Changes in Plasma Testosterone, Estrogen and Progesterone Concentrations Throughout the Annual Reproductive Cycle in Male Viviparous Blue tongued Skinks, Tiliqua nigrolutea, (Scincidae), in Tasmania
... Abstract.— Few published studies have detailed comprehensively the correlations between plasma steroid hormone peaks and the timing of reproductive events in male squamate reptiles. We examined the patterns of plasma ...

Multiennial Reproduction in Females of a Viviparous, Temperate zone Skink, Tiliqua nigrolutea
... Abstract: Reproductive frequency in captive and wild-caught female Tiliqua nigrolutea was examined over five consecutive reproductive seasons. Reproductive frequency (0.38 ± 0.035) was clearly different ...

Fecal testosterone concentrations may not be useful for monitoring reproductive status in male blue tongued lizards (Tiliqua nigrolutea: Scincidae)
... We collected fecal samples from captive male Tiliqua nigrolutea from March 1997 – February 1999. The wild-caught animals were held at the University of Tasmania in semi- natural conditions. Male and female ...

Steroids and Reproductive Biology in the Blotched Blue tongued Lizard, Tiliqua nigrolutea
... Peripheral tissues potentially capable of steroid metabolism were collected from male and female Tiliqua nigrolutea at autopsy of freshly killed individuals between April 1995 and February 1996. Male and ...

Mating behaviour in the blotched blue tongued lizard, Tiliqua nigrolutea, in captivity
... Southern or blotched blue-tongued lizards, Tiliqua nigrolutea, are large, viviparous skinks distributed throughout southeastern Australia (Cogger, 1992). Adult males can range from 25–29 cm snout–vent ...

Pregnancy limits lung function during exercise and depresses metabolic rate in the skink Tiliqua nigrolutea
... High gestational loads have been associated with a range of ecological costs, such as decreased locomotor ability; however, the physiological mechanisms that underpin these changes are poorly understood. In this study, ...

Steroids and Reproductive Biology in the Blotched Blue tongued Lizard, Tiliqua nigrolutea
... Peripheral (extragonadal) metabolism of T and E2 in a number of reproductively relevant steroid target tissues is compared at times of year chosen to represent three clearly distinctive reproductive conditions in each ...

Response to gonadotropin releasing hormone challenge: Seasonal variation in steroid production in a viviparous lizard, Tiliqua nigrolutea
... The hypothalamic–pituitary–gonadal axis plays a central role in the regulation of gamete maturation, sex steroid production and the stimulation of reproductive behaviours in vertebrates. In seasonal breeders, the timely ...

Changes in Plasma Progesterone, Estrogen, and Testosterone Concentrations throughout the Reproductive Cycle in Female Viviparous Blue Tongued Skinks, Tiliqua nigrolutea (Scincidae), in Tasmania
... sampling period (Sept A) was not included in analyses as some animals had not yet emerged from hibernation at that time. Annual patterns of mean p lasma steroid concentrations were examined in both pregnant and quiescent ...

Prey capture behaviour by pygmy bluetongue lizards with simulated grazing
... Abstract: Endemic biota of native grasslands commonly co-exist with introduced grazing mammals, and often this is seen as a conservation threat. The endangered pygmy bluetongue lizard (Tiliqua adelaidensis) is ...
