Testate amoebae community analysis as a tool to assess biological impacts of peatland use
2018
As most ecosystems, peatlands have been heavily exploited for different human purposes. For example, in Finland the majority is under forestry, agriculture or peat mining use. Peatlands play an important role in carbon storage, water cycle, and are a unique habitat for rare organisms. Such properties highlight their environmental importance and the need for their restoration. To monitor the success of peatland restoration sensitive indicators are needed. Here we test whether testate amoebae can be used as a reliable bioindicator for assessing peatland condition. To qualify as reliable indicators, responses in testate amoebae community structure to ecological changes must be stronger than ra…

Tērvetes reģiona kultūrainavas attīstība dzelzs laikmetā un viduslaikos
2022
Darba aktualitāte izriet no tā, ka detalizēti vēsturisko novadu kultūras ainavas pētījumi Latvijā veikti ļoti reti, un arī par Tērveti nav pieejams neviens padziļināts darbs par dzels laikmetu un viduslaiku ainavu, kad veidojās nozīmīgi cilvēku darbības rezultātā atstāti uzslāņojumi. Darba mērķis ir, balstoties uz dzelzs laikmeta un viduslaiku apdzīvotības liecībām, rekonstruēt Tērvetes reģiona apdzīvotību un salīdzināt tās raksturu dažādos vēstures periodos. Darbā veikta Tērvetes reģionā esošo kultūrainavas vietu (dzīvesvietas, kapulauki, svētvietas u. c.) identificēšana un lokalizēšana, balstoties uz lietiskajiem un rakstītajiem avotiem. Šī informācija interpretēta, izmantojot ainavu arhe…
Cesijas priekšmets
2018
Cesijas rezultātā notiek saistību tiesību pāreja no vienas personas otrai, tomēr ne visas saistības var cedēt, sakarā ar to, ka likumā skaidri nav noteikts kādas saistības var un kādas nevar būt par cesijas priekšmetu arī praksē nav viennozīmīgas skaidrības par cesijas priekšmetu. Bakalaura darbā ir pētīts cesijas priekšmeta jēdziens, veidi un ierobežojumi, kā arī šādu darījumu sekas. Pētījuma mērķis ir noskaidrot iespējamos cesijas priekšmetus, pētījums ir vērsts uz pašreizējā normatīvo aktu regulējuma izpētīšanu nevis tiesisko uzlabojumu ieteikumiem. Darba rezultātā autors nonāca pie dažādām atziņām par to, kādus prasījumus var cedēt un kādi ierobežojumi pastāv cesijai.
Changing forest stakeholders’ perception of ecosystem services with linguistic nudging
2019
This paper explores whether the perceptions of forest owners and professionals could be nudged towards more sustainable management practices by adjusting a policy text's metaphorical content. Recent research has demonstrated a link between information interventions and preference change, but there is a need to further explore individuals' reactions to information on forest-based ecosystem services and to link these to the design of policy instruments. We contribute to narrowing this gap by nudging the content of a policy text comparing rotation forest management (RFM) and continuous cover forestry (CCF), and exposing it to forest stakeholders. The research is carried out in Finland, the so-…
Managing a boreal forest landscape for providing timber, storing and sequestering carbon
2015
Human well-being highly depends on ecosystem services and this dependence is expected to increase in the future with increasing population and economic growth. Studies that investigate trade-offs between ecosystem services are urgently needed for informing policy-makers. We examine the trade-offs between a provisioning (revenues from timber selling) and regulating (carbon storage and sequestration) ecosystem services among seven alternative forest management regimes in a large boreal forest production landscape. First, we estimate the potential of the landscape to produce harvest revenues and store/sequester carbon across a 50-year time period. Then, we identify conflicts between harvest re…

Data-Driven Interactive Multiobjective Optimization Using a Cluster-Based Surrogate in a Discrete Decision Space
2019
In this paper, a clustering based surrogate is proposed to be used in offline data-driven multiobjective optimization to reduce the size of the optimization problem in the decision space. The surrogate is combined with an interactive multiobjective optimization approach and it is applied to forest management planning with promising results. peerReviewed
The conservation potential of brook-side key habitats in managed boreal forests
2011
Today, maintaining biodiversity is included in the targets of boreal forest management. A widespread approach in northern Europe is to identify and preserve woodland key habitats within managed forests. Woodland key habitats are expected to be patches that host populations of threatened and declining species, and the preservation of these patches is assumed to enable the persistence of the focal species in the landscape. In Finland, the criteria for selecting woodland key habitats are defined in the Finnish Forest Act, and the selection has been done by forest practitioners. Our objective was to determine whether the surroundings of boreal brooks and rivulets qualified as key habitats are t…
