Rapid Growth In Late Cretaceous Sea Turtles Reveals Life History Strategies Similar To Extant Leatherbacks, Laura E. Wilson
Rapid Growth In Late Cretaceous Sea Turtles Reveals Life History Strategies Similar To Extant Leatherbacks, Laura E. Wilson
Geosciences Faculty Publications
Modern sea turtle long bone osteohistology has been surprisingly well-studied, as it is used to understand sea turtle growth and the timing of life history events, thus informing conservation decisions. Previous histologic studies reveal two distinct bone growth patterns in extant sea turtle taxa, with Dermochelys (leatherbacks) growing faster than the cheloniids (all other living sea turtles). Dermochelys also has a unique life history compared to other sea turtles (large size, elevated metabolism, broad biogeographic distribution, etc.) that is likely linked to bone growth strategies. Despite the abundance of data on modern sea turtle bone growth, extinct sea turtle osteohistology …

ABSTRACT
The introduction of a new fish species into an aquatic ecosystem can bring about many challenges for fisheries managers. Questions might arise for the manager regarding the initial sportfish survival rate, grow rate, reproduction and recruitment, and what kind of impact will the introduction have on the already established populations found in the water body. A new population of fish is often protected using length limit regulations, allowing biologists to gain insight on whether the population will be self-sustaining or in need of periodic stockings. Age and growth information is used to understand population dynamics, estimate annual mortality and …
