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. RESUMO 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 anfíbios. Entretanto, condições de microhábitat deveriam determinar tanto onde construir um ninho quanto as variações na arquitetura do ninho. Neste estudo testamos hipóteses de seleção de microhábitats para a nidificação por sapos-ferreiros Hypsiboas faber (Wied-Neuwied, 1821), determinando características de hábitat relacionados à seleção de sítios e à arquitetura dos ninhos. O estudo foi conduzido nas margens de duas lagoas permanentes no sul do Brasil. Variáveis caracterizando o substrato e a estrutura e heterogeneidade da vegetação foram medidas em 18 parcelas com ninho e 18 parcelas adjacentes sem ninho (controle). A temperatura da água foi medida dentro do ninho e na adjacência. Atributos do ninho foram a área, a profundidade e a temperatura. Resultados demonstraram diferenças nas características de hábitat entre parcelas com e sem ninho. Parcelas com ninhos apresentaram maior cobertura e altura da vegetação, lâmina de água pouca profunda e com pouca matéria orgânica em suspensão em relação às parcelas sem ninho. Não foi observada diferença entre a temperatura dentro e fora do ninho, bem como relação entre os atributos do ninho e os descritores do habitat. Os resultados evidenciaram a seleção de hábitat para a construção de ninhos por Hypsiboas faber. Os machos parecem utilizar habitats mais protegidos, provavelmente para evitar predação, a invasão de machos coespecíficos e a ação de intempéries climáticas. A ausência de diferença entre a temperatura dentro e fora do ninho sugere que o ninho não melhora condições para o desenvolvimento dos ovos e dos girinos. A arquitetura do ninho não teve relação com fatores ambientais; comportamentos como a checagem do ninho pela fêmea antes do amplexo podem estar envolvidos. A seleção de determinados sítios para a construção de ninho deve aumentar a chance de sobrevivência da prole e o sucesso reprodutivo de Hypsiboas faber.

We present a comprehensive review of larval morphology in the Neotropical toad genus Melanophryniscus. The taxa studied included 23 species with representatives of recognized phenetic groups and different larval ecomorphological guilds: pond, stream, and phytotelm-dwelling tadpoles. Their external morphology variation is congruent with current phenetic arrangement based on adult features, but also reflects the habitat where larvae develop. Lotic tadpoles (i.e. M.tumifrons group and M.krauczuki) in general exhibit a more depressed body, a longer tail with lower fins, and larger oral discs than lentic forms (i.e. M.stelzneri group, M.moreirae, M.sanmartini, and M.langonei). Despite their peculiar, confined microhabitat, phytotelm larvae do not diverge markedly from non-arboreal species. The distinctive features of all species are the presence of a pineal end organ and the placement of the intestinal reversal point at the left of the abdomen in typical larval stages. The buccal cavity and musculoskeletal anatomy are quite conserved between species, yet some characteristics differ from those of other bufonids. The presence of one pair of subhyoid muscles is apparently an exclusive trait of Melanophryniscus among Bufonidae. Fil: Baldo, Juan Diego. Consejo Nacional de Investigaciones Científicas y Técnicas.

Aposematic signals as well as body behaviours may be important anti-predator defences. Species of the genus Melanophryniscus are characterised by having toxic lipophilic alkaloids in the skin and for presenting a red ventral colouration, which can be observed when they perform the behaviour called the unken reflex. Both the reflex behaviour and the colouration pattern are described as defence mechanisms. However, there are currently no studies testing their effectiveness against predators. This study aimed to test experimentally if both ventral conspicuous colouration and the unken reflex in Melanophryniscus cambaraensis function as aposematic signals against visually oriented predators (birds). We simulated the species studied using three different clay toad models as follows: (a) in a normal position with green coloured bodies, (b) in the unken reflex position with green coloured body and extremities and (c) in the unken reflex position with a green body and red extremities. Models were distributed on a known M. cambaraensis breeding site and in the adjacent forest. More than half of the attacks on the models were from birds; however, there was no preference for any model type. Thus, just the presence of the red colour associated with the motionless unken reflex position does not seem to prevent attacks from potential predators. It is possible that the effective aposematic signal in Melanophryniscus is achieved through the unken reflex movement together with the subsequent exhibition of the warning colouration and the secretion of toxins.

