Early learning and speciation : the effects of early experience on sexual and aggressive behaviour in Lake Victoria cichlid fish

We calculated additional summary variables as estimates of overall parasite infestation rate: TPL (total parasite load; the sum of all parasites infecting one fish), PS (the

Here we present experimental evi- dence for a mechanism by which sexual selection becomes divergent: in two sib- ling species from Lake Victoria, female mating preferences for red

Moreover, the hue of male red coloration (dorsal hue) was significantly different between populations: Kissenda males had higher hue values, i.e. These two measures are

omnicaeruleus males are sneakers: yellow males with mature testes were rare in our field sample (Figure 7.1) and the relationship between size and gonadal maturity stage did

Quantitative analysis of carotenoid availability and parasite infestation rates in different populations are required to investigate this hypothesis (e.g. Grether et al. Finally,

In 2003 heb ik in Leiden een congres georganiseerd voor jonge evolutio- nair biologen, over ‘Sex, Sexual Selection and Speciation’. Daarna heb ik een symposium georganiseerd
