Does stress make males? An experiment on the role of glucocorticoids in anuran sex reversal
Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 2, Page 172-181, March 1, 2024.Abstract Environmentally sensitive sex determination may help organisms adapt to environmental change but also makes them vulnerable to anthropogenic stressors, with diverse consequences for population dynamics and evolution. The mechanisms translating environmental stimuli to sex are controversial: although several fish experiments supported the ...
