“…Even in the extensive fieldworks focusing the ichthyofauna of Brazilian subterranean drainages, the record of Callichthyidae is quite uncommon (see Bichuette and Trajano 2003, Mattox et al 2008, Trajano et al 2009a, 2009b, Cordeiro et al 2013, Secutti and Bichuette 2013. Recently, the first troglobitic Callichthyidae was described from a cave system in Central Brazil, Aspidoras mephisto Tencatt and Bichuette, 2017, and the fact that this species is the only species of Callichthydae occurring in a cave system of about 6 km indicates that perhaps members of this family has some ecological and/ or behavioral assumptions and maybe they cannot syntopically occur or are excluded in a competition for space and/or other resources in the subterranean drainages.…”

“…Dentre os estudos de ecologia populacional, trabalhos foram desenvolvidos com foco nas densidades e tamanhos populacionais utilizando métodos de censos visuais (Mendes, 1995;Trajano & Bockmann, 2000), e técnicas de marcação e recaptura (Trajano, 1991(Trajano, , 1997(Trajano, , 2001bTrajano et al, 2002Trajano et al, , 2009aBichuette, 2003;Trajano & Bichuette, 2007). Os estudos realizados com técnicas de marção e recaptura produzem dados mais robustos e confiáveis sobre o tamanho da população, enquanto que aqueles utilizando censos visuais, produzem dados de densidade populacional calculada com base na área ocupada pela população.…”

“…A maioria deles mostra que realmente as populações são muito pequenas, como é o caso de Amblyopsis rosae, que apresenta uma estimativa de 150 indivíduos/caverna (Willis & Brown, 1985), mas pode haver exceções, como é o caso da espécie Rhamdia enfurnada, da região da Serra do Ramalho, Bahia, que teve sua população estimada em 10.000 indivíduos (Trajano et al, 2009) e o do lambari troglóbio mexicano, com uma população estimada em 8.500 ± 7.000 indivíduos (Michell et al,1977).…”
