Local adaptation of a fungal pathogen to temperature along a latitudinal gradient

The paper examines how a fungal pathogen adapts to temperature along a latitudinal gradient and finds local thermal adaptation but not host adaptation.

Phenology of plant reproduction, foliar infection, and herbivory change along an urbanization gradient

This study examines how urbanization affects plant reproduction, foliar infection, and herbivory in two weed species across an urbanization gradient.

Virulent disease epidemics can increase host density by depressing foraging of hosts

The paper shows that virulent parasites can increase host density by reducing infected hosts' foraging rates, leading to a hydra effect in ecosystems.

Facilitative priority effects drive parasite assembly under coinfection

The paper shows that early parasite infections can increase susceptibility to later infections, altering parasite assembly in hosts, with effects dependent on host and parasite genotypes.
