Ravinnetason ja ojituksen vaikutus suokasvillisuuden monimuotoisuuteen ja lajikoostumukseen
2013
Lajistollisessa monimuotoisuudessa on havaittavissa ajallista ja paikallista vaihtelua, joka on jo vuosisatojen ajan innoittanut ekologeja selvittämään lajirikkauden määrittäviä tekijöitä. Muun muassa pinta-alan, elinympäristön heterogeenisyyden, energian ja resurssien saatavuuden sekä erilaisten häiriöiden on havaittu vaikuttavan lajistolliseen monimuotoisuuteen. Osa monimuotoisuuteen vaikuttavista prosesseista on yhä huonosti tunnettuja, ja yksittäisen tekijän vaikutusta voi olla vaikea tulkita, sillä eri tekijät ovat keskenään vuorovaikutuksessa. Tämän tutkimuksen tavoitteena oli selvittää suokasvillisuusyhteisöjen avulla, vaikuttavatko resurssit tai häiriö (1) yhteisön lajimäärään (alfa…
La genètica de les migracions humanes: Seguint el rastre de les migracions a través del nostre genoma
2014
La reconstruccio de les migracions humanes es possible gracies a la informacio aportada per diverses disciplines. L’estudi de la diversitat genetica de les poblacions humanes actuals ens revela quins han estat els esdeveniments demografics i moviments migratoris passats que han deixat una empremta en el nostre genoma. El coneixement dels moviments migratoris en temps prehistorics ens permet comprovar hipotesis proposades des d’altres disciplines cientifiques. De la mateixa manera, la distribucio de la diversitat genetica en el futur dependra, en gran part, de les intenses migracions humanes actuals facilitades pels avencos tecnologics.
Koulutuksen tasa-arvon muuttuvat merkitykset: Kasvatussosiologian vuosikirja 1
2016
Koulutuskysymysten ymmärtäminen edellyttää yhteiskuntatieteellistä ymmärrystä, kun koulutus kytkeytyy yhä tiiviimmin talouteen, elinkeino- ja työvoimapolitiikkaan sekä väestöjen ja osaamisen hallintaan. Kasvatus- ja koulutussosiologinen tutkimus on Suomessa vahvistunut 1980-luvulta lähtien merkittävästi. Kasvatussosiologiselle ymmärrykselle on tilausta, joskin koulutuspolitiikkaa tehdään paljolti tutkimustuloksista piittaamatta, mikä sekin on sosiologisesti kiinnostava ja yhteiskuntatieteellistä analyysia kaipaava asia! Sosiologisen koulutustutkimuksen vahvistuminen näkyy hyvin kotimaisten tieteellisten konferenssien esitelmätarjonnassa. Suomessa järjestetään vuosittain useita tieteellisiä …
“DIVERSETHEATRE”: STAGE FICTION AS SPECIAL EDUCATIONAL PRACTICE
2014
In our heterogeneous society diversity has become a focus of debate in the wide context of “diverse dimensions” such as ethnicity, language & culture, gender but also handicap and disability. The EU Research and Innovation program Horizons 2020 has therefore pinpointed the urgency to be explicit about what one means when using the term “inclusion” and most of all, about the practical use of this concept in the direction of sustainable growth, high quality of research and human life. In this view, Special Education has always been committed to the enquiry on educability in diversity, aiming at the socialization of special needs in order to promote individuals’ full integration and inclus…
Dynamique de la communauté microbienne de sols tropicaux suite à une application répétée de fertilisants organiques et minéraux
2019
Organic waste products (OWP) with NPK mineral fertilization are known to have an impact on soil microbial communities. However, dynamic of these communities following a repeated OWP and NPK application has not been well described. In the present study, this dynamic was observed on soil sampled at the La Mare (La Réunion) field experiment, which was set up in 2013. This experiment includes control plot (without organic input, but mineral fertilization) and several plots receiving different types of OWP coupled with NPK fertilization. Physico-chemical parameters were measured on soils and OWPs (2013 to 2017). Soil microbial biomass (from 2013 to 2018) and the structure of microbial community …
Didáctica (lengua y literatura)
2017
El aumento del racismo y la xenofobia en las sociedades europeas y el hecho de que los marroquíes, en particular, constituyan el colectivo inmigrante más rechazado por los españoles motiva la propuesta de club de lectura a partir de dos obras de LIJ (literatura infantil y juvenil) de autoras transculturales, en el marco de la educación literaria e intercultural, que presentamos en este artículo y que proponemos evaluar a través de un cuestionario pretest-postest, empleando un diseño de investigación cuasi-experimental. Con esta perseguimos que el alumnado de Secundaria al que se dirige tenga ocasión de: (1) incrementar sus conocimientos sobre la cultura árabe, (2) reflexionar sobre el desar…
CoproID predicts the source of coprolites and paleofeces using microbiome composition and host DNA content
2020
Shotgun metagenomics applied to archaeological feces (paleofeces) can bring new insights into the composition and functions of human and animal gut microbiota from the past. However, paleofeces often undergo physical distortions in archaeological sediments, making their source species difficult to identify on the basis of fecal morphology or microscopic features alone. Here we present a reproducible and scalable pipeline using both host and microbial DNA to infer the host source of fecal material. We apply this pipeline to newly sequenced archaeological specimens and show that we are able to distinguish morphologically similar human and canine paleofeces, as well as non-fecal sediments, fro…
Tale(s) of a forest – re-creation of a primeval forest in three environmental narratives
2020
We analyze three environmentally conscious works that are concerned with the state of Finnish forests: the documentary film Metsän tarina/Tale of a Forest (2012), the book with the same name (2013) and the series of short documentaries Tarinoita metsästä/Tales from the Forest (2013). By combining methods from arts research and ecology, we ask how the narratives adapt material from nature photography. The film and book present mythic stories and old Finnish beliefs about forests. They also contain references to cultural memory. Additionally, the biodiversity on display reflects a conventional practice to exhibit large or charismatic species. However, the ecological message remains only impli…
Moderating cultural effects in a higher e-education context? Supervisor's tone of voice in recorded audio feedback
2017
Providing feedback to learners on their writing assignments is one of the most important and time-consuming tasks that a supervisor performs. In e-Education environments, especially in the case of distance learning, giving feedback becomes more challenging because there are often no opportunities for face-to-face interaction. Typically, a supervisor provides comments to learners in written form via email; however, the use of recorded audio feedback (RAF) in e-Education environments has become a viable alternative. This work in progress reports on learners’ perceptions of RAF in a multi-cultural higher eEducation context. Our observations indicate that learners tend to have positive feelings…
Analysing gene flow in heterogeneous landscapes: why and how to use genetic graphs?
2019
International audience; In heterogeneous landscapes, when species occupy discrete habitat patches, ecological connectivity is influenced by populations’ topology. Graph-theoretic methods constitute a relevant tool to reveal this topology and better analyse gene flow. Despite growing interest in genetic graphs, a better understanding of when and how to use them is lacking.To fill this gap, we simulated gene flow between 50 populations in different landscape configurations and constructed genetic graphs using various genetic distances and pruning (link selection) methods. We then compared metrics derived from these graphs to analogous metrics describing the topology and connectivity of the di…
