Data from: On the occurrence of three non-native cichlid species including the first record of a feral population of Pelmatolapia (Tilapia) mariae (Boulenger, 1899) in EuropeJuliane A. Y. Lukas, Jonas Jourdan, Gregor Kalinkat, Sebastian Emde, Friedrich Miesen, Hannah Jüngling, Berardino Cocchiararo & David Bierbach
Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges. In Germany, non-native convict cichlids (Amatitlania nigrofasciata) and tilapia (Oreochromis sp.) have established populations in the Gillbach, a small stream that receives warm water discharge from a local power plant. Here, we report on the discovery of spotted tilapia (Pelmatolapia mariae) in the Gillbach, the first record of a reproducing...
The disruption of coupling between brain areas has been suggested as the mechanism underlying loss of consciousness in anesthesia. This hypothesis has been tested previously by measuring the information transfer between brain areas, and by taking reduced information transfer as a proxy for decoupling. Yet, information transfer is a function of the amount of information available in the information source—such that transfer decreases even for unchanged coupling when less source information is available. Therefore, we...
Data from: Chironomus riparius (Diptera) genome sequencing reveals the impact of minisatellite transposable elements on population divergenceAnn-Marie Oppold, Hanno Schmidt, Marcel Rose, Sören Lukas Hellman, Florian Dolze, Fabian Ripp, Bettina Weich, Urs Schmidt-Ott, Erwin Schmidt, Robert Kofler, Thomas Hankeln & Markus Pfenninger
Active transposable elements (TEs) may result in divergent genomic insertion and abundance patterns among conspecific populations. Upon secondary contact, such divergent genetic backgrounds can theoretically give rise to classical Dobzhansky-Muller incompatibilities (DMI), thus contributing to the evolution of endogenous genetic barriers and eventually cause population divergence. We investigated differential TE abundance among conspecific populations of the non-biting midge Chironomus riparius and evaluated their potential role in causing endogenous genetic incompatibilities between these populations. We focussed...
Data from: How weather instead of urbanity measures affects song trait variability in three European passerine bird speciesJulia E. Schäfer, Marcel M. Janocha, Sebastian Klaus & Dieter Thomas Tietze
Previous studies detected an influence of urban characteristics on song traits in passerine birds, that is, song adjustments to ambient noise in urban areas. Several studies already described the effect of weather conditions on the behavior of birds, but not the effect on song traits. We investigate, if song trait variability changes along a continuous urbanity gradient in Frankfurt am Main, Germany. We examined, for the first time on a larger scale, the influence of...
Data from: Seed-dispersal networks respond differently to resource effects in open and forest habitatsMaximilian G. R. Vollstaedt, Stefan W. Ferger, Andreas Hemp, Kim M. Howell, Katrin Böhning-Gaese & Matthias Schleuning
While patterns in species diversity have been well studied across large-scale environmental gradients, little is known about how species' interaction networks change in response to abiotic and biotic factors across such gradients. Here we studied seed-dispersal networks on 50 study plots distributed over ten different habitat types on the southern slopes of Mt. Kilimanjaro, Tanzania, to disentangle the effects of climate, habitat structure, fruit diversity and fruit availability on different measures of interaction diversity. We...
Data from: Adaptive differentiation coincides with local bioclimatic conditions along an elevational cline in populations of a lichen-forming fungusFrancesco Dal Grande, Rahul Sharma, Anjuli Meiser, Gregor Rolshausen, Burkhard Buedel, Bagdevi Mishra, Marco Thines, Juergen Otte, Markus Pfenninger & Imke Schmitt
Background: Many fungal species occur across a variety of habitats. Particularly lichens, fungi forming symbioses with photosynthetic partners, have evolved remarkable tolerances for environmental extremes. Despite their ecological importance and ubiquity, little is known about the genetic basis of adaption in lichen populations. Here we studied patterns of genome-wide differentiation in the lichen-forming fungus Lasallia pustulata along an altitudinal gradient in the Mediterranean region. We resequenced six populations as pools and identified highly differentiated genomic...
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: Quantifying the climatic niche of symbiont partners in a lichen symbiosis indicates mutualist-mediated niche expansionsGregor Rolshausen, Francesco Dal Grande, Anna Sadowska-Deś, Juergen Otte & Imke Schmitt
The large distributional areas and ecological niches of many lichenized fungi may in part be due to the plasticity in interactions between the fungus (mycobiont) and its algal or cyanobacterial partners (photobionts). On the one hand, broad-scale phylogenetic analyses show that partner compatibility in lichens is rather constrained and shaped by reciprocal selection pressures and codiversification independent of ecological drivers. On the other hand, sub-species-level associations among lichen symbionts appear to be environmentally structured rather...
Data from: Cross-taxa generalities in the relationship between population abundance and ambient temperaturesDiana E. Bowler, Peter Haase, Christian Hof, Ingrid Kröncke, Léon Baert, Wouter Dekoninck, Sami Domisch, Frederik Hendrickx, Thomas Hickler, Hermann Neumann, Robert B. O'Hara, Anne F. Sell, Moritz Sonnewald, Stefan Stoll, Michael Türkay, Roel Van Klink, Oliver Schweiger, Rikjan Vermeulen & Katrin Boehning-Gaese
Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and...
Data from: Genotypic diversity in root-endophytic fungi reflects efficient dispersal and environmental adaptationKyriaki Glynou, Tahir Ali, Sevda Haghi Kia, Marco Thines & Jose G. Macia-Vicente
Studying community structure and dynamics of plant-associated fungi is the basis for unravelling their interactions with hosts and ecosystem functions. A recent sampling revealed that only a few fungal groups, as defined by internal transcribed spacer region (ITS) sequence similarity, dominate culturable root endophytic communities of nonmycorrhizal Microthlaspi spp. plants across Europe. Strains of these fungi display a broad phenotypic and functional diversity, which suggests a genetic variability masked by ITS clustering into operational taxonomic...
