Our aim was to investigate genetic structure in Neotropical populations of common green iguanas (Iguana iguana) and to compare that structure with past geological events and present barriers. Additionally, we compared levels of divergence between lineages within Iguana with those within closely related genera in the subfamily Iguaninae. 

First evidence for crossbreeding between invasive Iguana iguana and the native rock iguana (Genus Cyclura) on Little Cayman Island

In August 2016, three hybrid hatchlings were captured on Little Cayman Island, providing the first evidence for a successful crossbreeding event between I. iguana and any Cyclura rock iguana species in the wild.

Origin of the green iguana (Iguana iguana) invasion in the greater Caribbean Region and Fiji

Invasive populations of green iguanas (Iguanidae: Iguana iguana) are widely established beyond their native Central, South American, and Lesser Antillean range in various islands of the Pacific,

Population estimate, natural history and conservation of the melanistic Iguana Iguana population on Saba, Caribbean Netherlands

Intraspecific diversity is among the most important biological variables, although still poorly understood for most species. Iguana iguana is a Neotropical lizard known from Central and South

A Distribution Model for the Green Iguana, Iguana iguana (Linnaeus, 1758) (Reptilia: Iguanidae), in Puerto Rico

Habitat modeling and mapping efforts for Green Iguanas in Puerto Rico should be repeated periodically as new distributional records are obtained and the land-cover changes to provide land managers an updated distribution of this species in the islands.

The complete mitochondrial genome of the critically endangered Lesser Antillean iguana (Iguana delicatissima; Squamata: Iguanidae)

The phylogenetic utility of the mitogenome is shown with a maximum-likelihood analysis, which yields a topology concordant with previous studies of iguanine taxa.

Genetic Evidence of Hybridization between the Endangered Native Species Iguana delicatissima and the Invasive Iguana iguana (Reptilia, Iguanidae) in the Lesser Antilles: Management Implications

Investigating the hybridization dynamics between the endemic and threatened Lesser Antillean iguana and the invasive common green iguana in the LesserAntilles as well as assessing the impact of interspecific hybridization on the decline of I. delicatissima and practical conservation recommendations are being discussed in the light of these findings.

The Lesser Antillean Iguana (Iguana delicatissima) on St. Eustatius: Genetically Depauperate and Threatened by Ongoing Hybridization

There is a continued region-wide threat to I. delicatissima and the need for immediate conservation action to stop the continuing spread of Green Iguanas and to eliminate hybridization from St. Eustatius.

Testing for hybridisation of the Critically Endangered Iguana delicatissima on Anguilla to inform conservation efforts

The degree of hybridisation between Anguilla’s Iguana species is assessed firstly using morphological characteristics and then genetic analysis to validate the genetic integrity of morphologically identified I. delicatissima population, and that of a population on the nearby island of Îlet Fourchue, St Barthélemy.

A checklist of the iguanas of the world (Iguanidae; Iguaninae)

—This annotated checklist of the world's iguanas (Iguanidae; Iguaninae) represents an update by the Iguana Taxonomy Working Group (ITWG) of its 2011 list. We recognize 44 extant species (19

Describing Archaeological Iguana Laurenti, 1768 (Squamata: Iguanidae) Populations: Size and Skeletal Maturity

The goal of this study was to provide tools to estimate size and maturity of the archaeological Iguana specimens on the basis of their skeletal remains. To achieve this, a reference of 40 Iguana



Cranial Autapomorphies in Two Species of Iguana (Iguanidae: Squamata)

Iguana is a large-bodied clade of extant iguanid including the species Iguana delicatissima and Iguana iguana, which is diagnosed based primarily on a single external morphological character: presence or absence of the subtympanic plate.

Genetic Structure and Variability in the Green Iguana (Iguana iguana)

To investigate whether the disjunct distribution of nesting sites in this area and strong nesting site fidelity by female iguanas has contributed to genetic structuring of the population, samples obtained from females captured at three main nesting sites were analyzed electrophoretically.

Two genera, Pionopsitta parrots and Selenidera toucans, corroborate a well known biogeographic disjunction in which taxa endemic to southern Central America and the Chocó region of northwestern South America are the sister‐group to a radiation within the Amazon basin.

Phylogeography of the giant harlequin beetle (Acrocinus longimanus)

This study examined whether levels of DNA divergence between geographical populations provided evidence of genetically distinct lineages in the harlequin beetle to determine the existence of barriers to gene flow.

Phylogeography of the Caribbean rock iguana (Cyclura): implications for conservation and insights on the biogeographic history of the West Indies.

A molecular clock is calculated that suggests that Cyclura colonized the Caribbean between 15 and 35 mya and is recovered as monophyletic and is not closely related to any other genus, whereas Iguana is strongly supported as the sister taxon to Sauromalus.

Predation and the Defensive Behavior of Green Iguanas (Reptilia, Lacertilia, Iguanidae)

Green iguanas (Iguana iguana) are eaten by crocodiles, basilisk lizards, snakes, birds, and mammals, so cryptic coloration and behavior enhanced by group responses are especially important.

Cryptic species diversity and evolution in the amphipod genus Hyalella within central glaciated North America: a molecular phylogenetic approach

Evidence suggests that diversification has arisen as a consequence of both isolation in different glacial refugia and hab - itat specialization in populations of the amphipod crustacean Hyalella azteca, which appears to have originated as early as the mid-Miocene.

Cryptic speciation in a Holarctic passerine revealed by genetic and bioacoustic analyses

It is indicated that the two forms are reproductively isolated to a high degree where they co‐occur and are therefore separate species, and it is suggested that sexual selection played a larger role than habitat divergence in generating reproductive isolation.


DNA-sequence data suggest that S. hispidus is paraphyletic and that a minimum of 3 species exist within the currently recognized taxon, and the taxonomy should be revised to recognize the following samples as distinct species.

Origin of West Indian populations of the geographically widespread boa Corallus enydris inferred from mitochondrial DNA sequences.

Mitochondrial DNA sequences of samples from seven geographically disparate localities provided evidence of phylogenetic relationships of C. enydris and imply a fairly recent Guianan-Amazonian origin of West Indian populations.
