| ecological species replacement of liolaemus lizards along a habitat gradient. | ecological species replacement of liolaemus platei by liolaemus lemniscatus appears to occur along a north-south oriented herb density gradient. both congeners are the only ground-dwelling lizards in the area; this suggests that l. lemniscatus is an ecological counterpart of l. platei in herbaceous habitats. relatively longer legs appear to be associated with the utilization of herb-free habitats by l. platei; the shorter legs possessed by l. lemniscatus are associated with the utilization of ha ... | 1980 | 28310624 |
