Its distribution range is restricted to New Mexico and Texas, in the United States of America, and northern Chihuahua, in México. The Médanos de Samalayuca Flora and Fauna Protection Area (MSFFPA) is located in northern Chihuahua. Different economic activities are carried out in this region, mainly irrigated crops of pecans (Carya illinoinensis). Populations of G. arenarius have been recorded within these areas. Therefore, the objective of this work was to define the extent of the trophic niche and the changes in the physical condition of G. arenarius in a ranch within the MSFFPA over three contrasting seasons (dry, wet, and post-wet). Forty G. arenarius specimens were collected from Arantxa Ranch. Morphometric measurements and the weight of collected individuals were recorded, and the digestive tract was removed to prepare histological slides. Seven 25 m²-quadrants were established, and the species of the vegetation cover were recorded and collected for reference. The Seasonal Fitness Index (IK) and Levin&#8217;s Niche Breadth Index were calculated. Males had higher average measurements and weight than females. The IK was 2.82 ± 0.47 in males and 2.64 ± 0.61 in females. Significant differences in the IK between seasons were only found in females. The correlation between IK and plant cover was strong for males and females. The diet mainly comprised Physalis hederifolia, Dimorphocarpa wislizeni, and Cenchrus incertus. Levin&#8217;s index showed that G. arenarius is a specialist rodent. Sexual dimorphism was evident, with males larger than females. The physical condition index of gophers is influenced by resource availability. In other studies, this parameter has been related to changes in food availability. It has been reported that gophers tend to feed mainly on crops; however, pecan cultivation was not a major element in the diet of the desert pocket gopher, as it feeds on the vegetation associated with crops. Gophers are considered generalists; nonetheless, the present study showed that G. arenarius is a specialist, although this may be a consequence of anthropogenic activities.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: La tuza arenera (Geomys arenarius) es un roedor herbívoro fosorial perteneciente a la familia Geomyidae. Tiene una distribución restringida a Nuevo México y Texas en los Estados Unidos de América y en México al norte de Chihuahua. En el Área de Protección de Flora y Fauna Médanos de Samalayuca (APFFMS), que se ubica al norte de Chihuahua, se realizan diferentes actividades económicas destacando el cultivo por riego de nuez de pecán (Carya illinoinensis). Dentro de estas zonas de cultivo se han registrado poblaciones de G. arenarius. Por lo cual, el objetivo del presente trabajo es definir la amplitud de nicho trófico y cambios en la condición física de G. arenarius en un rancho dentro del APFFMS en tres temporadas (seca, húmeda y posthúmeda) con diferentes grados de humedad. Se obtuvieron un total de 40 ejemplares de G. arenarius del Rancho Arantxa, se registraron las medidas morfométricas y el peso, se extrajo el tracto digestivo para la elaboración de laminillas microhistológicas. Se establecieron siete cuadrantes de 25 m² donde se registró la cobertura de las especies vegetales y se colectó el material botánico para elaborar material de referencia. Se calculó el índice de condición física y el índice de amplitud de nicho de Levins. El promedio de las medidas y peso de los machos fue mayor al de las hembras. El IK en machos fue de 2.82 ± 0.47 y en hembras de 2.64 ± 0.61, no se detectaron diferencias estadísticamente significativas en el IK de los machos por temporada y se detectaron diferencias estadísticamente significativas en el IK por temporada en hembras. La correlación entre el IK y la cobertura para los machos y hembras fue fuerte. La dieta estuvo conformada principalmente por Physalis hederifolia, Dimorphocarpa wislizeni y Cenchrus incertus. El índice de Levins evidenció que G. arenarius es un roedor especialista. El dimorfismo sexual fue evidente al ser los machos de mayor talla que las hembras. El índice de condición física de las tuzas se ve influenciada por la disponibilidad de recursos en otros estudios se ha relacionado este parámetro con cambios en la disponibilidad de alimento. Se ha reportado que las tuzas suelen alimentarse principalmente de los cultivos, aunque para la tuza arenera, el cultivo de nogal no representó un elemento importante en la dieta y ésta se alimentó de la vegetación asociada a la parcela agrícola. Las tuzas son consideradas generalistas, sin embargo, en el presente estudio G. arenarius evidenció ser especialista, aunque este podría ser efecto de las actividades antropogénicas.]]></p></abstract>
