Is Telomere Length Optimized in Hatchling Sand Lizards?

Evolution &Development, Volume 27, Issue 4, December 2025.
The graphical abstract image depicts the complex interplay of factors driving telomere dynamics (with permission from Dr. Chris Friesen). ABSTRACT Telomeres (repeat‐DNA‐protein structures primarily located at the ends of chromosomes) protect coding DNA against attacks by reactive molecules and the cells’ own DNA repair systems.

Interaction Between Age and Individual Heterogeneity Shapes Breeding Probability in a Long‐Lived Marine Ectotherm

Ecology and Evolution, Volume 15, Issue 11, November 2025.
Using a 52‐year dataset on captive green turtles, our study reveals that individual quality and age are the primary drivers of reproductive patterns. We found that high‐quality turtles bred more consistently throughout their lives and that females maintained a high reproductive value into old age despite evidence of physical aging.

Pay up or die: Tradeoffs between costly telomere maintenance, somatic growth and body condition in embryonic and adult sand lizards

Functional Ecology, Volume 39, Issue 11, Page 3284-3298, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Current knowledge about telomere biology relies to a very high degree on results from research on endotherms. This would not be problematic if organisms shared the same mechanisms regulating telomere length (TL) but this is not necessarily the case; for example, most ...

Habitat Use and Foraging Ecology of Three Sea Turtle Species Nesting in Northwest Costa Rica

Marine Ecology, Volume 46, Issue 6, November/December 2025.
ABSTRACT Sea turtle species, even when sharing nesting beaches, exhibit distinct at‐sea movements and foraging behavior. At Playa Cabuyal, a sea turtle nesting beach in northwest Costa Rica, we utilized satellite telemetry to reveal the post‐nesting movement of green turtles (Chelonia mydas, n = 9) alongside carbon and nitrogen stable isotope analysis ...

Effects of Handling on Hatchability of Eggs of the Leatherback Turtle, Dermochelys coriacea (L.) [PDF]

, 1985
The infertility rate among clutches of leatherback sea turtle (Dermochelys coriacea) eggs incubated in the hatchery at Rantau A bang, Malaysia is estimated at 22%. Variance in hatchability among fertile clutches ranges from 35.7- 96.
