Liikunnan ja oppimisen vuorovaikutusta kartoittamassa

2017

Oppiminen on laaja kokonaisuus ja liikunta tärkeä kasvuympäristön tarjoama oppimisväylä. Liikuntatutkimus on avannut uusia näkymiä liikunnan ja oppimisen yhteyksiin. Liikunnan myönteiset vaikutukset kouluarvosanoihin on havaittu erityisesti matemaattisissa aineissa. Liikunta voi myös vahvistaa lasten muistia ja toiminnanohjausta. Motoristen taitojen hallitseminen puolestaan vaikuttaa myös aivojen kehittymiseen. nonPeerReviewed

Rapid Quantification of Microalgae Growth with Hyperspectral Camera and Vegetation Indices

2021

Spectral cameras are traditionally used in remote sensing of microalgae, but increasingly also in laboratory-scale applications, to study and monitor algae biomass in cultures. Practical and cost-efficient protocols for collecting and analyzing hyperspectral data are currently needed. The purpose of this study was to test a commercial, easy-to-use hyperspectral camera to monitor the growth of different algae strains in liquid samples. Indices calculated from wavebands from transmission imaging were compared against algae abundance and wet biomass obtained from an electronic cell counter, chlorophyll a concentration, and chlorophyll fluorescence. A ratio of selected wavebands containing near…

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…

Ground-dwelling true bugs (Heteroptera) in afforested fields

2017

Former agricultural lands may host peculiar biota, because agriculture activities have changed the physical, chemical and biological features of the soil; however, biodiversity in afforested fields is poorly known. The aim of this study was to investigate the diversity of ground-dwelling true bugs (Heteroptera) in early successional afforested fields in central Finland. We used a large-scale field experiment, in which agricultural land had been afforested 25 years ago by planting monocultures of birch, pine and spruce trees. Pitfall traps caught a total of 224 heteropteran individuals representing 20 species. The community was numerically dominated by Lygaeidae, Drymus brunneus being the mo…

Dead wood and fungi : detection, diversity and conservation in boreal forests

2018

Dead wood and associated fungal communities are a crucial part of boreal forest ecosystems, and severely affected and threatened by human actions like commercial timber harvesting. Despite their importance for forest functioning, most wood-inhabiting fungal species, especially those producing small fruit bodies, are still ecologically and taxonomically poorly known. In addition, studies on dead wood profiles have neglected fine woody debris. This thesis includes detailed investigations of fruiting phenology of different morphological groups and complete dead wood profile of one semi-natural boreal forest. In addition, the diversity patterns of wood-inhabiting fungal communities according fo…

Multitaxa species richness of a wood-pasture complex in the Finnish SW-archipelago

2019

Traditional rural biotopes such as semi-natural grasslands and wood-pastures are among the most threatened biotopes in Finland. Archipelago Sea area hosts an especially representative collection of these biotopes, considering both their combined area and average quality. We surveyed birds, vascular plants, bryophytes, polypores and ground-inhabiting stipitate macrofungi in one wood-pasture complex in Korppoo, Archipelago Sea area. Here we report and discuss the results of these surveys. We detected altogether 457 species, including 8 red-listed bird species and 6 red-listed vascular plant species. We didn´t detect any red-listed bryophytes or fungi, but also these groups included several ra…

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

New national and regional biological records for Finland 11 : Contributions to Bryophyta and Marchantiophyta 10

2023

Ten species of mosses (Bryophyta: Entosthodon obtusus, Entosthodon ulvinenii, Eurhynchiastrum diversifolium, Hedwigia emodica, Hedwigia mollis, Hygrohypnum styriacum, Plagiothecium rossicum, Polytrichum perigoniale, Tortella alpicola and Ulota intermedia) are presented as new for Finland. Cephalozia lacinulata, previously considered to be regionally extinct from Finland, is reported to being found again. New records in biogeographical provinces for 67 species of mosses and 34 species of liverworts are listed. Finally, 6 occurrences in provinces are removed due to misidentifications or missing specimens. peerReviewed
