“…Dorsal marks of individual frogs were recorded using digital cameras (Figure S1). Then, we performed a computer‐assisted matching method, using the Wild‐ID program (Java 1.5; Bolger et al, 2012; see Caorsi et al, 2012, Díaz‐Ricaurte et al, 2019). This software detects recaptures based on an algorithm of Scale Invariant Feature Transform (SIFT; Lowe, 2004), which extracts and combines the distinctive features in the image, regardless of size and orientation.…”

Understanding the mechanisms that affect habitat use by vertebrates is critical for understanding how species are distributed across landscapes and how they cope with habitat change. The Brazilian Savanna (the Cerrado) has vegetation ranging from grassland to woodland savannas and harbors a rich and diverse amphibian fauna impacted by accelerated habitat loss. Here, we test the influence of vegetation type (from grassy scrubland to woodland) and distance from breeding sites (ephemeral water bodies) on body size, abundance, and survival of the frog Physalaemus nattereri in a natural metapopulation system of south‐central Brazil. We also test whether body size is a significant predictor of population abundance. We found that the abundance of P. nattereri varies according to the mean snout–vent length of each metapopulation (sampling unit), as well as a higher estimated mortality rate in woodlands compared with typical Cerrado. Furthermore, we found no difference in estimated mortality among sampling units located far or close to ephemeral water bodies. Thus, our results highlight variable responses of P. nattereri metapopulations to environmental factors, despite the observed high heterogeneity among sampled habitats and the importance of ephemeral water bodies for reproduction. These findings highlight that land cover and availability of breeding sites might not always interact to explain population persistence of Cerrado frogs.

“…The use of color patterns of individuals is useful for unambiguously distinguishing individuals in many anurans (Donnelly et al 1994, Ferner 2010, and have been successfully used in other studies with glass frogs (e.g. Basto-Riascos et al 2017, Ospina-L. et al 2017, Díaz-Ricaurte et al 2019.…”

Phenology and mortality of embryos in a Colombian population of Nymphargus grandisonae (Anura: Centrolenidae)

Phenology and mortality of embryos in a Colombian population of Nymphargus grandisonae (Anura: Centrolenidae). Studies of phenology and natural history of anurans provide information useful for its conservation. This is particularly important in current scenarios of emergent diseases, high rates of deforestation, and climate change. We recorded the timing of breeding of the Glass Frog Nymphargus grandisonae and its relationship to precipitation and environmental temperature for four years in a population located in the Central Andes of Colombia, South America. In addition, we recorded the causes of mortality in egg clutches of this species. We quantified infestation by fly larvae and its impact on the survival of embryos. We found that the reproductive activity of N. grandisonae (number of males calling) was seasonal and occurred in months with highest precipitation. The main cause of embryo mortality in clutches was associated with the infestation by a spittlebug fly of the genus c.f. Cladochaeta (Drosophilidae). The survival of embryos in infested clutches was significantly lower than in those clutches not infested by fly larvae. Our results provide baseline data for the monitoring of anuran population dynamics in the Andean region using the glass frog N. grandisonae as a model system.

“…However, in species with so-called “first-night care” (or short-term attendance; <1 day), performed exclusively by females—a behavior that appears to be the ancestral condition for the family—the benefits are not as clear ( Delia, Bravo-Valencia & Warkentin, 2017 ), and the amount of information about their reproductive behavior is sparse and primarily anecdotal (but see Delia, Bravo-Valencia & Warkentin, 2017 ). Studies on other species of glass frogs believed to have “first-night care”, such as members of the genus Teratohyla ( Díaz-Ricaurte, Guevara-Molina & Serrano, 2019 ), Nymphargus grandisonae ( Guevara-Molina & Vargas-Salinas, 2014 ), and Centrolene lynchi ( Dautel et al, 2011 ) did not systematically examine if environmental factors influence how long mothers remain with their clutch, a potential indicator of an adaptive parental response to changes in the environment ( Delia, Ramirez-Bautista & Summers, 2013 ; Royle, Russell & Wilson, 2014 ).…”

In species with parental care behaviors, parents may adjust the intensity and duration of their care if fluctuation in factors such as environmental variables or body condition affects offspring survival. In the face of environmental changes, many egg-laying species remain with their clutch for extended periods if this behavioral adjustment provides tangible benefits to the offspring. However, the length of time parents stay with the offspring may also differ depending on the individual’s body condition. In the glass frog family (Centrolenidae), several species exhibit long-term egg attendance in which they remain with their clutch for several days after oviposition takes place. For some of them, changes in environmental variables lead to increased parental care efforts. For the species in which parents remain with their offspring for a short period (less than 24 hours), it is less clear if this constitutes parenting behavior, and whether parents adjust their efforts as a function of environmental change or the parent’s body condition remains unexplored. We studied a population of the Emerald Glass Frog, Espadarana prosoblepon, a species that exhibits a short period of quiescence after oviposition (less than three hours). Our study aimed to determine whether females alter the length of their post-oviposition quiescence period in response to changes in environmental variables (i.e., temperature, humidity, rainfall, and mean wind speed) or female body condition. Pairs in amplexus were captured in the field and transported to semi-natural enclosures to record the duration of post-oviposition quiescence using infrared cameras. Females’ post-oviposition quiescence lasted an average of 67.4 ± 26.6 min (range = 22.7–158.3 min). We did not find a significant relationship between the duration of the post-oviposition quiescence and any of the environmental variables tested. Similarly, post-oviposition quiescence duration was not influenced by female body condition. Because the variation observed in the duration of post-oviposition quiescence was not related to changes in extrinsic (environmental) or intrinsic (body condition) factors, we found no evidence that females of E. prosoblepon modify their post-oviposition behavior in response to any of the variables examined in this study. Future research investigating the adaptive significance of the post-oviposition quiescence observed in this species is needed to understand how this behavior is related to parental care efforts.
