The population consequences of sexual conflict are relatively unexplored. In a recent paper, Le Galliard et al. now show that males of the common lizard Lacerta vivipara cause such damage to females that male-biased populations decrease in size, posing a real risk to the persistence of local lizard populations. Their study reveals surprising parallels between sexual conflict and the tragedy of ...

Six nominal taxa ('Lacerta' monticola cantabrica, 'L. ' monücola monticola, 'L. ' aranica, 'L. ' aurelioi, 'L. ' bonnali, 'L. ' cyreni) of the Iberian-Pyrenean Mountain Lizards were investigated by allozyme electrophoresis with regard to IS enzymatic loci. 'L. ' horvathi was used as an outgroup for phylogenetic analysis. On the basts of our results which are in perfect agreement with karyologic...

The iguanid lizard Tropidurus peruvianus was studied along an ocean cliff and beach in northern Peru during winter. T. peruvianus inhabit arid coastal areas of Peru providing refugia such as cliffs, rock outcrops and driftwood. Lizards first appear at burrow entrances between 0730 and 0800 hrs, but may delay activity as much as four hours if conditions are unsuitable. The number of lizards acti...
