| description | Background and Aims: In Oaxaca, Mexico, 26 species of the genus Mammillaria are reported, seven of them being endemic. Mammillaria deherdtiana subsp. dodsonii is listed as threatened. The objectives of this paper were to describe the demographic, reproductive and ethnobotanical aspects of its use, as well as the floristic and bioclimatic aspects of the studied localities.Methods: In January 2015, two localities of Mammillaria deherdtiana subsp. dodsonii were found in the Sierra Norte. Between January and March, five transects of 5 m2 were located in one of them, in which the number of individuals was recorded, size categories were established, and the population structure was obtained. For the flowering process, ten flowers were chosen, and the perianth diameter was recorded every two hours. The vascular plants surrounding the sampled site were recorded and data on climatic variables were obtained. The inhabitants were interviewed to document the local knowledge and uses of this cactus.Key results: The population structure is multimodal. Juvenile individuals make up 65% and reproductive adults 33% in the studied locality. Anthesis lasts seven hours; dichogamy and hercogamy were observed, indicating a xenogamous breeding system. The subspecies is recognized with names in Spanish and Zapotec and is occasionally used as food, medicine, and ornament. Fifteen species belonging to the Pinus and Abies forest were recorded. The environmental preferences of the subspecies are temperatures of 9.6-12.7 °C, and precipitation of 1009-1405 mm.Conclusions: The xenogamous breeding system is worrisome due to the observation of just one floral visitor. The presence of bristles and radial spines in this subspecies suggests morphophysiological adaptations to cold. It is advisable to delve into the presence and effectiveness of pollinators and the recruitment dynamics of the subspecies. |

Antecedentes y Objetivos: En Oaxaca, México, se reportan 26 especies del género Mammillaria; siete de ellas endémicas. Mammillaria deherdtiana subsp. dodsonii está catalogada como amenazada. Los objetivos del trabajo fueron describir las características demográficas, reproductivas y aspectos etnobotánicos de su uso, así como los aspectos florísticos y bioclimáticos de las localidades estudiadas. Métodos: En enero de 2015 se encontraron dos localidades de Mammillaria deherdtiana subsp. dodsonii en la Sierra Norte. Entre enero y marzo se ubicaron cinco transectos de 5 m2 en una de ellas, en los cuales se registró el número de individuos, se establecieron categorías de tamaño y se obtuvo la estructura poblacional. Para la marcha floral se eligieron diez flores y cada dos horas se registró el diámetro de la apertura del perianto. Se registraron las especies de plantas vasculares que crecían cerca de ella y se obtuvieron datos de las variables climáticas. Se entrevistó a los pobladores para documentar el conocimiento y uso que le dan a esta cactácea.Resultados clave: La estructura poblacional es multimodal. Los individuos juveniles conforman 65% y los adultos reproductivos 33% en la localidad estudiada. La antesis dura siete horas; se observó dicogamia y hercogamia, lo cual indica un sistema de cruza xenógamo. La subespecie es reconocida con nombres en español y zapoteco y es usada de manera ocasional como alimento, medicina y ornamento. Se registraron 15 especies pertenecientes al bosque de Pinus y Abies. Las preferencias ambientales de la subespecie son temperaturas de 9.6-12.7 °C y precipitación de 1009-1405 mm.Conclusiones: El sistema de cruza xenógamo resulta preocupante por la observación de un solo visitante floral. La presencia de cerdas y espinas radiales sugiere adaptaciones morfofisiológicas de esta subespecie al frío. Se sugiere profundizar en la presencia y efectividad de los polinizadores y en la dinámica de reclutamiento de la subespecie.
