Digital Solutions in the Forest-Based Bioeconomy

2019

This chapter aims to illustrate the potential and significance of forest-based industry to take the lead in the sustainable development of the bio-based economy under digitalization. The digital solutions are transforming the forest-based industry by enabling the real-time end-to-end supply chain visibility, stock level optimization, demand planning, and real-time order status tracking and transparent, speedy, and hassle-free order fulfillment. In addition, increasing diversification corresponds to eco-consciousness, and shift in people’s preferences induces the transformation of forest-based bioeconomy into a digital platform industry. Further, this chapter will highlight the circular econ…

More wood but less biodiversity in forests in Finland: a historical evaluation

2022

National forest inventories (NFI) in Finland provide empirical evidence for a marked increase in tree growth, total forest area, and total timber volume over the past century. Meanwhile, the assessments of threatened forest species and habitats indicate continuous degradation of biodiversity in Finnish forests. To shed light on this seeming paradox, we summarized the temporal patterns of forest characteristics (indicators) that have major influence on biodiversity, comparing the structure of current Finnish forests with natural and historical references. Using a variety of data sources, we estimated the proportion of area of old-growth forest and of deciduous-dominated forests, the density …

A synthesis of multi-taxa management experiments to guide forest biodiversity conservation in Europe

2023

Most European forests are used for timber production. Given the limited extent of unmanaged (and especially primary) forests, it is essential to include commercial forests in the conservation of forest biodiversity. In order to develop ecologically sustainable forest management practices, it is important to understand the management impacts on forest-dwelling organisms. Experiments allow testing the effects of alternative management strategies, and monitoring of multiple taxa informs us on the response range across forest-dwelling organisms. To provide a representative picture of the currently available information, metadata on 28 multi-taxa forest management experiments were collected from…

Ancilus ezera un Litorīnas jūras krasta līnijas Ventspils lagūnas apkārtnē

2021

Secīgās Baltijas jūras attīstības stadijas ietekmējušas senās Ventspils lagūnas aptvertās teritorijas, kur konstatējami Ancilus ezera un Litorīnas jūras stadiju krasta veidojumi. Izvirzīts mērķis – detektēt un verificēt šo stadiju krasta līnijas, pielietojot automatizētu metodiku. Modelējot teritorijai atbilstošus laika periodus, iegūti 25 krasta līniju modeļi, kas apvienoti 10 krastos. Modeļi verificēti pret izveidoto reljefa modeli, kā arī attiecīgi iepriekšējo paleoģeogrāfisko un arheoloģisko pētījumu rezultātiem un šī darba laikā iegūto paraugu optiski stimulētās luminiscences datējumiem. Maģistra darbā dots precīzs skaidrojums par teritorijas attīstību akmens laikmetā, paplašinot arheo…

Exploring 2040 : Global Trends and International Policies Setting Frames for the Finnish Wood-Based Economy

2022

Global trends influence the approaches and mindset for using natural resources and technological capacities. Participatory scenario methods have proven useful in long-term foresight. However, country-level foresight studies often ignore the broader trends affecting international markets and setting frames for economic development. This study envisions which global trends could occur and how the resulting European policies might affect the Finnish forest sector’s development in 2040. We applied a Futures Wheel approach, where stakeholder groups consisting of policy-, economic- and social sustainability-, technology-, and climate sustainability -experts in the field of forestry and interlinki…

Applying the Anna Karenina principle for wild animal gut microbiota : temporal stability of the bank vole gut microbiota in a disturbed environment

2020

Gut microbiota play an important role in host health. Yet, the drivers and patterns of microbiota imbalance (dysbiosis) in wild animals remain largely unexplored. One hypothesised outcome of stress on animal microbiomes is a destabilised microbial community that is characterised by an increase in inter-individual differences compared with microbiomes of healthy animals, which are expected to be (i) temporally stable and (ii) relatively similar among individuals. This set of predictions for response of microbiomes to stressors is known as the Anna Karenina principle (AKP) for animal microbiomes. We examine the AKP in a wild mammal inhabiting disturbed environments by conducting a capture-mar…

Hakkuutähteiden korjuun ympäristövaikutukset sekä hakkuutähteiden korjuun vaikutus metsänuudistamisen kokonaiskustannuksiin

2010

Tämä opinnäytetyö käynnistettiin Vapo oy Energian tilauksesta, kun yhtiö oli aloittamassa laajamittaista hakkuutähteiden keräämistä. Opinnäytetyössä on perehdytty hakkuutähteiden keräämisen vaikutuksiin maaperässä, vesistöissä sekä muussa metsäluonnossa. Hakkuutähteiden korjuun taloudellisia vaikutuksia oli tarkoitus selvittää mahdollisimman havainnollisesti, ja muuntaa tulokset rahallisesti arvioitaviksi. Metsänuudistamisessa hakkuutähteiden keräämisellä on pääasiassa positiivisia vaikutuksia: maanmuokkaus onnistuu paremmin, istutusolosuhteet ovat helpommat ja luonnontaimien täydentävä vaikutus on suurempi kuin runsaasti hakkuutähteitä sisältävällä kohteella. Hakkuutähdekasojen alle aikais…

The impact of wildlife and environmental factors on hantavirus infection in the host and its translation into human risk

2023

Identifying factors that drive infection dynamics in reservoir host populations is essential in understanding human risk from wildlife-originated zoonoses. We studied zoonotic Puumala orthohantavirus (PUUV) in the host, the bank vole ( Myodes glareolus ), populations in relation to the host population, rodent and predator community and environment-related factors and whether these processes are translated into human infection incidence. We used 5-year rodent trapping and bank vole PUUV serology data collected from 30 sites located in 24 municipalities in Finland. We found that PUUV seroprevalence in the host was negatively associated with the abundance of red foxes, but this process did no…
