Répteis do Mato Grosso do Sul, Brasil

Abstract

ABSTRACT. Reptiles of Mato Grosso do Sul, Brazil. Data is presented on richness and composition of reptiles from the state of Mato Grosso do Sul (MS), based on reviews of publications, examination of scientifi c collections and unpublished fi eld data provided by researchers. We recorded 188 species distributed in eight species of Testudines, three Crocodylia and 177 Squamata (16 amphisbaenians, 48 lizards and 113 snakes). Thirteen species have restricted distributions within the state, 13 are restricted to the state and nine are in the process of being described. The diversity of the MS reptiles, even if underestimated, accounts for 25% of the species known to occur in Brazil. The plateau presents 176 species, of which 30% are restricted to this location, while 131 species (6% exclusive) occur in the fl oodplain. The Cerrado is the richest domain in species, although it is the region with the highest sampling gap in the state. The most well-known section is the Midwest MS, which includes the Pantanal. About 40% of the species of reptiles of MS are widely distributed, occurring in at least fi ve of the seven Brazilian domains. The reptiles of MS are more similar to those of the Chaco, probably because the chacoan fauna is very similar to that of the Pantanal, which includes better inventoried portions of MS. Although the Cerrado is the predominant domain in the state, the fact of being poorly sampled justifi es the lower similarity of reptiles from this domain with those of MS, when compared with those of Chaco. Overall, the MS reptile fauna shows greater similarity to that found along the diagonal of open formations of South America. Only 18% of species were assessed by IUCN, which reinforces the need for an assessment of the conservation status of MS reptile species. The north, south and east of the state have not being adequately sampled, which is of concern since these sections have seen signifi cant anthropogenic alteration. For this reason, these areas, especially the north -including the headwaters of rivers which supply the fl oodplain -are indicated as priorities for the completion of inventories of reptiles and creation of areas to protect them.KEYWORDS.

A compilação de dados foi baseada em publicações, coleções científi cas e dados disponibilizados por pesquisadores. Foram registradas 188 espécies distribuídas em oito espécies de Testudines, três Crocodylia e 177 Squamata (16 anfi sbenas, 48 sáurios e 113 serpentes). Treze espécies, dentro do estado, possuem distribuição restrita, 13 não são encontradas em outros estados brasileiros e nove estão em processo de descrição. A riqueza de répteis do MS, mesmo que subestimada, corresponde a 25% das espécies conhecidas no Brasil. No planalto estão presentes 176 espécies, das quais 30% foram registradas somente neste local, enquanto que na planície de inundação ocorr...

Roadkill records of reptiles and birds in Cerrado and Pantanal landscapes

“…Richness and abundance. The 29 species of reptiles identified here represent 15% of reptile richness (188 species), and the 47 species of birds represent 7% of the avifauna (630 species) previously reported for Mato Grosso do Sul (Ferreira et al 2017, Nunes et al 2017. The richness estimated for road-killed reptiles supports a more complete sample in PAN and CER than in the transitional landscapes of the ECO and URU, where it is likely that several other road-killed species were not recorded.…”

“…3). Previously, this species has only been reported in the Cerrado plateaus and Amazon rainforest (Murta-Fonseca et al 2015, Ferreira et al 2017. Eight reptile species were recorded as roadkill for the first time in Brazil (new roadkill records, NRR): Hydrodynastes bicinctus, Amerotyphlops brongersmianus, Bothrops mat- Bearded Toadhead Turtles are easily recognizable, despite doubts about subspecies occurrence within the geoffroanus complex (Souza 2005).…”

“…Hydrodynastes bicinctus has only been reported in open areas of the Cerrado plateaus and Amazon rainforest (Murta-Fonseca et al 2015). In Mato Grosso do Sul, H. bicinctus was only reported in the municipalities of Bataguassu, Ivinhema, Paraíso das Águas, Três Lagoas, and Santa Rita do Pardo (Murta-Fonseca et al 2015), while the reptile checklist from the state (Ferreira et al 2017), which included areas near the BR-262 between Campo Grande and Corumbá, did not make any record of this species.…”

“…First records. Based on the most recent reptile checklist from Mato Grosso do Sul (Ferreira et al 2017), which encompasses a broad inventory of the Pantanal and sur-rounding plateaus, our record of Hydrodynastes bicinctus (Dipsadidae) in the Pantanal basin is the first geographic record (FGR) for this species (Table 2). Hydrodynastes bicinctus has only been reported in open areas of the Cerrado plateaus and Amazon rainforest (Murta-Fonseca et al 2015).…”

“…Recent efforts have been made to update fauna checklists in Mato Grosso do Sul, where most records are con-centrated in particular geographic regions (Cáceres et al 2008, Fischer et al 2015, Ferreira et al 2017, Nunes et al 2017, Tomas et al 2017. Large scale spatiotemporal monitoring of regional fauna has provided information about species distribution within different environments, as well as for the Cerrado and Pantanal domains (e.g.…”
