“…In our study, we did not find evidence of toe regeneration, but if it occurs, as described by Hoffmann et al. (), the mark–recapture assumption of mark retention will be violated, underestimating survival and other vital rates (Lebreton et al. ; Williams et al.…”

Amphibians have been declining worldwide and the comprehension of the threats that they face could be improved by using mark–recapture models to estimate vital rates of natural populations. Recently, the consequences of marking amphibians have been under discussion and the effects of toe clipping on survival are debatable, although it is still the most common technique for individually identifying amphibians. The passive integrated transponder (PIT tag) is an alternative technique, but comparisons among marking techniques in free-ranging populations are still lacking. We compared these two marking techniques using mark–recapture models to estimate apparent survival and recapture probability of a neotropical population of the blacksmith tree frog, Hypsiboas faber. We tested the effects of marking technique and number of toe pads removed while controlling for sex. Survival was similar among groups, although slightly decreased from individuals with one toe pad removed, to individuals with two and three toe pads removed, and finally to PIT-tagged individuals. No sex differences were detected. Recapture probability slightly increased with the number of toe pads removed and was the lowest for PIT-tagged individuals. Sex was an important predictor for recapture probability, with males being nearly five times more likely to be recaptured. Potential negative effects of both techniques may include reduced locomotion and high stress levels. We recommend the use of covariates in models to better understand the effects of marking techniques on frogs. Accounting for the effect of the technique on the results should be considered, because most techniques may reduce survival. Based on our results, but also on logistical and cost issues associated with PIT tagging, we suggest the use of toe clipping with anurans like the blacksmith tree frog.

“…Más aún, pocos son los trabajos que han evaluado alternativas a la remoción de falanges como téc-nica de marcaje (e.g. Hoffmann et al, 2008), siendo actualmente reconocida como una práctica aceptable para estudios de captura-recaptura de anfibios (Phillott et al, 2007). Seguimos la codificación de Hero (1989), debido al bajo número en el corte de discos dactilares que esta metodología implica, habiendo removido un máximo de dos terminaciones dactilares por mano y/o pie en los individuos capturados en este estudio.…”

“…In addition, in many studies, alternative marking techniques are commonly used in conjunction with, not instead of, toe clipping as a back-up for mark loss or to validate a marking technique. For example, a combination of visible implant elastomer (VIE) and toe clipping was used by Hoffmann et al (2008) in a study of hylid frogs. Likewise, alpha numeric tags were used together with toe clipping to individually mark European treefrogs, Hyla arborea (Meuche and Grafe, 2003).…”
