An immunohistochemical mapping study in the brain and upper spinal cord of the turtle Testudo hermanni Gmelin revealed a wide distribution of somatostatin perikarya and fibres. Within the telencephalon, somatostatin perikarya are present in the anterior olfactory nucleus, in the medial, dorsomedial and dorsal cortex, in the pallial thickening, in the(More)
We investigated the phylogeographic differentiation of the widely distributed African helmeted terrapin Pelomedusa subrufa based on 1503 base pairs of mitochondrial DNA (partial cyt b and ND4 genes with adjacent tRNAs) and 1937 bp of nuclear DNA (partial Rag1, Rag2, R35 genes). Congruent among different analyses, nine strongly divergent mitochondrial clades(More)
Chelodina oblonga is a long-necked, freshwater turtle found predominantly in the wetlands on the Swan Coastal Plain of Western Australia. Turtles from three populations were recorded in artificial environments set up to simulate small wetlands. Recordings were undertaken from dawn to midnight. A vocal repertoire of 17 categories was described for these(More)
AIMS The present study addressed the ability of levofloxacin to penetrate into subcutaneous adipose tissues in patients with soft tissue infection. METHODS Tissue concentrations of levofloxacin in inflamed and healthy subcutaneous adipose tissue were measured in six patients by microdialysis after administration of a single intravenous dose of 500 mg.(More)
Assisted colonization-the deliberate translocation of species from unsuitable to suitable regions-is a controversial management tool that aims to prevent the extinction of populations that are unable to migrate in response to climate change or to survive in situ. The identification of suitable translocation sites is therefore a pressing issue. Correlative(More)
Comparisons between aquatic and terrestrial species provide an opportunity to examine how sex-specific adaptations interact with the environment to influence body shape. In terrestrial female tortoises, selection for fecundity favors the development of a large internal abdominal cavity to accommodate the clutch; in conspecific males, sexual selection favors(More)
Optic nerve regeneration within the reptiles is variable. In a snake, Viper aspis, and the lizard Gallotia galloti, regeneration is slow, although some retinal ganglion cell (RGC) axons eventually reach the visual centers (Rio et al. [1989] Brain Res 479:151-156; Lang et al. [1998] Glia 23:61-74). By contrast, in a lizard, Ctenophorus ornatus, numerous RGC(More)
Plasma levels of sex steroids in both males and females of the endangered Hermann's tortoise (Testudo hermanni hermanni) were measured throughout their active period in a wild population in the Massif des Maures, France, and in a nearby captive population at Le Village des Tortues in Gonfaron. Both plasma progesterone and testosterone were elevated in males(More)
