Uma nova espécie de anfípode cavern ícola do Brasil-Hyalel/a caeca sp.n. (Amphipoda, Hyalellidae).

Distributional patterns of the South American species of Hyalella (Amphipoda: Hyalellidae)

“…Distributional data for this study were obtained from the literature (Lopretto 1982(Lopretto , 1983aPereira, 1985, 1989Pereira et al 1985, 1989Stock and Plavoet 1991;Bond-Buckup and Araujo 1998;Casset et al 2001;González and Coleman 2002;González andWattling 2002a-c, 2003a-d;Carrera and Günkel 2003;González 2003;Jergentz et al 2004;Pereira 2004;Coleman & González, 2006;Galan & Herrera, 2006;González et al 2006;Da Silva and BondBuckup 2008;Dos Santos et al 2008;Dutra et al 2008;Zilli et al 2008;Rauque and Semenas 2009;Spaccesi & Rodríguez. 2009;De los Ríos et al 2007, 2010De los Ríos and Roa 2010;Cardoso et al, 2011;Bastos-Pereira & De Padua-Bueno, 2012 (Brehm-Lunz, 1928, 1935Gonzalez & Wattling, 2003c;González et al, 2006) Coordinates of localities were obtained from the literature or calculated on maps and rounded to minutes.…”

“…H. caeca Pereira & Goulart 1989. BRAZIL: Gruta Tobias de Baixo, Município de Ipiranga (around 23º 26' S; 47º 25' W) (Pereira 1989). Hyalella carstica (Bastos-Pereira & Bueno, 2012).…”

Reproductive strategies of two sympatric species of Hyalella Smith, 1874 (Amphipoda, Dogielinotidae) in laboratory conditions

“…The life cycles of the species of Hyalella that occur in Brazil are not known. The majority of studies on Hyalella in Brazil have emphasized the systematic of the group (Pereira 1989(Pereira , 2004Bond-Buckup and Araujo 1998;González et al 2006). Amphipods are frequently used as bioindicators and biomonitors in a variety of aquatic ecosystems because they are found in marine, terrestrial, and freshwater environments (Borgmann et al 1989;Buyle 1989;Nelson and Brunson 1995;Duan et al 1997;Rinderhagen et al 2000).…”

“…However, some species are sympatric, such as Hyalella pleoacuta González, Bond-Buckup, andAraujo, 2006 andH. castroi González, Bond-Buckup, andAraujo, 2006; others live in caves, such as H. caeca Pereira, 1989; and one species, H. rionegrina Grosso and Peralta 1999, is found in wet soils (Grosso and Peralta 1999). The main aim of this study was to test theoretical predictions that sympatric species might show different reproductive strategies to facilitate their coexistence.…”

A new species of freshwater amphipod (Dogielinotidae, Hyalella) from Southeastern Brazil

“…In Brazil the majority of species is found in streams, lakes and rivers, while the others may be found inhabiting caves, wetlands and hypothelminorheic habitats (Pereira, 1989;Grosso and Peralta, 1999;González et al, 2006;Cardoso et al, 2011;Rodrigues et al, 2012). All records of Hyalella species from Brazil are located on Southern and Southeastern regions.…”
