Gene flow from an adaptively divergent source causes rescue through genetic and demographic factors in two wild populations of Trinidadian guppies

2016

Genetic rescue, an increase in population growth owing to the infusion of new alleles, can aid the persistence of small populations, but its use as a management tool is limited by a lack of empirical data geared towards predicting effects of gene flow on local adaptation and demography. Experimental translocations provide an ideal opportunity to monitor the demographic consequences of gene flow. In this study we take advantage of two experimental introductions of Trinidadian guppies to test the effects of gene flow on downstream native populations. We individually marked guppies from the native populations to monitor population dynamics for 3 months before and 26 months after gene flow. We …

Newly Digitized Database Reveals the Lives and Families of Forced Migrants from Finnish Karelia

2017

Studies on displaced persons often suffer from a lack of data on the long-term effects of forced migration. A register created during 1960s and published as a book series ‘Siirtokarjalaisten tie’ in 1970 documented the lives of individuals who fled the southern Karelian district of Finland after its first and second occupation by the Soviet Union in 1940 and 1944. To realize the potential value of these data for scientific research, we have recently scanned the register using optical character recognition (OCR) software, and developed proprietary computer code to extract these data. Here we outline the steps involved in the digitization process, and present an overview of the Migration Kare…

Education Leads to a More Physically Active Lifestyle : Evidence Based on Mendelian Randomization

2019

Physical inactivity is a major health risk worldwide. Observational studies suggest that higher education is positively related to physical activity, but it is not clear whether this relationship constitutes a causal effect. Using participants (N = 1651) drawn from the Cardiovascular Risk in Young Finns Study linked to nationwide administrative data from Statistics Finland, this study examined whether educational attainment, measured by years of education, is related to adulthood physical activity in terms of overall physical activity, weekly hours of intensive activity, total steps per day, and aerobic steps per day. We employed ordinary least squares (OLS) models and extended the analysis…

Rising rural body-mass index is the main driver of the global obesity epidemic in adults.

2019

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017—and more than 80% in some low- and middle-income regions—w…

Children’s Disclosures of Physical Abuse in a Population-Based Sample

2020

Few studies have explored the disclosure of child physical abuse although child sexual abuse disclosure has been widely studied and debated for years. The present study explores the characteristics of child physical abuse disclosures and compares them to previously published findings on child sexual abuse disclosure from the same data. The data consist of a representative sample of 11,364 sixth and ninth graders. Participants responded to a wide variety of questions concerning experiences of violence, including child physical abuse and child sexual abuse, in the Finnish Child Victim Survey conducted in 2013. Within this sample, the prevalence of child physical abuse was 4.1%. Children repo…

Association between arterial stiffness and walking capacity in older adults

2022

Background and aim: Arterial stiffening – a process that is largely due to intimal thickening, collagen disposition or elastin fragmentation – significantly contributes to cardiovascular events and mortality. There is also some evidence that it may negatively affect physical function. This study aimed to evaluate whether arterial stiffness was associated with measures of walking capacity in a large, population-based sample of highly aged older adults.Methods: A population-based sample of 910 community-dwelling adults (aged 75, 80, or 85 years) were investigated in a cross-sectional observational study. Pulse wave velocity (PWV), a surrogate marker of arterial stiffness, was estimated based …

‘Where the F… is Vuotso?’ : heritage of Second World War forced movement and destruction in a Sámi reindeer herding community in Finnish Lapland

2017

In this paper we discuss the heritage of the WWII evacuation and the so-called ‘burning of Lapland’ within a Sámi reindeer herding community, and assess how these wartime experiences have moulded, and continue to mould, the ways people memorialise and engage with the WWII material remains. Our focus is on the village of Vuotso, which is home to the southernmost Sámi community in Finland. The Nazi German troops established a large military base there in 1941, and the Germans and the villagers lived as close neighbours for several years. In 1944 the villagers were evacuated before the outbreak of the Finno-German ‘Lapland War’ of 1944–1945, in which the German troops annihilated their militar…

Harrastuneisuuden yhteys elämänlaatuun yksin tai toisen kanssa asuvilla iäkkäillä henkilöillä

2017

Harrastus on töistä ja muista päivittäisistä toiminnoista erillään oleva aktiviteetti, johon yksilöt osallistuvat saadakseen nautintoa tai hyvinvointia. Elämänlaatu viittaa yksilöiden yleiseen hyvinvointiin ja se sisältää muun muassa terveyden, koulutuksen sekä sosiaalisen osallisuuden. Yksin asuminen on yhä yleisempää myös Suomessa ja sen on havaittu olevan yhteydessä matalampaan hyvinvointiin ja elämänlaatuun. Harrastuneisuuden on havaittu olevan yhteydessä parempaan elämänlaatuun, mutta asiaa ei ole tarkasteltu yksin asuvien ja toisen kanssa asuvien vanhusten kesken. Tutkimuksen tarkoituksena oli selvittää, onko ko-tona tai kodin ulkopuolella tapahtuva harrastuneisuus yhteydessä parempaa…
