Increasing human environmental footprint does not lead to biotic homogenization of forest bird communities in northern USA
2023
Studies have shown negative impacts of increased human pressures on biodiversity at local (alpha-diversity) and regional (gamma-diversity) scales. However, the diversity between local sites (beta-diversity) has received less attention. This is an important shortcoming since beta- diversity acts as a linkage between the local and regional scales. Decreased beta- diversity means that local sites lose their distinctiveness, becoming more similar to each other. This process is known as biotic homogenization. However, the mechanisms causing biotic homogenization have not been fully studied nor its impacts on different facets of biodiversity. We examined if land- use change due to human actions c…
A synthesis of multi-taxa management experiments to guide forest biodiversity conservation in Europe
2023
Most European forests are used for timber production. Given the limited extent of unmanaged (and especially primary) forests, it is essential to include commercial forests in the conservation of forest biodiversity. In order to develop ecologically sustainable forest management practices, it is important to understand the management impacts on forest-dwelling organisms. Experiments allow testing the effects of alternative management strategies, and monitoring of multiple taxa informs us on the response range across forest-dwelling organisms. To provide a representative picture of the currently available information, metadata on 28 multi-taxa forest management experiments were collected from…

Contemporary spatial and environmental factors determine vascular plant species richness on highly fragmented meadows in Central Finland
2018
Context Habitat loss is a major threat to biodiversity. It can create temporal lags in decline of species in relation to destruction of habitat coverage. Plant species specialized in semi-natural grasslands, especially meadows, often express such extinction debt. Objectives We studied habitat loss and fragmentation of meadows and examined whether the changes in meadow coverage had caused an extinction debt on vascular plants. We also studied whether historical or present landscape patterns or contemporary environmental factors were more important determinants of species occurrence. Methods We surveyed the plant species assemblages of 12 grazed and 12 mown meadows in Central Finland and dete…
Environmental mitigation hierarchy and biodiversity offsets revisited through habitat connectivity modelling.
2020
International audience; Biodiversity loss is accelerating because of unceasing human activity and land clearing for development projects (urbanisation, transport infrastructure, mining and quarrying …). Environmental policy-makers and managers in different countries worldwide have proposed the mitigation hierarchy to ensure the goal of “no net loss (NNL) of biodiversity” and have included this principle in environmental impact assessment processes. However, spatial configuration is hardly ever taken into account in the mitigation hierarchy even though it would greatly benefit from recent developments in habitat connectivity modelling incorporating landscape graphs. Meanwhile, national, Euro…
“Face the cow”: reconnecting to nature and increasing capacities for pro-environmental agency
2020
Arts-based practices can support sustainability, combined with research that points out needs for intervention. We practiced environmental sensitivity and dialogic art with fifth-grade school pupils as part of an International Socially Engaged Art Symposium (ISEAS2019). Using arts-based action research methodology, our case study focused on the opportunities of arts-based environmental education in advancing the management of meadows and wood-pastures. We explored nature connectedness and pro-environmental mindsets and behaviors among the pupils and artists/researchers. The artistic results encompassed the dialogic interactions of the intervention, exhibited artworks, and audiovisual docume…
”Kissankieliset” japania oppimassa
2017
Viime vuoden elokuussa voimaan astuneeseen uuteen lukion opetussuunnitelmaan on vieraiden kielten osioon sisällytetty kuvaus Aasian ja Afrikan kielistä B3-kielenä. Kuvaus on laadittu japaniin ja mandariinikiinaan ja on sovellettavissa myöhemmin myös muihin Euroopan ulkopuolisiin kieliin. Vaikka japani joutui odottamaan statuksensa ”virallistamista” koulukielenä varsin pitkään, on sitä opiskeltu maassamme vilkkaasti vuosikausia eikä innossa näy hiipumisen merkkejä. Niin Suomi kuin Japanikin monikulttuuristuvat ja -kielistyvät ja kiinnostus Japaniin Suomessa ja Suomeen Japanissa on jatkuvaa. Suomenkieliset saavat apua japanin opiskeluun kielten monista samankaltaisista piirteistä. nonPeerRevi…
Environmental context determines pollution impacts on ecosystem functioning
2023
Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides and industrial chemicals in the environment. Part of the problem reflects the multifarious origins of these micropollutants, which can derive from urban and agricultural sources. Understanding how micropollutants harm ecosystems is a major scientific challenge due to asymmetries of stress across trophic levels and ecological surprises generated by multiple drivers interacting in human-impacted landscapes. We used field assays above and below municipal wastewater treatment plants (WWTPs) in 60 sampling locations across 20 Swiss streams to test how micropoll…
Luokanopettajaopiskelijoiden lajintuntemustaidot sekä asenteet ja valmiudet opettaa lajintuntemusta
2016
Varsinaisena luonnontieteenä biologian ymmärtämisen keskiössä on lajien tuntemus, sillä se avaa ovia lukuisille biologian keskeisille osa-alueille, kuten ekologiaan ja evoluutiobiologiaan. Lajien tuntemus auttaa ymmärtämään biodiversiteetin eli luonnon monimuotoisuuden eri puolia, lajien evolutiivista historiaa ja kehitystä, ja ennen kaikkea kestävän kehityksen periaatteita ja tavoitteita säilyttää luonto ennallaan tuleville sukupolville. Lajintuntemuksessa on kyse paitsi yleissivistyksestä, myös yhteydestä luontoon ja luonnon monimuotoisuuden arvostuksesta. Tämän tutkimuksen tavoitteena oli tutkia Jyväskylän yliopiston Opettajankoulutuslaitoksen luokanopettajaopiskelijoiden lajintuntemusta…
Interdisciplinary Perspectives on Planetary Well-Being
2024
This book proposes a paradigm shift in how human and nonhuman well-being are perceived and approached. In response to years of accelerated decline in the health of ecosystems and their inhabitants, this edited collection presents planetary well-being as a new cross-disciplinary concept to foster global transformation towards a more equal and inclusive framing of well-being. Throughout this edited volume, researchers across the humanities, social sciences, and natural sciences apply and reflect on the concept of planetary well-being, showcasing its value as an interdisciplinary, cross-sectoral changemaker. The book explores the significance of planetary well-being as a theoretical and empiri…
