| The Monimiaceae is represented in the Neotropical region by six genera. Macropeplus Perkins is a Brazilian genus comprising four species restricted to high-montane Atlantic Forest areas, which have not been properly examined from the anatomical point of view. This study characterizes the anatomical structure and histochemical aspects of the leaves of Macropeplus dentatus and M. ligustrinus, and adds to our taxonomic knowledge ofthe genus. The individuals studied were collected in the Serra dos Órgãos National Park and in the Caraça Natural Park in southeastern Brazil. Among the characteristics common to the two species, hypostomatic leaves, dorsiventral structure, paracytic stomata, a subepidermal layer, collateral vascular system in the form of an arc in... |

| The upper montane forests in the southern and southeastern regions of Brazil have an unusual and discontinuous geographic distribution at the top of the Atlantic coastal mountain ranges. To describe the floristic composition and structure of the Atlantic Forest near its upper altitudinal limit in southeastern Brazil, 30 plots with 10 × 10 m were installed in three forest sites between 2,200 and 2,300 m.a.s.l. at Serra Fina. The floristic composition and phytosociological structure of this forest were compared with other montane and upper montane forests. In total, 704 individuals were included, belonging to 24 species, 15 families, and 19 genera. Myrsinaceae, Myrtaceae, Symplocaceae, and Cunoniaceae were the most important families, and Myrsine... |

| The resilience, ecological function and quality of both agricultural and natural systems were evaluated in the mountainous region of the Atlantic Rain Forest of Rio de Janeiro through Rapid Assessment Methods. For this goal new indicators were proposed, such as eco-volume, eco-height, bio-volume, volume efficiency, and resilience index. The following agricultural and natural systems have been compared according: (i) vegetables (leaf, fruit and mixed); (ii) citrus; (iii) ecological system; (iv) cattle, (v) silvo-pastoral system, (vi) forest fragment and (vii) forest in regeneration stage (1, 2 and 3 years old). An alternative measure (index) of resilience was proposed by considering the actual bio-volume as a function of the potential eco-volume. The... |

| Abstract Seed dispersal is a process that is fundamental to maintenance of forest ecosystems, enabling plants to successfully germinate in sites that are favorable to their growth, minimizing risks of competition, the action of pathogens and predation by herbivores. Intraspecific and seasonal variations in fruit consumption by Didelphis albiventris, and its contribution to dispersal and germination of endozoochorous seeds were analyzed in a Semideciduous seasonal forest. The study was conducted at Morro do Coco, which is a hilly area in the municipal district of Viamão, RS, Brazil, bordering the shore of Guaíba lake (30º16’15”S, 51º02’54”W), between June 2013 and May 2014, with a total sampling effort of 2992 trap-nights. A total of 18 individuals were... |

| The lizard, Cercosaura ocellata, with its type-locality suggested as being South America's Northeast, is widely distributed in the North and Midwest regions of Brazil, with scarcity of records for the states in the Northeast Region. This work aims to enlarge the geographical distribution of this species. An individual of C. ocellata was registered in a fragment of Atlantic Rain Forest, Mata de Tejipió (08° 05′ 45.59″ S, 34° 57′ 04.91″ W). This register expands its distribution 585 km north and 770 km south, respectively from its closest locations, Bahia and Ceará, filling a gap of disjunct distribution of approximately 900 km in the northeast region of the country. |

| We conducted experiments by blocking off pit-like domatia from old and new leaves of Coffea arabica L., using tiny resin drops, to investigate the role of domatia on i) mite abundance at the community level and on ii) leaf damages. More than 77% of the mites collected were predators, whereas 19 and 3.3% were omnivores and phytophages, respectively. Domatia blockage treatment had no influence either on mite abundances or leaf damages. However, predatory and omnivorous mites were more abundant on new than on the old leaves; phytophagous mites occurred at very low density and occupied only plants having open domatia. The absence of mutualism between mites and C. arabica probably occurred because the entrances of domatia were too small and did not enable the... |

| Abstract This work contributes to the knowledge of the fern and lycophytes diversity in the Picinguaba and Santa Virginia Nuclei, Parque Estadual da Serra do Mar (PESM), Ubatuba, São Paulo, Brazil, as well as to provide subsidies to identification of the found taxa in these areas. In total, 30 collecting expeditions were conducted and the vouchers were deposited at UEC Herbarium. We have identified 135 species distributed in 53 genera and 19 families for both areas. The most representative families were Polypodiaceae (28 species) and Dryopteridaceae (19 species), whereas Asplenium (12 species), Blechnum and Elaphoglossum (8 species each) were the most important genera. Epiphytic species predominated (62 overall), probably due to the presence of favorable... |

