Abstract
Activity, tail loss, growth and survivorship of male Psammodromus algirus Alfredo Salvador 1 , José P. Veiga 1 Male lizards may increase activity and mobility during the breeding season to patrol their home range more effectively and increase access to fe- males (Ruby, 1981). However, male reproduc- tive effort might compromise survival (Marler and Moore, 1991; Salvador et al., 1996). More active males may suffer higher predation pres- sure. While autotomy may provide an immedi- ate benefit to survival (Arnold, 1988), associ- ated costs during tail regeneration, such as re- duced growth and survival might have a nega- tive impact on future reproductive output (Vitt et al., 1977; Schwarzkopf, 1994). Here we present the results of a field study on Psammodromus algirus lizards which investi- gates male activity during the reproductive sea- son, and their effects on tail loss; we also exam- ine the consequences of tail loss to survival and growth in the next reproductive season. Field work was carried out in a deciduous oak-forest ( Quercus pyrenaica ) near Navacer- rada, Madrid province, Spain, during the 1997 breeding season (i.e., March-May). From Feb- ruary 1-15, we established a 100 × 60 m grid with markers every
