Data and code from: Effects of prescribed fire on plant α- and ꞵ-diversity and the regulating role of soil in a mesquite-oak savanna

This dataset supports spatial ecological analysis of plant diversity
patterns in response to fire disturbance within a mesquite-oak savanna
ecosystem. The dataset comprises 288 systematically collected quadrat
samples (1-m²) stratified across three soil series types (TA: 120
quadrats, VaB: 120 quadrats, KaB: 48 quadrats) with pre-fire
(September-December 2018) and post-fire (September-December 2019) temporal
comparisons. Each observation includes spatial coordinates, binary fire
treatment status, and comprehensive diversity metrics encompassing three
alpha diversity measures (Shannon diversity, species richness, and
evenness) and six beta diversity indices, including both incidence-based
measures (Sørensen dissimilarity and its turnover and nestedness
components) and abundance-based measures (Bray-Curtis dissimilarity and
its balanced variation and abundance gradient components).
