Created substrates do not fully mimic natural substrates in restoration: the occurrence of polypores on spruce logs
2014
Many protected areas have been under intensive forest management prior to protection and thus lack natural ecosystem structures and dynamics. Dead wood is a key structure in forests harboring hundreds of threatened species. We investigated the ecological success of dead wood creation as a boreal forest restoration measure. We analysed whether the polypore communities of chain-saw felled and girdled (subsequently fallen) Norway spruce ( (L.) H. Karst.) logs differ from naturally formed spruce logs of similar decay stage and size. The study was conducted in Leivonmäki National Park in central Finland 8 years after the restoration measures. The average number of polypore species was highest o…
Ecology, environmental requirements and conservation of corticioid fungi occupying small diameter dead wood
2016
The increasing human impact upon the biosphere of earth is causing profound changes across all spatial scales. The ability to cope with human-induced disturbance varies among organisms; specialist species are more negatively affected than generalist species. Forests are among the most heavily affected ecosystems; especially the dead wood associated organisms are in peril. The earlier research has strongly focused on large diameter dead wood and associated species. The aim of this thesis was to investigate small diameter dead wood and collect systematic information about species richness and abundance as well as habitat and substrate preferences of associated corticioid fungi. Fungal data wa…

Long-term impacts of increased timber harvests on ecosystem services and biodiversity : A scenario study based on national forest inventory data
2020
The transition to a climate-neutral economy is expected to increase future timber demands and endanger the multifunctionality of forests. National scenario analyses are needed to determine long-term forest management impacts and support forest policy making in defining guidelines for the sustainable provision of forests’ ecosystem services and biodiversity (ESB). Using national forestry inventory data, the forest management model MASSIMO and a model to estimate harvesting costs, we simulated forest development in Switzerland under five politically relevant timber harvesting scenarios until 2106 (business as usual and four increased timber mobilisation scenarios). Model results were analysed…

The effect of grazing history on fungal diversity in broadleaved wood pastures
2012
Traditional rural biotopes such as wood pastures are species rich habitats which have been created by extensive agriculture. In all European countries both the quality and quantity of traditional rural biotopes have drastically decreased during the past century because of increasing farming intensity. This decline is causing a threat to many species, but very little is known about the conservation ecology of fungi living in wood pastures. Considering vascular plants, it is known that sites with long management history have higher species richness compared to abandoned sites. It is also known that species richness is highest with intermediate grazing intensity. In this study I investigated i…
Tale(s) of a forest – re-creation of a primeval forest in three environmental narratives
2020
We analyze three environmentally conscious works that are concerned with the state of Finnish forests: the documentary film Metsän tarina/Tale of a Forest (2012), the book with the same name (2013) and the series of short documentaries Tarinoita metsästä/Tales from the Forest (2013). By combining methods from arts research and ecology, we ask how the narratives adapt material from nature photography. The film and book present mythic stories and old Finnish beliefs about forests. They also contain references to cultural memory. Additionally, the biodiversity on display reflects a conventional practice to exhibit large or charismatic species. However, the ecological message remains only impli…
Kokneses novada autoru dzejas iepazīšana 11. klasē
2018
Diplomdarba „Kokneses novada autoru dzejas iepazīšana 11. klasē” mērķis ir izstrādāt metodiskās sistēmas variantu, kas, iepazīstot sava novada dzejniekus un viņu daiļradi, modinātu skolēnu interesi par sava novada dzejniekiem un viņu radošo darbību. Diplomdarbam ir ievads, piecas nodaļas ar apakšnodaļām, kā arī secinājumi un 21 pielikums. Pirmajā nodaļā ir teorētiski pamatoti diplomandes uzskati par dzejas apguves nozīmību literatūras mācību procesā. Otrā nodaļa ir veltīta Kokneses novada dzejnieku personības un daiļrades iepazīšanai un izpētei. Trešajā nodaļā ir aprakstīta skolotājas sagatavošanās mācību stundām, darbam klasē, pētītas jauniešu vecumposma īpatnības un raksturoti pētījumā ie…
Senās DNS analīžu pielietojums Latvijas teritorijas dzelzs laikmeta apbedījumu raksturojumā
2022
Darba mērķis: analizēt Latvijas teritorijā iegūto arheoloģisko osteoloģisko materiālu, veicot senās DNS analīzi, lai novērtētu endogēnās DNS saglabātības pakāpi un paplašinātu esošās zināšanas par Daugavas un Mēmeles krastus apdzīvojušo iedzīvotāju ģenētisko izcelsmi. Tika veikta mtDNS haplogrupu sastopamības izpēte senās DNS paraugiem, gan izmantojot publicētus rezultātus, gan veicot senās DNS analīzi dzelzs laikmeta paraugiem. Dzelzs laikmetā Latvijas teritorijā konstatējamas jaunas mtDNS haplogrupas, kas sakrīt ar līdzīgi datētām arī citur Baltijas jūras reģionā. Pētījumā izmantotās metodes ir efektīvas, tomēr nelielais mtDNS haplogrupu rezultātu skaits var tikt saistīts ar zemu senās DN…
