Black poplar (Populus nigra L.) is one of the main woody riparian species in Europe. Because of extensive habitat loss due to river regulations, this species is considered rare and threatened. To analyze genetic diversity and spatial genetic structure, we examined ten nuclear microsatellite loci in a population of very old P. nigra trees growing along the Vistula River in Poland. We found a high level of genetic diversity (H E = 0.792, H O = 0.731, A = 14.7) that was within the range of other natural European P. nigra populations, and our results showed that sexual propagation is the dominant way of reproduction in the studied population, leading to high clonal diversity (R = 0.91). Additionally, we did not detect a spatial genetic structure resulting in a random spatial distribution of genotypes. Individuals from such old and diverse populations have the potential to provide valuable reproductive material for both restoration programs and breeding purposes.

“…Even though it is not an economically interesting species, it is of great environmental importance for endangered riparian ecosystems, having in mind that it plays a central role in the development of riparian ecosystems contributing to the natural control of flooding and water quality, and serving as a natural corridor that facilitates gene flow for many riparian species (Storme et al, 2004;Naiman et al, 2005;Jelić et al, 2015).…”

“…If they do occur sporadically in mixed stands, they will be identified as a group of other soft wood species, grouping P. nigra together with P. alba and F. angustifolia. Several research on genetic diversity assessment on Serbian P. nigra population have been done lately (Maksimović et al, 2014;Jelić et al, 2015;Čortan et al, 2016), but we do not have the complete picture of our research area, i.e. a clear picture which would cover both spatial and genetic distribution of selected population.…”

Populus nigra L. is one of the rarest and most endangered tree species in Western and Central Europe. Its genetic diversity is of great importance in enabling a native riparian population to survive and reproduce under changing environmental conditions. The aim of this research was assessment of P. nigra viability in one of the best preserved riparian ecosystems in Europe, Special Nature Reserve "Gornje Podunavlje" (Upper Danube), Serbia. Additionally, the analysis of the genetic diversity was made to support the effective conservation in the future. During our study, we have mapped 931 P. nigra trees, which were used for the assessment of present native population. Furthermore, we used 14 microsatellite markers to assess the genetic structure of this this population. Viability assessment showed considerable occurrence of P. nigra in the research area, even though the results show fragmentation. P. nigra occurs mostly individually or in small groups of trees, and has a non-sustainable age structure due to insufficient or lacking regeneration. Despite the limited size of the studied population, the apparent overall genetic diversity was high (He = 0.759) and comparable to other known native populations of P. nigra along the Danube basin. However, the results also confirmed existence of recent bottleneck effect. Significantly positive and quite high F is value (0.147) was noted, which may be ascribed to the "Wahlund effect" because of the population substructure that was revealed by the STRUC-TURE analysis (K=2). Although results say that coverage of native stands is not so promising, most of selected trees within our research assessed showed good viability with potential for natural reproduction However, the problem is that suitable areas for natural seedling establishment are scarce and with that gene flow is probably limited. The fragmentation of the area must be reduced and isolated stands must be interlinked as there is need to create larger non-fragmented areas.

“…Although, natural populations of P. nigra in the northern part of Serbia are still partially widespread, natural regeneration is very infrequent and remaining solitary old trees prevail. Several recent studies have covered P. nigra populations along European catchments (Smulders et al, 2001(Smulders et al, , 2008aImbert and Lefèvre, 2003;Rathmacher et al, 2009;Jelić et al, 2015), however, there is no information available on lations. In addition, no conservation strategies have been initiated so far.…”

Black poplar (Populus nigra L.) is a keystone species of riparian softwood forests along riversides in vast areas of Europe, Western Asia and Northern Africa. Since the end of the 20 th century, black poplar has been recognized as an endangered species throughout Europe due to the loss of its natural habitat and possible crossbreeding with hybrid poplars. Using twelve nuclear SSR loci, we analysed the genetic structure of four native populations from three river valleys in the northern part of Serbia. All tested loci were highly polymorphic, displaying 8 to 25 alleles per locus, overall 179 detected alleles and an zygosity (overall Ho = 0.703) has been lower than the expected (overall H e = 0.808) in each population, which indicates positive F is > 0 (0.132)). An AMOVA analysis revealed that the highest degree of genetic variation occurred within populations (95.33 %) while the genetic variation between populations was really low (4.67 %). been recorded in the studied populations in Serbia.
