Male-biased sexual size dimorphism in sharks

Male-biased sexual size dimorphism in sharks: the narrowmouth catshark Schroederichthys bivius as case study Colonello, J.H., Cortés, F. & Belleggia, M. ABSTRACT: In shark populations, variation in sexual size dimorphism (SSD) appears to be related with the reproductive mode. Here, we aimed to investigate the reproductive biology of the narrowmouth catshark Schroederichthys bivius, an oviparous

Coastal breeding aggregations of threatened stingrays and guitarfish in the Levant

Coastal breeding aggregations of threatened stingrays and guitarfish in the Levant Shahar Chaikin, Jonathan Belmaker, Adi Barash ABSTRACT: 1. Stingrays and guitarfish are globally threatened by overexploitation, particularly so in the Mediterranean Sea. Nevertheless, very little information is known about their ecology, behaviour, and taxonomy in the Mediterranean, and especially in the Levant, where water

Non‐lethal assessment of reproductive stage for female blue sharks

Non‐lethal assessment of reproductive stage for female blue sharks

Non‐lethal assessment of reproductive stage for female blue sharks Prionace glauca using sex steroid hormones Y. Fujinami, Y. Semba ABSTRACT: We analysed plasma concentrations of progesterone (P4) and 17β‐oestradiol (E2) in juvenile, pre‐ovulatory, early, mid‐, or late‐pregnancy stages of female blue sharks Prionace glauca. Concentrations of P4 were significantly higher in pregnant than in non‐pregnant
