Social hosts evade predation but have deadlier parasites

The paper shows that predator-induced host social grouping increases parasite transmission, favoring more virulent parasites, and finds that high predation guppy populations have more virulent Gyrodactyus spp. parasites.

Metamorphosis imposes variable constraints on genome expansion

The paper investigates how metamorphosis constrains genome expansion in salamanders, finding that more extensive and synchronous remodeling imposes stricter limits on genome size.

Multiple generations of antibiotic exposure and isolation influence host fitness and the microbiome in a model zooplankton species

This study examines how multiple generations of antibiotic exposure and isolation affect host fitness and microbiome composition in Daphnia magna, finding rapid microbiome recovery but diversity loss due to isolation.

Targeted manipulation of abundant and rare taxa in the Daphnia magna microbiota with antibiotics impacts host fitness differentially

This study manipulates abundant and rare taxa in Daphnia magna microbiota with antibiotics and finds that removing abundant taxa has greater impacts on host fitness than rare taxa, with temperature affecting microbial responses.

Establishing the phenotypic basis of adherent-invasive Escherichia coli (AIEC) pathogenicity in intestinal inflammation

This study investigates AIEC pathogenicity in intestinal inflammation by linking in vitro phenotypes to in vivo disease severity in a murine model.
