Plant defense compounds play a key role in the evolution of insect–plant associations by
selecting for behavioral, morphological, and physiological insect adaptations. Sequestration …

Major evolutionary transitions can be triggered by behavioural novelty, and are often
associated with 'adaptive suites', which involve shifts in multiple co-adapted traits subject to …

Heliconius butterflies, a speciose genus of Müllerian mimics, represent a classic example of
an adaptive radiation that includes a range of derived dietary, life history, physiological and …

Sex chromosomes are evolutionarily labile in many animals and sometimes fuse with
autosomes, creating so-called neo-sex chromosomes. Fusions between sex chromosomes …

In a time with decreasing biodiversity, especially among insects, a detailed understanding
about specific resource utilization strategies is crucial. The physiological and behavioural …

Male Heliconius butterflies possess two pheromone emitting structures, wing androconia
and abdominal clasper scent glands. The composition of the clasper scent gland of males of …

Host plant specialization is a major force driving ecological niche partitioning and
diversification in insect herbivores. The cyanogenic defences of Passiflora plants keep most …

Evolutionary convergence of color pattern in mimetic species is tightly linked with the
evolution of chemical defenses. Yet, the evolutionary forces involved in natural variations of …

Covering: up to the end of 2023 Natural nitriles comprise a small set of secondary
metabolites which however show intriguing chemical and functional diversity. Various …

Abstract β-Glucosidases play an important role in the chemical defense of many insects by
hydrolyzing and thereby activating glucosylated pro-toxins that are either synthesized de …
