Data from: Molecular signatures of reticulate evolution within the complex of European pine taxa
<p>Speciation mechanisms, including the role of interspecific gene flow and introgression in emergence of new species, are the major focus of evolutionary studies. Inference of taxonomic relationship between closely related species maybe challenged by past hybridization events, but at the same time it may provide new knowledge about mechanisms responsible for the maintenance of species integrity despite interspecific gene flow. Here, using nucleotide sequence variation and utilizing a coalescent modelling framework, we tested the role of hybridization and introgression in the evolutionary history of closely related pine taxa from <i>Pinus mugo</i> complex and <i>P. sylvestris</i>. We compared the patterns of polymorphism and divergence between taxa and found great overlap of neutral variation within <i>P. mugo</i> complex. Our phylogeny reconstruction indicated multiple instances of reticulation events in the past, suggesting an important role of interspecific gene flow in the species divergence. The best fitting model revealed <i>P. mugo</i> and <i>P. uncinata</i> as sister species with basal <i>P. uliginosa</i> and asymmetric migration between all investigated species after their divergence. The magnitude of interspecies gene flow differed greatly, and it was consistently stronger from representatives of <i>P. mugo</i> complex to <i>P. sylvestris</i> than in the opposite direction. The results indicate the prominent role of reticulation evolution in those forest trees and provide genetic framework to study species integrity maintained by selection and local adaptation.</p>

Figure 2 Neighbor-joining (NJ) topology of the analyzed isopod species based on Kimura 2-parameter distances. Triangles show the relative number of individual's sampled (height) and sequence divergence (width). Red triangles highlight terrestrial species with intraspecific maximum pairwise distances > 2.2%, whereas dark blue triangles indicate freshwater species with such distances. Numbers next to nodes represent non-parametric bootstrap values > 90% (1,000 replicates). Asterisks indicate species not recorded in Germany.
Data for: A database of West European headwater macroinvertebrate stoichiometric traits
<p><strong>Motivation</strong>: Ecological stoichiometry investigates the equilibrium and the fluxes of chemical elements and energy between organisms and their environment. Several studies pointed out the value of integrating stoichiometric traits for a better understanding of the mechanisms behind community and ecosystem processes. Especially in the light of globally changing nutrient levels in freshwater systems, the link of stoichiometric traits to nutrient cycling and trophic interactions can improve our investigations of a species or community response to these changes. Benthic macroinvertebrate assemblages are widely used for biomonitoring in freshwaters, providing a large number of data sets gathering information about their taxonomic diversity at many different spatial and temporal scales. Likewise, an increasing number of large databases gives ready access to information on a variety of macroinvertebrate biological traits. The addition of stoichiometric traits to this pool of available information could thus expand the application of trait approaches and facilitate the study of the links between nutrient cycling and ecosystem functioning.<br> Main types of variables contained: The database contains information on elemental content of 188 taxa, in terms of the major nutrients %C, %N and %P and the corresponding molar ratios C:N, C:P and N:P. We provide calculated taxon mean values as well as the underlying raw data on individual level that was obtained from field sampling, supplemented by a literature research (n=1555, 174 taxa).<br> Major taxa and level of measurements: The database contains information on 188 macroinvertebrate taxa, available at species (n = 33), genus (96), tribe (9), subfamily (6), family (42), order (1) or class (1) levels.<br> Software format: .csv file</p>
Plant cover and plant-pollinator interactions in Central European grasslands (Poland/Czech Republic)
<p><span>C</span>omplex 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 of plant-pollinator interactions. In traditional hay meadows and intensive pastures in Central Europe, we contrasted the taxonomic and functional group diversity and composition, the structure of plant-pollinator interactions and the roles of individual species in networks. We found mostly lower taxonomic and functional diversity of plants and insects in intensive pastures, as well as strong compositional differences among the two grassland management types. Intensive pastures were dominated by a single plant with a specialized flower structure that is only accessible to a few pollinator groups. As a result, intensive pastures have lower diversity and specificity of interactions, higher amount of resource overlap, more uniform interaction strength and lower network modularity. These findings stand in contrast to studies in which plants with more generalized flower traits dominated pastures. Our results thus highlight the importance of the functional traits of dominant species in mediating the consequences of intensive pasture management on plant-pollinator networks. These findings could further contribute to strategies aimed at mitigating the impact of intensive grazing on plant and pollinator communities.</p>
