Foraging Activity and Trophic Spectrum of Red Ant Pogonomyrmex barbatus Smith, 1858, in Productivity-Contrasted Microenvironments

Table 3

Trophic niche breadth of Pogonomyrmex barbatus at two semiarid sites with contrasting productivities during the rainy and dry season. JR: Jardín rainy; JD: Jardín dry; LlR: Llano rainy; LlD: Llano dry.

Site-season	Levins standardized index	Shannon diversity index	𝑡 value and probability
JR	0.31	0.95
LlR	0.17	0.81	𝑡0.05(44) = 4.96, 𝑃<0.0001
JD	0.16	0.76
LlD	0.14	0.73	𝑡0.05(34) = 0.713, 𝑃=0.48
