Asteraceae in the northern Espinhaço Range, Brazil: richness, endemism and conservation Acta Botanica
Staudt,Mariana Guerra; Alves,Maria; Roque,Nádia.
ABSTRACT Floristic inventories focussing on the Espinhaço Range have revealed an extensive diversity for Asteraceae and emphasize the high degree of endemism of its species. This study aims to explore the species-rich Asteraceae through a floristic survey, and by identifying endemic records for the municipality of Morro do Chapéu, Bahia. Samples were collected during six field trips in different phytophysiognomies and approximately 1,400 exsiccatae from the main herbaria collections were examined. Asteraceae in Morro do Chapéu is represented by 18 tribes, 72 genera and 119 species. Eupatorieae and Vernonieae are the most species rich tribes and currently comprise 30 and 28 species, respectively, representing 50 % of the local Asteraceae flora. Baccharis...

Check-list of the Family Lamiaceae in Pernambuco, Brazil BABT
Almeida,Cecília de Fátima C. B. R. de; Albuquerque,Ulysses Paulino de.
A survey of the family Lamiaceae in the state of Pernambuco revealed the presence of 20 genera encompassing 46 species. The genera with the highest number of exsiccatae were Hyptis and Ocimum; others had little representative material, and some taxa were collected only once. Regarding the phytogeographical distribution in the state, 9.1% of the registrations of species occurred in the coastal zone, 54.5% in the forest zone and 36.3% in the caatinga zone.

Floristic survey of the herbaceous-shrub layer of a gallery forest in Alto Paraíso de Goiás - GO, Brazil BABT
Chaves,Eduardo; Soares-Silva,Lucia Helena.
Flowering species of the herbaceous and shrubby layer were sampled in a gallery forest at Portal da Chapada, Alto Paraíso de Goiás-GO in the Chapada dos Veadeiros during 12 months growing within 4.5 meters on either side of a raised pathway 2.4 Km long. The collections were included to University of Brasilia Herbarium (UB). A total of 138 species (103 genera and 40 families) were recorded; the most species-rich families were Asteraceae (22), Poaceae (14), Rubiaceae (12), Fabaceae (11) and Melastomataceae (7). The richest family in number of genera was Asteraceae (19), followed by Poaceae (8), Fabaceae (8) and Rubiaceae (7). The results showed a meaningful increase in the Chapada dos Veadeiros flora, especially considering the herbaceous-shrubby layer of...

Inventory of Ferns and Lycophytes of the RPPN Pedra D'Antas, Pernambuco state, northeastern Brazil Biota Neotropica
Farias,Rafael; Silva,Ivo; Pereira,Anna Flora; Santiago,Augusto; Barros,Iva.
Abstract The Northeastern Atlantic Forest (NAF) has a historic of intense habitat loss and fragmentation. In this context, knowledge of the species from forest remnants is urgently needed and represents a key tool for future studies and conservation strategies. Here, we present the floristic inventory of ferns and lycophytes from the Private Natural Heritage Reserve - RPPN Pedra D'Antas, located in a NAF area. The study area associated with the RPPN Frei Caneca is the Serra do Urubu, which is a hotspot for the diversity of several biological groups in the NAF. We recorded 74 fern species, distributed in 17 families and 46 genera. The most diverse families were Pteridaceae (17 species), Polypodiaceae (14 spp.), Dryopteridaceae (nine spp.) and...

Melliferous flora and pollen characterization of honey samples of Apis mellifera L., 1758 in apiaries in the counties of Ubiratã and Nova Aurora, PR Anais da ABC (AABC)
SEKINE,ELIZABETE S.; TOLEDO,VAGNER A.A.; CAXAMBU,MARCELO G.; CHMURA,SUZANE; TAKASHIBA,ELIZA H.; SEREIA,MARIA JOSIANE; MARCHINI,LUÍS C.; MORETI,AUGUSTA C.C.C..
The aim of this study was to carry out a survey of the flora with potential for beekeeping in the counties of Ubiratã and Nova Aurora-PR through the collection of plants and pollen analyses in honey samples collected monthly. 208 species of plants were recorded, distributed in 66 families. The families that showed the major richness of pollen types were: Asteraceae, Myrtaceae and Solanaceae. Approximately 80 pollen types were found in honey samples, most of them were characterized as heterofloral. Cultivated plants, such as Glycine max (soybean) and Eucalyptus spp., were representative in some months of the year. Exotic species, such as Ricinus communis and Melia azedarach, were also frequent. However, over than 50% of the pollen types belong to native...

