Data from: Functional basis of the sexual dimorphism in the auditory fovea of the duetting bushcricket Ancylecha fenestrataJan Scherberich, Jennifer Hummel, Stefan Schöneich & Manuela Nowotny
From mammals to insects, acoustic communication is in many species crucial for successful reproduction. In the duetting bushcricket Ancylecha fenestrata, the mutual acoustic communication between males and females is asymmetrical. We investigated how those signalling disparities are reflected by sexual dimorphism of their ears. Both sexes have tympanic ears in their forelegs, but male ears possess a significantly longer crista acustica containing 35% more scolopidia. With more sensory cells to cover a similar hearing range,...
Data from: Trophic and non-trophic interactions influence the mechanisms underlying biodiversity–ecosystem functioning relationships under different abiotic conditionsNathaly R. Guerrero-Ramírez & Nico Eisenhauer
Plant diversity effects on ecosystem functioning usually have been studied from a plant perspective. However, the mechanisms underlying biodiversity–ecosystem functioning relationships may also depend on positive or negative interactions between plants and other biotic and abiotic factors, which remain poorly understood. Here we assessed whether plant–herbivore and/or plant–detritivore interactions modify the biodiversity–ecosystem functioning relationship and the mechanisms underlying biodiversity effects, including complementarity and selection effects, biomass allocation, vertical distribution of roots, and plant survival using...
Data from: Characterization of unexplored deadwood mycobiome in highly diverse subtropical forests using culture-independent molecular techniqueWitoon Purahong, Katherina A. Pietsch, Guillaume Lentendu, Ricardo Schöps, Helge Bruelheide, Christian Wirth, François Buscot & Tesfaye Wubet
The deadwood mycobiome, also known as wood-inhabiting fungi (WIF), are among the key players in wood decomposition, having a large impact on nutrient cycling in forest soils. However, our knowledge of WIF richness and distribution patterns in different forest biomes is limited. Here, we used pyrotag sequencing of the fungal internal transcribed spacer (ITS2) region to characterize the deadwood mycobiome of two tree species with greatly different wood characteristics (Schima superba and Pinus massoniana) in...
Data from: Belowground complementarity effects in a grassland biodiversity experiment are related to deep-rooting speciesNatalie J. Oram, Janneke M. Ravenek, Kathryn E. Barry, Alexandra Weigelt, Hongmei Chen, Arthur Gessler, Annette Gockele, Hans De Kroon, Jan Willem Van Der Paauw, Michael Scherer-Lorenzen, Annemiek Smit-Tiekstra, Jasper Van Ruijven & Liesje Mommer
1. Belowground resource partitioning is often proposed as the underlying mechanism for the positive relationship between plant species richness and productivity. For example, if species have different root distributions, a mixture of plant species may be able to use the available resources more completely than the individual species in a monoculture. However, there is little experimental evidence for differentiation in vertical root distributions among species and its contribution to biodiversity effects. 2. We determined species-specific...
1. Biological invasions pose a serious threat to biodiversity and ecosystem functioning across ecosystems. Invasions by ecosystem engineers, in particular, have been shown to have dramatic effects in recipient ecosystems. For instance, invasion by earthworms, a belowground invertebrate ecosystem engineer, in previously earthworm-free ecosystems dramatically alters the physico-chemical characteristics of the soil. Studies have shown that such alterations in the soil can have far-reaching impacts on soil organisms, which form a major portion of terrestrial...
Data from: Nitrogen deposition cancels out exotic earthworm effects on plant-feeding nematode communitiesYuanhu Shao, Weixin Zhang, Nico Eisenhauer, Tao Liu, Yanmei Xiong, Chenfei Liang & Shenglei Fu
The activity and spread of exotic earthworms often are spatially correlated with N deposition because both arise from human activities. Exotic earthworms, in turn, can also greatly affect soil abiotic and biotic properties, as well as related ecological processes. Previous studies showed, for example, that earthworms can counteract the detrimental effects of plant-feeding nematodes on plant growth. However, potential interactive effects of N deposition and exotic earthworms on ecosystems are poorly understood. We explored the...
Negative relationships between species richness and elevation are common and attributed to changes in single environmental properties associated to elevation, such as temperature and habitat area. However, research has lacked taxonomic breadth and comprehensive elevation studies that consider multiple groups from different trophic levels are rare. We thus analysed 24 groups of plants, arthropods, and microorganisms grouped into six trophic guilds (predators, detritivores, herbivores, plants, bacteria and fungi) along a relatively short elevational gradient (~600...
