Data from: Strong indirect herbicide effects on mycorrhizal associations through plant community shifts and secondary invasions

Ylva Lekberg, Viktoria Wagner, Alexii Rummel, Morgan McLeod & Philip W. Ramsey
Million of acres of US wildlands are sprayed with herbicides to control invasive species, but relatively little is known about non-target effects of herbicide use. We combined greenhouse, field and laboratory experiments involving the invasive forb spotted knapweed (Centaurea stoebe) and native bunchgrasses to assess direct and indirect effects of the forb-specific herbicide picloram on arbuscular mycorrhizal fungi (AMF), which are beneficial soil fungi that colonize most plants. Picloram had no effect on bunchgrass viability...

Data from: Suppressing competitive dominants and community restoration with native parasitic plants using the hemiparasitic Rhinanthus alectorolophus and the dominant grass Calamagrostis epigejos

Jakub Těšitel, Jan Mladek, Jan Horník, Tamara Těšitelová, Vojtěch Adamec & Lubomír Tichý
1. Dominance of native or alien competitive plants causes competitive exclusion of subordinate species and represents a major mechanism reducing biodiversity following land-use changes. The successful competitive strategies may however be interfered with by parasitic plants, which withdraw resources from other plants’ vasculature. Parasitism may strongly reduce the growth of the dominants, which may facilitate regeneration of other species and consequently trigger restoration of natural communities of high diversity. 2. Here, we aim to provide...

Data from: Parasite escape through trophic specialization in a species flock

Pascal I. Hablützel, Maarten P.M. Vanhove, Pablo Deschepper, Arnout F. Grégoir, Anna K. Roose, Filip A.M. Volckaert & Joost A.M. Raeymaekers
Adaptive radiation occurs when species diversify rapidly to occupy an array of ecological niches. Since opportunities for parasite infection and transmission may greatly vary among these niches, adaptive radiation is expected to be associated with a turnover of the parasite community. As major agents of natural and sexual selection, parasites may play a central role in host diversification. The study of parasite turnover may thus be of general relevance and could significantly improve our understanding...

Data from: Effects of disturbance frequency and severity on plant traits: an assessment across a temperate flora

Tomas Herben, Jitka Klimesova & Milan Chytry
(1) Recent analyses of plant traits across large sets of species have revolutionized our understanding of plant functional differentiation. However, understanding of ecological relevance of this differentiation is contingent upon knowledge of environmental preferences of species, namely along gradients of disturbance and productivity for which no quantitative data were available until recently. (2) We examined the relationships of key functional traits (life-history categories, leaf-height-seed traits, clonal growth and bud bank traits) in the herb-dominated flora...

Data from: High-resolution and large-extent mapping of plant species richness using vegetation-plot databases

Jan Divíšek & Milan Chytrý
The recent increase in the availability of large vegetation-plot databases has created unprecedented opportunities for analysing and explaining patterns of fine-scale plant species richness across large areas and for individual habitat types. Here we demonstrate how these data can be used to (1) prepare country-wide high-resolution maps of species richness and identify national diversity hotspots for grassland and forest vegetation; (2) compare diversity patterns of all, native, alien and Red List species; and (3) identify...

Data from: Testing the phenotype-linked fertility hypothesis in the presence and absence of inbreeding

Wolfgang Forstmeier, Malika Ihle, Pavlina Opatova, Katrin Martin, Ulrich Knief, Jana Albrechtová, Tomas Albrecht & Bart Kempenaers
The phenotype-linked fertility hypothesis suggests that females can judge male fertility by inspecting male phenotypic traits. This is because male sexually selected traits might correlate with sperm quality if both are sensitive to factors that influence male condition. A recent meta-analysis found little support for this hypothesis, suggesting little or no shared condition dependence. However, we recently reported that in captive zebra finches (Taeniopygia guttata) inbreeding had detrimental effects both on phenotypic traits and on...

Data from: The evolution of dual meat and milk cattle husbandry in Linearbandkeramik societies

Rosalind E. Gillis, Lenka Kovačiková, Stéphanie Brehard, Emilie Guthmann, Ivana Vostrovská, Hana Nohálová, Rose-Marie Arbogast, László Domboróczki, Joachim Pechtl, Alexandra Anders, Arkadiusz Marciniak, Anne Tresset & Jean-Denis Vigne
Cattle dominate archaeozoological assemblages from the north-central Europe between the sixth and fifth millennium BC and are frequently considered as exclusively used for their meat. Dairy products may have played a greater role than previously believed. Selective pressure on the lactase persistence mutation has been modelled to have begun between 6000 and 4000 years ago in central Europe. The discovery of milk lipids in late sixth millennium ceramic sieves in Poland may reflect an isolated...

