1. Xenochlora meridionalis sp. nov. (Hymenoptera: Apidae), a new halictine bee from eastern Brazil as evidence of past connections between Amazonia and Atlantic Forest
ABSTRACT We describe a new species of the bee genus Xenochlora Engel, Brooks & Yanega, 1997, X. meridionalis sp. nov., based on a single female collected in the coastal forests of southeastern Brazil, in the state of Espírito Santo. The disjunct distribution exhibited by Xenochlora, with species in northern South America and in the Atlantic Forest of easter

2. Three new species of Marsdenia (Apocynaceae) from Brazil
ABSTRACT Three new species of Marsdenia (Apocynaceae) are described from Brazil: M. paganuccii, known from two disjunct populations, one in the Caatinga of Bahia and other in the Atlantic Forest of Espírito Santo; M. paraibana, restricted to the Restinga of Cabedelo National Forest in the Atlantic Forest of Paraíba; and M. trisegmentata, known from two pop

3. More on the Mesopotamian-Yungas disjunction in subtropical and temperate Argentina: Bioclimatic distribution models of the harvestman Discocyrtus dilatatus (Opiliones: Gonyleptidae)
ABSTRACT In this paper, the potential distribution of the Mesopotamian harvestman Discocyrtus dilatatus Sørensen, 1884 is modeled, and the species' bioclimatic profile is described. Models were built with the presence-only methods Maxent and Bioclim, using 85 unique records (of which 49 are new) and 11 non-correlated bioclimatic variables as predictors. Bot

4. Análisis de diversidad de la familia Poaceae en la región austral de America del Sur
Abstract Analysis of Poaceae biodiversity in austral South America. The Poaceae is one of the best represented families in austral South America with a total of 206 genera comprising 1523 species arranged in 10 different subfamilies. Here we analyzed the distribution of these taxa in Argentina, southern Brazil (Paraná, Rio Grande do Sul and Santa Catarina),

5. Is the population of Crotalus durissus (Serpentes, Viperidae) expanding in Brazil?
Crotalus durissus are found from Mexico to northern Argentina in a highly disjunct distribution. According to some studies, this species is prone to occupy areas disturbed by human activities and floods comprise a plausible method of dispersal as inferred for some North American rattlesnakes. Based on the literature, it seems plausible that Crotalus durissu

6. Species richness and distribution of bryophytes within different phytophysiognomies in the Chapada Diamantina region of Brazil
The Chapada Diamantina ecoregion is within the caatinga (shrublands) biome of Brazil. Environmental factors determine the phytophysiognomies that distinguish the ecoregion from the surrounding areas. This study aimed to investigate the distribution of bryophyte flora in this ecoregion, by phytophysiognomy and elevational zone. Analyzing specimens we collecte

7. Introduced and native Phlebobranch and Stolidobranch solitary ascidians (Tunicata: Ascidiacea) around Salvador, Bahia, Brazil
The Port of Salvador (12°58'S, 38°30'W) receives cargo ships from different regions such as southeast Asia, North Atlantic, Mediterranean, Africa, North and South America. Thus, the presence of this port enhances the probability of new species arriving and establishing in Todos os Santos Bay (TSB), in which the port is located. Ascidians are sessile filter

8. Revisão taxonômica e análise filogenética de Heteroponerinae (Hymenoptera, Formicidae) / Taxonomy and Phylogeny of the ant Subfamily Heteroponerinae (Hymenoptera, Formicidae)
Heteroponerinae Bolton (2003) compreende três gêneros de formigas: Acanthoponera Mayr, Aulacopone Arnol\ di e Heteroponera Mayr. Acanthoponera é exclusivamente Neotropical, enquanto Heteroponera mostra uma distribuição disjunta nas Américas e Oceania. O gênero Aulacopone, de posição incerta na subfamília, é conhecido por uma única espécie repres

9. Filogenia e biogeografia do complexo Croton pallidulus(Euphorbiaceae), inferidas por sequências de DNA e marcadores AFLP / Phylogeny and biogeography of complex Croton pallidulus (Euphorbiaceae), inferred by DNA sequences and AFLP markers
The project addressed the detection of genetic polymorphisms in a Complex formed by some species of widespread occurrence in southeast of Brazil, whose limits are not yet well established, by presenting great morphological polymorphism that raises doubts as to whether it is a single or various species. The following species were studied: C. ceanothifolius, C

10. Geographic distribution and spatial differentiation in the color pattern of abdominal stripes of the Neotropical stingless bee Melipona quadrifasciata (Hymenoptera: Apidae)
Melipona quadrifasciata Lepeletier, 1836, regionally known as "mandaçaia", has been traditionally divided in two distinct subspecies: M. quadrifasciata anthidioides and M. quadrifasciata quadrifasciata. The main difference between the subspecies refers to the yellow metasomal stripes which are continuous in M. q. quadrifasciata and discontinuous in M. q. an

12. Elevational gradient on the arboreal flora on Moutain Cuscuzeiro, Ubatuba (SP) : a phytogeographic, phytosociologic and floristic analysis / A vegetação arborea em um gradiente altitudinal no Morro Cuscuzeiro, Ubatuba (SP) : uma analise floristica, fitossociologica e fitogeografica
The classification and delimitation of different vegetational formations into a phytogeographic system in Brazil has been a challenge to ecologists, botanists, and phytogeographers. The current distribution of these formations is related to historical process of land use and complex environment gradients, occurring in horizontal (latitude, longitude and edaf
