Our study is among few studies showing the implications of multiple species interactions on an evolving host-parasite system, and it suggests a previously unreported overlap of bacterial defence against predation and parasitism in microbial consumer-resource communities.
In this host-parasite system the most common egg colours were white and blue, with no significant difference in parasitism rates between hosts laying eggs of either colour.
Because this is a host-parasite system it might be expected that immune-related gene expression in the host is altered because of parasitism.
Additionally, it might be interesting to explore the implications of linkage for parasitism of the system by non-functional RNAs.
Apart from studies in Lake Malawi [ 21, 33] and Lake Victoria [ 25, 26], and despite recent renewed interest in cichlid parasites [ 34- 37], the influence of parasitism and the immune system on cichlid speciation has hardly been considered.
Choosing other species that account for larger parasitism rates in agricultural systems will improve our understanding of how Bt crops affect parasitoids and whether any effects are due to the direct effect of Bt toxin or to prey in poor condition from feeding on Bt toxin.
But the beauties of this system — call it parasitism — is that it is very rare to encounter a challenger who cannot be co-opted.
Besides their role in nutrition, these are thought to play an important role in manipulating the host reproductive system through reproductive parasitism, i.e., feminization of genetic males, parthenogenesis and cytoplasmic incompatibilities, thereby increasing the frequency of infected females in the host population [77] [82].
Here, we test this hypothesis by conducting comparative analyses of mammalian sleep, immune system parameters, and parasitism.
In addition, a complex suite of factors involving temperature may affect patterns of parasitism and resistance in this system.
