Labile nitrogen, carbon, and phosphorus pools and nitrogen mineralization and immobilization rates at low temperatures in seasonally snow-covered soi…
2006
Surface mineral horizons from four ecosystems sampled in the northwestern Italian Alps were incubated at −3 and +3°C to simulate subnivial and early thaw period temperatures for a seasonally snow-covered area. The soil profiles at these sites represent extreme examples of management, grazed meadow (site M) and extensive grazing beneath larch (site L) or naturally disturbed by avalanche and colonized by alder (site A) and the expected forest climax vegetation beneath fir (site F). Changes in labile pools of nitrogen (N) and phosphorus (P) were active at all sites at both temperatures during 14 days of laboratory incubation. Ammonium was the dominant inorganic form of total dissolved N (TDN),…
Social Acceptance of Climate Change Adaptation in Farms and Food Enterprises : a Case Study in Finland
2015
This article identifies perceived climate change risks and adaptation aspects among farms and food processing enterprises using a case study in Finland. In addition, the article pinpoints key factors that contribute to the social acceptance of climate change adaptation and mitigation policies in the food system. The purpose is to study the willingness of farms and food enterprises to accept and adapt to different climate policy implementation. The research data consists of 27 thematic interviews conducted in 2012 and 2013. The main research questions were: 1. What risks does climate change pose to farms and food enterprises? 2. What adaptation features can be identified in farms and food en…
Reciprocal Relationships Between Perceived Supportive School Climate and Self-reported Truancy : A Longitudinal Study from Grade 6 to Grade 9
2022
This longitudinal study of 1,066 Finnish students examined bidirectional reciprocal relationships between changes in perceived supportive school climate and changes in self-reported truancy from the last year of primary school (Grade 6) to the last year of lower secondary school (Grade 9). The results of the random intercept cross-lagged panel model showed, first, that a decrease in positive perceptions of school climate at the previous time point predicted more self-reported truancy at the following time point. Second, an increase in self-reported truancy predicted less positive perceptions of supportive school climate. The study indicates that students’ perceptions of supportive school cl…
The Development of Teachers' and Their Students' Social and Emotional Learning During the “Learning to Be Project”-Training Course in Five European C…

This study was funded by a project Learning to Be: Development of Practices and Methodologies for Assessing Social, Emotional and Health Skills within Education Systems (#4120034) in the framework of Erasmus+ KA3 program (582955-EPP-1-2016-2-LT-EPPKA3-PI-POLICY). We are also grateful for funding by the Academy of Finland (#308352) and Finnish Strategic Research Council (#327242).
Koulun yhteisöllinen ilmapiiri ja oppilaiden yhteiskunnallisen vaikuttamisen orientaatio : yhteyksiä etsimässä
2021
Aikaisemmat tutkimukset viittaavat siihen, että koulun yhteisöllisellä ilmapiirillä on yhteys oppilaiden yhteiskunnallisen vaikuttamisen orientaatioon. Eräiltä osin tuo yhteys on kuitenkin kyseenalaistettu. tässä artikkelissa puretaan kysymys osiin ja tutkitaan, millainen yhteys oppilaiden ja opettajien kokemuksilla koulun ilmapiirin yhteisöllisyyden osatekijöistä on oppilaiden yhteiskunnallisen vaikuttamisen orientaatioon. Tutkimusaineistona käytettiin kansainvälisen ICCS 2016 -tutkimuksen Suomesta kerättyjä opettaja- ja oppilaskyselyaineistoja. Perinteisten kuvailevien tilastollisten menetelmien lisäksi aineiston analysoinnissa sovellettiin monitasomallinnusta. Tulosten perusteella oppila…
Database Species-Area Relationships in Palaearctic Grasslands
2012
The Database Species-Area Relationships in Palaearctic Grasslands (GIVD ID EU-00-003) is an initiative of the European Dry Grassland Group (EDGG) and primarily functions as repository for all data sampled during the EDGG Research Expeditions. During these expeditions two types of highly standardised sampling of dry grassland vegetation in the Palaearctic realm are carried out: (i) nested-plot sampling on squares of 0.0001, 0.001, 0.01, 0.1, 1, 10, and 100 m2; (ii) additional normal releves of 10-m2 plots. For all plot sizes, the terricolous vascular plants, bryophytes, and lichens are recorded that are superficially present (shoot presence). Additionally, for all 10-m2 plots species cover i…
Soil forming factors
2007
The Russian geologist Vasily Dokuchaev (1846–1903), considered the father of soil science, was the first to identify and discuss, at the end of 19th century, what we know today as the “factors of soil formation”. He introduced the idea that soil is not something inert and stable, but it develops and evolves under the influence of climatic agents and vegetation that operate over time on a given geological substrate
On-Orbit Degradation of Solar Instruments
2013
International audience; We present the lessons learned about the degradation observed in several space solar missions, based on contributions at the Workshop about On-Orbit Degradation of Solar and Space Weather Instruments that took place at the Solar Terrestrial Centre of Excellence (Royal Observatory of Belgium) in Brussels on 3 May 2012. The aim of this workshop was to open discussions related to the degradation observed in Sun-observing instruments exposed to the effects of the space environment. This article summarizes the various lessons learned and offers recommendations to reduce or correct expected degradation with the goal of increasing the useful lifespan of future and ongoing s…
The adaptations to tube-dwelling life of Propsilocerus akamusi (Diptera: Chironomidae) larvae and its eutrophication-tolerant mechanisms
2019
Propsilocerus akamusi (Diptera: Chironomidae) is a dominant macroinvertebrate species in many eutrophic lakes in subtropical and temperate zones. P. akamusi larvae can migrate deep into the sediment (>30 cm) during summer where is no oxygen. However, to our knowledge, the specific adaptive tactics of its tube-dwelling life (>30 cm) and underlying mechanisms why this species is favored by nutrient-rich lakes remain limited. With the understanding above-mentioned issues, we can provide important information for the development of sensitive biomonitoring. We examined monthly morphological dynamics and physiological adaptations of P. akamusi to anoxic conditions, and environmental relationships…
Potential for adaptation to climate change: family-level variation in fitness-related traits and their responses to heat waves in a snail population.
2017
Background On-going global climate change poses a serious threat for natural populations unless they are able to evolutionarily adapt to changing environmental conditions (e.g. increasing average temperatures, occurrence of extreme weather events). A prerequisite for evolutionary change is within-population heritable genetic variation in traits subject to selection. In relation to climate change, mainly phenological traits as well as heat and desiccation resistance have been examined for such variation. Therefore, it is important to investigate adaptive potential under climate change conditions across a broader range of traits. This is especially true for life-history traits and defences ag…
