Fatty acid methyl esters extracted from the cuticular surface of Artemia franciscana (Kellogs, 1906) (Crustacea: Anostraca) increase the swim speed of conspecific males
ABSTRACT Previous researches have established that the swim speed of some microcrustaceans is influenced by chemical compounds emitted by conspecifics. We examined the hypothesis that cuticular compounds present on the body surface of A. franciscana, the most widespread member of Artemia genus, play...
