Intraspecific density changes the impact of interspecific competitors on parasite infection traits in multiple infections

D. Godinho, L. Rodrigues, S. Lefevre, S. Magalhaes, A. B. Duncan

The paper examines how intraspecific density affects the impact of interspecific competitors on parasite infection traits in multiple infections, finding independent effects on within- and between-host traits.

Rapid emergence of extensively drug-resistant Shigella sonnei in France

S. Lefevre, E. Njamkepo, S. Feldman, C. Ruckly, I. Carle, M. Lejay-Collin, L. Fabre, I. Yassine, L. Frezal, M. Pardos de la Gandara, A. Fontanet, F.-X. Weill

The paper tracks the rise of extensively drug-resistant Shigella sonnei in France, identifying genetic clusters and resistance mechanisms in isolates from 2005 to 2021.

Virulence constrains transmission even in the absence of a genetic trade-off

D. P. Godinho, L. R. Rodrigues, S. Lefevre, L. Delteil, A. F. Mira, I. R. Fragata, S. Magalhaes, A. B. Duncan

The study shows that virulence and parasite fitness have a hump-shaped relationship when transmission is not possible, but a positive correlation when transmission occurs, indicating environmental and genetic influences depending on transmission timing.

Consequences of population structure for sex allocation and sexual conflict

L. Rodrigues, M. Torralba Saez, J. Alpedrinha, S. Lefevre, M. Brengues, S. Magalhaes, A. Duncan

This study examines how dispersal type and competition scale affect sex allocation and sexual conflict in spider mites, finding that budding dispersal reduces female-biased offspring ratios and male harm.

Transgenerational cues about local mate competition affect offspring sex ratios in the spider mite Tetranychus urticae

A. Duncan, C. Marinosci, C. Devaux, S. Lefevre, S. Magalhaes, J. Griffin, A. Valente, O. Ronce, I. Olivieri

The paper shows that maternal environment influences offspring sex ratios in spider mites, suggesting females use this as a cue for local mate competition conditions.
