This Dataset supports the article "Inbreeding in a dioecious plant has sex- and population origin-specific effects on its interactions with pollinators", which is published in eLife. The study addresses the combined effects of inbreeding, plant sex and plant population origin on interactions among plants and their specialised pollinators. It contains data on various floral traits (spatial flower traits, flower colour traits, floral scent traits (floral VOC), floral rewards) as well as pollinator visitation rates. The...

Robert Kopte & Marius Becker
Upper-ocean velocities along the cruise track of Maria S. Merian cruise MSM97/2 were continuously collected by a vessel-mounted Teledyne RD Instruments 75 kHz Ocean Surveyor ADCP. The transducer was located at 6.5 m below the water line. The instrument was operated in narrowband mode with 8 m bins and a blanking distance of 8 m, while 100 bins were recorded using a pulse of 1.42 s. The ship's velocity was calculated from position fixes obtained...

Delayed color maturation of a sexual ornament in males of a damselfly: crypsis, female mimicry or both?

Rodrigo Cezário, Eralci Therezio, Alexandre Marletta, Stanislav Gorb & Rhainer Guillermo-Ferreira
Dynamic signals are a widespread phenomenon in several taxa, usually associated with intraspecific communication. On the other hand, dynamic iridescent signals are only detectable at specific angles of illumination; hence, the animal can hide the signal to avoid detection when necessary. This structural coloration is mostly dependent on illumination, contrast against the background and the vision of the receiver. Complex behavioural displays may be coupled with structural coloration to create dynamic visual signals that enhance...

Biodiversity citizen science: outcomes for the participating citizens

Maria Peter, Tim Diekötter, Tim Höffler & Kerstin Kremer
1. Citizen science (CS) is regarded a promising format in environmental and sustainability education as well as in science education. CS projects often assume that participation in the project influences, for example, participants' knowledge or behaviour. 2. We investigated whether and to what extent biodiversity citizen science (BDCS) projects, from the participants' self-reported perspective, achieve the following six participant outcomes: (1) content, process, and nature of science knowledge, (2) skills of science inquiry, (3) self-efficacy...

Continuous thermosalinograph oceanography along RV Maria S. Merian cruise MSM98/2

Michael Schlundt & Jens Schneider von Deimling
Underway temperature and salinity data was collected along the cruise track with two autonomous measurement systems. Usually, the systems are changed after 6 hours. While temperature is taken at the water inlet in about 6.5 m depth, salinity is estimated within the interior measurement container from conductivity and interior temperature. Salinity was calibrated independently for both measurement containers (MCs). No correction was done for temperature. For details to all processing steps see Data Processing Report.

Breaking force Spekia

Wencke Krings, Alexander Kovalev & Stanislav N. Gorb
One molluscan autapomorphy is the radula, the organ used for feeding. Here, for the first time, the performance and failure of taenioglossan radular teeth were tested in a biomechanical experiment which in turn allowed building hypotheses about tooth functionalities. Shear load was applied to tooth cusps with a force transducer until structural failure occurred, the broken area was measured, and finally breaking stress was calculated. These experiments were carried out under dry and wet conditions....

Data from: A multi-taxa assessment of the effectiveness of agri-environmental schemes for biodiversity management

Fabian A. Boetzl, Jochen Krauss, Jonathan Heinze, Hannes Hoffmann, Jan Juffa, Sebastian König, Elena Krimmer, Maren Prante, Emily A. Martin, Andrea Holzschuh & Ingolf Steffan-Dewenter
Agri-environmental schemes (AES) aim to restore biodiversity and biodiversity-mediated ecosystem services in landscapes impoverished by modern agriculture. However, a systematic, empirical evaluation of different AES types across multiple taxa and functional groups is missing. Within one orthogonal design, we studied sown flowering AES types with different temporal continuity, size, and landscape context and used calcareous grasslands as semi-natural reference habitat. We measured species richness of twelve taxonomic groups (vascular plants, cicadas, orthopterans, bees, butterflies, moths,...