Cavalcanti,Laise de Holanda; Bezerra,Andrea Carla Caldas; Costa,Antônia Aurelice Aurélio; Ferreira,Inaldo do Nascimento; Bezerra,Maria de Fátima de Andrade.
Order Ceratiomyxales, which belongs to subclass Ceratiomyxomycetidae, includes the exospore bearing Myxomycetes, solely comprising family Ceratiomyxaceae and genus Ceratiomyxa, with four species. Based on the literature, on herbarium collections, and on recent surveys carried out by the authors in different states and ecosystems, it was possible to determine the occurrence and distribution of C. fruticulosa (cosmopolitan),C. morchella and C. sphaerosperma (predominantly tropical or subtropical) in northeastern Brazil. Species descriptions and illustrations are presented, as well as a map of their geographical distribution in eight of the nine states of Northeast Brazil. This order is being recorded for the first time for the state of Sergipe. Ceratiomyxa...

Phytoplankton of two rivers in the eastern Amazon: characterization of biodiversity and new occurrences Acta Botanica
Cunha,Elane Domênica de Souza; Cunha,Alan Cavalcanti da; Silveira Jr,Arialdo Martins da; Faustino,Silvia Maria Mathes.
During the various hydrological periods in 2011, we studied the phytoplankton along an 87-km stretch of the Araguari and Falsino rivers, which are located in the eastern Brazilian Amazon, in the state of Amapá, Brazil, the most ecologically preserved state in the country. In the study area, the aquatic ecosystem is under pressure from human activities such as, mining, hydroelectric power generation and urbanization, which contrast with the surrounding areas that are designated for biodiversity conservation. The aim of this study was to characterize the composition, frequency and richness of algae species and also to identify spatial-temporal patterns of taxa distribution. During the study period, we identified 185 taxa (136 species in 49 genera). The...

The Floristic and Forest Inventory of Santa Catarina State (IFFSC): methodological and operational aspects PFB - Pesquisa Florestal Brasileira
Vibrans, Alexander Christian; Sevgnani, Lúcia; Lingner, Débora Vanessa; de Gasper, André Luis; Sabbagh, Shams.
The purpose of this study is to contribute to the discussion on regional and national forest inventories, aiming mainly on aspects of methodos and operational. The Floristic and Forest Inventory of Santa Catarina State (IFFSC) is an initiative of the state government and it was conceived in order to attend requirements of environmental laws. A pilot inventory took place in  2005; then the methodology was fitted to the proposal of the National Forest Inventory (IFN-BR) in discussion at the time. IFFSC is carried out since 2007 in all natural forest formations all over the state’s territory, including floristic sampling (collection of fertile trees, shrubs and herbs within the sample unit and in its surroundings) and survey of vascular epiphytes by...

Three new species of Sloanea L. (Elaeocarpaceae) from the Central Amazon, Brazil Rev. Bras. Bot.
Boeira,Amanda Shirléia Pinheiro; Vicentini,Alberto; Ribeiro,José Eduardo Lahoz da Silva.
Three new species of Sloanea L. are recognized based on specimens collected in the Adolpho Ducke Forest Reserve. These new species are morphologically distinct from other Sloanea in the Neotropics in terms of their vegetative and reproductive characters. The Ducke Reserve contains a total of 18 species of Sloanea, and the species closest to these new taxa occur there. Morphological descriptions and illustrations are provided, together with comments concerning morphological similarities with other species, as well as their geographic distributions and their phenologies.
