title: Special offer while stocks last: high-energy pulse of nectar caused by a massive post-fire flowering of Sinningia elatior (Gesneriaceae) in an area of Cerrado and implications for its pollination

description: Abstract The massive post-fire flowering of Sinningia elatior (Gesneriaceae) was examined in an area of Cerrado (Brazilian savanna). To study the reproductive system, pollination tests were conducted in the field. Individuals of S. elatior were found isolated or grouped in the area, the orange to reddish flowers are odorless and tubular. Despite being a protandrous species, S. elatior is self-compatible with spontaneous self-pollination, without apomixis. The male phase lasted two days whereas the female lasted three days. The caloric reward per flower was estimated in 40.8 cal ± 4.2 (n = 20). The massive post-fire flowering of this species provided a large, episodic supply of nectar to nine hummingbirds’ species and 16 insects’ species. While all hummingbirds acted as pollinators, insects were only recorded as nectar/pollen thieves. The S. elatior population offered around 23 Kcal, supplying the energetic needs of approximately two to four hummingbirds per day. Post-fire massive flowering is rare and unpredictable in the Cerrado. Therefore, the fire regime acts shaping the flowering dynamics of some species, producing mosaics of temporary special offers of floral resources that affect not only the foraging dynamics of pollinators but also the crossing patterns of the plant species.

title: Angiosperms of dry grasslands and savannahs of Jalapão, the largest conserved Cerrado area in Brazil

description: Abstract This study provides a checklist of angiosperm species from Jalapão region, Tocantins, Brazil, inserted within the Cerrado biome, a global biodiversity hotspot. The region of Jalapão is still well preserved despite current threats to its biodiversity, however its plant diversity is still poorly understood. To generate the present checklist, fieldwork was carried out and relevant herbarium collections were consulted. Angiosperms distributed in the grassland and savanna physiognomies with dry, non-rocky soils were recorded. We detected 550 species within 85 families. The richest families are Leguminosae, Poaceae, Asteraceae, Lamiaceae, Rubiaceae, Myrtaceae, Malpighiaceae and Euphorbiaceae. Among the plant species, ten are listed as rare, ten are threatened, and twelve were identified as new to science. This study increases the number of angiosperm species occurring in these vegetation types in Jalapão almost 2-fold compared to previous inventories. The Cerrado biome and Jalapão region are under heavy threat due to agricultural expansion, and our study contributes to the knowledge of plant biodiversity as a fundamental step towards designing and carrying out conservation actions.

title: Unconventional food plants in the rural (UFP) community of São José da Figueira, Durandé, Minas Gerais, Brazil.

description: Abstract With more than 46.000 species of plants, Brazil has one of the largest biological diversity in the world. This biodiversity is still little known and its use as food has been neglected. The use of local biodiversity in diet contributes to the expansion of the sources of nutrients available to the population and to the promotion of food sovereignty and security. The present study analyzed the knowledge and the use of unconventional food plants (UFP) in the rural community of São José da Figueira, Durandé, Minas Gerais, Brazil. The research was conducted using the Snowball Sampling with semi-structured interviews. The relative frequency of species citation (Fr) was evaluated. There were 56 species of UFP distributed in 29 botanical families. Asteraceae and Lamiaceae were distinguished by the richness of food species, contributing with 9 and 6 species, respectively. Sonchus oleraceus (Asteraceae) and Xanthosoma sagittifolium (Araceae) had the highest relative frequencies of citation (32.1). Most of the plants cited are native (38.2%). The results show the great knowledge of the community about the local diversity, and the importance of these species in the feeding of families. The results show the great knowledge of the community about the local diversity, and the importance of these species in the community alimentation.

title: What are the species of phorophytes of Vanilla palmarum (Orchidaceae) in Brazil? An assessment of emblematic specificity with palm tree species

description: Abstract Vanilla palmarum is an obligately epiphytic orchid distributed widely throughout South America with emblematic specificity for species of palms. This epiphyte-phorophyte association was examined through the analysis of specimens available via the database of Centro de Referência em Informação Ambiental and from Brazilian herbaria. We recognized nine species as hosts of V. palmarum in Brazil: Acrocomia aculeata, Attalea phalerata, Attalea speciosa, Elaeis guineensis, Mauritia flexuosa, Syagrus cearensis, S. coronata, S. schizophylla, and S. vagans. The most important phorophytes of V. palmarum were found to be A. speciosa (Cerrado), A. phalerata (Pantanal), M. flexuosa (Amazon Forest) and S. coronata (Caatinga). Future management actions must consider the association between V. palmarum and its phorophyte palm species in order to ensure the protection of this ecological interaction.

