Item Acesso aberto (Open Access) Filogenia da tribo Attacobiini Roewer, 1955 (Araneae, Corinnidae, Corinninae)(Universidade Federal do Pará, 2015-04-02) PEREIRA FILHO, José Moisés Batista; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503A cladistic analysis of tribe Attacobiini (Corinnidae, Corinninae) with 17 taxa and 109 characters is presented. The outgroup is composed by four species (Castianeira aff rubicunda ACR; Xeropigo cotijuba; Septentrinna yucatan and Falconina gracilis) all of them represented by males and females. The ingroup is represented by 13 Attacobiini species, seven of which represented by both sexes (Attacobius TOC; A. attarum; A. verhaaghi; A. lamellatus; A. uiriri; A. blakei and A. carranca), three represented only by females (A. luederwaldti; A. nigripes and A. kitae) and three represented only by males (Ecitocobius comissator; Attacobius PAR and A. tucurui). Regarding to terminals, the present data matrix represent an increase of two species in relation to a previous analysis of the Tribe. The availability of data was improved by adding character states on genitalic features for three terminals, of which the counterpart sex was unknown at the time in which that previous analysis was made (males of A. verhaagui and females of A. blakei and A. uiriri). Furthermore, several characters used in the previous analysis were re-interpreted and some new characters were proposed. A single tree was obtained under equal weights. Attacobinni and Attacobius were retrieved as monophyletic groups but the groups of species of Attacobius depicted here are considerably different from those recognized in the previous analysis. The exact solution under equal weights and all characters running unordered resulted in a fully resolved, single most parsimonious tree. As in the previous analysis, the bettersupported clades were Attacobiini and Attacobius. However, the groups of Attacobius species recovered here are considerably different from the ones recovered previously, with the exception of an apical clade composed by A. nigripes, A. kitae, A. attarum and A. luederwaldti, which was recognized in both analyses as the best supported group within the genus.Item Acesso aberto (Open Access) Inventário da araneofauna (Arachnida, Araneae) de serapilheria na Estação Científica Ferreira Penna, Pará, Brasil(Universidade Federal do Pará, 2004-03-02) BARREIROS, José Augusto Pereira; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503The Ferreira Penna Scientific Station (ECFP), with near 33.000 ha, is located at Caxiuanã National Forest, Pará state, Brazil. A structured protocol of ground litter spiders sampling resulted in 400 samples of 1m² concentrated litter, from both rainy and dry seasons. The spiders were sorted by a combination of manual sorting and Winkler device techniques. These samples were obtained in five plots, three located in Terra Firme (dryland) forest (LBA-EXP, LBA-CON and TF-IMC) and two in igapó (wetland) forest (IG-N and IG-S). One of the Terra Firme plots (LBA-EXP) is under hidric stress and it was used plastic panels and gutters to exclude most of the rainfall. A total of 2230 individuals (mean: 5,6 individuals / m²), beionging to 34 families, were collected. Seven families were represented only by juveniles: Nesticidae, Pisauridae, Gnaphosidae, Mimetidae, Deinopidae, Oxiopidae, Uloboridae. The most abundant families were Salticidae, Theridiidae, Ctenidae, Oonopidae and Linyphiidae. 876 adults, beionging to 120 species or morphospecies in 27 families were sampled. The most abundant species were Styposis sp.3 (Theridiidae), with 16,55% of all adults, Anapisona sp.1 (Anapidae), with 6,96%, Meioneta sp.1 (Linyphiidae), with 6,39%, Oonopidae sp.1, with 5,59% and Salticidae sp.1, with 4,56%. In order to implement the majority of the analysis, 15 occasional species were excluded. The observed species accumulation curves for all samples and for the samples from each plot didn't reach the asymptote in the end of samples addition. The patterns of abundance and incidence of these species suggest the existence of total species richness from 123 to 184 species. The largest species richness estimates were from plot LBA-EXP (75 - 110 species). The smallest ones were observed at plot IG-N (25 - 59 species). Despite the species richness and the abundance of spiders had reached the largest values at plot LBA-EXP, the overall diversity was larger at plots LBA-CON and TF-IMC. The Igapó overall diversity was lower than in Terra Firme. The species composition was different in Terra Firme and Igapó habitats, as demonstrated by similarity indexes and percentage complementarity. The abundance and species richness of litter spiders increased in dry period and decreased with the raising of soil residual humidity.Item Acesso aberto (Open Access) Inventário da araneofauna (Arachnida, Araneae) do Parque Nacional de Sete Cidades, Piauí, Brasil(Universidade Federal do Pará, 2008-03-25) CARVALHO, Leonardo Sousa; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503An inventory of the spider fauna of Sete Cidades National Park (Brasileira and Piracurua municipalities, State of Piauí), is presented using standardized sampling procedures to allow comparisons between the spider assemblages of six phytophysiognomies present at the study site and to obtain richness estimates. Data from sampling with pit-fall traps (PTF), Winkler apparatus (WIN), beating tray (GCE), sweeping net (RV) and nocturnal manual colleting (MN), totalizing 1386 samples were analyzed, together with all other specimens previously collected at the study site (n=1166). The statistical analyses were performed using data obtained with GCE, RV and MN. Altogether, 14.890 individuals (4491 adults), belonging to 364 species, were collected. From these, 72 were determined at specific level, 62 are new records for the study site, 2 are new records for Brazil and 48 were recognized as new species by specialists. The application of the methods GCE, RV and MN resulted in 11.085 spiders, belonging to 303 species. The richness estimates varied between 355 (Boostrap) and 467 (Jack 2) species. The best fit estimator, which first showed a trend to reach an asymptote, was Chao 2 (403 spp.). The observed richness was greater in tropical semideciduous