Figs. 32–34. Trap efficiency. 32 in The Dung- and Carrion-Feeding Scarabs (Coleoptera: Scarabaeoidea) of an Amazonian Blackwater Rainforest: Results of a Continuous, 56-Week, Baited-PitfallTrap Study

Figs. 32–34. Trap efficiency. 32) Quantity. Light-colored bars represent realized number of scarabaeoids taken in each trap expressed as a mean percentage for the bait type and preservative compared to the expected catch (= the mean percentage of all traps with that bait type and preservative (100%)). Dark-colored bars represent realized number of scarabaeoids taken in each trap expressed as a mean percentage for bait type only compared to the expected catch (the mean percentage of all traps with that bait type (100%)) if all variables between traps were equal. Nearly all of the traps performed well with the exceptions of traps 3 and 15 (dung) and 19 and 20 (carrion); 33) Species richness. Light-colored bars represent realized number of scarabaeoid species taken in each trap expressed as a mean percentage for the bait type and preservative compared to the expected catch. Dark-colored bars represent realized number of species taken in each trap expressed as a mean percentage for bait type only compared to the expected catch if all variables between traps were equal. Nearly all of the traps performed equally well; 34) Richness of only the "common" scarabaeoid species. Light-colored bars represent realized number of "common species" (those in excess of 0.005% of the total number of individuals) taken in each trap expressed as a mean percentage for the bait type and preservative compared to the expected catch. Dark-colored bars represent realized number of "common species" taken in each trap expressed as a mean percentage for only the bait type compared to the expected catch if all variables between traps were equal. Nearly all of the traps performed equally well in capturing the "common species".