title: Exotic, exotic, exotic: the monotonous urban forestry in a small Brazilian town

description: Abstract Despite the astonishing richness of native biodiversity in Brazil, it is common to see the urban landscapes composed mostly by exotic species, some of which are invasive. This results in little value being given to native plants by urban citizens. In this study we surveyed the urban forestry in the town of Forquilha, in the state of Ceará, Brazil. We aimed to assess how much native plants are being ignored in the composition of the town’s forestry. During a survey of tree and shrub species found in streets and squares of the town, we recorded 1,889 individuals belonging to 44 species. The most common species were the exotic Azadirachta indica (1,184 individuals) and Ficus benjamina (276) both native to Asia. Surprisingly, only three native species were found in our sample, totalling a mere five individuals. It is clear how much the urban forestry of Forquilha is composed predominantly by exotic species. We call here attention to the need for a greater valuation of the native flora in Brazilian cities.

title: Diagnosis of biodiversity knowledge of vascular plants in protected areas of São Paulo state

description: Abstract Based on published data about occurrence of vascular plant species of São Paulo state, we analyzed the role of several protected areas (UCs) in the protection of these species, especially considering endemic or threatened ones. Of 648 ferns and lycophytes in the state, 71% occur in protected areas, 10 are endemics to São Paulo and 30 are threatened. Just under half of the threatened species of ferns and lycophytes were not registered in UCs, and three of these are endemic to the state. For seed plants, of 8,521 species recorded, 48% occur in UCs, 361 are endemics to the state and 676 are threatened. However, 65% of the threatened species are unprotected, and 51 of those are endemic to the state, most of them native to Atlantic Forest. Several UCs still have large lack of knowledge about their flora, of collection effort of botanical material and of record in herbaria, with particular emphasis on Private Natural Heritage Reserves (RPPNs). Our data reinforce the need for expansion of botanical collections in UCs, as well as the creation of new areas in the state, in order to protect threatened and endemic species of São Paulo flora.

title: Analysis of pollen rain in a subandean forest fragment in Colombia

description: Abstract We carried out a modern pollen rain analysis and established its relationship with a Subandean forest fragment in the Cordillera Oriental of Colombia between 1,500 - 2,400 masl RAP transects were performed in order to identify plant species. In each transect, moss samples were collected randomly and processed at the laboratory in order to obtain pollen rain data. Based on pollen grains and vegetation identification and count, we developed pollen diagrams and diversity analysis, and determined the pollen rain and its relation with the vegetation. Cluster and Detrended correspondence analysis (DCA) were performed to determine altitude-associated ecological pollinic species assembly. A total of 66 palynomorphs were identified, being trees the dominant plant habit. The sites located at 2,100 and 2,400 m a.s.l. showed higher pollen diversity. Finally, the Cluster and the DCA show three main groups composed of species that generate a possible dividing line between the low and the high Subandean forest, resulting in new information that can be used for paleoecological interpretation.

title: Flood and fire affect the soil seed bank of riparian forest in the Pantanal wetland

description: Abstract Flood and fire can harm plants but they can have survival strategies, such as the seed bank. We aimed to determine the influence of fire and flood on the richness, abundance and diversity of the seed bank. Sampling was carried out in October/2013, year of prolonged drought, and October/2014, year of a heavy flood, in ten areas along the Paraguay River. The areas were selected in satellite images, five with old burn (2010, three years before sampling) and five with recent burn (2013, three months before sampling). In each area, we marked a 20 m long transect with ten 20 × 20 cm quadrats where we collected 5 cm deep topsoil samples, five with and five without litter. Seed bank richness and abundance were determined by seedling emergence. Old burn areas presented greater abundance than recent burn. The drier year presented greater abundance, richness and diversity than flood year. Removal of litter reduced the richness only in the wetter year. There was no difference in richness in the drier year. The removal of the litter did not affect the abundance and diversity. Interaction between fire and flood did not affect richness, abundance and diversity of the seed bank.

title: Ramet demography of Aechmea distichantha (Bromeliaceae) in two contrasting years in the understory and open areas of a South American xerophytic forest

description: Abstract The Schinopsis balansae forests of the Wet Chaco are characterized by convex areas with woody vegetation and plain areas with herbaceous vegetation. In the Wet Chaco, Aechmea distichantha is a terrestrial bromeliad that forms dense colonies in the understory and open areas of these forests. The aim of this study was to analyze the spatial and temporal variations in population dynamics of this bromeliad species. We monitored ramets growing in sun and shade conditions during two contrasting years. We analyzed the spatial and temporal variations in survival, flowering, and ramet production. Variations in survival, flowering, and ramet production were more marked between years than between habitats. During the year with wetter and milder temperature conditions, survival and ramet production were higher than during the drier year with more extreme temperatures. Survival of vegetative ramets was less variable than survival of young and reproductive ramets. In the colder year, lower winter temperatures reduced the populations in all stages, being more important in the open areas. Our results highlight the importance of low temperatures on A. distichantha demography at this xerophytic forest located at the southernmost distribution range of this bromeliad species.
