The X Factor in Immunity: Sex Differences Shaped by the X Chromosome

Immunological Reviews, Volume 338, Issue 1, March 2026.
ABSTRACT There are sex differences with immune responses where females exhibit stronger immune responses compared to males. Both sex hormones and sex chromosome differences between males and females contribute to the observed sex differences with innate and adaptive immune cell composition and function.

Population Structure and Reproductive Biology of the Bait Worm Sipunculus cf. nudus in Northeastern Brazil

Marine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Sipunculans are unsegmented marine annelids distributed from intertidal to deep sediments, playing important roles in nutrient cycling and ecosystem health. The Sipunculus nudus species complex is exploited as food and bait in several regions, yet reproductive data at the population level remain scarce, especially for Atlantic populations ...

Teleosts as Models for Epigenetic Inheritance

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Teleost fish exhibit a striking divergence from mammals in how they regulate their epigenome. Unlike mammals, they do not undergo the extensive DNA methylation erasure and resetting events that occur during early embryogenesis, germline specification, and spermatogenesis.

Molecular and Endocrine Regulation of Ovarian Maturation in the Black Tiger Prawn (Penaeus monodon) and Associated Challenges in Its Aquaculture

Reviews in Aquaculture, Volume 18, Issue 2, March 2026.
ABSTRACT Over the past four decades, substantial research has investigated the regulation of ovarian maturation and spawning in the black tiger prawn (Penaeus monodon). In this species, female reproduction is strongly suppressed by gonad‐inhibiting hormone (GIH) released from the eyestalk, making eyestalk ablation (ESA) the most widely adopted spawning‐
