Shark pups lose gains in stressed environments

Media Release ARC Centre of Excellence for Coral Reef Studies 17. September 2019 — — — — — — — — — — A prominent JCU shark researcher is part of an international team that found shark babies can’t reach their physical peak if they’re born into environments degraded by human-induced stressors, including climate change.

Same species, different prerequisites: investigating body condition and foraging success in young reef sharks between an atoll and an island system Ornella C. Weideli, Ian A. Bouyoucos, Yannis P. Papastamatiou, Gauthier Mescam, Jodie L. Rummer, Serge Planes ABSTRACT: Acquiring and storing energy is vital to sharks of all age-classes. Viviparous shark embryos receive endogenous maternal

High-performance suction feeding in an early elasmobranch Michael I. Coates, Kristen Tietjen, Aaron M. Olsen, John A. Finarelli ABSTRACT: High-performance suction feeding is often presented as a classic innovation of ray-finned fishes, likely contributing to their remarkable evolutionary success, whereas sharks, with seemingly less sophisticated jaws, are generally portrayed as morphologically conservative throughout their history.
