The Effects of Pitfall Trap Spacing on Ant Richness (Hymenoptera: Formicidae), Abundance, and Composition in Dinder National Park, Sudan

Ants play an important role in Sudanese biodiversity and environmental impact assessments, Although baiting is easy cheap to implement, several considerations, such as the spacing among bait, can affect estimation of abundance richness ants species. In this study, we evaluated effects bait on number ant We also demonstrate which distance between baits showed best relationship costs species sampled. sampled 30 transects 100 m with ranging (2.5; 3.3; 5; 6.7; 10 20 m), spread over 1 km² into three different type ecosystems (Wooded grass land, Riverine ecosystem Maya ecosystem), at DNP located Sudan. The did not diversity estimative. Regardless spacing, collected every five was around 8, average approximately 50 individuals. However, per higher a larger gap baits. Transects spans captured 50% more than 2.5 3.4 apart. Our study suggest that most efficient sampling design using only park would be, place 450 m.
