Can seminal fluid proteins be honest signals of sperm availability?

The paper models how seminal fluid peptides synchronize sperm and egg release in Drosophila, showing SP exhaustion as a key signal and limiting sexual conflict over remating behavior.

A selective bottleneck during host entry drives the evolution of new legume symbionts

This study shows that a selective bottleneck during host entry drives the evolution of legume symbionts by prioritizing competitiveness over within-host proliferation.

A within-host infection model to explore tolerance andresistance

The paper develops a theoretical model to explore how resistance and tolerance affect infection outcomes, validated using Drosophila and Providencia rettgeri, showing PLUD reflects the interplay of these factors.

Step-specific adaptation and trade-off over the course of an infection by GASP-mutation small colony variants

This study shows that GASP mutations in Xenorhabdus nematophila lead to step-specific adaptations during infection, with trade-offs between early and late infection fitness.

Estimation of the propensity for sexual selection in a cyclical parthenogen

The paper examines sexual selection in Daphnia magna by observing mating behavior and genetic markers, finding evidence of assortative mating and sperm competition.

A high-throughput technique to quantify pathogens’ virulence on the insect model Galleria mellonella

The paper develops a high-throughput method to quantify bacterial virulence using Galleria mellonella by combining spectrophotometry with a statistical approach.
