This study of the morphology, histology, histochemistry, and ultrastructure of the Harderian gland in Geckos (Squamata, Gekkota) revealed previously unreported variation. The gecko Harderian gland is unlike that of other squamates in that each cell o

The Harderian gland is an orbital gland thought to be a source of corneal lubricant, supplementary to the other orbital glands. This study investigated the possible role of skink Harderian glands in corneal lubrication. It was hypothesized that if th

Few studies in non-mammalian vertebrates have examined how various effectors of the circadian system interact. To determine if the daily locomotor and behavioural thermoregulatory rhythms of Tiliqua rugosa are both controlled by the circadian system

This study examined whether the daily rhythms of locomotor activity and behavioural thermoregulation that have previously been observed in Australian sleepy lizards (Tiliqua rugosa) under field conditions are true circadian rhythms that persist in co

The daily rhythm of behavioral thermoregulation in sleepy lizards (Tiliqua rugosa) was studied in laboratory thermal gradients under a 12L∶12D photoperiod in autumn and spring. In both seasons, lizards showed distinctive daily rhythms of behavioral

In this paper we support the division of the previously monotypic genus Ascaphus into two species based on an analysis of 23 allozyme loci from 34 populations. We use maximum likelihood to estimate the Ascaphus phylogeny from the allozyme data and fi

This study determined whether a blood plasma melatonin rhythm persists in constant photothermal environments in the sleepy lizard, Tiliqua rugosa. It builds upon an earlier investigation which provided equivocal results as to whether an in vivo melat

The Harderian gland is an orbital structure ubiquitous in reptiles. Numerous functions have been ascribed to this gland, including osmoregulation, chemoreception, and immunity. The anatomical, histological, histochemical, and ultrastructural characte

The reptilian Harderian gland is a poorly understood cephalic structure. Despite the recent assertion that in snakes it may function as part of the vomeronasal system, the Harderian gland has been described in few snake species. In this study we exam

The luminal surface of the chemosensory epithelia of the main olfactory organ of terrestrial vertebrates is covered by a layer of fluid. The source of this fluid layer varies among vertebrates. Little is known regarding the relative development of th
