1. Exclusão pulmonar em neonatos - técnicas e o papel do ultrasom
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

2. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

3. Reproductive phenology differs between evergreen and deciduous species in a Northeast Brazilian savanna
ABSTRACT Evergreen (EG) and deciduous (DEC) species exhibit distinct strategies to overcome dry periods and achieve adequate water status for reproduction and growth. Such particularities may result in distinct reproductive strategies between these groups. Thus, we evaluated the phenology of EG and DEC groups, comparing and differentiating their reproductive

4. Amarelos da videira: identificação e análise filogenética dos fitoplasmas, transmissão dos agentes causais e otimização da diagnose / Grapevine yellows: identification and phylogenetic analyses of the phytoplasmas, transmition of the causal agents and diagnosis optimization
Phytoplasmas are wall-less prokaryotes, phloem-limited plant pathogens, belonging to Mollicute class. They are agents of diseases that cause serious damage to a diversity of cultivated especies. Grapevine (Vitis sp) is the third most cultivated fruit crop in the world and it has high economical impact in Brazil. Phytossanitary aspects are important productio

5. Estudos taxonomicos no complexo Kielmeyera coriacea Mart. &Zucc (Clusiaceae) / Taxonomic studies in the Kielmeyera coriacea Mart. &Zucc complex (Clusiaceae)
Kielmeyera Mart. &Zucc. (Clusiaceae) has 47 species and its more recent revision was based on morphological characters. The Coriaceae (Wawra) Saddi series is distinguished from the other series mainly by its coriaceous leaves and shrub/tree habit. In its latest circumscription, the series has two species, K. coriacea, with two subspecies and seven varieties,

6. Bases ecológicas para o manejo de Bemisia tabaci (Genn.) biótipo B (Hemiptera: Aleyrodidae) em sistemas orgânicos de produção de tomate
The whitefly Bemisia tabaci biotype B stands out, among the diverse community of pest herbivores that colonize the tomato crop, due to the direct damages and transmission of several pathogenic viruses (Geminiviridae) causing productivity losses. The spraying of insecticides for its control selects resistant populations and promotes the dispersion of adults t

7. A comunidade de esfingídeos (Lepidoptera, Sphingidae) e plantas esfingófilas numa área de cerrado no sudeste do Brasil: biogeografia e associações mutualísticas / The hawkmoth (Lepidoptera, Sphingidae) and hawkmoth-flower plant community in a Cerrado area of southeastern Brazil: biogeography and mutualistic associations
Hawkmoths (Lepidoptera, Sphingidae) are among the major pollinators in tropical communities. However, in the Cerrado biome little is known about their distribution, species composition, diversity, as well as, their relationships with hawkmoth-flower plant flora. This study aim to describe the hawkmoth fauna and hawkmoth-pollinated plant flora of a Cerrado ar

8. Ecologia e comportamento do Cuxiú-Preto (Chiropotes Satanas) na paisagem fragmentada da Amazônia Oriental. / The Ecology and Behaviour of the Black Bearded Saki (Chiropotes satanas) in the Fragmented Landscape of Eastern Amazonia
Bearded sakis are frugivores specialised for seed predation. The black bearded saki (Chiropotes satanas) is endemic to a densely populated and deforested area in eastern Amazonia in Brazil and is threatened with extinction. The principal objective of this study was to research the behaviour and ecology of two groups of black bearded sakis living under differ

9. Padrões nutricionais de espécies lenhosas do cerrado
A concentração foliar de nutrientes é um importante indicador do estado de nutrição mineral de espécies lenhosas. O Bioma Cerrado apresenta grande diversidade e heterogeneidade de espécies mesmo em fisionomias homogêneas como o cerrado sensu stricto. Esta diversidade se reflete em espécies nativas, que crescem sobre condições edáficas uniformes,

10. Estudo fenologico de especies arboreas de uma floresta tropical em Linhares, ES
This paper aims at describing the periodicity of reproductive and vegetative phenologica1 events of canopy trees in a tropical lowland seasonal moist forest at Línhares, northeaster ES, and relating them to climatic seasonality. Every mo weeks, five individuals of 41 species, distributed withín 15.000 ha of forest, were observed for the occurrence of flowe

11. Tamanho da área de vida e padrão de uso do espaço em grupos de sagüis, Callithrix jacchus (Linnaeus) (Primates, Callitrichidae)
The influence of abundance and distribution of fruits and gums resources in home range size and pattern of range use were investigated in Callithrix jacchus. From October 1996 to January 1998 two groups (QT and PB) that lived in a National Forest/IBAMA-RN in northeastern Brazil (6º5'S, 35º12'W), were observed once a week by instantaneous scan sampling. The

12. Influencia da variação fisionomica da vegetação sobre a composição de aves frugivoras na Mata Atlantica
Due to the alarming rate of deforestation in tropical forests, a better understanding on the organization of biological communities is needed, specifically regarding the interactions between birds and plants. Although this aspect is not often included among the top priorities for biodiversity conservation, it must be considered an important of effort in the
