“…Vegetation height is an important influencing factor of calling site selection for several hylid species (Wells and Schwartz, 1982;Bastos and Haddad, 1999;Eterovick and Ferreira, 2008;Santos et al, 2016). Male perch height can improve visual communication between individuals (Abrunhosa and Wogel, 2004).…”

Calling site selection by male Boana punctata (Anura: Hylidae)

Amphibian species require specific conditions for reproduction, such as cover structures and shelters, in both aquatic and terrestrial habitats, which directly influence reproductive success. A careful selection of calling sites is an important process, driving life-history strategies and tactics in amphibians. Despite this, a significant knowledge gap on how different variables modulate amphibian microhabitat selection processes is noted. Thus, we aimed to: (1) describing the microhabitat use of adult neotropical Boana punctata males during the breeding season; and (2) quantitatively analyzing the selection process of five resource variables (i.e., vegetation cover, vegetation density, vegetation height, water depth, and distance to the water shore). We then compared the microhabitat selection of males that achieved spawning and that of males that did not achieve spawning. To quantify selection, we used a resource selection function approach, applying a case/control design where the calling site used by each male was paired to eight surrounding, unused locations. We found that males selected microhabitats with higher vegetation than surrounding areas for reproduction, which suggests territorialism, and selected microhabitats slightly (∼ 30 cm) inside the assessed ponds. Males also acted randomly with regard to the other variables, not influencing the males’ microhabitat selection. Microhabitat use of males successful in obtaining females to spawn was similar to that of males exhibiting mating failure. In addition to being of ecological interest, our study highlights that preserving tall vegetation and the ponds’ shores is important for the conservation of existing B. punctata urban populations.

“…For this purpose, we delimited 1 x 1 m quadrants with the individual observed location in the center. Within each quadrant, we obtained the maximum height and visually estimated (coverage percentage) the area occupied by herbaceous, shrub and tree vegetation and by flooded area (the height measurement of the occurrence of flooded area was recorded with a value of zero) (adapted from Huckembeck et al, 2012;Tozetti & Martins, 2008;Santos et al, 2016;Moser et al, 2019). If the quadrant lacked some vegetation types, we replaced the height measurement corresponding to the absent type with the maximum height of the vegetation type present at the central point of the same quadrant.…”

“…The preference for certain habitat characteristics is an adaptive trait where individuals tend to prefer and use habitats that provide a greater probability of survival and reproductive success (Fierro-Calderón & Martin, 2019). Seasonal events, such as the reproductive cycle, can affect the microhabitat preferences of animals (Santos et al, 2016). During the mating season, many anuran species share the same water body in an event called "reproductive congregations" (Toledo et al, 2003).…”

“…At a given calling site, males emit advertisement calls to attract females during this period (Wells & Schwartz, 1982). Calling site selection is based on many microhabitat resources, a subject that is still an open field for fieldwork studies, especially for neotropical anurans (Santos et al, 2016). In general, animals exhibit preferences for specific environmental characteristics, such as substrate composition, climatic conditions and vegetation types (Reinert, 1993;Tozetti et al, 2010).…”

Climatic conditions and microhabitat characteristics, such as the substrate and type of vegetation, influence the choice of male anurans for calling sites that optimize their reproductive success. We evaluated the structure and selection of vocalization microhabitat of 17 individuals of Phyllomedusa distincta Lutz, 1950 and 25 of Boana leptolineata (Braun & Braun, 1977), in a subtropical forest in southern Brazil. We measure the height of the perch, the distance between the perch and the edge of the body of water and the structure of the microhabitat of quadrants used by individuals. The same attributes were measured in the quadrants available (but not used) by the individuals. We classified the microhabitats by visual estimate, assigning percentages of coverage for each quadrant by herbaceous, shrub, tree and wetland vegetation. We observed that both species selected their microhabitat, since the characteristics of the quadrants occupied by the individuals were different from those available. Phyllomedusa distincta was more associated with heterogeneous microhabitats, while B. leptolineata occurred in environments with greater coverage of tree strata. Additionally, we observed that both species used shrubs more frequently as a perch site. The selection of these microhabitat characteristics must be associated with strategies to optimize the use of the reproductive habitat, based on the morphological and behavioral characteristics of the species. Finally, it is possible to infer that the differences observed in the microhabitat structure selected by the species can facilitate the coexistence of both in the context of the heterogeneity of the environment.

“…This species has reproductive activity along the whole year (Langone, 1994) but some populations use to show high reproductive activity during cold seasons (Ximenez & Tozetti, 2015). Males call from sites with dense vegetation (Santos et al, 2016) and the eggs are laid in a gelatinous mass, attached to aquatic vegetation, mainly in lentic water bodies (Maneyro & Carreira, 2012). The tadpoles are exotrophic thus having a nonspecialized behavior that can be described as a Type I reproductive mode (sensu Duellman & Trueb, 1994).…”

Density has been proposed as a factor that could determinate larval growth in anurans. We studied such effects on Boana pulchella. After hatching, we reared the tadpoles during 90 days and 93 tadpoles with similar size and developmental stages were chosen. We placed them in 800 cm 3 cans with declorified water at five densities (1, 2, 4, 8 and 16 individuals/can) with three replicates for each treatment. In all the cans the feeding was ad libitum, and they were maintained until the end of the Gosner's developmental stage 42. Each time that a tadpole was extracted, a proportional water volume was too, in order to maintain constant densities. We found significant differences among treatments for froglets' length, mandibular width and mass, while these differences were not significant for metamorphic time. Since the tadpoles were feeding ad libitum an explanation by competitive trophic interactions for that differences could be discarded. These differences could be evidence that density has significant effects.
