1. Assemblages of insect herbivores are structured by plant traits such as nutrient content, secondary metabolites, physical traits, and phenology. Many of these traits are phylogenetically conserved, implying a decrease in trait similarity with increasing phylogenetic distance of the host plant taxa. Thus, a metric of phylogenetic distances and relationships can be considered a proxy for phylogenetically conserved plant traits and used to predict variation in herbivorous insect assemblages among co-occurring plant species. 2. Using...

Data from: Competition among native and invasive Phragmites australis populations: an experimental test of the effects of invasion status, genome size, and ploidy level.

Among the traits whose relevance for plant invasions has recently been suggested are genome size (the amount of nuclear DNA) and ploidy level. So far, research on the role of genome size in invasiveness has been mostly based on indirect evidence by comparing species with different genome sizes, but how karyological traits influence competition at the intraspecific level remains unknown. We addressed these questions in a common‐garden experiment evaluating the outcome of direct intraspecific competition...

Data from: Experimental assessment of biotic and abiotic filters driving community composition

Eva Švamberková & Jan Leps
Species occurrence in a site can be limited by both the abiotic environment and biotic interactions. These two factors operate in concert, but their relative importance is often unclear. By experimentally introducing seeds or plants into competition-free gaps or into the intact vegetation, we can disentangle the biotic and abiotic effects on plant establishment. We established a seed sowing/transplant experiment in three different meadows. Species were introduced, as seeds and pre-grown transplants, into competition-free gaps...

Parasite turnover zone at secondary contact: a new pattern in host-parasite population genetics

Jana Martinu, Jan Stefka, Anbu Poosakkannu & Vaclav Hypsa
We introduce a new pattern of population genetic structure in a host-parasite system that can arise after secondary contact of previously isolated populations. Due to different generation time and therefore different tempo of molecular evolution the host and parasite populations reach different degrees of genetic differentiation during their separation (e.g. in refugia). Consequently, during the secondary contact the host populations are able to re-establish a single panmictic population across the area of contact, while the...

Effects of past and present-day landscape structure on forest soil microorganisms

Mélanie Roy, Sophie Mennicken, Floriane Kondratow, Florian Buralli, Sophie Manzi, Emilie Andrieu & Antoine Brin
Principles of landscape ecology have been built on birds and plant species distribution, but the number of clues is now growing on below-ground organisms, whose dispersal may also be affected by above-ground landscape structure. For communities of microorganisms, the question remains if and how they answer to landscape structure, with or without time lag, and if some groups of microorganisms may react more than others. Here, we investigated if fungi or bacteria diversity is driven...

Data for: Foraging speed and precision of arbuscular mycorrhizal fungi under field conditions: An experimental approach

Petr Šmilauer, Marie Šmilauerová, Milan Kotilínek & Jiří Košnar
To better understand the ecology of arbuscular mycorrhizal (AM) symbiosis, we need to measure functional traits of individual fungal virtual taxa under field conditions. The efficiency of AM fungi in locating nutrient-rich patches in soil space is one of their central traits in this symbiotic relationship. We used plots of a long-term field experiment in grassland with manipulated functional group composition of host plant community to establish ingrowth patches with substrate free of roots and...

Data from: Evolution of multiple sex-chromosomes associated with dynamic genome reshuffling in Leptidea wood-white butterflies

Atsuo Yoshido, Jindra Šíchová, Kristýna Pospíšilová, Petr Nguyen, Anna Voleníková, Jan Šafář, Jan Provazník, Roger Vila & František Marec
Sex chromosome systems tend to be highly conserved and knowledge about their evolution typically comes from macroevolutionary inferences. Rapidly evolving complex sex chromosome systems represent a rare opportunity to study the mechanisms of sex chromosome evolution at unprecedented resolution. Three cryptic species of wood white butterflies – Leptidea juvernica, L. sinapis, and L. reali – have each a unique set of multiple sex chromosomes with 3–4 W and 3–4 Z chromosomes. Using a transcriptome-based microarray...

Data from: Temperature does not influence functional response of amphipods consuming different trematode prey

Ana Born-Torrijos, Rachel A. Paterson, Gabrielle S. Van Beest, Jessica Schwelm, Tereza Vyhlídalová, Eirik H. Henriksen, Rune Knudsen, Roar Kristoffersen, Per-Arne Amundsen & Miroslava Soldánová
Direct consumption on free-living cercariae stages of trematodes by non-host organisms interferes with trematode transmission and leads to reduced infections in the next suitable hosts. Consumer functional responses provide a useful tool to examine relationships between consumption rates and ecologically relevant prey densities, whilst also accounting for abiotic factors that likely influence consumption rates. We investigated how temperature influences the consumer functional response of the amphipod Gammarus lacustris towards the cercariae of three freshwater trematodes...

Data from: Butterfly and moth communities differ in their response to habitat structure in rainforests of Mount Cameroon

Sylvain Delabye, Vincent Maicher, Szabolcs Sáfián, Jiří Doležal, Jan Altman, Štěpán Janeček, Ishmeal Kobe, Mercy Murkwe, Pavel Šebek & Robert Tropek
Mechanisms structuring tropical communities are still under-studied, especially in Afrotropical rainforests. Although insect herbivores are considered to depend on plant diversity, we hypothesized that vegetation structure, together with other microhabitat characteristics, can be more important for some insects. Here, we compared habitat associations of fruit-feeding butterflies and moths, two ecologically different groups of Lepidoptera, in three rainforest localities in foothills of Mount Cameroon, West/Central Africa. Based on a comprehensive dataset of 16,040 specimens of 398...
