Data from: Evolution of the selfing syndrome: anther orientation and herkogamy together determine reproductive assurance in a self-compatible plant
Capacity for autonomous self-fertilization provides reproductive assurance, has evolved repeatedly in the plant kingdom, and typically involves several changes in flower morphology and development (the selfing syndrome). Yet, the relative importance of different traits and trait combinations for efficient selfing and reproductive success in pollinator-poor environments is poorly known. In a series of experiments, we tested the importance of anther-stigma distance and the less studied trait anther orientation for efficiency of selfing in the perennial herb Arabis alpina. Variation in flower morphology among eight self-compatible European populations was correlated with efficiency of self-pollination and with pollen limitation in a common-garden experiment. To examine whether anther-stigma distance and anther orientation are subject to directional and/or correlational selection, and whether this is because these traits affect pollination success, we planted a segregating F2 population at two native field sites. Selection strongly favored a combination of introrse anthers and reduced anther-stigma distance at a site where pollinator activity was low, and supplemental hand-pollination demonstrated that this was largely because of their effect on securing self-pollination. The results suggest that concurrent shifts in more than one trait can be crucial for the evolution of efficient self-pollination and reproductive assurance in pollinator-poor habitats.
Data from: Case-oriented selection of investigation methods in direct access: A comparison between physiotherapy trainees at professional colleges and in bachelor's study courses
Objective: Direct access to physiotherapy services is currently discussed in Germany. Its introduction would mean that initial diagnoses must be made in physiotherapy practices as well. However, it was not yet investigated whether the current training in physiotherapy is sufficient for this, and whether there are differences between the training systems. This study aims to answer the question of whether trainees at the end of Bachelor's studies (BS) are more reliably able to assess the case-related suitability of examination methods than professional college students (FS). Methodology: Questionnaires were developed to assess the suitability of examination methods for diagnostic inquiries. All professional colleges and bachelor's study courses listed with the German Physiotherapy Association were asked to present the questionnaires to their final classes. Results: In 216 addressed professional colleges and 24 bachelor's study courses, the return rate was 9.26% for professional colleges and 33.33% for study courses. One hundred thirty-eight questionnaires from students in 8 study courses and 368 questionnaires from students at 20 professional colleges were evaluated. The mean of correct decisions in total (of max. 54) was 19.01 (BS) or 15.73 (FS); in structure-related and function-related examination methods (of max. 42), it was 17.22 (BS) and 14.8 (FS); in activity-related methods (of max. 12), it was 1.97 (BS) and 0.89 (FS). Out of a max. of 49 examination methods, 23.45 (BS) and 26.72 (FS) were stated as unknown. Conclusion: The university students made correct decisions on the suitability of examination methods significantly more frequently than the professional college students. However, the determined group difference is low. Overall, the results do not appear sufficient for direct access. Training would have to be adapted for this purpose.
Data from: Identification of an early male-killing agent in the oriental tea tortrix, Homona magnanima
Arthropods are frequently infected with inherited symbionts, which sometimes confer fitness benefits on female hosts or manipulate host reproduction. Early male killing, in which infected males die during embryogenesis, is induced by some bacteria, such as Wolbachia and Spiroplasma. A female-biased sex ratio has been found in Homona magnanima, collected from a tea plantation in Japan. Here, we examined the male-killing trait in H. magnanima and identified the agent that induces early male killing. The sex ratio distortion (SR) strain produced only females and no males, and its egg hatch rate was significantly lower than that of the normal (N) strain. The N strain was infected with only Wolbachia, whereas the SR strain was infected with both Wolbachia and Spiroplasma. Antibiotic treatment with 0.10% tetracycline restored the 1:1 sex ratio in the SR strain. Females treated with 0.05% tetracycline were positive for Spiroplasma but not for Wolbachia and showed a female-biased sex ratio, whereas Wolbachia-positive females did not revert to male killing. When inoculated with a homogenate of the SR strain female, females infected with only Spiroplasma produced female-biased offspring. Sequence analysis of the 16S rRNA gene revealed that Spiroplasma sp. of H. magnanima belonged to the ixodetis clade. These results indicate that Spiroplasma was responsible for male killing in H. magnanima. Late male killing is induced in H. magnanima by an RNA-like virus, and therefore this is the first case in which different male-killing agents expressed at different times in the life cycle have been found within one host species.
Data from: Phylogeography of poorly dispersing net-winged beetles: a role of drifting India in the origin of Afrotropical and Oriental fauna
Ancient dispersal history may be obscured by subsequent dispersal events. Therefore, we intend to investigate the biogeography of metriorrhynchine net-winged beetles, a group characterized by limited dispersal propensity. We used DNA data to construct phylogenies and the BayesTraits and RASP programs to identify putative ancestral areas. Further, we inferred ultrametric trees to estimate the ages of selected nodes. The time frame is inferred from tectonic calibrations and the general mutation rate of the mitochondrial genes. Metriorrhynchini consists of two lineages with Afro/Oriental and Australian distributions. The basal lineages originated in Eastern Gondwana after the split of Australia, India and Madagascar; the Afrotropical and Madagascar Metriorrhynchini separated from the Oriental clades 65 and 62 mya. Several already diversified lineages colonized continental Asia 55–35 mya. A few genera of the Australian clade dispersed to the Oriental region 5–15 mya and reached Eastern India and Southern China. Only Xylobanus crossed the Makassar Strait to Sulawesi and does not occur further to the east. The current distribution of Metriorrhynchini is a result of drifting on continental fragments and over-sea dispersal events limited to a few hundreds of kilometers. We conclude that: (1) Afrotropical and Madagascar lineages originated independently from dispersal events during India's drift to the north and the Mozambique Channel completely isolates the respective faunas since then; (2) Oriental fauna is a recently established mixture of the Indian and Australian lineages, with predominance of the older Indian clades; (3) The fauna of islands located north of Australia colonized Sulawesi after collision with the Sundaland margin and the species rich Australian lineages did not reach Western Wallacea or the Philippines. Our results suggest an impact of subtle differences in biological characteristics on biogeographic history of individual lineages, when mostly lowland and flower-visiting lineages were able to disperse across sea channels.
