Statistical upscaling of ecosystem CO2 fluxes across the terrestrial tundra and boreal domain: Regional patterns and uncertainties
2021
The regional variability in tundra and boreal carbon dioxide (CO2) fluxes can be high, complicating efforts to quantify sink-source patterns across the entire region. Statistical models are increasingly used to predict (i.e., upscale) CO2 fluxes across large spatial domains, but the reliability of different modeling techniques, each with different specifications and assumptions, has not been assessed in detail. Here, we compile eddy covariance and chamber measurements of annual and growing season CO2 fluxes of gross primary productivity (GPP), ecosystem respiration (ER), and net ecosystem exchange (NEE) during 1990–2015 from 148 terrestrial high-latitude (i.e., tundra and boreal) sites to a…

Updating strategies for distance based classification model with recursive least squares
2022
Abstract. The idea is to create a self-learning Minimal Learning Machine (MLM) model that is computationally efficient, easy to implement and performs with high accuracy. The study has two hypotheses. Experiment A examines the possibilities of introducing new classes with Recursive Least Squares (RLS) updates for the pre-trained self learning-MLM model. The idea of experiment B is to simulate the push broom spectral imagers working principles, update and test the model based on a stream of pixel spectrum lines on a continuous scanning process. Experiment B aims to train the model with a significantly small amount of labelled reference points and update it continuously with (RLS) to reach ma…
New national and regional biological records for Finland 9:contributions to Bryophyta and Marchantiophyta 8
2018
Five species of mosses (Bryophyta: Oncophorus demetrii, Oncophorus integerrimus, Oxyrrhynchium speciosum, Sphagnum divinum and Sphagnum medium) and one of liverworts (Marchantiophyta: Kurzia trichoclados) are presented as new for Finland. Seligeria calcarea and Seligeria pusilla, previously thought to be regionally extinct from Finland, are reported to being found again. New records in biogeographical provinces for 74 species of mosses and 36 species of liverworts are listed. Finally, 17 occurrences in provinces are removed due to misidentifications or missing specimens. nonPeerReviewed
Regional variations in occupancy frequency distributions patterns between odonate assemblages in Fennoscandia
2018
Odonate (damselfly and dragonfly) species richness and species occupancy frequency distributions (SOFD) were analysed in relation to geographical location in standing waters (lakes and ponds) in Fennoscandia, from southern Sweden to central Finland. In total, 46 dragonfly and damselfly species were recorded from 292 waterbodies. Species richness decreased to the north and increased with waterbody area in central Finland, but not in southern Finland or in Sweden. Species occupancy ranged from 1 up to 209 lakes and ponds. Over 50% of the species occurred in less than 10% of the waterbodies, although this proportion decreased to the north. In the southern lakes and ponds, none of the species o…

Osaamiskartta oppimisen ohjaamisen työvälineenä
2010
TIIVISTELMÄ Susanna Löf Osaamiskartta oppimisen ohjaamisen työvälineenä. Jyväskylä: Jyväskylän yliopisto. Opettajankoulutuslaitos. Kasvatustieteen pro gradu 2010, 85 s. Tutkimuksessa syvennyttiin osaamisen johtamiseen ja aikuisen oppimisen ohjaamiseen. Osaamisen kehittäminen ja osaamisen johtaminen ovat tämän päivän johtamisen tärkeimpiä osa-alueita. Niiden avulla organisaatiolla on mahdollisuus kehittyä ja menestyä sekä saada kilpailuetua. Osaamisen johtaminen myös motivoi ja luo työhyvinvointia henkilöstölle. Osaamisen kehittämisen välineeksi on luotu erilaisia osaamiskarttoja. Tässä tutkimuksessa tehtiin siivoustyönohjaajan osaamiskartta asiantuntijatyöryhmän avulla. Lisäksi tutkimuksen …
