Glial scar formation is a major obstacle to regeneration after spinal cord injury. Moreover, it has been shown that the astrocytic response to injury differs between species. Gekko japonicas is a type of reptile and it shows differential glial activation compared to that of rats. The purpose of the present study was to compare the proliferation and migration of astrocytes in the spinal cords of...

House Geckos in the genus Hemidactylus are highly successful colonizers of regions beyond their native range, often resulting in displacement of native gecko species through competitive interactions for daytime refuge (crevices) and prey resources. We report on data collected from night time surveys undertaken in April-May 2014 on Barbados, West Indies, that focused on the distribution and abun...

Much is known about the abilities of various taxa concerning discrimination of species, sex, familiarity-based discrimination and individual discrimination. However, literature pertaining to the precision of discrimination within lizard taxa assumes that discrimination between familiar and unfamiliar individuals can be extrapolated to include individual discrimination between two familiar indiv...

A combination of X-ray tomography at different wavelengths and X-ray fluorescence analysis was applied in the study of two types of bone tissue changes: prolonged presence in microgravity conditions and age-related bone growth. The proximal tail vertebrae of geckos were selected for investigation because they do not bear the supporting load in locomotion, which allows them to be considered as a...

Sexually reproducing organisms must process and respond to internal and external stimuli to successfully synchronize physiological and behavioural processes involved in reproduction. One such cue is an individual’s social environment. Interactions with conspecifics affect a female’s reproductive activity by inducing, suppressing, and/or accelerating reproductive processes. For example, many stu...

Social interactions have lasting effects on behaviour and physiology in a variety of organisms. In the leopard gecko, Eublepharis macularius, social experience alters neural metabolism and elevates circulating concentrations of androgens. In this study, we assessed the effects of social experience (housing with females versus housing in isolation) on the expression of social behaviours in male ...

ROBERTS, JOHN S., AND BODIL SCHMIDT-NIELSEN. Renal ultrastructure and excretion of salt and water by three terrestrial lizards. Am. J. Physiol. 2 I I (1) : 476-486. I g66.-Determinations of sodium, chloride, inulin, and osmolal concentrations were made on blood and urine collected from dehydrated, waterloaded, and salt-loaded geckos, horned toads, and Galapagos lizards. Electron micrographs wer...
