| description | Background and Aims: Eco-anatomical studies enable the estimation of the response of taxa to different environmental factors. Considering the biological and ecological relevance of the genus Mimosa, the adaptive possible responses of two endemic Mexican taxa were estimated, M. aculeaticarpa var. aculeaticarpa y M. luisana, through the eco-anatomical analysis of their wood, in order to evaluate their resistance and tolerance to changes in precipitation.Methods: Three trees of similar size and coverage per taxon, were collected. Wood cubes of 1 × 1 cm were cut and softened by boiling. Transverse, tangential and radial sections, 20 µm in thickness were made. Samples were stained with fast safranin-green and mounted in synthetic resin. The description and the analysis of anatomical wood features were based on the nomenclature proposed by the IAWA.Key results: Mimosa aculeaticarpa var. aculeaticarpa presents ring-porosity, while M. luisana is characterized by diffuse porosity. Mimosa aculeaticarpa var. aculeaticarpa shows vessels with medium tangential diameter in early-wood, and small ones in late-wood, whereas M. luisana presents vessels with small tangential diameter. Both have simple perforation plates, bordered, alternate and small intervessel pits, and vestured ones in M. luisana. Mimosa aculeaticarpa var. aculeaticarpa mainly has axial paratracheal vasicentric parenchyma, while in M. luisana, it is vasicentric and unilateral. In M. aculeaticarpa var. aculeaticarpa, rays are uniseriate, and in M. luisana, they are biseriate. Fibers are of short length, fine diameter and thick wall. The highest indexes of vulnerability (VI) and of mesomorphy (MI) were found in M. aculeaticarpa var. aculeaticarpa (4.05 y 729.05, respectively), indicating that this taxon is the most vulnerable to drought, while the lowest values of both VI and MI corresponded to M. luisana (1.42 and 226.71, respectively), suggesting that this taxon is more resistant to drought.Conclusions: It is proposed that M. aculeaticarpa var. aculeaticarpa is suitable for restoring mesic sites and M. luisana for dry environments. |

Antecedentes y Objetivos: Los estudios ecoanatómicos permiten estimar la respuesta de los taxa a distintos factores ambientales. Considerando la relevancia biológica y ecológica del género Mimosa, se estimaron las posibles respuestas adaptativas de dos taxa endémicos de México, M. aculeaticarpa var. aculeaticarpa y M. luisana, a través de un análisis ecoanatómico de su madera, para evaluar su resistencia y tolerancia a cambios en la precipitación.Métodos: Se recolectaron tres árboles de talla y cobertura similar por taxon. Se cortaron cubos de madera de 1 × 1 cm, ablandados a reflujo. Se hicieron secciones transversales, tangenciales y radiales, con grosor de 20 µm. Se tiñeron con safranina-verde rápido y se montaron en resina sintética. La descripción y el análisis de los caracteres anatómicos de la madera se basaron en la nomenclatura propuesta por la IAWA.Resultados clave: Mimosa aculeaticarpa var. aculeaticarpa presenta porosidad anular, mientras que M. luisana tiene porosidad difusa. Mimosa aculeaticarpa var. aculeaticarpa muestra vasos con diámetro tangencial mediano en madera temprana y pequeño en madera tardía y M. luisana presenta vasos con diámetro tangencial pequeño. Ambos tienen placa de perforación simple, punteaduras intervasculares areoladas, alternas y pequeñas, y ornamentadas en M. luisana. Mimosa aculeaticarpa var. aculeaticarpa posee principalmente parénquima axial paratraqueal vasicéntrico, mientras que en M. luisana es vasicéntrico y unilateral. En M. aculeaticarpa var. aculeaticarpa, los radios son uniseriados y en M. luisana biseriados. Las fibras son de longitud corta, diámetro fino y pared gruesa. Los índices de vulnerabilidad (IV) y de mesomorfía (IM) más altos se encontraron en M. aculeaticarpa var. aculeaticarpa (4.05 y 729.05, respectivamente), lo que indica que este taxon es más vulnerable a la sequía, mientras que los valores más bajos de IV y de IM correspondieron a M. luisana (1.42 y 226.71, respectivamente), sugiriendo que éste es más resistente a la sequía.Conclusiones: Se propone que M. aculeaticarpa var. aculeaticarpa es apta para restaurar lugares mésicos y M. luisana lo es para ambientes secos.
