Effect of wind damage on the habitat suitability of saproxylic species in a boreal forest landscape
(Springer Nature, 2018)Many forest-dwelling species are dependent on deadwood. Sources of deadwood include competition- and senescence-related mortality of trees, and various damages. This study described a methodology for predicting the effect ...Tieteelliset aikakauslehtiartikkelit

Effects of alternative electron acceptors on the activity and community structure of methane-producing and -consuming microbes in the sediments of two shallow boreal lakes
(2017)The role of anaerobic CH4 oxidation in controlling lake sediment CH4 emissions remains unclear. Therefore, we tested how relevant EAs (SO42−, NO3−, Fe3+, Mn4+, O2) affect CH4 production and oxidation in the sediments of ...info:eu-repo/semantics/article

Effects of biochar on carbon and nitrogen fluxes in boreal forest soil
(Springer Nature, 2018)Background and aims The addition of biochar to soil may offer a chance to mitigate climate change by increasing soil carbon stocks, improving soil fertility and enhancing plant growth. The impacts of biochar in cold ...Tieteelliset aikakauslehtiartikkelit

Effects of CMIP5 projections on volume growth, carbon stock and timber yield in managed scots pine, Norway Spruce and Silver Birch stands under Southern and northern boreal conditions
(MDPI AG, 2018)We investigated how recent-generation (CMIP5) global climate model projections affect the volume growth, carbon stock, timber yield and its profitability in managed Scots pine, Norway spruce and Silver birch stands on ...Tieteelliset aikakauslehtiartikkelit

Effects of errors in basal area and mean diameter on the optimality of forest management prescriptions
(Springer Science and Business Media LLC, 2021)• Key message Errors in forest stand attributes can lead to sub-optimal management prescriptions concerning the set management objectives. When the objective is net present value, errors in mean diameter result in greater ...Tieteelliset aikakauslehtiartikkelit

Effects of even-aged and uneven-aged management on carbon dynamics and timber yield in boreal Norway spruce stands: A forest ecosystem model approach
(Oxford University Press (OUP), 2019)We used a gap-type forest ecosystem model to study how even- and uneven-aged management affected the carbon dynamics and timber production in boreal Norway spruce stands. In business-as-usual management, the intensity of ...Tieteelliset aikakauslehtiartikkelit

Effects of flow gradients on directional radiation of human voice
(Acoustical Society of America (ASA), 2018)In voice communication in windy outdoor conditions, complex velocity gradients appear in the flow field around the source, the receiver, and also in the atmosphere. It is commonly known that voice emanates stronger towards ...Tieteelliset aikakauslehtiartikkelit

Effects of forest conservation and management on volume growth, harvested amount of timber, carbon stock, and amount of deadwood in Finnish boreal forests under changing climate
(Canadian Science Publishing, 2017)We employed a forest ecosystem model (SIMA) to study how the changes in forest conservation area and management affect the volume growth, harvested amount of timber, carbon stock, and amount of deadwood in Finnish boreal ...info:eu-repo/semantics/article

Effects of Gender Information in Text-Independent and Text-Dependent Speaker Verification
(Institute of Electrical and Electronics Engineers (IEEE), 2017)It is well-known that for speaker recognition task, gender-dependent acoustic modeling performs better than gender-independent modeling. The practice is to use the gender ground-truth and to train gender-dependent models. ...conferenceObject

Effects of Initial Age Structure of Managed Norway Spruce Forest Area on Net Climate Impact of Using Forest Biomass for Energy
(Springer Nature, 2017)We investigated how the initial age structure of a managed, middle boreal (62°N), Norway spruce-dominated (Picea abies L. Karst.) forest area affects the net climate impact of using forest biomass for energy. The model-based ...info:eu-repo/semantics/article
