Rationale, aims and objectives Improving the possibilities for ageing persons to take control over their health is an increasingly important public health issue. Health promotion has previously been visualized to succeed with this goal, but research has primarily focused on ageing persons who are native-born, leaving the generalizability to persons who are foreign-born unexplored. Therefore, as part of the development of a larger health promotion initiative for ageing persons who have experienced migration, this study aimed to assess the feasibility of an adapted protocol. The specific feasibility objectives were to assess recruitment procedure, retention rates, study questionnaire administration and variability of collected data. Method Forty persons who were ≥70 years, and who had migrated from Finland, Bosnia and Herzegovina, Croatia, Montenegro or Serbia to Sweden were randomly allocated to a health promotion programme or a control group. The programme was linguistically adapted with regard to translated information material, bilingual health professionals and evaluators, and a person-centred approach was applied to both programme development and provision. The data analysis was explorative and descriptive. Results The results visualized structural and linguistic barriers to recruitment and study questionnaire administration, and describe strategies for how to bridge them. Retention rates and data variability were satisfying. Conclusions Calling for iterative and pragmatic programme design, the findings describe how to move towards a more inclusive health care environment. Person-centred and bilingual approaches with attention to the possibilities for building authentic relationships between participants and providers are emphasized, and a structured methodology for developing study questionnaires is suggested.

Adaptations and, counteradaptations are common in coevolving predatorprey systems, but little is known of the role of maternal transfer of adaptive traits in mediating species interactions. Here, we focused on tolerance against cyanobacterial toxins and asked whether this tolerance was an induced defense developed during Daphnia's lifetime, whether it was a trait that is constantly expressed, and whether such tolerance to the toxin can be transferred to the next generation through maternal effects. These questions were addressed by feeding a single clone of Daphnia magna a diet with and without algal toxin and recording changes in fitness (as intrinsic rate of population increase). Analysis of F1, F2, and F3 generations revealed that the increased tolerance to toxic Microcystis was an inducible defense developed during an individual's lifetime, and that this trait could be transferred from mother to offspring. This maternal effect was expressed in several fitness parameters, including shorter time to maturity and first reproduction, and higher numbers of offspring compared to inexperienced individuals. In some circumstances, such maternal effects may increase population production by up to 40% and may help to stabilize material and energy transfer to higher trophic levels.

This investigation evaluates the usage of genetic markers, microsatellites, to distinguish and re-identify individual plants in a population of the orchid Gymnadenia conopsea. The study also illust ...

Six polymorphic microsatellite loci were found in two genomic libraries (one unenriched and one enriched) constructed using DNA originating from the fragrant orchid, Gymnadenia conopsea. These six microsatellite loci (Gc 17, 29, 42, 49, 51 and 77) showed high levels of variation (HO= 0.65, 0.90, 0.85, 0.75, 0.90 and 0.40, respectively) when 20 individuals from one population of G. conopsea were PCR amplified and separated in 6% PAA gels.
