Data from: Tandem-running and scouting behavior are characterized by up-regulation of learning and memory formation genes within the ant brain

Austin Alleman, Marah Stoldt, Barbara Feldmeyer & Susanne Foitzik
Tandem-running is a recruitment behavior in ants that has been described as a form of teaching, where spatial information possessed by a leader is conveyed to following nestmates. Within Temnothorax ants, tandem-running is used within a variety of contexts, from foraging and nest relocation to – in the case of slavemaking species – slave raiding. Here, we elucidate the transcriptomic basis of scouting, tandem-leading, and tandem-following behavior across two species with divergent lifestyles: the slavemaking...

Anatomical studies of leaflets of species from the plant subfamily Tribuloideae (Zygophyllaceae)

Maximilian Lauterbach & Gudrun Kadereit
Leaflets of 26 accessions of species from subfamily Tribuloideae (Zygophyllaceae), using herbarium material, were sectioned after chemical fixation and embedding. For each section, the area of the mesophyll (M) tissue, bundle sheath (BS) tissue, and vascular tissue were measured, as well as the BS area, BS distance, and interveinal distance. The ratio of BS to M areas was also calculated. With a molecular phylogeny as a guide, these leaf anatomical traits, which are typically altered...

Genetic admixture despite ecological segregation in a North African sparrow hybrid zone (Aves, Passeriformes, Passer domesticus x Passer hispaniolensis)

Martin Päckert, Abdelkrim Belkacem, Hannes Wolfgramm, Oliver Gast, David Canal, Gabriele Giacalone, Mario Lo Valvo, Melita Vamberger, Michael Wink, Jochen Martens & Heiko Stuckas
Under different environmental conditions hybridization between the same species might result in different patterns of genetic admixture. Particularly, species pairs with large distribution ranges and long evolutionary history may have experienced several independent hybridization events over time in different zones of overlap. In birds, the diverse hybrid populations of the house sparrow (Passer domesticus) and the Spanish sparrow (P. hispaniolensis) provide a striking example. Throughout their range of sympatry, these two species do not regularly...

Data from: An identification of invariants in life history traits of amphibians and reptiles

Konstantin Hallmann & Eva Maria Griebeler
While many morphological, physiological, and ecological characteristics of organisms scale with body size, some do not change under size transformation. They are called invariant. A recent study recommended five criteria for identifying invariant traits. These are based on that a trait exhibits a unimodal central tendency and varies over a limited range with body mass (type I), or that it does not vary systematically with body mass (type II). We methodologically improved these criteria and...

Data from: Quantitative PCR primer design affects quantification of dsRNA-mediated gene knockdown

Thomas Onchuru & Martin Kaltenpoth
RNA interference (RNAi) is a powerful tool for studying functions of candidate genes in both model and non-model organisms and a promising technique for therapeutic applications. Successful application of this technique relies on the accuracy and reliability of methods used to quantify gene knockdown. With the limitation in the availability of antibodies for detecting proteins, quantitative PCR (qPCR) remains the preferred method for quantifying target gene knockdown after dsRNA treatment . We evaluated how qPCR...

Angiosperm to Gymnosperm host-plant switch entails shifts in microbiota of the Welwitschia bug, Probergrothius angolensis (Distant, 1902)

Adam Martinez, Martin Kaltenpoth, Mario Sandoval-Calderón, Chantal Ingham, Juergen Deckert, Hassan Salem & Thomas Onchuru
Adaptation of herbivorous insects to new host plants is key to their evolutionary success in diverse environments. Many insects are associated with mutualistic gut bacteria that contribute to the host’s nutrition and can thereby facilitate dietary switching in polyphagous insects. However, how gut microbial communities differ between populations of the same species that feed on different host plants remains poorly understood. Most species of Pyrrhocoridae (Hemiptera: Heteroptera) are specialist seed-feeders on plants in the family...

Data from: The way wear goes – phytolith-based wear on the dentine-enamel system in guinea pigs (Cavia porcellus)

Louise F. Martin, Daniela Winkler, Thomas Tütken, Codron Daryl, Annelies De Cuyper, Jean-Michel Hatt & Marcus Clauss
The effect of phytoliths on tooth wear and function has been contested in studies of animal plant interactions. For herbivores whose occlusal chewing surface consists of enamel ridges in dentine tissue, the phytoliths might first erode the softer dentine, exposing the enamel ridges to different occlusal forces and thus leading to enamel wear. To test this hypothesis, we fed guinea pigs (Cavia porcellus; n=36 in 6 groups) for three weeks exclusively on dry or fresh...

Differential contributions of the two human cerebral hemispheres to action timing

Florian Gompf, Anja Pflug, Muthuraman Muthuraman, Sergiu Groppa & Christian Alexander Kell
Rhythmic actions benefit from synchronization with external events. Auditory-paced finger tapping studies indicate the two cerebral hemispheres preferentially control different rhythms. It is unclear whether left-lateralized processing of faster rhythms and right-lateralized processing of slower rhythms bases upon hemispheric timing differences that arise in the motor or sensory system or whether asymmetry results from lateralized sensorimotor interactions. We measured fMRI and MEG during symmetric finger tapping, in which fast tapping was defined as auditory-motor synchronization...
