The frog ‘pants’ are made up of tiny hand-made silicon waist bands and a tracking device.
They wanted to find out how these male and female frogs navigate. The study was based on sex differences in spatial behavior across three poison frog species with contrasting parental sex roles and reproductive strategies.
. "It's a lot of fine motor skills and a lot of practice in handling tiny frogs and sewing little frog harnesses. But we go find them in the rainforest, and we catch them, and we put the tags on." “The frogs sit in the bath for a half hour before and after translocation,” explained Stanford biologist Lauren O’Connell. The frogs release hormones into the water and then, “we extract hormones from the bath water back at the lab.”The results of the tracking showed that male poison frogs are generally more explorative and have androgen levels which is consistent with the androgen-spillover hypothesis.
