The influence of bacteria-dominated diets on Daphnia magna somatic growth, reproduction, and lipid composition

SJ Taipale, MT Brett, K Pulkkinen… - FEMS Microbiology …, 2012 - academic.oup.com
We explored how dietary bacteria affect the life history traits and biochemical composition of
Daphnia magna, using three bacteria taxa with very different lipid composition. Our …

Host starvation decreases parasite load and mean host size in experimental populations

K Pulkkinen, D Ebert - Ecology, 2004 - Wiley Online Library
While host stress in vertebrate populations has often been linked to outbreaks of epidemics,
which are attributed to the immuno‐compromise of the stressed hosts, no predictions have …

Environment may be the source of Flavobacterium columnare outbreaks at fish farms

HMT Kunttu, LR Sundberg, K Pulkkinen… - Environmental …, 2012 - Wiley Online Library
Flavobacterium columnare, causing columnaris disease, was isolated for the first time from
free water and biofilms in the environment outside fish farms. Fourteen isolates were found …

A three-way perspective of stoichiometric changes on host–parasite interactions

SL Aalto, E Decaestecker, K Pulkkinen - Trends in Parasitology, 2015 - cell.com
Changes in environmental nutrients play a crucial role in driving disease dynamics, but global
patterns in nutrient-driven changes in disease are difficult to predict. In this paper we use …

[HTML][HTML] Filtration of Nordic recirculating aquaculture system wastewater: Effects on microalgal growth, nutrient removal, and nutritional value

ML Calderini, Č Stevčić, S Taipale, K Pulkkinen - Algal Research, 2021 - Elsevier
Microalgal bioremediation of recirculating aquaculture system (RAS) wastewater represents
an alternative for wastewater treatment with the potential to generate valuable biomass. This …

Screening of microalgae and LED grow light spectra for effective removal of dissolved nutrients from cold-water recirculating aquaculture system (RAS) wastewater

Č Stevčić, K Pulkkinen, J Pirhonen - Algal Research, 2019 - Elsevier
Popularity of recirculating aquaculture systems (RAS) is increasing. Because of the high water
recirculation rate, dissolved nutrients originating from fish feed are concentrated enough …

Higher resource level promotes virulence in an environmentally transmitted bacterial fish pathogen

…, J Mappes, JK Valkonen, K Pulkkinen… - Evolutionary …, 2017 - Wiley Online Library
Diseases have become a primary constraint to sustainable aquaculture, but remarkably little
attention has been paid to a broad class of pathogens: the opportunists. Opportunists often …

[HTML][HTML] Lowered nutritional quality of prey decrease the growth and biomolecule content of rainbow trout fry

SJ Taipale, K Pulkkinen, O Keva, MJ Kainz… - … and Physiology Part B …, 2022 - Elsevier
Diet quality is crucial for the development of offspring. Here, we examined how the nutritional
quality of prey affects somatic growth and the lipid, carbohydrate, protein, amino acid, and …

Adaptation to a limiting element involves mitigation of multiple elemental imbalances

…, RE Sherman, C Prater, K Pulkkinen… - Journal of the …, 2023 - royalsocietypublishing.org
About 20 elements underlie biology and thus constrain biomass production. Recent systems-level
observations indicate that altered supply of one element impacts the processing of …

[HTML][HTML] Application of high resolution melting assay (HRM) to study temperature-dependent intraspecific competition in a pathogenic bacterium

R Ashrafi, M Bruneaux, LR Sundberg, K Pulkkinen… - Scientific reports, 2017 - nature.com
Studies on species’ responses to climate change have focused largely on the direct effect of
abiotic factors and in particular temperature, neglecting the effects of biotic interactions in …
