Jörg Müller, Roland Brandl, Martin Brändle, Bernhard Förster, Bruno Cancian De Araujo, Martin M. Gossner, Alexander Ladas, Martin Wagner, Mark Maraun, Peter Schall, Stefan Schmidt, Marco Heurich, Simon Thorn & Sebastian Seibold
Despite considerable progress in the ability to measure the complex 3-D structure of forests with the improvement of remote-sensing techniques, our mechanistic understanding of how biodiversity is linked to canopy structure is still limited. Here we tested whether the increase in arthropod abundance and richness in beech forest canopies with increasing canopy complexity supports the more-individuals hypothesis or the habitat-heterogeneity hypothesis. We used fogging to collect arthropod samples from 80 standardized plots from canopies of...

Data from: Habitat diversity and connectivity govern the conservation value of restored aquatic floodplain habitats

Joachim Pander, Melanie Mueller & Juergen Geist
Floodplains have been strongly altered by human activities such as channelization and other river regulations. Globally, there is a growing interest in their restoration because of an increasing understanding of the ecological importance of these habitats for feeding, spawning, nursery or overwintering of aquatic species. In this study, a large floodplain restoration project of the upper Danube River was used to investigate colonization and succession patterns of fish, macroinvertebrates, macrophytes and periphyton in relation to...

Data from: Resource availability determines the importance of niche-based vs. stochastic community assembly in grasslands

Timo Conradi, Vicky M. Temperton & Johannes Kollmann
Niche-based selection and stochastic processes can operate simultaneously to generate spatial and temporal variation in species composition. Yet, the conditions under which ecological dynamics are dominated by niche-based vs. stochastic processes are poorly understood. Using a field experiment in early-successional temperate grassland and null models of beta diversity, this study investigates the effects of soil nutrient supply on the relative importance of niche-based selection vs. stochastic dynamics for variation in species composition among sites. Nutrient...

Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests

Peter 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 communities

Klaus 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)...

Michael Heym, Ricardo Ruíz-Peinado, Miren Del Río, Kamil Bielak, David I. Forrester, Gerald Dirnberger, Ignacio Barbeito, Gediminas Brazaitis, Indrė Ruškytė, Lluís Coll, Marek Fabrika, Lars Drössler, Magnus Löf, Hubert Sterba, Václav Hurt, Viktor Kurylak, Fabio Lombardi, Dejan Stojanović, Jan Den Ouden, Renzo Motta, Maciej Pach, Jerzy Skrzyszewski, Quentin Ponette, Géraud De Streel, Vit Sramek … & Hans Pretzsch
This data set provides unique empirical data from triplets of Scots pine (Pinus sylvestris L.) and European beech (Fagus sylvatica L.) across Europe. Dendrometric variables are provided for 32 triplets, 96 plots, 7555 trees and 4695 core samples. These data contribute to our understanding of mixed stand dynamics.

Data from: Invasion strategies in round goby (Neogobius melanostomus): is bigger really better?

Joerg Brandner, Alexander F. Cerwenka, Ulrich K. Schliewen & Juergen Geist
Few studies have systematically investigated mid- or long-term temporal changes of biological characteristics in invasive alien species considering the different phases of an invasion. We studied the invasion performance of one of the most invasive species worldwide, the round goby Neogobius melanostomus, from total absence over first occurrence until establishment from 2010 to 2015 in the upper Danube River. After an upstream movement of the invasion front of about 30 river km within four years,...

Data from: A systematic approach to evaluate the influence of environmental conditions on eDNA detection success in aquatic ecosystems

Bernhard C. Stoeckle, Sebastian Beggel, Alexander Cerwenka, Elena Motivans, Ralph Kuehn & Juergen Geist
The use of environmental DNA (eDNA) to determine the presence and distribution of aquatic organisms has become an important tool to monitor and investigate freshwater communities. The successful application of this method in the field, however, is dependent on the effectiveness of positive DNA verification, which is influenced by site-specific environmental parameters. Factors affecting lower eDNA concentrations in aquatic ecosystems include flow conditions, and the presence of substances that possess DNA-binding properties or inhibitory effects....

Data from: Ecosystem services and disservices provided by small rodents in arable fields: effects of local and landscape management

Christina Fischer, Christoph Gayer, Kornélia Kurucz, Friederike Riesch, Teja Tscharntke & Péter Batáry
1. In agriculture, both valuable ecosystem services and unwanted ecosystem disservices can be produced by the same organism group. For example, small rodents can provide biological control through weed seed consumption but may also act as pests, causing crop damage. 2. We studied the hypothesised causal relationships between ecosystem services (removal of weed seeds) and disservices (removal of wheat and crop damage) derived by small rodents (voles and mice) at multiple spatial scales. At the...

Data from: Trophic level, successional age and trait matching determine specialization of deadwood-based interaction networks of saproxylic beetles

Beate Wende, Martin M. Gossner, Ingo Grass, Tobias Arnstadt, Martin Hofrichter, Andreas Floren, Karl Eduard Linsenmair, Wolfgang W. Weisser & Ingolf Steffan-Dewenter
The specialization of ecological networks provides important insights into possible consequences of biodiversity loss for ecosystem functioning. However, mostly mutualistic and antagonistic interactions of living organisms have been studied, whereas detritivore networks and their successional changes are largely unexplored. We studied the interactions of saproxylic (deadwood-dependent) beetles with their dead host trees. In a large-scale experiment, 764 logs of 13 tree species were exposed to analyse network structure of three trophic groups of saproxylic beetles...

Data from: Incorporating ecological functions in conservation decision making

Emilia Decker, Simon Linke, Virgilio Hermoso & Juergen Geist
Systematic conservation planning has become a standard approach globally, but prioritization of conservation efforts hardly considers species traits in decision-making. This can be important for species persistence and thus adequacy of the conservation plan. Here, we developed and validated a novel approach of incorporating trophic information into a systematic conservation planning framework. We demonstrate the benefits of this approach by using fish data from Europe´s second largest river, the Danube. Our results show that adding...

Data from: Platelet GPIIb supports initial pulmonary retention but inhibits subsequent proliferation of melanoma cells during hematogenic metastasis

Christian Schulz, Katrin Echtler, Ildiko Konrad, Michael Lorenz, Simon Schneider, Sebastian Hofmaier, Florian Plenagl, Konstantin Stark, Thomas Czermak, Anca Tirniceriu, Martin Eichhorn, Axel Walch, Georg Enders & Steffen Massberg
Platelets modulate the process of cancer metastasis. However, current knowledge on the direct interaction of platelets and tumor cells is mostly based on findings obtained in vitro. We addressed the role of the platelet fibrinogen receptor glycoprotein IIb (integrin αIIb) for experimental melanoma metastasis in vivo. Highly metastatic B16-D5 melanoma cells were injected intravenously into GPIIb-deficient (GPIIb-/-) or wildtype (WT) mice. Acute accumulation of tumor cells in the pulmonary vasculature was assessed in real-time by...

Data from: Coexistence through mutualist-dependent reversal of competitive hierarchies

Mohsen Mehrparvar, Sharon E. Zytynska, Adalbert Balog & Wolfgang W. Weisser
Mechanisms that allow for the coexistence of two competing species that share a trophic level can be broadly divided into those that prevent competitive exclusion of one species within a local area, and those that allow for coexistence only at a regional level. While, the presence of aphid-tending ants can change the distribution of aphids among host-plants, the role of mutualistic ants has not been fully explored to understand coexistence of multiple aphid species in...
