Intraspecific Variation in Reproductive Aspects of Female Soldier Crabs, Mictyris guinotae, Between the River Mouth and Upper Reach Habitats

open access: yesMarine Ecology, EarlyView.
ABSTRACT The soldier crab, Mictyris guinotae, is a dominant intertidal crustacean associated with sand flats in the vicinity of the Urauchi River estuary on Iriomote Island, Japan. We compared various aspects of its reproductive biology at two sites (the river mouth and upper reach) on exposed bare sand flats 300 m and 3000 m upstream from the mouth ...

Trade‐offs in thermal response: Schizotetranychus brevisetosus winter eggs outperform summer eggs at low temperatures

open access: yesPhysiological Entomology, EarlyView.
We investigated maternal effects in Schizotetranychus brevisetosus (Tetranychidae), where females oviposit summer and winter eggs in response to photoperiod on evergreen hosts. Developmental rates of immature individuals increased linearly from 15°C to 35°C, but winter and summer eggs developed faster at low and high temperatures, respectively ...

Molecular Interplay of PARN and Telomerase: Tail Modifiers and Disease Implications

open access: yesWIREs RNA, Volume 17, Issue 4, July/August 2026.
Schematic representation of the molecular interplay between PARN, telomerase‐associated, and the involvement of p53 in regulating telomere maintenance and genome stability. The top panel shows how normal PARN levels are involved in regulating p53 levels and balanced telomerase activity through their regulatory interaction with TERC and TERRA, thus ...
