Spanish abstract Estudios conducidos en Oklahoma durante tres años (2014-2017) proveen los datos extensivos de la posible presencia de la Texas kangaroo rat (Dipodomys elator), una especie considerado como Tier II que requiere la máxima atención para conservación en siete condados del suroeste de Oklahoma. El estudio incluyó 15 muestreos por 93 noches; 266 localidades distintas fueron muestreados con 9,094 trampa-noches y más de 32,428 km de caminos pavimentados y de tierra fueron examinados para el hábitat y actividad potencialmente. Ningún ejemplar de D. elator fue visto o capturado. Sin embargo, 2,178 individuos de 17 especies de mamíferos fueron colectados o observados. Nuevas localidad e información de la historia natural de las especies fue obtenida, se registran datos ejemplares o observaciones para seis condados. Los resultados de este estudio y datos históricos sugieren que el Texas kangaroo rat (D. elator) fue extirpado del estado de Oklahoma
English abstract Surveys conducted during three years (2014-2017) provide the most extensive documentation to date for the possible presence of the Texas kangaroo rat (Dipodomys elator), a Tier II species considered to be of greatest conservation need, in seven counties in southwestern Oklahoma. The project encompassed 15 surveys on 93 nights; 266 localities were surveyed for a total of 9,094 trap nights and more than 32,428 km of paved and unpaved roads were surveyed for potential habitat and activity. No Texas kangaroo rats were captured or observed. However, 2,178 individuals of 17 mammal species were captured and individuals of 12 additional mammal species were collected and/or observed. New locality and natural history information for mammal species was obtained and six county records were recorded based on specimens and/or observations. Project results and historical information suggest that the Texas kangaroo rat (D. elator) is likely extirpated from the state of Oklahoma
