| description | Environmental conditions influence several ecological and phenological processes of plant species, such as dispersal, seed bank in the soil, and germination. The objective of the present study was to analyze the relationship between the abundance of adult individuals and seedlings, seed rainfall, germination rate, and survival of Abies hickelii regarding environmental conditions in the Sierra Norte Oaxaca, Mexico. We conducted vegetation sampling, placed traps for seed rain, collected seed banks in the soil, and quantified germination and survival. At each site, we measured environmental conditions (climatic, edaphic, topographic, and light). It was recorded that at the highest altitude site (3150 m), A. hickelii had a higher density of adults and seedlings and a higher percentage of germination compared to the lower altitude sites. The abundance of adult individuals and seedlings of A. hickelii is related to canopy openness and maximum rainfall intensity. Seed production is related to total annual precipitation, while germination and survival were not associated with any of the environmental variables analyzed. This study considered different aspects of the A. hickelii life cycle and its relationship with the environmental conditions where it was established, which allowed us to determine the most significant environmental variables in each growth stage. The results represent relevant information for endemic and endangered species. |

Las condiciones ambientales influyen en varios procesos ecológicos y fenológicos de las especies vegetales, como la dispersión, el banco de semillas en el suelo y la germinación. El objetivo del presente estudio fue analizar la relación entre la abundancia de los individuos adultos y plántulas, la lluvia de semillas, la tasa de germinación y la supervivencia de Abies hickelii, con respecto a las condiciones ambientales en la Sierra Norte, Oaxaca, México. Se realizaron muestreos de vegetación, se colocaron trampas para la lluvia de semillas, se colectó el banco de semillas en el suelo y se cuantificó la germinación y su supervivencia. En cada sitio se midieron las condiciones ambientales (climáticas, edáficas, topográficas y lumínicas). Se registró que en el sitio de mayor altitud (3150 m), A. hickelii presentó mayor densidad de adultos y plántulas, y mayor porcentaje de germinación en comparación con los sitios de menor altitud. La abundancia de individuos adultos y plántulas de A. hickelii está relacionada con la apertura del dosel y la intensidad máxima de precipitación. La producción de semillas está relacionada con la precipitación total anual; mientras que la germinación y la supervivencia no se asociaron con ninguna de las variables ambientales analizadas. Este estudio consideró diferentes aspectos del ciclo de vida de A. hickelii y su relación con las condiciones del medio donde se establece, para conocer las variables ambientales más relevantes en cada etapa de su crecimiento. Esta información es relevante para especies endémicas y en peligro de extinción.
