Sowohl die öffentliche Diskussion des Themas „Altern“, die stark von sozio-politischen, medizinischen oder ökonomischen Beiträgen geprägt ist, als auch die gängige kulturwissenschaftliche Beschäftigung damit stellen „Alter“ als individuelle und soziale Belastung in den Mittelpunkt. Es bleibt dabei weitgehend unbeachtet, wie sehr auf diese Weise die negative Bestimmung von „Alter“ durch die Öffentlichkeit verfestigt und die vom Individuum vorgenommene lebensbejahende Gestaltung der Zeitlichkeit von Existenz, wozu das intergenerationale Verhältnis zu zählen ist, außer Acht gelassen wird....

Data from: Molecular investigation of genetic assimilation during the rapid adaptive radiations of East African cichlid fishesHelen M. Gunter, Ralf F. Schneider, Immanuel Karner, Christian Sturmbauer & Axel Meyer
Adaptive radiations are characterized by adaptive diversification intertwined with rapid speciation within a lineage resulting in many ecologically specialized, phenotypically diverse species. It has been proposed that adaptive radiations can originate from ancestral lineages with pronounced phenotypic plasticity in adaptive traits, facilitating ecologically-driven phenotypic diversification that is ultimately fixed through genetic assimilation of gene regulatory regions. This study aimed to investigate how phenotypic plasticity is reflected in gene expression patterns in the trophic apparatus of...
Sphagnum bog ecosystems are among the oldest vegetation forms harboring a specific microbial community and are known to produce an exceptionally wide variety of bioactive substances. Although the Sphagnum metagenome shows a rich secondary metabolism, the genes have not yet been explored. To analyze nonribosomal peptide synthetases (NRPSs) and polyketide synthases (PKSs), the diversity of NRPS and PKS genes in Sphagnum-associated metagenomes was investigated by in silico data mining and sequence-based screening (PCR amplification of...
Intraspecific variability in mating behavior and disparities between social and reproductive behavior add complexity to the description of animal mating systems. A previously published field study on a population of the maternally mouthbrooding cichlid fish Ctenochromis horei in the north of Lake Tanganyika suggested mate monopolization by the most dominant male. In the present study, genetic reconstructions of paternity in a population in the south of the lake provided no evidence for male mate monopolization,...
Data from: Same school, different conduct: rates of multiple paternity vary within a mixed-species breeding school of semi-pelagic cichlid fish (Cyprichromis spp.)Caleb Anderson, Alexandra Werdenig, Stephan Koblmueller & Kristina M. Sefc
Mating system variability is known to exist between and within species, often due to environmental influences. An open question is whether, vice versa, similar environmental conditions entail congruent mating behavior, for example in terms of multiple paternity, in species or populations sharing largely comparable breeding modes. This study employed microsatellite markers to investigate the incidence of multiple paternity in Cyprichromis coloratus and Cyprichromis leptosoma, two sympatric, closely related, mouthbrooding Lake Tanganyika cichlids with similar ecological...

In eusocial honey bees, Apis mellifera, diet, gut microbiota and nestmates can all contribute to the health of freshly-emerged individual workers, but their relative importance for longevity and body weight is currently unknown. Here, we show that diet is most relevant, followed by gut microbiota and the presence of nestmates. Freshly emerged workers were randomly assigned to eight treatments (with or without honey/pollen, protein-substitute lactalbumin, antibiotic tetracycline and nestmates for 24 h) and maintained under...
Data from: Separated by sand, fused by dropping water: habitat barriers and fluctuating water levels steer the evolution of rock-dwelling cichlid populations in Lake TanganyikaStephan Koblmüller, Walter Salzburger, Beate Obermüller, Eva Eigner, Christian Sturmbauer & Kristina M Sefc
The conditions of phenotypic and genetic population differentiation allow inferences about the evolution, preservation and loss of biological diversity. In Lake Tanganyika, water level fluctuations are assumed to have had a major impact on the evolution of stenotopic littoral species, though this hypothesis has not been specifically examined so far. The present study investigates whether subtly differentiated color patterns of adjacent Tropheus moorii populations are maintained in isolation or in the face of continuous gene...
Data from: Male courtship preferences demonstrate discrimination against allopatric colour morphs in a cichlid fishPeter Zoppoth, Stephan Koblmüller & Kristina M. Sefc
Whether premating isolation is achieved by male-specific, female-specific or sex-independent assortative preferences often depends on the underlying evolutionary processes. Here we test mate preferences of males presented with females of different allopatric colour variants of the cichlid fish Tropheus, a Lake Tanganyika endemic with rich geographic colour pattern variation, in which the strength of sexual isolation varies between populations. We conducted two-way mate choice experiments to compare behaviour of males of a red-bodied morph (population...
Data from: Escape from the cryptic species trap: lichen evolution on both sides of a cyanobacterial acquisition eventKevin Schneider, Philipp Resl & Toby Spribille
Large, architecturally complex lichen symbioses arose only a few times in evolution, increasing thallus size by orders of magnitude over those from which they evolved. The innovations that enabled symbiotic assemblages to acquire and maintain large sizes are unknown. We mapped morphometric data against an eight-locus fungal phylogeny across one of the best-sampled thallus size transition events, the origins of the Placopsis lichen symbiosis, and used a phylogenetic comparative framework to explore the role of...
Lichens exhibit varying degrees of specialization with regard to the surfaces they colonize, ranging from substrate generalists to strict substrate specialists. Though long recognized, the causes and consequences of substrate specialization are poorly known. Using a phylogeny of a 150-200 MYA clade of lichen fungi, we asked whether substrate niche is phylogenetically conserved, which substrates are ancestral, whether specialists arise from generalists or vice versa, and how specialization affects speciation/extinction processes. We found strong phylogenetic...
Background: In socially monogamous species, reproduction is not always confined to paired males and females. Extra-pair males commonly also reproduce with paired females, which is traditionally thought to be costly to the females’ social partners. However, we suggest that when the relatedness between reproducing individuals is considered, cuckolded males can suffer lower fitness losses than otherwise expected, especially when the rate of cuckoldry is high. We combine theoretical modeling with a detailed genetic study on...
Congruent geographic variation in saccular otolith shape across multiple species of African cichlidsAneesh Bose, Holger Zimmermann, Georg Winkler, Alexandra Kaufmann, Thomas Strohmeier, Stephan Koblmüller & Kristina Sefc
The otoliths of teleost fishes exhibit a great deal of inter- and intra-species shape variation. The ecomorphology of the saccular otolith is often studied by comparing its shape across species and populations inhabiting a range of environments. However, formal tests are often lacking to examine how closely variation in otolith shape follows the genetic drift of a neutral trait. Here, we examine patterns of saccular otolith shape variation in four species of African cichlid fishes,...
