O estado da arte das vocalizações de anfíbios anuros da Mata Atlântica

The vocals are the most conspicuous means of communication between frogs and can express evolutionary relationships among species. Call descriptions of frogs, in general, not standard acoustic parameters which are greatly diversified and usually restricted to comparisons between closely related taxa. The Atlantic Forest is considered one of the biodiversity hotspots of the world, however, it appears that the number of species to be known is still very large. To anurans from this Brazilian Domain, vocalizations are complex and can vary intra and interpopulations. Thus, we presented a quantitative and qualitative analysis of the work descriptions of anuran advertisement call from the Atlantic Forest, available in the literature so far. The frog species from this Domain and their descriptions of the advertisement call have been raised in the literature, organized into families and threat category IUCN Red List Threatened Species. The analysis of the descriptions were made based on the presence of preset parameters. It was observed that the species which the advertisement call is described within the standard are expected within the Brazilian Atlantic Domain, but efforts to describe the advertisement call of frogs of the Atlantic are concentrated in non-threatened species. Among the descriptions works, there is a large discrepancy between the information presented, giving preference to the use of abiotic data in this kind of work, to the detriment of biotic data about choir where the songs were recorded. The results point to the need for advancements in the descriptions of the advertisement of endangered species or to those with deficient information on their conservation status in the Atlantic Forest, and also for greater communication between works that describe vocalizations of frogs. It will be important to know about the state of the art of descriptions works of frogs in other Brazilian Domains, and relate this information with knowledge...

Platinosomíase em felinos domésticos: um diferencial para obstrução biliar

The platinosomiase is a disease the hepatobiliary system of domestic felines being caused by trematode Platynosomum fastosum. The life cycle of the parasite includes the presence of three intermediate hosts (snails, terrestrial isopodes, lizards or frogs). The cat is considered definitive host of the parasite and acquires the infection eating a vertebrate intermediate host containing metacercariae. The adult parasites generally inhabit the liver, gallbladder and bile ducts of cats. The severity of clinical manifestations depends mainly on the number of flukes in the biliary tract. Many animals are asymptomatic or exhibit nonspecific clinical manifestations such as anorexia, lethargy, weight loss, vomiting and diarrhea. In large infestations can occur biliary obstruction resulting in jaundice, cirrhosis, hepatitis cholangiohepatitis and even death. The definitive diagnosis is accomplished through by the detection of fluke eggs in feces or through laparotomy and liver biopsy. Treatment should be based on the use of anthelmintic for the elimination of the parasite and supportive therapy for the animal. Prevention is difficult due to predatory nature of the cat. The control can be accomplished through periodic fecal examinations

História natural de Hypsiboas albopunctatus (Anura: Hylidae) na região de Rio Claro, estado de São Paulo

Natural history studies aim to know where the organisms live, what they do, and their relationships within the environment, including the other organisms. The anurans, among other vertebrates, exhibits the greatest variety of reproductive modes as well as a high complexity of social organization, that may enable a lot of naturalist studies. Anurans modes of organization are direct related to parental care, vocalization of chorus organization, and with males territoriality. In general, the social organization is influenced by species reproductive pattern. This study aim to get information about the natural history of Hypsiboas albopunctatus (perereca-cabrinha) a species of the family Hylidae, on the region of Rio Claro Municipality, São Paulo State, Brazil. The major aspects discussed were: seasonality, spatial distribution, acoustic and visual communication, reproductive mode, reproductive site, abiotic factors influences, territoriality, courtship behaviour, satellite male behavior, embrace and defensive behavior. To obtain this data, nocturnal field excursions were realized monthly. Two sites of Rio Claro county where chosen as studies sites, the sítio Cantaclaro (22o19’36’’S; 47o42’57’’O), on the District of Itapé and Floresta Estadual Edmundo Navarro de Andrade (FEENA) (22o24’58’’S; 47o31’26’’O).

O coro em O díscolo de Menandro

There is a consensus among scholars that the chorus in Menander’s time had become totally detached from stage-action; its performances, marked in the Greek text by the word ΧΟΡΟΥ, separated like interludes the acts from each other within the plays; the chorus had a technical function: provide a break in the action to cover certain off-stage events and indicate the passing of time. This paper, however, examines in Dyskolos, one of Menander’s early comedies, the relation between the chorus and Cnemon present in the old man’s words that makes generalizations about human relationships, and shows that in this comedy the chorus of the followers of the god Pan was exploited by the poet as a source of achieving various dramatic effects.

Anuran skin and basking behavior: the case of the treefrog Bokermannohyla alvarengai (Bokermann, 1956)

We investigated the morphology of the skin and the biochemistry of the lipids in the skin secretion of Bokermannohyla alvarengai, a montane treefrog that is known to bask regularly, motionless in full sunlight for extended periods of time. Our primary goal was to identify structural and biochemical modifications that might assist this frog species to accommodate the conflicting demands for heat exchange and water balance while basking. The modulation of heat exchange in basking B. alvarengai involves changes in skin coloration. We found that this response was supported by a prominent monolayer of large iridophores, whose light reflectance property is adjusted by the response of intervening melanophores. Mucosubstances and lipid compounds, mainly consisted of saturated fatty acids and presumably secreted from granular glands, were detected on the skin of B. alvarengai. These compounds formed an extra-epidermal layer over the animal's dorsal surface that might assist in the prevention of excessive water loss through evaporation. Additionally, we found well-developed skin folds at the ventral region of the frogs that lead to an increment of surface area. This feature combined with the extensive hypervascularization, also noticed for the skin of B. alvarengai, may play an important role in water reabsorption. The suite of structural and biochemical modifications identified for the integument of B. alvarengai seems to conjugate aspects relevant to both, heat exchange and water balance, allowing for this species to explore basking as an efficient thermoregulatory strategy.