Made available in DSpace on 2022-04-29T01:26:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2011-11-01 Herein, we report karyological data for Pseudopaludicola frogs, with the main objective to investigate the confusing taxonomic identification of these anurans. The samples analyzed included topotypes of P. falcipes and P. ameghini (currently considered a synonym of P. mystacalis) in addition to specimens of P. mystacalis and P. ternetzi and of 8 additional populations of Pseudopaludicola from several regions of Brazil. Interspecific variations in the chromosome number, location of the nucleolar organizer region (NOR), and banding patterns were observed. The karyotype of P. falcipes consisted of 2n = 22 chromosomes, whereas P. ameghini (sensu Cope 1887) and P. ternetzi had 2n = 20 and P. mystacalis had 2n = 16 chromosomes. The chromosome number 2n = 16 was also found in specimens of populations from Santa Fé do Sul, Vitória Brazil, Icém, Palestina (southeastern Brazil), Barreirinhas, Urbano Santos (northeastern Brazil), Poconé, and Santa Terezinha (west-central Brazil). Nevertheless, in some individuals from Icém and Poconé, we found 2n = 20 and 2n = 22 chromosomes, respectively. This variation in chromosome number indicates diverse taxa coexisting in sympatry. The karyotypic patterns of 2n = 20 in P. ameghini (sensu Cope 1887) and 2n = 16 in P. mystacalis are clearly indicative of 2 distinct taxonomic units. Therefore, our data corroborate the removal of P. ameghini from synonymy with P. mystacalis as previously suggested. We define the karyotype of P. falcipes as 2n = 22 and of P. ternetzi as 2n = 20 and reinforce the need for a taxonomic revision of this genus.

We studied the reproductive biology of a population of Pseudis minuta Günther, 1858 from Reserva Biológica do Lami (30º 15' S; 51º 05' W), Porto Alegre, southern Brazil. We assessed the spatial and temporal distribution of individuals (males, females, juveniles) and explored potential relationships with environmental variables. Field activities encompassed bimonthly surveys in three semi-permanent ponds, each one during approximately two days and two nights, from August 2004 to July 2005. We recorded differences in the sites used by males, females and juveniles, with males occupying deeper and more distant places from the border. The temporal distributions of individuals, calling sites and amplectant pairs indicated that the reproductive activity of P. minuta is related to some of the studied abiotic factors. Calling males presented statistical differences in relation to non-calling males for all daily abiotic variables analyzed (air temperature, water temperature, relative humidity and rainfall), as well as to monthly temperature and rainfall. The number of active males, females and juveniles was influenced by at least one of the daily or monthly environmental variables analyzed. We conclude that the reproduction in this species is seasonal and may be partially determined by abiotic factors. A distribuição espacial e temporal de Pseudis minuta Günther, 1858 e fatores ambientais relacionados à atividade reprodutiva da espécie foram estudados na Reserva Biológica do Lami (30º 15' S; 51º 05' W), Porto Alegre, Brasil. As atividades de campo compreenderam visitas bimensais a três banhados semi-permanentes, com duração aproximada de dois dias e duas noites cada, entre agosto de 2004 e julho de 2005. Observaram-se diferenças nos sítios utilizados por machos, fêmeas e juvenis, com machos ocupando locais mais profundos e mais distantes da margem. A distribuição temporal dos indivíduos, vocalizações e amplexos indicaram que a atividade reprodutiva de P. minuta está relacionada com alguns dos fatores abióticos estudados. Os machos em atividade de vocalização apresentaram diferença significativa em relação aos machos não vocalizantes para todos os fatores abióticos diários analisados (temperatura do ar, temperatura da água, umidade relativa do ar e pluviosidade), bem como na temperatura do ar e pluviosidade mensais. O número de machos, fêmeas e juvenis em atividade foi influenciada por pelo menos um dos fatores ambientais mensais ou diários analisados. Conclui-se que a reprodução desta espécie é sazonal e parcialmente determinada por fatores abióticos.

