We aimed to test the hypothesis that a long fruit storage period (i) reduces the final percentage and speed of seed germination, as well as (ii) increases the number of dead seeds among non-germinated ones. We used fruit samples collected in Kraków, southern Poland, in 2013 and 2016, designating two different fruit storage periods of 3.5 years and 0.5 years, under dry, room temperature conditions. Seeds of all the observed species presented remarkably higher final percentage of germination after the short storage period than after the long one. The seeds subjected to the short fruit storage period achieved significantly higher values of Timson’s index and coefficient of velocity, as well as significantly lower values of the mean germination time than samples subjected to the long fruit storage period. After the long storage period, a significantly higher number of dead seeds among non-germinated seeds was found in S. ×niederederi and S. virgaurea. The performed studies showing that the long fruit storage period led to low contribution of germinated seeds in S. ×niederederi and its parental species suggested that the longtime seed desiccation had a negative impact on final germination. Considering that the hybrid can be potentially cultivated for scientific, medicinal or ornamental purposes, the suggested fruit storage period, under dry, room temperature conditions, should be shorter than three years. However, we realize that the response to long storage may vary in different populations and, therefore, further investigations are needed.","PeriodicalId":30223,"journal":{"name":"Biodiversity Research and Conservation","volume":"58 1","pages":"19 - 24"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79149365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model object was a 4-km-long gorge section of the Sopot river valley (80.5 ha), the Central Roztocze Highlands, South-East Poland. Species lists for 40 ca. 200-m-long and 100-350-m-wide sections, according to the river course, separately for the left and right riverbanks, were made. The analysis of the area was based on a 3-meter resolution DEM. We applied primary topographic attributes: slope, and planar, vertical, and total curvatures and also secondary topographic attributes: solar radiation (SRAD) and topographic wetness index (TWI), as well as other terrain characters: denivelation, total, flat and upslope area of each section. Using the multivariate analyses, we analysed relationships between weighted averages of EIVs for each species and topographic attributes. The GIS and DEM became useful tools for the detection of patterns of species with different habitat requirements. The species number correlated positively with the total and flat area of a section and the TWI, while the denivelation, mean slope and upslope area had a reverse vector. Among the most frequent and abundant herb species, we found several spatial patterns of distribution, namely those of: Maianthemum bifolium, Carex remota, C. acutiformis, Filipendula ulmaria, Dryopteris filixmas, and Urtica dioica. The rarest species represented Ajuga genevensis, Scorzonera humilis, and Stachys palustris patterns.","PeriodicalId":30223,"journal":{"name":"Biodiversity Research and Conservation","volume":"6 1","pages":"22 - 9"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91235983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Veratrum album, V. lobelianum and V. nigrum are native to Europe, and in Poland are ranked as rare or threatened. Genetic variation of European Veratrum species was characterized by Amplified Fragment Length Polymorphism (AFLP) markers. The accumulation of jervine as a representative of steroidal alkaloids was measured in seeds. Distribution of 380 markers generated from eight primer combinations was useful for studying genetic relationships among and within species in the Veratrum genus and the most divergent populations were identified. Genetic variation between 12 populations of Veratrum species supports the classification of V. lobelianum as a subspecies of V. album. However, the results need further validation on extended material. A higher genetic diversity (22.3%) was observed between populations of V. nigrum as compared to V. album (14.5%). Contents of jervine allowed for discrimination of the studied Veratrum species and can be used as a potential chemotaxonomic marker. The highest jervine levels were found in V. album. V. nigrum seeds had only trace amounts and no jervine was detected in seeds of V. lobelianum.","PeriodicalId":30223,"journal":{"name":"Biodiversity Research and Conservation","volume":"26 1","pages":"1 - 8"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77281271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, more than 50 formerly exploited areas are known on the islands of Rügen and Wolin. Historical quarry sizes range from 0.1 to 42 hectares, the median is 1.3. Chalk quarries are recolonised by a wide range of species and develop attractive and species-rich communities. To the extent that recolonisation progresses, they act as refugia for rare or local species. Currently, a total of 543 vascular plant species are found in these chalk quarries. Species number ranges from 97 to 218 in thoroughly studied sites, with a median of 138. Of the total floristic inventory, 67% are indigenous species, 18% are archaeophytes and 12% neophytes. Quarries abandoned long ago and remotely situated are home to nearly 90% indigenophytes, whereas those quarries close to settlements or with easy access are tendentially characterised by numerous synanthropic plants. 100 species overall (= 18.4%) belong to Red List categories of Mecklenburg-Western Pomerania. In 22 quarries studied in more detail, Red List percentages show a spectrum from 3.7 to 23.5%, and higher values are found in sites with open habitats and considerable biotope diversity. Among vegetation types, the anthropo-zoogenic heathland and grassland harbours 40% Red List species and occupies the first place concerning nature conservation aspects. A noteworthy percentage of endangered plants is found in fresh-water and bog vegetation, as some quarries are in contact with the aquifer. Succession was and is the impetus for vegetation development. A transect exemplarily demonstrates the vegetation zonation within a chalk quarry and distinguishes headslope, backslope, and footslope and the quarry floor. The respective plant communities are classified into Cornus sanguinea bush stage, Picris hieracioides-Daucus carota community, and basiphilous mesoxerophytic grassland.","PeriodicalId":30223,"journal":{"name":"Biodiversity Research and Conservation","volume":"27 1","pages":"23 - 39"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84356252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, five types of spatial arrangement of C. dioica individuals, depending on their reproduction and living conditions, were established: scattered-diffuse, densely-diffuse, group, spotted and mosaic. Intensive vegetative propagation (often in the absence of seed reproduction) of individuals contributes to the group and spotted spatial structure of population. For low intensity of seed and vegetative reproduction, the arrangement of generative individuals turned out to be scattered-diffuse. Effective generative reproduction of a population was accompanied by a densely-diffuse distribution of individuals, and a combined type of reproduction (effective generative and vegetative) under favourable growth conditions contributes to its mosaic spatial structure. Regardless of the growth conditions, all C. dioica populations were characterised by a left-hand age spectrum which was the result of an effective vegetative renovation of individuals and a stress-tolerant type of strategy of this species. Under optimal growth conditions, the C. dioica populations were characterised by the prevalance of females compared to male ones (2:1), and under stress – a radical change in their sex ratio was observed towards a complete dominance of one of the genders. It was found that 50% of the studied C. dioica populations appeared to be thriving. Regardless of the vitality type of the population, the female individuals of this species, compared to male ones, realised their growth potential much better and, therefore, made a greater contribution to population vitality.","PeriodicalId":30223,"journal":{"name":"Biodiversity Research and Conservation","volume":"41 1","pages":"19 - 33"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74586629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
