We present new measurements of the UV spectral slope $\beta$ for galaxies at $z=6-9$ in Frontier Fields cluster MACSJ0416.1-2403 and its parallel field, to an unprecedented level low stellar mass. fit synthetic population models observed energy distribution calculate by fitting a power law best-fit spectrum. With this method, we report derivation rest-frame colours program extending out $z=9$, ...

Drosophila yakuba is widespread in Africa. Here we compare the cuticular hydrocarbon (CHC) profiles and mating behavior of mainland (Kounden, Cameroon) and island (Mayotte, Sao-Tome, Bioko) populations. The strains each had different CHC profiles: Bioko and Kounden were the most similar, while Mayotte and Sao-Tome contained significant amounts of 7-heptacosene. The CHC profile of the Sao-Tome p...

The sensory and genetic bases of incipient speciation between strains of Drosophila melanogaster from Zimbabwe and those from elsewhere are unknown. We studied mating behaviour between eight strains - six from Zimbabwe, together with two cosmopolitan strains. The Zimbabwe strains showed significant sexual isolation when paired with cosmopolitan males, due to Zimbabwe females discriminating agai...
