1. Morphological differentiation between seven Brazilian populations of Haemagogus capricornii and Hg. janthinomys (Diptera: Culicidae) using geometric morphometry of the wings
Abstract INTRODUCTION: Haemagogus capricornii and Hg. janthinomys females are considered morphologically indistinguishable. We analyzed morphometric variability between Brazilian populations of these species using wing geometric morphometry. METHODS: Size and shape at intra- and interspecific levels were analyzed in 108 Hg. capricornii and Hg. janthinomys

2. Identification of nurseries areas of juvenile Prochilodus lineatus (Valenciennes, 1836) (Characiformes: Prochilodontidae) by scale and otolith morphometry and microchemistry
ABSTRACT The streaked prochilod Prochilodus lineatus (Valenciennes) is a commercially freshwater species from South America, distributed in the Plata basin. In the present work the morphometry (circularity, rectangularity, form factor, OL/OW and ellipticity indices) and chemistry (Sr:Ca, Ba:Ca, Zn:Ca) of lapilli otolith, and geometric morphometry of scales o

3. Where do these bugs come from? Phenotypic structure of Triatoma infestans populations after control interventions in the Argentine Chaco
House re-invasion by native triatomines after insecticide-based control campaigns represents a major threat for Chagas disease vector control. We conducted a longitudinal intervention study in a rural section (Area III, 407 houses) of Pampa del Indio, northeastern Argentina, and used wing geometric morphometry to compare pre-spray and post-spray (re-infestan

4. Potential sources of Triatoma infestans reinfesting peridomiciles identified by morphological characterization in Los Llanos, La Rioja, Argentina
The presence of Triatoma infestans in habitats treated with insecticides constitutes a frequent problem in endemic areas. Basing our study on the hypothesis that descendants of a residual population should be more similar to the pre-treatment population than to any other, we compared the indications of two quantitative morphological approaches. This study se

5. AVALIAÇÃO MORFOMÉTRICA E MOLECULAR DE ABELHAS MANDAÇAIAS (MELIPONA SPP.) DA REGIÃO DA FOZ DO RIO SÃO FRANCISCO. / MORPHOMETRIC MOLECULAR AND EVALUATION OF BEES MANDAÇAIAS (MELIPONA SPP.) REGION OF THE MOUTH OF THE RIVER SÃO FRANCISCO.
No gênero Melipona, a abelha Melipona quadrifasciata é uma das espécies mais conhecida e está dividida em duas subespécies M. q. quadrifasciata e M. q. anthidioides. O presente trabalho teve como objetivo avaliar a identidade das abelhas mandaçaia do litoral norte do Estado de Sergipe por meio de técnicas moleculares e morfométrica, e verificar a pos

6. Diversificação evolutiva de gobídeos no litoral brasileiro: padrões citogenéticos e ecomorfológicos
The fishes of the order Perciformes are characterized as an important model for understanding the genetic structure of marine populations, because besides they present examples of conservation chromosomal, also they present the karyotype diversification for some groups. Gobiidae family is the most specious in the marine environment. Among its representatives

7. A morphometric and molecular study of Anastrepha pickeli Lima (Diptera: Tephritidae)
This study investigated the level of morphometric and genetic variability among populations of Anastrepha pickeli Lima from several localities in Brazil, one locality in Bolivia and one in Paraguay. Traditional and geometric morphometric analyses were used, as well as sequencing of a fragment of the cytochrome oxidase gene (COI). Six variables were measured

8. Analysis of the genetic variability of a small population of Frieseomelitta varia (Hymenoptera, Apidae, Meliponini) through mitochondrial DNA analysis, microsatellites and geometric morphometry of wings / Análise da variabilidade genética de uma pequena população de Frieseomelitta varia (Hymenoptera, Apidae, Meliponini) por meio de análise do DNA mitocondrial, microssatélites e morfometria geométrica das asas
As abelhas da tribo Meliponini apresentam distribuição pantropical. São encontradas mais de 400 espécies pertencentes a 50 gêneros, sendo que mais de 300 estão presentes nas Américas. Os meliponíneos são responsáveis por grande parte da polinização das plantas nativas. A destruição das florestas tem ameaçado seriamente as abelhas sem ferrão,

9. Análises morfométricas e moleculares de espécies de Doryctobracon Enderlein e Opius Wesmael (Hymenoptera: Braconidae), parasitóides de moscas-das-frutas (Diptera: Tephritidae) / Morphometric and molecular analysis of species of Doryctobracon Enderlein and Opius Wesmael (Hymenoptera: Braconidae), parasitoids of fruit flies (Diptera: Tephritidae)
This study aimed to elucidate the identity of two-closely related species of Doryctobracon areolatus (Szépligeti) and a closely related species of Opius bellus Gahan, commonly referred to as Opius sp. aff. bellus, by using geometric morphometry and molecular analysis (ITS2 rDNA and 28S rDNA D2 regions). The analysis based on 20 landmarks through the multiva

10. Use of multivariate techniques and geometric morphometry in the discrimination of rhinobatos species (Family Rhinobatidae) of the Northeast from the Brazil / Utilização de técnicas multivariadas e de morfometria geométrica na discriminação de espécies do gênero Rhinobatos (Família Rhinobatidae) do Nordeste do Brasil
The guitarfish Rhinobatos cf percelens is a marine ray inhabiting shallow coastal waters in southern hemisphere. The analyzed sample was collected at Caiçara do Norte, off Rio Grande do Norte state (Brazil). Traditional techniques and geometric morphometry were used aiming at identifying the specific status of the exploited species along the Brazilian North

11. Caracterização morfológica e molecular de híbridos do cruzamento entre Triatoma maculata (Erichson, 1848) e Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae). / Morphologic and molecular characterization of hybrids from the cross breeding among Triatoma maculata (Erichson, 1848) and Triatoma pseudomaculata Corrêa &Espínola, 1964 (Hemiptera: Reduviidae)
Due to its great morphological similarities, Triatoma maculata and Triatoma pseudomaculata, classified by Carcavallo et al. (2002) in the maculata complex, were considered the same species until 1964 (Corrêa e Espínola, 1964). These species are alopatric and, according to Schofield (1988), T. maculata would be introduced in the brazilian Northeastern by mi
