| infectious diseases of dogs and cats on isabela island, galapagos. | vaccination and importation of dogs and cats are prohibited in the galapagos, resulting in a uniquely isolated population. the purpose of this study was to determine the prevalence of infectious diseases of dogs and cats that impact their health, could spill over to native wildlife, or sentinel diseases of concern to humans. | 2008 | 18289290 |

| behavioral and physiological adjustments to new predators in an endemic island species, the galápagos marine iguana. | for the past 5 to 15 million years, marine iguanas (amblyrhynchus cristatus), endemic to the galápagos archipelago, experienced relaxed predation pressure and consequently show negligible anti-predator behavior. however, over the past few decades introduced feral cats and dogs started to prey on iguanas on some of the islands. we investigated experimentally whether behavioral and endocrine anti-predator responses changed in response to predator introduction. we hypothesized that flight initiatio ... | 2007 | 17904141 |
| function of muscle-type lactate dehydrogenase and citrate synthase of the galápagos marine iguana, amblyrhynchus cristatus, in relation to temperature. | the galápagos marine iguana, amblyrhynchus cristatus, is unique among lizards in foraging subtidally, leading to activity across a broad range of ambient temperatures ( approximately 14-40 degrees c). to determine whether the marine iguana shows any biochemical changes consistent with maintaining enzyme function at both warm and cold body temperatures, we examined the function of the aerobic enzyme citrate synthase (cs) and the muscle isoform of the anaerobic enzyme lactate dehydrogenase (a(4)-l ... | 2008 | 18313960 |
| exposure to toxoplasma gondii in galapagos penguins (spheniscus mendiculus) and flightless cormorants (phalacrocorax harrisi) in the galapagos islands, ecuador. | toxoplasma gondii is one of the most common protozoan parasites of humans and warm-blooded animals. members of the family felidae are the only definitive hosts of this parasite and, thus, important in the epidemiology of the disease. previous studies on pacific islands have found t. gondii infections in a number of avian species where domestic cats (felis catus) have been introduced. little is known about t. gondii in the galapagos islands, although introduced domestic cats in the archipelago ar ... | 2010 | 20688714 |
