Predictable and divergent change in the multivariate P-matrix during parallel adaptation

The paper examines how phenotypic covariance evolves during adaptation in stickleback populations, finding divergent P-matrix changes in freshwater environments.

Locomotor effects of a fibrosis-based immune response in stickleback fish

This study shows that fibrosis immune response in stickleback fish improves locomotor performance despite increased body stiffness, revealing unexpected fitness consequences of immune responses.

Opening a can of worms: a test of the coinfection facilitation hypothesis

The study tests if S. solidus infection facilitates other parasite infections in stickleback, finding higher parasite richness in infected individuals.

The dominance of coinfecting parasites' indirect effects on host traits

This paper investigates how indirect genetic effects (IGEs) from coinfecting parasites influence host traits and shows that dominance of these effects can alter parasite evolution.

Local adaptation and host specificity to copepod intermediate hosts by the Schistocephalus solidus tapeworm

The paper tests if the tapeworm Schistocephalus solidus is locally adapted and host specific to copepod intermediate hosts, finding no local adaptation but host specificity between copepod genera.

Population genomics of a threespine stickleback tapeworm in Vancouver Island

The paper examines genetic structuring in tapeworm populations and their fish hosts using ddRAD sequencing, finding greater genetic differentiation in fish than in tapeworms.

Evidence of divergent selection in a parasite due to its host immunological respond

The paper examines if fibrosis in threespine stickleback fish leads to divergent selection in its tapeworm Schistocephalus solidus by analyzing whole-genome sequences.

Elemental content of a host-parasite relationship in the threespine stickleback

The paper measures elemental content and ratios in host and parasite pairs to assess stoichiometric relationships in a host-parasite system.

Single-cell RNA sequencing reveals micro-evolution of the stickleback immune system

This study uses single-cell RNA sequencing to show microevolution of immune cell structure in sticklebacks, linking cell type variation to parasite resistance differences.

Complex community-wide consequences of consumer sexual dimorphism

The paper shows that consumer sexual dimorphism can significantly affect resource coexistence, abundance, and dynamics in a two-resource, one-consumer model.

Sick of Eating: eco-evo-immuno dynamics of predators and their trophically acquired parasites

The paper examines eco-evo-immuno dynamics in predators consuming prey with different parasites, finding a potential negative correlation between parasite intake and infection when evolutionary tradeoffs are weak.

Evolution of a costly immunity to cestode parasites is a pyrrhic victory

The paper shows that freshwater stickleback populations evolved resistance to tapeworms through fibrosis, but this resistance reduced fecundity, leading to selection for a tolerant strategy with fibrosis suppression.

Interacting phenotypes and the coevolutionary process: Interspecific indirect genetic effects alter coevolutionary dynamics

This study adapts social evolution theory to interspecific interactions, showing that indirect genetic effects can drive coevolution even without direct selection or genetic variance in one species.

What evolutionary processes maintain MHCIIβ diversity within and among populations of stickleback?

The paper tests hypotheses for maintaining MHCIIβ diversity in stickleback populations using parasite data and finds neutral processes better explain diversity than selection models.

Immune gene expression covaries with gut microbiome composition in stickleback

The paper examines correlations between immune gene expression and gut microbiome composition in stickleback fish, identifying microbial families linked to immune processes.

A test of the Baldwin Effect: Differences in both constitutive expression and inducible responses to parasites underlie variation in host response to a parasite

This study tests the Baldwin Effect in stickleback fish resistance to a parasite, finding no support for the effect but highlighting the role of constitutive and inducible gene expression variation in host-parasite interactions.

Phylogenetically conserved peritoneal fibrosis response to an immunologic adjuvant in ray-finned fishes

The paper investigates whether peritoneal fibrosis in sticklebacks is a conserved immune response or a derived trait, finding it is a common, deeply conserved fish response co-opted by sticklebacks against a parasite.

Rapid Evolution of Parasite Resistance via Improved Recognition and Accelerated Immune Activation and Deactivation

This study investigates how three threespine stickleback populations differ in their immune response to a tapeworm, finding that resistant populations recognize the parasite, activate fibrosis faster, and attenuate it more effectively than susceptible populations.

Immune-challenged vampire bats produce fewer contact calls

This study shows that immune-challenged vampire bats produce fewer contact calls when isolated, potentially reducing social interactions.

A Multivariate View of Parallel Evolution

The paper introduces multivariate methods to assess parallel evolution by analyzing covariance matrices, revealing greater parallelism in stickleback evolution than previously detected.

Repeatability of adaptive radiation depends on spatial scale: regional versus global replicates of stickleback in lake versus stream habitats

This study examines how the repeatability of adaptive radiation in stickleback fish varies with spatial scale, finding greater parallel evolution at regional than global scales.

Scale-dependent effects of geography, host ecology, and host genetics, on species composition and co-occurrence in a stickleback parasite metacommunity

The paper examines how geography, host ecology, and genetics influence parasite species composition and co-occurrence across different spatial scales in a stickleback fish metacommunity.

Recent evolution of cestode growth suppression by threespine stickleback

This study shows threespine stickleback evolved heritable differences in suppressing cestode growth, with low-infection populations dramatically reducing parasite size compared to high-infection populations.
