AI Article Synopsis

  • The Chinese skink has multiple subspecies and is found in various regions including China, Taiwan, and Korea.
  • Recent research has used both physical and genetic analysis to clarify the taxonomic status of specific subspecies found in Taiwan and nearby islets.
  • Eastern Taiwanese populations show unique juvenile color patterns and genetic differences that warrant their classification as a distinct species, while western Taiwanese populations are genetically similar to mainland subspecies.

Article Abstract

The Chinese skink, (Gray, 1838), is widely distributed across continental China, Taiwan, the Korean Peninsula, and offshore islets, and consists of several subspecies. Here morphological and molecular methods have been used to reassess the taxonomic status and distributions of (Van Denburgh, 1912) and (Hikida, 1988), which are endemic to Taiwan and Green Island (an islet off the east coast of Taiwan), respectively. It can be confirmed that the eastern Taiwanese populations of exhibit similar juvenile color patterning and genetic composition to the islet subspecies , and are distinct from consubspecific populations in western Taiwan. Therefore, the eastern Taiwanese populations are assigned to , and this subspecies is recognized as a distinct species, (Hikida, 1988), based on their unique juvenile coloration and highly divergent DNA sequences. Our results also revealed that in western Taiwan is close to nominotypical subspecies from the continent, suggesting the necessity of a comprehensive taxonomic analysis in the future.

Ontogenetic color change in animals is an interesting evolution-related phenomenon that has been studied by evolutionary biologists for decades. However, obtaining quantitative and continuous color measurements throughout the life cycle of animals is a challenge. To understand the rhythm of change in tail color and sexual dichromatism, we used a spectrometer to measure the tail color of blue-tailed skink () from birth to sexual maturity.

Based on its phylogenetic relationship to monitor lizards (Varanidae), Gila monsters (Heloderma spp.), and the earless monitor Lanthanotus borneesis, the Chinese crocodile lizard, Shinisaurus crocodilurus, has been assigned to the Toxicofera clade, which comprises venomous reptiles. However, no data about composition and biological activities of its oral secretion have been reported.

The crocodile lizard () is an endangered ancient reptile species. Captive breeding is an important conservation measure for the potential restoration and recovery of their wild populations. However, a skin ulcer disease caused by an unknown pathogen has become a serious threat to captive breeding individuals.

Maternal egg care enhances hatching success and offspring quality in an oviparous skink.

Maternal egg-caring behavior can often be observed in oviparous scincid lizards. The expression of such behavior is predictably affected by the trade-off between its resultant costs and benefits for mothers and/or offspring, which has been investigated in only a few scincid species. Here, post-ovipositional Plestiodon chinensis females were treated to care for their egg clutches without interference, under simulated predation pressure, or to be care-deprived.

The complete mitochondrial DNA (mtDNA) for the Chinese short-limbed skink ( Gray, 1845) was described by using next-generation sequencing. The total length of mtDNA was 16,840 bp, which contained 13 (, , , , , and ), 22 transfer RNA () genes, 2 ribosomal RNA () genes, and a control region (). The Bayesian inference tree showed that was a sister taxon to other scincid lizards in genera of , , and .
