Habitat characterization of Amoreuxia wrightii (Bixaceae), a species of Northeastern Mexico at risk
Background and Aims: In Mexico, Amoreuxia wrightii is endangered according to NOM-059-SEMARNAT-2010. In this study the characterization of natural populations of A. wrightii, which grow in two contrasting communities taking into account the canopy cover in the Tamaulipan thornscrub in northeastern M...

| description | Background and Aims: In Mexico, Amoreuxia wrightii is endangered according to NOM-059-SEMARNAT-2010. In this study the characterization of natural populations of A. wrightii, which grow in two contrasting communities taking into account the canopy cover in the Tamaulipan thornscrub in northeastern Mexico, was performed by analysis of associated flora and physical and chemical properties of soils.Methods: In 2014, 10 sampling sites were established in two environments differentiated by vegetation structure: five sites in plant associations with dense vegetation cover and five sites in disturbed areas with bare soil. In each area the vegetation structure and edaphic variables were evaluated and a Canonical Correspondence Analysis was performed.Key results: According to the relationship with other species, A. wrightii was associated with pioneer species that emerge after disturbance, dominated by grasses like Aristida purpurea, Cenchrus ciliaris, Cynodon dactylon, Panicum obtusum, herbs such as Gutierrezia sarothrae, Gymnosperma glutinosum and Parthenium hysterophorus, and low shrubs like Acacia amentacea, A. berlandieri and Eysenhardtia texana. According to edaphic variables, it was observed that A. wrightii preferred clayey and silty soils, soils with slightly alkaline pH and high bulk density. No individual of A. wrightii was recorded at sites that had soils with high sand content and high content of organic matter.Conclusions: Amoreuxia wrightii was more abundant in areas with no coverage, devoid of vegetation, soils low in organic matter and high in pH, silt, clay and bulk density. According to the relationship with other species, it was associated with pioneer species, which emerge after a disturbance. |

Antecedentes y Objetivos: En México, Amoreuxia wrightii se encuentra en estatus de peligro de extinción de acuerdo a la NOM-059-SEMARNAT-2010. En este estudio se realizó la caracterización de poblaciones naturales de A. wrightii, mediante un análisis de la flora asociada y las propiedades físicas y químicas de los suelos donde se desarrollan en dos comunidades contrastadas desde el punto de vista de la cobertura del dosel en el matorral tamaulipeco en el noreste de México.Métodos: En 2014 se establecieron 10 sitios de muestreo en dos ambientes diferenciados por la estructura de la vegetación: cinco sitios en asociaciones vegetales con cobertura vegetal densa y cinco sitios en áreas perturbadas con suelo desnudo. En cada área se evaluó la estructura vegetal y variables edáficas y se realizó un Análisis de Correspondencia Canónica.Resultados clave: De acuerdo a la relación con otras especies, A. wrightii se asoció con especies pioneras, que emergen después de un disturbio, con el dominio de pastos como Aristida purpurea, Cenchrus ciliaris, Cynodon dactylon, Panicum obtusum, especies de herbáceas Gutierrezia sarothrae, Gymnosperma glutinosum y Parthenium hysterophorus, así como arbustos de porte bajo como Acacia amentacea, A. berlandieri y Eysenhardtia texana. De acuerdo con las variables edáficas, se observó que A. wrightii prefiere suelos arcillosos y limosos, con suelos con pH ligeramente alcalinos y con densidad aparente alta. Ningún individuo de A. wrightii fue registrado en sitios que presentaron suelos con altos contenidos de arena y altos contenidos de materia orgánica.Conclusiones: Amoreuxia wrightii fue más abundante en áreas con nula cobertura, desprovistas de vegetación, sobre suelos con bajo contenido de materia orgánica y altos contenidos de pH, limo, arcilla y densidad aparente. De acuerdo a la relación con otras especies, se asoció con especies pioneras, que emergen después de un disturbio.
