Experimental evidence of a sexually transmitted infection in a wild vertebrate, the black-legged kittiwake (Rissa tridactyla)
Sexually transmitted infections (STIs) in animals may have profound eco-evolutionary consequences, yet experimental studies of the sexual transmission of pathogens in wild populations are lacking. Here to identify sexually transmitted bacteria, we experimentally manipulated ejaculate transfer in bla...