Data from: Warming magnifies predation and reduces prey coexistence in a model litter arthropod systemMadhav P. Thakur, Tom Kunne, John N. Griffin & Nico Eisenhauer
Climate warming can destabilize interactions between competitors as smaller organisms gain advantages in warmer environments. Whether and how warming-induced effects on competitive interactions are modified by predation remains unknown. We hypothesized that predation will offset the competitive advantage of smaller prey species in warmer environments because of their greater vulnerability to predation. To test this, we assembled a litter arthropod community with two Collembola species (Folsomia candida and Proisotoma minuta) of different body sizes across...
1. Olfaction is a central aspect of mammalian communication, providing information about individual attributes such as identity, sex, group membership or genetic quality. Yet, the chemical underpinnings of olfactory cues remain little understood, one of the reasons being the difficulty in obtaining high quality samples for chemical analysis. 2. In the present study we adjusted and evaluated the use of thermal desorption (TD) tubes, commonly used in plant metabolomic and environmental studies, for non-invasive sampling...
Data from: Testing the applicability of a benthic foraminiferal-based transfer function for the reconstruction of paleowater depth changes in Rhodes (Greece) during the early PleistoceneYvonne Milker, Manuel F.G. Weinkauf, Jürgen Titschack, Andre Freiwald, Stefan Krüger, Frans J. Jorissen, Gerhard Schmiedl & Manuel F. G. Weinkauf
We present paleo-water depth reconstructions for the Pefka E section deposited on the island of Rhodes (Greece) during the early Pleistocene. For these reconstructions, a transfer function (TF) using modern benthic foraminifera surface samples from the Adriatic and Western Mediterranean Seas has been developed. The TF model gives an overall predictive accuracy of ~50 m over a water depth range of ~1200 m. Two separate TF models for shallower and deeper water depth ranges indicate...
Data from: Soil drainage facilitates earthworm invasion and subsequent carbon loss from peatland soilXinwei Wu, Rui Cao, Xue Wei, Xinqiang Xi, Peili Shi, Nico Eisenhauer & Shucun Sun
1. Human activities have been a significant driver of environmental changes with tremendous consequences for carbon dynamics. Peatlands are critical ecosystems because they store ~30% of the global soil organic carbon pool and are particularly vulnerable to anthropogenic changes. The Zoige peatland on the eastern Tibet Plateau, as the largest alpine peatland in the world, accounts for 1‰ of global peat soil organic carbon storage. However, this peatland has experienced dramatic climate change including increased...
Data from: Resource stoichiometry and availability modulate species richness and biomass of tropical litter macro-invertebratesMalte Jochum, Andrew D. Barnes, Patrick Weigelt, David Ott, Katja Rembold, Achmad Farajallah & Ulrich Brose
1. The high biodiversity and biomass of soil communities is crucial for litter decomposition in terrestrial ecosystems such as tropical forests. However, the leaf litter that these communities consume is of particularly poor quality as indicated by elemental stoichiometry. The impact of resource quantity, quality, and other habitat parameters on species richness and biomass of consumer communities is often studied in isolation, although much can be learned from simultaneously studying both community characteristics. 2. Using...
Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forestsPeter Schall, Martin M. Gossner, Steffi Heinrichs, Markus Fischer, Steffen Boch, Daniel Prati, Kirsten Jung, Vanessa Baumgartner, Stefan Blaser, Stefan Böhm, Francois Buscot, Rolf Daniel, Kezia Goldmann, Kirstin Kaiser, Tiemo Kahl, Markus Lange, Jörg Müller, Jörg Overmann, Swen C. Renner, Ernst-Detlef Schulze, Johannes Sikorski, Marco Tschapka, Manfred Türke, Wolfgang W. Weisser, Bernd Wemheuer … & Kristin Kaiser
For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged management over more traditional coarse-grained even-aged management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous...
Data from: Land-use type and intensity differentially filter traits in above- and belowground arthropod communitiesKlaus Birkhofer, Martin M. Gossner, Tim Diekötter, Claudia Drees, Olga Ferlian, Mark Maraun, Stefan Scheu, Wolfgang W. Weisser, Volkmar Wolters, Susanne Wurst, Andrey S. Zaitsev & Henrik G. Smith
1. Along with the global decline of species richness goes a loss of ecological traits. Associated biotic homogenization of animal communities and narrowing of trait diversity threaten ecosystem functioning and human well-being. High management intensity is regarded as an important ecological filter, eliminating species that lack suitable adaptations. Belowground arthropods are assumed to be less sensitive to such effects than aboveground arthropods. 2. Here, we compared the impact of management intensity between (grassland vs. forest)...
