Scatter plots of 61 species (see Appendix) recognized by different groups of respondents. a Percentages of men versus women. b Percentages of people at Lake Nasser versus Allaqi Village. c Percentages of people <50 years versus ≥50 years. The solid line (X=Y) represents equal percentages: no differences between the subgroups. Not all 61 species are visible in these graphs because some points represent multiple species. For example, data point (100 %; 100 %) represents 9 species in each of the graphs, indicating all people in both locations recognize them

Percentages of species (total 61) recognized in Wadi Allaqi for different age classes. a the values of the recognition index, R s, for people at Lake Nasser and in Allaqi Village; b for men and women. The two upper graphs at the top in each box are based on Table 3 and refer to the total number of species that are recognized at least by one person in that specific age class; species not recognized by any person in a subset were omitted here and the number in the box represents the total number of species that are recognized. The error bars represent ±1 SEM. Non-parametric testing revealed that all differences are significant except for data point (30–40) in a
