    Opis:
    Pinus uliginosa is an interesting taxon from the Pinus mugo complex with controversial systematic position andspecific characteristics, intermediate among P. mugo, P. uncinata and P. sylvestris. The peat-bog pine is rare andprotectedin Poland. All its’ known populations have a relict character andare slightly different from each other. The aim of the present study was comparison of the individuals from the Czarne Bagno of the “Torfowisko pod Zieleńcem” Nature Reserve (Sudetes), determined in the field on the basis of morphological characteristics as Pinus uliginosa, with four samples of this taxon from the northern limits of its range in PolandandGer - many andwith Pinus sylvestris, P. mugo and P. uncinata, to verify morphological andtaxonomic relations between them. The material collected from 30 individuals determined as P. uliginosa, was closest to populations of P. uliginosa from the Bory Dolnośląskie, andto P. mugo from the Tatra Mts., concerning the needle characters. The cone characteristics of P. uliginosa individuals from the Czarne Bagno appeared similar to all other of that taxon. In spite of that, the cone characters first of all differentiate P. uliginosa from P. sylvestris, P. mugo and P. uncinata. The combination of needle and cone morphological characters are a good tool to distinguish P. sylvestris, P. uncinata, P. mugo and P. uliginosa with a very high probability.

    Opis:
    Background: Simple sequence repeats (SSRs) are widespread molecular markers commonly used in population genetic studies. Nowadays, next-generation sequencing (NGS) methods allow identifying thousands of SSRs in one sequencing run, which greatly facilitates isolation and development of new SSRs. However, their usefulness as molecular markers still must be tested empirically on a number of populations to select SSRs with best parameters for future population genetic research. An alternative approach, cheaper and faster than isolation and characterization of new SSRs, involves cross-amplification of SSRs in closely related species. Aims: Our goal was to develop multiplex PCR protocols that will be useful in population genetic studies of Scots pine (Pinus sylvestris L.) and dwarf mountain pine (P. mugo Turra), and possibly other pine species. Methods: We tested 14 chloroplast (cpSSRs) and 22 nuclear (nSSRs) microsatellite markers originally designed for Japanese black pine (P. thunbergii Parl.), P. sylvestris and loblolly pine (P. taeda L.) in four populations of P. sylvestris and P. mugo across different locations in Europe. We designed six multiplex PCRs, which were subsequently screened for their ability to provide repeatable and high quality amplification products using capillary electrophoresis. Results: The transfer rate in our study was similar in both pine species, and it was very high for cpSSRs (93% and 86% for P. sylvestris and P. mugo, respectively) and moderate for nSSRs (59% for both species). We managed to design five well-performing multiplex reactions out of six initially tested. Most of the tested loci were polymorphic. Moreover, the allelic patterns detected at some cpSSRs were species-specific. Conclusions: We provide a set of five multiplexes which can be used in genetic studies of both P. sylvestris and P. mugo. Chloroplast marker PCP30277 is a good candidate for a cheap species diagnostic marker suitable for tracking interspecific gene flow between hybridizing species of P. sylvestris and P. mugo.

    Opis:
    A lichenological inventory was conducted in the pine stands in the south-eastern region of Żerków-Czeszewo Landscape Park. The aim of this study was to recognize the lichen species diversity on the bark of Pinus sylvestris by considering tree age and forest habitat type. In total, 26 species of lichenized fungi were found on the bark of P. sylvestris. The biota comprises common and widespread species in Poland. Tree age positively and significantly influenced the species richness on the bark of P. sylvestris. The suitability of the pine tree age for lichens evident as alpha diversity seemed to be independent from the habitat of the trees. The age of phorophytes strongly affected the presence of Hypocenomyce scalaris. Mixed fresh coniferous forests were characterized by higher beta- and gamma diversity compared to fresh coniferous forests. There was no correlation between the number of species per tree (alpha diversity) and diversification of species composition in relation to the distance between pines. The findings indicate that maintenance of a variety of phorophytes and age-diversified tree stands can prevent impoverishment of the lichen biota in the south-eastern part of Żerków-Czeszewo Landscape Park.
