Effects of parasitic infection and reproduction on corticosterone plasma levels in Galápagos land iguanas, Conolophus marthae and C. subcristatus. [PDF]

Ecol Evol, 2017
AbstractIn vertebrates, one main feature of stress response is the release of glucocorticoids (corticosterone in reptiles), steroid hormones whose synthesis is regulated by the hypothalamic–pituitary–adrenal axis (HPA). In the Galápagos Islands, populations of land iguanas are differentially impacted by a tick‐transmitted apicomplexan hemoparasite of ...

Serotype Diversity and Antimicrobial Resistance Profile of Salmonella enterica Isolates From Freshwater Turtles Sold for Human Consumption in Wet Markets in Hong Kong. [PDF]

Front Vet Sci, 2022
Chelonians are recognized as a source of human salmonellosis through direct contact or consumption of their meat. Freshwater turtles sold for food are widely available in wet markets in Asia.

Salmonella strains isolated from Galápagos iguanas show spatial structuring of serovar and genomic diversity. [PDF]

PLoS One, 2012
It is thought that dispersal limitation primarily structures host-associated bacterial populations because host distributions inherently limit transmission opportunities. However, enteric bacteria may disperse great distances during food-borne outbreaks.

Transcriptomic detection of Candidatus Allocryptoplasma (Anaplasmataceae) in Galápagos marine iguanas (Amblyrhynchus cristatus, Iguanidae). [PDF]

Parasit Vectors
BACKGROUND: Globally, the disease ecology of reptiles remains understudied, even for threatened and iconic species such as the Galápagos marine iguana (Amblyrhynchus cristatus).

Locating Nesting Sites for Critically Endangered Galápagos Pink Land Iguanas (Conolophus marthae) [PDF]

Animals (Basel)
Invasive alien species control is recognized worldwide as a priority action to preserve global biodiversity. However, a lack of general life history knowledge for threatened species can impede the effectiveness of conservation actions.

A molecular protocol to distinguish syntopic Galapagos land iguanas (Conolophus marthae and C. subcristatus) from faecal samples [PDF]

, 2018
When species are endangered, rare, or hard-to-sample, noninvasive sampling methods may prove useful for the purposes of genetic studies or for collecting evidence of the presence of a species.

Host sex, size, and hemoparasite infection influence the effects of ectoparasitic burdens on free-ranging iguanas. [PDF]

Ecol Evol, 2019
Investigations focusing on host-ectoparasite interactions in animals have revealed asymptomatic to severe health and fitness consequences suggesting that species mobilize different interspecific response mechanisms.

Molecular data exclude current hybridization between iguanas Conolophus marthae and C. subcristatus on Wolf Volcano (Galápagos Islands) [PDF]

Conservation Genetics, 2018
Natural hybridization may influence population fitness and responsiveness to natural selection, in particular in oceanic island systems. In previous studies, interspecific hybridization was detected between the Galapagos iguana species Amblyrhynchus cristatus and Conolophus subcristatus.

Assessment and validation of miniaturized technology for the remote tracking of critically endangered Galápagos pink land iguana (Conolophus marthae) [PDF]

, 2020
Background: Gathering ecological data for species of conservation concern inhabiting remote regions can be daunting and, sometimes, logistically infeasible.

Field observations of cooling rates of galapagos land iguanas (Conolophus subcristatus)

Comparative Biochemistry and Physiology Part A: Physiology, 1978
Abstract 1. 1. Cooling constants and thermal conductances are calculated from the rates of cooling of three Conolophus subcristatus , the Galapagos land iguana. 2. 2. The observed conductances are lower than those of comparably large lizards including the Galapagos marine iguana, Amblyrhynchus cristatus .
