All life stages of Stenochironomus atlanticus Pinho & Mendes sp. n. are described and figured. The larva mines decaying leaves held in the water of several bromeliad species (Canistrum lindenii (Regel) Mez, Neoregelia laevis (Mez) L.B. Smith, Nidularium innocentii Lemaire, Vriesea philippocoburgii Wawra, and Vriesea vagans (L.B. Smith) L.B. Smith.) in the Atlantic Rain Forest in southern Brazil [Desterro Environmental Conservation Unit (Unidade de Conservação Ambiental Desterro – UCAD), Santa Catarina Island]. Stenochironomus atlanticus is the only species in the genus found in the phytotelmata habitat, and it apparently is restricted to this environment.

Abstract We present a checklist for the ferns and lycophytes from Pico Paraná State Park, in Southern Brazil. The Park is entirely located at the Serra do Mar mountains, and represents an important remnant of the Atlantic Rain Forest with altitude achieving 1,887 m. In this locality is the Pico Paraná, the highest mountain in Southern Brazil. This study was focused on the altitudes above 1,000 m, which are mainly represented by dwarf forests and altitudinal fields. A total of 142 species were recorded, three of them (Ceradenia maackii, Diplazium tamandarei, and Stenogrammitis wittigiana) are only found in the park in Southern Brazil. Besides of the checklist of the species, we highlight some important aspects related to endangered species, geographic distribution, and life forms. The high level of endemism, the presence of endangered species, and the phylogenetic diversity as represented by distinct families of ferns and lycophytes show the biogeographic importance of this area for the conservation of these groups of plants.

Nigrohydnum nigrum Ryvarden is a rare polypore previously known only from two records in Brazil. During a herbarium revision at SP we have identified an old voucher specimen, extending the previously known geographic distribution to the Atlantic rain forest of Porto Alegre, Rio Grande do Sul State, Southern Brazil.

Abstract: The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where they often occur in sympatry. There is a large gap in the knowledge of natural history of both species. In this study, we aimed to describe and compare the diet composition of B. bischoffi and B. marginata in the southern domain of the Brazilian Atlantic Forest. We analyzed the gastrointestinal contents of 43 individuals of B. bischoffi and 30 individuals of B. marginata. Both showed a high trophic niche overlap (0.90 Ojk). The most important prey categories for both species belonged to the orders Araneae and Coleoptera. The species niche breadth (Bsta) varied from 0.35 to 0.42, suggesting a generalist feeding behavior for both species. Our data provide unprecedented information on these species' food composition, contributing to a better knowledge of the natural history of neotropical anurans.

Male speci-mens were collected with CDC light traps in the Biological Reserve of Augusto Ruschi, municipality of Santa Teresa, state of Espírito Santo, Brazil. This finding raises the number of described Western Hemisphere Sycorax species to 15.

The Relationship

The reciprocal importance of bromeliads and hummingbirds has been proposed for many years, even suggesting coevolution between these two groups. Nevertheless, data are lacking that allow a better test of the relationships involved. Here we investigate the relationship between bromeliads and hummingbirds in an area of secondary Atlantic rain forest in southern Brazil. The study examined the interactions among 12 species of bromeliad and 10 of hummingbird at Reserva Natural Salto Morato, Paraná state. The number of flowering species of bromeliad and the species richness and abundance of hummingbirds were quantified monthly between November 2004 and October 2005. Focal observations on each bromeliad species were made to determine the hummingbird visitors. Neither species richness nor abundance of hummingbirds were related to bromeliad phenology. Together with the monthly variation in visit frequency by a given pollinator to a given plant, these factors indicate a generalization in the use of bromeliads by hummingbirds and argue against tight coevolution. Ramphodon naevius and Thalurania glaucopis were the main pollinators in the community. Aechmea nudicaulis was the most generalist bromeliad species. The generalist species interacted with other generalists or with asymmetric specialists and there was no specialist–specialist interaction. This produced a strongly organized and nested matrix of interactions. This nestedness is similar to other plant-pollinators networks, supporting the hypothesis that the evolutionary relationship between bromeliads and hummingbirds is no stronger than that of other pollination networks.

Ombrophilous Forest

A floristic survey of pteridophytes (ferns and fern allies) was carried out in a 1ha plot in the Pico do Marumbi State Park, Morretes, State of Paraná, Southern Brazil. The study area is covered with a closed ombrophilous forest (Brazilian Atlantic Forest) and lies approximately 630 m in elevation. All species and life-forms of pteridophytes growing in the plot were registered and most of them were collected for taxonomic identification. A total of 81 species, belonging to 17 families were registered. The richest were Polypodiaceae (12 species), Hymenophyllaceae (11) and Lomariopsidaceae (11). The richest genera were Asplenium (ten species), Elaphoglossum (10) and Trichomanes (six). Life-form composition was: epiphytes (49 species), terrestrials (28), lithophytes (two), epiphytes/terrestrials/lithophytes (one) and epiphytes/lithophytes (one). No hemiepiphytes were found. Terrestrials included herbaceous (22 species), arborescent (four) and climbing (two). Species richness of the plot can be considered as high when compared to other neotropical sites.
