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... |

Araucaria Forest is one of most threatened phyto-physiognomies in the Atlantic Forest domain,presenting great ecological-economical importance. Nevertheless, there are still lacks of knowledge concerning growth and dynamic of important species, as Araucaria angustifolia. The objective of this work was to recover the past growth of Araucaria angustifolia, native from Caçador, SC, Brazil, by measuring growth rings and to estimate the average periodic diametric increment. The growth rings were counted and measured, using a stereoscope microscope, in increment cores of 0.5 cm collected from 32 adult trees. The measurements were done with LINTAB measuring table, with 0.01 mm of precision. The samples sizes were irregular, varying from 4.2 to 20.2 cm long. The... |

This study aimed to test the hypothesis that crown length affects the hypsometric relationship. We used data from diameter measured at 1.3 m above ground level (DBH) and total heights of 337 trees of Araucaria angustifolia (Bertol.) O. Kuntze from an urban remnant of Araucaria Forest with 15.24 ha, located in Curitiba, PR, Brazil. These trees were grouped into classes of crown length. Six hypsometric models were adjusted to the data for each class and for the entire data set. The best model was chosen based on the standard error of estimate in percentage, index of Schlaegel, and graphical analysis of residuals. The ranking indicated Trorey as the best model. The models identity test of Graybill applied to the Trorey model indicated that crown length... |

Conhecer o volume de madeira de uma floresta é de extrema relevância. Equações de volume para espécies da Floresta Ombrófila Mista se restringem quase que exclusivamente a araucária. Equações de volume para imbuia Ocotea porosa (Nees & Mart.) Barroso são inexistentes. O presente trabalho tem por objetivo desenvolver equação de volume e relação hipsométrica para árvore individual de Ocotea porosa na região de Rio Negro, PR. Foram derrubadas 12 árvores, com DAP entre 3,98 cm e 43,13 cm e altura entre 5,1 m e 20,4 m. Foi feita cubagem rigorosa de cada uma das árvores. Para desenvolvimento da equação de volume, foram testados onze modelos matemáticos. Os critérios utilizados para a seleção da melhor equação foram o coeficiente de determinação ajustado, o... |

The present study examined the floristic composition of three fragments of Araucaria Forest (AF) in the Planalto Catarinense region of southern Brazil as well as the floristic contextualization of these areas in relation to other remnant AF sites. Three AF fragments at different altitudes were analyzed in the municipalities of Campos Novos, Lages, and Painel. Fifty 200 m² plots were examined in each fragment and all of the trees with CBH (circumference at breast height) > 15.7 cm were identified. In order to floristically contextualize the study fragments, comparisons were made with other remnant AF sites by way of dendrograms and NMDS (Non-metric multidimensional scaling). Environmental and spatial variables were plotted on the diagram produced by the... |

The flower-visiting social wasps (Hymenoptera, Vespidae, Polistinae) in two areas of Rio Grande do Sul State, southern Brazil. The structure of flower-visiting social wasps' assemblages in the CPCN Pró-Mata of São Francisco de Paula and in the Green Belt of Santa Cruz do Sul, Rio Grande do Sul, are characterized. A total of 879 polistine wasps were collected, of which 475 (11 spp.) in the CPCN and 404 (21 spp.) in the Green Belt, from September 1997 to April 2001 and from September 2001 to April 2004, respectively. Foraging social wasps were observed on flowers of 36 species of angiosperms (20 families) in the Green Belt, and on flowers of 54 species of angiosperms (21 families) in the CPCN. Asteraceae was the most visited plant family on both studied... |

Abstract The present paper describes a new species of Actinote (Nymphalidae, Heliconiinae, Acraeini) from southeastern Brazil, and describes the morphology of the adults and immature stages of this species. Actinote mantiqueira sp. nov. occurs in the Serra da Mantiqueira and Serra do Mar in the Atlantic Forest. Adults from this population are very similar to other species of the “orangish red mimicry complex”, including Actinote alalia (C. Felder & R. Felder, 1860), its sister species, restricted to the mountains of southern Brazil. Actinote mantiqueira sp. nov. and A. alalia are distinguishable by wing pattern, male genitalia and larval morphology, and have strongly allopatric distributions. A redescription of Actinote alalia is also provided. |

Due to the incipient state of knowledge of the caddisflies of Brazil, faunistic inventories are extremely important. An inventory of the Trichoptera fauna of Campos do Jordão State Park (CJSP), São Paulo State, based on adults and larvae, is presented here, as well as comments on its taxonomic composition and the implications this poses for the value of conserving the Araucaria Forest. The samples were taken between August 2005 and February 2007. Larvae were collected with a Surber sampler in several kinds of mesohabitats, in 1st to 4th order streams throughout CJSP. Adults were sampled with light and Malaise traps, and also entomological nets. In all, 40 genera of Trichoptera belonging to 15 families were recorded. The CJSP fauna include 60% of the genera... |
