Data from: Selective logging intensity in an East African rain forest predicts reductions in ant diversity

Samuel R. P-J. Ross, Francisco Hita Garcia, Georg Fischer, Marcell K. Peters & Samuel R. P.-J. Ross
As natural forest ecosystems increasingly face pressure from deforestation, it is ever more important to understand the impacts of habitat fragmentation and degradation on biodiversity. Most studies of anthropogenic change in the tropics come from Southeast Asia and South America, and impacts of habitat modification are often taxon-specific. Here we empirically assessed the impact of habitat fragmentation and recent (within 25 years) and historic (>25 years ago) selective logging on the diversity of ants in...

O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: Independent effects of host and environment on the diversity of wood-inhabiting fungi

Franz-Sebastian Krah, Sebastian Seibold, Roland Brandl, Petr Baldrian, Jörg Müller & Claus Bässler
1. Dead wood is a habitat for numerous fungal species, many of which are important agents of decomposition. Previous studies suggested that wood-inhabiting fungal communities are affected by climate, availability of dead wood in the surrounding landscape and characteristics of the colonized dead-wood object (e.g. host tree species). These findings indicate that different filters structure fungal communities at different scales, but how these factors individually drive fungal fruiting diversity on dead-wood objects is unknown. 2....

Data from: Landscape-level crop diversity benefits biological pest control

Sarah Redlich, Emily A. Martin & Ingolf Steffan-Dewenter
1.Landscape-level crop diversification is a promising tool for ecological intensification, whereby biodiversity and ecosystem services are enhanced, and pesticide applications reduced. Yet evidence for the effects of crop diversity at multiple scales and in different landscape contexts is lacking. Here, we investigate the potential benefits and context-dependencies of multiscale crop diversity on natural enemies and overall biological control in winter wheat. Simultaneously, we examine the mediating effects of bird predation on aphid regulation in this...

Data from: Agri-environmental schemes promote ground-dwelling predators in adjacent oilseed rape fields: diversity, species traits and distance-decay functions

Fabian A. Boetzl, Elena Krimmer, Jochen Krauss & Ingolf Steffan-Dewenter
1. Rising demands for agricultural products and high environmental costs of intensive agriculture reinforce the need for ecological replacements in agricultural management. In Europe, agri-environmental schemes (AES) are implemented to enhance species richness and provision of ecosystem services, but the effectiveness of different AES types and the spatial extent of possible beneficial effects are little understood. In this study we assessed the effects of different AES types on diversity, species traits and distance-decay functions of...

Data from: Minimal effects on genetic structuring of a fungus-dwelling saproxylic beetle after recolonization of a restored forest

Sharon E. Zytynska, Inken Doerfler, Martin M. Gossner, Sarah Sturm, Wolfgang W. Weisser & Jörg Müller
1. Habitat restoration aims to improve local habitat conditions for threatened species. While such restorations are widespread, rigorous evaluations of their success are rare. This is especially true of those considering species dynamics. Increasingly, deadwood is a target for forest restoration as many species directly and indirectly depend on this resource. 2. In a broadleaf forest in southern Germany, we explored the effect of landscape-wide deadwood restoration on the population genetic structure of the specialist...

Data from: Biodiversity along temperate forest succession

Torben Hilmers, Nicolas Friess, Claus Bässler, Marco Heurich, Roland Brandl, Hans Pretzsch, Rupert Seidl & Jörg Müller
1. The successional dynamics of forests – from canopy openings to regeneration, maturation and decay – influences the amount and heterogeneity of resources available for forest-dwelling organisms. Conservation has largely focused only on selected stages of forest succession (e.g. late-seral stages). However, to develop comprehensive conservation strategies and to understand the impact of forest management on biodiversity, a quantitative understanding of how different trophic groups vary over the course of succession is needed. 2. We...

Data from: Low levels of hybridization in two species of African driver ants

Ian A. Butler, Marcell K. Peters, Daniel J.C. Kronauer & D. J. C. Kronauer
Hybridization in ants can have consequences different from those observed in most other species, with many of the potential deleterious effects being mitigated due to haplodiploidy and eusociality. In some species where colonies are either headed by multiple queens or single queens that mate with many males, hybridization is associated with genetic caste determination, where hybrids develop into workers and purebred individuals develop into queens. A previous study suggested that hybridization occurs between two Dorylus...

Data from: Long-term experimental hybridisation results in a heterologous transition and the evolution of a new sex chromosome in swordtail fish

Paolo Franchini, Julia C. Jones, Peiwen Xiong, Susanne Kneitz, Zachariah Gompert, Wesley C. Warren, Ronald B. Walter, Axel Meyer & Manfred Schartl
The remarkable diversity of sex determination mechanisms known in fish may be fuelled by exceptionally high rates of sex chromosome turnovers or transitions. However, the evolutionary causes and genomic mechanisms underlying this variation and instability are yet to be understood. Here we report on an over 30-year evolutionary experiment in which we tested the genomic consequences of hybridisation and selection between two Xiphophorus fish species with different sex chromosome systems. We find that introgression and...

Data from: Natural variation in stomata size contributes to the local adaptation of water-use efficiency in Arabidopsis thaliana

Hannes Dittberner, Arthur Korte, Tabea Mettler-Altmann, Andreas P.M. Weber, Grey Monroe & Juliette De Meaux
Stomata control gas exchanges between the plant and the atmosphere. How natural variation in stomata size and density contributes to resolve trade‐offs between carbon uptake and water‐loss in response to local climatic variation is not yet understood. We developed an automated confocal microscopy approach to characterize natural genetic variation in stomatal patterning in 330 fully‐sequenced Arabidopsis thaliana accessions collected throughout the European range of the species. We compared this to variation in water‐use efficiency, measured...

Data from: In-situ recording of ionic currents in projection neurons and Kenyon cells in the olfactory pathway of the honeybee

Jan Kropf, Wolfgang Roessler & Wolfgang Rössler
The honeybee olfactory pathway comprises an intriguing pattern of convergence and divergence: ~60.000 olfactory sensory neurons (OSN) convey olfactory information on ~900 projection neurons (PN) in the antennal lobe (AL). To transmit this information reliably, PNs employ relatively high spiking frequencies with complex patterns. PNs project via a dual olfactory pathway to the mushroom bodies (MB). This pathway comprises the medial (m-ALT) and the lateral antennal lobe tract (l-ALT). PNs from both tracts transmit information...

Data from: Lifelong foraging and individual specialisation are influenced by temporal changes of resource availability

Viktor Szigeti, Ádám Kőrösi, Andrea Harnos & János Kis
Resource availability largely determines the distribution and behaviour of organisms. In plant‐pollinator communities, availability of floral resources may change so rapidly that pollinator individuals can benefit from switching between multiple resources, i.e. different flowering plant species. Insect pollinator individuals of a given generation often occur in different time windows during the reproductive season. This temporal variation in individual occurrences, together with the rapidly changing resource availability, may lead individuals of the same population to encounter...
