Zur sächsischen Provenienz einer ungefassten Amethyst­schale aus der Wiener Kunstkammer (Inventarnummer KK 1697)

Ulf Kempe, Klaus Thalheim & Michael Wagner
In der Kunstkammer des Kunsthistorischen Museums in Wien wird unter der Inventarnummer KK 1697 eine ungefasste Amethystschale aufbewahrt, die bisher unter Nutzung stilistischer Kriterien in das 17. Jahrhundert datiert wurde und heute auf einem im 19. Jahrhundert gefertigten, gedrechselten hölzernem Fuß präsentiert wird. Eine nähere Begutachtung des Amethystes der Schale zeigt, dass es sich hierbei um das größte bisher bekannte geschnittene Objekt aus sogenanntem „Purschensteiner Amethyst“, einem historischen sächsischen Schmuckstein, handelt. Ein Vergleich der Inventare...

Genomic processes underlying rapid adaptation of a natural Chironomus riparius population to unintendedly applied experimental selection pressures

Markus Pfenninger & Quentin Foucault
Evolve and Resquence (E&R) studies are a useful tool to study genomic processes during rapid adaptation, e.g. in the framework of adaptive responses to global climate change. We applied different thermal regimes to a natural Chironomus riparius (Diptera) population in an E&R framework to infer its evolutionary potential for rapid thermal adaptation. We exposed two replicates to three temperatures each (14°C, 20°C and 26°C) for more than two years, the experiment thus lasting 22, 44...

Data from: ‘In and out of’ the Qinghai-Tibet Plateau and the Himalayas: centers of origin and diversification compared across five clades of Eurasian montane and alpine passerine birds

Martin Päckert, Adrien Favre, Jan Schnitzler, Jochen Martens, Yue-Hua Sun, Dieter Thomas Tietze, Frank Hailer, Ingo Michalak & Patrick Strutzenberger
Encompassing some of the major hotspots of biodiversity on Earth, large mountain systems have long held the attention of evolutionary biologists. The region of the Qinghai-Tibet Plateau (QTP) is considered a biogeographic source for multiple colonization events into adjacent areas including the northern Palearctic. The faunal exchange between the QTP and adjacent regions could thus represent a one-way street (‘out of’ the QTP). However, immigration into the QTP region has so far received only little...

An unbiased molecular approach using 3’UTRs resolves the avian family-level tree of life

Heiner Kuhl, Carolina Frankl-Vilches, Antje Bakker, Gerald Mayr, Gerhard Nikolaus, Stefan Boerno, Sven Klages, Bernd Timmermann & Manfred Gahr
Presumably, due to a rapid early diversification, major parts of the higher-level phylogeny of birds are still resolved controversially in different analyses or are considered unresolvable. To address this problem, we produced an avian tree of life, which includes molecular sequences of one or several species of ∼ 90% of the currently recognized family-level taxa (429 species, 379 genera) including all 106 for the non-passerines and 115 for the passerines (Passeriformes). The unconstrained analyses of...

Expanding the mutualistic niche: parallel symbiont turnover along climatic gradients

Gregor Rolshausen, Uwe Hallman, Francesco Dal Grande, Juergen Otte, Kerry Knudsen & Imke Schmitt
Keystone mutualisms, such as corals, lichens, or mycorrhizae sustain fundamental ecosystem functions. Range dynamics of these symbioses are, however, inherently difficult to predict because host species may switch between different symbiont partners in different environments, thereby altering the range of the mutualism as a functional unit. Biogeographic models of mutualisms thus have to consider both, the ecological amplitudes of various symbiont partners, and the abiotic conditions that trigger symbiont replacement. To address this challenge, we...
