Morphological and Anatomical Differentiation of in Relation to the Presence of Invasive Species : A Case Study from Vlasina Lake, Serbia.

represents non-native and highly invasive species in Europe that significantly influence freshwater plant communities by decreasing the diversity of native species. This study aimed to determine whether the morphological and anatomical features of , a native species in Vlasina Lake, differ between sites where it coexists with and those where is not present. Environmental variables such as water depth, temperature, pH, conductivity, saturation, and O concentration were included in the analysis.

Disentangling Series and Its Polyploids.

Spring crocuses, the eleven species within series (Iridaceae), consist of di- and tetraploid cytotypes. Among them is a group of polyploids from southeastern Europe with yet-unclear taxonomic affiliation. Crocuses are generally characterized by complex dysploid chromosome number changes, preventing a clear correlation between these numbers and ploidy levels.
