Data from: Relaxed predation results in reduced phenotypic integration in a suite of dragonflies

Dirk Johannes Mikolajewski, Linda Rüsen, Rüdiger Mauersberger, Frank Johansson & Jens Rolff
While changes in magnitude of single traits responding to selective agents have been studied intensively, little is known about selection shaping networks of traits and their patterns of co-variation. However, this is central for our understanding of phenotypic evolution since traits are embedded in a multivariate environment with selection affecting a multitude of traits simultaneously rather than individually. Here, we investigate inter- and intraspecific patterns of trait integration (trait correlations) in the larval abdomen of...

Data from: Beyond predation: the zoophytophagous predator Macrolophus pygmaeus induces tomato resistance against spider mites

Maria L. Pappas, Anke Steppuhn, Daniel Geuss, Nikoleta Topalidou, Aliki Zografou, Maurice W. Sabelis & George D. Broufas
Many predatory insects that prey on herbivores also feed on the plant, but it is unknown whether plants affect the performance of herbivores by responding to this phytophagy with defence induction. We investigate whether the prior presence of the omnivorous predator Macrolophus pygmaeus (Rambur) on tomato plants affects plant resistance against two different herbivore species. Besides plant-mediated effects of M. pygmaeus on herbivore performance, we examined whether a plant defence trait that is known to...

Data from: The evolution of bat nucleic acid sensing Toll-like receptors

Marina Escalera-Zamudio, Lisandra M. Zepeda-Mendoza, Elizabeth Loza-Rubio, Edith Rojas-Anaya, Maria L. Méndez-Ojeda, Carlos F. Arias & Alex D. Greenwood
We characterized the nucleic acid sensing Toll-like receptors (TLR) of a New World bat species, the common vampire bat (Desmodus rotundus), and through a comparative molecular evolutionary approach searched for general adaptation patterns among the nucleic acid sensing TLRs of eight different bats species belonging to three families (Pteropodidae, Vespertilionidae and Phyllostomidae). We found that the bat TLRs are evolving slowly and mostly under purifying selection and that the divergence pattern of such receptors is...

Data from: Do arbuscular mycorrhizal fungi stabilize litter-derived carbon in soil?

Erik Verbruggen, Jan Jansa, Edith C. Hammer & Matthias C. Rillig
1. Fine roots and mycorrhiza often represent the largest input of carbon (C) into soils, and are therefore of primary relevance to the soil C balance. Arbuscular mycorrhizal (AM) fungi have previously been found to increase litter decomposition which may lead to reduced soil C stocks, but these studies have focused on immediate decomposition of relatively high amounts of high-quality litter and may therefore not hold in many ecological settings over longer terms. 2. Here...

Data from: Extreme environments facilitate hybrid superiority - the story of a successful Daphnia galeata × longispina hybrid clone

Johanna Griebel, Sabine Gießler, Monika Poxleitner, Amanda Navas Faria, Mingbo Yin & Justyna Wolinska
Hybridization within the animal kingdom has long been underestimated. Hybrids have often been considered less fit than their parental species. In the present study, we observed that the Daphnia community of a small lake was dominated by a single D. galeata × D. longispina hybrid clone, during two consecutive years. Notably, in artificial community set-ups consisting of several clones representing parental species and other hybrids, this hybrid clone took over within about ten generations. Neither...

Data from: Evolution and biogeography of the endemic Roucela complex (Campanulaceae: Campanula) in the eastern Mediterranean

Andrew A. Crowl, Clayton J. Visger, Guilhem Mansion, Ralf Hand, Hsin-Hui Wu, Georgia Kamari, Dimitrios Phitos & Nico Cellinese
At the intersection of geological activity, climatic fluctuations, and human pressure, the Mediterranean Basin – a hotspot of biodiversity – provides an ideal setting for studying endemism, evolution, and biogeography. Here, we focus on the Roucela complex (Campanula subgenus Roucela), a group of 13 bellflower species found primarily in the eastern Mediterranean Basin. Plastid and low-copy nuclear markers were employed to reconstruct evolutionary relationships and estimate divergence times within the Roucela complex using both concatenation...

Data from: Resources alter the structure and increase stochasticity in bromeliad microfauna communities

Jana S. Petermann, Pavel Kratina, Nicolas A. C. Marino, A. Andrew M. MacDonald, Diane S. Srivastava & Nicholas A. C. Marino
Although stochastic and deterministic processes have been found to jointly shape structure of natural communities, the relative importance of both forces may vary across different environmental conditions and across levels of biological organization. We tested the effects of abiotic environmental conditions, altered trophic interactions and dispersal limitation on the structure of aquatic microfauna communities in Costa Rican tank bromeliads. Our approach combined natural gradients in environmental conditions with experimental manipulations of bottom-up interactions (resources), top-down...

Data from: \"Transcriptomic resources for the critically endangered stellate sturgeon Acipenser stellatus\" in Genomic Resources Notes accepted 1 April 2015 – 31 May 2015

Michele Vidotto, Alessandro Grapputo, Elisa Boscari, Lorenzo Zane & Leonardo Congiu
This article documents the public availability of transcriptomic resources of the non-model and critically endangered starlet sturgeon Acipenser stellatus.

Data from: Bypass of genetic constraints during mutator evolution to antibiotic resistance

Alejandro Couce, Alexandro Rodríguez-Rojas, Jesús Blázquez, A. Rodriguez-Rojas & J. Blazquez
Genetic constraints can block many mutational pathways to optimal genotypes in real fitness landscapes, yet the extent to which this can limit evolution remains to be determined. Interestingly, mutator bacteria elevate only specific types of mutations, and therefore could be very sensitive to genetic constraints. Testing this possibility is not only clinically relevant, but can also inform about the general impact of genetic constraints in adaptation. Here, we evolved 576 populations of two mutator and...
