Host outnumbered: microbiomes and a fungal parasite interact to shape host genotype-dependent survival

Amruta Rajarajan, Manon Coone, Justyna Wolinska…·Ellen Decaestecker

The paper tests how microbiome composition affects host survival in Daphnia magna infected with a fungal parasite, finding genotype- and life-stage-dependent effects.

Warming increases richness and shapes assemblages of eukaryotic parasitic plankton

Amruta Rajarajan, Sławek Cerbin, Kingsly Chuo Beng…·Justyna Wolinska

This study shows that warming increases eukaryotic parasite richness and alters their assemblages in freshwater lakes, with stronger host-parasite richness correlations in heated lakes.

Daphnia-associated bacterial communities correlate with diet quantity, environmental conditions and epidemic size across natural outbreaks

Amruta Rajarajan, Justyna Wolinska, Jean‐Claude Walser…·Piet Spaak

The paper examines how Daphnia microbiomes vary with diet, environmental conditions, and parasite outbreaks across 13 years of field data.
