3.4 The effect of trap features on their evenness
Table 4 shows a significant difference between the number of individuals
captured from each species. Trap types did not affect the species
richness of the trapped scorpions. Also, as shown in Figures 1 to 4, the
most trapped specimens belong to the Buthacus tadmorensis while
the least belong to Odontobuthus bidentatus (Chi2 = 71.171, d.f.
= 3, P < 0.001).
From Table 4 and Figures 1 and 5, it can be seen that there is a
significant difference in the number of specimens caught in March, April
and May. The results show that the highest number of individuals was
caught in May compared to the other two months for all four species
(Chi2 = 130.691, d.f. = 2, P < 0.001).
As can be seen from Figures 2, 5 and 9 and Table 4, significantly more
animals were captured with covered traps than with open traps (Chi2 =
679.819, d.f. = 1, P < 0.001).
The total number of captures per species increased with increasing trap
diameter. Of the traps with two different diameters, the large traps
captured significantly more individuals of each species than the small
traps (Table 4 and Figures 3, 6 and 8) (Chi2 = 37.647, d.f. = 1, P
< 0.001).
Although cup traps, compared to funnel traps, captured more individuals
(Figures 4 and 7), according to Table 4, the differences between these
two trap types were not significant (Chi2 = 0.259, d.f. = 1, P = 0.611).
In conclusion, the total number of captures of the four scorpion species
increased with increasing trap diameter and when utilising covered cup
traps.
