Direct and transgenerational effects of an experimental heatwave on early life stages in a freshwater snail
2019
1. Global climate change imposes a serious threat to natural populations of many species. Estimates of the effects of climate change‐mediated environmental stresses are, however, often based only on their direct effects on organisms, and neglect the potential transgenerational (e.g. maternal) effects. 2. We tested whether high temperature (i.e. an experimental heatwave), which is known to reduce the performance of adult Lymnaea stagnalis snails, affects the produced offspring (eggs and hatchlings) through maternal effects, and how strong these effects are compared with the effects of direct exposure of offspring to high temperature. We examined the effect of maternal thermal environment (15…
Consequences of single-locus and tightly linked genomic architectures for evolutionary responses to environmental change
2020
AbstractGenetic and genomic architectures of traits under selection are key factors influencing evolutionary responses. Yet, knowledge of their impacts has been limited by a widespread assumption that most traits are controlled by unlinked polygenic architectures. Recent advances in genome sequencing and eco-evolutionary modelling are unlocking the potential for integrating genomic information into predictions of population responses to environmental change. Using eco-evolutionary simulations, we demonstrate that hypothetical single-locus control of a life history trait produces highly variable and unpredictable harvesting-induced evolution relative to the classically applied multi-locus mo…
Biofiltration of airborne VOCs with green wall systems : microbial and chemical dynamics
2018
Botanical air filtration is a promising technology for reducing indoor air contaminants, but the underlying mechanisms need better understanding. Here, we made a set of chamber fumigation experiments of up to 16 weeks of duration, to study the filtration efficiencies for seven volatile organic compounds (VOCs; decane, toluene, 2-ethylhexanol, α-pinene, octane, benzene, and xylene) and to monitor microbial dynamics in simulated green wall systems. Biofiltration functioned on sub-ppm VOC levels without concentration-dependence. Airflow through the growth medium was needed for efficient removal of chemically diverse VOCs, and the use of optimized commercial growth medium further improved the e…
The clinical impact of PCR‐based point‐of‐care diagnostic in respiratory tract infections in children
2020
Abstract Background Children are commonly affected by respiratory tract infections. Based on clinical symptoms, laboratory evaluation, and imaging, the causative pathogen often cannot be delineated. Point‐of‐care‐testing systems that provide an opportunity for fast detection of common viruses and some bacteria can therefore influence treatment's options. We aimed to examine whether the Biofire® FilmArray® has an effect on antibiotic treatment, duration of antibiotic therapy, and length of hospital stay within a pediatric cohort. Methods We included children who were admitted to inpatient treatment with an acute respiratory tract infection from 02/2017 to 04/2018 using the FA respiratory pan…
Tiedonarkeologisia pohdintoja Viipurin vuoden 1918 haudatuista muistoista
2021
The subject of the article is the ‘memory war’ over the memory of the Civil War of 1918 in Vyborg, and the displaced Karelians’ experience in the time of diaspora. Until the wars of 1939–1945 the culture of remembrance of the Civil War was divided in Vyborg and in Finland and many truths of the war were maintained in the Red’s and White’s own groups. The article details how the dichotomous history culture of Civil War memories has slowly transformed into a diversified and critical analysis over the past one hundred years. The qualitative material used in the article consists of memory data written by displaced Karelians held in Finnish archives. The article is a knowledge-archaeological ana…

"Lehtemme on puolueeton, eikä harrasta politiikkaa" : suomalaisten puolueiden ja niiden poliitikkojen käsittely Uusi Maailma -lehdessä 1963-1979
2017
1960- ja 1970-luku olivat aikakauslehtimarkkinoilla kovan kilpailun aikaa. Ilmari Turjan luotsaama Uusi Kuvalehti oli joutunut taloudellisiin vaikeuksiin sillä seurauksella, että se myytiin Uuden Suomen lehtitalolle 1960-luvun alussa. Lehtitalo päätti ratkaista omistansa Naisten Maailma –lehden menekkiin liittyvät ongelmat yhdistämällä sen hankkimansa Uuden Kuvalehden kanssa. Seurauksena vuonna 1963 syntyi kokonaan uudenlainen aikakauslehti, joka nimettiin Uudeksi Maailmaksi. Monipuolisten sisältöjen avulla se pyrki houkuttelemaan lukijoita erilaisista viiteryhmistä. Lehti pyrki sopeutumaan alusta alkaen ajan politisoituneeseen ilmapiiriin. Ensimmäisessä numerossa päätoimittaja Jussi Talvi …
