Paleobotanicka data pokrývaji obdobi od pozdniho glacialu do pozdniho holocenu. Vsechny druhy považovane za glacialni relikty se opravdu vyskytovaly v pozdně glacialnich sedimentech, ale větsinou ve stejných oblastech, odkud byly zaznamenany botanickým výzkumem od 19. stoleti. Některe oblasti se tedy vyznacuji castějsim výskytem těchto druhů v minulosti i v soucasnosti. V některých připadech se ale studovane druhy vyskytovaly během pozdniho glacialu nebo raneho holocenu i v oblastech, kde už se dnes nevyskytuji z důvodu nevhodných podminek prostředi. Rovněž jsme zjistili, že celkový pocet pozdně glacialnich a raně holocennich výskytů studovaných druhů výrazně převysuje pocet jejich výskytů ve střednim holocenu, kdy casto probihala sukcese k mokřadnim lesům nebo vrchovistim.

Tento hybrid, který dosud neměl dvouslovne jmeno, byl předtim nalezen jen jednou v pasmu jižnich vapencových Alp při rakousko-slovinske hranici v Karavankach, kde se oba velmi vzacne rodicovske druhy dostavaji ojediněle do kontaktu. Jedinou dalsi takovou oblasti jsou patrně Ennstalske Alpy, ležici v pasmu severnich vapencových Alp. Pravě zde pobliž osady Kolblwirt jsme nalezli ctyři jedince vykazujici intermediarni habitus. Podrobnějsi rozbor morfologických znaků ani analýza velikosti genomu pomoci průtokove cytometrie hybridni status těchto jedinců nevyvratily. U casto hybridizujicich pchaců je nicmeně vždy namistě urcita opatrnost, protože „hybridni“ nažkymohou být, např. diky chmýru, transportovany i poměrně daleko od mista sveho vzniku. Abychom bezpecně identifikovali původ hybridnich rostlin, rozhodli jsme se pomoci AFLP analyzovat nejen oba potencialni rodicovske druhy a s nimi spolu na lokalitě rostouci C. erisithales, ale i vsechny dalsi druhy pchaců, rostouci v rakouske casti východnich Alp: C. acaulon, C. arvense, C. eriophorum, C. heterophyllum, C. oleraceum, C. palustre, C. pannonicum, C. rivulare, C. spinosissimum a C. vulgare. Analýza STRUCTURE předpokladaný původ hybridů potvrdila a vizualizace pomoci sitě NeighborNet navic ukazala, že jsou nejpřibuznějsi pravě s jedinci C. carniolicum a C. greimleri pochazejicimi z lokality u Kolblwirt, takže vznikly zde a ne transportem „hybridnich“ nažek odjinud. V jedine rostlině (klonu) C. greimleri na teto lokalitě byla pomoci STRUCTURE odhalena mirna introgrese C. erisithales. U hybridů byla vsak přislusnost k C. erisithales prakticky zanedbatelna. Tato skutecnost ma dvě alternativni vysvětleni: buď (i) byly gamety rodicovskeho mirně geneticky erodovaneho C. greimleri nahodnou meiotickou segregaci homeolognich chromozomů „vycistěny“ od alel C. erisithales, nebo (ii) jsou jak hybridi, tak i v ramci lokality jedine, mirně geneticky erodovane, C. greimleri potomky tehož jedince – cisteho C. greimleri – který na lokalitě vyhynul. Geneticky jsou tedy jedinci C. ×sudae křiženci mezi C. carniolicum a C. greimleri a ne trojnasobni hybridi. Nejnapadnějsimi znaky tohoto noveho hybrida jsou velke, mělce lalocnate listy s měkkými ostny a siroce vejcitou cepeli u nejspodnějsich z nich (jako u obou rodiců) a take jeho růžově bile květy (intermediarni mezi oběma rodici).

How long the seed persists depends on its physical and physiological characteristics as well as on biotic and abiotic environmental conditions. In alien species, the ability to develop a persistent seed bank is associated with their ability to naturalize and become invasive. We carried out an experiment to find out how long the seeds of Heracleum mantegazzianum, one of the most invasive monocarpic species in Europe, are able to persist in soil and explore the effect of environmental conditions on seed depletion over a long period of time. The seeds were buried at 10 localities in different regions of the Czech Republic to cover a range of climatic, edaphic and geographic conditions. After seven years of burial, 0.1% of the seed of H. mantegazzianum, averaged across the localities, were viable, and none survived at five localities, at one of which the seed bank was completely depleted after five years and at one already after two years. The highest recorded survival at the end of the burial period was 0.5% of seed. In general, the average seed-bank survival was very low after five years and never exceeded 1%. We found a significant correlation between the percentage seed bank depletion and the content of total carbon and organic carbon; the effects of other soil characteristics, climatic and geographical factors were not significant. High percentages of seed persisted after the first year at localities with a low carbon content but the percentage depletion after seven years was slower at localities with a high carbon content. In addition, low carbon content and high seed survival after the first year was recorded at localities with nutrient poor soils. The course of seed bank depletion in H. mantegazzianum corresponds to its classification as short-term persistent. Therefore, monitoring well beyond the reported period of seed bank persistence is recommended after full eradication of this species from a site.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85569527","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}

Potamogeton nerviger was described from Lithuania in 1827 as a proper species. Based on morphological and anatomical characters, its interpretation has since varied, ranging from synonymization with other species to identification as different hybrids and intraspecific taxa. Currently, it is universally recognized as the hybrid P. alpinus × P. lucens. Using a combined molecular, morphological and anatomical investigation we re-examined the identity of P. ×nerviger, based on both original and recent plant material. We report a successful amplification and sequencing of nuclear ribosomal ITS1 region from a 188year-old type collection. This was shown to be genetically identical to the morphologically matching plants recently collected at the type locality. Comparison with molecular characters of the possible parental species shows that P. ×nerviger is not P. alpinus × P. lucens, as currently believed, but another hybrid, P. nodosus × P. perfoliatus, which is currently called P. ×assidens. This molecular identification is also supported by anatomical evidence. In contrast, the actual existence of the hybrid P. alpinus × P. lucens is doubtful. Consequences for nomenclature and identities of records reported from other sites are discussed.","PeriodicalId":20501,"journal":{"name":"Preslia","volume":null,"pages":null},"PeriodicalIF":3.4,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87801814","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 values are compatible with Ellenberg indicator values, which were used as a baseline, but extensively revised based on our own field observations, literature, comparison with indicator value systems of other countries and an analysis of taxon co-occurrences in vegetation plots from the Czech National Phytosociological Database. Taxa in the Czech flora missing in the original Ellenberg tables were added. Compared with the original Ellenberg's dataset of indicator values, smaller proportions of taxa were classified as extremely basiphilous, extremely oligotrophic or strictly avoiding saline habitats. The revised values were tested by regressing unweighted site mean indicator values against measured environmental variables. In most cases, prediction of environmental conditions was slightly more accurate with the new Czech indicator values than with the original Ellenberg indicator values.
