Individual level microbial communities in the digestive system of the freshwater isopod Asellus aquaticus: Complex, robust and prospective (2023)
Journal Article
Liao, A., Hartikainen, H., & Buser, C. C. (2023). Individual level microbial communities in the digestive system of the freshwater isopod Asellus aquaticus: Complex, robust and prospective. Environmental Microbiology Reports, 15(3), 188-196. https://doi.org/10.1111/1758-2229.13142

The freshwater isopod Asellus aquaticus is an important decomposer of leaf detritus, and its diverse gut microbiome has been depicted as key contributors in lignocellulose degradation as of terrestrial isopods. However, it is not clear whether the in... Read More about Individual level microbial communities in the digestive system of the freshwater isopod Asellus aquaticus: Complex, robust and prospective.

Parasite DNA detection in water samples enhances crayfish plague monitoring in asymptomatic invasive populations (2021)
Journal Article
Sieber, N., Hartikainen, H., Krieg, R., Zenker, A., & Vorburger, C. (2022). Parasite DNA detection in water samples enhances crayfish plague monitoring in asymptomatic invasive populations. Biological Invasions, 24(1), 281-297. https://doi.org/10.1007/s10530-021-02644-y

Invasive species can facilitate the spread of pathogens by first providing asymptomatic host reservoirs, and then driving disease outbreaks in native populations through pathogen spillover. An example of this are invasive crayfish species in Europe (... Read More about Parasite DNA detection in water samples enhances crayfish plague monitoring in asymptomatic invasive populations.

Exploration of the 2016 Yellowstone River fish kill and proliferative kidney disease in wild fish populations (2021)
Journal Article
Hutchins, P. R., Sepulveda, A. J., Hartikainen, H., Staigmiller, K. D., Opitz, S. T., Yamamoto, R. M., …Okamura, B. (2021). Exploration of the 2016 Yellowstone River fish kill and proliferative kidney disease in wild fish populations. Ecosphere, 12(3), Article e03436. https://doi.org/10.1002/ecs2.3436

Proliferative kidney disease (PKD) is an emerging disease that recently resulted in a large mortality event of salmonids in the Yellowstone River (Montana, USA). Total PKD fish mortalities in the Yellowstone River were estimated in the tens of thousa...

Estimating species distribution and abundance in river networks using environmental DNA (2018)
Journal Article
Rinaldo, A., Carraro, L., Bertuzzo, E., Hartikainen, H., & Jokela, J. (2018). Estimating species distribution and abundance in river networks using environmental DNA. Proceedings of the National Academy of Sciences, 115(46), 11724-11729. https://doi.org/10.1073/pnas.1813843115

All organisms leave traces of DNA in their environment. This environmental DNA (eDNA) is often used to track occurrence patterns of target species. Applications are especially promising in rivers, where eDNA can integrate information about population...

Assessing myxozoan presence and diversity using environmental DNA (2016)
Journal Article
Okamura, B., Hartikainen, H., Green, A. J., Bass, D., Knipe, H., & Briscoe, A. G. (2016). Assessing myxozoan presence and diversity using environmental DNA. International Journal for Parasitology, 46(12), 781-792. https://doi.org/10.1016/j.ijpara.2016.07.006

Amplicon sequencing on a High Throughput Sequencing platform (custom barcoding) was used to detect and characterise myxosporean communities in environmental DNA samples from marine and freshwater environments and in faeces of animals that may serve a...

Diversification and repeated morphological transitions in endoparasitic cnidarians (Myxozoa: Malacosporea) (2014)
Journal Article
Hartikainen, H., Gruhl, A., & Okamura, B. (2014). Diversification and repeated morphological transitions in endoparasitic cnidarians (Myxozoa: Malacosporea). Molecular Phylogenetics and Evolution, 76(1), 261-269. https://doi.org/10.1016/j.ympev.2014.03.010

Malacosporeans are a poorly known myxozoan clade that uniquely demonstrates a tissue level of organisation. Thus, when exploiting their invertebrate hosts (freshwater bryozoans) they occur as non-motile sacs or vermiform stages capable of active swim...

Mikrocytids Are a Broadly Distributed and Divergent Radiation of Parasites in Aquatic Invertebrates (2014)
Journal Article
Hartikainen, H., Stentiford, G., Bateman, K., Berney, C., Feist, S., Longshaw, M., …Bass, D. (2014). Mikrocytids Are a Broadly Distributed and Divergent Radiation of Parasites in Aquatic Invertebrates. Current Biology, 24(7), 807-812. https://doi.org/10.1016/j.cub.2014.02.033

Microcell parasites have independently evolved in several eukaryotic lineages and are increasingly recognized as important and emerging pathogens of diverse hosts, including species of economic importance subject to international legislation concerni...

Form and metabolic scaling in colonial animals (2014)
Journal Article
Hartikainen, H., Humphries, S., & Okamura, B. (2014). Form and metabolic scaling in colonial animals. Journal of Experimental Biology, 217(5), 779-786. https://doi.org/10.1242/jeb.093484

Benthic colonial organisms exhibit a wide variation in size and shape and provide excellent model systems for testing the predictions of models that describe the scaling of metabolic rate with organism size. We tested the hypothesis that colony form... Read More about Form and metabolic scaling in colonial animals.
