Inter-population variation of carotenoids in Galápagos land iguanas (Conolophus subcristatus)

Comparative Biochemistry and Physiology - B Biochemistry and Molecular Biology, 2005
Carotenoids have received much attention from biologists because of their ecological and evolutionary implications in vertebrate biology. We sampled Galápagos land iguanas (Conolophus subcristatus) to investigate the types and levels of blood carotenoids and the possible factors affecting inter-population variation.

Plasma concentrations of progesterone and estradiol and the relation to reproduction in Galápagos land iguanas, Conolophus marthae and C. subcristatus (Squamata, Iguanidae)

Animal Reproduction Science, 2016
In a combined approach, endocrine and ultrasonic analyses were performed to assess reproduction of two syntopic populations of terrestrial Galápagos iguanas the Conolophus marthae (the Galápagos Pink Land Iguana) and C. subcristatus on the Volcán Wolf (Isabela Island).

Temporal and Spatial Covariation of Gender and Oxidative Stress in the Galápagos Land IguanaConolophus subcristatus

Physiological and Biochemical Zoology, 2009
Abstract 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 as well as the natural causes of oxidative stress in nature remain poorly known, especially for

Hybridization between the Galápagos land and marine iguana (Canolophus subcristatusandAmblyrhynchus cristatus) on Plaza Sur

Journal of Zoology, 1997
Hybridization plays an important role in the evolution of some of the vertebrate taxa on the Galápagos Islands, such as the Darwin finches. Conversely, only a single possible hybrid between the Galápagos marine iguana (Amblyrhynchus) and the land iguana (Conolophus) has been reported from the island Plaza Sur.

Reproduction in the Iguana Conolophus subcristatus on Fernandina Island, Galapagos: Clutch Size and Migration Costs

American Naturalist, 1983
Adult land iguanas (Conolophus subcristatus) on Fernandina Island, Galapagos, live in an unpredictable, predator-free environment. They lack resource competitors. The population structure allows direct comparison of adaptations to varying environments because the entire population can be assumed to share the same genetic background. Reproductive effort
