The distribution of the Galapagos land iguanas Conolophus subcristatus has been strongly affected by human activities in the last century. Previously widespread throughout the whole archipelago, today they inhabit only few islands, with populations o

The extent of evolutionary divergence of phenotypes between habitats is predominantly the result of the balance of differential natural selection and gene flow. Lava lizards (Microlophus albemarlensis) on the small island of Plaza Sur in the Galapago

Land Iguanas, Conolophus subcristatus, were extirpated from Isla Baltra, Galapagos Archipelago in the 1940s. Historical records indicate that some Baltra iguanas were translocated to nearby Isla Seymour Norte in the 1930s. Plans to repatriate iguanas

Exotic predators have decimated island populations of birds and reptiles worldwide (Iverson 1978; Snell et al. 1984; Kirkpatrick & Rauzon 1986; Steadman 1986; Cruz & Cruz 1987; Fritts 1988; Case & Bolger 1991). Because of the high degree of endemism

We describe the isolation of microsatellite loci from Galapagos lava lizards (Microlophus spp.) using an enriched genomic library. Twelve loci that are polymorphic among six populations from two species are described. Characterization of these loci i

Background: Marine iguanas (Amblyrhynchus cristatus) inhabit the coastlines of large and small islands throughout the Galápagos archipelago, providing a rich system to study the spatial and temporal factors influencing the phylogeographic distributi

Physiological responses to organismal stress can have direct impacts on individual fitness. While responses to stressors mediated by glucocorticoid hormones are well studied, the regulation of the redox system via pro-oxidant and antioxidant balance

Despite the attention given to them, the Galápagos have not yet finished offering evolutionary novelties. When Darwin visited the Galápagos, he observed both marine ( Amblyrhynchus ) and land ( Conolophus ) iguanas but did not encounter a rare pink

The Galapagos land iguanas (genus Conolophus) have faced significant anthropogenic disturbances since the 17th century, leading to severe reduction of some populations and the extinction of others. Conservation activities, including the repatriation
