{"title":"Postglacial history and current population genetic diversity of a central-European forest plant Hacquetia epipactis","authors":"Jacek Urbaniak, P. Kwiatkowski, M. Ronikier","doi":"10.23855/PRESLIA.2018.039","DOIUrl":"https://doi.org/10.23855/PRESLIA.2018.039","url":null,"abstract":"In the last decade, phylogeographical investigations have significantly contributed to our knowledge of the Quaternary history of several European species of trees in building forest ecosystems. In contrast, the phylogeography of midor low-altitude woodland understorey species that grow in moist and shaded forest habitats is still poorly understood. Here we focus on Hacquetia epipactis, a rare forest component of various types of deciduous forest communities, associated with Fagus sylvatica. We studied the genetic structure of populations of H. epipactis employing two molecular marker systems (AFLP fingerprinting and sequencing of several non-coding chloroplast DNA regions) to investigate the relationships among disjunctive groups of populations spanning its entire distribution in Europe (Dinaric Alps, Alps, Carpathians and adjacent Polish lowlands). The main goal of the present study was to explore the phylogeography and identify potential refugia and probable history of the development of the postglacial range of H. epipactis. We attempt to discuss this case study in the context of postglacial migration of forest forming species, especially beech, and postglacial assembly or co-migration of elements of forest communities. The non-coding chloroplast DNA showed a complete lack of genetic differentiation among populations, which may indicate a fast postglacial colonization from a single refugial area. AFLP data show no clear phylogeographical differentiation and indicate close relationships of the Dinaric and Carpathian/Moravian populations with a likely recent origin of the north-easternmost edge populations in Poland accompanied by a strong founder effect. Based on all the evidence, the most plausible scenario is a rapid, postglacial northward expansion from a Dinaric refugium, which concurs with the published postglacial scenario for beech. However, existence of a local refugium in the northern part of the present range is not excluded based on the distribution of genetic groups, which is also in congruence with the hypothetical last glacial history of beech. This suggests a possible shared migration history and role of Fagus expansion as the dominant species for the parallel establishment of Illyricoid species co-occurring in various beech-dominated communities. Limited gene flow among extant populations, due to disjunction and isolation at different spatial scales, is confirmed by significant correlation of genetic (pairwise Fst) and geographical distances.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"59 1","pages":"39-57"},"PeriodicalIF":3.4,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74585524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the spread of an alien \u0000halophyte Cochlearia danica in continental Europe. This species is native to the Atlantic shores \u0000of Europe, has already spread in many countries along roadsides and was recently discovered in \u0000Hungary. We performed a literature review to track the European spread of this species, and \u0000investigated the Hungarian occurrences in detail. Then we determined the ability of this species to \u0000adapt to local soil conditions by means of soil analyses and germination tests using 19 different \u0000NaCl concentrations and alkaline soils. To estimate the rate of spread, we estimated the size of the \u0000four Hungarian populations in 2016 and 2017, and at the same time we measured the number of \u0000flowering stems, number of flowers in an inflorescence, number of seeds per fruit and seed mass. \u0000Cochlearia danica is recorded growing along roadsides in eight countries in continental Europe. \u0000Literature data indicate a rapid spread of this species along European roads, of 62–65 km/year. \u0000In Hungary this species is recorded at four roadside localities characterized by a high soil salt \u0000content. The relationship between NaCl concentration and percentage germination followed \u0000a sigmoidal curve. Germination tests revealed a significant negative effect of NaCl concentration \u0000on germination above 0.5% NaCl, but germination occurred even on extremely saline substrates \u0000with a 2% NaCl concentration. The area of the largest Hungarian population decreased by more \u0000than 99% and that of the second largest population increased by more than 30% between 2016 and \u00002017. Even though this species can adapt to high salinity in the soil, these rapid and marked \u0000changes in population size indicate that the population dynamics of this species may depend on \u0000interactions between the amount of local precipitation and soil type. Our study indicates that we \u0000should expect further occurrences of C. danica along roads.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"30 1","pages":"23-37"},"PeriodicalIF":3.4,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88841963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Erschbamer, P.

