“…A Floresta Atlântica abriga a maior diversidade de modos reprodutivos, sendo reconhecidos 29 modos , dos quais 14 modos (36%) foram registrados na RNSM. A diversidade de modos reprodutivos na RNSM é menor que a observada em outras localidades da Floresta Atlântica stricto sensu, como por exemplo, Parque Estadual Carlos Botelho (17 modos, Forlani et al 2010), e maior que a observada no Parque Estadual da Serra do Mar, núcleo Picinguaba (10 modos, Hartmann et al 2010). No geral, a diversidade de modos reprodutivos observados nas comunidades de anuros da Floresta Atlântica stricto sensu é superior à observada em áreas de Floresta Estacional Semidecidual (e.g., Vasconcelos & Rossa-Feres 2005), e também em comparação a outros biomas, como a Amazônia (e.g., Crump 1974), Cerrado (e.g., Brasileiro et al 2005), Chaco (e.g., Perotti 1997), Pampa (e.g., Santos et al 2008), Pantanal (e.g., Prado et al 2005) e Caatinga (e.g., Vieira et al 2007).…”

Abstract:Here we present a survey of amphibian species of the Reserva Natural Salto Morato (RNSM), an Atlantic rainforest reserve in Paraná, southern Brazil. We sampled lentic and lotic water bodies, phytotelmata and leaf litter from September 2006 to March 2007. We found 42 species from nine families, one of which is endemic to the study area. Additionally, we recorded 14 reproductive modes. In the RNSM, 50% of anuran species occur in more than 50% of samples, 26% of species occurred between 25 and 50% of samples, and 24% were rare, occurring in less than 25% of samples. The reserve holds the highest diversity of amphibians and reproductive modes in Paraná. Our results emphasize the importance of RNSM for amphibian conservation. Nós registramos 14 modos reprodutivos dos anuros na área de estudo. Na RNSM, 50% das espécies de anuros ocorreram em mais de 50% das amostragens, 26% das espécies foram registradas entre 25-50% das amostragens e 24% das espécies foram raras, ocorrendo em menos de 25% das amostragens. A RNSM até o presente momento é a área com a maior diversidade de anfíbios e de modos reprodutivos do Paraná. Esses fatores evidenciam a importância da RNSM para a conservação dos anfíbios.

“…As with the majority of anurans (Hartmann, Hartmann, & Haddad, ; Wells, ), the number of eggs in C. stolzmanni increased with the size of females. This relationship has been shown to be more accentuated in explosive breeders, compared to species with prolonged reproductive seasons (Nali et al., ).…”

Random size‐assortative mating despite size‐dependent fecundity in a Neotropical amphibian with explosive reproduction

Sexual selection theory predicts that, when body size is correlated with fecundity, there should be fitness advantages for mate choice of the largest females. Moreover, because larger males are expected to monopolise the largest females, this should result in an assortative mating based on body size. Although such patterns could be expected in both explosive and prolonged breeders, non‐assortative mating should be more widespread in species under time constraints. However, patterns of sexual selection are largely unexplored in explosive breeding species, and contrasting patterns have been found previously. We expect that the active choice of partners may be particularly risky when the time period during which sexual partners are available is severely limited. Therefore, to avoid missing an entire reproductive act, males and females should pair irrespective of traits, such as body size. We tested this hypothesis by investigating the mating patterns of the Pacific horned toad, Ceratophrys stolzmanni, a short‐lived fossorial species inhabiting Neotropical dry forests. This species is particularly adequate to test our prediction because it reproduces explosively over the course of a single night per year. Although the number of eggs laid was proportional to the size of females, and individuals of both sexes showed variation in body size, there was no assortative mating based either on size, body condition or age of mates. Egg size was not influenced by either female size or clutch size. The larger body size of females compared to males is likely due to fecundity selection, that is, the selective pressure that enhances reproductive output. Although we cannot dismiss the possibility that individuals could select their partners based on other criteria than those related to size or age, the results fit well our prediction, showing that the explosive breeding makes improbable an active choice of partners in both sexes and therefore favours a random mating pattern.

“…Male gladiator frogs tend to show plasticity in where to build or to acquire a nest -according to type of substrate locally available (Höbel, 2008;Hartmann et al, 2010). Male Hypsiboas faber usually constructs almost circular nests just pushing away aquatic vegetation at pond margins (Martins, 1993a), but the species can also use pools in rock outcrops or in pre-existing depressions in sand or mud, or even re-use abandoned nests that they only have to renovate a little (Kluge, 1981;Höbel, 2008).…”

“…In the nest, a small pool of 11-21 cm depth is formed (Martins, 1993a), in which males perform advertisement and courtship calling to attract females (Martins & Haddad, 1988). After nest checking and amplexus, females deposit a surface film of ~1000 -2700 small dark eggs within the pool (Martins & Haddad, 1988;Hartmann et al, 2010).…”

ABSTRACT. Male gladiator frogs of Hypsiboas Wagler, 1830 build nests on available substrate surrounding ponds and streams where female spawn eggs during the breeding period. Although gladiator frogs seem to show plasticity in the way they construct their nests, there is no study reporting if these species present preferences about microhabitat conditions for nest-building (mainly under subtropical climate). Predation pressure and environmental conditions have been considered major processes shaping the great diversity of reproductive strategies performed by amphibians, but microhabitat conditions should explain where to build a nest as well as how nest looks. This study aimed to test nest site selection for nest-building by Hypsiboas faber (Wied-Neuwied, 1821), determining which factors are related to nest site selection and nest features. The survey was conducted at margins of two permanent ponds in Southern Brazil. Habitat factors were evaluated in 18 plots with nest and 18 plots in the surrounding without nest (control), describing vegetation structure and heterogeneity, and substrate characteristics. Water temperature was measured inside the nest and in its adjacency. Nest features assessed were area, depth and temperature. Habitat characteristics differed between plots with and without nest. Microhabitat selected for nest-building was characterized by great vegetation cover and height, as well as shallower water and lower cover of organic matter in suspension than in plots without nest. Differences between temperature inside nest and in its adjacency were not observed. No relationship between nest features and habitat descriptors was evidenced. Results revealed that Hypsiboas faber does not build nests anywhere. Males seem to prefer more protected habitats, probably avoiding predation, invasion of conspecific males and inclement weather. Lack of differences between temperature inside-and outside-nest suggest that nest do not improve this condition for eggs and tadpole development. Nest architecture was not related to habitat characteristics, which may be determined by other factors, as nest checking by females before amplexus. Nest site selection should increase offspring survival as well the breeding success of Hypsiboas faber.

Seleção de sítio para nidificação de Hypsiboas faber (Anura, Hylidae) no sul do Brasil. Machos de espécies de Hypsiboas Wagler, 1830 constroem ninhos no substrato disponível no entorno de corpos d'água; as fêmeas depositam os ovos no interior destes ninhos durante a reprodução da espécie. Embora estes machos apresentem plasticidade na escolha de sítios para construção dos ninhos, ainda não existem avaliações de preferências por condições específicas de microhabitat para a nidificação (principalmente em clima subtropical). A pressão de predação e as condições ambientais são consideradas os principais processos moldando a diversidade de estratégias reprodutivas em...
