Abstract This study aimed to carry out a taxonomic floristic survey of species in the genus Ditassa (Asclepiadoideae/Apocynaceae), as part of the “Flora do Ceará: knowing to conserve” project. The study was based on the analysis of morphological characters of specimens from representative herbaria for the genus. The identifications were performed using specialized bibliography and confirmed by analyzing type collections. For Ceará state, six species of Ditassa were registered: D. blanchetii, D. capillaris, D. dardanoi, D. glaziovii, D. hastata and D. hispida. The species occur in Savana (Cerrado), Stepic Savanna (Caatinga/Carrasco), Dense Ombrophilous Forest (Wet forest) and Lowland Semideciduous Seasonal Forest (Tableland forest). Only D. capillaris and D. hastata were recorded in Conservation Units.

Abstract We performed the taxonomic-floristic survey of subtribe Gonolobinae for the state of Ceará, as part of the “Flora do Ceará: knowing to conserve” project. The study was based on the comparative analysis of morphological characters, specialized bibliography, as well as photos of type-collections. In Ceará, six species of two genera were registered: Gonolobus rostratus, Matelea denticulata, M. endressiae, M. ganglinosa, M. harleyi, and M. nigra. Matelea ganglinosa has a broad distribution in the state, while G. rostratus, M. denticulata and M. endressiae are restricted. Matelea species were recorded in six Conservation Units and preferably dry environments (Stepic Savanna, Seasonal Deciduous Forest, and Lowland Semideciduous Forest).

Serra da Pedra Branca (SPB) is a mountain range located in the Southwestern portion of the state Minas Gerais, in the municipality of Caldas (21°58′-21°55′S, 46°24′-46°22′W). It is a striking feature in the landscape, between 1100 and 1780 m.s.m., in a region that is part of the Atlantic Forest Domain and is considered as a priority area for conservation of the flora in Minas Gerais state. The vegetation is composed by a mosaic of “campo de altitude” (which occupy the greatest extension in the area), Seasonal Semidecidual Montane Forest, Dense Ombrophilous High-Montane Forest and Mixed Ombrophilous Forest. The aims of this study was the elaboration of a floristic survey of SPB added to the specimens collected by Anders Fredrik Regnell in the nineteenth century in Caldas and to analyze its floristic similarity with altitude areas of the Southeastern Region of Brazil. There were recorded 502 vascular plant species, distributed in 274 genera and 100 families. The majority of recorded species present herbaceous habit, terricolous, saxicolous and/or rupicolous (representing around 58% of recorded species), predominantly occurring in the “campo de altitude” (ca. 46%). The richest families were Polypodiaceae (20 spp.) and Dryopteridaceae (10 spp.) among the ferns, and Orchidaceae (56 spp.), Asteraceae (27 spp.) and Fabaceae (26 spp.) among the angiosperms. Just one species of gymnosperm was recorded, Araucaria angustifolia (Bertol.) Kuntze (Araucariaceae). Five new records were made for the Minas Gerais flora, 13 species are cited as threatened with extinction in the state and at least six are endemic to SPB. Amongst 127 species collected in XIX century in the region, only 29 collected again, while 375 new records were made for SPB. The analysis of floristic similarity performed between the flora of SPB and other altitude areas of Southeastern Region revealed isolation of SPB in relation to other areas, highlighting its floristic peculiarity, which can probably be explained by its location in a distinct hydrographic basin. The vegetation of the SPB must be considered as endangered since the presence of endemic species and/or threatened species, associated with local environmental conditions suffering accelerated rate of destruction, highlight the need for urgent actions to preserve local biodiversity.

The parasitoid wasps Belytinae (Hymenoptera: Diaprioidea: Diapriidae) recorded thus far in the Atlantic Dense Ombrophilous Forest are reviewed at the supra specific level. The knowledge about the diversity of Belytinae in the Atlantic Forest is relatively poor, although these parasitoids may play a key role in the natural regulation of populations of the Mycetophilidae and Sciaridae (Diptera). The material used in this study comes mostly from standardized collections in 18 regularly spaced sites, from Paraíba to Santa Catarina Brazilian states, between 2000 and 2002, by the project “Richness and diversity of Hymenoptera and Isoptera along a latitudinal gradient in the Atlantic Forest – the eastern Brazilian rain forest” (Biota/SP – FAPESP). At each location ten Malaise traps and a hundred Moericke traps were installed, both along two parallel transects spaced 100 m from each other. Further, a similar effort for the sweeping of vegetation was applied at each locality, being each sweeping sample the result of 5 minutes of sweeping. Traps, and sweeping of vegetation in the summed localities yielded a total of 1,241 Belytinae specimens, of which we recognize 115 morphospecies in eight genera (Aclista, Belyta, Cinetus, Odontopsilus, Scorpioteleia, Lyteba, Tropidopsilus and Camptopsilus). A further belytine genus (Miota), recorded in similar environment, was found at the collection of the Federal University of Espírito Santo and added to the list, totalling nine here keyed genera; for each genus we include a diagnosis, comments and a discussion on its records, distribution and biology; we also provide twenty-two plates with 102 figures (93 photographs and 9 maps).

