Bird community in an Araucaria forest fragment in relation to changes in the surrounding landscape in Southern Brazil
Provedor de dados: 76
Autores: Scherer-Neto,Pedro; Toledo,Maria Cecília B.
The dynamics of the bird community in a small forest fragment was evaluated along seven years in relation to changes in the surrounding landscape. The study area is an Araucaria forest fragment in Southern Brazil (state of Paraná). The sampling period covered the years 1988 through 1994 and the mark-release-recapture method was utilized. The landscape analysis was based on Landsat TM images, and changes in exotic tree plantations, native forest, open areas (agriculture, pasture, bare soil, and abandoned field), and "capoeira"(native vegetation &lt; 2 m) were quantified. The relationship between landscape changes and changes in abundance diversity of forest birds, open-area birds, forest-edge birds, and bamboo specialists was evaluated. Richness estimates...

Genetic variability of a population of Aedes aegypti from Paraná, Brazil, using the mitochondrial ND4 gene
Provedor de dados: 92
Autores: Twerdochlib,Adriana L.; Bonna,Ana C. Dalla; Leite,Selene S.; Chitolina,Rodrigo F.; Westphal,Betina; Navarro-Silva,Mario A.
Genetic variability of a population of Aedes aegypti from Paraná, Brazil, using the mitochondrial ND4 gene. To analyze the genetic variability of populations of Aedes aegypti, 156 samples were collected from 10 municipalities in the state of Paraná, Brazil. A 311 base pairs (bp) region of the NADH dehydrogenase subunit 4 (ND4) mitochondrial gene was examined. An analysis of this fragment identified eight distinct haplotypes. The mean genetic diversity was high (h = 0.702; p = 0.01556). AMOVA analysis indicated that most of the variation (67%) occurred within populations and the F ST value (0.32996) was highly significant. F ST values were significant in most comparisons among cities. The isolation by distance was not significant (r = -0.1216 and p = 0,...

Autores: Bartozek,Elaine Cristina Rodrigues; Bueno,Norma Catarina; Ludwig,Thelma Alvim Veiga; Tremarin,Priscila Izabel; Nardelli,Margaret Seghetto; Rocha,Angélica Cristina Righetti da.
This study represents a taxonomic survey of class Bacillariophyceae diatoms found in samples collected in the Iguaçu River (Iguaçu National Park, municipality of Foz do Iguaçu, in the state of Paraná, Brazil) between August 2007 and July 2008. Two sampling stations were utilized, the first located upstream of Iguaçu Falls (Cais Bananeiras Station) and second downstream of the falls (Cais Macuco Safari Station). The study resulted in the identification of 86 taxa, including 74 at the specific level and seven taxonomic varieties. Two of these had never before been documented in the state of Paraná: Gomphonema gibberum Hustedt and Pinnularia meridiana Metzeltin &amp;amp; Krammer. Nine are first-time records for Brazil: Cymbella charrua Metzeltin,...

Acanthoceras and Urosolenia species (Diatomeae) in subtropical reservoirs from South Brazil: Ultrastructure, distribution and autoecology
Provedor de dados: 49
Autores: Tremarin,Priscila Izabel; Freire,Eduardo Gomes; Algarte,Vanessa Majewski; Ludwig,Thelma Veiga.
Acanthoceras Honigmann and Urosolenia Round &amp; Crawford emend. Rott, Kling &amp; McGregor species were studied based on samples of 19 hydroelectric power plants reservoirs located in the State of Paraná, Southern Brazil. Autoecological informations of Urosolenia species complement the study. One Acanthoceras and four Urosolenia species were identified: A. zachariasii (Brun) Simonsen, U. amazonica Sala, Núãez-Avellaneda &amp; Vouilloud, U. eriensis var. morsa (West &amp; G.S.West) Bukhtiyarova, U. longiseta Zacharias and U. obesa Freire, Tremarin &amp; Ludwig. Morphological variation of frustules was described and illustrated by optical and scanning electron microscopy, and compared with similar species such as U. delicatissima Sala, Núãez-Avellaneda...

Contribuição ao Estudo da Planície Litorânea do Estado do Paraná
Provedor de dados: 52
Autores: Bigarella,João José.
The present paper contains an approach to systematize the study of the State of Paraná coastal plains, in the southern part of Brazil. It contains in general some geographical and geological data, documented by maps, sketches and photographs. In the initial stage the coastal plain represents a marine ingression, caused by faulting. This ingression penetrated the valleys of a not yet determinated geological landscape. Ended the movement of deeping by faulting begins the epirogenic ascension and building of the barriers and beach ridges. An intensive sedimentation caused the lagoons and bays obstruction. This work refers mainly to t33 he sedimentary formations and the coastal plains is classified in the following way for the study in consideration to the...

Contribuição ao conhecimento da incidência da brucelose no Estado do Paraná (Brasil)
Provedor de dados: 52
Autores: Palmquist,Oscar K.
O rebanho bovino paranaense apresenta um índice de brucelose relativamente alto, particularmente no Norte e Leste do Estado. O gado leiteiro revelou um índice de 7,90%, com um foco grave no Município de Castro (29,92%). Bovinos criados em regime extensivo de pastagens naturais se apresentam com menor grau de infecção, pois a maior incidência foi encontrada no Norte do Estado, onde, regra geral, os campos são constituídos de pastos artificiais.
