How do water skinks avoid shelters already occupied by other lizards?
Animals rely on a wide range of sensory modalities to obtain information about their environment, and to determine the most appropriate behavioural response for a give situation. Scincid lizards use both chemosensory and visual cues in tasks such as mate location, shelter-site selection, and predator evasion. Published literature has focused primarily on the use of chemosensory information by t...
متن کاملHaematological adjustments with diurnal changes in body temperature in a lizard and a mouse.
l. Hypothermic lizards (Egernia ctmninghami) showed significant reductions in plasma volume, haematocrit and haemoglobin concentration. The changes in the distribution of red cells were acutely reversible when body temperature was increased. 2. Consequently, there were no significant alterations in blood viscosity (when measured in z&o in a capillary viscometer) between body temperatures of 32°...
متن کاملMolecular phylogeography and systematics of the arid-zone members of the Egernia whitii (Lacertilia: Scincidae) species group.
We assembled a molecular phylogeny for the arid-zone members of the Egernia whitii species group to test Pianka's [Zoogeography and speciation of Australian desert lizards: an ecological perspective, Copeia (1972) 127-145] hypothesis that habitat specificity to the three major arid-zone vegetation communities is the primary cause of lizard speciation within the arid interior of Australia. This ...
متن کاملAdrenal and white cell count responses to chronic stress in gestating and postpartum females of the viviparous skink Egernia whitii (Scincidae).
This study investigates the relationships between plasma corticosterone concentrations and white cell counts in captive females of the viviparous lizard Egernia whitii during two phases of the reproductive cycle. Gestating and postpartum females were captured in the field and held in the laboratory for 4 weeks. Plasma corticosterone and progesterone concentrations and white blood cell counts we...
متن کاملFemale aggression predicts mode of paternity acquisition in a social lizard.
Individual differences in behaviour are ubiquitous in nature. Despite the likely role of selection in maintaining these differences, there are few demonstrations of their fitness consequences in wild populations and, consequently, the mechanisms that link behavioural variation to variation in fitness are poorly understood. Specifically, the consequences of consistent individual differences in b...
