Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species
Andrology, EarlyView.ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

Antipredatory Strategies of Anurans: An Updated Conceptual Review
Ethology, Volume 132, Issue 9, Page 662-708, September 2026.To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

A neuro‐behavioural model of neophobia
Biological Reviews, Volume 101, Issue 4, Page 1863-1876, August 2026.ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.
