Clear effects of population and sex but not rearing temperature on stress tolerance in a temperate butterfly

This study examines how population, sex, and rearing temperature affect stress tolerance in Glanville fritillary butterflies, finding no evidence for beneficial acclimation but highlighting population and sex interactions.

Doors and corners of variance partitioning in statistical ecology

The paper presents a Bayesian framework for variance partitioning in ecological studies, demonstrating its application through a butterfly metapopulation case study and highlighting challenges in interpreting variance components.

Thermal plasticity in protective wing pigmentation is modulated by genotype and food availability in an insect model of seasonal polyphenism.

This study examines how temperature and food availability interact to influence wing pigmentation in Bicyclus anynana butterflies, showing genotype-specific thermal plasticity and nutritional effects.

Species-associated bacterial diversity increases along a gradient of habitat degradation

The paper examines how bacterial diversity in herbivorous insects changes with habitat degradation and finds that diversity increases while community composition remains stable.

Exploring links between climatic predictability and the evolution of within- and transgenerational plasticity

The paper investigates how climatic predictability influences the evolution of within- and transgenerational plasticity in a temperate butterfly using time series and common garden experiments.

Alternative developmental and transcriptomic responses to host plant water limitation in a butterfly metapopulation

The paper examines developmental and transcriptomic responses to water-limited host plants in a butterfly metapopulation, revealing heritable variability in plasticity.

Multidimensional plasticity in the Glanville fritillary butterfly: larval performance curves are temperature, host and family specific.

The paper examines how temperature, host plant, and family variation affect larval performance traits in Glanville fritillary butterflies, finding significant intraspecific variation and host-dependent responses.

Summer drought decreases the predictability of local extinctions in a butterfly metapopulation

The paper examines how summer drought affects the predictability of local extinctions in a butterfly metapopulation, finding that drought reduces the informativeness of traditional covariates.

Narrow oviposition preference of an insect herbivore risks survival under conditions of severe drought

The study examines how drought stress affects oviposition preferences and offspring survival in Glanville fritillary butterflies, finding that preferred microhabitats may increase offspring risk under extreme drought.

Evolutionary and ecological processes influencing chemical defense variation in an aposematic and mimetic Heliconius butterfly

This study investigates intraspecific variation in cyanogenic toxicity in Heliconius erato, finding substantial variation and potential for adaptive evolution despite limited dietary influence.

Variation in Melitaea cinxia gut microbiota is phylogenetically highly structured but only mildly driven by host plant microbiota, sex or parasitism.

The study examines gut microbiota variation in Glanville fritillary caterpillars, finding high phylogenetic structure and limited influence from host plant microbiota, sex, or parasitism.

Landscape permeability and individual variation in a dispersal-linked gene jointly determine genetic structure in the Glanville fritillary butterfly

The paper shows that landscape permeability and individual dispersal variation jointly shape genetic structure in a butterfly metapopulation during expansion.

Every cloud has a silver lining: Moderate plant water stress positively impacts development, immunity, and gut microbiota of a specialist herbivore

The study shows that moderate plant water stress improves larval growth, gut microbial diversity, and immune gene expression in the Glanville fritillary butterfly.

Extensive phenotypic plasticity in a seasonal butterfly limits potential for evolutionary responses to environmental change

The paper examines phenotypic plasticity in a seasonal butterfly and finds that limited genetic variation for plasticity may restrict evolutionary responses to climate change.
