Mother-offspring recognition in two Australian lizards, Tiliqua rugosa and Egernia stokesii

Article Abstract:

Australian lizards of Tiliqua rugosa and Egernia stokesii species show kin recognition even when separated from mothers at birth and kept either in isolation or with a foster mother. Both mothers and offspring have the ability to discriminate between kin and non-kin. This is evident by more attention and tongue flicks directed toward related than non-related lizards. Foster mothers spend more time with their own non-familiar young compared to familiar foster young. This mother-offspring recognition may be possible due to olfactory cues, recognition alleys, or phenotype matching.

Spatial and reversal learning in congeneric lizards with different foraging strategies

Article Abstract:

The link between foraging strategies and performance on spatial and nonspatial tasks has been investigated in congeneric lizard species Acanthodactylus boskianus, and A. scutellatus. Their performance of a spatial memory task did not differ, although A. boskianus performed better on a nonspatial task. The results raise questions about the generality of the spatial adaptation model for vertebrates.

Wall lizards combine and visual cues of ambush snake predators to avoid overestimating risk inside refuges

Article Abstract:

A study is undertaken to examine the use of different predatory cues by lizards when detecting the presence of snakes within refuges. The findings indicate that the antipredatory response of lizards is greater when they are exposed to both visual and chemical cues than when only one cue is presented.
