“…As with other species, namely H. caipora, H. ericae (Caramaschi and Cruz, 2000) and H. joaquini (Garcia et al, 2003;Antunes et al, 2008;, H. curupi physically engage in territorial disputes, a trait that is detectable due to scarring on the backs of males. Our study, however, did not observe "satellite male" behavior, which is often reported in Hylidae species (Pombal and Haddad, 2005;Oliveira et al, 2007;Miranda et al, 2008;Muniz et al, 2008). Such behavior might have exacerbated differences in perch height between calling and non-calling males.…”

Data on habitat use and life history are essential for evaluation of the conservation status of species, and may direct policy for preservation of natural environments. Over the course of a year, we investigated populations of Hypsiboas curupi regarding (i) nighttime activity patterns; (ii) associations with climatic variables; (iii) the spatial distribution patterns of males and females with respect to microhabitat use; and (iv) variation in body size. The study was carried out from August 2010 to July 2011 in the Parque Estadual Fritz Plaumann, a seasonal deciduous forest fragment in the western region of Santa Catarina, southern Brazil. Calling activity was highest from August to November. The number of calling males was highest at 23h, and the frequency of occurrence was influenced by the air humidity. Calling males, non-calling males, and females differed in their distance from the bank and substrate type used. Females were significantly larger and heavier than males. Our results indicate that H. curupi is highly dependent on bank vegetation, and that changes in riparian vegetation structure due to human activity can result in the loss of sites for calling and oviposition, and may reduce availability of food and shelter.Keywords: life history, riparian forest, stream-dwelling amphibians, seasonal deciduous forest, microhabitat use. ResumoInformações sobre o habitat e história de vida são essenciais para avaliar o status de conservação das espécies e definir ações para a preservação dos ambientes naturais. Ao longo de um ano, investigamos em populações de Hypsiboas curupi (i) o padrão de atividade noturna; (ii) relações com variáveis climáticas; (iii) o padrão de distribuição espacial de machos e fêmeas em termos de uso de microambientes; e (iv) variação no tamanho corporal. Conduzimos o estudo de agosto de 2010 a julho de 2011 no Parque Estadual Fritz Plaumann, um fragmento de Floresta Estacional Decidual na região oeste de Santa Catarina, sul do Brasil. O período de maior atividade foi de agosto a novembro. O maior número de machos vocalizando ocorreu às 23h e a frequência de ocorrência foi influenciada pela umidade do ar. Machos vocalizantes, não-vocalizantes e fêmeas foram discriminados pela distância da margem e tipo de substrato utilizado. Fêmeas foram significativamente maiores e mais pesadas do que machos. Os resultados indicam que H. curupi é altamente dependente da vegetação marginal. Assim, mudanças na estrutura da mata ciliar devido a ações humanas podem resultar na perda de sítios de canto e oviposição e reduzir a disponibilidade de alimento e abrigo.Palavras-chave: história de vida, mata ciliar, anfíbios de riachos, floresta estacional decidual, uso de microambiente.Ecology and natural history of Hypsiboas curupi (Anura, Hylidae): An endemic amphibian to the southern Atlantic Forest Ecologia e história natural de Hypsiboas curupi (Anura, Hylidae): um anfíbio endêmico do sul da Mata Atlântica Ecology and natural history of Hypsiboas curupi (Anura, Hylidae): An endemic amphibian to the so...

“…Regarding vocal and aggressive interactions, we considered males expelled from the vocalization site as losers, as well as those that remained at the site but stopped calling activity (Miranda et al 2008). Vocalizations were recorded using a Marantz PMD 660 digital recorder and a Sennheiser M66 unidirectional microphone with a K6 power module.…”

“…To reduce the interference of luminosity on the frogs' behaviour, red lights were used (e.g. Miranda et al, 2008), avoiding, whenever possible, to point the light focus directly toward the individuals. To examine some reproductive traits (see below), 21 adult males and eight females were hand-captured, anesthetized with lidocaine 10%, fixed in formalin 10%, and preserved in alcohol 70% (McDiarmid, 1994).…”

bstract. The richest anuran fauna is found in the Neotropics, but the natural history of most species is unknown. Bokermannohyla ihitiguara is a stream-dweller treefrog endemic to the Brazilian Cerrado and classified as "Data Deficient" by the IUCN. Herein we describe the species' reproductive biology. Fieldwork was conducted from August 2010 to July 2011. Reproductive activity occurred from October to June and was positively correlated with air temperature, humidity, and monthly rainfall. Individuals were observed only in gallery forests at the margins of streams and males used various kinds of substrates as calling sites. Males did not aggregate in specific parts of the streams and spatial distance between males was higher in the dry season. Males and females did not differ in length, but females without mature oocytes were lighter than males. The reproductive investment (gonad mass/body mass) of males was 0.29% and that of females was 20.26%. Female ovaries contained a mean of 202 ± 75 mature oocytes with a mean diameter of 1.96 ± 0.16 mm. We describe, for the first time for the genus, a complex courtship behaviour and also male-male fight and satellite behaviour. The Cerrado is probably the most threatened savanna in the world, having been intensively modified over the last decades. Endemic species associated to gallery forests, such as B. ibiiiguara, are highly vulnerable to habitat alterations. Thus, our study provides important data on the species' biology, which might be useful for conservation practices, but also to investigate taxonomic and phylogenetic relationships in this genus.
