“…Las madrigueras de la Parcela 3 fueron encontradas en vegetación arbustiva, donde la actividad humana y animales grandes se imposibilita, por lo que los armadillos tienen alimento y protección contra depredadores (Montero-Bagatella et al, 2017). Esto pudo haber contribuido a que en la Parcela 3, el IAR fuese mayor a pesar de que el esfuerzo de muestreo fue menor comparado con las demás parcelas; quizá debido a que la mayoría de los armadillos usó las madrigueras de forma consistente.…”

CARACTERIZACIÓN DE LA POBLACIÓN DE Dasypus novemcinctus Y FAUNA ASOCIADA A SUS MADRIGUERAS EN SONÁ, VERAGUAS, PANAMÁ

La evaluación de las poblaciones de armadillos en zonas perturbadas por asentamientos y ganadería, reciben poca importancia, lo que afecta el estado de conservación de la especie. En nuestro país no existen estudios sobre densidad poblacional, patrones de uso de madrigueras y comportamiento general en armadillos. Por ello, el presente estudio tuvo como objetivo caracterizar la población de armadillos Dasypus novemcinctus e inventariar las especies de vertebrados asociados a sus madrigueras, en una finca dedicada a la ganadería intensiva, en Soná, Veraguas, Panamá. Para la realización de esta investigación, se utilizó un método mixto de observación directa y cámaras trampa desde enero hasta junio de 2022. Se detectaron 47 armadillos y se determinó una densidad de 1.25 madrigueras/a y 0.38 ind/ha. Se registraron un total de 18 especies asociadas a las madrigueras de D. novemcinctus; nueve de aves, siete de mamíferos y dos de reptiles. Se presentan las primeras observaciones de Tamandúa mexicana, Procyon lotor y Conepatus semistriatus, los cuales no habían sido reportados en esta localidad. El presente estudio resalta la importancia de los armadillos como especie clave en ecosistemas, ya que por su actividad atraen múltiples especies, contribuyendo a mantener la biodiversidad; incluso en zonas intervenidas como fincas ganaderas.

“…Seven sites were sampled, differing mainly in their plant associations and the time they have been protected from livestock management (Figure 1). The composition of the vegetation was obtained from the study of Montero- Bagatella et al (2017). Site 1 was on a basalt flow with short grass pastures and sparse tussocks of Aristida harvadii and Sclerepogon brevifolius.…”

“…Hibernation occurs from the end of October to March, interrupted by short feeding periods (Valdez and Ceballos 2003;Castillo-Castillo 2009). These animals prefer to live in open treeless, shrubless areas with short grasses (Yensen and Sherman 2003;Hannon et al 2006;Montero-Bagatella et al 2017), though they have also been recorded in areas with shrubs and in crops (Best and Ceballos 1995;Mendoza-Carreón 2009). This species is facing conservation problems resulting from the intense development and extreme transformation of its habitat by humans, which has spared only 30 % of its original habitat (Sánchez-Cordero et al 2005).…”

Seasonality and changes in climate and habitat dynamics lead ground squirrels to use resources during the most favorable seasons and avoid less favorable conditions by hibernating. The Perote ground squirrel (Xerospermophilus perotensis) is nationally and internationally classified as vulnerable to extinction; however, our knowledge of this species is scant. The aim of this study was to describe and analyze its annual cycle. Temperature and rainfall data (2008 to 2014) for the area were used. Animal frequencies were obtained for seven sites by capture-markrecapture; captured animals were marked, and their sex, weight, age and reproductive status noted. Population structure was obtained for each site using the male:female sex ratio and age structure. Activity during the annual cycle is statistically associated with temperature. Scrotal males were most abundant while females with signs of pregnancy and those lactating were recorded least often. The number of adults and juveniles differed statistically, with adults more abundant throughout the study. Weight varied throughout the study, and differed between adults and juveniles. The Perote ground squirrel exhibits phenological patterns similar to those of species of the genus Spermophilus, which respond to changes in temperature and its activity cycle begins in spring and ends in autumn. The weight of the squirrels was dynamic, probably resulting from reproduction, hibernation and their response to changes in environmental resources. The frequency of this species was low, with few juveniles recorded, indicating that X. perotensis is facing serious problems, likely from severe anthropogenic pressure and its own ecological characteristics.

“…The habitat was a shrubland bordering a semi-stabilized dune and dominated by Larrea tridentata and Opuntia imbricata. The record of X. perotensis was a direct observation recorded and digitally photographed on 21th August 2013 near the town of San Antonio El Limón, Perote, Veracruz (19º 31' 05'' N, 97° 19' 40'' W), while conducting car trips searching for the species (Montero-Bagatella et al 2017, 2018.…”

Interaction between Ground Squirrels with rattlesnakes in arid zones

et al. 2020

View full text Add to dashboard Cite

The predation of ground squirrels by rattlesnakes has influenced the development of specialized anti-predatory strategies by squirrels. This note describes two cases of encounters of squirrels with rattlesnakes in México, captured photographically. The first event is the interaction between an individual of Xerospermophilus spilosoma and one of Crotalus atrox in the Mapimí Biosphere Reserve, Durango, an arid area of the Chihuahuan Desert in northern México. The second event involved two individuals of X. perotensis and one of C. scutulatus salvini in the Perote Valley, a semi-arid zone of Veracruz. Both squirrel species displayed anti-predation behaviors reported for the genus, as well as the ability to spot snakes and communicate the alert status to other group members; thus, these observations contributes to the knowledge of the natural history of these species.
