Reproduction in the Puerto Rican Teiids Ameiva exsul and A. wetmorei

We studied patterns of reproduction for the teiid lizards Ameiva exsul Cope and Ameiva wetmorei Stejneger for 1 yr in southwestern Puerto Rico. Reproduction, indexed by follicle, egg, and sperm production, and relative testis size, ceased entirely or was greatly depressed from October through January for both species. Day length was the environmental variable most closely associated with reproductive condition. Fat bodies of females reached minimal size during the months of oviposition. The larger species, A. exsul, had a larger clutch size (x̄ = 2.0) than A. wetmorei (x̄ = 1.0), but the proportion of body mass invested per clutch was similar for both species.
