Benchmarking of outdoor activity facilities : an analysis of German hiking facilities and its implications to Finland
2015
The health effects of regular physical activity play an integral part in the promotion of outdoor participation. Well-maintained and marketed outdoor facilities encourage in this regard people to be more active outside of their homes. The aim of this study is to analyse popular German outdoor facilities in order to identify good working practices in Germany that can potentially be applied in Finland with the purpose of encouraging Finnish people to go outdoors more often. The study was conducted in cooperation between the University of Jyväskylä and Suomen Latu. The main research questions was: What knowledge can Suomen Latu gain from the administration of popular German hiking facilities i…
Founder effects drive the genetic structure of passively dispersed aquatic invertebrates
2018
Populations of passively dispersed organisms in continental aquatic habitats typically show high levels of neutral genetic differentiation, despite their high dispersal capabilities. Several evolutionary factors, including founder events and local adaptation, and life cycle features such as high population growth rates and the presence of propagule banks, have been proposed to be responsible for this paradox. Here, we have modeled the colonization process in these organisms to assess the impact of migration rate, growth rate, population size, local adaptation and life-cycle features on their population genetic structure. Our simulation results show that the strongest effect on population st…
A genome-wide view of Caenorhabditis elegans base-substitution mutation processes
2009
Knowledge of mutation processes is central to understanding virtually all evolutionary phenomena and the underlying nature of genetic disorders and cancers. However, the limitations of standard molecular mutation detection methods have historically precluded a genome-wide understanding of mutation rates and spectra in the nuclear genomes of multicellular organisms. We applied two high-throughput DNA sequencing technologies to identify and characterize hundreds of spontaneously arising base-substitution mutations in 10 Caenorhabditis elegans mutation-accumulation (MA)-line nuclear genomes. C. elegans mutation rate estimates were similar to previous calculations based on smaller numbers of m…
Nature trips and traditional methods for food procurement in relation to weight status
2013
Author's version of an article in the journal: Scandinavian Journal of Public Health. Also available from the publisher at: http://dx.doi.org/10.1177/1403494812471446 Aims: The purpose of this study is to assess the relationships between trips in nature, gathering of wild plants, fishing and hunting and weight status. Methods: Data from a cross-sectional questionnaire survey of 996 parents of sixth- and seventh-graders from 38 randomly chosen schools in two Norwegian counties. All data are self-reported: Weight and height (participants were considered as overweight if BMI were 25 or higher), family trips in nature (dichotomized into ayenonce a week vs. less than once a week), gathering of w…
Effects of Positioning Aids on Understanding the Relationship Between a Mobile Map and the Environment
2013
Positioning technologies such as GPS enable mobile map applications to display a symbol representing an estimation of a user’s location on a mobile map, therefore acting as a positioning aid. Previous research on the cognitive processes involved in map reading suggests that map readers need at least two map–environment points (objects that are visualized on the map and perceived in the environment) for determining their location on a map. Hence, the positioning aid alone does not provide enough information for self-location. Using a field experiment, we assessed the effect of representing the user’s location on a map on the cognitive processes involved in self-location. The results show tha…
