Introduction
Currently rat parasites in Helsinki Urban Rat Project and on pathogens and microbiota in Swiss ticks with Barbara Tschirren. I did my PhD on the intestinal parasites of mouse lemurs: field work in Madagascar, laboratory work with 18S and 454 sequencing and statistics&bioinformatics. I also did a small side project on interactions between parasites and gut microbiota. I'm also interested in didactics of biology - understanding of genetics and using mobile gaming for biology teaching.

Article
While it is known that intestinal parasite communities vary in their composition over time, there is a lack of studies addressing how variation in component communities (between-hosts) manifests in infracommunities (within-host) during the host lifespan. In this study, we investigate the changes in the intestinal parasite infracommunities in wild-l...

1. Detecting interaction between species is notoriously difficult, and disentangling species associations in host-related gut communities is especially challenging. Nevertheless, due to contemporary methods, including metabarcoding and 16S sequencing, collecting observational data on community composition has become easier and much more common. 2....

Ecological factors, host characteristics and/or interactions among microbes may all shape the occurrence of microbes and the structure of microbial communities within organisms. In the past, disentangling these factors and determining their relative importance in shaping within-host microbiota communities has been hampered by analytical limitations...

Environmental conditions change rapidly along elevational gradients and have been found to affect community composition in macroscopic taxa, with lower diversity typically observed at higher elevations. In contrast, microbial community responses to elevation are still poorly understood. Specifically, the effects of elevation on vector-associated mi...

Lyme disease is a tick-borne disease caused by bacteria of the genus Borrelia. The disease can initially manifest as an erythema migrans rash and, if able to evade the host immune defenses, can progress into a secondary stage chronic disease with debilitating physical or neurological manifestations1,2. The host factors that modulate susceptibility...

Sex/gender is an interesting phenomenon in biological and social sciences. It is characterised by constant redefinitions and conflicts as knowledge increases and social norms change. To understand the change in sex/gender representations in biology education, we analysed Finnish secondary school human biology textbooks from the 1990s until the most...

Background Investigations of evolution knowledge and acceptance and their relation are central to evolution education research. Ambiguous results in this field of study demonstrate a variety of measuring issues, for instance differently theorized constructs, or a lack of standardized methods, especially for cross-country comparisons. In particular,...

The most common method for rodent control worldwide is the use of anticoagulant rodenticides (ARs), which block the vitamin K cycle and thus cause death by haemorrhage. First-generation anticoagulant rodenticides (FGARs) were introduced into the pest control already in the 1940s and some of them are still in use. Second-generation anticoagulant rod...

The lack of standardised assessment of evolutionary knowledge and acceptance of evolution across Europe makes comparisons between studies difficult. The Evolution Education Questionnaire on Acceptance and Knowledge (EEQ) was constructed to measure attitudes and understanding across Europe and beyond. We aimed to compile a brief instrument to allow...

Article
Experimental field studies have demonstrated negative fitness consequences of Hen Flea Ceratophyllus gallinae infestations for bird hosts, yet it is currently unclear if these negative effects are a direct consequence of flea‐induced blood loss or a result of flea‐borne pathogen transmission. Here we used a 16S rRNA sequencing approach to character...

Science education strives to increase interest in science and facilitate active citizenship. Thus, the aspects of personal and societal relevance are increasingly emphasised in science curricula. Still, little is known about how teachers choose content for their teaching, although their choices translate curricula to teaching practice. We explored...

The factors shaping microbial communities within organisms are still poorly understood. Besides ecological factors and host characteristics, direct interactions among microbes may shape the occurrence of microbes and the structure of communities. In the past it has been difficult to disentangle if patterns of microbial co-occurrence are due to faci...

Anuran parasites are poorly surveyed, despite arguably being one of the most important threats to Anuran populations worldwide. Additionally, parasites also interact with a number of other stressors, such as invasive species, pollution, sedimentation and changing light conditions, caused by anthropogenic disturbance in natural habitats. We aimed to...

Sympatric species are known to host the same parasites species. Nevertheless, surveys examining parasite assemblages in sympatric species are rare. To understand how parasite assemblages in sympatric host species differ in a given locality, we used a noninvasive identification method based on high-throughput sequencing. We collected fecal samples f...

Importance: While microbiome research has blossomed in recent years, there is a lack of longitudinal studies on microbiome dynamics on free-ranging hosts. To fill this gap, we have followed mouse lemurs, small heterothermic primates, for two years. Most studied animals have shown stable microbiota over the lifespan of host individuals, but some pr...

Parasite community dynamics is one of the central themes in contemporary parasitology. While between-host dynamics has been studied for a long time, within-host dynamics is less well studied. My aim was to identify which factors affect the parasite community during the lifetime of individual hosts by following longitudinally several individuals fro...

Body condition may be an important indicator for many infectious diseases and parasites, and may ultimately affect an individual's fitness. Although some research has correlated body condition and parasite loads in other nonhuman primates, little information has been investigated in prosimian primates. In this study we compare parasitic infections...

Genetics is a fast-developing field and it has been argued that genetics education is lagging behind. Genetics education has for example been suspected of indoctrinating strong genetic determinism. As the updating of the national upper secondary school curricula is about to start, we decided to study how the current curriculum manifests in Finnish...

Genetics education is under wide pressure for a change as the genetics is a fast-advancing field of science and the societal and cultural reprecussions of genetics are constantly increasing. The traditional teaching based on the Mendel’s pea experiments is widely acknowledged as a poor starting point for understanding genetics, though it’s globally...

Patogeenit ja loiset ovat merkittävä evolutiivinen tekijä, koska ne ovat yleisiä. Näiltä suojautuminen on evolutiivisesti merkittävä tekijä ja tärkeä trade-off: Immuunipuolustuksen ylläpito on kallista, mutta toisaalta edistää selviytyvyyttä. Selkärangattomilla ei ole yhtä hienostunutta immuunipuolustusta kuin selkärankaisilla, mutta on esitetty ar...

Project
This project explores the historical context of bird feeding and rat conflicts, in order to understand why people want to feed certain urban animals while others are unwanted neighbors. This study is funded by HELSUS – Helsinki Institute of Sustainability and HiLIFE – Helsinki Institute of Life Sciences. It is conducted at the University of Helsinki and linked to the Helsinki Urban Rat Project.
Project
The project aims to assess spatiotemporal dynamics and genetic structure of rat population in the city of Helsinki and how this affects viral, bacterial and parasite communities within rats. Additionally, we will explore zoonotic potential of rats, perceptions of citizens towards rats and damage done by rats living in buildings.
Project
My MSc project in educational sciences started out by doing a upper secondary school textbook analysis on gene models. The project has later on expanded to interviews of teachers and questionnaires on their students on their understanding of the structure and function of genes and how they see genes affecting the phenotype.
