Figure 21. Whisker plots of the Pielou’s Evenness Index J’, Shannon Index H’, Simpson’s Diversity Index, number of total species S and number of total individuals N. All are in dependence of the daytime (1: during day; 2: during night). Means are shown and confidence interval is given with +/- 95 (in Total Individuals N the Standard Error is given).

3.5. Biogeography In Figure 22 – Figure 25 horizontal Distribution and abundance of larvae is shown. The larvae are arranged due to their origin and spawning habitat as noted in Table 7. The habitats of origin are summarized as neritic, oceanic (epi – to deep pelagic), neritic to bathydemersal species and benthopelagic species. All cruises (La Bocaina 11/97, ECOS 04/99, Mesopelagic 05/99, Pelagic 01/00, Pelagic 11/00 and La Bocaina 03/02) are combined in the illustrations. The different colours and sizes of the circles indicate the numbers of larvae, which are listed in the legend within the maps. The isobaths are labelled, so that the horizontal Distribution is comparable with the bottom depths as well. The occurrence of fish larvae is clearly not restricted to the neritic habitat (Figure 22). A neritic – oceanic exchange takes place. A high abundance of neritic fish larvae occurs within the 100 m isobath or close to it. But many small groups of neritic larvae occur deeper than the 500 m isobath, especially southwest of Gran Canary and southeast of Fuerteventura. Some neritic larvae were found at oceanic stations with a bottom depth of about 2000 m, north of Gran Canaria and east of Fuerteventura.
