Description
Forty-five sampling sites across three latitudinal and three altitudinal gradients in the Upper Nazas River Basin, Mexico, provide data on tree species, structure, and biomass. The dataset, authored by Gabriel Graciano-Ávila and last updated in June 2026, includes census records for all trees with a DBH ≥ 7.5 cm. Thirty-seven species were identified, with Juniperus deppeana being the only species present across all gradients.
Use Cases
Modeling forest biomass based on altitude and tree species composition mentioned in the description
Analyzing beta diversity patterns across latitudinal and altitudinal gradients using Bray-Curtis similarity
Studying the influence of latitude-altitude interaction on tree diameter and height
Comparing species richness and Importance Value Index (IVI) across different environmental gradients
Strengths
Data covers 45 sampling sites (2500 m2 each) distributed across three latitudinal and three altitudinal gradients.
Analysis includes 37 identified tree species and calculates alpha diversity, beta diversity, Importance Value Index, and biomass.
Statistical analysis was performed using two-way ANOVA or aligned-ranges ANOVA with Tukey test (p < 0.05).
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The dataset's 999.0 KB size suggests a limited scope of observations.
