Genetic structure and conservation of Mountain Lions in the South-Brazilian Atlantic Rain Forest Genet. Mol. Biol.
Castilho,Camila S.; Marins-Sá,Luiz G.; Benedet,Rodrigo C.; Freitas,Thales R.O..
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...

Effects of understory structure on the abundance, richness and diversity of Collembola (Arthropoda) in southern Brazil Neotropical Entomology
Ribeiro-Troian,Vera R; Baldissera,Ronei; Hartz,Sandra M.
The purpose of this study was to investigate the effects of different landscape structures on the understory Collembola community. Four different forest physiognomies were compared: Pinus spp. plantation, Eucalyptus spp. plantation, Araucaria angustifolia plantation, and a remaining native Araucaria forest. Three areas containing two sampling units (25 m x 2 m each) were selected in each forest physiognomy. Understory Collembola collection was done with a 1 x 1m canvas sheet held horizontally below the vegetation, which was beaten with a 1m long stick, seasonally from September 2003 to August 2004. We evaluated the influence of forest physiognomies on the abundance, richness and diversity of Collembola communities. It was also verified if the habitat...

Mattos, Patricia Póvoa de; Santos, Andreia Taborda dos; Rivera, Hugo; Oliveira, Yeda Maria Malheiros de; Rosot, Maria Augusta Doetzer; Garrastazu, Marilice Cordeiro.
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...

Efect of crown length on the hypsometric relationship of Araucaria angustifolia PFB - Pesquisa Florestal Brasileira
Machado, Sebastião do Amaral; Accioly, Yuri; Nascimento, Rodrigo Geroni Mendes; da Silva, Luís César Rodrigues; Cardozo, Claudia Carla.
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...

Quantitative analysis of seed rain under natural and artificial perches in the Araucaria Forest PFB - Pesquisa Florestal Brasileira
Mikich, Sandra Bos; Possette, Rafael Fernando da Silva.
The objective of this study was to compare the efficiency in terms of number of seeds deposited under natural and artificial bird-perches set in degraded areas of Araucaria Forest. Six experimental units were used, each containing seed traps set under natural perches (NP), artificial perches (AP) and under open sky (OS). After 12 months of weekly sampling 26880 zoochoric seeds were collected under AP, 5729 under NP, and only seven under OS. Thus, the presence of perches increases dramatically seed deposition and NP are more or as efficient as AP when the effect of deposition area is taken into account.

Santos, Andreia Taborda dos; Mattos, Patricia Povoa de; Braz, Evaldo Muñoz; Rosot, Nelson Carlos.
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...

Floristic composition and phytogeography of the tree component of Araucaria Forest fragments in southern Brazil Rev. Bras. Bot.
Higuchi,Pedro; Silva,Ana Carolina da; Ferreira,Tiago Sousa; Souza,Sheila Trierveiler de; Gomes,Juliano Pereira; Silva,Karina Montibeller da; Santos,Kristiana Fiorentin do.
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...

A new species of Actinote Hübner (Nymphalidae: Heliconiinae: Acraeini) from southeast Brazil Rev. Bras. entomol.
Freitas,André Victor Lucci; Francini,Ronaldo Bastos; Paluch,Márlon; Barbosa,Eduardo Proença.
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.

Distribution and composition of the lichenized mycota in a landscape mosaic of southern Brazil Acta Botanica
Käffer,Márcia I; Marcelli,Marcelo P; Ganade,Gislene.
Lichenized fungi are epiphytic components of forest areas where anthropogenic activities may cause changes in species composition and spatial distribution. The aim of this work is to evaluate how the lichen community is distributed on native and planted vegetation, and also to investigate possible preferences of the lichen community for specific host trees related to bark pH values. A total of 120 host-trees distributed in 12 remnants of native and planted vegetation were analyzed: native Araucaria forest and Araucaria, pine and eucalyptus plantations. Additional samples of lichenized fungi were collected in all vegetation types and adjacent trails, using a non-systematic sampling protocol. One hundred thirteen taxa of lichenized fungi were recorded, of...

Diversity of medium and large neotropical mammals in an area of mixed rain forest Biological Sciences
Marques, Rosane Vera; Fabián, Marta Elena.
 Medium and large mammals (> 1 kg) were studied using camera traps with active sensors in a Conservation Unit located in an area of Mixed Rain Forest or Araucaria Forest (Atlantic Forest at altitude) in the South of Brazil, as a method for investigating the area’s conservation status and enabling comparison with other types of environments in which these mammals occur in the Neotropical region. From June 2005 to December 2010, a sampling effort of 10,844 trap-days yielded records of 21 species. A minimum sampling effort of 3000 trap-days was necessary to obtain records of all of these species. The species with the greatest frequency of photocaptures was Dasyprocta azarae (agouti), followed by Leopardus pardalis (ocelot), Leopardus guttulus (southern...

Simple does not mean poor: grasslands and forests harbor similar ant species richness and distinct composition in highlands of southern Brazil Biota Neotropica
Klunk,Cristian Luan; Giehl,Eduardo Luís Hettwer; Lopes,Benedito Cortês; Marcineiro,Frederico Rottgers; Rosumek,Félix Baumgarten.
Abstract: Several studies addressed ant communities in the dense Atlantic Forest that runs along the Brazilian coast. However, comparatively little is known about the mixed forests and grasslands that occur in the southern range of the Atlantic Forest domain. In this study we performed the first standardized assessment of ants in the forest-grassland mosaic found in the highlands of the state of Santa Catarina. We aimed to investigate and compare ant richness and composition between mixed forests and grasslands in the main mountain range of south Brazil. Ants were collected in two years with ground pitfalls, tree pitfalls and litter samples. Sixty ant species were recorded, resulting in 22 new records for "Planalto Serrano" region and three for the state...

Inventory of caddisflies (Trichoptera: Insecta) of the Campos do Jordão State Park, São Paulo State, Brazil Biota Neotropica
Spies,Marcia Regina; Froehlich,Claudio Gilberto.
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...
