“…Remarks: Although sparse, Matses information about Cabassous unicinctus includes a few novel observations, notably that this species travels underground as well as on the surface. 1 The nocturnal activity reported by the Matses agrees with other rainforest observations (Emmons, 1997), but not with the diurnal activity reported from Brazilian savanna habitats (Bonato et al, 2008). The perpendicular orientation of burrows attributed to this species by the Matses is consistent with quantitative data on burrow characteristics summarized by Trovati (2015).…”

“…The burrows excavated by armadillos, which are used for sleeping, nesting, escaping predators, thermoregulation, or creating an insect reservoir, are dug in welldrained soils or into ant and termite mounds Loughry 2003, 2008). Nonetheless, in the same study area, Bonato et al (2008) obtained inverse values regarding the density of individual armadillos, estimated using a mark-recapture method, showing 0.26 individuals/ha for C. unicinctus and 0.14 individuals/ha for E. sexcinctus. Probably, the higher density of E. sexcinctus burrows is related to the behavior of digging more burrows compared to C. unicinctus, and not with its abundance (density), which could be explained by the fact that the latter armadillo species is more fossorial (Wetzel 1980).…”

“…The species that dig their own burrows produce ones with peculiar shapes and sizes (Srbek-Araujo et al 2009;Ceresoli and Fernandez-Duque 2012), a fact that is related to the anatomical differences (present in the osteology, muscle, and myology) (Vizcaíno et al 1999;Koneval 2003) and morphological characteristics (weight, size, carapace format and members) of these animals (Marinho-Filho et al 1998;Medri et al 2011). Bonato et al (2008) recorded in the Itirapina Ecological Station (Estação Ecológica de Itirapina (EEI)) four species of armadillos: C. unicinctus, D. novemcinctus, D. septemcinctus, and E. sexcinctus. They observed that the Dasypus occur at a low population density.…”

“…Other differences are in the diet, E. sexcinctus is omnivorous, feeding on vegetal material (plants, roots and fruits, invertebrates, vertebrates, and carrion (Dalponte and Tavares-Filho 2004;Vaz et al 2012). While C. unicinctus is insectivorous, the diet of these consists of more than 90 % arthropods (chiefly ants and termites) (Bonato et al 2008), but acarina and isoptera are also found (Anacleto 2007).…”

Background: Signs left by some mammals such as tracks, trails, burrows, scratches, feces, hair, and others can be an important tool for species identification. This study was conducted in the Itirapina Ecological Station, in the southern Brazilian Cerrado, whose main objectives were to (1) compare the burrow morphometric variables of Cabassous unicinctus and Euphractus sexcinctus and (2) check for differences in the occurrence of foraging burrows in two different environments: areas with vegetation (shrubby grassland) and areas without vegetation (roads). The collected measures of armadillo's burrows have been width, height, depth, and angle relative to the soil. To record foraging burrows (<70 cm), the linear transect methodology was used simultaneously in roads and shrubby grassland environments. Results: In a shrubby grassland environment of the Itirapina Ecological Station, a density of 121 burrows/ha pertaining to C. unicinctus and of 277 to E. sexcinctus was observed. Although there is overlap between them, morphometric variables were used to measure the burrows; significant differences were observed in all: depth, p < 0.001; ratio, p < 0.001; perimeter of the ellipse (perimeter), p < 0.001; and angle of excavation relative to the soil, p < 0.001. There was an observed interaction between the variables p < 0.001 for Wilk test. The PCA analysis evidenced two highly distinct groups of burrows, which corresponded to the initial visual classification. The variance explained by axes 1 and 2 was 83.18 %. The variable that most influenced the distinction of the burrows of the species was the perimeter. There was a density of 114 foraging burrows/ha across the roads and 42 in shrubby grassland. The results of the ANOVA, p < 0.05, and Tukey test, p < 0.05, demonstrate significant difference between the mean densities of foraging burrows in the said environments. This indicates that armadillos use the area devoid of vegetation to feed. Conclusions: Thus, this study provides information that can assist in the surveys of these species as well as to clarify aspects of its ecology in the Cerrado.

“…The large overlap in the range of these taxa is possible due to the great diversity of habits, ranging from fossorial to arboreal species and from carnivorous-omnivorous to insectivorous food habits (Redford, 1985a). Also, they are able to occupy a wide range of habitats, from dryland to tropical rainforest (Wetzel, 1982;Bonato et al, 2008). Data on the biology and ecology of these taxa, mostly on their foods habits, are yet scarce (McDonough & Loughry, 2008).…”