Data from: Timing of spring departure of long distance migrants correlates with previous year's conditions at their breeding site

Françoise Amélineau, Nicolas Delbart, Philipp Schwemmer, Riho Marja, Jérôme Fort, Stefan Garthe, Jaanus Elts, Philippe Delaporte, Pierre Rousseau, Françoise Duraffour & Pierrick Bocher
Precise timing of the migration is crucial for animals targeting seasonal resources at locations encountered across their annual cycle. Upon departure, long distance migrants need to anticipate unknown environmental conditions at their arrival site, and they do zkzdsxso with their internal annual clock. Here, we tested the hypothesis that long distance migrants synchronize their circannual clock according to the phenology of their environment during the breeding season, and therefore adjust their spring departure date according...

Rewetting does not return drained fen peatlands to their old selves

Juergen Kreyling, Franziska Tanneberger, Florian Jansen, Sebastian Van Der Linden, Camiel Aggenbach, Volker Blüml, John Couwenberg, Willem-Jan Emsens, Hans Joosten, Agatha Klimkowska, Wiktor Kotowski, Lukasz Kozub, Bernd Lennartz, Yvonne Liczner, Haojie Liu, Dierk Michaelis, Claudia Oehmke, Karsten Parakenings, Elisabeth Pleyl, Arne Poyda, Stefanie Raabe, Markus Röhl, Kirsten Rücker, Anett Schneider, Joachim Schrautzer … & Gerald Jurasinski
Peatlands, in particular groundwater-fed fens of the temperate zone, have been drained for agriculture, forestry and peat extraction for a long time and on a large scale. Drainage turns peatlands from a carbon and nutrient sink into a respective source, diminishes water regulation capacity at the landscape scale, causes continuous surface height loss and destroys their typical biodiversity. Over the last decades, drained peatlands have been rewetted for biodiversity restoration and, as it strongly decreases...

Pollinator community predicts trait-matching between oil-producing flowers and a guild of oil-collecting bees

Hilke Hollens-Kuhr, Timotheüs Van Der Niet, Ruth Cozien & Michael Kuhlmann
The impact of pollinator community diversity on trait-matching in plant-pollinator interactions is poorly studied, even though many mutualisms involve multiple interaction partners. We studied ten communities in which one to three species of oil-collecting Rediviva bee pollinate the long-spurred, oil-producing flowers of Diascia ‘floribunda’ to examine how pollinator diversity affects covariation of functional traits across sites and trait-matching within sites. Floral spur-length was significantly correlated with weighted grand mean foreleg length of the local bee...

Experimental data for Pseudomonas aeruginosa from experimental evolution under different bottleneck sizes and antibiotic selection pressures

Hinrich Schulenburg
We here combined evolution experiments with genomic and genetic analyses to assess whether bottleneck size and antibiotic-induced selection influences the evolutionary path to resistance in pathogenic Pseudomonas aeruginosa, one of the most problematic opportunistic human pathogens. Two sets of evolution experiments were performed across 16 transfers, in which either the aminoglycoside gentamicin or the fluoroquinolone ciprofloxacin were used as antibiotic. The evolutionary response was studied using counts of bacterial cells at the end of each...

Genome-wide association study in quinoa reveals selection pattern typical for crops with a short breeding history

Dilan Sarange Rajapaksha Patiranage, Elodie Rey, Nazgol Emrani, Gordon Wellman, Karl Schmid, Sandra Schmöckel, Mark Tester & Christian Jung
Quinoa germplasm preserves useful and substantial genetic variation, yet it remains untapped due to a lack of implementation of modern breeding tools. We have integrated field and sequence data to characterize a large diversity panel of quinoa. Whole-genome sequencing of 310 accessions revealed 2.9 million polymorphic high confidence SNP loci. Highland and Lowland quinoa were clustered into two main groups, with FST divergence of 0.36 and fast LD decay of 6.5 and 49.8 Kb, respectively....
