Courtship behavior in Drosophila melanogaster: towards a ‘courtship connectome’

The construction of a comprehensive structural, and importantly functional map of the network of elements and connections forming the brain represents the Holy Grail for research groups working in disparate disciplines. Although technical limitations have restricted the mapping of human and mouse 'connectomes' to the level of brain regions, a finer degree of functional resolution is attainable ...

Can Courtship be Cheatproof?

In 1983, I told Richard Manning about Gale and Shapley’s beautiful 1962 paper on matching. He asked whether in the Gale-Shapley it was in the interest of all participants to tell the truth. We rather quickly showed that in general it is not in the interest of the recipients of offers to be truthful. In fact we were able to show that no mechanism can guarantee efficient assignments and be cheatp...

Palaeontology: Scrapes of Dinosaur Courtship

Analysis of numerous trace fossils reveals 'nest scrape displays' made by dinosaurs that are analogous to those left by modern birds.

The Evolution of Duck Courtship

Multivariate analysis of Drosophila courtship.

Courtship records of 15 pairs of Drosophila melanogaster were analyzed for temporal stationarity of courtship behaviors, behavioral diversity, behavioral intercorrelations, sequential properties, and information transmission for both sexes. Durations of one male behavior, "orient-back," and two female behaviors, "preen" and "stand still," were found to change from the first to the second half o...
