Research on cephalopod early ontogeny has significantly advanced in recent decades, including embryo organogenesis and neurogenesis and early behavioural adaptations, particularly in commercially important and coastal species. Within this context, here we compiled current knowledge on the collection, handling and care under experimental conditions and monitoring in the field of cephalopod eggs and egg masses. It covers field o...

Calsequestrin 2 (CASQ2) has emerged as a central sensor and modulator of calcium (Ca 2+ ) dynamics in sarcoplasmic reticulum (SR), influencing both health and disease. This review explores the molecular architecture and multifunctional roles of CASQ2, beginning with its domain organization and Ca 2+ -binding properties and detecting how its folding and supramolecular assembly modulate Ca 2+ storage and release within cardiac m...

The ecological implications of macroplastic accumulation in rivers, particularly their role as artificial substrates for aquatic organisms, remain poorly understood, especially in the Afrotropical streams. We investigated how macroinvertebrates colonise macroplastic substrates relative to natural substrates in four minimally disturbed headwater stream sites in the Eastern Cape, South Africa. Experimental substrate groups, incl...
