The coincidental virulence evolution hypothesis suggests that outside-host selection, such as predation, parasitism and
resource competition can indirectly affect the virulence of environmentally-growing bacterial pathogens. While there are
some examples of coincidental environmental selection for virulence, it is also possible that the resource acquisition and
enemy defence is selecting against it. To test these ideas we conducted an evolutionary experiment by exposing the
opportunistic pathogen bacterium Serratia marcescens to the particle-feeding ciliate Tetrahymena thermophila, the surfacefeeding
amoeba Acanthamoeba castellanii, and the lytic bacteriophage Semad11, in all possible combinations in a simulated
pond water environment. After 8 weeks the virulence of the 384 evolved clones were quantified with fruit fly Drosophila
melanogaster oral infection model, and several other life-history traits were measured. We found that in comparison to
ancestor bacteria, evolutionary treatments reduced the virulence in most of the treatments, but this reduction was not
clearly related to any changes in other life-history traits. This suggests that virulence traits do not evolve in close relation
with these life-history traits, or that different traits might link to virulence in different selective environments, for example
via resource allocation trade-offs.

Glyphosate-based herbicide use affects individual microbial taxa in strawberry endosphere but not the microbial community composition
Mathew, Suni Anie; Fuchs, Benjamin; Nissinen, Riitta; Helander, Marjo; Puigbò, Pere; Saikkonen, Kari; Muola, Anne (Oxford University Press (OUP), 2023)Aims In a field study, the effects of treatments of glyphosate-based herbicides (GBHs) in soil, alone and in combination with phosphate fertilizer, were examined on the performance and endophytic microbiota of garden ... -
Strong Regionality and Dominance of Anaerobic Bacterial Taxa Characterize Diazotrophic Bacterial Communities of the Arcto-Alpine Plant Species Oxyria digyna and Saxifraga oppositifolia
Gopala Krishnan, Manoj Kumar; van Elsas, Jan Dirk; Nissinen, Riitta (Frontiers Research Foundation, 2017)Arctic and alpine biomes are most often strongly nitrogen-limited, and hence biological nitrogen fixation is a strong driver of these ecosystems. Both biomes are characterized by low temperatures and short growing seasons, ... -

Endosphere microbial community assemblage of an inland sand dune colonizing plant
Poosakkannu, Anbu (University of Jyväskylä, 2016)Plant-associated microbes could play a role in plant colonization of sand dune ecosystems, but microbes associated with plants colonizing those ecosystems in the arctic are poorly known. I characterized Deschampsia ... -
Year-round activity of microbial communities in cold-climate peatlands treating mining-affected waters
Kujala, Katharina; Postila, Heini; Heiderscheidt, Elisangela; Maljanen, Marja; Tiirola, Marja (Elsevier, 2024)Pristine peatlands are typically low in nitrogen, sulfur and metal compounds. Thus, input of high concentrations of those compounds as a result of anthropogenic activity pose a huge challenge to peatland ecosystems. At a ...
