Data from: Beech roots are simultaneously colonized by multiple genets of the ectomycorrhizal fungus Laccaria amethystina clustered in two genetic groups

In this study we characterize and compare the genetic structure of aboveground and belowground populations of the ectomycorrhizal fungus Laccaria amethystina in an unmanaged mixed beech forest. Fruiting bodies and mycorrhizas of L. amethystina were mapped and collected in four plots in the Świętokrzyskie Mountains (Poland). A total of 563 fruiting bodies and 394 mycorrhizas were successfully genotyped using the rDNA IGS1 (intergenic spacer) and seven SSR (simple sequence repeat) markers. We identified two different...

Identification of determinants of pollen donor fecundity using the hierarchical neighborhood model

Igor Chybicki, Andrzej Oleksa & Monika Dering
Individual differences in male reproductive success drive genetic drift and natural selection, altering genetic variation and phenotypic trait distributions in future generations. Therefore, identifying the determinants of reproductive success is important for understanding the ecology and evolution of plants. Here, based on the spatially-explicit mating model (the neighborhood model), we develop a hierarchical probability model that links co-dominant genotypes of offspring and candidate parents with the phenotypic determinants of male reproductive success. The model accounts...

Plant cover and plant-pollinator interactions in Central European grasslands (Poland/Czech Republic)

Demetra Rakosy, Elena Motivans, Valentin Ştefan, Arkadiusz Nowak, Sebastian Świerszcz, Reinart Feldmann, Elisabeth Kühn, Costanza Geppert, Neeraja Venkataraman, Anna Sobieraj-Betlińska, Anita Grossmann, Wiktoria Rojek, Katarzyna Pochrząst, Magdalena Cielniak, Anika Kirstin Gathof, Kevin Baumann & Tiffany Marie Knight
Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure...

Invasive zebra mussel (Dreissena polymorpha) threatens an exceptionally large population of the depressed river mussel (Pseudanodonta complanata) in a postglacial lake

Małgorzata Ożgo, Maria Urbańska, Philipp Hoos, Hannes Imhof, Malgorzata Kirschenstein, Julia Mayr, Florian Michl, Rafał Tobiasz, Marie Von Wesendonk, Stefan Zimmermann & Juergen Geist
Freshwater mussels are in decline worldwide, with the depressed river mussel Pseudanodonta complanata being one of the rarest and most endangered species in Europe. Invasive mussels are suspected to be an important factor of decline, but there is little information on their interaction with native species. This study analysed densities, depth distribution and individual sizes and weights in one of the largest known populations of P. complanata in Europe in relation to the co-occurring invasive...

Type of broadleaf forest matters most for ptyctimous mite communities (Acari, Oribatida) in Norway

Anna Seniczak, Wojciech Niedbała, J. Carlos Iturrondobeitia, Stanisław Seniczak, Steffen Roth & Bjarte H. Jordal
We studied ptyctimous moss mites, which are characteristic of forest habitats, in Norwegian broadleaf forests considered as biodiversity hotspot areas in Fennoscandia. The study aimed to evaluate the effect of different factors (regional locality, annual precipitation, mean annual temperature, forest type, forest wetness and microhabitat) on the ptyctimous mites and on discovering their richness in broadleaf forests. Samples were collected from nine broadleaf forests in western, southern and eastern Norway, in different climatic conditions, six...

A forest pool as a habitat island for mites in a limestone forest in Southern Norway

Anna Seniczak, Stanislaw Seniczak, Radomir Graczyk, Sławomir Kaczmarek, Bjarte H. Jordal, Jarosław Kowalski, Per Djursvoll, Steffen Roth & Thomas Bolger
Forest water bodies, e.g., pools, constitute ‘environmental islands’ within forests, with specific flora and fauna thus contributing considerably to the landscape biodiversity. The mite communities of Oribatida and Mesostigmata in two distinctive microhabitats, water-soaked Sphagnum mosses at the edge of a pool and other mosses growing on the medium-wet forest floor nearby, were compared in a limestone forest in Southern Norway. In total, 16,189 specimens of Oribatida representing 98 species, and 499 specimens of Mesostigmata,...

Data from: Relative strength of fine-scale spatial genetic structure in paternally vs biparentally inherited DNA in a dioecious plant depends on both sex proportions and pollen-to-seed dispersal ratio

Igor J. Chybicki, Monika Dering, Grzegorz Iszkuło, Katarzyna Meyza & Jan Suszka
In plants, the spatial genetic structure (SGS) is shaped mainly by gene dispersal and effective population density. Among additional factors, the mode of DNA inheritance and dioecy influence SGS. However, their joint impact on SGS remains unclear, especially in the case of paternally inherited DNA. Using theoretical approximations and computer simulations, here we showed that the relative intensity of SGS measured in paternally and biparentally inherited DNA in a dioecious plant population depends on both...

Biometric conversion factors as a unifying platform for comparative assessment of invasive freshwater bivalves

1. Invasive bivalves continue to spread and negatively impact freshwater ecosystems worldwide. As different metrics for body size and biomass are frequently used within the literature to standardise bivalve related ecological impacts (e.g. respiration and filtration rates), the lack of broadly applicable conversion equations currently hinders reliable comparison across bivalve populations. To facilitate improved comparative assessment amongst studies originating from disparate geographic locations, we report body size and biomass conversion equations for six invasive freshwater...
