| contents | Histological and Macromolecular Characterization of Folliculogenesis in Loggerhead Sea Turtles (): Novel Insights into the Onset of Puberty. Di Renzo, Ludovica Trotta, Erica Notarstefano, Valentina Zonta, Laura Giorgini, Elisabetta Marisaldi, Luca Mariani, Giulia Di Francesco, Gabriella Rubini, Silva Matiddi, Marco Silvestri, Cecilia Kaska, Yakup Chemello, Giulia Gioacchini, Giorgia Animals Turtles Female Ovarian Follicle Sexual Maturation Spectroscopy, Fourier Transform Infrared Vitellogenesis The Adriatic Sea is a critical neritic habitat for juvenile and adult female loggerhead sea turtles (), where intense anthropogenic pressures and environmental stressors may influence their reproductive biology. Knowledge on the onset of puberty in this population is limited by scarce information on the sub-adult stage, a transitional phase in which reproductive competence is acquired. This study integrated histological analysis and Fourier-transform infrared (FTIR) imaging spectroscopy to provide both structural and biochemical characterization of folliculogenesis, with emphasis on vitellogenesis, in from the north-central Adriatic Sea. Histological analysis determined the progression of follicle development, while FTIR imaging, a label-free and spatially resolved technique, mapped the distribution of proteins, lipids, and nucleic acids across ovarian compartments. Logistic regression estimated the size at which 50% of females are sexually mature (L) at 58.54 cm Curved Carapace Length (CCL). Based on this value, 60% of sub-adult females were already mature, indicating earlier puberty than previously inferred from macroscopic criteria. These preliminary results, along with reports of sporadic nesting in the Adriatic, raise the question of whether this basin may host further nesting events in the future. FTIR imaging proved to be a powerful tool for reproductive biology in non-model marine vertebrates. |
