ABSTRACT The nuclear genome is essential for encoding most of the genes required for cellular processes, but its size alone can alter the characteristics of cells and organisms. Yet, genome size variation and its ecological and evolutionary impacts, particularly in microorganisms, are not well understood.

Costs of reproduction in flowering plants
Summary Costs of reproduction arise when investments into current reproduction reduce future reproductive fitness. Studies on reproductive costs use diverse approaches, including the analysis of gene expression, physiology, trade‐offs between reproduction and growth/survival, and the impact of reproductive investments on population growth.

The genetic basis of replicated bullseye pattern reduction across the Hibiscus trionum complex
Summary Colorful petal patterns fulfill important functions and constitute excellent systems to illuminate the evolutionary processes that generate morphological diversity or instead support the repetitive emergence of similar forms. Here, we combined phylogenomic approaches, genetic manipulations, molecular techniques, and bee behavioral experiments ...

Nectar metabolomes contribute to pollination syndromes
Summary ‘Pollination syndromes’, where convergent floral signals reflect selection from a functional pollinator group, are often characterized by physical features, yet floral rewards such as nectar may also reflect selection from pollinators. We asked whether nectar chemistry shows evidence of convergence across functional pollinator groups, i.e.
