Robin Pouteau, Idoia Biurrun, Caroline Brunel, Milan Chytrý, Wayne Dawson, Franz Essl, Trevor Fristoe, Rense Haveman, Carsten Hobohm, Florian Jansen, Holger Kreft, Jonathan Lenoir, Bernd Lenzner, Carsten Meyer, Jesper Erenskjold Moeslund, Jan Pergl, Petr Pyšek, Jens-Christian Svenning, Wilfried Thuiller, Patrick Weigelt, Thomas Wohlgemuth, Qiang Yang & Mark Van Kleunen
Aims: The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains largely misunderstood. We therefore ask whether naturalized species will respond to climate and land-use change differently than those species not yet naturalized anywhere in the world. Location: Global Methods: We investigated future...

Rachel Stubbington, Romain Sarremejane, Alex Laini, Núria Cid, Zoltán Csabai, Judy England, Antoni Munné, Tom Aspin, Núria Bonada, Daniel Bruno-Collados, Sophie Cauvy-Fraunie, Richard Chadd, Claudia Dienstl, Pau Fortuño, Wolfram Graf, Cayetano Gutiérrez-Cánovas, Andy House, Ioannis Karaouzas, Eleana Kazila, Andrés Millán, Maria Morais, Petr Pařil, Alex Pickwell, Marek Polášek, David Sánchez-Fernández … & Thibault Datry
1. Rivers are dynamic ecosystems in which both human impacts and climate-driven drying events are increasingly common. These anthropogenic and natural stressors interact to influence the biodiversity and functioning of river ecosystems. Disentangling ecological responses to these interacting stressors is necessary to guide management actions that support ecosystems adapting to global change. 2. We analysed the independent and interactive effects of human impacts and natural drying on aquatic invertebrate communities—a key biotic group used to...

Data from: New drivers of the evolution of mimetic accuracy in Batesian mimics: body size, habitat stratification and geographic zone affect accuracy of myrmecomorphic spiders

Stano Pekar
Aim: The evolution and maintenance of accurate Batesian mimicry has been explained by several hypotheses built upon relaxed selection. Such selection can be influenced by ecological factors, such as habitat type or geographic distribution, which have not been considered. I investigated whether the mimetic accuracy is influenced by habitat stratification where mimics occur (ground, low vegetation, bush, tree), their body size, and geographic distribution (temperate, subtropical, tropical). Location: Worldwide Taxon: Araneae Methods: I gathered data...

Denys Vynokurov, Tatiana Lysenko, Zoya Dutova, Dmitriy Shylnikov, Galina Doroshina, Irina Urbanavichene, Gennadii Urbanavichus & Nelly Tsepkova
The North Caucasus is still one of the least studied regions in Europe regarding syntaxonomy. We investigated dry grasslands in the central part of the North Caucasus, namely in the Stavropol Kray region of Russia. We sampled 47 vegetation plots (relevés) of 10 m2 size (3.16 × 3.16 m) at elevations from 470 to 1150 m a.s.l. To determine the scale-dependent species richness patterns, we recorded five nested-plot series of 0.0001 to 100 m² in...

Carpinus orientalis forests in Georgian Colchis: First insights

Pavel Novák, Vladimir Stupar & Veronika Kalníková
Colchis (Caucasus Ecoregion, Euxinian Province) is a region with unique Tertiary relict biota and high species and vegetation diversity. However, its vegetation has been only little studied by Braun- Blanquet methods so far. Based on original field data (20 phytosociological relevés), we describe a novel vegetation type of calciphilous and thermophilous Carpinus orientalis forests in western Geor- gia (Campanulo alliariifoliae-Carpinetum orientalis ass. nova). This species-rich community inhabits sunny limestone slopes and is developed under a...

Although spatial and temporal variation are both important components structuring microbial communities, the exact quantification of temporal turnover rates of fungi and bacteria has not been performed to date. In this study, we utilized repeated resampling of bacterial and fungal communities at specific locations across multiple years to describe their patterns and rates of temporal turnover. Our results show that microbial communities undergo temporal change at a rate of 0.010-0.025 per year (in units of...

The effect of niche filtering on plant species abundance in temperate grassland communities

Josep Padullés Cubino, Irena Axmanová, Zdeňka Lososová, Martin Večeřa, Ariel Bergamini, Helge Bruelheide, Jürgen Dengler, Ute Jandt, Florian Jansen, Ricarda Pätsch & Milan Chytrý
1. Niche filtering predicts that abundant species in communities have similar traits that are suitable for the environment. However, niche filtering can operate on distinct axes of trait variation in response to different ecological conditions. Here, we use a trait-based approach to infer niche filtering processes and (1) test if abundant and rare species in grassland communities are differently positioned along distinct axes of trait variation, (2) determine if these trait variation axes, as well...

Aim: Alpine habitats support unique biodiversity confined to high-elevation areas in the current interglacial. Plant diversity in these habitats responds to area, environment, connectivity and isolation, yet these factors have been rarely evaluated in concert. Here we investigate major determinants of regional species pools in alpine grasslands, and the responses of their constituent species groups. Location: European mountains below 50ºN. Time Period: Between 1928 and 2019. Major Taxa Studied: Vascular plants. Methods: We compiled species...

What defines insularity for plants in edaphic islands?

Francisco Emmanuel Méndez Castro, Luisa Conti, Milan Chytrý, Borja Jimenez-Alfaro, Michal Hajek, Michal Horsák, David Zeleny, Marco Malavasi & Gianluigi Ottaviani
The Theory of Island Biogeography postulates that size and isolation are key drivers of biodiversity on islands. This theory has been applied not only to true (e.g. oceanic) islands but also to terrestrial island-like systems (e.g. edaphic islands). Recently, a debate has opened as to whether terrestrial island-like systems function like true islands. However, identifying the effect of insularity in terrestrial systems is conceptually and methodologically challenging because recognizing species source(s) and measuring isolation is...

The formation of inclusion complexes between cucurbit[7]uril (CB[7]) and ferrocene and its derivatives has been investigated. The X-ray crystal structure of the 1:1 inclusion complex between ferrocene and CB[7] revealed that the guest molecule resides in the host cavity with two different orientations. Inclusion of a set of five water-soluble ferrocene derivatives in CB[7] was investigated by 1H NMR spectroscopy and calorimetric and voltammetric techniques. Our data indicate that all neutral and cationic guests form...
