1. Role of wild birds as carriers of multi-drug resistant Escherichia coli and Escherichia vulneris
Emergence and distribution of multi-drug resistant (MDR) bacteria in environments pose a risk to human and animal health. A total of 82 isolates of Escherichia spp. were recovered from cloacal swabs of migrating and non-migrating wild birds. All bacterial isolates were identified and characterized morphologically and biochemically. 72% and 50% of isolates re

2. Flutuação temporal e a relação da amplitude de maré com as aves aquáticas da Laguna da Ilha Comprida, SP, Brasil / Temporal fluctuation and the relation of tidal amplitude with aquatic birds at laguna da Ilha Comprida, SP, Brazil
O objetivo deste trabalho foi estudar a composição da avifauna aquática, a diversidade, suas abundâncias, a variação mensal e sazonal das populações e entender a relação desses fatores com a variação de maré na Laguna da Ilha Comprida. Ocorreram 6193 indivíduos referentes a 54 espécies, a diversidade de acordo com o Índice de Shannon foi 2,70

3. Deslocamentos e migrações de aves em um fragmento florestal no semiárido de Pernambuco, Brasil.
In the Caatinga the birds make relocations during the rainy periods and nearctic and austral migrations. Few studies correlate the rich abundance of birds with rainfall, principally in the Caatinga. Therefore the objectives of this work were to analyze the rich monthly abundance of birds that carry out movements within the region, correlating this data with

4. Evidence of vertical migration in the Ipanema bat Pygoderma bilabiatum (Chiroptera: Phyllostomidae: Stenodermatinae)
Migration is defined as a seasonal and cyclic population movement observed in all animal classes and studied mainly in vertebrates. A considerable part of the knowledge on migration comes from birds, for which migration is an important aspect of their biology. In the case of bats, females usually migrate larger distances than males in some species. The prese

5. Spring migration characteristics of the House Martin, Delichon urbica (Aves: Hirundinidae) in Croatia: A response to climate change?
Many authors have discussed use of birds (and other organisms) as sensitive biomonitors for climate change. In this paper we investigate the long-term trends in first arrival dates of the long-distance migratory House Martin, Delichon urbica (Linneus, 1758), in north-western Croatia during the 28-year period. The aim of this paper is to identify possible rel

6. Caracterização biológica, molecular, imunológica e estabilidade térmica das estirpes vacinais e de isolados da doença de Newcastle de aves de produção industrial e migratórias no Brasil / Biological, molecular, immunological and thermostability characterization of Newcastle disease vaccine strains and isolateds from migratory and industrially raised birds in Brazil
O vírus da doença de Newcastle (VDN) é o agente causador de uma das mais importantes doenças em aves e representa uma ameaça para a indústria avícola. O VDN é um membro da família Paramyxoviridae, subfamília Paramyxovirinae, gênero Avulavirus. São vírus envelopados, não segmentados dotados de genoma RNA de fita simples sentido negativo, associa

7. Evaluation of genetic damage induced by glyphosate isopropylamine salt using Tradescantia bioassays
Glyphosate is noted for being non-toxic in fishes, birds and mammals (including humans). Nevertheless, the degree of genotoxicity is seriously controversial. In this work, various concentrations of a glyphosate isopropylamine salt were tested using two methods of genotoxicity assaying, viz., the pink mutation assay with Tradescantia (4430) and the comet assa

8. Temporal variations of body mass and plumage in Arenaria interpres (Aves: Scolopacidae) along the Brazilian coast
Every year, Brazil receives large flocks of nearly 40 migratory shorebirds species. The accumulation of body fat and nutrients during the summer is necessary for the long return flights of these birds and is fundamental for feather moulting and the change of their plumage. We present here an examination of the relationship between body mass and plumage chang

9. Canine trypanosomiasis: etiology of infection and implications for public health
Canine trypanosomiasis, caused by protozoans of the genus Trypanosoma, is divided into two primary types: the American form (Chagas disease), due to Trypanosoma cruzi infection, and the African form (sleeping sickness or surra), provoked by Trypanosomaevansi. This disease was originally enzootic and affected only wild animals, including mammals and birds, wh

10. Distribuição espacial e temporal de aves limícolas (Charadriiformes) na Ilha dos Caranguejos, Golfão Maranhense, Brasil / Spatial and temporal distribution of shorebirds (Charadriiformes) in Crab Island,Gulf of Maranhao, Brazil
We studied spatial and seasonal distribution of shorebirds (Charadriiformes) in Island of Caranguejos, Gulf of Maranhão. Censuses were conducted seasonally (considering arrival of migrants in South America, wintering, departure and breeding in North America) from September/2007 to July/2008, in two sectors of Island, North and South. We used the methods of

11. Proteoma e transcriptoma comparativo das glândulas salivares de barbeiros das espécies de Rhodnius brethesi, Rhodnius robustus e Panstrongylus megistus
Chagas disease caused by the protozoan Trypanosoma cruzi is mostly transmitted by the triatomine bug and causes over 17 million infections in Latin America. More than 140 species of triatomines were described. The Rhodnius gender comprises almost half of the triatomines found in the Amazon Basin, as Rhodnius brethesi and Rhodnius robustus, normally these ins

12. Interações entre plantas e beija-flores numa comunidade de Floresta Atlantica Montana em Itatiaia, Rio de Janeiro
Studies of plant-pollinator interactions in vegetation communities can contribute to an understanding of evolutionary and ecological questions. This study sought to relate floristic composition, floral features, resource availability and hummingbird visitation in an ornithophilous assemblage in southeastern Brazil. During two years, data on life form, habita
