Macrolides from the scent glands of the tropical butterflies Heliconius cydno and Heliconius pachinus.
The four major components present in scent gland extracts of the male Costa Rica longwing butterflies Heliconius cydno and Heliconius pachinus were identified as 12- and 14-membered macrolides containing a C(18)-carbon skeleton. By use of micro-reactions and spectrometric examinations, structural proposals were made and subsequently proven by synthesis, using ring-closing-metathesis as the key ...
متن کاملCombined EST and proteomic analysis identifies rapidly evolving seminal fluid proteins in Heliconius butterflies.
Seminal fluid proteins (SFPs) directly influence a wide range of reproductive processes, including fertilization, sperm storage, egg production, and immune response. Like many other reproductive proteins, the molecular evolution of SFPs is generally characterized by rapid and frequently adaptive evolution. However, the evolutionary processes underlying this often-documented pattern have not yet...
متن کاملTranscriptional Profiles of Mating-Responsive Genes from Testes and Male Accessory Glands of the Mediterranean Fruit Fly, Ceratitis capitata
BACKGROUND Insect seminal fluid is a complex mixture of proteins, carbohydrates and lipids, produced in the male reproductive tract. This seminal fluid is transferred together with the spermatozoa during mating and induces post-mating changes in the female. Molecular characterization of seminal fluid proteins in the Mediterranean fruit fly, Ceratitis capitata, is limited, although studies sugge...
متن کاملEstimating the age of Heliconius butterflies from calibrated photographs
Mating behaviour and predation avoidance in Heliconius involve visual colour signals; however, there is considerable inter-individual phenotypic variation in the appearance of colours. In particular, the red pigment varies from bright crimson to faded red. It has been thought that this variation is primarily due to pigment fading with age, although this has not been explicitly tested. Previous ...
متن کاملHybrid trait speciation and Heliconius butterflies
Homoploid hybrid speciation (HHS) is the establishment of a novel species through introgressive hybridization without a change in chromosome number. We discuss different routes by which this might occur and propose a novel term, ‘hybrid trait speciation’, which combines the idea that hybridization can generate adaptive novelty with the ‘magic trait’ model of ecological speciation. Heliconius bu...
