Plant history and soil history jointly influence the selection environment for plant species in a long-term grassland biodiversity experiment

Peter Dietrich, Nico Eisenhauer, Peter Otto & Christiane Roscher
Long-term biodiversity experiments have shown increasing strengths of biodiversity effects on plant productivity over time. However, little is known about rapid evolutionary processes in response to plant community diversity, which could contribute to explaining the strengthening positive relationship. To address this issue, we performed a transplant experiment with offspring of seeds collected from four grass species in a 14-year old biodiversity experiment (Jena Experiment). We used two- and six-species communities and removed the vegetation of...

Southon, Alexander Burdin, Ming-Shan Wang, Sonja Grunewald, Wilfried Rosendahl, Ulrich Joger, Sereina Rutschmann, Thomas B. Hildebrandt, Guido Fritsch, James A. Estes, Janet Kelso, Love Dalén, Michael Hofreiter, Beth Shapiro & Torsten Schöneberg
Steller’s sea cow, an extinct sirenian and one of the largest Quaternary mammals, was described by Georg Steller in 1741 and eradicated by humans within 27 years. Here, we complement Steller’s descriptions with paleogenomic data from 12 individuals. We identified convergent evolution between Steller’s sea cow and cetaceans but not extant sirenians, suggesting a role of several genes in adaptation to cold environments. Among these are inactivations of lipoxygenase genes, which in humans and mouse...

Transport von Hühnern (Gallus gallus f. dom.) zur Schlachtung unter Berücksichtigung tierschutzrechtlicher/anatomisch‐physiologischer und fleischhygienischerGesichtspunkte

Krautwald-Junghanns, Christine Ahlers & Reinhard Fries
Im Rahmen eines Gutachtens für das Hessische Ministerium fürUmwelt, Klimaschutz, Landwirtschaft und Verbraucherschutz sollte ein aufwissenschaftlichen Erkenntnissen basierendes Sachverständigengutachtenüber den Transport von Hühnern zum Schlachthof erstellt werden. Die beschriebenenUntersuchungsparameter zur Einschätzung des Tierbefindenswaren einerseits indirekte Indikatoren wie zB Veränderungen im physiologischenund immunologischen Status und im Verhalten und andererseits direkteParameter wie die „Dead on Arrival“-Rate (DOA) der angeliefertenSchlachttiere. Prinzipiell beeinflussen viele Faktoren in diesem Kontext dieGesundheit von Geflügel. Dies sind ua der eigentliche Transport, das Fangenund...

Context-dependent dispersal determines relatedness and genetic structure in a patchy amphibian population

Bianca Unglaub, Hugo Cayuela, Benedikt R. Schmidt, Kathleen Preißler, Julian Glos & Sebastian Steinfartz
Dispersal is a central process in ecology and evolution with far reaching consequences for the dynamics and genetics of spatially structured populations (SSPs). Individuals can adjust their decisions to disperse according to local fitness prospects, resulting in context-dependent dispersal. By determining dispersal rate, distance, and direction, these individual-level decisions further modulate the demography, relatedness, and genetic structure of SSPs. Here, we examined how context-dependent dispersal influences the dynamics and genetics of a Great Crested Newt...

Biodiversity facets, canopy structure and surface temperature of grassland communities

Claudia Regina Guimaraes-Steinicke, Alexandra Weigelt, Raphaël Prouxl, Thomas Lanners, Nico Eisenhauer, Joaquín Duque-Lazo, Björn Reu, Christiane Roscher, Cameron Wagg, Nina Buchmann & Christian Wirth
Canopy structure is an important driver of the energy budget of the grassland ecosystem and is, at the same time, altered by plant diversity. Diverse plant communities typically have taller and more densely packed canopies than less diverse communities. With this, they absorb more radiation, have a higher transpiring leaf surface, and are better coupled to the atmosphere which leads to cooler canopy surfaces. However, whether plant diversity generally translates into a cooling potential remains...

Keramik der 1. bis 6. Dynastie auf Elephantine : Katalog der Formen und ihrer chronologischen Einordnung

Dietrich Raue
Der Band bietet einen umfassenden Katalog typologisch geordneter Profilzeichnungen keramischer Formen aus der Zeit des Alten Reiches (ca. 3000-2100 v.Chr.) aus den Ausgrabungen in der antiken Stadt Elephantine (Assuan / Ägypten) mit Angaben zum chronologischen Vorkommen der einzelnen Formen. Der Katalog bietet die Grundlage, keramische Fundkomplexe in einem System relativ- und absolutchronologischer Phasen zu datieren.

