Premise: The successful establishment of polyploid species is hypothesized to be promoted by niche differentiation from the parental species or by range shifts during climate oscillations. However, few studies have considered both of these factors simultaneously. We resolved the origin of a tetraploid fern, Lepisorus yamaokae, and explored a pattern of niche differentiation among the allotetraploid and parental species in past and current climates. Methods: We reconstructed phylogenetic trees based on plastid marker and singlecopy nuclear genes to resolve the allopolyploid origin of L. yamaokae. We also evaluated climatic niche differentiation among L. yamaokae and its two parental species using species distribution models in geographic space and principal component analysis. Results: We infer that L. yamaokae had a single allotetraploid origin from L. annuifrons and L. uchiyamae. Climatic niche analyses show that the parental species currently occupy different niche spaces. The predicted distribution of the parental species at the Last Glacial Maximum (LGM) suggests more opportunities for hybridization during the LGM or during other recent temporary range shifts. Lepisorus yamaokae has a narrower niche than the additive niche of the parental species. We also observed niche conservatism in L. yamaokae. Conclusions: Range shifts of the parental species during climatic oscillations in the Quaternary likely facilitated the formation and establishment of L. yamaokae. Further, the genetic intermediacy of L. yamaokae may have enabled a niche shift in its microenvironment, resulting in its successful establishment without a macroclimatic niche shift in L. yamaokae.

“…Information on the patterns of genetic diversity in relict trees can help elucidate how these species adapt to climate changes in the long term (Holderegger and Wagner 2000;Yang et al 2015). To date, only a few genetic studies exist on the genus Petrocarya (Sugahara et al 2017), and only two studies have investigated the phylogeny and phylogeography of P. fraxinifolia in the Transcaucasia and Hyrcanian regions (Maharramova 2016;Mostajeran et al 2017).…”

Riparian trees, especially relict trees, are attractive and important for research to understand both past and recent biogeographical and evolutionary processes. Our work is the first study to elucidate the genetic diversity and spatial genetic structure of the canopy-dominating riparian (Juglandaceae) along two altitudinal gradients in different river systems of the Hyrcanian forest, which is one of the most important refugium of relict trees in Western Eurasia. Altitudinal gradients were chosen along two river systems at 100, 400 and 900 m a.s.l. Leaf samples were collected from 116 trees, and the genetic diversity was evaluated with eight SSR markers. Overall, 39 alleles were identified for all of the populations studied. The observed heterozygosity (Ho) varied from 0.79 to 0.87 (with a mean of 0.83). The results of the AMOVA analysis indicated that the variation within populations was 88%, whereas the variation among populations was 12% for all of the gradients. A structure analysis indicated that 93% of the trees were grouped in the same gradient. The genetic distance based on Fst confirmed the structure result and indicated a high rate of gene flow among the investigated populations. Based on high gene flow (low differentiation of the population along the same river) and the clearly distinct genetic structure of the investigated gradients, it can be concluded that rivers are the main seed dispersal vector among populations. The genetic diversity of did not show any trend from upstream to downstream. The high level of gene flow and uniform genetic diversity along each river suggest the âclassicalâ metapopulation structure of the species. Pterocarya fraxinifoliaP. fraxinifoliaP. fraxinifolia

The article presents the results of the study of the invasive potential of K. Koch on the territory of the Botanical Garden - Institute of the Far Eastern Branch of the Russian Academy of Sciences (BSI FEB RAS). Since 2015, we have observed the emergence of self-seedlings of M. sieboldii in natural ecosystems. This invasive population has a heterogeneous structure and morphometric parameters. Our results show the dependence of the mass appearance of seedlings on phenological shifts caused by modern climatic changes. We used a method of modeling potential habitats to describe changes in the boundaries of the natural range for the period from the last glacial maximum to the future in the short term (2070). A tendency for expansion of M. siebo ldii range in the northeastern direction, including potential to distribution of this species over the territory of the Russian Far East has been established.
