Forest Fragments Surrounded by Sugar Cane Are More Inhospitable to Terrestrial Amphibian Abundance Than Fragments Surrounded by Pasture

Table 2

Observed species richness (𝑆_obs), estimated species richness (𝑆_est) for three estimators and efficiency (𝑆_obs/𝑆_est average) of terrestrial amphibians in the fragments of Semi-deciduous seasonal forest with two predominant matrix types (sugar cane and pastures).

Matrix	𝑆obs		𝑆est		Efficiency
		Chao 1	Chao 2	Bootstrap
Sugar cane	5	5.5	5.32	6	0.89
Pasture	4	4	4	4.25	0.97
