“…Studies on the habitats and populations of wild fauna were produced later, using the landscape structure analysis (Fahrig and Merrian, 1985;Fahrig and Paloheimo, 1988;Dunning et al, 1992;Johnson et al, 1992;Anderson and Gutzwiller, 1994;Danielson and Anderson, 1999;With, 1999). The influences of the territory space-structure were investigated on single species and their home-range (Temple, 1986;Haila et al, 1987;Robbins et al, 1989;McGarigal and McComb 1995;Clark, 1999;Glennon and Porter, 1999;Kie et al, 2001;Fearer and Stauffer, 2004;Said and Servanty, 2005;Jimenez-Garcia et al, 2006;Belda et al, 2007;Martinez-Perez et al, 2007). Different authors produced a series of indices (landscape ecology metrics, LEM) to estimate the space structure of the territory (Shannon and Weaver, 1949;Simpson, 1949;O'Neill et al, 1988;Gustafson and Parker, 1992;Li and Reynolds, 1995;Ritters et al, 1995;Gustafson, 1998;Hargis et al, 1998;Jaeger 2000).…”
