Background and Aims: Ecological niche models have been used to understand how species can change or persist in an environmental and geographical space over time.

| description | Background and Aims: Ecological niche models have been used to understand how species can change or persist in an environmental and geographical space over time. The aims of the study were i) to model the ecological niche of Pinus montezumae and Pinus pseudostrobus in Mexico, ii) to evaluate and compare the similarity and equivalence of niche suitability between the distribution areas of both species, and iii) to propose potential geographic zones for the delimitation of seed-producing and conservation areas for each species.Methods: We used geographical data on distribution of species and climatic, topographic, elevation and soil data as environmental predictors, which were modeled based on the Maximum Entropy algorithm. The parameters of similarity (I) and equivalence (D) were estimated to know the degree of overlap of the niche of the species. For the selection of seed areas, environmental data were used that defined the distribution of each species and dasometrics of the National Forest and Soil Inventory (INFyS).Key results: The models show that the two species have similar areas of high suitability, distributed in the Trans-Mexican Volcanic Belt and the Sierra Madre del Sur. The highest contribution to the models for Pinus pseudostrobus were the variables average annual temperature (41.3%) and total annual rainfall (14.3%), whereas the soil (31.1%) and altitude (29%) were determinants in P. montezumae. The niche overlap analysis indicates that the observed value of equivalence (D=0.430) is less than the similarity value (I=0.610), suggesting that the species have a similar niche but that this is not equivalent, which could be in the process of diversification.Conclusions: The suitability of the ecological niche is similar for the two pine species, but it is not equivalent as they present differential environmental variables. These results have implications for the selection of potential areas for seed production and conservation of each species. |

Antecedentes y Objetivos: Los modelos de nicho ecológico se han usado para entender de qué manera las especies pueden cambiar o persistir en un espacio ambiental y geográfico a lo largo del tiempo. Los objetivos del presente estudio fueron i) modelar el nicho ecológico de P. montezumae y P. pseudostrobus en México, ii) evaluar y comparar la similaridad y equivalencia de la idoneidad del nicho entre las áreas de distribución de las dos especies, y iii) proponer zonas geográficas potenciales para la delimitación de áreas productoras de semillas y conservación para cada especie.Métodos: Se usaron datos geográficos para predecir la distribución de especies y climáticos topográficos y edáficos como predictores ambientales, fueron modelados con base en el algoritmo de Máxima Entropía. Se estimaron parámetros de similaridad (I) y equivalencia (D) para conocer el grado de traslape del nicho. Para la selección de áreas semilleras se usaron los datos ambientales que definieron la distribución de cada especie y dasométricos del Inventario Nacional Forestal y de Suelos (INFyS).Resultados clave: Los modelos muestran que las dos especies presentan zonas muy similares de alta idoneidad, distribuidas en la Faja Volcánica Transmexicana y en la Sierra Madre del Sur. Las mayores contribuciones al modelo de Pinus pseudostrobus fueron las variables temperatura promedio anual (41.3%) y precipitación total anual (14.3%), mientras que el suelo (31.1%) y la altitud (29%) fueron determinantes para el modelo de P. montezumae. El traslape de nicho presenta un valor observado de equivalencia (D=0.430) menor al de similaridad (I=0.610), sugiriendo que las especies tienen un nicho similar, pero que este no es equivalente en su totalidad, el cual podría estar en proceso de diversificación.Conclusiones: La idoneidad del nicho ecológico es similar para las dos especies de pino, pero no es equivalente al presentar variables ambientales diferenciales. Estos resultados tienen implicaciones para la selección potencial de áreas productoras de semillas y conservación para cada especie.
