Questions 1.      Using the Shannon Wiener diversity index results, which habitat was more diverse? Suggest reasons for the differences in species diversity in the habitats you sampled.(5) 2.      Why do we measure biodiversity in the first place? Example what are some advantages of knowing biodiversity indices? What can we use this information for?(4) 3.      What does the Shannon Wiener diversity index actually tell us? Explain this in your own words. 4.      What is the species richness in the two communities?(2) 5.      Are there any differences and similarities in the species composition between the two communities? (Point out these differences or similarities and suggest reasons to explain the difference if any). 6.      To do: calculate the species composition similarity index between the two communities using the jaccard’s index formula   species composition species abundace WOODY Dipcadi glaucum 1 Acacia melfera 19 Cenchrus ciliaris 32 Talinum mcoffrium 8 Stripagrotis hitgluma 92 Albizia anthelmintica 1 Schmiditia pappophoroides 7 160 NONWOODY Sorghum bicolon subsb arandinacem 59 Urochloa brachyuran 21 Eragrostis echinochloidea 14 Acacia nigrescens 5 Commicarpus pentandrus 26 Phyllanthus maderaspatensis 17 Cenchrus ciliars 70 Ocimum americanum 105 Hebenstretia integrifolia 9 A. anthelmintica 1 Calestephane divaricate 79 Platycarpha carlinoides 10 Pseudographalium undulatum 37 453?
