Complex plant quality—microbiota–population interactions modulate the response of a specialist herbivore to the defence of its host plant
2022
Many specialist herbivores have evolved strategies to cope with plant defences, with gut microbiota potentially participating to such adaptations. In this study, we assessed whether the history of plant use (population origin) and microbiota may interact with plant defence adaptation. We tested whether microbiota enhance the performance of Melitaea cinxia larvae on their host plant, Plantago lanceolata and increase their ability to cope the defensive compounds, iridoid glycosides (IGs). The gut microbiota were significantly affected by both larval population origin and host plant IG level. Contrary to our prediction, impoverishing the microbiota with antibiotic treatment did not reduce larv…

Sysmä Community Currency: An Analysis of its Success from the Perspectives of Purposes, Stakeholders and Promotion
2019
Artikkeli on tapaustutkimus paikallisrahajärjestelmästä, jota kokeiltiin äskettäin maalaisympäristössä Sysmän kunnassa. Paikallisraha on yksi innovaatiivisista aloitteista, joita kunta on tehnyt tällä vuosituhannella torjuakseen jo 1960-luvulta alkaen käynnissä ollutta väestökatoa. Tässä artikkelissa tutkitaan paikallisrahan käynnistysvaihetta siihen sisältyneiden ristiriitojen näkökulmasta. Artikkelissa todetaan, että järjestelmä kärsi epäselvästä tavoitteenasettelusta, ja että eri osallisilla oli tavoittesta vaihtelevia ja ristiriitaisia käsityksiä. Paikallisrahan sosiaalista hyväksyntää heikensivät päätös rajoittaa rahaa vastaanottavien yritysten joukko kunnassa kirjoilla oleviin yrityks…

H&E Multi-Laboratory Staining Variance Exploration with Machine Learning
2022
In diagnostic histopathology, hematoxylin and eosin (H&E) staining is a critical process that highlights salient histological features. Staining results vary between laboratories regardless of the histopathological task, although the method does not change. This variance can impair the accuracy of algorithms and histopathologists’ time-to-insight. Investigating this variance can help calibrate stain normalization tasks to reverse this negative potential. With machine learning, this study evaluated the staining variance between different laboratories on three tissue types. We received H&E-stained slides from 66 different laboratories. Each slide contained kidney, skin, and colon tissue sampl…

Behavioural, ecological, and evolutionary aspects of diversity in frog colour patterns
2017
The role of colours and colour patterns in behavioural ecology has been extensively studied in a variety of contexts and taxa, while almost overlooked in many others. For decades anurans have been the focus of research on acoustic signalling due to the prominence of vocalisations in their communication. Much less attention has been paid to the enormous diversity of colours, colour patterns, and other types of putative visual signals exhibited by frogs. With the exception of some anecdotal observations and studies, the link between colour patterns and the behavioural and evolutionary ecology of anurans had not been addressed until approximately two decades ago. Since then, there has been eve…
Ultraviolet cues in fruit-frugivore interactions
2002
All diurnal birds studied so far, many reptiles, amphibians, fish and some rodents are able to detect near-ultraviolet light (UV; 320-400 nm) invisible to humans. In many animals, UV cues have been found to play a role in foraging and mate choice. As many fruits reflect UV light, frugivores sensitive to UV may also use these cues in foraging. Fruit colours and their contrast with background coloration may attract frugivores. In this thesis, I studied the fruit colour preferences of both redwings (Turdus iliacus) and small rodents (house mice, Mus musculus and bank vole, Clethrionomys glareolus).
Metaforu lietojums publikācijās par Latviju 2020. gada ārzemju presē
2021
Pētījumā tiek analizēts metaforu lietojums, galveno uzmanību pievēršot to funkciju izpētei. Metaforu funkcijas ietekmē vairāki faktori, piemēram, autora nodomi un mērķauditorija, kas nozīmē, ka tās ir cieši saistītas ar diskursu un kontekstu. Tādējādi, šajā darbā tika pētīts metaforu lietojums 2020. gada ārzemju mediju publikācijās par Latvijas jaunuzņēmumu ekosistēmu, izmantojot Džonatana Čarterisa-Bleka (2004) definēto kritiskā diskursa analīzes metodi. Balstoties uz kognitīvās metaforas teorijām, tika analizētas metaforu funkcijas un to aksioloģiskās vērtības publikācijās. Pētījuma rezultāti atklāja pārliecināšanas funkcijas daudzveidību, kā arī pozitīvo vērtību pārsvaru publikācijās par…
