      description => protected'The role of interspecific hybridization in evolution is still being debated.
          Interspecific hybridization has been suggested to facilitate the evolution 
         of ecological novelty, and hence the invasion of new niches and adaptive rad
         iation when ecological opportunity is present beyond the parental species ni
         ches. On the other hand, hybrids between two ecologically divergent species 
         may perform less well than parental species in their respective niches becau
         se hybrids would be intermediate in performance in both niches. The evolutio
         nary consequences of hybridization may hence be context-dependent, depending
          on whether ecological opportunities, beyond those of the parental species, 
         do or do not exist. Surprisingly, these complementary predictions may never 
         have been tested in the same experiment in animals. To do so, we investigate
          if hybrids between ecologically distinct cichlid species perform less well 
         than the parental species when feeding on food either parent is adapted to, 
         and if the same hybrids perform better than their parents when feeding on fo
         od none of the species are adapted to. We generated two first-generation hyb
         rid crosses between species of African cichlids. In feeding efficiency exper
         iments we measured the performance of hybrids and parental species on food t
         ypes representing both parental species niches and additional ‘novel’ ni
         ches, not used by either of the parental species but by other species in the
          African cichlid radiations. We found that hybrids can have higher feeding e
         fficiencies on the 'novel' food types but typically have lower efficiencies 
         on parental food types when compared to parental species. This suggests that
          hybridization can generate functional variation that can be of ecological r
         elevance allowing the access to resources outside of either parental species
          niche. Hence, we provide support for the hypothesis of ecological context-d
         ependency of the evolutionary impact of interspecific hybridization.' (1968 chars)

      description => protected'The process of adaptive radiation was classically hypothesized to require i
         solation of a lineage from its source (no gene flow) and from related specie
         s (no competition). Alternatively, hybridization between species may generat
         e genetic variation that facilitates adaptive radiation. Here we study haplo
         chromine cichlid assemblages in two African Great Lakes to test these hypoth
         eses. Greater biotic isolation (fewer lineages) predicts fewer constraints b
         y competition and hence more ecological opportunity in Lake Bangweulu, where
         as opportunity for hybridization predicts increased genetic potential in Lak
         e Mweru. In Lake Bangweulu, we find no evidence for hybridization but also 
         no adaptive radiation. We show that the Bangweulu lineages also colonized La
         ke Mweru, where they hybridized with Congolese lineages and then underwent m
         ultiple adaptive radiations that are strikingly complementary in ecology an
         d morphology. Our data suggest that the presence of several related lineage
         s does not necessarily prevent adaptive radiation, although it constrains th
         e trajectories of morphological diversification. It might instead facilitate
          adaptive radiation when hybridization generates genetic variation, without 
         which radiation may start much later, progress more slowly or never occur.' (1290 chars)
