“…We also included data from road-kills (Plate 3a) and poaching by local people, reported voluntarily during occasional visits to farms (Plate 3b). We compared our findings with those of previous studies (Martinelli et al, 2014; Araújo et al, 2015; Chiarello et al, 2015; Estrela et al, 2015; Gomes et al, 2015; Rocha et al, 2015; Fig. 1).…”

“…Protected areas on the border of Minas Gerais and Espirito Santo states are considered the last stronghold for P. maximus in the Atlantic Forest (Srbek-Araujo et al, 2009) but our findings indicate that the species is still present in Atlantic Forest remnants within the basins of the Paranaíba and Araguari rivers. In addition, a record from Vale do Encantado Private Natural Heritage Reserve in the municipality of Uberaba (Minas Gerais) expands the southern range of the species (Martinelli et al, 2014; Fig. 1).…”

Studies on threatened species in highly modified and unprotected landscapes are necessary for the development of appropriate conservation policies. This is particularly important for species with large home ranges, such as the giant armadillo Priodontes maximus, whose occurrence in anthropogenic landscapes is poorly known despite its categorization as Vulnerable on the IUCN Red List. We searched and surveyed for the giant armadillo within human-modified areas in central Brazil using direct and indirect methods across a wide region dominated by diverse farming environments and scattered remnants of natural vegetation. During a 14-year period (2003–2016), we located 54 records of the species, including three road-kills and two instances of poaching. Most of the occurrence points (83%) were in native vegetation, with 17% in anthropogenic environments (pastures and roads). We confirmed the presence of the giant armadillo within a wide, intensely human-altered region. These findings indicate that Cerrado and Atlantic Forest remnants in modified landscapes in central Brazil play an important role as refuges for this armadillo species. In addition to habitat loss, road-kills and poaching persist as threats to the giant armadillo. Conservation actions are necessary to minimize human impacts and facilitate the persistence of the giant armadillo in this region. Policies that both deter illegal deforestation and strengthen incentives for the protection of natural vegetation remnants and restoration of biological corridors such as gallery forests would aid conservation of the giant armadillo in this area.

“…The species is able to remain inside burrows for several consecutive days (Carter & Encarnac ßão, 1983;Leite-Pitman et al, 2004;Silveira et al, 2009). Individuals of P. maximus frequently dig their burrows underneath termite's nests and anthills (Carter & Encarnac ßão, 1983;Silveira et al, 2009;Desbiez & Kluyber, 2013;Martinelli et al, 2014) and it is even suspected that they might feed on them while inside burrows during daytime. However, our accelerometer data shows that armadillos present almost no movement while inside burrows, ruling out the hypothesis of daytime underground feeding.…”

Methods for the characterization of activity patterns in elusive species: the giant armadillo in the Brazilian Pantanal

The behavioral study of elusive species, which often cannot be directly observed in the wild, is based on the use of animal monitoring technologies. Here, we evaluate the performance of four methods applied simultaneously on a single population to detect and characterize the activity behavior of elusive species, using the giant armadillo Priodontes maximus as a model. GPS tagging, accelerometer, and camera trap array data were used to characterize general activity patterns, while camera traps placed in front of burrows in use were used to define activity duration, onset, and termination times. Circular kernel probability density functions were used to characterize activity patterns with each data set and the overlap coefficient D4 was used to characterize the similarity between them. We gathered data from 53 armadillos during 9 years in the Pantanal wetlands of Brazil. Activity duration estimates showed significant variation among monitoring methods but were generally short (4.5-6 h on average). Overall, the estimates of activity timing provided by the methods used were relatively similar (>75% D4 overlap) and pointed to a nocturnal activity pattern. Armadillos left their burrows mainly in the first hours after sunset, and terminated their activity mainly between midnight and 4 AM. However, the camera trap array provided a later activity onset and peak estimates for the species when compared to other methods. The species spends 75-80% of its time underground and accelerometer data shows that armadillos are not active and do not feed while underground, pointing to a fossorial behavior for the species. Although researchers should be aware of the small biases that can emerge from some of the methods, the general similarities among patterns indicates that researchers can choose among the ever-increasing number of animal monitoring technologies depending on their research question and constraints.
