  • Congenital feeding response to a novel prey in a Mexican gartersnake 
    MANJARREZ SILVA, FRANCISCO JAVIER; MACIAS GARCIA, CONSTANTINO DE JESUS; DRUMMOND DUREY, HUGH MICHAEL (PeerJ, 2020-03-05)
    In this study, we explored chemosensory, ingestive and prey-catching responses of neonate Mexican Black-bellied Gartersnakes (Thamnophis melanogaster) to crayfish (Cambarellus montezumae). By comparing snakes from a recently ...
  • Intraspecific variation in the diet of the Mexican garter snake Thamnophis eques 
    MANJARREZ SILVA, FRANCISCO JAVIER; PACHECO TINOCO, MARTHA SIC SIC; VENEGAS BARRERA, CRYSTIAN SADIEL (PeerJ, 2017-11-14)
    The Mexican Garter Snake (Thamnophis eques) is a terrestrial-aquatic generalist that feeds on both aquatic and terrestrial prey. We describe size-related variation and sexual variation in the diet of T. eques through ...
  • Microgeographic variation in body condition of three Mexican garter snakes in central Mexico 
    VALENCIA FLORES, ERIKA; VENEGAS BARRERA, CRYSTIAN SADIEL; FAJARDO GUADARRAMA, VICTOR MANUEL; MANJARREZ SILVA, FRANCISCO JAVIER (PeerJ, 2019-03-13)
    Background. Geographic variation in body size and condition can reveal differential local adaptation to resource availability or climatic factors. Body size and condition are related to fitness in garter snakes (Thamnophis), ...
  • Morphological convergence in a Mexican garter snake associated with the ingestion of a novel prey 
    MANJARREZ SILVA, FRANCISCO JAVIER; MACIAS GARCIA, CONSTANTINO DE JESUS; Drummond, Hugh (Ecology and Evolution., 2017-06-20)
    Morphological convergence is expected when organisms which differ in phenotype experience similar functional demands, which lead to similar associations between resource utilization and performance. To consume prey with ...
  • Present and future ecological niche modeling of garter snake species from the Trans-Mexican Volcanic Belt 
    GONZALEZ FERNANDEZ, ANDREA; MANJARREZ SILVA, FRANCISCO JAVIER; GARCIA VAZQUEZ, URI; D' ADDARIO, MARISTELLA; GARCIA AGUILAR, ARMANDO SUNNY (PeerJ, 2018-04-11)
    Land use and climate change are affecting the abundance and distribution of species. The Trans-Mexican Volcanic Belt (TMVB) is a very diverse region due to geological history, geographic position, and climate. It is also ...
  • Respuesta de la herpetofauna a la perturbación del hábitat: un análisis multiescalar 
    GONZALEZ FERNANDEZ, ANDREA (Universidad Autónoma del Estado de México, 2019-01-22)
    El cambio de uso de suelo y el cambio climático están amenazando el mantenimiento de la biodiversidad a nivel global. Estos cambios ambientales afectan negativamente parámetros poblacionales como la distribución, abundancia ...
  • Thamnophis eques (Mexican Garter Snake). Diet. 
    MARTINEZ VACA LEON, OCTAVIO IVAN; MANJARREZ SILVA, FRANCISCO JAVIER; MAYA GARCIA, SHERIDAN JAEL (Society for the Study of Amphibians and reptiles, 2021-03-15)
    On 27 September 2018 at 1651 h, we captured an adult male T. eques that regurgitated a partially digested mouse pup. Analysis of rodent guard hair shows a lanceolate pattern of cuticular scales that is characteristic of ...
