Experimental evolution for improved post-infection survival selects for increased disease resistance in Drosophila melanogaster

This study shows that experimental evolution of Drosophila melanogaster under post-infection survival selection leads to increased disease resistance but not disease tolerance.

Parental effects of pathogenic bacterial infections in Drosophila melanogaster: trans-generational immune priming without apparent costs

This study shows that parental infection in Drosophila melanogaster improves offspring survival and disease resistance to both homologous and heterologous pathogens without measurable costs.

Nature and location of modifier alleles determine the resolution of intralocus sexual conflict

The paper investigates how modifier alleles resolve intralocus sexual conflict, finding that imperfect modifiers may not always resolve it and X chromosomes are generally more effective.

Selection for increased post-infection survival ameliorates mating induced immune suppression in Drosophila melanogaster females

This study shows that Drosophila melanogaster populations selected for increased post-infection survival show reduced mating-induced immune suppression compared to control populations.

Correlated responses to experimental evolution of increased post-infection survival in Drosophila melanogaster: Life-history trade-offs and reaction to novel stressors

This study shows that Drosophila melanogaster can rapidly evolve increased resistance to E. faecalis infection without life-history costs or abiotic stress resistance.

Pathogen dependence and inter-individual variability of post-infection reproductive fitness in Drosophila melanogaster

This study investigates how bacterial infections affect reproductive fitness in Drosophila melanogaster, finding that pathogen identity predicts population-level responses but not individual variability, and that infected females that survive show reproductive output similar to uninfected controls.

Discordant effects of resource limitation on host survival and systemic pathogen growth in Drosophila-bacteria infection models: resistance vs. tolerance

This study examines how resource limitation through starvation and sexual activity affects host survival and pathogen growth in Drosophila infected with bacterial pathogens, finding pathogen-specific outcomes.

Cold stress upregulates the expression of heat shock and Frost genes, but the evolution of cold stress resistance is apparently not mediated through either heat shock or Frost genes in the cold stress selected populations of Drosophila melanogaster

The study examines gene expression and lipid levels in cold-stressed Drosophila populations, finding upregulated heat shock and Frost genes but no significant differences between selected populations.

Effect of larval diet on adult immune function is contingent upon selection history and host sex in Drosophila melanogaster

This study shows that Drosophila melanogaster adapted to bacterial infections maintain better immune function under poor diets, with sex-dependent effects.

Increasing adult density compromises anti-bacterial defense in Drosophila melanogaster

This study shows that higher adult Drosophila melanogaster densities lead to increased post-infection mortality and starvation resistance, supporting the density-stress hypothesis.

Recurrent evolution of cross-resistance in response to selection for improved post-infection survival in Drosophila melanogaster

This study shows that selecting Drosophila melanogaster for resistance to one bacterial pathogen leads to generalized cross-resistance against other pathogens.

Investigating the interaction between inter-locus and intra-locus sexual conflict using hemiclonal analysis in Drosophila melanogaster

This study investigates how inter-locus and intra-locus sexual conflict interact in Drosophila melanogaster using hemiclonal analysis, finding a non-significant trend that stronger inter-locus conflict may reduce intra-locus conflict.

Cuticular hydrocarbon divergence in Drosophila melanogaster populations evolving under differential operational sex ratios

This study examines cuticular hydrocarbon divergence in Drosophila melanogaster populations under differential sexual conflict and finds no significant differences between high and low conflict regimes.

Evolutionary genetics of Drosophila melanogaster immunity: role of the X chromosome and sex-specific dominance

The paper investigates the role of the X chromosome in immune response evolution in Drosophila melanogaster and finds sex-specific dominance patterns in immunity-related alleles.

Evolution of reproductive traits have no apparent life-history associated cost in populations of Drosophila melanogaster selected for cold shock resistance

This study finds no life-history cost associated with evolved reproductive traits and increased egg viability in cold shock-resistant Drosophila melanogaster populations.

Evolution of cross-tolerance in Drosophila melanogaster as a result of increased resistance to cold stress

This study shows that increased cold stress resistance in Drosophila melanogaster correlates with increased heat tolerance but decreases starvation resistance.

Mating enhances immune function of Drosophila melanogaster populations against bacterial pathogens

This study finds that mating in Drosophila melanogaster enhances population survival against bacterial infections, with no sexual dimorphism in immune response.

Reproductive Isolation through Experimental Manipulation of Sexually Antagonistic Coevolution in Drosophila Melanogaster

This study shows that sexual conflict in Drosophila melanogaster leads to both premating and postmating reproductive isolation in allopatric populations.

Niche construction in evolutionary theory: the construction of an academic niche?

The paper critiques claims that niche construction is a significant evolutionary process, arguing that these claims are largely untenable and represent academic niche construction.

Rethinking inheritance, yet again: inheritomes, contextomes and dynamic phenotypes

The paper proposes a framework for an extended view of inheritance that integrates non-genetic mechanisms and discusses its implications for evolutionary dynamics and simulation studies.
