Figure 89 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 89: Reconstruction of the maximum glacial extent during the high point of the last ice-age (26 – 20 thousand years ago). Figure adapted from the publication Geologische Bundesanstalt (Hrsg.) (2013): Der Alpenraum zum Höhepunkt der letzten Eiszeit – Posterkarte. Geologische Bundesanstalt, Wien.
Figure 90 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 90: Representation of the seasonal cycle of stratification and mixing in a dimictic lake throughout a year.
Figure 88 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 88: Water temperature in lakes of the Po river catchment (orange) were generally warmer than in lakes of the Rhone (green) and Rhine (red) catchments. The lakes on the northern edge of the Alps remain cooler in summer and the lakes in the south remain warmer in winter. Upper panel shows 95 % quartile and lower panel shows 5% quartile of monthly mean lake surface water temperatures based on remote sensing (Advanced Very High Resolution Radiometer; 1989 – 2014 [214]). Quar- tiles were used rather than true minimum/maximum to avoid the effects of outliers.
Figure 85 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 85: Histograms showing variation in lake surface area (left column), lake maximum depth (middle column) and height above sea level (altitude; right column) among the major catchments.
Figure 84 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 84: Distance among lakes by river in the Rhine (upper panel), Rhone (middle panel) and Po (lower panel) river catchments.
Figure 81 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 81: Depth distribution of fish weight (biomass per unit effort) in pelagic habitats to 50 m deep according to deep-set vertical nets (fish in the 3 m of net close to the lake floor were excluded).
Figure 82 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 82: Factors explaining differences in the fish species composition among pairs of lakes within each catchment. No clear driver of fish community composition emerged in the Rhone catchment. In the Rhine catchment, the distance between the lakes along rivers, as well as differences in altitude, explained differences in the species composition between lakes. Al- titude explained differences in fish species composition among lakes in the Po catchment (also when Poschiavo was excluded).
Figure 79 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 79: Proportion of non-native species by deep-set vertical nets among lakes. Native species are represented in grey. Upper panel shows proportion by abundance, lower panel proportion by biomass. The high relative biomass of this species in Upper Upper is one 7.5 kg fish.
Figure 83 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 83: The uniqueness of the lake fish community relative to the number of recorded native fish species (shown in left panel of Figure 25) compared with different apects of the lakes. Only the relationship for maximum total phosphorus was significant (R2 = 0.248, p = 0.013), and negative. Note that the horizontal axis of the plots of maximum depth, total phosphorus and maximum total phosphorus is displayed on a log scale. Lake surface area has been square-root transformed.
Figure 80 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 80: Depth distribution of fish weight (biomass per unit effort) in benthic habitats to 50 m deep according to CEN benthic nets.
Figure 77 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 77: Proportion of non-native species in benthic habitats shown by benthic CEN nets among lakes. Native species are represented in grey. Upper panel shows proportion by abundance, lower panel proportion by biomass. Note that the high relative abundance and biomass of Salmo trutta in Poschiavo is uncertain. These were mainly juvenile trout that could not be confidently identified to species and were assumed to be S. trutta for the purpose of this comparison.
Figure 87 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 87: The surface waters of lakes closer to sea level (lower altitude) were warmer in the cooler months (left), while the surface waters of higher elevation lakes tended to be cooler in the warmer months (right). Smaller lakes also tended to be cooler in winter (data not shown). Monthly mean lake surface water temperatures based on remote sensing (Advanced Very High Resolution Radiometer; 1989 – 2014 [214]). The 5% quartiles were used to avoid the effects of outliers.
Figure 78 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 78: Proportion of non-native species in open-water habitat shown by pelagic CEN nets among lakes. Native species are represented in grey. Upper panel shows proportion by abundance, lower panel proportion by biomass. Note only four fish were caught in pelagic CEN nets in Idro (three of which were Salmo trutta). Note also that the high relative abundance and biomass of Salmo trutta in Poschiavo is uncertain. These were mainly juvenile trout that could not be confidently identified to species and were assumed to be S. trutta for the purpose of this comparison.
Figure 76 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 76: Proportion of non-native species in the littoral habitat shown by shallow-set vertical nets. Native species are represented in grey. Note that the very high relative abundance and biomass of Salmo trutta in Poschiavo is uncertain. These were mainly juvenile trout that could not be confidently identified to species and were assumed to be S. trutta for the purpose of this comparison.
Figure 70 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 70: Composition of fish catches among lakes in the littoral zone by electrofishing (excluding streams and rivers). Note that the high relative biomass of Esox lucius in Rousses was caused by one large fish. The high biomass of Tinca tinca in Remoray was also caused by only three large individuals. Finally, the high abundance of Alburnus alburnus in Lucerne was caused by one action with 171 individuals.
Figure 75 in Diversity, distribution and community composition of fish in perialpine lakes – "Projet Lac" synthesis report
Figure 75: Proportion of non-native species in the littoral shown by electrofishing. Native species are represented in grey. Upper panel shows proportion by abundance, lower panel proportion by biomass. Note that the high relative abundance and biomass of Salmo trutta in Poschiavo is uncertain. These were mainly juvenile trout that could not be confidently identified to species and were assumed to be S. trutta for the purpose of this comparison.
