We present a review and analysis of the conservation status International Union for Conservation Nature (IUCN) threat categories all 360 currently recognized species extant recently extinct turtles tortoises (Order Testudines). Our is based on 2018 IUCN Red List 251 listed species, augmented by provisional assessments Tortoise Freshwater Turtle Specialist Group (TFTSG) 109 unlisted freshwater turtles, as well re-assessments several outdated assessments. Of tortoises, this combined indicates...
Assisted colonization—the deliberate translocation of species from unsuitable to suitable regions—is a controversial management tool that aims prevent the extinction populations are unable migrate in response climate change or survive situ. The identification sites is therefore pressing issue. Correlative distribution models, which based on occurrence data, limited use for site selection with historically restricted distributions. In contrast, mechanistic models hold considerable promise...
Chelodina oblonga is a long-necked, freshwater turtle found predominantly in the wetlands on Swan Coastal Plain of Western Australia. Turtles from three populations were recorded artificial environments set up to simulate small wetlands. Recordings undertaken dawn midnight. A vocal repertoire 17 categories was described for these animals with calls consisting both complex and percussive spectral structures. Vocalizations included clacks, clicks, squawks, hoots, short chirps, high medium long...
Abstract Using mitochondrial genomes and nine nuclear loci, we examined genetic variation in snake-necked turtles ( Chelodina sensu lato), with a focus on northern Australian taxa. The phylogeny of the genus is confounded by multiple introgression events, rendering subgenera stricto Chelydera non-monophyletic. However, analyses our dataset (6071 bp), recognition supported. morphologically most distinct taxa expansa , C. longicollis oblonga parkeri steindachneri ) are well differentiated...
The reproductive organs of logn‐term captive females and wild the western swamp tortoise, Pseudemydura umbrina , which were taken temporarily into captivity, studied over several years by ultra‐sound scanning. a critically‐endangered species, is active during winter spring when ephemeral swamps it inhabits contain water aestivates summer autumn (November to May/June) are dry. vitellogenic growth ovarian follicles commences aestivation in continues winter. timing cycle remarkably similar that...
The present study addressed the ability of levofloxacin to penetrate into subcutaneous adipose tissues in patients with soft tissue infection.Tissue concentrations inflamed and healthy were measured six by microdialysis after administration a single intravenous dose 500 mg. Levofloxacin was assayed high-performance liquid chromatography.The mean concentration vs time profile free plasma identical that tissues. ratios area under curve from 0 10 h (AUC(0,10 h)) 1.2 +/- 1.0 for 1.1 0.6 (mean...
Species with restricted ranges and long generation times are vulnerable to climate change due limited opportunity disperse or adapt. Australia’s rarest reptile, the western swamp turtle Pseudemydura umbrina , persists naturally in only one seasonal that holds water Austral winter spring. A marked reduction rainfall recent decades has shortened hydroperiod, restricting when turtles able feed, grow reproduce. To mitigate possible future loss of reproductive capacity native habitat, assisted...
Abstract The value of assisted colonisation as a response to climate change can only be realised if focal species are well suited their new habitats. For ectotherms, habitats must offer microclimates that promote crucial behaviours such thermoregulation and foraging. Western swamp turtle Pseudemydura umbrina , Critically Endangered from south‐western Australia, serves global case‐study in action. Initial trials where juvenile P. were released into wetter cooler climates found individuals...
Abstract Optic nerve regeneration within the reptiles is variable. In a snake, Viper aspis , and lizard Gallotia galloti slow, although some retinal ganglion cell (RGC) axons eventually reach visual centers (Rio et al. [ 1989 ] Brain Res 479:151–156; Lang 1998 Glia 23:61–74). By contrast, in lizard, Ctenophorus ornatus numerous RGC regenerate rapidly to centers, but unless animals are stimulated visually, regenerated projection lacks topography remain blind via experimental eye (Beazley 2003...
The evaluation of offspring sex ratios is important in any large-scale threatened species breeding programs if temperature-dependent determination a possibility. We assessed the ratio captive-bred juvenile Aldabra tortoises (Aldabrachelys gigantea or Dipsochelys dussumieri) at La Vanille Crocodile and Tortoise Park Mauritius. gonads small are thin elongate fixed to dorsal part body cavity, with ovaries appearing as transparent sheaths some visible oocytes testes small, transparent, thin,...
Based on the phylogenetic placement of a near-complete mitogenome sequence holotype Chelodina intergularis Fry, 1915 generated with hDNA approaches, we present evidence for synonymy this nominal species rugosa Ogilby, 1890. The type specimens both taxa are housed in Australian Museum, Sydney. Scrutinizing historical records, conclude that locality is most likely vicinity Somerset, at northern extremity Cape York Peninsula, Queensland, Australia. We figure and describe specimens. Our results...
A new subspecies of Chelodina mccordi is described from Timor-Leste (East Timor). The nominate m. endemic to the small island Roti southwest Timor. has a very limited distribution in area Lake Iralalaro Lautém District near eastern tip and that nation. In some morphological characters, intermediate between C. novaeguineae New Guinea, but, supporting its subspecific taxonomic status, taxon shows more similarities form than novaeguineae. on Island was nearly extirpated by commercial trade...
