Seguimiento del Corechi (Tolypeutes matacus) por Medio de Carreteles de Hilo en el Chaco boliviano

Abstract

Resumen El corechi (Tolypeutes matacus) es una presa clave para los cazadores indígenas del Chaco boliviano y está categorizado como "Vulnerable" para el Libro Rojo de Bolivia (2009). Este estudio es parte de un programa más amplio que promueve el uso sostenible de la especie. Con el objetivo de describir el desplazade 33 corechis mediante un carrete con hilo adosado al caparazón de los ejemplares. En 17 animales se utilizó solo un carrete de 350 m porque el mismo se vació antes de que el animal terminara su desplazamiento nocturno, pudiéndose mapear el recorrido, pero no ubicar al animal para reponer el carrete. Una hembra y cuatro machos fueron seguidos durante cinco días y los demás individuos durante 2-4 días. La distancia máxima de seguimiento de un individuo fue de 1.650 m a lo largo de cinco días. Para cada ruta de 350 m, los individuos visitaron un promedio de cinco cuevas, 0,5 termiteros, realizaron seis escarbaduras y llevaron a cabo 19 eventos de alimentación. Durante la primera jornada de seguimiento el recorrido fue relativamente lineal. Sin embargo, al realizar seguimientos en días consecutivos, las rutas se volvieron sinuosas. No enconregistrados. La conservación debe priorizar vedas a favor de las hembras, programas de divulgación con niños y cazadores locales y áreas protegidas sin presión de cacería. Palabras clave: nido Spool-and-thread tracking of the three-banded armadillo Tolypeutes matacus in the Bolivian ChacoAbstract The three-banded armadillo Tolypeutes matacus is a key prey species for indigenous subsistence hunters in the Bolivian Chaco, and is categorized as Vulnerable by the 2009 Bolivia Red Book. This study is burrow / nest use, and feeding behavior, 33 three-banded armadillos were tracked using a spool-and-thread mechanism attached to their carapace. Seventeen animals were followed for a single 350 m spool of thread, because the spool often emptied of thread before the night's activity was complete, and the animal could not -tinuous days, and the other individuals for 2-4 days. The maximum distance tracked by thread was 1,650 m sites, 0.5 termite nests, and summed 19 feeding bouts. Single-spool tracks tended towards linearity, whereas and males or between juveniles and adults for any of these behavioral aspects. Conservation must focus on male-biased harvests, environmental education with local children and hunters, and protected areas with no hunting.

“…A spool-and-thread study of T. matacus in the Chaco provided information on daily displacement, burrow and nest use, and feeding behavior (Noss, 2013). The method provided a maximum of five days of tracking, and the 350 m daily thread was frequently fully drawn out or broken in a single day.…”

“…In addition to its regional significance, this species is also of global interest because it is held in at least 113 zoos in Asia, Europe, North America and South America ( International Species Information System, 2016 ). In contrast to other armadillos it does not have subterranean habits, using burrows abandoned by other species or hiding in dense vegetation ( Redford and Eisenberg, 1992 , Cuéllar, 2002 , Noss, 2013 ). When individuals of this species are threatened, they can roll their body into a ball, an exclusive feature of the genus Tolypeutes ( Meritt, 2008 ).…”
