rekordy: Mary River turtle

Evidence: 100 • authority: 72

The Mary River turtle (Elusor macrurus) is an endangered species of short-necked turtle in the family Chelidae. The species is endemic to the Mary River in south-east Queensland, Australia. Although this turtle was known to inhabit the Mary River for nearly 30 years, it was not until 1994 that it was recognised as a new species. There has been a dramatic decrease in its population due to low reproduction rates and an increase of depredation on nests.

The green sea turtle (Chelonia mydas), also known as the green turtle, black sea turtle, and Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of C. mydas is covered by a large, teardrop-shaped carapace; it has a pair of large…

Complete mitochondrial genome of the endangered Mary River turtle (Elusor macrurus) and low mtDNA variation across the species’ range. Elusor macrurus is an endangered short-necked turtle restricted to the Mary River catchment in south-eastern Queensland. Shotgun sequencing of genomic DNA was used to generate a complete mitochondrial genome sequence for E. macrurus using the Illumina MiSeq platform. The mitogenome is 16 499 base pairs (bp) long with 37 genes arranged in the typical vertebrate order and a relatively short 918-bp control region, which does not feature extensive tandem repeats as observed in some turtles. Primers were designed to amplify a 1270-bp region that includes 81% of t…

Nonlethal age estimation of three threatened fish species using DNA methylation: Australian lungfish, Murray cod and Mary River cod.. Age-based demography is fundamental to management of wild fish populations. Age estimates for individuals can determine rates of change in key life-history parameters such as length, maturity, mortality and fecundity. These age-based characteristics are critical for population viability analysis in endangered species and for developing sustainable harvest strategies. For teleost fish, age has traditionally been determined by counting increments formed in calcified structures such as otoliths. However, the collection of otoliths is lethal and therefore undesir…

Lower cretaceous avian-dominated, theropod, thyreophoran, pterosaur and turtle track assemblages from the Tugulu Group, Xinjiang, China: ichnotaxonomy and palaeoecology.. Rich tetrapod ichnofaunas, known for more than a decade, from the Huangyangquan Reservoir (Wuerhe District, Karamay City, Xinjiang) have been an abundant source of some of the largest Lower Cretaceous track collections from China. They originate from inland lacustrine clastic exposures of the 581-877 m thick Tugulu Group, variously divided into four formations and subgroups in the northwestern margin of the Junggar Basin. The large Huangyangquan track assemblages occur in the Lower layer/Subgroup II. Similarly-composed tra…

Siebenrockiella crassicollis (commonly known as black marsh turtle, smiling terrapin, and Siamese temple turtle, among others) is a freshwater turtle endemic to Southeast Asia. It is one of two species classified under the genus Siebenrockiella in the family Geoemydidae. Black marsh turtles are small to medium-sized turtles that are almost completely black except for white to yellow markings on the head. They are largely aquatic and prefer slow-moving or still bodies of water with heavy vegetation. Black marsh turtles are also commonly kept as pets and as sacred animals in Southeast Asian Buddhist temples. They are classified as endangered by the IUCN, being one of the several Southeast Asi…

The painted turtle (Chrysemys picta) is North America's most widespread native turtle, with a rich evolutionary history that stretches back 15 million years. As resilient survivors belonging to the pond turtle family Emydidae, these turtles adapted creatively to the planet's changing climate. During the last Ice Age, they split into distinct groups and evolved into three regionally unique subspecies: the Eastern painted turtle (found along the Atlantic coast), the Midland painted turtle (living around the Great Lakes), and the Western painted turtle (the largest group, spanning the west coast and Canada). Scientists still debate whether a fourth group, the Southern painted turtle, is its ow…
