Altitudinal distribution of alpha, beta, and gamma diversity of pseudoscorpions (Arachnida) in Oaxaca, Mexico

摘要: Abstract In this study, we describe the spatial and temporal variation in diversity of pseudoscorpions along an altitudinal gradient Santiago Comaltepec, Oaxaca, Mexico. Four levels were selected (150, 989, 2177, 2990 m a.s.l.). Species recorded through monthly sampling from April 2016 to 2017. Alpha beta diversities estimated at every altitude, gamma was calculated for entire gradient; then related temperature precipitation. The highest species richness observed 989 m a.s.l. lowest months with number specimens January, March, April. Shannon index value (H′ = 1.724) 2177 m (H′ = 0.692). Gamma 2.15 mainly affected by average alpha diversity. higher during dry season slightly regulated Moreover, replacement than wet season, which associated changes temperature. Overall, increase decreases.
