Density-dependent scent glands in desert iguanas
Article Abstract:
Male desert iguanas use femoral gland secretions to demarcate their territory and assert their occupation of an area. Male adult igaunas have more active femoral glands than their female counterparts and the secretions from these glands can withstand degredation over long periods of time. Research indicates that these may be used to mark the home range. Female iguanas have active femoral glands only when their territory does not overlaps with that of a male. Under such conditions of low population density, female femoral secretions are used to indicate their presence to their conspecifics.

Chemical recognition of unfamiliar conspecifics by green iguanas: functional significance of different signal components
Article Abstract:
A study using male green iguanas found they were able to identify between femoral gland secretions of controls, themselves, familiar males, and unfamiliar males, and responded similarly to secretions from controls, familiar males and themselves. Testing took place in the iguana's home enclosure, and their own and familiar males's odours could have been present at the time of the testing. The function of these secretions appears to be to mark territory.

Lekking in marine iguanas: female grouping and male reproductive strategies
Article Abstract:
Lekking behavior in marine iguanas allow small territorial males to increase reproductive success by associating with large males. This behavior is motivated by females' preference to mate with the largest territorial males regardless of lek size. However, the reproductive success of small territorial males increases with lek size. Male clustering behavior seems driven by females' propensity to mate in leks with high stimulation rates.
