A Combined Field and Laboratory Study on Activated Carbon-Based Thin Layer Capping in a PCB-Contaminated Boreal Lake
Abel, S; Akkanen, J (American Chemical Society (ACS), 2018)The in situ remediation of aquatic sediments with activated carbon (AC)-based thin layer capping is a promising alternative to traditional methods, such as sediment dredging. Applying a strong sorbent like AC directly to ...Tieteelliset aikakauslehtiartikkelit

Biochar as a tool to reduce the agricultural greenhouse-gas burden - knowns, unknowns and future research needs
Kammann C; Ippolito JA; Hagemann N; Borchard N; Cayuela M; Estavillo JM; Fuertes-Mendizabal T; Jeffery S; Kern J; Novak J; Rasse D; Saarnio S; Schmidt H-P; Spokas K; Wrage-Mönnig N (Vilnius Gediminas Technical University, 2017)Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) and methane (CH4). Since human nutritional and bioenergy needs continue to increase, ...info:eu-repo/semantics/article

Bracketing phenogenotypic limits of mammalian hybridization
Savriama, Y; Valtonen, M; Kammonen, JI; Rastas, P; Smolander, OP; Lyyski, A; Häkkinen, TJ; Corfe, IJ; Gerber, S; Salazar-Ciudad, I; Paulin, L; Holm, L; Löytynoja, A; Auvinen, P; Jernvall, J (The Royal Society, 2018)An increasing number of mammalian species have been shown to have a history of hybridization and introgression based on genetic analyses. Only relatively few fossils, however, preserve genetic material, and morphology must ...Tieteelliset aikakauslehtiartikkelit

Ethnobotanical survey of plants used as repellents against housefly, Musca domestica L. (Diptera: Muscidae) in Budondo Subcounty, Jinja District, Uganda
Baana, Kalori; Angwech, Harriet; Malinga, Geoffrey Maxwell (Springer Nature, 2018)Background The housefly, Musca domestica L., is a major public health and domestic pest that spoils food and causes irritation and is a vector of many infectious disease pathogens of medical and veterinary importance. ...Tieteelliset aikakauslehtiartikkelit

Evaluation of the confusion matrix method in the validation of an automated system for measuring feeding behaviour of cattle
Ruuska, Salla; Hämäläinen, Wilhelmiina; Kajava, Sari; Mughal, Mikaela; Matilainen, Pekka; Mononen, Jaakko (Elsevier BV, 2018)The aim of the present study was to evaluate empirically confusion matrices in device validation. We compared the confusion matrix method to linear regression and error indices in the validation of a device measuring feeding ...Tieteelliset aikakauslehtiartikkelit

Genotype- and provenance-related variation in the leaf surface secondary metabolites of silver birch
Deepak, Maya; Lihavainen, Jenna; Keski-Saari, Sarita; Kontunen-Soppela, Sari; Salojärvi, Jarkko; Tenkanen, Antti; Heimonen, Kaisa; Oksanen, Elina; Keinänen, Markku (Canadian Science Publishing, 2018)The cuticular wax layer on silver birch (Betula pendula Roth) leaves is rich in cyclic secondary metabolites that provide defense against various environmental factors. Micropropagated trees from the southern (60°N), central ...Tieteelliset aikakauslehtiartikkelit

Lake zooplankton delta13C values are strongly correlated with the delta13C values of distinct phytoplankton taxa
Taipale S; Vuorio K; Brett MT; Peltomaa E; Hiltunen M; Kankaala P (Ecological Society of America, 2016)Analyses of carbon stable isotopes are often used to estimate the contributions of allochthonous and autochthonous dietary resources to aquatic consumers. Most pelagic food web studies assume that all phytoplankton taxa ...info:eu-repo/semantics/article

Long-term effects of land use on perinatal mortality in the Endangered Saimaa ringed seal population
Liukkonen Lauri; Rautio Anni; Sipilä Tero; Niemi Marja; Auttila Miina; Koskela Jouni; Kunnasranta Mervi (Inter-Research Science Center, 2017)Human disturbance can affect the viability of wildlife populations partly through its effects on breeding success. Land use as a form of disturbance may do so by fragmenting the key environments of certain species. We used ...info:eu-repo/semantics/article

Narrow-clawed crayfish in Finland: Aphanomyces astaci resistance and genetic relationship to other selected European and Asian populations
Jussila, Japo; Maguire, Ivana; Kokko, Harri; Tiitinen, Vesa; Makkonen, Jenny (EDP Sciences, 2020)The narrow-clawed crayfish (Pontastacus leptodactylus) is an alien species in Finland with only a few populations reported from the southeastern region during the last century. We discovered a productive population in the ...Tieteelliset aikakauslehtiartikkelit

Reproductive decisions of boreal three-toed woodpeckers (Picoides tridactylus) in a warming world: from local responses to global population dynamics
Fayt, Philippe (Finnish Zoological and Botanical Publishing Board, 2006)Here, I examine whether both nestling prey abundance and profitability affect the timing of reproduction and hence the number of fledglings of three-toed woodpeck-ers, Picoides tridactylus. Individuals living ...article

RPA-PCR couple: an approach to expedite plant diagnostics and overcome PCR inhibitors
Munawar, MA; Martin, F; Toljamo, A; Kokko, H; Oksanen, E (Future Science Ltd, 2020)DNA extraction can be lengthy and sometimes ends up with amplification inhibitors. We present the potential of recombinase polymerase amplification (RPA) to replace plant DNA extraction. In our rapid ‘RPA-PCR couple’ ...Tieteelliset aikakauslehtiartikkelit
