title: Can tortoises facilitate the germination of plants with dry fruits? A simulation of the effects of Chelonoidis carbonarius (Testudines: Testudinidae) on the germination of Leucaena leucocephala (Fabaceae)

description: Abstract Ingestion of seeds by vertebrates may influence seed germination and dispersion. However the mechanisms responsible by these effects and the importance of turtles in these interactions are still poorly understood. This study aims to evaluate how Chelonoidis carbonarius influences the germination process of Leucaena leucocephala using an experiment conducted at the Federal University of Ceará, Fortaleza-CE, Brazil, that simulates the passage of the seeds of this plant through the digestive tract of C. carbonarius: stomach acidic condition and seeds sown in feces. We demonstrated that sowing the seeds in feces of Chelonoidis carbonarius has a negative effect on the germination of Leucaena leucocephala, decreasing the germination speed index of the seeds, while the acidic conditions have a neutral one. This study is a first attempt to understand how turtles and tortoises may influence the seed germination, and the implications of these findings in natural environments deserve further investigations.

title: Structural development of the fruits and seeds in three mistletoe species of Phoradendron (Visceae: Santalaceae)

description: Abstract Phoradendron is a New World genus of chlorophyllous hemiparasite plants with the distribution extending from the United States to Argentina, including the West Indies. The names given to the fruits within the Visceae are variable and include a viscous berry or pseudoberry bearing a single seed lacking the testa. Here, it was performed an anatomical study about the development of fruit and seed of three species of Phoradendron. During the fruit development the structure of the mesocarp undergoes intense activity of cell division, and it differentiates onto two new mesocarpic regions: the parenchyma and the viscid layer. In its maturity, the seed is ategmic, presenting the embryo entirely embedded within a chlorophyllous endosperm. The occurrence of chlorophyll in the endosperm may be associated to absence of integuments on the seed, which allows the light to reach the seminal tissues throughout the somewhat transparent pericarp. In addition, the Pomaceous fruit, "viscidio" type is proposed as an alternative classification for Phoradendron fruits.

title: Dynamics of the woody vegetation of two areas of Cerrado sensu stricto located on different substrates

description: Abstract Differences in substrates can provoke distinct responses in the dynamics of a plant community. We compared changes the floristic, structural and dynamic parameters of the woody vegetation between burned sites dominated by cerrado típico (CT) and cerrado rupestre (CR), which is characterized by the presence of rocky outcrops, over time. We set up 10 plots (20 m × 50 m) at each site. All individuals (diameter of ≥ 3 cm at 30 cm height above the ground) were identified in the two censuses (2009 and 2012) and measured (stem diameter), after an accidental fire in 2008. Changes in floristic parameters between the CT and CR were not significant. However, we found significant differences (p &lt; 0.05) in structural and dynamic parameters, such as density (CT = 1,523; CR = 2,171 ind.ha-1), basal area (CT = 8.70; CR = 13.00 m2.ha-1), recruitment rates (CT = 24.35; CR = 15.14% year-1; p = 0.01), gain (CT = 8.58; CR= 3.58% year-1), and the loss rates of basal area (CT = 3.88; CR= 2.45% year-1). These differences emphasize the need for a differential evaluation of these sites for the development of effective conservation strategies.

title: Brazilian plant specimens at the Regnellian herbarium: history and repatriation

description: Abstract This article visits the history of Brazil-Sweden's partnership in botany and the contribution of Anders Fredrik Regnell and other botanical collectors to the knowledge of Brazilian flora. The importance of the herbarium of Stockholm (S) is widely recognized for its collections of Brazilian plants, one of the largest in the world. The majority of the collections from Brazil date from the period between the second half of nineteenth century and the beginning of the twentieth century. The main collectors of Brazilian flora from that phase, whose bulk of collections are in Stockholm are Anders Regnell, Gustaf Malme, Per Dusén, Carl Lindman and many others sponsored by the Regnellian fund. The herbarium also houses substantial collections of August Glaziou, a great contributor to the knowledge of the flora of state of Goiás, and Adolf Ducke, pioneer in the taxonomy of Amazonian tree species. The cooperation between Brazil and Sweden is currently being renewed through Rio de Janeiro Botanical Garden and the Reflora Program, allowing repatriation of Brazilian specimens housed in Stockholm.

title: Piptadenia (Leguminosae, Mimosoideae) in the state of Minas Gerais, Brazil

description: Abstract The genus Piptadenia includes approximately 24 species that are distributed in the tropical regions of South America, with centers of diversity in the Amazon and Atlantic Forest in Brazil in which twenty-one species occur. A taxonomic study of Piptadenia was conducted in the state of Minas Gerais based on an analysis of approximately 270 specimens from 11 herbaria, field observations and field work in the main conservation units and other focal areas in Minas Gerais. These areas include the three vegetation domains in the state: Atlantic Forest, Cerrado and Caatinga. Six of the species in the genus were sampled: P. adiantoides, P. gonoacantha, P. macradenia, P. micracantha, P. paniculata and P. viridiflora. Two species that have previously been cited in the state were not found in this study: P. irwinii and P. stipulacea. These species were not found in the herbaria collections that were consulted or during the field work. We present an identification key for the Minas Gerais species of Piptadenia as well as descriptions, illustrations, geographical distributions, comments about the taxonomic characters and some information related to the flowering and fruiting periods.

title: Vascular epiphytes in the Grumari restinga, RJ: floristic and similarities between restingas in Eastern Brazil

description: Abstract The community of vascular epiphytes in the Grumari restinga, Rio de Janeiro state, was evaluated through surveys carried out in 2014 and supplemented with herbarium material and publications. Thirty-seven (37) vascular epiphyte species were recorded, distributed in 21 genera and six families. The richest families are Orchidaceae and Bromeliaceae, which are the most representative ones (67.6% of all record species). The richness in Grumari restinga is greater than the other inventories carried out in the coastal plain of the Southeastern Region of Brazil, however, lower than that of restingas for São Paulo, Paraná and of the coastal plain of Rio Grande do Sul. The most representative ecological category was the characteristic holoepiphyte (62%); it was followed by the facultative and accidental holoepiphytes (18% each). The Grumari restinga shares more species with Espírito Santo state and Rio de Janeiro than with São Paulo and Southern Region of Brazil, possibly due to the geographical distance. Our study provides the first contribution to the knowledge about the epiphytic flora in Grumari restinga and shows a singular flora with 40% of unique species occurring in this location, fact that justifies its importance as conservation area.
