Some properties of a pheromone allowing individual recognition, from the scats of an Australian lizard, Egernia striolata

摘要: The Australian lizard, Egernia striolata, can distinguish its own scats from those of unfamiliar conspecific individuals. This appears to be unrelated diet, because there is no difference in the response lizards fed on diets that are same or different test lizard. signal induces not a visual tactile property scat structure, respond equally crushed and intact scats. We suggest pheromone secreted onto as it produced. Water solutions did contain components allowed their others. However, dichloromethane (DCM) retained unique characteristics, responded more strongly solution an lizard Further fractionation DCM pentane methanol led loss signals needed for individual recognition, but were restored when fractions recombined. infer these between individuals basis they receive complex combination chemicals.
