A study demonstrated that the responses of amphipods to ultraviolet radiation depend on the sex.
The intertidal are important areas for feeding, refuge and nursery of several species. We studied the combined effect of solar radiation and diet in one of the most abundant crustaceans of the Patagonian intertidal, the amphipod Ampithoe valida.
The response of amphipods was different depending on their sex. UVR did not affect the survival of males but it did in females, even when they accumulated higher amounts of photoprotective compounds (acquired through the diet).