Data from: White matter alterations in Parkinson's disease with normal cognition precede grey matter atrophy

Ivan Rektor, Alena Svátková, Lubomir Vojtísek, Iva Zikmundova, Jirí Vanicek, András Király & Nikoletta Szabó
Introduction: While progressive MRI brain changes characterize advanced Parkinson's disease (PD), little has been discovered about structural alterations in the earliest phase of the disease, i.e. in patients with motor symptoms and with normal cognition. Our study aimed to detect grey matter (GM) and white matter (WM) changes in PD patients without cognitive impairment. Methods: Twenty PD patients and twenty-one healthy controls (HC) were tested for attention, executive function, working memory, and visuospatial and language...

Data from: Environmental correlates of the Late Quaternary regional extinctions of large and small Palaearctic mammals

Věra Pavelková Řičánková, Michal Horsák, Martin Hais, Jan Robovský & Milan Chytrý
Most studies of mammal extinctions during the Pleistocene–Holocene transition explore the relative effects of climate change vs. human impacts on these extinctions, but the relative importance of the different environmental factors involved remains poorly understood. Moreover, these studies are strongly biased towards megafauna, which may have been more influenced by human hunting than species of small body size. We examined the potential environmental causes of Pleistocene–Holocene mammal extinctions by linking regional environmental characteristics with the...

Data from: Water-borne pharmaceuticals reduce phenotypic diversity and response capacity of natural phytoplankton communities

Francesco Pomati, Jukka Jokela, Sara Castiglioni, Mirdul K. Thomas & Luca Nizzetto
Chemical micropollutants occur worldwide in the environment at low concentrations and in complex mixtures, and how they affect the ecology of natural systems is still uncertain. Dynamics of natural communities are driven by the interaction between individual organisms and their growth environment, which is mediated by the organisms' expressed phenotypic traits. We tested whether exposure to a mixture of 12 pharmaceuticals and personal care products (PPCP) influences phenotypic trait diversity in lake phytoplankton communities and...

Data from: Multi-speed genome diploidization and diversification after an ancient allopolyploidization

Terezie Mandáková, Milan Pouch, Klára Harmanová, Shing Hei Zhan, Itay Mayrose & Martin A. Lysak
Hybridization and genome doubling (allopolyploidy) have led to evolutionary novelties as well as to the origin of new clades and species. Despite the importance of allopolyploidization, the dynamics of post-polyploid diploidization (PPD) at the genome level has been only sparsely studied. The Microlepidieae (MICR) is a crucifer tribe of 17 genera and c. 56 species endemic to Australia and New Zealand. Our phylogenetic and cytogenomic analyses revealed that MICR originated via an inter-tribal hybridization between...

Data from: Trait-dependent distributional shifts in fruiting of common British fungi

Alan C. Gange, Einar Heegaard, Lynne Boddy, Carrie Andrew, Paul Kirk, Rune Halvorsen, Thomas W. Kuyper, Claus Bässler, Jeffrey Diez, Jacob Heilman-Clausen, Klaus Høiland, Ulf Büntgen & Håvard Kauserud
Despite the dramatic phenological responses of fungal fruiting to recent climate warming, it is unknown whether spatial distributions of fungi have changed and to what extent such changes are influenced by fungal traits, such as ectomycorrhizal (ECM) or saprotrophic lifestyles, spore characteristics, or fruit body size. Our overall aim was to understand how climate and fungal traits determine whether and how species-specific fungal fruit body abundances have shifted across latitudes over time, using the UK...

Data from: Monophyletic origin and evolution of the largest crucifer genomes

Terezie Mandáková, Petra Hloušková, Dmitry A. German & Martin A. Lysak
Clade E, or the Hesperis-clade is one of the major Brassicaceae (Crucifereae) clades comprising some 48 genera and 351 species classified into seven tribes and is predominantly distributed across arid and montane regions of Asia. Several taxa have socio-economic significance, being important ornamental but also weedy and invasive species. From the comparative genomic perspective, the clade is noteworthy as it harbors species with the largest crucifer genomes but low numbers of chromosomes (n = 5...
