Modulated Reproductive Periodicity in Chelonia
Ecology, 1970After 15 yr tagging at the nesting ground of Chelonia mydas at Tortuguero, Costa Rica, 447 remigration returns have been recorded. These confirm previous indications that some Tortuguero females return to nest every 2 yr and some every 3 yr, with the latter being the more frequent cycle.

KARYOLOGICAL RELATIONSHIPS IN TURTLES (REPTILIA: CHELONIA)
Canadian Journal of Genetics and Cytology, 1972The mitotic chromosomes of 33 species of chelonians representing 22 genera and six families were investigated. Chromosome number and morphology are the same for most members of a given family and range from 66 in Trionyx to 34 in Pelomedusa. Most emydid genera have 50 chromosomes.

Endoscopic renal evaluation and biopsy of chelonia
Veterinary Record, 2004Sixty‐nine tortoises, turtles and terrapins representing 28 species of the order Chelonia, class Reptilia were evaluated by endoscopy for renal disease. Under general anaesthesia, coelomic and/or extracoelomic endoscopic evaluations and biopsies of the kidney(s) were undertaken.

การตรวจหาชิ้นดีเอ็นเอที่มีความจำเพาะต่อเพศในเต่าตนุ Chelonia mydas
เพื่อหาวิธีการตรวจเพศของลูกเต่าตนุโดยลูกเต่าที่ผ่านการตรวจสอบยังคงมีชีวิตอยู่จึงทำการทดลองเพื่อหาชิ้นดีเอ็นเอที่มีความจำเพาะต่อเพศของเต่าตนุโดยใช้เทคนิคทางพันธุวิศวกรรม 2 เทคนิค คือ RFLP (เซาท์เทิร์นบลอทไฮบริไดเซชัน) และ PCR–based DNA fingerprinting ใช้ GATA repeats จำนวน 21 เบส ซึ่งเป็นลำดับเบสที่จำลองมาจากส่วน conserved sequence ใน Bkm sequence ซ ...openaire +1 more source
