“…To test the prediction that anvils are located near trees or boulders providing visual coverage and escape routes, we measured the distance from the center of the region with pits to the nearest tree trunk (i.e., a potential escape route) with a DBH (Diameter at Breast Height) of at least 8 cm was measured (this size corresponds to an average DBH of the trees in this habitat; Rodal et al, 1998;Farias and Castro, 2004). When multiple branches or trunks were present at breast height, we measured each limb and added the values.…”

“…Neste grupo, foi observado um subgrupo (A1) onde se encontra a Lima 1977, Fonseca 1991, França et al 1997, Camacho 2001, Alcoforado-Filho et al 2003, bem como nas caatingas sobre solos arenosos Araújo et al 1998Araújo et al , 1999Lemos & Rodal 2002;Pereira et al 2002;Rocha et al 2004;Farias & Castro 2004). Queiroz (2006b) destacou que a importância da família Leguminosae nas caatingas está relacionada não só à riqueza de espécies mas também ao fato dela contribuir com o maior número de espécies endêmicas.…”

“…Por meio de inventários fitossociológicos realizados na Caatinga, com a finalidade de se estabelecer relações entre solo e planta (Santos, 1987;Silva, 1991;Rodal, 1992, Camacho, 2001), de conhecimento florístico e fitossociológico (Araújo et al, 1995;Rodal et al, 1998;Farias & Castro, 2004;Costa et al, 2007;Barbosa et al, 2007), de comparação entre levantamentos florísticos, segundo condições edafoclimáticas (Rodal, 1992, Alcoforado Filho et al, 2003Rocha et al, 2004;Trovão et al, 2004;Reis et al, 2006;Santos et al, 2007), e de inventariar as caatingas arbustivo-arbóreas, de acordo com diretrizes da SUDENE (Tavares et al, 1969a(Tavares et al, , 1969b(Tavares et al, , 1970(Tavares et al, , 1974a(Tavares et al, , 1974b(Tavares et al, , 1975 identificaram-se locais com menor diversidade de espécies arbóreo-arbustivas da caatinga, que incluem a região do Seridó e da microrregião salineira no Rio Grande do Norte, e o Vale do Cariri na Paraíba, onde na maioria dos levantamentos ocorreram menos de 10 espécies.…”
