“…Mean value of percentage of polymorphic loci (Table 1) of Seaside populations was much lower (47.8%) than Nemunas basin (60.9%) and Lielupė basin (64.3%). It was in agreement with river basin related differentiation of Lithuanian populations of Nuphar luteus (Vyšniauskienė et al, 2020). In addition, our results were in support to genetic data about geographicaly and hydrologicaly isolated basins with Flemish populations of Iris pseudacorus (Lamote et al, 2002) as well as in support to microsatellite data between Spartina alterniflora populations in Japan, with clearly different genotypes of the populations in each out of 4 rivers (Maebara et al, 2020).…”

“…The overall level of genetic variation between populations of L. salicaria that we observed (Φ PT = 0.213; Table 2), was within the range reported for Lithuanian Phragmites australis (Naugžemys et al, 2021), and Nuphar lutea populations (Vyšniauskienė et al, 2020). Employing hierarchic AMOVA, several cases of population grouping were used to determine which of these different groups would give the highest discrimination among populations.…”

“…Nevertheless, riparian species or population genetic diversity remains fragmentaly analyzed. In parallel to present assessment, several pilot studies were performed describing genetic differentiation between Lithuanian populations of some common, invasive or rare macrophytes, like Impatiens glandulifera (Kupcinskiene et al, 2015) I. parviflora (Kupcinskiene et al, 2015), Nuphar lutea (Vyšniauskienė et al, 2020), Phalaris arundinacea (Anderson et al, 2018), Bidens sp.

“…Already three decades molecular methods remain among the most reliable tools for information sets about population diversity issues (Guichoux et al, 2011). Inter simple sequence repeats (ISSR), microsatellites (SSR) and amplified fragment length polymorphism (AFLP) markers are the most frequently used tools for examination of genetic diversity of populations of macrophytes (Lambertini et al, 2010;Anderson et al, 2018;Vyšniauskienė et al, 2020;Fan et al, 2021), as well as for detection of introgression (Bradley et al, 2013;Butkuvienė et al, 2017), linking phenotyphic plasticity to genetic variation (Wennersten & Forsman, 2012;Forsman, 2014). Before initiation of present study, American populations of L. salicaria were tested employing AFLP markers, and related data concerning genetic diversity of this species in Europe were limited to West regions (Houghton-Thompson et al, 2005;Chun et al, 2009).…”

The present study evaluated genetic diversity of Lithuanian populations of Lythrum salicaria in relation to parameters of riparian environment. Growing along Nemunas, Seaside and Lielupė river basins, 15 populations were examined using amplified fragment length polymorphism markers. Molecular data were related to the river basins, type of land use and cover, natural vice versa regulated fragments of the rivers. Population mean genetic diversity parameters were as follows: percentage of polymorphic loci (57.2), expected heterozygosity (0.183), polymorphismc information content (0.218). Mantel test revealed correlation (R2 = 0.0986, p = 0.01) between genetic and geographic distance of populations. Greater genetic diversity within, rather than among populations (ΦPT = 0.213) was observed. According to the Bayesian clustering, studied populations are admixtures of two gene pools. Analysis of molecular variance revealed significant differentiation between populations belonging to distinct river basins, between populations from natural vs. regulated fragments of the rivers.

“…Small and isolated populations are affected by founder effects or genetic drifts, which increase genetic differentiation (Wei et al, 2013;Wu et al, 2019;Xia et al, 2020). Strong genetic differentiation was observed among the Lithuanian river populations of Nuphar lutea (Vyšniauskienė et al, 2020), the invasive Eurasian Myriophyllum populations (Thum et al, 2020), the Batrachium bungei populations growing in the rivers of the Hengduan Mountains in China (Wang et al, 2010), and those of Iranian Stuckenia . In this research, the populations of Zannichellia are differentiated and structured, corresponding to topographic barriers (Alborz, Zagros, and Karkas Mountains) and ecological features.…”

Zannichellia L. (Potamogetonaceae) is a widespread aquatic genus that is distributed in temperate and subtropical aquatic ecosystems worldwide. Because the biogeographical location of Iran includes mountain ranges and deserts that may cause different habitat types, it was assumed that these Zannichellia populations would be stronger differentiated than observed in Zannichellia from temperate regions. The present study aimed to test whether Z. palustris would demonstrate high levels of genetic differentiation over long distances and across mountain ranges. The genetic structure of the populations of Zannichellia was investigated using inter simple sequence repeats (ISSR) and sequence-related amplified polymorphism (SRAP) as molecular markers. The results demonstrated overall high levels of genetic differentiation among populations (GST = 0.53) and isolation by distance. Bayesian assignment analysis at the population level grouped individuals into eight genetic clusters (K = 8) that largely correspond to the topographic barriers. Alongside the same mountain ridge, the freshwater and saltwater habitat differences corresponded to Z. palustris var. palustris and Z. palustris var. pedicellata, respectively. Our results support the hypothesis of isolation by distance. This high level of genetic differentiation argues for a conservation strategy to maintain a diversity of populations of Zannichellia in mountainous regions.

Genetic drift versus natural selection affecting the evolution of spectral and functional traits of two key macrophytes: Phragmites australis and Nuphar lutea

Both genetic and phenotypic intraspecific diversity play a crucial role in the ecological and evolutionary dynamics of organisms. Several studies have compared phenotypic divergence (Pst) and differentiation of neutral loci (Fst) to infer the relative roles of genetic drift and natural selection in population differentiation (Pst–Fst comparison). For the first time, we have assessed and compared the genetic variation and differentiation at the leaf trait level in two key macrophytes, Phragmites australis and Nuphar lutea. To this aim, we quantified and described the genetic structure and phenotypic diversity of both species in five lake systems in north‐central Italy. We then investigated the relative roles of genetic drift and natural selection on leaf trait differentiation (Pst–Fst), assuming that Fst reflects divergence caused only by genetic drift while Pst also incorporates the effects of selective dynamics on the phenotype. In terms of genetic structure, the results for P. australis were in line with those observed for other Italian and European conspecific populations. Conversely, N. lutea showed a more complex genetic structure than expected at the site level, probably due to the combined effect of genetic isolation and its mixed mating system. Both species exhibited high variability in leaf functional traits within and among sites, highlighting a high degree of phenotypic plasticity. Pst–Fst comparisons showed a general tendency towards directional selection in P. australis and a more complex pattern in N. lutea. Indeed, the drivers of phenotypic differentiation in N. lutea showed a variable mix of stabilising and directional selection or neutral divergence at most sites. The prevalence of vegetative over generative reproduction leads P. australis populations to be dominated by a few clones that are well adapted to local conditions, including phenotypes that respond plastically to the environment. In contrast, in N. lutea, the interaction of a mixed mating system and geographical isolation among distant sites tends to reduce the effect of outbreeding depression and provides the genetic basis for adaptive capacity. The first joint analysis of the genetic structure of these two key macrophytes allowed a better understanding of the relative roles of genetic drift and natural selection in the diversification of phenotypic traits within habitats dominated by P. australis and N. lutea.