dry forest (mata seca semi-decídua, 131 spp.), followed by the tropical ombrophilous alluvial occasionally flooded forest (mata de galleria, 104 spp.), medium tall grassland consisting mainly of bunch grasses (campo limpo, 102 spp.), evergreen broad-leaved woodland (cerradão, 91 spp.), evergreen broad-leaved sclerophyllous shrubland (cerrado típico, 88 spp.) and smaller in deciduous subdesert shrubland (cerrado rupestre). The efficiency of the collecting methods exhibited variation according to the phytophysiognomy in which it was applied, especially in the case of the sweeping net, which was much more efficient in open areas. The variation in species composition between the sampled phytophysiognomies can be, in part, explained by differences in the structural complexity of these vegetation types. The results of the cluster analysis suggest that, in conditions of high dominance, these tests should be performed with qualitative coefficients, in order to neutralize the effect of coefficient choose and/or the need of data transformation. The Sete Cidades National Park´s spider fauna does not followed the clustering patterns suggested by botanical analysis, by which grasslands, savannas and forested phytophysiognomies are grouped.Item Acesso aberto (Open Access) Inventário de aranhas (Arachnida, Araneae) em quatro fitofisionomias da serra do cachimbo, Novo Progresso, Pará, Brasil(Universidade Federal do Pará, 2005-03-04) RICETTI, Janael; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503A inventory of the spider fauna was carried out at Serra do Cachimbo, inside the "Campo de Provas Brigadeiro Velloso", Novo Progresso municipality, Pará state, Brasil. Two expeditions were made, during both dry (August and September, 2003) and wet (March and April, 2004) seasons. Three collectors participated in each expedition. The sampling effort, represented by 240 samples, was divided through the following methods: beating tray and sweeping net (96 samples); nocturnal hand search (96 samples) and concentrated litter sorted by a combination of hand search and Winkler extractors (48 samples). The spiders assemblages from four vegetation types (open rainforest, Formiga river's riparian forest, arboreal savanna and white sand vegetation) were compared. A total of 4964 spiders were obtained, from which 2724 adults, resulting in 397 recognized morpho-species in 37 families. The most abundant families were Theridiidae, Salticidae and Araneidae and the ones with more species were Salticidae, Araneidae e Theridiidae. The singletons represented 40% of the total species richness and only two species presented more than 100 individuals. The estimated richness species curves reached from 473 (bootstrap) to 674 (jackknife2) species. The higher alpha-diversity (Shannon-Wiener index) was observed in open rainforest, followed by Formiga river's riparian forest, white sand vegetation and arboreal savanna. the higher beta-diversity (Jaccard and Morisita-Horn indexes) was observed between Open rainforest and white sand vegetation and the lowest one was between open rainforest, arboreal savanna and Formiga river's riparian forest. The dry season presented more species than the wet season. However, no such difference was detected in white sand vegetation. A principal component analysis revealed that some species are linked to arboreal vegetations and others are linked to the open vegetation in white sand. Those differences in diversity and taxonomic composition between the various vegetations can be explained by drifts in availability of food items (preys), space resources (refugees and substratum to web attachment), as well as micro-climatic factors (temperature and moisture) of a given vegetation type. The most experienced conectar sampled more species than any other collector and all less experienced collectors sampled similar number of species. The differences in abundance among samples obtained by each conectar were not significant. The night hand sampling was the most efficient technique regarding the detection of differences in species richness among vegetation types. The methods beating tray/sweep net and litter sampling do not showed any significant difference in relation to species richness.Item Acesso aberto (Open Access) Novas espécies do gênero Neoxyphinus birabén 1953 (Araneae: Oonopidae) do Brasil(Universidade Federal do Pará, 2016-02-28) FEITOSA, Níthomas Mateus das Neves; RUIZ, Gustavo Rodrigo Sanches; http://lattes.cnpq.br/3135887179267009; BONALDO, Alexandre Bragio; http://lattes.cnpq.br/8721994758453503Twenty-seven new species of the genus Neoxyphinus are described, all from Brazil, are described, rising the total number of species of the genus to 48.

From Schmalfuss (1989), monophytic Oniscidea was accepted, based on derivated characters common to all Oniscidea. Dubioniscidae was erected by Schultz to include the genera Dubioniscus Vandel, 1963, Calycuoniscus Collinge, 1915 and Phalloniscus Budde-Lund, 1908 and the genus Novamundoniscus Schultz, 1995, erected to allocate the american species of Phalloniscus. This study aimed to make the taxonomic review of Novamundoniscus and to produce phylogenetic hipotesis of monophyletic relations of the species that compound this genus, based on morphology, to elaborate a phylogenetic relationship hipotesis among the genera that compounds Dubioniscidae, redescribe known species and describe new ones. This work is presented in a single chapter, divided into two parts, taxonomy and phylogeny of Novamundoniscus. 18 species of Dubioniscus, Novamundoniscus e Phalloniscus were analysed and a data matrix with 73 characters was generated. The final tree revealed Dubioniscidae as monophiletic, but, the validity of the genus Novamundoniscus could not be confirmed. The results of the phylogenetic analyses presented herein are considered provisory and, the taxonomic implications of the topology discussed were not adopted in the taxonomic revision of Novamundoniscus. However, the optimizations of the characters in this topology furnishes important conclusions for the understanding of the evolutive history of the taxa analysed and the characters matrix offers a solid basis for the continuation of this line of research.Item Acesso aberto (Open Access) Sobre o gênero Tenedos O.
