Bat survey of the lower Juruena River and five new records for the state of Mato Grosso, Brazil

Abstract

The northern Brazilian state of Mato Grosso is considered an important biogeographical region, but has many sampling gaps. Apart from the well-documented non volant mammal community in the region, the bat fauna still poorly recorded. The aim of this study was to record the bat species of Juruena National Park, northern Mato Grosso, Brazil. Nineteen sites were sampled using mist-nets placed at ground level and near potential bat roosts. We collected 115 individuals belonging to 35 species and five families, which increased the number of species known for Mato Grosso´s Amazon from 86 to 91. The five new records were: Peropteryx kappleri, Peropteryx leucoptera, Lonchorhina inusitata, Tonatia saurophila, and Artibeus concolor. Our results pointed out the necessity of more studies in order to better estimate the bat diversity in northern Mato Grosso.

Assessing the distribution of a species‐rich group in a continental‐sized megadiverse country: Bats in Brazil

“…This validation is a critical point of SDMs (Rebelo & Jones, ; West, Kumar, Brown, Stohlgren, & Bromberg, ), especially for areas outside the known species' geographical range (Elith et al, ; Randin et al, ) or areas with species occurrence gaps due to lower environmental representativeness, as we presume to be the case of the northern of Mato Grosso state (Figure , cells I9‐12 to L9‐12), whose lower species richness is very likely an artefact. In fact, recent data confirm that this region has higher number of species than predicted by our models (Dalponte et al, ; Miranda et al, ). Such observation reinforces the need for inventories in the region, as well as the in situ validation of any SDM.…”

“…The spatial and taxonomic bias found here is supported by new acoustic studies in Brazil (Hintze, Barbier, & Bernard, ) and reinforces the clear under sampled characteristic of the Brazilian bat fauna, with large knowledge gaps (Bernard et al, ). Therefore, besides some progresses (Barros et al, ; Dalponte, Gregorin, Esteves‐Costa, Rocha, & Marcelino, ; Miranda, Zago, Carvalho, Rubio, & Bernardi, ), our analysis still suggests that none of the Brazilian biomes can be considered well surveyed for bats (see also Varzinczak, Bernardi, & Passos, ).…”

Vertical stratification in bat assemblages of the Atlantic Forest of south-eastern Brazil

“…Indeed understorey roost selection may increase the chances of captures of several bat species in ground level mist-nets, including species of gleaner insectivore phylostomids, and aerial insectivore emballonurids and thyropterids that use ground hollows, termite hollows and fallen trunks (Dalponte et al . 2016, Simmons & Voss 1998, Voss et al . 2016).…”

New records on the use of man-made constructions as diurnal roosts by bats from the southern Amazon in central Brazil

“…Instead, there was a colony of more than 50 Pteronotus parnellii Gray, 1843 individuals, a Mormoopidae bat species (Figures 2B and 2C). (Miranda et al 2015) and Juruena National Park (Dalponte et al 2016), respectively; 4 and 5: the first formal record of T. cirrhosus for the Cerrado of the Mato Grosso State at the Nova Xavantina municipality (Sousa et al 2013) and the recent record of this species for the Chapada dos Guimarães National Park (Lima et al in press), respectively. For details, see the main text.…”

“…In spite of being considered of broad geographical distribution, the first formal record of this species for the Mato Grosso State took place only in 2013 (Sousa et al 2013). Since then, its geographical distribution has been extended to new localities in this state (Miranda et al 2015;Dalponte et al 2016;Lima et al in press). Together with Miranda et al (2015), the occurrence of T. cirrhosus between Porto Alegre do Norte and Confresa municipalities is the southernmost record of this species for the Amazon, a distance of roughly 500 km east of the record at the Medium Teles Pires River.…”
