Ecosystem effects of aquatic microbial diversity
Arianna’s research clusters around three main scientific questions:
- How does intraspecific diversity structure marine phytoplankton communities and provide evidence for their future resilience to environmental change?
- Past projects that support this emphasis area: Krinos et al. 2025 Ecology Letters, laboratory experiments with combined temperature and nutrient effects on strains
- Current projects that support this emphasis area: forthcoming work to characterize coccolithophore intraspecific diversity
- How do phytoplankton compete for resources in coastal ecosystems over temporal scales, and how does this result in changes in species succession?
- Past projects that support this emphasis area: Krinos et al. 2026 submitting to Global Change Biology, Lake Mendota work
- Current projects that support this emphasis area: Collaborative work with the Brisbin lab at USF, Collaborative work at the Salton Sea in California, Collaborative work with Bridge-to-PhD fellow Emily Hu
- What is the relationship between taxonomic diversity and functional redundancy in marine microbes (or, eukaryotes)?
- Past projects that support this emphasis area: EUKulele (Krinos et al. 2021), eukrhythmic (Krinos et al. 2023), tax-aliquots/cryptic taxonomic diversity (Krinos et al. 2024)
- Current projects that support this emphasis area: using metatranscriptomic data to tune models with meaningful taxonomic subgroupings (Krinos et al. 2026 in prep), Multiscale modeling framework with C-CoMP, 2025 C-CoMP cruises data analysis
