Exposure to Bacillus thuringiensis (Bt) selects for beneficial interactions between the target insect pest (Helicoverpa armigera) and its symbiotic densovirus that enhances its performance on Bt-crops under field conditions.
The structural and pharmacological difference of the invertebrate counterpart of β-adrenergic receptor confers selective toxicity of an insecticide on honeybees and their devastating parasite Varroa mites.

Experiments show that pathogens spread more easily among relatives causing increased mortality, but such costs are cancelled out by the benefits of living with kin when pathogens are rare.

Worms' attraction to pheromones turns into repulsion when a food patch is depleted, helping them avoid already exploited territories and search for new food sources.

Seasonal selection is a general feature of Drosophila melanogaster genetic variation, occurring in North American and European populations and affecting large proportions of the genome.

The genetic and behavioral diversity of the zebra finch, both in the wild and in captivity, make it well-suited for neuroethological studies of vocal learning, culture, and social bonding.
Environmental gradients can modify a fundamental relationship between host community structure and disease, with implications for predicting disease risk in a changing world.
Measurements of specialized metabolites across a population of 800 natural Arabidopsis thaliana accessions revealed different pressures and evolutionary processes that shaped their variation and distribution across Europe.