Este trabalho teve como objetivo analisar a estrutura fitossociológica horizontal de um trecho da vegetação arbórea de uma floresta de tabuleiro. Foi realizada uma amostragem fitossociológica em 100 parcelas contíguas de 10 x 10 m, sendo amostrados os indivíduos com PAP ≥ 15 cm. Construiu-se a distribuição diamétrica e estimou-se o padrão de distribuição espacial das espécies. Foram amostrados 1519 indivíduos, distribuídos entre 265 espécies, 138 gêneros e 44 famílias. O índice de Shannon (H’) estimado foi de 4,87 nats/ind. As espécies com os maiores VI foram Rinorea bahiensis (Moric.) Kuntze, Eriotheca macrophylla (K. Schum.) A. Robyns e Sterculia speciosa K. Schum. Em relação aos grupos ecológicos, as secundárias tardias obtiveram mais que o dobro do VC e VI das secundárias iniciais. A distribuição diamétrica apresentada pelas pioneiras foi truncada, sendo que a das secundárias iniciais foi ampla. A predominância de espécies tolerantes ao sombreamento nos estágios iniciais de crescimento reforça a ideia de que o estádio sucessional encontra-se avançado. Foram encontradas 10 espécies com padrão de distribuição espacial agregado e 29 aleatório.Palavras-chave:Fitossociologia; estrutura horizontal; Floresta Ombrófila Densa; floresta de tabuleiro; floresta atlântica. AbstractHorizontal structure of Ombrophilous dense forest of lowlands in Sooretama Biological Reserve, Linhares. This work aimed to analyze horizontal structure of arboreal vegetation from a “tableland” forest. A phytosociological sample was carried out on 100 contiguous plots of 10 X 10 meters. We sampled the individuals with PBH ≥ 15 cm, built up the diametric distribution and estimated spatial species distribution pattern. We sampled 1519 individuals, which were distributed into 265 species, 138 genera and 44 families. Shannon’s Index (H’) was estimated at 4.87 nats/ind. Species with the highest IV were Rinorea bahiensis (Moric.) Kuntze, Eriotheca macrophylla (K. Schum.) A. Robyns and Sterculia speciosa K. Schum. In relation to ecological groups, the late secondary species obtained CV and IV, twice as much as the early secondary ones. Pioneers presented truncated diametric distribution, as long as the early secondary had a broader one. Shadow tolerant species predominance reinforces that successional stadium is advanced. It had been found 10 species with aggregated spatial distribution and 29 random ones.Keywords:              Phytosociology; horizontal structure; Dense Ombrophilous Forest; tabuleiro forest; atlantic forest.

Abstract The bryoflora of Brazil comprises 1,524 species, 117 families, and 413 genera (11 hornworts, 633 liverworts, and 880 mosses). The most diverse families of liverworts are: Lejeuneaceae (285 species), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae and Metzgeriaceae (26 each), Lophocoleaceae (18), Aneuraceae (15), and Calypogeiaceae (13); while, for the mosses, we have: Sphagnaceae (83 species), Fissidentaceae (65) Pottiaceae (63), Dicranaceae (54), Bryaceae and Sematophyllaceae (53 each), Orthotrichaceae and Pilotrichaceae (51 each), Calymperaceae (48), and Hypnaceae (28). These large groups account for 71% of the Brazilian bryophyte species. Lejeuneaceae and Sphagnaceae are the families with highest number of endemic taxa (54 and 60 species). The Atlantic Rainforest presents the greatest number of species (1,337), followed by the Amazon Rainforest (570) and Cerrado (478). The highest number of endemic species (242) is associated with the Atlantic Rainforest, where the Dense Ombrophilous Forest concentrates 73% of the species with 62% endemism. The Southeastern region is the most diverse in number of species (1,228) and with more endemism (219). Most endangered species are restricted to the Atlantic Rainforest of southeastern Brazil, which is the diversity and endemism centre for mosses and liverworts. The information currently presented by the Brazilian List is close to the real bryophyte diversity found in the country.

An unusual new species of Eremocaulon, a Neotropical woody bamboo genus, is here described and illustrated. Eremocaulon triramis occurs in dense ombrophilous forest and is apparently endemic to Espírito Santo state, Brazil. The diameter and indument of the culms, number of branches in the branch complement, and occurrence of two different forms of fimbriae on the foliage leaves allow this taxon to be recognized as distinct from its congeners, even in the vegetative condition. Reproductively, E. triramis differs from its congeners in having laminiferous subtending bracts in the pseudospikelets and four stamens. Illustrations, photos, a detailed description, comments on morphology, habitat, distribution, and conservation status are provided, as well as a key to all species of Eremocaulon.

The "Serra do Mar" region comprises the largest remnant of the Brazilian Atlantic Forest. The coast of the Paraná State is part of the core area of the "Serra do Mar" corridor and where actions for biodiversity conservation must be planned. In this study we aimed at characterizing the landscape structure in the APA-Guaraqueçaba, the largest protected area in this region, in order to assist environmental policies of this region. Based on a supervised classification of a mosaic of LANDSAT-5-TM satellite images (from March 2009), we developed a map (1:75,000 scale) with seven classes of land use and land cover and analyzed the relative quantities of forests and modified areas in slopes and lowlands. The APA-Guaraqueçaba is comprised mainly by the Dense Ombrophilous Forest (68.6% of total area) and secondary forests (9.1%), indicating a forested landscape matrix; anthropogenic and bare soil areas (0.8%) and the Pasture/Grasslands class (4.2%) were less representative. Slopes were less fragmented and more preserved (96.3% of Dense Ombrophilous Forest and secondary forest) than lowlands (71.3%), suggesting that restoration initiatives in the lowlands must be stimulated in this region. We concluded that most of the region sustains well-conserved ecosystems, highlighting the importance of Paraná northern coast for the biodiversity maintenance of the Atlantic 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.
