  • A Guide to Frequent and Typical Plant Communities of the European Alps
    - Alpine Ecology and Environments A guide to frequent and typical plant communities of the European Alps Guide to the virtual excursion in lesson B1 (Alpine plant biodiversity) Peter M. Kammer and Adrian Möhl (illustrations) – Alpine Ecology and Environments B1 – Alpine plant biodiversity Preface This guide provides an overview over the most frequent, widely distributed, and characteristic plant communities of the European Alps; each of them occurring under different growth conditions. It serves as the basic document for the virtual excursion offered in lesson B1 (Alpine plant biodiversity) of the ALPECOLe course. Naturally, the guide can also be helpful for a real excursion in the field! By following the road map, that begins on page 3, you can determine the plant community you are looking at. Communities you have to know for the final test are indicated with bold frames in the road maps. On the portrait sheets you will find a short description of each plant community. Here, the names of communities you should know are underlined. The portrait sheets are structured as follows: • After the English name of the community the corresponding phytosociological units are in- dicated, i.e. the association (Ass.) and/or the alliance (All.). The names of the units follow El- lenberg (1996) and Grabherr & Mucina (1993). • The paragraph “site characteristics” provides information on the altitudinal occurrence of the community, its topographical situation, the types of substrata, specific climate conditions, the duration of snow-cover, as well as on the nature of the soil. Where appropriate, specifications on the agricultural management form are given. • In the section “stand characteristics” the horizontal and vertical structure of the community is described.

  • Download Alien Species in Norway
    Alien species in Norway – with the Norwegian Black List 2012 Alien species in Norway – with the Norwegian Black List 2012 presents an overview of ecological impact assessments of alien species which reproduce in Norwegian territories. The assessments are based upon a new and semi- quantitative set of criteria, where the species’ invasion potential and ecological effect are considered. The work has been carried out by 11 groups of experts who have treated ca. 2500 species. Impact assessments have been made for 1180 alien species which reproduce in Norwegian territories and for 134 species which might arrive in Norway with the aid of humans in the future – so called ‘door knockers’. A total of 106 species are categorised as having a severe impact, 111 species as having a high impact, 198 species as having a potentially high impact, 399 species as having a low impact, and 366 species as having no known impact in Norwegian nature. In addition, species inform- ation has been gathered for 1071 alien species which do not reproduce on the Norwegian mainland and territorial waters, and 69 non-reproducing alien species observed in Svalbard.

    The Italian Dolomites Naturetrek Tour Report 23 – 30 June 2016 A hay meadow Lesser Butterfly Orchid Lesser Butterfly Orchid King of the Alps Edelweiss Report by Jessica Turner Images courtesy of Julian Comrie Mingledown Barn Wolf’s Lane Chawton Alton Hampshire GU34 3HJ England T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report The Italian Dolomites Tour participants: Jessica Turner and Luca Sattin (leaders) with 13 Naturetrek clients Introduction The Dolomites are some of the finest mountains in Europe, where a complex mix of geology and habitat supports a great range of plants amidst stunning scenery. We were blessed with generally excellent weather, which meant the flower-filled hay meadows were being cut, but we still found plenty to enjoy, especially the gaudy Orange Lilies which almost seem out of place there. The carpets of orchids were a joy, especially the diminutive Vanilla Orchids, while numerous treasures were found on the rocky mountain slopes. With the hospitality provided by Stefano, Katia and Genio at the Gran Mugon as warm as ever, with excellent, delicious cuisine, everything contributed to a most enjoyable week. Day 1 Thursday 23rd June Flight to Venice, onwards to Tamion Despite a cancelled flight as a result of French industrial action, the Naturetrek staff worked hard to ensure group members travelling from the UK today reached Venice, where we enjoyed good views of the city as we landed at Marco Polo Airport. Here we met with those who had already spent a few days enjoying this charismatic city, and with Luca, who lives nearby.

We conducted parsimony and Bayesian phylogenetic analyses based on nuclear ribosomal DNA internal transcribed spacer and chloroplast trnL intron sequences obtained from 218 of the ca. 255 species of Trifolium, representatives from 11 genera of the vicioid clade, and an outgroup Lotus. We conWrm the monophyly of Trifo- lium, and propose a new infrageneric classiWcation of the genus based on the phylogenetic results. Incongruence between the nrDNA and cpDNA results suggests Wve to six cases of apparent hybrid speciation, and identiWes the putative progenitors of the allopolyploids T. dubium, a widespread weed, and T. repens, the most commonly cultivated clover species. Character state reconstructions conWrm 2n D 16 as the ancestral chromosome number in Trifolium, and infer a minimum of 19 instances of aneuploidy and 22 of polyploidy in the genus. The ancestral life history is hypothesized to be annual in subgenus Chronosemium and equivocal in subgenus Trifolium.

  • The Utility of Barcodes and Sequencing Techniques*

A DNA metabarcoding study of a polyphagous beetle dietary diversity: the utility of barcodes and sequencing techniques. Folia Biologica (Kraków) 62: 223-234. Recently developed techniques of DNA barcoding and next-generation sequencing (NGS) overcome previous limitations of evaluation of animal diet composition and together are promising method in molecular ecology. The objective was to compare standard ABI Sanger sequencing with new high throughput sequencing (Illumina MiSeq) technique and the two selected plant barcodes (rbcL gene and trnL intron) in terms of the identification of host plant composition for the selected beetle species – the Centricnemus leucogrammus weevil. A comparison of two sequencing techniques showed that NGS (in this case Illumina) gave more exhaustive results than the Sanger method. Moreover, it was proven that a two-locus barcoding systems (rbcL and trnL) is sufficient for host plant identification from DNA isolated from insect bodies, at least at the genus level. A comparison of host plant composition among distant populations revealed that the studied species did not feed uniformly across its range. This probably reveals an ecological adaptation of geographically and genetically isolated populations. These findings, beside broadening basic knowledge on the use of barcoding and sequencing techniques for host plant identifications in insect populations, can have implications for conservation studies and strategies for rare and endangered species.
