor insert ignore into journalissuearticles values(Dicks.); Stnr. are the species responsible for the dissimilarities between investigated sites. Mann-Whitney U tests revealed significant dissimilarities between the lichen synusiae investigated. Of all the lichen species recorded, only Physconia enteroxantha and Lecidella elaeochroma insert ignore into journalissuearticles values(Ach.); M. Choisy were significantly correlated with trees of the genus Quercus. There were fewer trees of the genus Quercus with large girths compared to other analyzed tree genera.
