Wetland salinity induces sex-dependent carry-over effects on the individual performance of a long-distance migrant

Abstract Salinization is having a major impact on wetlands and its biota worldwide. Specifically, many migratory animals that rely on wetlands are increasingly exposed to elevated salinity on their nonbreeding grounds. Experimental evidence suggests that physiological challenges associated with incr...
