Female-biased sex ratios despite stable genetic sex determination across a climatic gradient in a marine fish

Sandra Lorena Ament‐Velásquez, Trond Amundsen, Sebastian Wacker…·Ivain Martinossi‐Allibert

The paper investigates adult sex ratio bias in a marine fish across a climatic gradient, finding female bias arises from ecological factors rather than genetic or environmental sex determination.

Sexual display behavior follows consistent sex-specific reaction norms across latitude in response to operational sex-ratio.

Ivain Martinossi‐Allibert, Sebastian Wacker, Clàudia Aparicio-Estalella…·Trond Amundsen

The paper examines how sexual display behavior in two-spotted goby populations follows consistent sex-specific reaction norms across latitude in response to operational sex ratio.