One such complex is the mostly diploid and tetraploid cloudberries (Vaccinium uliginosum L. s.l.), which are not only one of the most frequently recorded dwarf shrubs in the Arctic, but also in mountain ranges such as the European Alps. Surprisingly, in spite of its ubiquity there is very little information on variation in ploidy level, habitat and morphology of V. uliginosum s.l. across the Alps and in adjacent areas; also the taxonomic status of V. uliginosum s. str. and V. gaultherioides is controversial. Based on five latitudinal transects sampled across the middle Alpine arc and an integrative approach combining flow cytometry, plastid DNA sequencing, amplified fragment length polymorphism fingerprinting, morphometrics and characterization of ecological niches via phytosociology and Landolt indicator values the following questions were addressed: (i) What is the large-scale distribution of diploid and tetraploid V. uliginosum s.l. in the area sampled? (ii) Are molecular genetic relationships governed by ploidy level differentiation or is there evidence for acrosscytotype gene flow causing geography-correlated clustering? Is there evidence for (iii) ecological or (iv) morphological separation between cytotypes? We revealed that tetraploids occur throughout the area investigated in the Alps and in their northern forelands, whereas diploids appear to be restricted to the Central Alps and the Southern Limestone Alps. The two cytotypes corresponded to two non-overlapping groups in the AFLP data set, and were also in almost perfect congruence with two plastid lineages. The single evidence for gene flow between diploids and tetraploids was a tetraploid individual carrying a haplotype from an otherwise exclusively diploid lineage. Diploids and tetraploids show some degree of niche separation, which is mostly due to the exclusive occurrence of tetraploids at low altitudes; above 1500 m a.s.l. both cytotypes co-occur. Accordingly, tetraploids occur in a broader range of plant communities than diploids. In spite of the clear separation of diploids and tetraploids in the molecular data sets we failed to detect consistent morphological differences. In particular, absolute size characters exhibited a strong inverse correlation with altitude within the tetraploid cytotype, which prevents their use for reliable determination. Consequently, based on the characters employed here, it is currently impossible to morphologically discriminate diploid V. gaultherioides and tetraploid V. uliginosum s. str. in areas where their ranges overlap, i.e. in subalpine and alpine dwarf shrub communities.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":"7 1","pages":"291-308"},"PeriodicalIF":3.4,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91051320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mainland regions with the highest numbers of naturalized aliens are some Australian states (with New South Wales being the richest on this continent) and several North American regions (of which California with 1753 naturalized plant species represents the world’s richest region in terms of naturalized alien vascular plants). England, Japan, New Zealand and the Hawaiian archipelago harbour most naturalized plants among islands or island groups. These regions also form the main hotspots of the regional levels of naturalization, measured as the percentage of naturalized aliens in the total flora of the region. Such hotspots of relative naturalized species richness appear on both the western and eastern coasts of North America, in north-western Europe, South Africa, south-eastern Australia, New Zealand, and India. High levels of island invasions by naturalized plants are concentrated in the Pacific, but also occur on individual islands across all oceans. The numbers of naturalized species are closely correlated with those of native species, with a stronger correlation and steeper increase for islands than mainland regions, indicating a greater vulnerability of islands to invasion by species that become successfully naturalized. South Africa, India, California, Cuba, Florida, Queensland and Japan have the highest numbers of invasive species. Regions in temperate and tropical zonobiomes harbour in total 9036 and 6774 naturalized species, respectively, followed by 3280 species naturalized in the Mediterranean zonobiome, 3057 in the subtropical zonobiome and 321 in the Arctic. The New World is richer in naturalized alien plants, with 9905 species compared to 7923 recorded in the Old World. While isolation is the key factor driving the level of naturalization on islands, zonobiomes differing in climatic regimes, and socioeconomy represented by per capita GDP, are central for mainland regions. The 11 most widely distributed species each occur in regions covering about one third of the globe or more in terms of the number of regions where they are naturalized and at least 35% of the Earth’s land surface in terms of those regions’ areas, with the most widely distributed species Sonchus oleraceus occuring in 48% of the regions that cover 42% of the world area.
