Landscape structure drives eco-evolution in host-parasite systems.

J. N. Deshpande, V. Dakos, O. Kaltz, E. A. Fronhofer

The paper develops an eco-evolutionary model of host-parasite dynamics on spatial networks, showing virulence is unimodal with dispersal and kin selection drives virulence evolution.

Predicting evolution in experimental range expansions of an aquatic model system

G. Zilio, S. Krenek, C. Gougat-Barbera, E. A. Fronhofer, O. Kaltz

The paper predicts range expansion dynamics in Paramecium caudatum using experimental evolution and mathematical modeling, finding that short-term evolution is driven by dispersal and growth selection, with long-term emergence of a dispersal syndrome.

Genetic diversity and connectivity of the Ostreid herpesvirus 1 populations in France: a first attempt to phylogeographic inference for a marine mollusc disease

J. Delmotte, C. Pelletier, B. Morga, R. Galinier, B. Petton, J.-B. Lamy, O. Kaltz, J.-C. Avarre, M. Jacquot, C. Montagnani, J.-M. Escoubas

The paper uses phylodynamic approaches to analyze genetic diversity and connectivity of OsHV-1 populations in French oyster-farming areas, revealing Marennes-Oleron Bay as the main source of diversity.

Parasitism and host dispersal plasticity in an aquatic model system

G. Zilio, L. S. Noergaard, G. Petrucci, N. Zeballos, C. Gougat-Barbera, E. A. Fronhofer, O. Kaltz

This study investigates dispersal plasticity in Paramecium caudatum in response to parasitism by Holospora undulata, finding strain-specific effects on dispersal and swimming speed.

Host-parasite dynamics set the ecological theatre for the evolution of state- and context-dependent dispersal in hosts

J. N. Deshpande, O. Kaltz, E. A. Fronhofer

This study shows that host dispersal evolves to be state- and context-dependent in host-parasite metapopulations, with dispersal bias driven by kin selection and influenced by parasite prevalence and host density.

Travelling with a parasite: the evolution of resistance and dispersal syndrome during experimental range expansion

G. Zilio, L. S. Noergaard, C. Gougat-Barbera, M. D. Hall, E. A. Fronhofer, O. Kaltz

This study examines how parasite presence during experimental range expansions affects host dispersal syndromes and resistance evolution in Paramecium caudatum.

When enemies do not become friends: Experimental evolution of heat-stress adaptation in a vertically transmitted parasite

E. Dusi, S. Krenek, T. Petzoldt, O. Kaltz, T. Berendonk

This study shows vertically transmitted parasites can evolve heat stress adaptations that harm hosts without improving their survival.

Phage steering of antibiotic-resistance evolution in the bacterial pathogen Pseudomonas aeruginosa

J. Gurney, L. Pradier, J. S. Griffin, C. Gougat-Barbera, B. K. Chan, P. E. Turner, O. Kaltz, M. E. Hochberg

This study shows that phage OMKO1 can reduce antibiotic resistance in Pseudomonas aeruginosa both in vitro and in vivo, by selecting for antibiotic sensitivity and phage resistance.
