         both the density and traits of their hosts. Such changes in ecosystems are p
         articularly likely when the host is a predator that mediates the dynamics of
          trophic cascades. Here, we experimentally tested how parasite load of a sma
         ll predatory fish, the threespine stickleback, can affect the occurrence and
          strength of trophic cascades and ecosystem functioning. In a factorial meso
         cosm experiment, we manipulated the density of stickleback (low vs. high), a
         nd the level of parasite load (natural vs. reduced). In addition, we used tw
         o stickleback populations from different lineages: an eastern European linea
         ge with a more pelagic phenotype (Lake Constance) and a western European lin
         eage with a more benthic phenotype (Lake Geneva). We found that stickleback 
         caused trophic cascades in the pelagic but not the benthic food chain. Evide
         nce for pelagic trophic cascades was stronger in treatments where parasite l
         oad of stickleback was reduced with an antihelmintic medication, and where f
         ish originated from Lake Constance (i.e., the more pelagic lineage). A struc
         tural equation model revealed that differences in stickleback lineage and p
         arasite load were most likely to impact trophic cascades via changes in the 
         composition, rather than overall biomass, of zooplankton communities. Overal

         ss about the importance of distinguishing different movement patterns for un
         derstanding their specific impact on animal ecology and evolution. One speci
         fic form of movement is nomadism, where animals move between habitats in an 
         arrhythmic fashion. Although not yet described in detail for freshwater fish
         , nomadism between lakes within drainage systems could affect local lake foo
         d webs in an otherwise unpredictable fashion. In this study, we used passive
          telemetry to describe inter‐lake movements of 1,280 individually tagged a
         dult benthivorous bream (<em>Abramis brama</em>) over nine contiguous years 
         in a drainage system with two paired lakes. The movements can best be descri
         bed as partial nomadism, where a part of the population is neither resident 
         nor migratory, but instead moves between lakes in a variable, arrhythmic fas
         hion, often with long residency in one lake before moving to the other. We f
         ound extensive between‐year variation in the proportion and direction of b
         ream moving, with higher movement propensity being partly associated with lo
         wer somatic condition. Notably, movements out of lakes were significantly mo
         re in direction of the neighbouring lake than away from the paired lakes, su
         ggesting that at least direction was not random. Since bream are important e
         cosystem engineers, fluctuating densities of adult bream could affect ecolog

      description => protected'<em>Background</em>: Seasonal spatio-temporal variation in habitat quality a
         nd abiotic conditions leads to animals migrating between different environme
         nts around the world. Whereas mean population timing of migration is often f
         airly well understood, explanations for variation in migratory timing within
          populations are often lacking. Condition-dependent tradeoffs may be an unde
         rstudied mechanism that can explain this differential migration. While fixed
          condition-specific thresholds have been identified in earlier work on ontog
         enetic niche shifts, they are rare in differential migration, suggesting tha
         t thresholds in such systems can shift based on temporally variable environm
         ental conditions.<br /><em>Methods</em>: We introduced a model based on size
         -specific tradeoffs between migration and growth in seasonal environments. W
         e focused on optimal migratory timing for first-time migrants with no knowle
         dge of an alternative habitat, which is a crucial stage in the life history 
         of migratory salmonids. We predicted that optimal timing would occur when in
         dividuals move from their natal habitats based on a seasonally variable rati
         o of predation and growth. When the ratio becomes slightly more favorable in
          the alternative habitat, migratory movement can occur. As it keeps shifting
          throughout the season, the threshold for migration is variable, allowing sm
         aller individuals to move at later dates. We compared our model predictions 
         to empirical data on 3 years of migratory movement of more than 800 juvenile

         e downstream Nile basin. It has traditionally been assigned to the East Coas

         983; Roberts, 1975; Snoeks et al., 1997). This viewpoint has been challenged
          and inclusion of the Lake Victoria ichthyofauna into the Nilo-Sudan provinc
         e has been suggested (Lévêque, 1997; Witte et al., 2009). More recent biog
         eographic and genetic studies have revealed that Lake Victoria and the small

         fferentiation between and within lake populations of roach (<em>Rutilus ruti
         lus</em>) - a widespread and abundant cyprinid species ‐ in lakes in which
          salmonids have evolved endemic adaptive radiations. Based on more than 3,00
         0 polymorphic RADseq markers, we detected low but significant genetic differ
         entiation between roach populations of two ultraoligotrophic lakes and betwe
         en these and populations from other lakes. This, together with differentiati
         on in head morphology and stable isotope signatures, suggests evolutionary a
         nd ecological differentiation among some of our studied populations. Next, w
         e tested for intralacustrine diversification of roach within Lake Brienz, th
         e most pristine lake surveyed in this study. We found significant phenotypic
          evidence for ecological intralacustrine differentiation between roach caugh
         t over a muddy substrate and those caught over a rocky substrate. However, e
         vidence for intralacustrine genetic differentiation is at best subtle and ph
         enotypic changes may therefore be mostly plastic. Overall, our findings sugg
         est roach can differ between ecologically distinct lakes, but the extent of 
         intralacustrine ecological differentiation is weak, which contrasts with the
          strong differentiation among endemic species of whitefish in the same lakes

      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
