Occurrence of Cabassous tatouay (Cingulata, Dasypodidae) in Rio Grande do Sul and its potential distribution in southern Brazil

Abstract

ABSTRACT. Cabossous tatouay Desmarest, 1804 is considered a rare species in southern South America, and Rio Grande do Sul State, Brazil, records of the species are scarce and inaccurate. This study reports 40 localities for C. tatouay, and provides a map of the species' potential distribution using ecological niche modeling (ENM). The ENM indicated that in this region C. tatouay is associated with open grasslands, including the areas of "Pampas" and the open fields in the highlands of the Atlantic Forest. This study contributes to the information about the greater naked-tailed armadillo in southern Brazil, and provides data key to its future conservation.

OCCURRENCE AND PREDICTIVE DISTRIBUTION OF Crypturellus noctivagus (AVES, TINAMIDAE) IN BRAZIL

“…Data from scientific collections/museums were not used in this study, because we considered them as historical records of C. noctivagus. Records were assembled, considering the exact or approximated location, by using high resolution satellite images from Google Earth, in geographic coordinates (latitude/longitude), in decimal degrees, Datum WGS-84 (Oliveira et al 2015, Sabattini et al 2017. Duplicate records were excluded (Oliveira et al 2017.…”

“…Among several predictive models, the MaxEnt (Maximum Entropy) algorithm allows to correlate the species occurrence to bioclimatic variables, and predict areas of environmental suitability for the species , Soberón 2007, Philips & Dudik 2008, Olivero et al 2016. It is also possible to insert environmental variables in the prediction, such as topography, forest vegetation (Rajão et al 2010, Oliveira et al 2015 and land use (Santos et al 2017).…”

“…Paulo, Paraíba, Pernambuco, Ceará, Piauí, Pará, and Mato Grosso do Sul (Ubaid et al, 2010;Gonzalez & Abba, 2014;. Moreover, the species is reported from the Atlantic forest, Caatinga, Cerrado savanna, and Pampa biomes (Feijó & Langguth, 2013;Anacleto et al, 2015;Oliveira et al, 2015). The occurrence of C. tatouay in the Pantanal wetland was predicted by some authors (Anacleto et al, 2006;Paglia et al, 2012;.…”

“…The species of the genus Cabassous are still poorly known, especially C. tatouay (Ubaid et al, 2010;Superina et al, 2014). Field records of C. tatouay are rare and may be false due to external morphological similarities with other species of the genus (Oliveira et al, 2015;Massocato & Desbiez, 2017;Desbiez et al, 2018;. Cabassous tatouay is a cryptic, solitary species with a specialist insectivorous diet (Redford, 1985;Anacleto, 2007).…”

“…It is believed that C. tatouay can use both forested and open areas, but prefers forested habitats (Gonzalez & Abba, 2014;. Others report that it uses primary and secondary forest habitats, but is rare in areas that are largely degraded or with agricultural activities (Mikich & Bérnils, 2004;Anacleto, 2006;Aguiar & Fonseca, 2008;Oliveira et al, 2015).…”
