Data from: Gastrointestinal microbiota of wild and inbred individuals of two house mouse subspecies assessed using high throughput parallel pyrosequencing

Jakub Kreisinger, Dagmar Čížková & Jaroslav Piálek
The effects of gastrointestinal tract microbiota (GTM) on host physiology and health has been the subject of considerable interest in recent years. While a variety of captive bred species have been used in experiments, the extent to which GTM of captive and/or inbred individuals resembles natural composition and variation in wild populations is poorly understood. Using 454 pyrosequencing, we performed 16S rDNA GTM barcoding for 30 wild house mice (Mus musculus) and wild-derived inbred strain...

Data from: Strategic exploitation of fluctuating asymmetry in male Endler's guppy courtship displays is modulated by social environment

Radomil Rezucha & Martin Reichard
Lateral asymmetry in signalling traits enables males to strategically exploit their best side. In many animals, both body colouration and fluctuating asymmetry are signals of male attractiveness. We demonstrated experimentally that even sexually naïve male Poecilia wingei were able to identify their most attractive side (i.e. that with a higher proportion of carotenoid pigmentation) and use it preferentially during courtship. Notably, males retained their strategic signalling in a male-biased social environment, whereas they ceased to...

Data from: PCR-based isolation of multigene families: lessons from the avian MHC class IIB

Reto Burri, Marta Promerová, Julien Goebel & Luca Fumagalli
The amount of sequence data available today highly facilitates the access to genes from many gene families. Primers amplifying the desired genes over a range of species are readily obtained by aligning conserved gene regions, and laborious gene isolation procedures can often be replaced by quicker PCR-based approaches. However, in the case of multigene families, PCR-based approaches bear the often ignored risk of incomplete isolation of family members. This problem is most prominent in gene...

Data from: The function of multiple ejaculations in bitterling

Carl Smith, Mark Warren, Romain Rouchet & Martin Reichard
In some taxa, males perform multiple ejaculations, which may function in sperm competition or in maintaining a baseline density of spermatozoa in the female reproductive tract to ensure fertilization, a process that has been termed ‘topping up’. We investigated the function of multiple ejaculations in two species of bitterling, the European bitterling (Rhodeus amarus) and Chinese rose bitterling (Rhodeus ocellatus). Bitterling oviposit in living freshwater mussels, with fertilization taking place within the mussel gill cavity....

Data from: Alternative intrapopulation life history strategies and their trade-offs in an African annual fish

Matej Polačik, Radim Blažek, Radomil Řežucha, Milan Vrtílek, Eva Terzibasi-Tozzini & Martin Reichard
In ephemeral habitats, the same genotypes cope with unpredictable environmental conditions, favouring the evolution of developmental plasticity and alternative life-history strategies (ALHS). We tested the existence of intrapopulation ALHS in an annual killifish, Nothobranchius furzeri, inhabiting temporary pools. The pools are either primary (persisting throughout the whole rainy season) or secondary (refilled after desiccation of the initial pool), representing alternative niches. The unpredictable conditions led to the evolution of reproductive bet-hedging with asynchronous embryonic development....
