1.Which of the following statements about species-accumulation curves is TRUE? Only gamma diversity can be estimated using species-accumulation curves Species-accumulation curves are a technique to estimate alpha diversity of a relatively homogenous site Species richness will be estimated correctly using species-accumulation curves even if there are only a few samples The order in which samples are processed will not affect the precise shape of species-accumulation curve 2.
