Cladocerans (Crustacea, Anomopoda and Ctenopoda) from Cerrado of Central Brazil: Inventory of phytophilous community in natural wetlands

Abstract

Abstract:The aim of this study was to inventory the cladoceran fauna in wetlands located in two large areas that protect fragments of Cerrado. Located in the Brasília National Park-DF and Campo de Instrução de Formosa-GO, these wetlands are formed by upwelling groundwater, with extensive vegetation cover. We found 24 species in the Brasília National Park and 30 in the Campo de Instrução de Formosa. The observed richness reached approximately 80% of the estimated values for both protected areas. Moreover, the community of cladocerans in the kind of environment studied appears to be influenced by depth, with higher values of richness and similarity in wetlands of higher average depths. However, shallow wetlands contributed to the total richness with exclusive species, which shows the importance of these habitats for species richness.

First record of the endemic phytophilous cladoceran Celsinotum candango Sinev & Elmoor-Loureiro, 2010, in Minas Gerais state, in a threatened shallow lake at Serra do Gandarela

“…In Brazil, C. laticaudatum had only been found in the Northern part of the Brazilian Amazon (Smirnov & Santos-Silva 1995), while C. candango had only been found in the Brazilian Cerrado (Sinev & ElmoorLoureiro 2010, Sousa 2013). This paper now presents the first record of C. candango in the state of Minas Gerais and, furthermore, its first record in an altitudinal temporary lake on ironstone outcrops.…”

“…So far, there is only one more record of the species, also in a shallow pond from the Cerrado wetlands (Sousa et al 2013). In our study, we describe the presence of this species in a temporary shallow lake, ''Lagoa dos Coutos'' (Lake Coutos), located in ironstone outcrops at Serra do Gandarela (southern portion of the Espinhac¸o mountain range).…”

Composition and diversity of phytophilous cladocerans of oxbow lakes of Southwest Amazonian, Acre state, Brazil

“…The Chydoridae, Macrothricidae and the species Simocephalus latirostris Stingelin, 1906 frequently appear in association with macrophytes (e.g., Guntzel et al 2010 andSousa et al 2013) and are referred to as typically limnetic. However, in our study they were mostly found at an accessory frequency (except for Ephemeroporus hybridus and Leydigiopsis ornata).…”

A revision of the genus Disparalona (Cladocera, Chydorinae) in South America

“…Disparalona (M.) leptorhyncha is an endemic species, with distribution limited to South America. This species occurs from Paraguay to the Brazilian Amazon (Daday 1905;Smirnov 1996aSmirnov , 1996bVan Damme & Dummont 2010;Sousa et al 2013;Debastiani-Júnior et al 2015;Elmoor-Loureiro 2017). Disparalona (M.) leptorhyncha is very common in reservoirs, floodplain environments, ponds, and shallow lakes.…”