Juegos subversivos. Re-codificaciones de mitos cristianos en Frida Kahlo

Uta Felten
pp. 127-136. In our contribution we want to analyze how Frida Kahlo transforms the biographical space woven by pain into a pictorial heterotopic space of imagination that draws on the imaginary of the Christian textual and pictorial tradition and is woven into a palimpsestic structure in which Christian mythology overlaps with pre-Columbian mythology and popular Mexican mythology.

Structural heterogeneity of cellular K5/K14 filaments as revealed by cryo-electron microscopy

Miriam Sarah Weber, Matthias Eibauer, Suganya Sivagurunathan, Thomas Magin, Robert Goldman & Ohad Medalia
Keratin intermediate filaments are an essential and major component of the cytoskeleton in epithelial cells. They form a stable yet dynamic filamentous network extending from the nucleus to the cell periphery, which provides resistance to mechanical stresses. Mutations in keratin genes are related to a variety of epithelial tissue diseases. Despite their importance, the molecular structure of keratin filaments remains largely unknown. In this study, we analyzed the structure of keratin 5/keratin 14 filaments within...

Erfahrungen mit der Haltung von Bruderhähnen

Maria-Elisabeth Krautwald-Junghanns & Rebecca Grienberger
Die Aufzucht der männlichen Nachkommen der Legehennenlinien,die sog Bruderhahnmast, wird als eine der möglichen Alternativen zum Töten männlicher Eintagsküken angesehen. Im Rahmen eines Gutachtenauftragsfür das Hessische Ministerium für Umwelt, Klimaschutz, Landwirtschaft undVerbraucherschutz wurde zu dieser Thematik ein Literaturreview durchgeführt.Die wenigen wissenschaftlichen Publikationen zur Bruderhahnmastbeziehen sich größtenteils nicht auf die Haltung selbst, sondern eher aufLeistungsdaten und Daten zur Schlachtung. In Bezug auf die Tiergesundheitscheint die Aufzucht der Bruderhähne weitgehend unproblematisch. Erfahrungenaus der Legehennenhaltung können genutzt werden,...

Data from: Opsins in Onychophora (velvet worms) suggest a single origin and subsequent diversification of visual pigments in arthropods

Lars Hering, Miriam J. Henze, Martin Kohler, Almut Kelber, Christoph Bleidorn, Maren Leschke, Birgit Nickel, Matthias Meyer, Martin Kircher, Paul Sunnucks & Georg Mayer
Multiple visual pigments, prerequisites for color vision, are found in arthropods, but the evolutionary origin of their diversity remains obscure. In this study, we explore the opsin genes in five distantly related species of Onychophora, using deep transcriptome sequencing and screening approaches. Surprisingly, our data reveal the presence of only one opsin gene (onychopsin) in each onychophoran species, and our behavioral experiments indicate a maximum sensitivity of onychopsin to blue–green light. In our phylogenetic analyses,...

Effects of large herbivores on fire regimes and wildfire mitigation

Julia Rouet-Leduc, Guy Pe'er, Francisco Moreira, Aletta Bonn, Wouter Helmer, S. Alain Aidan Shahsavan Zadeh, Alexander Zizka & Fons Van Der Plas
1. Abandonment of agricultural land is widespread in many parts of the world, leading to shrub and tree encroachment. The increase of flammable plant biomass, i.e. fuel load, increases the risk and intensity of wildfires. Fuel reduction by herbivores is a promising management strategy to avoid fuel build-up and mitigate wildfires. However, their effectiveness in mitigating wildfire damage may depend on a range of factors, including herbivore type, population density and feeding patterns. 2. Here...

Proton-transfer-reaction time-of-flight mass spectrometry (PTR-TOF-MS) as a tool for studying animal volatile organic compound (VOC) emissions

Miguel Portillo-Estrada, Charlotte Van Moorleghem, Sunita Janssenswillen, Richard Joseph Cooper, Claudia Birkemeyer, Kim Roelants & Raoul Van Damme
1. Chemical sensing in vertebrates is crucial in their lives, and efforts are undertaken towards deciphering their chemical language. Volatile organic compounds (VOCs) is a group of chemicals believed to play an essential role in a wide variety of animal interactions. Therefore, understanding what animals sense themselves and untangling the ecological role of their volatile cues can be accomplished by analysing VOC emissions. A Proton-Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-TOF-MS) is an instrument that measures...