We describe the advertisement and territorial calls ofHylodes meridionalisfor the first time and provide observations on nocturnal calling activity for this species. The advertisement call has 36–82 harmonic notes, with duration of 2.71–5.69 s and dominant frequency on the third harmonic. Advertisement calls are separated by large intervals varying from 18.7 to 44.7 s. The territorial call has 1–3 notes, with duration of 0.039–0.567 seconds, and dominant frequency also on the third harmonic. Territorial calls are emitted at a much higher repetition rate than the advertisement call, with intervals of 1.1–1.6 s between each call. Frogs of the genusHylodesare known to call mainly during the day, but forH. meridionalisnocturnal calling was observed on various occasions, and could occur regularly until two hours after sunset, or sporadically along the night. Descrevemos os cantos de anúncio e territorial deHylodes meridionalispela primeira vez e fornecemos observações sobre a atividade noturna de vocalização para esta espécie. O canto de anúncio tem 36–82 notas harmônicas, com duração de 2,71–5,69 segundos e frequência dominante no terceiro harmônico. Há grandes intervalos entre os cantos de anúncio, de 18,7–44,7 segundos. O canto territorial tem 1–3 notas, com duração de 0,039–0,567 segundos, e frequência dominante também no terceiro harmônico. Cantos territoriais são emitidos a uma taxa de repetição muito mais elevado do que o canto de anúncio, com intervalos de 1,1–1,6 segundos entre cada canto. As espécies do gêneroHylodessão conhecidas por vocalizar principalmente durante o dia, mas machos deH. meridionalisforam observados em atividade de vocalização noturna em várias ocasiões, sendo que podem vocalizar regularmente até duas horas após o pôr do sol, ou esporadicamente ao longo da noite.

The article explores the spatial and temporal distribution of Pseudis minuta and the role of environmental factors in its reproduction in Reserva Biológica do Lami, Porto Alegre, southern Brazil. There were significant differences in border distance and water depth among age-sex classes of Pseudis minuta. No significant difference was found in the presence of calling males and non-calling males in relation to monthly relative humidity but opposite was noted in relation to total monthly rainfall, mean monthly air temperature and water temperature. The number of females was related with daily air temperature, relative humidity and water temperature.

The article focuses on the geographic distribution extension and new state record of anura species Proceratophrys bigibbosa and Proceratophrys brauni in Brazil. It notes that P. brauni has less extensive toe webbing, smaller body size, weaker postocular cranial protuberances, and more distinctive rows of tubercles on the dorsum than P. bigibbosa. On the other hand, P. bigibbosa has a more southern distribution which ranges throughout the southern part of the country's south highlands. However, it points out that the males of both species call from streamlets of flowing water.

This study presents a preliminary evaluation of the use of the Brazilian fish Cynopoecilus melanotaenia as a test organism in toxicity tests. The cryptobiotic stage presented by the eggs of fish C. melanotaenia can overcome the difficulty of continuously keeping cultures and recruiting healthy animals in sufficient numbers to be used in toxicity tests. In order to determine the applicability of this species as a test organism, three different reference substances were evaluated in 96-h acute toxicity tests: Copper sulfate (CuSO
4 ⋅5H2 O), sodium dodecil sulfate (C12 H25 NaO4 S), and sodium chloride (NaCl). Sensitivity ranged as follows: copper sulfate (0.05-0.13 mg/L), sodium dodecil sulfate (10.7-19.0 mg/L), and sodium chloride (1.44-1.96 g/L). We conclude that C. melanotaenia shows potential as a test organism in toxicity tests; however, further research should be conducted with other substances and should be compared with the research on other species before we can reach more conclusive results.
