Checklist das aves do Estado do Mato Grosso do Sul, Brasil

Abstract

ABSTRACT. Checklist of the birds of the state of Mato Grosso do Sul, Brazil. Contrasting with several other Brazilian states, just recently the state of Mato Grosso do Sul started to organize an inventory of its birdlife. We list 630 species of birds for the Mato Grosso do Sul, belonging to 26 orders and 74 families, representing 34% of birds occurring in Brazil. About 90% of these species have documented records of its occurrence in the state (Main List), according to proposed by CBRO. The others species still wait for adequate supporting documentation (Secondary List). Forty fi ve species were excluded for the Main List and included in Tertiary List due to problems in supporting documentation and/or incompatible distribution. The variety of landscapes and vegetation types under the infl uence of the biomes Cerrado, Pantanal, Atlantic forest, Chaco and Bosque Chiquitano is partly responsible for the high species diversity in Mato Grosso do Sul. However, several of these landscapes have been suppressed and/or severely altered by pastures, agriculture (mostly monocultures of sugar cane and soybeans) and agroforestry (Pinus and Eucalyptus). Thirty-eight species of birds occurring in the state were present on red lists at the global and/or national level. There are still large gaps in knowledge about the avifauna of Mato Grosso do Sul, mainly in the region of Paiaguás in the Pantanal wetlands and in neighboring regions with the state of Goiás, Paraguay (Chaco) and Bolivia (Bosque Chiquitano).

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.…”

“…Furthermore, it is notable that 83 Eunectes notaeus and 4 Dracaena paraguayensis were road-killed at reproductive ages (Table 2); such mortality could negatively impact their population sizes. For bird species, the most recent checklist does not classify species occurrences by macroregions in Mato Grosso do Sul (Nunes et al 2017), so we found no first geographical records, but we did record 12 new species of road-killed birds in Brazil. Large aquatic birds like Jabiru mycteria and Aramus guarauna, as well as small ones like Aramides cajaneus, Jacana jacana, and Chloroceryle americana are quite unusual road-killed species.…”

“…The most abundant road-killed species were those that use the environments provided by the creation of the road, such as roadside vegetation and marginal water ponds (Fischer 1997). Assuming that detection and removal rates did not vary among zones, the high number of reptiles and birds in PAN and URU zones would confirm the high abundance and richness of both groups in the Pantanal basin (De Souza et al 2014, Ferreira et al 2017, Nunes et al 2017). On the other hand, the low relative abundance of individuals in CER and ECO could be related to the environmental features in these regions, which are less preserved than the Pantanal floodplain region (Casella 2010).…”

“…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.…”

“…Além disso, também são observados remanescentes de Mata Atlântica no sul e leste do estado (Godoi et al 2013), manchas de floresta seca, também conhecidas como Florestas Chiquitanas, no extremo noroeste, na divisa com a Bolívia (Godoi & Souza 2016), e de Chaco no extremo oeste, na divisa com o Paraguai (Straube et al 2006). Devido à grande extensão territorial e presença de diferentes domínios biogeográficos, o Mato Grosso do Sul apresenta alta riqueza de espécies de aves, com ao menos 630 espécies pertencentes a 26 ordens e 74 famílias (Nunes et al 2017), o que corresponde a aproximadamente 33% das 1919 espécies de aves do Brasil (Piacentini et al 2015).…”
