Structure and floristic composition of the savannahs of the Nizanda region, Isthmus of Tehuantepec (Oaxaca), Mexico ; Estructura y composición florística de las sabanas de la región de Nizanda, Istmo de Tehuantepec (Oaxaca), México

Current knowledge about savanna vegetation in Mexico is still incomplete, and it is dominated by an ongoing debate over their natural versus anthropogenic origin. In this paper we provide a detailed structural and floristic description of the savannas of the Nizanda region (Oaxaca, S Mexico). Vegetation was sampled in 20 sites of 15 m2 each (totaling 300 m2). A total of 135 morphospecies were encountered, 86 of which could be determined to species level; they were distributed in 29 families and 68 genera. Leguminosae, Poaceae and Asteraceae were the families with the largest taxonomic richness... Mehr ...
