Estimating ancestral states of a communicative display: a comparative study of Cyclura rock iguanas
Article Abstract:
Ancestral measures of headbob displays in iguanas are estimated based on the signature headbob displays of seven species of wild and captive Cyclura iguanas. Results suggest an evolutionary limit on headbob displays and that the predicted ancestral states can withstand violations of evolutionary assumptions. The standard errors in these ancestral phenotypes are difficult to assess without information on the forces that drive evolution. The implications of behavioral evolution on wildlife conservation are discussed.

Diving dragons; at mealtime, prehistoric-looking marine iguanas head for the sea to graze on algae
Article Abstract:
The biology and behavior of marine iguanas in the Galapagos archipelago are described. The animals feed mainly on green and red algae, and the iguanas expel the high amounts of salt in their food through their salt-excreting glands. The mating behavior of these lizards is strongly dependent on the locations of claimed territories because females are more likely to mate with males having claimed safe resting places.

Biparental care and obligate monogomy in the rock-haunting possum, Petropseudes dahli, from tropical Australia
Article Abstract:
Research into the social organization of the rock-haunting possum, Petropseudes dahli, in Kakadu National Park, Northern Australia, is presented. It is suggested that the mating system of these possums is obligate social monogamy.
