| description | Background and Aims: Agave angustifolia, or chelem, is the only wild species of the Yucatán Peninsula and is the ancestor of cultivated species with great economic and cultural values. It provides important environmental services such as food source for fauna, it fixes sandy soils and sequesters carbon in arid habitats with poor soils. It is a potential crop that may face the dryness exacerbation expected for the region and the genetic erosion of henequen. The aim of this work is to gather data about its population density, spatial pattern, size structure, and the relationship between its abundance and environmental factors of the Yucatán coastal scrublands, in order to assess the use of the species for ecological restauration purposes.Methods: Field work was carried out in three coastal sites: Chuburná (Ch), San Benito, (SB) and Río Lagartos (RL). Thirty six 4 m2 plots were placed in SB and RL; we estimated the relative cover of Agave angustifolia, shrubs higher than 1 m and litter in each plot. Potential of Hidrogen (pH), electric conductivity, total nitrogen, organic matter and bright index were measured from the soil samples collected. Population density, spatial pattern and size structure of A. angustifolia in SB and Ch were also described.Key results: The cover of Agave angustifolia is negatively correlated to the shrubs and litter cover, as well as the amount of organic matter. The population density was lower than 0.1 individuals/m2, small individuals dominated the population structure and the spatial pattern is aggregated.Conclusions: Because its ability to live in poor soils, high temperatures and solar radiation, the species could be used to restore some ecological functions in the most arid habitats of the coast where the vegetation has been severily damaged. |

Antecedentes y Objetivos: Agave angustifolia, o chelem, es el único maguey silvestre de la Península de Yucatán y es el ancestro de especies domesticadas de gran valor económico y cultural. Presta importantes servicios ambientales como recurso alimenticio para la fauna, fijación de suelos arenosos y captura de carbono en ambientes áridos con suelos pobres. Es un cultivo potencial de cara al aumento de las sequías predichas para la región y del empobrecimiento genético del henequén. El objetivo de este trabajo es recabar datos sobre la densidad de sus poblaciones, su patrón espacial, estructura poblacional y la relación entre su abundancia y los factores ambientales en el matorral costero de Yucatán, con el fin de evaluar su uso en la restauración ecológica.Métodos: Se muestrearon tres localidades costeras: Chuburná (Ch), San Benito (SB) y Río Lagartos (RL). En SB y RL se trazaron 36 cuadrantes de 4 m2; dentro de cada uno se estimó el porcentaje de cobertura de Agave angustifolia, el de los arbustos de más de 1 m de alto y la cobertura de mantillo. Se tomaron muestras de suelo a las que se analizó pH, conductividad eléctrica, nitrógeno total, materia orgánica e escala de gris. Se describieron la densidad poblacional, distribución espacial y estructura por tamaños de A. angustifolia en SB y Ch.Resultados clave: La cobertura de Agave angustifolia se correlaciona negativamente con la cobertura de arbustos y mantillo, y cantidad de materia orgánica. Las densidades de su población fueron inferiores a 0.1 individuos/m2, hubo una mayor proporción de plántulas y su distribución espacial es agregada.Conclusiones: Al soportar suelos pobres, altas temperaturas y radiación solar, la especie puede servir para restaurar algunas funciones ecológicas en las zonas más áridas de la costa donde la vegetación ha sido severamente dañada.
