Hyperphalangy in a new sinemydid turtle from the Early Cretaceous Jehol Biota [PDF]

PeerJ, 2018
Hyperphalangy is a rare condition in extant aquatic turtles, and mainly limited to soft-shelled turtles. Here we report a new freshwater turtle, Jeholochelys lingyuanensis gen. et sp. nov. from the Early Cretaceous Jehol Biota of western Liaoning, China.

Narrowband noise induces frequency-specific underwater temporary threshold shifts in freshwater turtles [PDF]

JASA Express Letters
Freshwater turtles exhibit temporary threshold shifts (TTS) when exposed to broadband sound, but whether frequency-restricted narrowband noise induces TTS was unknown.

Alien Freshwater Turtles in Greece: Citizen Science Reveals the Hydra-Headed Issue of the Pet Turtle Trade

Diversity, 2023
Citizen science is emerging as a powerful tool for the early detection of biological invasions. The exotic pet trade has been deemed as the most significant cause of establishment for reptiles, and among them, turtles have the highest number of ...

Not only pond sliders: freshwater turtles in the water bodies of the Milan northern urban area (Italy)

Natural History Sciences, 2021
Freshwater turtles represent one of the most common pets released in urban water bodies. In Europe, after the ban on the import of Trachemys scripta, other non-native turtle species now dominate the legal pet trade.

Experimental feeding of Hydrilla verticillata colonized by stigonematales cyanobacteria induces vacuolar myelinopathy in painted turtles (Chrysemys picta).

PLoS ONE, 2014
Vacuolar myelinopathy (VM) is a neurologic disease primarily found in birds that occurs when wildlife ingest submerged aquatic vegetation colonized by an uncharacterized toxin-producing cyanobacterium (hereafter "UCB" for "uncharacterized cyanobacterium")

Nocturnal basking in freshwater turtles: A global assessment

Global Ecology and Conservation, 2023
Diurnal basking (“sunning”) is common in many ectotherms and is generally thought to be a behavioural mechanism for thermoregulation. Recent studies have reported the occurrence of nocturnal basking in a few distantly-related species of freshwater turtles, but the true extent of this behaviour is unknown, and it may be underreported due to sampling ...

Turtles in trouble. Conservation ecology and priorities for Australian freshwater turtles

Austral Ecology, 2023
AbstractThe Australian freshwater turtle fauna is dominated by species in the family Chelidae. The extant fauna comprises a series of distinct lineages, each of considerable antiquity, relicts of a more extensive and perhaps diverse fauna that existed when wetter climes prevailed.

The head and neck anatomy of sea turtles (Cryptodira: Chelonioidea) and skull shape in Testudines. [PDF]

PLoS ONE, 2012
Sea turtles (Chelonoidea) are a charismatic group of marine reptiles that occupy a range of important ecological roles. However, the diversity and evolution of their feeding anatomy remain incompletely known.Using computed tomography and classical ...

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...
