Cladocerans (Crustacea: Anomopoda and Ctenopoda) of the Sempre Vivas National Park, Espinhaço Range, Minas Gerais, Brazil

Abstract

Protected areas are designed to maintain environmental conditions that favor the occurrence of a wide variety of taxa. However, few studies have devoted attention to inventories of biota in these areas. In this study, we provide a checklist of cladocerans for the poorly studied Sempre Vivas National Park, Minas Gerais state. Samples were collected in lotic and lentic environments, with a total of 27 species being recorded and the highest contribution coming from the Chydoridae family (21 spp.). Minas Gerais state is widely studied in relation to cladoceran fauna; nevertheless, the results indicate three new records. The genus Monospilus was reported for the first time in the Neotropical region.

Tropical Amphi-Pacific disjunctions in the Cladocera (Crustacea: Branchiopoda)

“…The sister genus, Miralona, is included in the map (Australia). Distribution points for Miralona after Sinev (2004a) and for the four Neotropical species after records by Sars (1901), Daday (1905), Brehm (1937), Valdivia Villar (1984), Vasquez (1986a, 1986b), Smirnov (1988) Rocha et al (2011), and Rocha Sousa and Elmoor-Loureiro (2013). For L. pulchra n.…”

Identification key for the Brazilian species and subspecies of the family Ilyocryptidae (Crustacea, Branchiopoda, Anomopoda)

“…Although I. sarsi also has a broad distribution, there are few records of this species in Brazil (Fig. 3) (Sousa et al, 2010;Sousa & Elmoor-Loureiro, 2013).…”

“…Even though information on the cladocerans of Brazil is mainly provided by one book (Elmoor-Loureiro, 1997), which is the touchstone for the accumulated knowledge of Neotropical cladocerans, specific information leading to the stability of the Ilyocryptidae in Brazil was only obtained after the revision of the family published by Kotov & Elmoor-Loureiro (2008). After this publication, new studies reported an increase in the geographical range of some species and the inclusion of new taxa into the Brazilian cladoceran fauna (Sousa et al, 2010;Sousa & Elmoor-Loureiro, 2011, 2012, 2013. In this context, it is important to construct an identification key that incorporates all these changes reported for the Brazilian cladocer- an fauna, and this comprises the main goal of this study.…”

Spatial and temporal dynamics of the mesozooplankton (Crustacea: Cladocera, Copepoda and Decapoda) in a Pampean shallow hyposaline lake during drought conditions

“…Shallow lakes biota is usually highly diverse due to a more extensive littoral zone (Wetzel, 1999). Nevertheless, the reduction of the lake area by drought conditions could lead to a decrease of the different habitat choices and refuge for mesozooplankton, possibly promoting a detrimental decline in species richness (Rocha Sousa et al, 2013). In the Sauce Grande Lake, the reduction in the basin size, water depth, and the salinity increase by the drought conditions are probably responsible for the comparatively low species richness and abundance of mesozooplankton with respect to other pampean eutrophic lakes (Chaparro et al, 2011).…”
