“…All three species showed well-developed homing ability, which is consistent with previous studies in amphibians, including various anurans ( Arcila-Pérez et al, 2020 ; Dole, 1968 ; McVey et al, 1981 ; Navarro-Salcedo et al, 2021 ; Navarro-Salcedo et al, 2022 ; Pašukonis et al, 2014 ; Pašukonis et al, 2018 ; Pichler et al, 2017 ; Shaykevich et al, 2021 ; Sinsch, 1987 ; Sinsch, 1992 ) and caudates ( Diego-Rasilla et al, 2005 ; Grant et al, 1968 ; Joly and Miaud, 1989 ; Phillips et al, 1995 ; Sinsch, 2007 ; Twitty et al, 1964 ; reviewed in Ferguson, 1971 ; Sinsch, 2006 ; Wells, 2010 ). Despite limited movement capacity and sedentary lifestyle, many amphibians appear to share a general ability to navigate home after translocations from distances exceeding their routine movements ( Sinsch, 1990 ; Sinsch, 2014 ).…”

Sex differences in vertebrate spatial abilities are typically interpreted under the adaptive specialization hypothesis, which posits that male reproductive success is linked to larger home ranges and better navigational skills. The androgen spillover hypothesis counters that enhanced male spatial performance may be a byproduct of higher androgen levels. Animal groups that include species where females are expected to outperform males based on life-history traits are key for disentangling these hypotheses. We investigated the association between sex differences in reproductive strategies, spatial behavior, and androgen levels in three species of poison frogs. We tracked individuals in natural environments to show that contrasting parental sex roles shape sex differences in space use, where the sex performing parental duties shows wider-ranging movements. We then translocated frogs from their home areas to test their navigational performance and found that the caring sex outperformed the non-caring sex only in one out of three species. In addition, males across species displayed more explorative behavior than females and androgen levels correlated with explorative behavior and homing accuracy. Overall, we reveal that poison frog reproductive strategies shape movement patterns but not necessarily navigational performance. Together this work suggests that prevailing adaptive hypotheses provide an incomplete explanation of sex differences in spatial abilities.

Animal groups that include species where females are expected to outperform males based on life-history traits are key for disentangling these hypotheses. We investigated the association between sex differences in reproductive strategies, spatial behavior, and androgen levels in three species of poison frogs. We tracked individuals in natural environments to show that contrasting parental sex roles shape sex differences in space use, where the sex performing parental duties shows wider-ranging movements. We then translocated frogs from their home areas to test their navigational performance and found that the caring sex outperformed the non-caring sex only in one out of three species. In addition, males across species displayed more explorative behavior than females. Furthermore, androgen levels correlated with explorative behavior and homing accuracy. Our findings suggest that poison frog reproductive strategies shape space use patterns but not navigational performance, providing counterevidence to the prevailing view of adaptive sex differences in spatial abilities.
