Description Background and Aims: Abies vejarii (oyamel) is an endemic species of northeastern Mexico, currently listed as Near Threatened by the InternationalUnion for the Conservation of Nature (IUCN), with isolated populations. The objectives of the present study were i) to look for areas where the idealconditions for oyamel development meet, using the maximum entropy algorithm in the Sierra Madre Oriental (SMOR), ii) identify the topographic environmental variables associated with its current distribution, and iii) evaluate the current anthropogenic impacts on the distribution of A. vejarii.Methods: Using a species distribution model (MDE), the suitability of its habitat was modeled, with bioclimatic and topographic data. The environmental variables that influence its geographical distribution were identified through cluster (CA) and principal component analyses (PCA). Finally, the effect of the anthropogenic impact was linked with its current distribution areas.Key results: The total area that is predicted and that is climatically adequate for its presence was 67,096 ha. The analysis of the environmental and topographic variables showed that the annual temperature range and the precipitation of the driest month were the most important. A negative and significant association with the anthropogenic impact was found. The Sierra Madre Oriental presents the conditions that are the favorable habitat for the persistence of A. vejarii.Conclusions: The quantification of the optimal areas that allow the establishment and development of A. vejarii will make it possible to design strategies and prescribe actions for the conservation and restoration of populations of this species.
Antecedentes y Objetivos: Abies vejarii (oyamel) es una especie endémica del noreste de México, actualmente catalogada como Casi Amenazada por la Unión Internacional para la Conservación de la Naturaleza (UICN), con poblaciones aisladas. Los objetivos del presente estudio fueron i) buscar áreas en donde se reúnan las condiciones ideales para el desarrollo del oyamel utilizando el algoritmo de máxima entropía en la Sierra Madre Oriental (SMOR), ii) identificar las variables ambientales topográficas asociadas a su distribución actual y iii) evaluar los impactos antropogénicos actuales en la distribución de A. vejarii.
Métodos: Mediante un modelo de distribución de especie (MDE), se modeló la idoneidad de su hábitat, utilizando datos bioclimáticos y topográficos. Se identificaron las variables ambientales que influyen en su distribución geográfica mediante análisis cluster (CA) y de componentes principales (PCA). Finalmente, se relacionó el efecto del impacto antropogénico sobre sus áreas de distribución actual.
Resultados clave: El área total que se predice y que es climáticamente adecuada para su presencia es de 67,096 ha. El análisis de las variables ambientales y topográficas mostró que el rango anual de temperatura y la precipitación del mes más seco resultaron ser las más importantes. Se encontró una asociación negativa y significativa con el impacto antropogénico. La Sierra Madre Oriental presenta las condiciones que son el hábitat favorable para la persistencia de A. vejarii.
Conclusiones: La cuantificación de las áreas óptimas que permitan el establecimiento y desarrollo de A. vejarii hará posible diseñar estrategias y prescribir acciones para la conservación y restauración de las poblaciones de esta especie.
