“…In our previous work (Gangenova et al . 2018), we showed that forest replacement by monoculture pine plantations excluded several native forest anuran species in the southern Atlantic Forest, mainly habitat specialists (e.g. Hylids).…”

“…Lastly, competitive release due to the exclusion, or abundance decline, of many other anuran species in the converted habitat (Gangenova et al . 2018) could also contribute to enhance the rate of food intake of persistent species, positively affecting their body mass and/or condition. For example, the absence of interspecific competitors and predators has been suggested to play an important role in abundance and body size increment in the Brazilian frog Phyllodytes luteolus (Mageski et al .…”

“…We used three abundant species native to the southern Atlantic Forest, which are present in both the native forest and mature tree plantations (Gangenova et al . 2018): Elachistocleis bicolor, Physalaemus cuvieri , and Odontophrynus americanus (Fig. S2 in Supporting Information).…”

“…Instead, O. americanus was shown to maintain its abundance and ranking position, and E. bicolor was shown to increase both demographic attributes in pine plantations (Gangenova et al . 2018).…”

“…In a previous study, we showed that the replacement of native forest by monoculture tree plantations in the southern Atlantic Forest of Argentina reduced richness and altered the composition of the anuran community (Gangenova et al . 2018). In the present study, we focused on those anuran species persisting in the converted habitat (pine plantations) to test the hypothesis that habitat replacement acts as a driver of phenotypic change in persistent species.…”

Species loss by habitat replacement operating as an ecological filter is a well‐known consequence of modern human activities. In contrast, the ecological and evolutionary response of species overcoming those filters in converted habitats has not been thoroughly explored. Species that persist are subject to novel and potentially stressful conditions that may induce certain morphological changes. We evaluated changes in the functional morphology of three anuran species persisting after the conversion of areas of the Atlantic Forest into pine plantations. We specifically evaluated differences in body size and body condition indices, head width, and hind legs’ length between adult individuals from both habitats and sexes. Habitat conversion and sexual dimorphism affected the morphology of the three anurans, with varying effects upon species and traits. Regarding the effect of habitat conversion, Elachistocleis bicolor increased body condition in plantations with no changes in the other traits, Physalaemus cuvieri showed only a marginal increment in residual body mass in plantations, and Odontophrynus americanus exhibited a substantial increment in body size while maintaining its body condition in plantations. Remarkably, none of the results suggested these persistent anurans were stressed by forest conversion. This study shows that habitat conversion may induce intraspecific morphological changes in ecologically relevant traits of persistent species, and that disturbed areas do not necessarily imply stressful, low quality habitats affecting all persistent native species negatively.