| The acrocerids (small headed-flies) form a small group of flies, which are difficult to find and observe. They are rare in collections. Their larvae are heteromorphic parasitoids of many families of spiders and their imagoes show a great deal of morphological variation. Little is known about the biology and systematics of this group in the Neotropical region, especially the Philopotinae. Most studies are based on species from Europe and North America. The Philopotinae occurs througout the world, and are characterized by the strongly developed postpronota, which form a shield dorsally in front of the scutum. Fifty specimens of Philopota sp. were collected from branches of Stachytarphetta cayenensis (Verbenaceae) in the Ilha da Marambaia (23º 04' S - 43º 53'... |

| The Brazilian Atlantic Rain Forest, one of the most endangered ecosystems worldwide, is also among the most important hotspots as regards biodiversity. Through intensive logging, the initial area has been reduced to around 12% of its original size. In this study we investigated the genetic variability and structure of the mountain lion, Puma concolor. Using 18 microsatellite loci we analyzed evidence of allele dropout, null alleles and stuttering, calculated the number of allele/locus, PIC, observed and expected heterozygosity, linkage disequilibrium, Hardy-Weinberg equilibrium, F IS, effective population size and genetic structure (MICROCHECKER, CERVUS, GENEPOP, FSTAT, ARLEQUIN, ONESAMP, LDNe, PCAGEN, GENECLASS software),we also determine whether there... |

| The environment most diverse in harvestmen species is the Atlantic Forest of São Paulo. However, there remains a lack of studies regarding their communities in certain regions. Among these regions is one south of the Paranapiacaba mountain range in the state of São Paulo, the Parque da Onça Parda (POP). Through nocturnal collections and pitfall traps, the region's harvestmen community has been studied. The observed richness of this site included 27 species, with dominance of three species: Holcobunus nigripalpis Roewer, 1910, Neosadocus maximus (Giltay, 1928) and Munequita sp., accounting for 68.4% of harvestmen abundance. This makes the diversity of POP more similar to the semideciduous Atlantic Forest communities of the interior than to those of the... |

| The tadpole of Hypsiboas atlanticus (Caramaschi & Velosa, 1996) is described from the municipality of Maceió, State of Alagoas, Brazil. At stage 36 the larvae have an overall elliptical body in lateral and dorsal views, oral disc anteroventral, spiracular tube sinistral, and labial tooth row formula 2(1,2)/3(1). The oral disc is surrounded, almost completely (anterior medial gap present) by a single row of marginal papillae. Described tadpoles of the H. punctatus species group can be differentiated by a combined disc oral features. Additional descriptions of H. punctatus (Schneider, 1799) tadpoles from populations throughout South America may be helpful in determining the status of these populations. |

| The definition of areas of endemism is central to studies of historical biogeography, and their interrelationships are fundamental questions. Consistent hypotheses for the evolution of Pentatomidae in the Neotropical region depend on the accuracy of the units employed in the analyses, which in the case of studies of historical biogeography, may be areas of endemism. In this study, the distribution patterns of 222 species, belonging to 14 Pentatomidae (Hemiptera) genera, predominantly neotropical, were studied with the Analysis of Endemicity (NDM) to identify possible areas of endemism and to correlate them to previously delimited areas. The search by areas of endemism was carried out using grid-cell units of 2.5° and 5° latitude-longitude. The analysis... |

| In the present work, we determined the relative importance of allochthonous and autochthonous food items as well as seasonal and ontogenetic variation in the feeding habits of Phalloceros anisophallos from córrego Andorinha, Ilha Grande. Quantitative analysis, based on alimentary index (IAi) and food volume (Vo), revealed that P. anisophallos fed on detritus, autochthonous algae (diatoms, unicellular and filamentous Chlorophyceae algae), autochthonous animals (aquatic insect larvae: Trichoptera, Chironomidae and other Diptera) and allochthonous animals (terrestrial insects: Hymenoptera). Ontogenetic variations were recorded for the consumption of each food category. Adults used a larger amount of algae and detritus, and juveniles used a higher amount of... |
