1. Chromosomal polymorphism and comparative chromosome painting in the rufous-collared sparrow (Zonotrichia capensis)
Abstract Zonotrichia capensis is widely distributed in the Neotropics. Previous cytogenetic studies demonstrated the presence of polymorphisms in two chromosome pairs (ZCA2 and ZCA4). Here, we report results based on comparative chromosome painting, using probes derived from Gallus gallus and Leucopternis albicollis, focused on characterizing the chromosome

2. Frequency of zoonotic bacteria among illegally traded wild birds in Rio de Janeiro
Abstract The illegal wildlife trade may increase the risk of infectious disease transmission, and it may not only cause disease outbreaks in humans but also threaten livestock, native wild populations, and ecosystems' health. Bird species may act as carriers in the transmission of enteric pathogens. However, epidemiological studies on zoonotic bacteria in wi

3. Extra-pair paternity in a Neotropical rainforest songbird, the White-necked Thrush Turdus albicollis (Aves: Turdidae)
ABSTRACT Over the last two decades, several studies have shown that the mating systems of various birds are more complex than previously believed, and paternity tests performed with molecular techniques have proved, for instance, that the commonly observed social monogamy often presents important variations, such as extra-pair paternity. However, data are st

4. NOTES ON TAXONOMY AND DISTRIBUTION OF MYRSIDEA SERINI (SÉGUY, 1944) (PHTHIRAPTERA: AMBLYCERA: MENOPONIDAE) ON SOUTHERN SOUTH AMERICAN PASSERINE BIRDS (AVES: PASSERIFORMES)
Myrsidea serini (Séguy, 1944) é registrada de três passarinhos distintos como hospedeiros na Argentina e Chile: Carduelis barbata (Molina, 1782) (Fringillidae), Chrysomus thilius petersi (Laubmann, 1934) e Agelaioides badius badius (Vieillot, 1819) (Icteridae). Características somáticas e medidas corporais de exemplares disponíveis dessas populações

5. Adição de polieletrólito ao processo de floculação no pós-tratamento de lixiviado por coagulação-floculação-sedimentação
A adição de polieletrólito ao processo de floculação no tratamento físico-químico por coagulação-floculação-sedimentação de efluentes tem sido uma alternativa para a obtenção de clarificados de boa qualidade em menor tempo devido ao aumento da velocidade de sedimentação. Deste modo, este artigo, objetivou determinar as inter-relações entre

6. Isospora bocamontensis (Pereira et al., 2011) (Protozoa: Apicomplexa) EM CARDEAIS-AMARELO Gubernatrix cristata (Vieillot) (Passeriformes: Emberezidae) / Isospora bocamontensis (Pereira et al., 2011) (Protozoa: Apicomplexa) IN YELLOW CARDINAL Gubernatrix cristata (Vieillot) (Passeriformes: Emberezidae)
O cardeal-amarelo (Gubernatrix cristata) é um pássaro que ocorre no sul do Brasil, principalmente na fronteira com Uruguai e Argentina. É uma ave ameaçada de extinção e sua população está decrescendo devido a perda e fragmentação do seu habitat além da captura ilegal. No Brasil sua criação em cativeiro é regulamentada pelo órgão governamenta

7. História natural da erva-de-passarinho Psittacanthus robustus (Loranthaceae) em uma área de campo rupestre do sudeste brasileiro : interações com hospedeiras, dispersores, polinizadores e insetos herbívoros / Natural history of the mistletoe Psittacanthus robustus (Loranthaceae) at a rupestrian filed site in southeastern Brazil : interactions with hosts, seed dispersers, pollinators and insect herbivores
In this study I investigated some aspects of the natural history of the woody mistletoe Psittacanthus robustus Mart. (Loranthaceae) in rocky outcrops in the Serra do Cipó, southeastern Brazil. This species was recorded parasitizing eight host species in Five families, although trees within Vochysiaceae comprise the main hosts. Pattern of distribution was cl

8. Biologia reprodutiva e comportamento cooperativo em ninhos de Cyspsnagra Hirundinacea
White-rumped Tanager (Cypsnagra hirundinacea) is a cooperative breeding species, which helpers are offspring of earlier breeding seasons. This species occurs in open areas of the Cerrado (Neotropical savanna). The first chapter of this dissertation presents a description of several aspects of C. hirundinacea reproductive biology, including reproductive perio

9. Estruturação genética em populações do tangará-dançarino Chiroxiphia caudata (Aves, Pipridae) no corredor costeiro da Mata Atlântica (SP) e sua importância para a conservação.
Neotropical passerine birds that inhabit forests understory are thought to be highly sedentary, which may result in greater genetic differentiation among populations than in temperate species. The species of the genus Chiroxiphia (Pipridae) perform highly specialized courtship displays in which males aggregate at traditional arenas, or ``leks, performing a p

10. Phylogeny and diversification of the largest avian radiation
The order Passeriformes (“perching birds”) comprises extant species diversity comparable to that of living mammals. For over a decade, a single phylogenetic hypothesis based on DNA–DNA hybridization has provided the primary framework for numerous comparative analyses of passerine ecological and behavioral evolution and for tests of the causal factors a

11. The relative sizes and asymmetry of kidneys in passerine birds from Australia and North America.
Despite their close taxonomic affinities, nectar-feeding passerine birds from Australia had smaller kidneys, on average, than sympatric passerines of equivalent weight that fed entirely upon insects. Insectivorous passerines from North America had larger kidneys, on average, than comparable insect-feeding passerines from the separate endemic radiation in Aus
