Tropidodryas serra is an endemic snake from the Brazilian Atlantic Forest and despite its wide distribution, little is known about its ecology. Tropidodryas serra is an oviparous snake, but there are few available data on its  reproductive cycle. In this paper, we present the first report of oviposition of T. serra in captivity with successfully hatching. A pregnant female was captured in the area of Non-Governmental Organization (NGO) Dacnis Project, Ubatuba-SP, southeastern Brazil, and held captive. The spawning of 7 eggs and the development of offspring were observed. The eggs (measuring 4x1.35 cm in average) hatched in 90 days, with 6 healthy neonates and 1 stillborn. Based on a unique successful hatching of T. serra eggs in captivity, the present study confirmed with naturalistic data reproductive characteristics of the species, such as egg laying in December and low number of atresic eggs, corroborating that the species should present few reproductive events and concentrated throughout the rainy season.

Selection Of

Rocky seashores are low granitic hills distributed along the southeastern Brazilian coast with xeric-like vegetation due to the shallow soil. Knowledge on amphibian communities and their reproductive patterns is especially reduced on this kind of environment. Herein, we present a framework of two years monitoring an amphibian community at a rocky seashore environment located at the protected area of Parque Estadual da Serra da Tiririca, municipality of Niterói, state of Rio de Janeiro, Brazil. We conducted diurnal and nocturnal searches for frogs in tank bromeliads, rocky surface and shrubby vegetation. Annual pattern of breeding activity of anurans was also estimated. Individuals of the most abundant tank-bromeliad, Alcantarea glaziouana were collected and measured according to several variables to understanding the selection of bromeliads by frogs. We checked the influence of the environmental conditions on amphibian abundance, association between the bromeliads measures, and the water storage in the tank. We recorded the species: Scinax aff. x-signatus; S. cuspidatus; S. littoreus; Thoropa miliaris and Gastrotheca sp. Bromeliads were the preferential habitat used by anurans. The nocturnal habit was predominant for all species and during diurnal searches, the specimens were found sheltered in bromeliads axils. The number of calling males as well as amphibian abundance was associated with the rainiest and warmest period of the year. The species S. littoreus was observed in breeding activity in the majority of sample period. Adult calling males of T. miliaris were observed especially in the rainy season. Rainfall and temperature combined are positively correlated to the total number of captured amphibians. However, individually, rainfall was not significantly correlated, while temperature was positively correlated with the amphibian abundance. Water storage capacity by bromeliads was correlated to characteristics and size of the plant. In the rainy season, the height of the plant and the diameter on top view were correlated with the occurrence of amphibians, while during the driest period there was no correlation among variables and the bromeliad usage by amphibians. Recorded species were strongly associated to the Atlantic Forest domain. Nevertheless, the occupation of rocky seashores by anurans may be more associated with the specialized reproductive modes presented by species, since there is no permanent water available in ponds or streams.

Abstract In the present study, I propose a new species, Quararibea bovinii, an Atlantic Forest tree. The new taxon occurs in southeastern Brazil, in the states of Espírito Santo, Rio de Janeiro, and São Paulo. It resembles Q. similis in terms of floral morphology and fruit shape, but it is distinguished by the indumenta of leaves, leaf width, and seed shape.

Two New Species

Two new species of Myrcia from the Atlantic rainforest in southeastern Brazil, Myrcia congestiflora and Myrcia longipaniculata are here described and illustrated. Myrcia congestiflora occurs in São Paulo and Rio de Janeiro states and is similar to Myrcia cerqueiria, differing by having densely sericeous indumentum (versus sparse and shorter trichomes), larger flowers and flower buds (flower buds with 3–4 mm versus 1.1 mm long) and by acute or obtuse calyx lobes rather than rounded. Myrcia longipaniculata is known for one collection from the boundary of São Paulo and Rio de Janeiro differing from Myrcia spectabilis mainly by the longer inflorescence size (29 cm versus 3.5–21.5 cm long.) as well as for presenting a strong reddish or ferruginous indumentum (versus brown to yellowish).

Rhagomys rufescens is a rare, arboreal sigmodontine rodent endemic to the Brazilian Atlantic Forest biome. This species is known from eight localities in Brazil. Here we present a new report based on four individuals of this species registered in Serra do Ouro Branco, municipality of Ouro Branco (Minas Gerais, Brazil). One juvenile male, one adult male and two juvenile females were captured in pitfall traps during the rainy season, in a study of small mammal ecology. This is the first record for the Espinhaço Mountain range and the northernmost report for the species in this state, 85 km northeast of the last registered location.

In recent years haemosporidian infection by protozoa of the genus Plasmodium and Haemoproteus, has been considered one of the most important factors related to the extinction and/or population decline of several species of birds worldwide. In Brazil, despite the large avian biodiversity, few studies have been designed to detect this infection, especially among wild birds in captivity. Thus, the objective of this study was to analyze the prevalence of Plasmodium spp. and Haemoproteus spp. infection in wild birds in captivity in the Atlantic Forest of southeastern Brazil using microscopy and the polymerase chain reaction. Blood samples of 119 different species of birds kept in captivity at IBAMA during the period of July 2011 to July 2012 were collected. The parasite density was determined based only on readings of blood smears by light microscopy. The mean prevalence of Plasmodium spp. and Haemoproteus spp. infection obtained through the microscopic examination of blood smears and PCR were similar (83.19% and 81.3%, respectively), with Caracara plancus and Saltator similis being the most parasitized. The mean parasitemia determined by the microscopic counting of evolutionary forms of Plasmodium spp. and Haemoproteus spp. was 1.51%. The results obtained from this study reinforce the importance of the handling of captive birds, especially when they will be reintroduced into the wild.

Here, we propose Uanauna gen. nov. (Lampyridae: Photinini), a new monotypic genus of fireflies endemic to the Brazilian Atlantic Forest. Uanauna angaporan sp. nov. occurs in Submontane and Montane forest habitats at the Serra do Mar mountain range, in the Southern Fluminense region (Rio de Janeiro State, Southeastern Brazil). The new species was recorded both on the mainland, at the municipality of Itaguaí and Rio de Janeiro, and at the continental island of Ilha Grande, in Angra dos Reis, at the Rio de Janeiro State. An occurrence map and illustrations of diagnostic features are given for the new taxa, as well as a key to Lucidotina genera in Brazil.

ABSTRACT This study investigates the flowering and pollinators of the floral morphs of three co-occurring distylous species, Psychotria conjugens Müll, P. hastisepala Müll. Arg. and P. sessilis Vell., in two consecutive flowering seasons in an Atlantic Forest fragment in southeastern Brazil. The species have diurnal, cream-colored, tubular, nectariferous flowers and their flowering occurs in the rainy season, from September to April, with little or no overlapping between species, characterizing a staggered flowering. The flowering of the long-and short-styled floral morphs of each species was synchronous, but the number of open flowers per day per morph tended to vary in each flowering season. These numbers were higher in P. sessilis and P. conjugens and, probably, resulted in higher total numbers of visits on its flowers (up to 1084 visits in P. sessilis and 756 in P. conjugens), compared to that observed in P. hastisepala (up to 71). There was a higher frequency of visits to long-styled flowers of all species. The bee Ariphanarthra palpalis was a common pollinator to all species. This bee is native to Brazil, solitary, considered relatively rare and its host plants were unknown. Other native bees (Melipona spp.) also visited the flowers of the Psychotria species. The availability of flowers with similar floral features over eight months, the staggered flowering and common pollinators appear to be part of a strategy to attract floral visitors, minimizing the competition for pollinators and then favoring the legitimate pollination of these plants.
