The skeletomuscular system of the mesosoma of Formica rufa workers (Hymenoptera: Formicidae)

Lazzat Aibekova, Brendon Boudinot, Rolf Beutel, Adrian Richter, Roberto Keller, Francisco Hita Garcia & Evan Economo
The mesosoma is the power core of the ant, containing critical structural and muscular elements for the movement of the head, legs, and metasoma. It has been hypothesized that adaptation to ground locomotion and the loss of flight led to the substantial rearrangements in the mesosoma in worker ants, and that it is likely the ant mesosoma has undergone functional modifications as ants diversified into different ecological and behavioral niches. Despite this importance, studies on...

A roadmap to reconstructing muscle architecture from CT data

Julian Katzke, Pavel Puchenkov, Evan P. Economo & Heiko Stark
Skeletal muscle is responsible for voluntary force generation across animals, and muscle architecture largely determines the parameters of mechanical output. The ability to analyze muscle performance through muscle architecture is thus a key step towards better understanding the ecology and evolution of movements and morphologies. In pennate skeletal muscle, volume, fiber lengths and attachment angles to force transmitting structures comprise the most relevant parameters of muscle architecture. Measuring these features through tomographic techniques offers an...

Arthropod (per year, 2008-2017) and environmental data (climate, land use, land cover) from grasslands used in \"Unravelling insect declines: can space replace time?\", Biology Letters

Michael Staab & Nico Blüthgen
To compare trends in arthropod species numbers between space and time, arthropod data from the sweep net samples (2008-2017) in grasslands were used. We tested whether trends over time are also found within single years (i.e. in space). The dataset contains, pooled per sampling year, arthropod individual numbers (Araneae, Coleoptera, Hemiptera, Orthoptera) and associated environmental data (climate, land use, land cover). This data is only to complement the publication "Unravelling insect declines: can space replace...

Soil fungal (ITS) communities from 10 grassland plots in Germany (2015-2018; Illumina MiSeq) - OTU taxonomic function look-up table (subset of dataset 25426)

Anna Abrahão & Ali Nawaz
Cooperation between the BE projects SADE, Scalemic, Microorganisms (core): Plant-soil feedbacks (PSFs) underlying grassland plant richness and productivity are typically coupled with nutrient availability; however, we lack understanding of how restoration measures to increase plant diversity might affect PSFs. We examined the roles of sward disturbance, seed addition and land-use intensity (LUI) on PSFs. We conducted a disturbance and seed addition experiment in ten grasslands along a LUI gradient and characterized plant biomass and richness,...

Annual occupancy estimates for butterflies, grasshoppers and dragonflies in Bavaria (Germany), 1980-2019

Eva Katharina Engelhardt, Matthias F. Biber, Matthias Dolek, Thomas Fartmann, Axel Hochkirch, Jan Leidinger, Franz Löffler, Stefan Pinkert, Dominik Poniatowski, Johannes Voith, Michael Winterholler, Dirk Zeuss, Diana E. Bowler & Christian Hof
Recent climate and land-use changes are having substantial impacts on biodiversity, including population declines, range shifts, and changes in community composition. However, few studies have compared these impacts among multiple taxa, particularly because of a lack of standardized time series data over long periods. Existing datasets are typically of low resolution or poor coverage, both spatially and temporally, thereby limiting the inferences that can be drawn from such studies. Here, we compare climate and land-use...

Soil bacterial (16S) communities from 10 grassland plots in Germany (2015-2018; Illumina MiSeq) - OTU taxonomic look-up table (subset of dataset 25466)

Data supplement to: Quality control of image sensors using gaseous tritium light sources

David McFadden, Brad Amos & Rainer Heintzmann
In the article “Quality Control of Image Sensors using Gaseous Tritium Light Sources” (https://doi.org/10.1098/rsta.2021.0130) we propose a practical method for radiometrically calibrating cameras using widely available gaseous tritium light sources (betalights). This dataset includes all the recorded data along with the scripts necessary to reproduce the results and figures.

Once an optimist, always an optimist? Studying cognitive judgment bias in mice

Marko Bračić, Lena Bohn, Viktoria Siewert, Vanessa Von Kortzfleisch, Holger Schielzeth, Sylvia Kaiser, Norbert Sachser & S. Helene Richter
This repository contains raw data and analysis code for the manuscript entitled "Once an Optimist, Always an Optimist? Studying Cognitive Judgment Bias in Mice" from Marko Bračić, Lena Bohn, Viktoria Siewert, Vanessa von Kortzfleisch, Holger Schielzeth, Sylvia Kaiser, Norbert Sachser, S. Helene Richter, accepted for publication in the journal Behavioral Ecology. The aim of the study was to investigate the causes and stability of cognitive judgment bias (aka "optimism"). Individuals differ in the way they...

Effect of drought and nutrient availability on invaded plant communities in a semi-arid ecosystem

Hamada Ali & Solveig Franziska Bucher
Ecosystem functions are heavily dependent on the functional composition of the plant community, i.e., the functional traits of plants forming the community. This, on the one hand, depends on plant occurrence, but on the other hand depends on the intraspecific variability of functional traits of the species, which are influenced by climate and nutrient availability and affected by plant-plant interactions. To illustrate that, we studied the effects of drought and nitrogen addition (+ N), two...

Eco-evolutionary dynamics modulate plant responses to global change depending on plant diversity and species identity

Peter Dietrich, Jens Schumacher, Nico Eisenhauer & Christiane Roscher
Global change has dramatic impacts on grassland diversity. However, little is known about how fast species can adapt to these changes and how this affects their responses to global change. To close this gap, we performed a common garden experiment testing whether plant responses to global change are influenced by the selection history of the plants and the conditioning history of soil at different levels of plant diversity. Therefore, we collected seeds and took soil...

Long-term (1901-2017) phenology data of 20 forest understory herbs in Europe, collected from herbaria and GBIF, used in: \"Forest wildflowers bloom earlier as Europe warms: Lessons from herbaria and spatial modeling\", New Phytologist

Franziska Merle Willems
Today plants often flower earlier due to climate warming, and the collection dates of herbarium specimens can provide proof of this.
To test for such fingerprints of climate change in Europe, we compiled a long-term (1901-2017) dataset from 6131 herbarium specimens of 20 early-flowering European forest understory herbs. The data were collected in the herbaria of Jena (JE), Stuttgart (STU) and Tübingen (TUB), and were complemented with herbarium data from the database GBIF.
The final data file...

Data and code from: Functional rarity of plants in German hay meadows - patterns on the species level and mismatches with community species richness

Gabriel Walther, Ute Jandt, Jens Kattge & Christine Römermann
Functional rarity (FR) - a feature combining a species’ rarity with the distinctiveness of its traits - represents a promising tool to better understand the ecological importance of rare species and consequently to protect functional diversity more efficiently. Yet, we lack a systematic understanding of FR on both the species level (which species are functionally rare and why) and the community level (how is FR associated with biodiversity and environmental conditions). Here, we quantify FR...
