The ratio of length at first maturity to maximum length across marine and freshwater fishes

Z Chen, J Bigman, W Xian, C Liang… - Journal of Fish …, 2022 - Wiley Online Library
The prevailing determinant of maturation in fishes is thought to be a redirection of energy
from growth to reproduction. Instead, the Gill Oxygen Limitation Theory predicts that …

Revisiting a central prediction of the Gill Oxygen Limitation Theory: Gill area index and growth performance

JS Bigman, NC Wegner, NK Dulvy - Fish and Fisheries, 2023 - Wiley Online Library
Abstract The Gill Oxygen Limitation Theory (GOLT) posits that a mismatch in oxygen supply

Maternal investment, ecological lifestyle, and brain evolution in sharks and rays

CG Mull, KE Yopak, NK Dulvy - The American Naturalist, 2020 - journals.uchicago.edu
Across vertebrates increased maternal investment (via increased pre-and postnatal
provisioning) is associated with larger relative brain size, yet it remains unclear how brain …

Gills, growth and activity across fishes

JS Bigman, NC Wegner, NK Dulvy - Fish and Fisheries, 2023 - Wiley Online Library
Life history theory suggests that maximum size and growth evolve to maximize fitness. In
